Animation动画

1、创建动画展示的xml布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    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"
    android:orientation="vertical"
    tools:context="com.ui.demo.custom.AnimationActivity">
    <ImageView
        android:id="@+id/image2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/xiaoxiong"
        />
    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="button"/>
</LinearLayout>

2、创建动画效果

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <!--定义缩放变换-->
    <scale android:fromXScale="1.0"
           android:toXScale="1.4"
           android:fromYScale="1.0"
           android:toYScale="0.6"
           android:pivotX="50%"
           android:pivotY="50%"
           android:fillAfter="true"
           android:duration="2000"
           />
    <!--定义位置变换-->
    <translate
        android:fromXDelta="10"
        android:toXDelta="130"
        android:fromYDelta="30"
        android:toYDelta="-80"
        android:duration="2000"/>


</set>

3、创建展示的Activity

public class AnimationActivity extends Activity
{

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_animation);
        final ImageView imageView = (ImageView) findViewById(R.id.image2);
        final Animation animation = AnimationUtils.loadAnimation(this,R.anim.my_anim);
        //设置动画结束后保留结束状态
        animation.setFillAfter(true);
        Button button = (Button) findViewById(R.id.button);
        button.setonClickListener(new View.OnClickListener()
        {
            @Override public void onClick(View v)
            {
                //开始动画
                imageView.startAnimation(animation);
            }
        });
    }
}
