I need to dismiss system alert window on back pressed and home button event.I have tried with onKeyEvent but in vain. As we can't capture the back pressed event in a service, how to achieve this?
Since it's a service that hosting an overlay window, It's a bit tricky solution but it is possible.
You should handle these 2 cases separately (overriding home button press, and back button press).
1. Overriding home button press:
Create this HomeWatcher class which contains a BroadcastReceiver that will notify when home button was pressed. Register this receiver only when your window comes up.
Android: associate a method to home button of smartphone
Inside your service onCreate method use this:
HomeWatcher mHomeWatcher = new HomeWatcher(this);
mHomeWatcher.setOnHomePressedListener(new OnHomePressedListener() {
#Override
public void onHomePressed() {
yourWindow.hide() //means: windowManager.removeView(view);
}
#Override
public void onHomeLongPressed() {
}
});
mHomeWatcher.startWatch();
2. Overriding back button press:
The idea is creating an empty layout as a data member of your window class,
and attach your view to it (even if its an inflated XML layout).
For example, this is gonna be your window class:
public class MyWindow
{
private WindowManager windowManager;
private WindowManager.LayoutParams params;
private View view;
// Add this empty layout:
private MyLayout myLayout;
public MyWindow()
{
windowManager = (WindowManager) context.getSystemService(context.WINDOW_SERVICE);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.your_original_window_layout, null);
// Add your original view to the new empty layout:
myLayout = new MyLayout(this);
myLayout.addView(view, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
}
// And show this layout instead of your original view:
public void show()
{
windowManager.addView(myLayout, params);
}
public void hide()
{
windowManager.removeView(myLayout);
}
}
And now create the MyLayout class to override the back button press:
public class MyLayout extends LinearLayout
{
private MyWindow myWindow;
public MyLayout(MyWindow myWindow)
{
super(myWindow.context);
this.myWindow = myWindow;
}
#Override public boolean dispatchKeyEvent(KeyEvent event)
{
if (event.getKeyCode() == KeyEvent.KEYCODE_BACK)
{
if (event.getAction() == KeyEvent.ACTION_DOWN && event.getRepeatCount() == 0)
{
getKeyDispatcherState().startTracking(event, this);
return true;
}
else if (event.getAction() == KeyEvent.ACTION_UP)
{
getKeyDispatcherState().handleUpEvent(event);
if (event.isTracking() && !event.isCanceled())
{
// dismiss your window:
myWindow.hide();
return true;
}
}
}
return super.dispatchKeyEvent(event);
}
}
I know it's a bit complicated as I said since it's a system alert window hosted by a service, BUT it's working. I have the same issue as well and it has been solved exactly like that.
Good luck.
use below method to handle back button pressed.
public void onBackPressed()
{
super.onBackPressed();
}
You need to overwrite the onBackPressed method.
#Override
public void onBackPressed() {
super.onBackPressed(); // remove this if u want to handle this event
}
Use the code below
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
exitByBackKey();
//moveTaskToBack(false);
return true;
}
return super.onKeyDown(keyCode, event);
}
protected void exitByBackKey() {
AlertDialog alertbox = new AlertDialog.Builder(this)
.setMessage("Do you want to exit application?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
// do something when the button is clicked
public void onClick(DialogInterface arg0, int arg1) {
finish();
//close();
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
// do something when the button is clicked
public void onClick(DialogInterface arg0, int arg1) {
}
})
.show();
}
#Override
public void onBackPressed()
{
super.onBackPressed();
}
Declare this on your activity. super.OnBackPressed automatically calls back method in android. it will surely cancel your dialog.
in addition, your dialog must look like this.
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder1.setMessage("TEST DIALOG.\n");
builder1.setPositiveButton("Ok",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
Toast.makeText(MainActivity.this, "This Is test Dialog", Toast.LENGTH_SHORT).show();
}
});
AlertDialog alert11 = builder1.create();
alert11.show();
or you can set Negative button..
Hope this helps!
