Android 幀動畫的使用場景

第一步準備好資源，第二步建立LoadActivity，第三步在anim目錄下建立play_anim.xml檔案

最後一步建立布局檔案。

package com.weixin;

import android.app.Activity;

import android.graphics.drawable.AnimationDrawable;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.ImageView;

public class LoadActivity extends Activity {

private Button btn_load;

private ImageView iv_load;

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_anim);

btn_load = (Button) findViewById(R.id.btn_loadanim);

iv_load = (ImageView) findViewById(R.id.image);

}

public void load(View v) {

iv_load.setBackgroundResource(R.anim.play_anim);

AnimationDrawable frameAnimation = (AnimationDrawable) iv_load

.getBackground();

if (frameAnimation.isRunning()) {

// frameAnimation.setLevel(10);

frameAnimation.stop();

} else {

frameAnimation.stop();

// frameAnimation.setLevel(15);

frameAnimation.start();

}

}

};

play_anim.xml

<?xml version="1.0" encoding="utf-8"?>

<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item android:drawable="@drawable/v_anim1" android:duration= "300"></item>

<item android:drawable="@drawable/v_anim2" android:duration= "300"></item>

<item android:drawable="@drawable/v_anim3" android:duration= "300"></item>

</animation-list>

最後布局檔案

<?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:background="#F000"

    android:orientation="vertical" >

    <Button

        android:id="@+id/btn_loadanim"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_gravity="center"

        android:onClick="load"

        android:text="開啟動畫"

        android:textSize="24sp" />

    <ImageView

        android:id="@+id/image"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:scaleType="fitXY"

        android:src="@drawable/v1" />

</LinearLayout>
