如果图像不是很小(例如1.12 Mb 2560×1920),它会在更改屏幕方向上产生内存不足.我试过getDrawable.setCallback(null)但没有运气.

我哪里错了？

public class Fullscreen extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    System.gc();
    setContentView(R.layout.fullscreen);
    ImageView imageView = (ImageView) findViewById(R.id.full_screen_image);
    long imageId = 2;
    imageView.setImageURI(Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,"" + imageId));
    }
}
