本文介绍了获取错误的X和Y座标机器人的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
保护无效setQuickActionListener（查看按钮）{ 浮密度= mActivity.getResources（）getDisplayMetrics（）密度。
WindowManager.LayoutParams wmlp = mActivity.getWindow（）的getAttributes（）。
button.getLocationInWindow（位置）;
Toast.makeText（mActivity，L1位置+ [0] +12+位置[1]，Toast.LENGTH_LONG）.show（）;
wmlp.gravity = Gravity.TOP | Gravity.LEFT;
wmlp.x =位置[0] +（int）的（（（button.getWidth（）/ 2）+ button.getHeight（）/ 4）/密度）;
wmlp.y =位置[1] +（int）的（（button.getHeight（） - 60）/密度）;
mQuickAction.show（按钮，（INT）wmlp.x，（INT）wmlp.y）;}
在这里我使用得到x和y的值的ImageButton的点击监听器来显示快速行动的意见的方法和这个code作秀方法采取行动的看法。

解决方案
每个视图对象/子类可以访问哪些做的正是这个方法。
View.getTop（）; //这个视图相对于其父的顶部位置。
View.getLeft（）; //这个视图相对于其父的左侧位置。
View.getRight（）; //这个视图相对于其父的右侧位置。
View.getBottom（）; //这个视图相对于其父的下方位置。
您必须确保查看之前已经调用任何这些方法显示出来，否则，你会得到 0 或者最坏的NPE。
记住，相对于视图的父这些返回岗位。如果你想在实际绝对视图的位置，那么你将需要使用方法（S）：
View.getLocationInWindow（）; //计算这种观点在其窗口的坐标。
要么
View.getLocationOnScreen（）; //计算在屏幕上这种观点的坐标。
有没有必要推倒重来。进一步的信息可以在这里找到： http://developer.android.com/reference/安卓/浏览/ View.html
protected void setQuickActionListener(View button) {
float density = mActivity.getResources().getDisplayMetrics().density;
WindowManager.LayoutParams wmlp = mActivity.getWindow().getAttributes();
button.getLocationInWindow(location);
Toast.makeText(mActivity, " l1 " + location[0] + " l2 " + location[1],Toast.LENGTH_LONG).show();
wmlp.gravity = Gravity.TOP | Gravity.LEFT;
wmlp.x = location[0]+ (int) (((button.getWidth() / 2) + button.getHeight() / 4) / density);
wmlp.y = location[1] + (int) ((button.getHeight() - 60) / density);
mQuickAction.show(button, (int) wmlp.x, (int) wmlp.y);
}
here the method i am using to get x y values for an ImageButton click listener to show quick action views and this the code for show method for action views.
public void show(View anchor, int xPos, int yPos) {
preShow();
mDidAction = false;
int[] location = new int[2];
anchor.getLocationOnScreen(location);
Rect anchorRect = new Rect(location[0], location[1], location[0] + anchor.getWidth(), location[1]
+ anchor.getHeight());
mRootView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
mRootView.measure(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
int rootHeight = mRootView.getMeasuredHeight();
int rootWidth = mRootView.getMeasuredWidth();
if (rootWidth == 0) {
rootWidth = mRootView.getMeasuredWidth();
}
int screenWidth = mWindowManager.getDefaultDisplay().getWidth();
int screenHeight = mWindowManager.getDefaultDisplay().getHeight();
arrowPos = anchorRect.centerX()-xPos;
int dytop = anchorRect.top;
int dybottom = screenHeight/4;
boolean onTop = (dytop > dybottom) ? true : false;
LinearLayout.LayoutParams rlpms;
// xPos > (screenWidth - 100
int dyleft = xPos;
int dyright = screenWidth - screenWidth/10;
boolean onRight = (dyleft > dyright) ? true : false;
if (onRight) {
if(onTop){
yPos = anchorRect.top - rootHeight/3;
im1 =(ImageView) mRootView.findViewById(R.id.arrow_down);
rlpms=new LinearLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);
android.widget.LinearLayout.LayoutParams lp = (android.widget.LinearLayout.LayoutParams) im1.getLayoutParams();
lp.setMargins(0,rootHeight/3,0 ,0);
im1.setLayoutParams(lp);
Log.d("ddsaf", ""+onTop);
}
else
{
im1 =(ImageView) mRootView.findViewById(R.id.arrow_down);
rlpms=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);
android.widget.LinearLayout.LayoutParams lp = (android.widget.LinearLayout.LayoutParams) im1.getLayoutParams();
lp.setMargins(0,5,0 ,0);
im1.setLayoutParams(lp);
//Log.d("ddsaf", ""+onTop);
}
xPos = anchorRect.left - rootWidth;
} else {
if(onTop){
yPos = anchorRect.top - rootHeight/3;
im1 =(ImageView) mRootView.findViewById(R.id.arrow_up);

Log.d("ddsaf", ""+anchorRect.left);
showArrow(((onRight) ? R.id.arrow_down : R.id.arrow_up), arrowPos);
setAnimationStyle(screenWidth, anchorRect.centerX(), onRight);
mWindow.showAtLocation(anchor, Gravity.NO_GRAVITY, xPos, yPos);}
problem is i am getting quick action views at wrong postions ie at 0,0 once in while on infalted layout any idea why this happens below is where it has been infalted to with *

解决方案
Each View object/subclass has access to methods which do exactly this.
View.getTop(); // Top position of this view relative to its parent.
View.getLeft(); // Left position of this view relative to its parent.
View.getRight(); // Right position of this view relative to its parent.
View.getBottom(); // Bottom position of this view relative to its parent.
You have to ensure that the View has been displayed prior to calling any of these methods, otherwise you'll get 0 or at worst an NPE.
Bear in mind, these return positions relative to a View's parent. If you want the actual absolute position of the View, then you will need to use the method(s):
View.getLocationInWindow(); // Computes the coordinates of this view in its window.
or
View.getLocationOnScreen(); // Computes the coordinates of this view on the screen.
There is no need to reinvent the wheel. Further information can be found here: http://developer.android.com/reference/android/view/View.html
