Android中动画

(1)属性动画

(2)补间动画 

 

(3)帧动画 

   就是加载一系列的图片资源 

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // [1]找到iv控件 用来显示动画效果
        ImageView rocketImage = (ImageView) findViewById(R.id.iv);
        // [2]设置背景资源
        rocketImage.setBackgroundResource(R.drawable.my_anim);
        // [3]获取AnimationDrawable 类型
        AnimationDrawable ad = (AnimationDrawable) rocketImage.getBackground();
        // [4]开始执行动画
        ad.start();

    }

}

在res目录下创建drawable目录，resdrawablemy_anim.xml

<?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/girl_1" android:duration="200" />
    <item android:drawable="@drawable/girl_2" android:duration="200" />
    <item android:drawable="@drawable/girl_3" android:duration="200" />
    <item android:drawable="@drawable/girl_4" android:duration="200" />
    <item android:drawable="@drawable/girl_5" android:duration="200" />
    <item android:drawable="@drawable/girl_5" android:duration="200" />
    <item android:drawable="@drawable/girl_5" android:duration="200" />
    <item android:drawable="@drawable/girl_5" android:duration="200" />
    <item android:drawable="@drawable/girl_6" android:duration="200" />
    <item android:drawable="@drawable/girl_7" android:duration="200" />
    <item android:drawable="@drawable/girl_8" android:duration="200" />
    <item android:drawable="@drawable/girl_9" android:duration="200" />
    <item android:drawable="@drawable/girl_10" android:duration="200" />
    <item android:drawable="@drawable/girl_11" android:duration="200" />
</animation-list>
