Android新装应用apk运行动画 ViewFlipper(翻转视图)
其实这么个意思,就是每次我们下载一个新的应用,他都有左右滑动看这个应用的介绍,或者宣传之类的,刚开始感觉好牛逼。
今天学了这个http://blog.youkuaiyun.com/coder_pig/article/details/48734807
感觉不在那么高大上了。。

好的,我们开始学习吧
自动滑动过程截图
不多说了,老规矩,贴代码
每个页面的布局都是一个简单的ImageView
page_help_one.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@mipmap/ic_help_view_1"/>
</LinearLayout>
page_help_two.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@mipmap/ic_help_view_2"/>
</LinearLayout>
page_help_three.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@mipmap/ic_help_view_3"/>
</LinearLayout>
page_help_four.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@mipmap/ic_help_view_4"/>
</LinearLayout>
两个进入以及 离开的动画:
right_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="2000"
android:fromXDelta="100%p"
android:toXDelta="0" />
</set>
right_out.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="2000"
android:fromXDelta="0"
android:toXDelta="-100%p" />
</set>
图片就不用了吧。。。
布局文件:activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<ViewFlipper
android:id="@+id/vflp_help"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:inAnimation="@anim/right_in"
android:outAnimation="@anim/right_out"
android:flipInterval="3000">
<include layout="@layout/page_help_one" />
<include layout="@layout/page_help_two" />
<include layout="@layout/page_help_three" />
<include layout="@layout/page_help_four" />
</ViewFlipper>
</RelativeLayout>
展示视图控制文件:MainActivity
package com.yang.viewflipperstaticdemo;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ViewFlipper;
public class MainActivity extends AppCompatActivity {
private ViewFlipper vflp_help;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
vflp_help = (ViewFlipper) findViewById(R.id.vflp_help);
vflp_help.startFlipping();
}
}
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.yang.viewflipperstaticdemo">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
看他自己在动,十分不爽是吧
我们需要的是可操作。。
这是代码目录
别及大神教我们了。。
再增加两个进入以及 离开的动画:
left_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="500"
android:fromXDelta="-100%p"
android:toXDelta="0" />
</set>
left_out.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="500"
android:fromXDelta="0"
android:toXDelta="100%p" />
</set>
新增了:MainActivityRun
package com.yang.viewflipperstaticdemo;
import android.content.Context;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.widget.ImageView;
import android.widget.ViewFlipper;
public class MainActivityRun extends AppCompatActivity {
private Context mContext;
private ViewFlipper vflp_help;
private int[] resId = {R.mipmap.ic_help_view_1,R.mipmap.ic_help_view_2,
R.mipmap.ic_help_view_3,R.mipmap.ic_help_view_4};
private final static int MIN_MOVE = 200; //最小距离
private MyGestureListener mgListener;
private GestureDetector mDetector;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mContext = MainActivityRun.this;
//实例化SimpleOnGestureListener与GestureDetector对象
mgListener = new MyGestureListener();
mDetector = new GestureDetector(this, mgListener);
vflp_help = (ViewFlipper) findViewById(R.id.vflp_help);
//动态导入添加子View
for(int i = 0;i < resId.length;i++){
vflp_help.addView(getImageView(resId[i]));
}
}
//重写onTouchEvent触发MyGestureListener里的方法
@Override
public boolean onTouchEvent(MotionEvent event) {
return mDetector.onTouchEvent(event);
}
//自定义一个GestureListener,这个是View类下的,别写错哦!!!
private class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float v, float v1) {
if(e1.getX() - e2.getX() > MIN_MOVE){
vflp_help.setInAnimation(mContext,R.anim.right_in);
vflp_help.setOutAnimation(mContext, R.anim.right_out);
vflp_help.showNext();
}else if(e2.getX() - e1.getX() > MIN_MOVE){
vflp_help.setInAnimation(mContext,R.anim.left_in);
vflp_help.setOutAnimation(mContext, R.anim.left_out);
vflp_help.showPrevious();
}
return true;
}
}
private ImageView getImageView(int resId){
ImageView img = new ImageView(this);
img.setBackgroundResource(resId);
return img;
}
}
怎么么让他运行呢。。。别忘了改AndroidManifest.xml,区别自己看去吧
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.yang.viewflipperstaticdemo">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivityRun"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
代码下载
本文中的代码已经在文中全部出现过了,为什么还需要一个下载币呢,是因为我的下载币不够用了额,下载其他大神的代码,需要,所以请赞助一下吧。当然你不想赞助的话,你可以在文章中一个一个的copy,绝对的一模一样,绝对的开源,赞助一个下载币吧
