I have a NavigationView with menu.
When any menuitem is long pressed, I inflate a popup which gives the user various options/buttons. Each button has an event handler.
I need those handlers to know which menuitem originally triggered the popup.
What I am missing is the knowledge of how to pass that identity along the flow of objects.
In the posted code, the menuitem is longclicked, I pass menutem as a view to the popup constructor.
Yet no idea how to then pass it to the popup Button's event handler.
I am considering as an alternative, simply setting a variable with the id when the longpress occurs, and then reading that variable back again in the final handler.... but that does feel like a cheat and would require managing to ensure synchronising with events.
#Override
public boolean onLongClick(View v) {
pop(v);
return true;
}
public void pop(View v){
LayoutInflater layoutInflater =
(LayoutInflater)getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup, null);
final PopupWindow popupWindow = new PopupWindow(
popupView,
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
Button btnDismiss = (Button)popupView.findViewById(R.id.dismiss);
btnDismiss.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View vw) {
Toast.makeText(getApplicationContext(), "id of menuitem here", Toast.LENGTH_SHORT).show();
popupWindow.dismiss();
}
});
popupWindow.showAsDropDown(v, 50, -30);
}
If I got your question right, you just want to pass the id of menuitem tapped on to pop method and later display that value in Toast.
In that case considering you can cast the id value into string, you can use setTag() and getTag():
#Override
public boolean onLongClick(View v)
{
v.setTag(place the id of menuitem tapped here);
pop(v);
return true;
}
public void pop(View v)
{
LayoutInflater layoutInflater =
(LayoutInflater)getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup, null);
final PopupWindow popupWindow = new PopupWindow(
popupView,
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
Button btnDismiss = (Button)popupView.findViewById(R.id.dismiss);
btnDismiss.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View vw) {
Toast.makeText(getApplicationContext(), String.valueOf(v.getTag()), Toast.LENGTH_SHORT).show();
popupWindow.dismiss();
}
});
popupWindow.showAsDropDown(v, 50, -30);
}

my problem by displaying a popup is that the view back is not blocked , I need block and obscure the view while the popup this over , I need the view can not be clicked , only the popup
My Popup:
View popupView;
PopupWindow popupWindow;
popupView = layoutInflater.inflate(R.layout.popup_ver_noconf_submateria_urgente, null);
popupWindow = new PopupWindow(popupView, RadioGroup.LayoutParams.WRAP_CONTENT, RadioGroup.LayoutParams.WRAP_CONTENT);
popupWindow.showAtLocation(v, Gravity.CENTER, 0, 0);
aceptar = (Button) popupView.findViewById(R.id.acept);
aceptar.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
sub.activity.startActivity(new Intent(sub.activity, VerNoConformidadesSubmateria.class));
popupWindow.dismiss();
releaseLayout();
}
});
PD: Sorry for the bad english
I have two Linear Layouts in single activity .
I want to display custom popups on each of them when clicked.
When I click on first layout, popup apperas,then on clicking on 2nd layout ,both popups are displayed. how can i have only single popup displayed at a time?
this is my code
workLinearLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
LayoutInflater layoutInflater=
(LayoutInflater)getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate
(R.layout.activity_your_places__work__popup, null);
updateTextView = (TextView)
popupView.findViewById(R.id.UpdateTextView);
updateTextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(Your_Places2Activity.this,
UpdateWorkAddressActivity.class);
startActivity(i);
}
});
deleteTextView = (TextView)
popupView.findViewById(R.id.DeleteTextView);
deleteTextView.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v) {
//code to delete address
}
});
popupWindowWork = new PopupWindow(
popupView,
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
//dismiss other popup if is showing
if(popupWindowHome.isShowing())
{
popupWindowHome.dismiss();}
//display popup
popupWindowWork.showAsDropDown(workLinearLayout, 0, -70);
}
});
i have done same thing on other linear layout
popupWindowWork = new PopupWindow(
popupView,
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
if(popupWindowHome.isShowing())
{
popupWindowHome.dismiss();
}
in this line, you are dismissing the popupWindowHome dialog if popupWindowHome is showing, with popupWindowHome being the NEW dialog. Move the if statement before the constructor call.
if(popupWindowHome != null && popupWindowHome.isShowing())
{
popupWindowHome.dismiss();
}
popupWindowWork = new PopupWindow(
popupView,
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
I'm implementing a popup in fragment Tab3Fragment and would like to keep the popup code in,
public void showPopup(View anchorView){
}
and minimized elsewhere in the Tab3Fragment as much as possible to keep things tidy.
