Aligning popup window near the button clicked

I have a custom popup window by a layout. I have to give a x,y coordinates to appear popup window after a_btn click. This can be different locations in different phones.
But I want to show the popup window always above and touching the the a_btn
How can I implement this.Help me
My code for showing the popup window :
a_btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
LayoutInflater lInflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View popup_view = lInflater.inflate(R.layout.popup_a, null);
final PopupWindow popup = new PopupWindow(popup_view,FrameLayout.LayoutParams.WRAP_CONTENT,FrameLayout.LayoutParams.WRAP_CONTENT,true);
popup.setFocusable(true);
popup.setBackgroundDrawable(new ColorDrawable());
popup.showAtLocation(relative, Gravity.NO_GRAVITY, coordinateTop, 100);
//popup.showAsDropDown(location_popup_view, 2, 2);
}
});

Use this code will help you
a_btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Rect r = locateView(v);
LayoutInflater lInflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View popup_view = lInflater.inflate(R.layout.popup_a, null);
final PopupWindow popup = new PopupWindow(popup_view,FrameLayout.LayoutParams.WRAP_CONTENT,FrameLayout.LayoutParams.WRAP_CONTENT,true);
popup.setFocusable(true);
popup.setBackgroundDrawable(new ColorDrawable());
popup.showAtLocation(layout, Gravity.TOP | Gravity.LEFT, r.right, r.bottom);
}
});
public static Rect locateView(View v) {
int[] loc_int = new int[2];
if (v == null)
return null;
try {
v.getLocationOnScreen(loc_int);
} catch (NullPointerException npe) {
return null;
}
Rect location = new Rect();
location.left = loc_int[0];
location.top = loc_int[1];
location.right = loc_int[0] + v.getWidth();
location.bottom = loc_int[1] + v.getHeight();
return location;
}

I used popup.showAsDropDown(a_btn,0,0);
instead of
popup.showAtLocation(relative, Gravity.NO_GRAVITY, coordinateTop, 100);
and gave xoff and yoff.
a_btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
LayoutInflater lInflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View popup_view = lInflater.inflate(R.layout.popup_a, null);
final PopupWindow popup = new PopupWindow(popup_view,200,200,true);
popup.setFocusable(true);
popup.setBackgroundDrawable(new ColorDrawable());
popup.showAsDropDown(a_btn,0,0);
}
});

PopWindow always show at last in ListView...!

I working on android PopupWindow. In this application I create 1 custom ListView. Now I want to show PopupWindow when user click on TextView of custom ListView.
My problem is :
PopupWindow always show at last TextView even if I click on first or other TextView . How can I resolve this.??
TextView of ListView.
holder.end.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int[] location = new int[2];
holder.end.getLocationOnScreen(location);
p = new Point();
p.x = location[0];
p.y = location[1];
if (p != null){
showPopup(context,p);
holder.popupText.setText(holder.end.getText().toString());
}
}
});
My popupWindow function.
private void showPopup(final Activity context, Point p) {
// Inflate the popup_layout.xml
LinearLayout viewGroup = (LinearLayout)context.findViewById(R.id.layoutPopup);
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = layoutInflater.inflate(R.layout.popup_layout, viewGroup);
holder.popupText = (TextView) layout.findViewById(R.id.showPopUp);
// Creating the PopupWindow
final PopupWindow popup = new PopupWindow(context);
popup.setContentView(layout);
popup.setWidth(LinearLayout.LayoutParams.WRAP_CONTENT);
popup.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT);
popup.setFocusable(true);
int OFFSET_X = 30;
int OFFSET_Y = 30;
popup.setBackgroundDrawable(new BitmapDrawable());
popup.showAtLocation(layout.findViewById(R.id.showPopUp), Gravity.NO_GRAVITY, p.x + OFFSET_X, p.y + OFFSET_Y);
}

Tray changing your click listener with this code. It should work.
holder.end.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int[] location = new int[2];
v.getLocationOnScreen(location);
p = new Point();
p.x = location[0];
p.y = location[1];
if (p != null){
showPopup(context,p);
holder.popupText.setText(holder.end.getText().toString());
}
}
});

How to center PopupWindow?