Define a custom layout and override dispatchKeyEvent, for example:
public class CustomSystemAlertWindow extends FrameLayout {
public static final String TAG = "CustomSystemAlertWindow";
private WeakReference<Context> mContext;
public CustomSystemAlertWindow(Context context) {
super(context);
mContext = new WeakReference<Context>(context);
// Set a background color to identify the view on the screen
this.setBackgroundColor(getResources().getColor(android.R.color.holo_red_light));
}
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if (event != null && event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
Log.d(TAG, "back button pressed");
if (mContext != null && mContext.get() != null) {
WindowManager wm = (WindowManager) mContext.get().getSystemService(Context.WINDOW_SERVICE);
wm.removeView(this);
}
return true;
}
return super.dispatchKeyEvent(event);
}
}
Then add the view with this code:
CustomSystemAlertWindow customSystemAlertWindow = new CustomSystemAlertWindow(context);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
PixelFormat.TRANSLUCENT);
WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
wm.addView(customSystemAlertWindow, params);
When you press the back button the view will dismiss.
Show the Alert window through the Activity so you can detect it.
Implement the code to detect easily Back Button or Home Button pressed.
public class alertPopup extends Activity {
Context context;
final AlertDialog alertDialog;
String TAG = "your Activity Name"
boolean homePressed = false; // to detect the Homebutton pressed
#Override
public void onCreate(Bundle savedInstanceState) {
AlertDialog.Builder builder = newAlertDialog.Builder(YourActivity.this, R.style.AppCompatAlertDialogStyle);
builder.setTitle("AlertDialog Title");
..........
....... // Build ur AlertDialog
alertDialog= builder.create();
alertDialog.show();
//to detect Alert Dialog cancel when user touches outside the Dialog prompt
alertDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
#Override
public void onCancel(DialogInterface dialog) {
Log.v(TAG,"Alert Dialog cancelled when user touches outside the Dialog prompt")
}
});
}
#Override
public void onBackPressed()
{
Log.v(TAG,"Back Button Pressed");
super.onBackPressed();
alertDialog.dismiss(); //dismiss the alertDialog
alertPopup.this.finish(); // Destroy the current activity
homePressed = false;
}
#Override
public void onResume() {
super.onResume();
homePressed = true; // default: other wise onBackPressed will set it to false
}
#Override
public void onPause() {
super.onPause();
if(homePressed) {
alertDialog.dismiss(); //dismiss the alertDialog
alertPopup.this.finish(); // Destroy the current activity
Log.v(TAG, "Home Button Pressed"); }
}
public void onDestroy(){
super.onDestroy();
}
}
Note:
Add this Permission in Android Manifest to show the alert Window .
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
Happy Coding :)
I understand that you are using the <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" /> permission for showing a floating view.
Using a floating view you can intercept the back button press, but the home button press cannot be intercepted (android won't let you primarily because of security reasons).
To intercept the back button press you need to add a wrapper when you inflate your floating view.
Your wrapper should look like this:
// Wrapper for intercepting System/Hardware key events
ViewGroup wrapper = new FrameLayout(this) {
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if (event.getKeyCode()==KeyEvent.KEYCODE_BACK) {
hideAddNotesFloatingView();
return true;
}
return super.dispatchKeyEvent(event);
}
};
Then you add it to your floating view as a root:
mAddNoteFloatingView = mInflater.inflate(R.layout.floating_add_note, wrapper);
My complete code looks like this:
private void addFloatingView() {
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_PHONE,
0,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.CENTER | Gravity.LEFT;
params.x = 0;
params.y = 0;
// Wrapper for intercepting System/Hardware key events
FrameLayout wrapper = new FrameLayout(this) {
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if (event.getKeyCode()==KeyEvent.KEYCODE_BACK) {
// Add your code for handling the back button press
return true; // Return true means that the event was handled
}
return super.dispatchKeyEvent(event);
}
};
mAddNoteFloatingView = mInflater.inflate(R.layout.floating_view, wrapper);
mWindowManager.addView(mAddNoteFloatingView, params);
}
It's simple. Follow these steps:
Create a view like Relative Layout, Linear Layout or Frame Layout Dynamically. 2. Override the dispatchKeyEvent while creating the view.
Add your original view into this dynamically created view with addView() method.
Add the dynamically created view to your Window Manager or Alert Dialog whichever you want.