Currently showPopup looks something like this,
public void showPopup(View anchorView) {
Button btnDismiss, btnFirstRecord, btnPreviousRecord, btnNextRecord, btnLastRecord;
LayoutInflater layoutInflater = (LayoutInflater)getActivity().getSystemServi (Context.LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup_layout, null);
final PopupWindow popupWindow = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
TextView tv = (TextView)popupView.findViewById(R.id.tv);
tv.setText("Blah, blah, blah");
btnDismiss = (Button)popupView.findViewById(R.id.btnDismissxml);
btnFirstRecord = (Button)popupView.findViewById(R.id.btnFirstRecordxml);
btnPreviousRecord = (Button)popupView.findViewById(R.id.btnPreviousRecordxml);
btnNextRecord = (Button)popupView.findViewById(R.id.btnNextRecordxml);
btnLastRecord = (Button)popupView.findViewById(R.id.btnLastRecordxml);
popupWindow.setFocusable(true);
int location[] = new int[2];
anchorView.getLocationOnScreen(location);
popupWindow.showAtLocation(anchorView, Gravity.CENTER, 0, 0);
}
}
QUESTION: Is there any way to implement an onClick method case-switch statement inside of showPopup that would handle this? Perhaps something like,
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnFirstRecordxml:
//firstRecord(v);
break;
case R.id.btnPreviousRecordxml:
//previousRecord(v);
break;
case R.id.btnNextRecordxml:
//nextRecord(v);
break;
case R.id.btnLastRecordxml:
//lastRecord(v);
break;
case R.id.btnDismissxml:
//closePopup(v);
break;
}}
Other solutions such as putting onClick in popup_layout.xml thusly,
<Button
android:id="#+id/btnFirstRecordxml"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/pszFirstRecordButton"
android:onClick="Tab3Fragment.firstRecord"/>
to handle button clicks would be highly appreciated. Thanks in advance...
Update, 23 Nov 2014.
Here is a solution that does work for more than one button's code in showPopup(). I'll have several buttons in the popup....
private void showPopup(){
LayoutInflater layoutInflater = (LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup_layout, null);
Button btnDismiss=(Button)popupView.findViewById(R.id.btnDismissxml);
Button btnSaveRecord=(Button)popupView.findViewById(R.id.btnSaveRecordxml);
final PopupWindow popupWindow=new PopupWindow(popupView,480,500,true);
popupWindow.showAtLocation(popupView, Gravity.CENTER, 0, 40);
//first button
btnSaveRecord.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
saveRecord();
}
});
//second button
btnDismiss.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
popupWindow.dismiss();
}
});
}
Any way to insert a case-switch structure to allow other button code in showPopup()? This would avoid creating separate onClickListener-onClicks for each button as shown above.
Modify the xml like this, use android:onClick="ClickEvent" this formet in all the button
<Button
android:id="#+id/btnFirstRecordxml"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/pszFirstRecordButton"
android:onClick="ClickEvent"/>
<Button
android:id="#+id/btnPreviousRecordxml"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/pszPreviousRecordButton"
android:onClick="ClickEvent"/>
use the click funcationality like this,
public void clickEvent(View v)
{
switch (v.getId()) {
case R.id.btnFirstRecordxml:
//firstRecord(v);
break;
case R.id.btnPreviousRecordxml:
//previousRecord(v);
break;
case R.id.btnNextRecordxml:
//nextRecord(v);
break;
case R.id.btnLastRecordxml:
//lastRecord(v);
break;
case R.id.btnDismissxml:
//closePopup(v);
break;
}
}
Or try this,
btn.setOnClickListener(btnaction); set like this listener for all buttons,
OnClickListener btnaction = new OnClickListener() {
#Override
public void onClick(View v) {
//use the switch conditons...
}
};
btn1.setOnClickListener(btnaction);
btn2.setOnClickListener(btnaction);
public void showPopup(View anchorView) {
Button btnDismiss, btnFirstRecord, btnPreviousRecord, btnNextRecord, btnLastRecord;
LayoutInflater layoutInflater = (LayoutInflater)getActivity().getSystemServi (Context.LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup_layout, null);
final PopupWindow popupWindow = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
TextView tv = (TextView)popupView.findViewById(R.id.tv);
tv.setText("Blah, blah, blah");
btnDismiss = (Button)popupView.findViewById(R.id.btnDismissxml);
btnFirstRecord = (Button)popupView.findViewById(R.id.btnFirstRecordxml);
btnPreviousRecord = (Button)popupView.findViewById(R.id.btnPreviousRecordxml);
btnNextRecord = (Button)popupView.findViewById(R.id.btnNextRecordxml);
btnLastRecord = (Button)popupView.findViewById(R.id.btnLastRecordxml);
btnFirstRecord.setOnClickListener(new Listener());
btnPreviousRecord.setOnClickListener(new Listener());
btnNextRecord .setOnClickListener(new Listener());
btnLastRecord .setOnClickListener(new Listener());
popupWindow.setFocusable(true);
int location[] = new int[2];
anchorView.getLocationOnScreen(location);
popupWindow.showAtLocation(anchorView, Gravity.CENTER, 0, 0);
}
}
Class Listener implements OnClickListener
{
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnFirstRecordxml:
//firstRecord(v);
break;
case R.id.btnPreviousRecordxml:
//previousRecord(v);
break;
case R.id.btnNextRecordxml:
//nextRecord(v);
break;
case R.id.btnLastRecordxml:
//lastRecord(v);
break;
case R.id.btnDismissxml:
//closePopup(v);
break;
}
}
}
I have 3 Image buttons and on press they each have a Popup window that opens up. The issue is when i click on button 1, there is a popup, if I DONT dismiss that popup but click on Button 2 instead, the pop-up for Button 1 and Button 2 appear.