I created an Activity in which i add a button that throws a popup when is clicked. Here is the code of showPopup() method:
private void showPopup() {
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.popup_layout, (ViewGroup) findViewById(R.id.popup_element), false);
final PopupWindow pwindo = new PopupWindow(layout, LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT, true);
Button btnAgree = (Button) layout.findViewById(R.id.ok);
btnAgree.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
pwindo.dismiss();
}
});
pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);
}
}
I would center it both vertically and orizzontally. I tried several ways that i see here on SO but none worked. Why i always get the popup window at the top of the screen?

you can use setHorizontalOffset:
ListPopupWindow popupWindow = new ListPopupWindow(this);
// Position
popupWindow.setAnchorView(btn);
popupWindow.setPromptPosition (ListPopupWindow.POSITION_PROMPT_ABOVE);
popupWindow.setHorizontalOffset((btn.layoutParams.width - popupWindow.getWidth())/2);

this code will show perfect popup in center of you specific view
// click event of specific view
#Override
public void onClick(View v) {
super.onClick(v);
if (v == lin_filterActionbar) {
PopupWindow popupwindow_obj; // create object
popupwindow_obj = dialog_AllergiesSelect(RR_HomeActivity.this,lin_filterActionbar);
popupwindow_obj.showAsDropDown(lin_filterActionbar);
}
}
private PopupWindow dialog_AllergiesSelect(Context context,LinearLayout lin) {
final PopupWindow dialog_AllergiesSelect = new PopupWindow(this);
View v = View.inflate(context, R.layout.dialog_filter_actionbar, null);
dialog_AllergiesSelect.setContentView(v);
dialog_AllergiesSelect.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);
dialog_AllergiesSelect.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
dialog_AllergiesSelect.setFocusable(true);
// TextView lis_testSelection = (TextView) v.findViewById(R.id.dialogfilter_txt_filter);
// LinearLayout.LayoutParams lin_laLayoutParams = new LinearLayout.LayoutParams((int) (sunApplication.getDeviceWidth() - (sunApplication.getDeviceScale() * dialog_width_dvide_allerges_spinner_width)), (int) (sunApplication.getDeviceHeight() - (sunApplication.getDeviceScale() * dialog_width_dvide_allerges_height)));
// lis_testSelection.setLayoutParams(lin_laLayoutParams);
// Some offset to align the popup a bit to the right, and a bit down, relative to button's position.
int OFFSET_X = 0;
int OFFSET_Y = 0;
// Clear the default translucent background
dialog_AllergiesSelect.setBackgroundDrawable(new BitmapDrawable());
// Displaying the popup at the specified location, + offsets.
//dialog_AllergiesSelect.showAtLocation(v, Gravity.C, p.x + OFFSET_X, p.y + OFFSET_Y);
Rect location = locateView(lin);
dialog_AllergiesSelect.showAtLocation(v, Gravity.TOP|Gravity.CENTER, 0, location.bottom);
// Getting a reference to Close button, and close the popup when clicked.
return dialog_AllergiesSelect;
}
public static Rect locateView(View v)
{
int[] loc_int = new int[2];
if (v == null) return null;
try
{
v.getLocationOnScreen(loc_int);
} catch (NullPointerException npe)
{
//Happens when the view doesn't exist on screen anymore.
return null;
}
Rect location = new Rect();
location.left = loc_int[0];
location.top = loc_int[1];
location.right = location.left + v.getWidth();
location.bottom = location.top + v.getHeight();
return location;
}

How to change navigation of custom sliding menu

I am trying my custom sliding navigation. I know there are already lot's of tutorial or library is available but this is for my own purpose.
So basically i am trying to open sliding menu and it is opening left to right now i want to change it's direction from right to left. How can i do this.
Below is my code.
public class Profile extends Activity implements OnClickListener {
private int windowWidth;
boolean alreadyShowing = false;
private Animation mAnimation;
LayoutInflater mLayoutInflater;
private RelativeLayout mRelativeLayout;
ImageView sliding_menu;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.profile);
Display display = getWindowManager().getDefaultDisplay();
windowWidth = display.getWidth();
display.getHeight();
mLayoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
sliding_menu = (ImageView) findViewById(R.id.slidingMenu);
sliding_menu.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
if (!alreadyShowing) {
alreadyShowing = true;
openSlidingMenu();
}
}
});
}
private void openSlidingMenu() {
int width = (int) (windowWidth * 0.8f);
translateView((float) (width));
int height = LayoutParams.FILL_PARENT;
final View layout = mLayoutInflater.inflate(R.layout.settings,
(ViewGroup) findViewById(R.id.setting));
final PopupWindow optionsPopup = new PopupWindow(layout, width, height,
true);
optionsPopup.setBackgroundDrawable(new PaintDrawable());
optionsPopup.showAtLocation(layout, Gravity.NO_GRAVITY, 0, 0);
optionsPopup.setOnDismissListener(new PopupWindow.OnDismissListener() {
public void onDismiss() {
cleanUp();
translateView(0);
cleanUp();
alreadyShowing = false;
}
});
}
private void translateView(float right) {
mAnimation = new TranslateAnimation(0f, right, 0f, 0f);
mAnimation.setDuration(100);
mAnimation.setFillEnabled(true);
mAnimation.setFillAfter(true);
mRelativeLayout = (RelativeLayout) findViewById(R.id.profile);
mRelativeLayout.startAnimation(mAnimation);
mRelativeLayout.setVisibility(View.VISIBLE);
}
private void cleanUp() {
if (null != mRelativeLayout) {
mRelativeLayout.clearAnimation();
mRelativeLayout = null;
}
if (null != mAnimation) {
mAnimation.cancel();
mAnimation = null;
}
}
So basically you can see in above image that my menu is opening from left to right, how can i change it from right to left.
Thank you in advance.

