android - Android图像旋转

我希望图像旋转不定时间........这意味着我想循环播放。这是我的尝试，但不幸的是它没有用。有什么建议么？

package com.android.test;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Matrix;
import android.graphics.drawable.BitmapDrawable;
import android.os.Bundle;
import android.widget.ImageView;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;
import android.widget.ImageView.ScaleType;

public class imagerotate extends Activity {
 int x=1;
 int y=3;

     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         LinearLayout linearLayout = new LinearLayout(this);

         while (y==3) {
   Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.icon);

   int width = bitmap.getWidth();
   int height = bitmap.getHeight();

   Matrix matrix = new Matrix();
   matrix.postRotate(x);

   Bitmap rotatedBitmap = Bitmap.createBitmap(bitmap, 0, 0, width,height, matrix, true);
   BitmapDrawable bmd = new BitmapDrawable(rotatedBitmap);

   ImageView imageView = new ImageView(this);
   imageView.setImageDrawable(bmd);
   imageView.setScaleType(ScaleType.CENTER);

   linearLayout.addView(imageView, new LinearLayout.LayoutParams(
     LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
   setContentView(linearLayout);

   x+=1;
   }
     }
 }

最佳答案

您不能循环进入主线程。这将立即使您的应用无响应。考虑使用RotateAnimation-请参阅文档链接。
