Android 两张照片相互淡出

在res/drawable下面新建一个stylr.xml

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

public class Draw01Activity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); TransitionDrawable transition = (TransitionDrawable) res.getDrawable(R.drawable.stylr); ImageView mImageView = (ImageView) findViewById(R.id.imageView1); mImageView.setImageDrawable(transition); //2秒开始转换 transition.startTransition(2000); }
