android – SurfaceView onMeasure()没有通过调用setMeasuredDimension()来设置测量的维度

概述我有一个SurfaceView.我只是从另一个Thread手动绘制它. 它运行得很好.但是在平均运行10-20分钟后,我得到了这个例外： 01-14 08:51:25.000 3740-3740/com.myPackage E/AndroidRuntime﹕ FATAL EXCEPTION: main java.lang.IllegalStateException: onMeasur 我有一个SurfaceVIEw.我只是从另一个Thread手动绘制它.

AndroID documention说：
测量视图及其内容以确定测量的宽度和测量的高度.此方法由measure(int,int)调用,并应由子类覆盖,以提供对其内容的准确有效的测量.

我认为谷歌的原始实现是这样的：

@OverrIDe    protected voID More ...onMeasure(int wIDthMeasureSpec,int heightmeasureSpec) {        int wIDth = getDefaultSize(mRequesteDWIDth,wIDthMeasureSpec);        int height = getDefaultSize(mRequestedHeight,heightmeasureSpec);        setMeasuredDimension(wIDth,height);    }

我不知道我应该在这里实施什么.

我认为表面视图的大小永远不会改变.

注意：
我的SurfaceVIEw包含在relativeLayout中.
该例外由一个孩子调用,但它是一个视图(异常中的第3行)

如果你知道我怎么能解决这个烦人的BUG,请帮助我.

编辑：
在Activity的onCreate中,我从代码中设置了视图(扩展形式为SurfaceVIEw)的大小

Answear评论：
这是我为所需大小设置一些公共字段的方法：

Parameters.initialize(getResources().getdisplayMetrics().wIDthPixels,getResources().getdisplayMetrics().heightPixels);

Parameters.initialize：

public static voID initialize(int screenWIDth,int screenHeight){    FIELD_WIDTH = screenWIDth;    FIELD_HEIGHT = (int)(0.92f * screenHeight);}

MyVIEw是用xml编写的.
然后我在上面设置了一些东西：

public class MyVIEwManager {    protected MyVIEw mMyVIEw;    public FIEldPainterComp(MainActivity activity) {        super(activity);        initialize();    }    private voID initialize(){        mMyVIEw= (MyVIEw) activity.findVIEwByID(R.ID.vMyVIEw);        mMyVIEw.getLayoutParams().height = Parameters.FIELD_HEIGHT;        mMyVIEw.getLayoutParams().wIDth = Parameters.FIELD_WIDTH;    }}

整个过程在一开始就发生了.

androID:screenorIEntation="landscape"

屏幕永远不会变暗.游戏正在运行,只是异常即将到来.
我应该在某处调用措施吗？
我不明白为什么很久以后就会开心呢

必须与此相关的其他一些例外：

GAV是谷歌分析的东西.

我发布了另一个关于ANR：ANR with 3 threads – using locks的问题

解决方法

setMeasuredDimension()

必须在onMeasure()方法内部调用.我有一个类似的问题,逻辑没有达到setMeasuredDimension().我解决了强制调用setMeasuredDimension()的问题,无论if / else语句在它之前是什么.
