本文详细介绍Glide图片加载库的功能特性，包括网络图片加载、缓存处理、高斯模糊等高级功能实现，并提供定制Glide模块的方法及示例代码。

Glide是 Google推荐的图片加载库,它可以支持来自url,Android资源,文件,Uri中的图片加载,同时还支持gif图片的加载,以及各种图片显示前的bitmap处理(例如:圆角图片,圆形图片,高斯模糊,旋转,灰度等等),缓存处理,请求优先级处理,动画处理,缩略图处理,图片大小自定义等等.可谓是非常的强大.

1.添加Glide库

需要在build.gradle中加入依赖,目前最新的版本是3.7.0,Glide库地址

<code class="language-gradle hljs bash has-numbering"> compile <span class="hljs-string">'com.github.bumptech.glide:glide:3.7.0'</span></code><ul style="" class="pre-numbering"><li>1</li></ul>

2.加载网络图片

6.加载gif图片

<code class="language-java hljs  has-numbering">
<span class="hljs-keyword">public</span> <span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">TestGlideActivity</span> <span class="hljs-keyword">extends</span> <span class="hljs-title">Activity</span> {</span>
    <span class="hljs-annotation">@Override</span>
    <span class="hljs-keyword">protected</span> <span class="hljs-keyword">void</span> <span class="hljs-title">onCreate</span>(Bundle savedInstanceState) {

        setContentView(R.layout.activity_test);
        ImageView targetView = (ImageView) findViewById(R.id.iv_target);
        Glide.with(<span class="hljs-keyword">this</span>).
                load(R.drawable.smail).
                asGif().<span class="hljs-comment">//注意:这里显示的指明了要加载的是gif图片,当然即使不指明,glide也会自己判断.</span>
                into(targetView);
    }
}</code><ul style="" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li><li>7</li><li>8</li><li>9</li><li>10</li><li>11</li><li>12</li><li>13</li></ul>

效果图:
这里写图片描述

7.设置默认图片和加载失败时显示的图片

<code class="language-java hljs  has-numbering">
<span class="hljs-keyword">public</span> <span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">TestGlideActivity</span> <span class="hljs-keyword">extends</span> <span class="hljs-title">Activity</span> {</span>
    <span class="hljs-annotation">@Override</span>
    <span class="hljs-keyword">protected</span> <span class="hljs-keyword">void</span> <span class="hljs-title">onCreate</span>(Bundle savedInstanceState) {
        <span class="hljs-keyword">super</span>.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        ImageView targetView = (ImageView) findViewById(R.id.iv_target);
        Glide.with(<span class="hljs-keyword">this</span>).
                load(R.drawable.test).
                asBitmap().
                placeholder(R.drawable.bg_loading).<span class="hljs-comment">//加载中显示的图片</span>
                error(R.drawable.bg_error).<span class="hljs-comment">//加载失败时显示的图片</span>
                into(targetView);
    }
}</code><ul style="" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li><li>7</li><li>8</li><li>9</li><li>10</li><li>11</li><li>12</li><li>13</li><li>14</li><li>15</li></ul>

8.淡入显示效果

<code class="language-java hljs  has-numbering">
<span class="hljs-keyword">public</span> <span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">TestGlideActivity</span> <span class="hljs-keyword">extends</span> <span class="hljs-title">Activity</span> {</span>
    <span class="hljs-annotation">@Override</span>
    <span class="hljs-keyword">protected</span> <span class="hljs-keyword">void</span> <span class="hljs-title">onCreate</span>(Bundle savedInstanceState) {
        <span class="hljs-keyword">super</span>.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        ImageView targetView = (ImageView) findViewById(R.id.iv_target);
        Glide.with(<span class="hljs-keyword">this</span>).
                load(R.drawable.test).
                placeholder(R.drawable.bg_loading).<span class="hljs-comment">//加载中显示的图片</span>
                error(R.drawable.bg_error).<span class="hljs-comment">//加载失败时显示的图片</span>
                crossFade().<span class="hljs-comment">//淡入显示,注意:如果设置了这个,则必须要去掉asBitmap</span>
                into(targetView);
    }
}</code><ul style="" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li><li>7</li><li>8</li><li>9</li><li>10</li><li>11</li><li>12</li><li>13</li><li>14</li><li>15</li></ul>

另外,crossFade还可以接收一个参数来设置淡入显示效果的持续时间,crossFade(int duration);
如果你想直接显示图片,而不是淡入显示图片,则可以通过dontAnimate()方法设置.

