android 进度条的样式

该类型进度条也就是一个表示运转的过程，例如发送短信，连接网络等等，表示一个过程正在执行中。

一般只要在XML布局中定义就可以了。

1. <progressBar android:id="@+id/widget43"
   
2. <wbr><wbr><wbr><wbr>android:layout_width="wrap_content"<br></wbr></wbr></wbr></wbr>
3. <wbr><wbr><wbr><wbr>android:layout_height="wrap_content"<wbr><wbr><br></wbr></wbr></wbr></wbr></wbr></wbr>
4. <wbr><wbr><wbr><wbr>android:layout_gravity="center_vertical"&gt;<br></wbr></wbr></wbr></wbr>
5. </ProgressBar>

此时，没有设置它的风格，那么它就是圆形的，一直会旋转的进度条。

各大小样式圆形ProgressBar


超大号圆形ProgressBar


此时，给设置一个style风格属性后，该ProgressBar就有了一个风格，这里大号ProgressBar的风格是：

1. style="?android:attr/progressBarStyleLarge"

完整XML定义是：

1. <progressBar android:id="@+id/widget196"
   
2. <wbr><wbr><wbr><wbr>android:layout_width="wrap_content"<br></wbr></wbr></wbr></wbr>
3. <wbr><wbr><wbr><wbr>android:layout_height="wrap_content"<br></wbr></wbr></wbr></wbr>
4. <wbr><wbr><wbr><wbr>style="?android:attr/progressBarStyleLarge"&gt;<br></wbr></wbr></wbr></wbr>
5. </ProgressBar>

小号圆形ProgressBar



小号ProgressBar对应的风格是：

1. style="?android:attr/progressBarStyleSmall"

完整XML定义是：

1. <progressBar android:id="@+id/widget108"
   
2. <wbr><wbr><wbr><wbr>android:layout_width="wrap_content"<br></wbr></wbr></wbr></wbr>
3. <wbr><wbr><wbr><wbr>android:layout_height="wrap_content"<br></wbr></wbr></wbr></wbr>
4. <wbr><wbr><wbr><wbr>style="?android:attr/progressBarStyleSmall"&gt;<br></wbr></wbr></wbr></wbr>
5. </ProgressBar>

标题型圆形ProgressBar





标题型ProgressBar对应的风格是：

1. style="?android:attr/progressBarStyleSmallTit<wbr>le" </wbr>

完整XML定义是：

1. <progressBar android:id="@+id/widget110"
   
2. <wbr><wbr> android:layout_width="wrap_content"<br></wbr></wbr>
3. <wbr><wbr> android:layout_height="wrap_content"<br></wbr></wbr>
4. <wbr><wbr> style="?android:attr/progressBarStyleSmallTit<wbr>le"&gt;<br></wbr></wbr></wbr>
5. </ProgressBar>

代码中实现：

1. @Override
   
2. <wbr><wbr> protected void onCreate(Bundle savedInstanceState) {<br></wbr></wbr>
3. <wbr><wbr><wbr><wbr><wbr><wbr>// TODO Auto-generated method stub<br></wbr></wbr></wbr></wbr></wbr></wbr>
4. <wbr><wbr><wbr><wbr><wbr><wbr>super.onCreate(savedInstanceState);<br></wbr></wbr></wbr></wbr></wbr></wbr>
5. <wbr><wbr><wbr><wbr><wbr><wbr>requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);<br></wbr></wbr></wbr></wbr></wbr></wbr>
6. <wbr><wbr><wbr><wbr><wbr><wbr>//请求窗口特色风格，这里设置成不明确的进度风格<br></wbr></wbr></wbr></wbr></wbr></wbr>
7. <wbr><wbr><wbr><wbr><wbr><wbr>setContentView(R.layout.second);<br></wbr></wbr></wbr></wbr></wbr></wbr>
8. <wbr><wbr><wbr><wbr><wbr><wbr>setProgressBarIndetermin<wbr>ateVisibility(true);<br></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
9. <wbr><wbr><wbr><wbr><wbr><wbr>//设置标题栏中的不明确的进度条是否可以显示<br></wbr></wbr></wbr></wbr></wbr></wbr>
10. <wbr><wbr> } </wbr></wbr>

