求大神解答，解决handler内存溢出用了弱引用，我这种写法为什么还会警告，

Question

public class MainActivity extends AppCompatActivity {

private static class MyHandler extends Handler{
    WeakReference<AppCompatActivity> mactivity;
    public MyHandler(AppCompatActivity activity)
    {
        mactivity=new WeakReference<AppCompatActivity>(activity);
    }
}
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    final MyHandler handler=new MyHandler(this){
        @Override
    public void handleMessage(Message msg)
        {

        }
    };
}

}
