ViewTreeObserver和onWindowFocusChanged()根本不是必要的。

如果你膨胀的TextView作为布局和/或放一些内容在它和设置LayoutParams然后你可以使用getMeasuredHeight()和getMeasuredWidth()。

BUT you have to be careful with LinearLayouts (maybe also other ViewGroups). The issue there is, that you can get the width and height after onWindowFocusChanged() but if you try to add some views in it, then you can't get that information until everything have been drawn. I was trying to add multiple TextViews to LinearLayouts to mimic a FlowLayout (wrapping style) and so couldn't use Listeners. Once the process is started, it should continue synchronously. So in such case, you might want to keep the width in a variable to use it later, as during adding views to layout, you might need it.

我相信OP早就消失了，但如果这个答案能够帮助未来的搜索者，我想我应该发布一个我发现的解决方案。我已经在onCreate()方法中添加了以下代码:

编辑:07/05/11以包括来自注释的代码:

final TextView tv = (TextView)findViewById(R.id.image_test);
ViewTreeObserver vto = tv.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

    @Override
    public void onGlobalLayout() {
        LayerDrawable ld = (LayerDrawable)tv.getBackground();
        ld.setLayerInset(1, 0, tv.getHeight() / 2, 0, 0);
        ViewTreeObserver obs = tv.getViewTreeObserver();

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            obs.removeOnGlobalLayoutListener(this);
        } else {
            obs.removeGlobalOnLayoutListener(this);
        }
    }

});

首先，我得到一个最终引用我的TextView(访问在onGlobalLayout()方法)。接下来，我从我的TextView获得ViewTreeObserver，并添加一个OnGlobalLayoutListener，覆盖onGLobalLayout(似乎没有一个超类方法调用这里…)并添加我的代码，这需要知道视图的测量到这个侦听器。一切都如我所料，所以我希望这是能够帮助。

你可以使用OnResume()中调用的广播

例如:

int vh = 0;   
int vw = 0;

public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.maindemo);  //<- includes the grid called "board"

      registerReceiver(new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                TableLayout tl = (TableLayout) findViewById(R.id.board);  
                tl = (TableLayout) findViewById(R.id.board);
                vh = tl.getHeight();       
                vw = tl.getWidth();               
            }
      }, new IntentFilter("Test"));
}

protected void onResume() {
        super.onResume();

        Intent it = new Intent("Test");
        sendBroadcast(it);

}

你不能在OnCreate ()， onStart()，甚至在onResume()中获得视图的高度，原因是kcoppock响应

我只是添加一个替代解决方案，覆盖你的活动的onWindowFocusChanged方法，你将能够得到getHeight()的值，getWidth()从那里。

@Override
public void onWindowFocusChanged (boolean hasFocus) {
        // the height will be set at this point
        int height = myEverySoTallView.getMeasuredHeight(); 
}

我猜这就是你需要看的:使用视图的onSizeChanged()。下面是一个关于如何使用onSizeChanged()来动态获取布局或视图的高度和宽度的扩展代码片段http://syedrakibalhasan.blogspot.com/2011/02/how-to-get-width-and-height-dimensions.html

简单回答:这对我来说没有问题。 似乎关键是要确保视图在getHeight等之前有焦点。通过使用hasFocus()方法来实现这一点，然后按此顺序使用getHeight()方法。只需要3行代码。

ImageButton myImageButton1 =（ImageButton）findViewById（R.id.imageButton1）; myImageButton1.hasFocus（）;

int myButtonHeight = myImageButton1.getHeight();

日志。d("Button Height: "， ""+myButtonHeight);//不需要

希望能有所帮助。
