getLocationOnScreen 计算该视图在全局坐标系中的x,y值,(注意这个值是要从屏幕顶端算起,也就是包括了通知栏的高度)//获取在当前屏幕内的绝对坐标
getLocationInWindow 计算该视图在它所在的widnow的坐标x,y值,//获取在整个窗口内的绝对坐标
getLeft , getTop, getBottom, getRight, 这一组是获取相对在它父亲里的坐标
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。

在代码中,我想根据itemVIew的坐标来绘制一个新的ImageView控件,但如果整个界面没有父容器时,拿到的坐标是可以直接使用的,而当前界面上有父容器,或者有与其平行的界面时,坐标是有偏移的,所以我加上了有些判断处理,根据不同的布局,适当的调整下坐标的偏移量
if(GlobalData.loginState()){
params=newAbsoluteLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT, location[0]-15, location[1]-95);
}else{
params=newAbsoluteLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT, location[0]-15, location[1]-25);
}
