android.graphics.Camera图片绕X,Y,Z轴旋转

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);
    }
}
