如何修复SurfaceView内存泄漏

Question

我遇到了Surfaceview中的内存泄漏问题。

我定义了一个自定义视图MyView，它从surfaceview扩展而来。

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

和setContentView in onCreate（）;活动完成后，请拨打 。 我得到下面的日志; 它显示表面视图中有内存泄漏。

我希望有人能帮我解决这个问题。谢谢！

使用Android 4.2。

我发现这个问题的解决方法。 你应该简单的调用：

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

从活动的 onDestroy()

像这样的东西你的控制

：

class MyView { 

    ... 

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

    ... 
} 

class MyActivity extends Activity { 

    ... 

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

    ... 

}
