android 获取屏幕宽高 和 获取控件坐标

一.获取屏幕宽高：

（1）.

WindowManager wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);
int width = wm.getDefaultDisplay().getWidth();
int height = wm.getDefaultDisplay().getHeight();

（2）.

WindowManager wm = this.getWindowManager();
int width = wm.getDefaultDisplay().getWidth();
int height = wm.getDefaultDisplay().getHeight();

二.获取控件的坐标:

int[] location = new int[2];
t.getLocationOnScreen(location);
int x = location[0];
int y = location[1];
System.out.println("x:"+x+"y:"+y);
System.out.println("图片各个角Left："+t.getLeft()+"Right："+t.getRight()+"Top："+t.getTop()+"Bottom："+t.getBottom());
