滑翔Gif图像

Question

我想在我的布局中加载动画gif并使用此代码

public class Main extends Activity {
ImageView iv;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    iv = (ImageView) findViewById(R.id.imageView1);
    Glide.with(Main.this)
            .load(R.drawable.gif)
            .asGif()
            .fitCenter()
            .into(iv);
}

但布局没有任何反应！ log cat：

我认为一类滑行没有加载！