9.调整图片像素大小

<code class="language-java hljs  has-numbering">
<span class="hljs-keyword">public</span> <span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">TestGlideActivity</span> <span class="hljs-keyword">extends</span> <span class="hljs-title">Activity</span> {</span>
    <span class="hljs-annotation">@Override</span>
    <span class="hljs-keyword">protected</span> <span class="hljs-keyword">void</span> <span class="hljs-title">onCreate</span>(Bundle savedInstanceState) {
        <span class="hljs-keyword">super</span>.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        ImageView targetView = (ImageView) findViewById(R.id.iv_target);
        Glide.with(<span class="hljs-keyword">this</span>).
                load(R.drawable.test).
                placeholder(R.drawable.bg_loading).<span class="hljs-comment">//加载中显示的图片</span>
                error(R.drawable.bg_error).<span class="hljs-comment">//加载失败时显示的图片</span>
                crossFade(<span class="hljs-number">1000</span>).<span class="hljs-comment">//淡入显示的时间,注意:如果设置了这个,则必须要去掉asBitmap</span>
                override(<span class="hljs-number">80</span>,<span class="hljs-number">80</span>).<span class="hljs-comment">//设置最终显示的图片像素为80*80,注意:这个是像素,而不是控件的宽高</span>
                into(targetView);
    }
}</code><ul style="" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li><li>7</li><li>8</li><li>9</li><li>10</li><li>11</li><li>12</li><li>13</li><li>14</li><li>15</li><li>16</li></ul>

10.设置CenterCrop,FitCenter

CenterCrop,FitCenter都是对目标图片进行裁剪,了解过ImageView的ScaleType属性就知道,这2种裁剪方式在ImageView上也是有的,分别对应ImageView的ImageView.ScaleType.CENTER_CROP和mageView.ScaleType.FIT_CENTER的.

<code class="language-java hljs  has-numbering">
<span class="hljs-keyword">public</span> <span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">TestGlideActivity</span> <span class="hljs-keyword">extends</span> <span class="hljs-title">Activity</span> {</span>
    <span class="hljs-annotation">@Override</span>
    <span class="hljs-keyword">protected</span> <span class="hljs-keyword">void</span> <span class="hljs-title">onCreate</span>(Bundle savedInstanceState) {
        <span class="hljs-keyword">super</span>.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        ImageView targetView = (ImageView) findViewById(R.id.iv_target);
        targetView.setScaleType(ImageView.ScaleType.FIT_CENTER);
        Glide.with(<span class="hljs-keyword">this</span>).
                load(R.drawable.test).
                placeholder(R.drawable.bg_loading).<span class="hljs-comment">//加载中显示的图片</span>
                error(R.drawable.bg_error).<span class="hljs-comment">//加载失败时显示的图片</span>
                crossFade(<span class="hljs-number">1000</span>).<span class="hljs-comment">//淡入淡出,注意:如果设置了这个,则必须要去掉asBitmap</span>
                override(<span class="hljs-number">80</span>,<span class="hljs-number">80</span>).<span class="hljs-comment">//设置最终显示的图片像素为80*80,注意:这个是像素,而不是控件的宽高</span>
                centerCrop().<span class="hljs-comment">//中心裁剪,缩放填充至整个ImageView</span>
                into(targetView);
    }
}
</code><ul style="" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li><li>7</li><li>8</li><li>9</li><li>10</li><li>11</li><li>12</li><li>13</li><li>14</li><li>15</li><li>16</li><li>17</li><li>18</li><li>19</li></ul>

11.缓存策略设置

内存缓存设置,通过skipMemoryCache(boolean)来设置是否需要缓存到内存,默认是会缓存到内存的.

<code class="language-java hljs  has-numbering"><span class="hljs-javadoc">/**

<span class="hljs-keyword">public</span> <span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">TestGlideActivity</span> <span class="hljs-keyword">extends</span> <span class="hljs-title">Activity</span> {</span>

        setContentView(R.layout.activity_test);
        ImageView targetView = (ImageView) findViewById(R.id.iv_target);
        targetView.setScaleType(ImageView.ScaleType.FIT_CENTER);
        Glide.with(<span class="hljs-keyword">this</span>).
                load(R.drawable.test).
                placeholder(R.drawable.bg_loading).<span class="hljs-comment">//加载中显示的图片</span>
                error(R.drawable.bg_error).<span class="hljs-comment">//加载失败时显示的图片</span>

磁盘缓存,磁盘缓存通过diskCacheStrategy(DiskCacheStrategy)来设置,DiskCacheStrategy一共有4种模式:

DiskCacheStrategy.NONE:什么都不缓存
DiskCacheStrategy.SOURCE:仅缓存原图(全分辨率的图片)
DiskCacheStrategy.RESULT:仅缓存最终的图片,即修改了尺寸或者转换后的图片
DiskCacheStrategy.ALL:缓存所有版本的图片,默认模式

12.缓存设置

在GlideModule 中,我们可以设置磁盘缓存的位置,磁盘缓存的大小和内存缓存的大小,同时还可以设置图片的显示质量.

