Android 兩張照片相互淡出

在res/drawable下面新建一個stylr.xml

1. <?xml version="1.0" encoding="UTF-8"?>
2. <transition xmlns:Android="http://schemas.android.com/apk/res/android">
3. <item android:drawable="@drawable/badtz1"/>
4. <item android:drawable="@drawable/badtz2"/>
5. </transition>

1. public class Draw01Activity extends Activity {
2. /** Called when the activity is first created. */
4. @Override
5. public void onCreate(Bundle savedInstanceState) {
6. super.onCreate(savedInstanceState);
7. setContentView(R.layout.main);
9. Resources res = getResources();
10. TransitionDrawable transition = (TransitionDrawable) res.getDrawable(R.drawable.stylr);
11. ImageView mImageView = (ImageView) findViewById(R.id.imageView1);
12. mImageView.setImageDrawable(transition);
13. //2秒開始轉換
14. transition.startTransition(2000);
15. }