I have solved this question, i have just changed gravity to right side of this below line and it is working now.
optionsPopup.showAtLocation(layout, Gravity.RIGHT, 0, 0);
So before change my code was something like this.
final PopupWindow optionsPopup = new PopupWindow(layout, width, height,true);
optionsPopup.setBackgroundDrawable(new PaintDrawable());
optionsPopup.showAtLocation(layout, Gravity.NO_GRAVITY, 0, 0);
and now it is like below
final PopupWindow optionsPopup = new PopupWindow(layout, width, height,true);
optionsPopup.setBackgroundDrawable(new PaintDrawable());
optionsPopup.showAtLocation(layout, Gravity.RIGHT, 0, 0);
Thank you all for helping me.

OnClick Event not detected on parentView in AChartEngine

I use the following code to draw GraphView on LinearLayout,whose parent is a RelativeLayout
the code for drawing GraphView on LinearLayout
mLinearView = (LinearLayout) findViewById(R.id.LinearView);//ChildLayout
mRelativeView = (RelativeLayout) findViewById(R.id.RelativeLay);//ParentLayout
YearXYGraph mYearGraph = new YearXYGraph();
final GraphicalView mGraphView = mYearGraph.execution(
MainActivity.this, mGirlHeightYearFirstGrade,
mGirlHeightYearSecondGrade,
mGirlHeightYearThirdGrade,
mGirlHeightYearFourthGrade,
mGirlHeightYearFifthGrade, mGirlWeightYearFirstGrade,
mGirlWeightYearSecondGrade, mGirlWeightYearThirdGrade,
mGirlWeightYearFourthGrade, mGirlWeightYearFifthGrade);
mLinearView.addView(mGraphView);
onclicking LinearLayout I'm Showing a popup,code follows
mGraphView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
double[] xy = mGraphView.toRealPoint(0);
p = new Point();
p.x = (int) xy[0];
p.y = (int) xy[1];
if (p != null){
showPopup(MainActivity.this, p);
}
}
});
Im also using onClick event on ParentLayout to get some coordinate
mRelativeView.setOnTouchListener(new RelativeLayout.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
System.out.println("in--");
p1 = new Point();
p1.x = (int) event.getX();
p1.y = (int) event.getY();
System.out.println("x--"+p1.x);
return false;
}
});
code for Showing popup
// The method that displays the popup.
private void showPopup(final Activity context, Point p) {
int popupWidth = 75;
int popupHeight = 40;
// Inflate the popup_layout.xml
LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.popup);
LayoutInflater layoutInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = layoutInflater.inflate(R.layout.popup_layout, viewGroup);
// Creating the PopupWindow
final PopupWindow popup = new PopupWindow(context);
popup.setContentView(layout);
popup.setWidth(popupWidth);
popup.setHeight(popupHeight);
popup.setFocusable(true);
Rect location = new Rect();
location.left =p1.x;
location.top = p1.y;
location.right = location.left + popup.getWidth();
location.bottom = location.top + popup.getHeight();
/* // Some offset to align the popup a bit to the right, and a bit down, relative to button's position.
int OFFSET_X = 30;
int OFFSET_Y = 30;*/
// Clear the default translucent background
popup.setBackgroundDrawable(new BitmapDrawable());
// Displaying the popup at the specified location, + offsets.
// popup.showAtLocation(layout, Gravity.TOP|Gravity.LEFT, location.left , location.bottom );
popup.showAtLocation(layout, Gravity.TOP|Gravity.LEFT, location.left , location.bottom );
// Getting a reference to Close button, and close the popup when clicked.
TextView firstView = (TextView) layout.findViewById(R.id.textView1);
firstView.setText(p.x + " , " +p.y);
firstView.setTextColor(Color.WHITE);
}
problem is onClickEvent not detected on ParentLayout,,Child Layout detects OnClick,please provide some suggestions