How do i dismiss any open Pop-up's when a new button is pressed?
Here is my code
final ImageButton rredButton=(ImageButton)findViewById(R.id.RredButton);
rredButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
LayoutInflater layoutInflater
= (LayoutInflater)getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popupright, null);
final PopupWindow popupWindow = new PopupWindow(
popupView,
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
Button btnNxtScr = (Button)popupView.findViewById(R.id.nextscreen);
btnNxtScr.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View v) {
Intent myintent1 = new Intent(colorActivity.this,colorBlueActivity.class);
startActivity(myintent1);
}
});
popupWindow.showAsDropDown(rredButton, 1, -1);
}});
And here is the other button (with a similar popup method)
final ImageButton ryellowButton=(ImageButton)findViewById(R.id.RyellowButton);
ryellowButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
createWrongPop(arg0);
}});
To do this you'll need to save a reference to the PopupWindow in your class when the popup is shown, and clear it out when the popup is dismissed. Then, if you click the second button, you can check to see if the popup is available, and if it is, either call .dismiss() on it and create a new one, or modify it's contents.
To create a simple working PopupWindow, we need to do the following:
popup_example.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:padding="10dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dip"
android:text="Test Pop-Up" />
</LinearLayout>
Java code
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
PopupWindow pw = new PopupWindow(inflater.inflate(R.layout.popup_example, null, false),100,100, true);
pw.showAtLocation(this.findViewById(R.id.main), Gravity.CENTER, 0, 0);
My requirement is that I need a
<TEXTVIEW android:layout_height="wrap_content" android:layout_width="fill_parent" />
and a
<BUTTON android:id="#+id/end_data_send_button" android:text="Cancel"/>
in my popup_example.xml. How can I handle these two components in my Java code?
How to make a simple Android popup window
This is a fuller example. It is a supplemental answer that deals with creating a popup window in general and not necessarily the specific details of the OP's problem. (The OP asks for a cancel button, but this is not necessary because the user can click anywhere on the screen to cancel it.) It will look like the following image.
Make a layout for the popup window
Add a layout file to res/layout that defines what the popup window will look like.
popup_window.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#62def8">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_margin="30dp"
android:textSize="22sp"
android:text="This is a popup window."/>
</RelativeLayout>
Inflate and show the popup window
Here is the code for the main activity of our example. Whenever the button is clicked, the popup window is inflated and shown over the activity. Touching anywhere on the screen dismisses the popup window.
MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onButtonShowPopupWindowClick(View view) {
// inflate the layout of the popup window
LayoutInflater inflater = (LayoutInflater)
getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = inflater.inflate(R.layout.popup_window, null);
// create the popup window
int width = LinearLayout.LayoutParams.WRAP_CONTENT;
int height = LinearLayout.LayoutParams.WRAP_CONTENT;
boolean focusable = true; // lets taps outside the popup also dismiss it
final PopupWindow popupWindow = new PopupWindow(popupView, width, height, focusable);
// show the popup window
// which view you pass in doesn't matter, it is only used for the window tolken
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
// dismiss the popup window when touched
popupView.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
popupWindow.dismiss();
return true;
}
});
}
}
That's it. You're finished.
Going on
Check out how gravity values effect PopupWindow.
You can also add a shadow.

PopupWindow documentation
How To Create Pop Up Window In Android (YouTube video)
Android Popup Window Example
Here, I am giving you a demo example. See this and customize it according to your need.
public class ShowPopUp extends Activity {
PopupWindow popUp;
boolean click = true;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
popUp = new PopupWindow(this);
LinearLayout layout = new LinearLayout(this);
LinearLayout mainLayout = new LinearLayout(this);
TextView tv = new TextView(this);
Button but = new Button(this);
but.setText("Click Me");
but.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (click) {
popUp.showAtLocation(layout, Gravity.BOTTOM, 10, 10);
popUp.update(50, 50, 300, 80);
click = false;
} else {
popUp.dismiss();
click = true;
}
}
});
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
layout.setOrientation(LinearLayout.VERTICAL);
tv.setText("Hi this is a sample text for popup window");
layout.addView(tv, params);
popUp.setContentView(layout);
// popUp.showAtLocation(layout, Gravity.BOTTOM, 10, 10);
mainLayout.addView(but, params);
setContentView(mainLayout);
}
}
Hope this will solve your issue.
are you done with the layout inflating? maybe you can try this!!
