AnimationUtil動畫工具類

簡單的練手程式

上代碼

package mars.com;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.view.animation.Animation;import android.view.animation.AnimationUtils;import android.widget.Button;import android.widget.ImageView;public class Demo_Activity extends Activity {private Button button1;private Button button2;private ImageView image;private Animation loadAnimation;public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);button1 = (Button) findViewById(R.id.button1);button2 = (Button) findViewById(R.id.button2);image = (ImageView) findViewById(R.id.image);// 以下是監聽器button1.setOnClickListener(new OnClickListener() {public void onClick(View v) {loadAnimation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.anim);image.setAnimation(loadAnimation);// 為控制項設定動畫loadAnimation.setFillAfter(true);// 停留在結束為止loadAnimation.setFillEnabled(true);//loadAnimation.startNow();// 開始動畫}});button2.setOnClickListener(new OnClickListener() {public void onClick(View v) {loadAnimation.cancel();// 取消動畫}});}}

main.xml代碼如下

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <Button        android:id="@+id/button1"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="開始動畫" />    <Button        android:id="@+id/button2"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="停止動畫" />    <ImageView        android:id="@+id/image"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:src="@drawable/ic_launcher" /></LinearLayout>

設定檔anim.anim.xml檔案如下

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" >    <translate        android:duration="3000"        android:toXDelta="0"        android:toYDelta="300" />    <rotate        android:duration="3000"        android:fromDegrees="270"        android:pivotX="50%"        android:pivotY="50%"        android:toDegrees="360" /></set>

運行效果如下
