获取坐标。。。好吧，之前在onCreate里getButtom一直都是0，纠结的很，转一遍让我解决问题的文章，谢谢原作者。

int[] location = new int[2] ; view.getLocationInWindow(location); //获取在当前窗口内的绝对坐标 view.getLocationOnScreen(location);//获取在整个屏幕内的绝对坐标 location [0]--->x坐标,location [1]--->y坐标 如果在Activity的OnCreate()事件输出那些参数，是全为0，要等UI控件都加载完了才能获取到这些。 private ViewFlipper flipper; @Override public void onCreate(Bundle savedInstanceState) {
    Log.i("demo", "onCreate"); super.onCreate(savedInstanceState); setContentView(R.layout.main); flipper = (ViewFlipper)findViewById(R.id.flipper); Log.d("demo", "left:" + flipper.getLeft()); Log.d("demo", "right:" + flipper.getRight()); Log.d("demo", "Top:" + flipper.getTop()); Log.d("demo", "Bottom:" + flipper.getBottom()); Button btn = (Button)findViewById(R.id.button2); btn.setOnClickListener(new OnClickListener(){
    public void onClick(View v) {
    Log.i("demo", "onClick"); Log.d("demo", "left:" + flipper.getLeft()); Log.d("demo", "right:" + flipper.getRight()); Log.d("demo", "Top:" + flipper.getTop()); Log.d("demo", "Bottom:" + flipper.getBottom()); } }); }