长形进度条

布局中的长形进度条


①首先在XML进行布局

1. <progressBar android:id="@+id/progressbar_updown"
   
2. <wbr><wbr><wbr><wbr><wbr><wbr>android:layout_width="200dp"<br></wbr></wbr></wbr></wbr></wbr></wbr>
3. <wbr><wbr><wbr><wbr><wbr><wbr>android:layout_height="wrap_content"<br></wbr></wbr></wbr></wbr></wbr></wbr>
4. <wbr><wbr><wbr><wbr><wbr><wbr>style="?android:attr/progressBarStyleHorizont<wbr>al"<br></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
5. <wbr><wbr><wbr><wbr><wbr><wbr>android:layout_gravity="center_vertical"<br></wbr></wbr></wbr></wbr></wbr></wbr>
6. <wbr><wbr><wbr><wbr><wbr><wbr>android:max="100"<br></wbr></wbr></wbr></wbr></wbr></wbr>
7. <wbr><wbr><wbr><wbr><wbr><wbr>android:progress="50"<br></wbr></wbr></wbr></wbr></wbr></wbr>
8. <wbr><wbr><wbr><wbr><wbr><wbr>android:secondaryProgress="70"<wbr><wbr> &gt; </wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

讲解：

style="?android:attr/progressBarStyleHorizont<wbr>al"<wbr><wbr><br></wbr></wbr></wbr>	设置风格为长形
android:max="100"<wbr><wbr><br></wbr></wbr>	最大进度值为100
android:progress="50"<wbr><wbr><br></wbr></wbr>	初始化的进度值
android:secondaryProgress="70"	初始化的底层第二个进度值
android:layout_gravity="center_vertical"<wbr><wbr><br></wbr></wbr>	垂直居中

②代码中运用

1. private ProgressBar myProgressBar;
   
2. //定义ProgressBar
   
3. myProgressBar = (ProgressBar) findViewById(R.id.progressbar_updown);
   
4. //ProgressBar通过ID来从XML中获取
   
5. myProgressBar.incrementProgressBy(5);
   
6. //ProgressBar进度值增加5
   
7. myProgressBar.incrementProgressBy(-5);
   
8. //ProgressBar进度值减少5
   
9. myProgressBar.incrementSecondaryProgre<wbr>ssBy(5);<br></wbr>
10. //ProgressBar背后的第二个进度条 进度值增加5
    
11. myProgressBar.incrementSecondaryProgre<wbr>ssBy(-5);<br></wbr>
12. //ProgressBar背后的第二个进度条 进度值减少5

页面标题中的长形进度条


代码实现：
①先设置一下窗口风格特性

1. requestWindowFeature(Window.FEATURE_PROGRESS);
   
2. //请求一个窗口进度条特性风格
   
3. setContentView(R.layout.main);
   
4. setProgressBarVisibility<wbr>(true);<br></wbr>
5. //设置进度条可视

②然后设置进度值

1. setProgress(myProgressBar.getProgress() * 100);
   
2. //设置标题栏中前景的一个进度条进度值
   
3. setSecondaryProgress(myProgressBar.getSecondaryProgress() * 100);
   
4. //设置标题栏中后面的一个进度条进度值
   
5. //ProgressBar.getSecondaryProgress() 是用来获取其他进度条的进度值

ProgressDialog

<wbr><wbr></wbr></wbr><wbr><wbr><br> ProgressDialog一般用来表示一个系统任务或是开启任务时候的进度，有一种稍等的意思。<br> 代码实现：<br><br></wbr></wbr>

1. <wbr><wbr>ProgressDialog mypDialog=new ProgressDialog(this);<br></wbr></wbr>
2. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>//实例化<br></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

6. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>//设置ProgressDialog 标题<br></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

12. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>//设置ProgressDialog 的一个Button<br></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
13. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>mypDialog.setIndeterminate(false);<br></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
14. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>//设置ProgressDialog 的进度条是否不明确<br></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
15. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>mypDialog.setCancelable(true);<br></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
