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

高度和宽度为零，因为在你请求它的高度和宽度时，视图还没有被创建。最简单的解决方法是

view.post(new Runnable() {
    @Override
    public void run() {
        view.getHeight(); //height is ready
        view.getWidth(); //width is ready
    }
});

与其他方法相比，这种方法是很好的，因为它是短而脆。

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(); 
}

正如F.X.提到的，你可以使用OnLayoutChangeListener来跟踪你想要跟踪的视图

view.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
    @Override
    public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
        // Make changes
    }
});

如果只需要初始布局，可以在回调中删除侦听器。

                vh = tl.getHeight();       
                vw = tl.getWidth();               
            }
      }, new IntentFilter("Test"));
}

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

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