In addition to #Eliran Kuta's solution, this is more simple answer for Back button.
val view = getAlertView()
val windowParam = WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT, // whatever
WindowManager.LayoutParams.WRAP_CONTENT, // whatever
WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY, // use WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY before Oreo
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, // whatever
PixelFormat.TRANSLUCENT // whatever
)
view.isFocusableInTouchMode = true
view.setOnKeyListener { view, keyCode, event ->
when (keyCode) {
KeyEvent.KEYCODE_BACK -> {
// do your work here
true
}
else -> false
}
}
val windowManager = getSystemService(Context.WINDOW_SERVICE) as WindowManager
windowManager.addView(view, windowParam)

Hee guys,
So currently I'm using a PopupWindow to display an in app browser. However when pressing the back button it does nothing. I'm using the PopupWindow in another Fragment, then I use a statement to set the PopupWindow in my FragmentActivity and then when I press my back button it should check if the PopupWindow is set or not and dismiss it or not. However it doesn't even run through the onBackPressed.
PopupWindow in fragment:
--> is where I point out the line which makes sure the FragmentActivity gets the PopupWindow as well.
// Use webview for icons and website link.
public void inAppBrowser(String url){
mCursor.moveToFirst();
// Inflate View
LayoutInflater layoutInflater = (LayoutInflater) ((MainActivity) MainActivity.getContext()).getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View inflatedView = layoutInflater.inflate(R.layout.browser_window, null, false);
// Control View Childs.
LinearLayout header = (LinearLayout) inflatedView.findViewById(R.id.filter_header);
header.setBackgroundColor(Color.parseColor(color));
Button cancel = (Button) inflatedView.findViewById(R.id.cancel);
Button done = (Button) inflatedView.findViewById(R.id.done);
// Set PopupWindow position.
Display display = ((MainActivity) MainActivity.getContext()).getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
// Control PopupWindow.
final PopupWindow popWindow = new PopupWindow(inflatedView, size.x, size.y, true);
popWindow.setAnimationStyle(android.R.anim.fade_in);
popWindow.setFocusable(true);
popWindow.setOutsideTouchable(true);
popWindow.showAtLocation(v, Gravity.BOTTOM, 0, 150);
--> MainActivity.setPopupWindow(popWindow);
// Control WebView
WebView myWebView = (WebView) inflatedView.findViewById(R.id.webview);
myWebView.setWebViewClient(new WebViewClientAdapter());
myWebView.clearCache(true);
myWebView.clearHistory();
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
MainActivity.setWebView(myWebView);
if (url != null) {
if (url.contains("http://") || url.contains("https://")) {
} else {
url = "http://" + url;
}
myWebView.loadUrl(url);
} else {
popWindow.dismiss();
MainActivity.setPopupWindow(null);
MainActivity.setWebView(null);
}
cancel.setVisibility(View.INVISIBLE);
done.setText("Close");
done.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
popWindow.dismiss();
}
});
}
My onBackPressed code :
#Override
public void onBackPressed() {
// TODO Auto-generated method stub
//check if popupwindow is open
Log.e(TAG, "Check if it runs through this section");
if (popWindow != null) {
if (myWebView != null && myWebView.canGoBack()) {
myWebView.goBack();
} else {
popWindow.dismiss();
popWindow = null;
myWebView = null;
}
}
}
Ignore the WebView for now. That might be a question in the future, but I want the PopupWindow to close first. Any help is appreciated.
Make your PopupWindow not focusable:
final PopupWindow popWindow = new PopupWindow(inflatedView, size.x, size.y, false);
Also remove this line which was redundant:
popWindow.setFocusable(true);
I think you should define a static method removePopupWindow(view v) in MainActivity,
and call it inside onBackPressed() like MainActivity.removePopupWindow(popWindow);
Hope It will help you.
Ok, so this question was asked a long time ago, but I think I have a better solution. What I've done is add an OnDismissListener to my popup. In this listener I've added the code I wanted to execute when the popup got dismissed. This way Android still get's to manage the opening and closing of the popup and I just added a single line to make it work.
This is the way to add one:
yourAwesomePopupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
#Override
public void onDismiss() {
// Your code on dismiss here
}
});
popup.showAtLocation(popupView, Gravity.CENTER,0,0);
popupshowing=true;// define this as a global
#Override
public void onBackPressed() {
if(popupshowing) {
popup.dismiss();
popupshowing=false;
}
else {
super.onBackPressed();
}
}
You can use this.
Dialog dialog = new Dialog(ActivityMain.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_TOAST); dialog.setContentView(R.layout.mydialog);
dialog.setCancelable(true);
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
try {
if (mScannerView!=null) {
mScannerView.stopCamera();
}
} catch(Exception e){
e.printStackTrace();
}
}
});
Scenario:
There is an activity and a dialog.The Activity has a button to launch that shows the Dialog on screen.