View myPoppyView = pw.getContentView();
Button myBelovedButton = (Button)myPoppyView.findViewById(R.id.my_beloved_button);
//do something with my beloved button? :p
I construct my own class, and then call it from my activity, overriding small methods like showAtLocation. I've found its easier when I have 4 to 5 popups in my activity to do this.
public class ToggleValues implements OnClickListener{
private View pView;
private LayoutInflater inflater;
private PopupWindow pop;
private Button one, two, three, four, five, six, seven, eight, nine, blank;
private ImageButton eraser;
private int selected = 1;
private Animation appear;
public ToggleValues(int id, Context c, int screenHeight){
inflater = (LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
pop = new PopupWindow(inflater.inflate(id, null, false), 265, (int)(screenHeight * 0.45), true);
pop.setBackgroundDrawable(c.getResources().getDrawable(R.drawable.alpha_0));
pView = pop.getContentView();
appear = AnimationUtils.loadAnimation(c, R.anim.appear);
one = (Button) pView.findViewById(R.id.one);
one.setOnClickListener(this);
two = (Button) pView.findViewById(R.id.two);
two.setOnClickListener(this);
three = (Button) pView.findViewById(R.id.three);
three.setOnClickListener(this);
four = (Button) pView.findViewById(R.id.four);
four.setOnClickListener(this);
five = (Button) pView.findViewById(R.id.five);
five.setOnClickListener(this);
six = (Button) pView.findViewById(R.id.six);
six.setOnClickListener(this);
seven = (Button) pView.findViewById(R.id.seven);
seven.setOnClickListener(this);
eight = (Button) pView.findViewById(R.id.eight);
eight.setOnClickListener(this);
nine = (Button) pView.findViewById(R.id.nine);
nine.setOnClickListener(this);
blank = (Button) pView.findViewById(R.id.blank_Selection);
blank.setOnClickListener(this);
eraser = (ImageButton) pView.findViewById(R.id.eraser);
eraser.setOnClickListener(this);
}
public void showAtLocation(View v) {
pop.showAtLocation(v, Gravity.BOTTOM | Gravity.LEFT, 40, 40);
pView.startAnimation(appear);
}
public void dismiss(){
pop.dismiss();
}
public boolean isShowing() {
if(pop.isShowing()){
return true;
}else{
return false;
}
}
public int getSelected(){
return selected;
}
public void onClick(View arg0) {
if(arg0 == one){
Sudo.setToggleNum(1);
}else if(arg0 == two){
Sudo.setToggleNum(2);
}else if(arg0 == three){
Sudo.setToggleNum(3);
}else if(arg0 == four){
Sudo.setToggleNum(4);
}else if(arg0 == five){
Sudo.setToggleNum(5);
}else if(arg0 == six){
Sudo.setToggleNum(6);
}else if(arg0 == seven){
Sudo.setToggleNum(7);
}else if(arg0 == eight){
Sudo.setToggleNum(8);
}else if(arg0 == nine){
Sudo.setToggleNum(9);
}else if(arg0 == blank){
Sudo.setToggleNum(0);
}else if(arg0 == eraser){
Sudo.setToggleNum(-1);
}
this.dismiss();
}
}
Button endDataSendButton = (Button)findViewById(R.id.end_data_send_button);
Similarly you can get the text view by adding a id to it.
LayoutInflater inflater = (LayoutInflater) SettingActivity.this.getSystemService(SettingActivity.LAYOUT_INFLATER_SERVICE);
PopupWindow pw = new PopupWindow(inflater.inflate(R.layout.gd_quick_action_slide_fontsize, null),LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT, true);
pw.showAtLocation(SettingActivity.this.findViewById(R.id.setting_fontsize), Gravity.CENTER, 0, 0);
View v= pw.getContentView();
TextView tv=v.findViewById(R.id.....);
This an example from my code how to address a widget(button) in popupwindow
View v=LayoutInflater.from(getContext()).inflate(R.layout.popupwindow, null, false);
final PopupWindow pw = new PopupWindow(v,500,500, true);
final Button button = rootView.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pw.showAtLocation(rootView.findViewById(R.id.constraintLayout), Gravity.CENTER, 0, 0);
}
});
final Button popup_btn=v.findViewById(R.id.popupbutton);
popup_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
popup_btn.setBackgroundColor(Color.RED);
}
});
