Question

我在surfaceview中遇到了内存泄漏问题。

我定义了一个从surfaceview扩展的自定义视图MyView。

int Layout file 
<com.andoird.example.MyView
....
....
/>

和onCreate（）中的setContentView; 完成活动后。我得到下面的日志; 它显示Surface视图中存在内存泄漏。

我希望有人可以帮我解决这个问题。谢谢！

使用Android 4.2。

我找到了解决此问题的方法。你应该简单地打电话：

getHolder().getSurface().release();

来自活动onDestroy()

的控件

这样的事情：

class MyView {

    ...

    public void release() {
        getHolder().getSurface().release();
    }

    ...
}

class MyActivity extends Activity {

    ...

    @Override
    public void onDestroy() {
         super.onDestroy();
         mMyView.release();
    }

    ...

}