Problem:
when Dialog the is showing and I touch the button (instead of single tap), Dialog becomes invisible but quickly shows up again ! I want to touch outside of the dialog but do not show The dialog again.
How can this be done? Or is there another fix ?
here is my Activity
public class MyAndroidAppActivity extends Activity {
Button button;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
CallDialog call = new CallDialog();
call.show(this);
}
});
}
}
And my Dialog
public class CallDialog{
Dialog mDialog;
public void show(Context context){
Dialog mDoialog = new Dialog(context);
setContentView(R.layout.dialog);
Window window = this.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
window.setFlags(WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);
getWindow().getDecorView().getRootView().setOnTouchListener(new OnTouchListener(){
#Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_OUTSIDE){
mDialog.dismiss();
}
return false;
}
});
}
}
There seems no need to set touch listener for root view, you can control the same thing by invoke setCanceledOnTouchOutside();
/**
* Sets whether this dialog is canceled when touched outside the window's
* bounds. If setting to true, the dialog is set to be cancelable if not
* already set.
*
* #param cancel Whether the dialog should be canceled when touched outside
* the window.
*/
public void setCanceledOnTouchOutside(boolean cancel) {
if (cancel && !mCancelable) {
mCancelable = true;
}
mWindow.setCloseOnTouchOutside(cancel);
}
And it's default set false so it can dismiss when touch outside the dialog .
I'm using Immersive Mode for an activity with videoView inside.
My goal is when touch on screen, the media controller and the system control bar show or disappear together. Everything works fine now.
The problem is I can't leave activity properly. When I press the back button once, the system bar just hide again and nothing happens. I have to press twice to exit the activity. I don't know why.
Here's my code.
I use an FullScreenActivity() activity to define IMMERSIVE MODE:
#TargetApi(Build.VERSION_CODES.KITKAT)
private void FullScreenActivity() {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav // bar
| View.SYSTEM_UI_FLAG_FULLSCREEN// hide status bar;
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}
in OnCreate():
#Override
protected void onCreate(Bundle savedInstanceState) {
//getActionBar().setDisplayShowTitleEnabled(false);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
FullScreenActivity();
And in the media controller, I define the IMMERSIVE MODE again, because if I don't after the controller shows, the actionbar and system bar will be back again.
private class MyController extends MediaController {
public MyController(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public boolean onTouchEvent(MotionEvent event) {
//........
}
#Override
public void show() {
super.show();
FullScreenActivity();
}
#Override
public void hide() {
super.hide();
FullScreenActivity();
}
}
and at last, in the onBackPressed(), I implemented my function:
#Override
public void onBackPressed() {
Toast.makeText(getApplicationContext(), "onbackpressed", Toast.LENGTH_SHORT).show();
super.onBackPressed();
if (tgtIDArr != null && tgtIDArr.size() > 0) {
new AlertDialog.Builder(this)
.setIcon(android.R.drawable.ic_dialog_alert)
.setTitle("Exit Player!")
.setMessage("Are you sure you want to leave Player?")
.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog,
int which) {
.......
finish();
}
}).setNegativeButton("No", null).show();
}else{
........
finish();
}
}
I don't know why, but only when I press back button twice would trigger this onBackPressed() function.
Anyone knows why? thanks!!
If you want to exit the activity when the back button is pressed and the media controller is visible then you can intercept the back button with the following code snippet.
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
int keyCode = event.getKeyCode();
if (keyCode == KeyEvent.KEYCODE_BACK) {
finish();
return true;
}
return super.dispatchKeyEvent(event);
}
Which is the same solution to a similar problem here Back button not working in Media player
I am having problem on back button of hardware. In my main Activity, I have one List view(say 1). When I click on item of this List view(1), one Alert Dialog appears, in this alert dialog, there is one List view(say 2). Data of this List view(2) are being repeated when I press back button of hardware. I have also put cancel image on this alert dialog to dismiss, when I press this cancel image, data are not being repeated. I tried different methods onResume(), onPause(), onDestroy(), onRestart() to clear the array for List view(2), but nothing works. Here is my code...
