先看效果吧:
public class MainActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView imageView;
Matrix mMatrix = new Matrix();
imageView = (ImageView) findViewById(R.id.myimage);
Bitmap bmp = ((BitmapDrawable) getResources().getDrawable(
R.drawable.icon_150_380882090)).getBitmap();
Camera camera = new Camera();
camera.save();
camera.rotateY(50f);
//camera.rotateX(50f);
//camera.rotateZ(50f);
camera.getMatrix(mMatrix);
camera.restore();
Bitmap bm = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(),
bmp.getHeight(), mMatrix, true);
imageView.setImageBitmap(bm);
}
}