要是用GlideModule ,需要创建它的实现类,然后在manifests中申明实现类的全类路径:

<code class="language-xml hljs  has-numbering">  <span class="hljs-tag"><<span class="hljs-title">meta-data
</span>            <span class="hljs-attribute">android:name</span>=<span class="hljs-value">"com.example.mchenys.httputilsdemo.image.glide.module.SimpleGlideModule"</span>
            <span class="hljs-attribute">android:value</span>=<span class="hljs-value">"GlideModule"</span> /></span></code><ul style="" class="pre-numbering"><li>1</li><li>2</li><li>3</li></ul>

GlideModule 的实现类,需要实现applyOptions方法:

<code class="language-java hljs  has-numbering"><span class="hljs-javadoc">/**
 * 所以你知道要创建一个额外的类去定制 Glide。
 * 下一步是要全局的去声明这个类，让 Glide 知道它应该在哪里被加载和使用。
 * Glide 会扫描 AndroidManifest.xml 为 Glide module 的 meta 声明。
 * 因此，你必须在 AndroidManifest.xml 的 <application> 标签内去声明这个SimpleGlideModule。

13.设置图片请求的优先级

Glide 可以用 Priority 枚举来设置图片的加载优先级,这样我们就可以针对那些需要显示的图片设置高的优先级了.
Priority 有4种级别:
Priority.LOW
Priority.NORMAL
Priority.HIGH
Priority.IMMEDIATE
例如:

<code class="language-java hljs  has-numbering"> <span class="hljs-javadoc">/**
     * 高优先级加载
     *<span class="hljs-javadoctag"> @param</span> url
     *<span class="hljs-javadoctag"> @param</span> imageView

14.设置加载缩略图

通过设置缩略图,我们可以在显示目标图片之前先展示一个第分辨率或者其他图片,当全分辨率的目标图片在后台加载完成后,
Glide会自动切换显示全像素的目标图片.

设置缩略图有2种方式:
通过thumbnail(float)指定0.0f~1.0f的原始图像大小,例如全像素的大小是500*500,如果设置为thumbnail为0.1f,即目标图片的10%,显示的缩略图大小就是50*50;

        setContentView(R.layout.activity_test);
        ImageView targetView = (ImageView) findViewById(R.id.iv_target);

        Glide.with(<span class="hljs-keyword">this</span>).
                load(R.drawable.test).

15.Transformations Bitmap

在显示目标图片之前,我们可以对目标图片的Bitmap进行相应的处理,例如::圆角图片,圆形图片,高斯模糊,旋转,灰度等等.
只需要实现Transformation接口即可,该接口的transform方法会返回显示图片前的Bitmap对象,在该方法中对
Bitmap的任何处理,都会影响到最终的显示结果.
当然,如果你只是想要对图片做常规的 bitmap 转换，你可以继承抽象类BitmapTransformation,它简化了Transformation接口的实现，这应该能覆盖大部分的应用场景了。

使用的时候,通过transform(Transformation… transformations)来设置.例如:

<code class="language-java hljs  has-numbering"><span class="hljs-keyword">public</span> <span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">TestGlideActivity</span> <span class="hljs-keyword">extends</span> <span class="hljs-title">Activity</span> {</span>

        <span class="hljs-keyword">super</span>.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        ImageView targetView = (ImageView) findViewById(R.id.iv_target);
        Glide.with(<span class="hljs-keyword">this</span>).
                load(R.drawable.test).
                asBitmap().
                transform(<span class="hljs-keyword">new</span> BlurTransformation(<span class="hljs-keyword">this</span>)).<span class="hljs-comment">//高斯模糊处理</span>
                into(targetView);
    }

RenderScript处理高斯模糊

android4.3之后可使用,需要在build.gradle中配置:

<code class="language-gradle hljs cs has-numbering">defaultConfig {

        <span class="hljs-comment">//BlurTransformation</span>
        renderscriptTargetApi <span class="hljs-number">23</span>
        renderscriptSupportModeEnabled <span class="hljs-keyword">true</span>
}</code><ul style="" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li></ul>

<code class="language-java hljs  has-numbering"><span class="hljs-keyword">public</span> <span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">RSBlur</span> {</span>

    <span class="hljs-annotation">@TargetApi</span>(Build.VERSION_CODES.JELLY_BEAN_MR2)
    <span class="hljs-keyword">public</span> <span class="hljs-keyword">static</span> Bitmap <span class="hljs-title">blur</span>(Context context, Bitmap blurredBitmap, <span class="hljs-keyword">int</span> radius) <span class="hljs-keyword">throws</span> RSRuntimeException {