case LIST_DIALOG :
LayoutInflater inflater2 = LayoutInflater.from(this);
View dialogview1 = inflater2.inflate(R.layout.listdialog, null);
AlertDialog.Builder dialogbuilder2 = new AlertDialog.Builder(this);
dialogbuilder2.setView(dialogview1);
dialogDetails = dialogbuilder2.create();
case LIST_DIALOG:
AlertDialog alertDialog1 = (AlertDialog) dialog;
// Cancel Alert Dialog
ImageView ivCancel = (ImageView) alertDialog1.findViewById(R.id.imgCancel);
ivCancel.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
dismissDialog(LIST_DIALOG);
arr2.clear();
}
});
// Friend List
showFriendList();
break;
// List view data are inserted with this function call
private void showFriendList() {
// TODO Auto-generated method stub
Request.executeMyFriendsRequestAsync(friendSession, new GraphUserListCallback() {
#Override
public void onCompleted(List<GraphUser> users, Response response) {
// TODO Auto-generated method stub
// arr2 = new ArrayList<String>();
for(GraphUser user : users)
{
arr2.add(user.getName());
}
adapter2 = new ArrayAdapter<String>(getBaseContext(), R.layout.single_row, R.id.txt,arr2);
lvDialog.setAdapter(adapter2);
lvDialog.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
adapter2.notifyDataSetChanged();
itemCount = lvDialog.getCount();
Toast.makeText(getBaseContext(), "" + itemCount, 1000).show();
}
});
}
// I tried these methods, but nothing works...
#Override
public void onResume()
{
super.onResume();
ShowSavedFiles();
arr2.clear();
}
#Override
public void onPause()
{
super.onPause();
arr1.clear();
arr2.clear();
}
#Override
public void onBackPressed() {
//super.onBackPressed();
// finish your Activity
arr2.clear();
return;
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
arr2.clear();
dismissDialog(LIST_DIALOG);
}
return false;
}
I'm not sure but might be adding the following code to your onKeyDown method might help out :
return super.onKeyDown(keyCode, event);
I am writing an application to animate popup window. It was working great with my code.
I want to close the popup window(i.e to slide-down it), when back button is pressed on device.
But I couldn't listen any one key from device. I used setOnKeyListener of that popup window, I didn't even get log from it.
My Code is given below:
popup_layout = layoutInflater.inflate(R.layout.popup_addchannel, null);
popupWindow = new PopupWindow(popup_layout, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
subscribeButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Log.d(TAG,
// "Button is clicked for animation.... Visibility is"
// + subscribeButton.getVisibility());
openMenu(view);
}
});
popup_layout.setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
Log.d(TAG, "on key button click called.........");
return false;
}
});
public void openMenu(View view) {
if (!flag) {
popupWindow.setAnimationStyle(R.style.PopupWindowAnimation);
popupWindow.showAtLocation(view.findViewById(R.id.button1),
Gravity.CENTER, 0, 0);
popupWindow.setFocusable(true);
popupWindow.update();
flag = true;
} else {
popupWindow.dismiss();
popupWindow.setFocusable(false);
flag = false;
}
}
What is the problem behind this?
Shall i achieve my requirement?
Please, Guide me.
Thank you in Advance!
try this....
final PopupWindow popupWindow = new PopupWindow(popupView,
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT,true);
...
popupWindow.getContentView().setFocusableInTouchMode(true);
popupMenu.getContentView().setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_MENU &&
event.getRepeatCount() == 0 &&
event.getAction() == KeyEvent.ACTION_DOWN) {
// ... payload action here. e.g. popupMenu.dismiss();
return true;
}
return false;
}
});
The dialog has a property of cancelling the dialog on back press.
dialog.setCancelable(true);
EDIT: Check Qberticus answer on this link: Android popup window dismissal
and you can also see: Issue dismissing popup window
Yes you can use this
dialog_obj.setCancelable(true);
You should override the onKeyPressed() method of your activity as below.
#Override
public void onBackPressed() {
super.onBackPressed();
//your code to close the popup window.
popupWindow.setAnimationStyle(R.style.PopupWindowAnimation);
popupWindow.showAtLocation(view.findViewById(R.id.button1),
Gravity.CENTER, 0, 0);
opupWindow.setFocusable(true);
popupWindow.update();
flag = true;
}
popupWindow.getContentView().setOnClickListener(new OnClickListener()) {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
popupWindow.dismiss();
}
});
Try this.
You can't listen a key press in popup window, but when you listen to system back key, you can override dismiss() method to intercept it.
