android动画实现-Tween animation(三)

第一步：创建动画文件在res/anim下

<set xmlns:android="http://schemas.android.com/apk/res/android"

android:shareInterpolator="true" >

<scale

android:interpolator="@android:anim/accelerate_decelerate_interpolator"

android:fromXScale="1.0"

android:toXScale="1.4"

android:fromYScale="1.0"

android:toYScale="0.6"

android:pivotX="50%"

android:pivotY="50%"

android:fillAfter="false"

android:duration="700" />

<set

android:interpolator="@android:anim/accelerate_interpolator"

android:startOffset="700" >

<scale

android:fromXScale="1.4"

android:toXScale="0.0"

android:fromYScale="0.6"

android:toYScale="0.0"

android:pivotX="50%"

android:pivotY="50%"

android:duration="400" />

<rotate

android:fromDegrees="0"

android:toDegrees="-45"

android:toYScale="0.0"

android:pivotX="50%"

android:pivotY="50%"

android:duration="400" />

</set>

</set>

第二步：布局文件

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

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

<TextView

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="@string/hello"

/>

<ImageView

android:id="@+id/im"

android:src="@drawable/aa1"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

/>

</LinearLayout>

第三步：测试

public class AnimationTestActivity extends Activity {

private ImageView im=null;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

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

Animation hyperspaceJump = AnimationUtils.loadAnimation(this, R.anim.animation_1);

image.startAnimation(hyperspaceJump);

}

}