            Allocation input = Allocation.createFromBitmap(rs, blurredBitmap, Allocation.MipmapControl.MIPMAP_NONE,
                    Allocation.USAGE_SCRIPT);
            Allocation output = Allocation.createTyped(rs, input.getType());
            ScriptIntrinsicBlur blur = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));

            blur.setInput(input);
            blur.setRadius(radius);
            blur.forEach(output);
            output.copyTo(blurredBitmap);
            rs.destroy();
        } <span class="hljs-keyword">catch</span> (RSRuntimeException e) {
            blurredBitmap = FastBlur.blur(blurredBitmap, radius, <span class="hljs-keyword">true</span>);
        }
        <span class="hljs-keyword">return</span> blurredBitmap;
    }
}</code><ul style="" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li><li>7</li><li>8</li><li>9</li><li>10</li><li>11</li><li>12</li><li>13</li><li>14</li><li>15</li><li>16</li><li>17</li><li>18</li><li>19</li><li>20</li><li>21</li><li>22</li></ul>

16.动画处理

通过animate()方法可以设置xml文件定义的4种补间动画(alpha、scale、translate、rotate)
例如:

res\anim\left_in.xml

<code class="language-xml hljs  has-numbering">
<span class="hljs-pi"><?xml version="1.0" encoding="utf-8"?></span>
<span class="hljs-tag"><<span class="hljs-title">set</span> <span class="hljs-attribute">xmlns:android</span>=<span class="hljs-value">"http://schemas.android.com/apk/res/android"</span>></span>
    <span class="hljs-tag"><<span class="hljs-title">translate
</span>        <span class="hljs-attribute">android:duration</span>=<span class="hljs-value">"@android:integer/config_mediumAnimTime"</span>
        <span class="hljs-attribute">android:fromXDelta</span>=<span class="hljs-value">"-50%p"</span>
        <span class="hljs-attribute">android:toXDelta</span>=<span class="hljs-value">"0"</span>/></span>
    <span class="hljs-tag"><<span class="hljs-title">alpha
</span>        <span class="hljs-attribute">android:duration</span>=<span class="hljs-value">"@android:integer/config_mediumAnimTime"</span>
        <span class="hljs-attribute">android:fromAlpha</span>=<span class="hljs-value">"0.0"</span>
        <span class="hljs-attribute">android:toAlpha</span>=<span class="hljs-value">"1.0"</span>/></span>
<span class="hljs-tag"></<span class="hljs-title">set</span>></span></code><ul style="" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li><li>7</li><li>8</li><li>9</li><li>10</li><li>11</li><li>12</li></ul>

使用方式:

<code class="language-java hljs  has-numbering"><span class="hljs-keyword">public</span> <span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">TestGlideActivity</span> <span class="hljs-keyword">extends</span> <span class="hljs-title">Activity</span> {</span>
    <span class="hljs-annotation">@Override</span>
    <span class="hljs-keyword">protected</span> <span class="hljs-keyword">void</span> <span class="hljs-title">onCreate</span>(Bundle savedInstanceState) {
        <span class="hljs-keyword">super</span>.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        ImageView targetView = (ImageView) findViewById(R.id.iv_target);
        Glide.with(<span class="hljs-keyword">this</span>).
                load(R.drawable.test).
                asBitmap().
                animate(R.anim.left_in).<span class="hljs-comment">//加载xml文件定义的动画</span>
                into(targetView);
    }
}</code><ul style="" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li><li>7</li><li>8</li><li>9</li><li>10</li><li>11</li><li>12</li><li>13</li></ul>

处理此外,还可以通过animate指定属性动画:

<code class="language-xml hljs  has-numbering">public class TestGlideActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        ImageView targetView = (ImageView) findViewById(R.id.iv_target);

        ViewPropertyAnimation.Animator animationObject = new ViewPropertyAnimation.Animator() {
            @Override
            public void animate(View view) {
                //设置属性动画
                ObjectAnimator moveIn = ObjectAnimator.ofFloat(view, "translationX", -500f, 0f);
                ObjectAnimator rotate = ObjectAnimator.ofFloat(view, "rotation", 0f, 360f);
                ObjectAnimator fadeInOut = ObjectAnimator.ofFloat(view, "alpha", 1f, 0f, 1f);
                ObjectAnimator moveTop = ObjectAnimator.ofFloat(view, "translationY", 0f, -2000, 0f);
                AnimatorSet animSet = new AnimatorSet();
                //先左进,然后旋转伴随淡入效果,最后移动向上
                animSet.play(rotate).with(fadeInOut).after(moveIn).before(moveTop);
                animSet.setDuration(5000);
                animSet.start();
            }
        };
        Glide.with(this).
                load(R.drawable.test).
                asBitmap().
                animate(animationObject).//加载属性动画
                into(targetView);
    }
}
