Android---Frame动画示例

Frame动画：

1、找到一组图片c01.jpg,c02.jpg,c03.jpg,c04.jpg,c05.jpg，copy到res/drawable目录下；

2、在res/drawable目录下新建XML文件:frame_anim.xml

[html]
<?xml version="1.0" encoding="utf-8"?>
<animation-list
xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">
<item android:drawable="@drawable/c01" android:duration="500"/>
<item android:drawable="@drawable/c02" android:duration="500"/>
<item android:drawable="@drawable/c03" android:duration="500"/>
<item android:drawable="@drawable/c04" android:duration="500"/>
<item android:drawable="@drawable/c05" android:duration="500"/>
</animation-list>
<?xml version="1.0" encoding="utf-8"?>
<animation-list
xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">
<item android:drawable="@drawable/c01" android:duration="500"/>
<item android:drawable="@drawable/c02" android:duration="500"/>
<item android:drawable="@drawable/c03" android:duration="500"/>
<item android:drawable="@drawable/c04" android:duration="500"/>
<item android:drawable="@drawable/c05" android:duration="500"/>
</animation-list>3、在res/layout目录下新建XML文件:frame_anim_layout.xml

[html]
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scaleType="centerInside"
        android:id="@+id/imgFrame"
        android:background="@drawable/frame_anim"></ImageView>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <Button
            android:text="开始"
            android:id="@+id/btnStart"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1.0"></Button>
        <Button
            android:text="结束"
            android:id="@+id/btnEnd"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1.0"></Button>
    </LinearLayout>
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:scaleType="centerInside"
  android:id="@+id/imgFrame"
  android:background="@drawable/frame_anim"></ImageView>
<LinearLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content">
  <Button
   android:text="开始"
   android:id="@+id/btnStart"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_weight="1.0"></Button>
  <Button
   android:text="结束"
   android:id="@+id/btnEnd"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_weight="1.0"></Button>
</LinearLayout>
</LinearLayout>4、Activity文件中的代码：

[java]
package com.bison;

import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;

public class AnimationDemoActivity extends Activity implements OnClickListener {
    // 开始按钮
    private Button btnStart;
    // 结束按钮
    private Button btnEnd;
    private ImageView imgFrame;
    // 声明Frame动画对象
    private AnimationDrawable frameAnim;

    /** 初始化 */
    public void init() {
        btnStart = (Button) findViewById(R.id.btnStart);
        btnEnd = (Button) findViewById(R.id.btnEnd);
        btnStart.setOnClickListener(this);
        btnEnd.setOnClickListener(this);

        imgFrame = (ImageView) findViewById(R.id.imgFrame);
        // 将ImageView的backgroud声明给Frame动画对象
        frameAnim = (AnimationDrawable) imgFrame.getBackground();
    }
