view group

get view group, need to be improved.

public class HelloworldActivity extends Activity {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        FrameLayout decor = (FrameLayout)getWindow().getDecorView();        dumpViewGroup(decor);    }        LinkedList <View> gViewQueue = new LinkedList<View>();    int gLevel = 0;    public void dumpViewGroup(ViewGroup vg)    {        final int count = vg.getChildCount();        //Log.d(TAG, "lyftest count="+count);        for (int i = 0; i < count; i++) {            final View child = vg.getChildAt(i);            //if (child instanceof ViewGroup)            showViewName(child,gLevel);            gViewQueue.add(child);                    }        gLevel++;        showlevelmark(gLevel);        while(!gViewQueue.isEmpty())        {            View headview= gViewQueue.remove();            if(headview instanceof ViewGroup)            {                dumpViewGroup((ViewGroup)headview);            }        }    }    public void showlevelmark(int level)    {            }    public void showViewName(View v, int level)    {        Log.d("TAG", " :"+level+":view="+v+"(parent:"+v.getParent()+")");    }}

result:
