android 获取坐标

 

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;@Overridepublic 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());}});}
