I have an Android app with a Service to Overlay a button on Android (like Facebook chat bubble).
I want to show a layout (overlay.xml) when the user click on the icon but I can't show the layout with the good dimension.
This is my result :
This is my OverlayShowingService.class :
public class OverlayShowingService extends Service {
private WindowManager windowManager;
private ImageView chatHead;
private Boolean _enable = true;
#Override
public IBinder onBind(Intent intent) {
_enable=false;
return null;
}
#Override
public void onCreate() {
super.onCreate();
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
chatHead = new ImageView(this);
chatHead.setImageResource(R.mipmap.ic_launcher);
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;
params.y = 100;
windowManager.addView(chatHead, params);
chatHead.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.overlay, null);
final PopupWindow popupWindow = new PopupWindow(popupView,
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
popupWindow.update();
Button btnDismiss = (Button)popupView.findViewById(R.id.dismiss);
Button endService= (Button) popupView.findViewById(R.id.endService);
endService.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
stopSelf();
Toast.makeText(getApplicationContext(), "Service Terminated", Toast.LENGTH_LONG).show();
}
});
btnDismiss.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Toast.makeText(getApplicationContext(), "Popup Terminated", Toast.LENGTH_LONG).show();
popupWindow.dismiss();
_enable=true;
}
});
if(_enable){
popupWindow.showAsDropDown(chatHead, 50, -30);
_enable=false;
}
else if(!_enable) {
Log.d("FALSE", "FALSE");
}
}
});
try {
chatHead.setOnTouchListener(new View.OnTouchListener() {
private WindowManager.LayoutParams paramsF = params;
private int initialX;
private int initialY;
private float initialTouchX;
private float initialTouchY;
#Override public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
initialX = paramsF.x;
initialY = paramsF.y;
initialTouchX = event.getRawX();
initialTouchY = event.getRawY();
break;
case MotionEvent.ACTION_UP:
break;
case MotionEvent.ACTION_MOVE:
paramsF.x = initialX + (int) (event.getRawX() - initialTouchX);
paramsF.y = initialY + (int) (event.getRawY() - initialTouchY);
windowManager.updateViewLayout(chatHead, paramsF);
break;
}
return false;
}
});
} catch (Exception ignored) {}
}
#Override
public void onDestroy() {
super.onDestroy();
if (chatHead != null) windowManager.removeView(chatHead);
}
}
This is the layout overlay.xml :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp"
android:orientation="vertical"
android:layout_margin="5dp"
android:background="#545454">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="It's a PopupWindow"
android:textSize="40sp"
android:textColor="#ffffff" />
<Button
android:id="#+id/dismiss"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Dismiss Popup"
android:textColor="#ffffff" />
<Button
android:id="#+id/endService"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Finish Service"
android:textColor="#ffffff" />
</LinearLayout>
Edit: This is an alternate approach that mimics a popup window. I have kept the first answer with a altert dialog approach after the following explanation and code. Either way will work, but this new way may be preferable since it looks more like a popup window.
This approach simply adds the overlay.xml layout into a view that is place on the screen just like the chatHead view is.
OverlayShowingService.java
public class OverlayShowingService extends Service {
private WindowManager windowManager;
private ImageView chatHead;
private Boolean _enable = true;
#Override
public IBinder onBind(Intent intent) {
_enable = false;
return null;
}
#Override
public void onCreate() {
super.onCreate();
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
chatHead = new ImageView(this);
chatHead.setImageResource(R.mipmap.ic_launcher);
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;
windowManager.addView(chatHead, params);
chatHead.post(new Runnable() {
#Override
public void run() {
params.x = (int) chatHead.getBottom() + 50;
params.y = (int) chatHead.getRight() - 30;
}
});
chatHead.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
final View popupView = layoutInflater.inflate(R.layout.overlay, null);
final PopupWindow popupWindow = new PopupWindow(popupView,
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.update();
Button btnDismiss = (Button) popupView.findViewById(R.id.dismiss);
Button endService = (Button) popupView.findViewById(R.id.endService);
endService.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
windowManager.removeViewImmediate(popupView);
stopSelf();
Toast.makeText(getApplicationContext(), "Service Terminated", Toast.LENGTH_LONG).show();
}
});
btnDismiss.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Toast.makeText(getApplicationContext(), "Popup Terminated", Toast.LENGTH_LONG).show();
// popupWindow.dismiss();
windowManager.removeViewImmediate(popupView);
_enable = true;
}
});
if (_enable) {
windowManager.addView(popupView, params);
// popupWindow.showAsDropDown(chatHead, 50, -30);
_enable = false;
} else if (!_enable) {
Log.d("FALSE", "FALSE");
}
}
});
try {
chatHead.setOnTouchListener(new View.OnTouchListener() {
private WindowManager.LayoutParams paramsF = params;
private int initialX;
private int initialY;
private float initialTouchX;
private float initialTouchY;
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
initialX = paramsF.x;
initialY = paramsF.y;
initialTouchX = event.getRawX();
initialTouchY = event.getRawY();
break;
case MotionEvent.ACTION_UP:
break;
case MotionEvent.ACTION_MOVE:
paramsF.x = initialX + (int) (event.getRawX() - initialTouchX);
paramsF.y = initialY + (int) (event.getRawY() - initialTouchY);
windowManager.updateViewLayout(chatHead, paramsF);
break;
}
return false;
}
});
} catch (Exception ignored) {
}
}
#Override
public void onDestroy() {
super.onDestroy();
if (chatHead != null) windowManager.removeView(chatHead);
}
}
The first approach using an alert dialog.
Your code works as-is for API 21 and below. Something changed with API 22 that is prohibiting what you want to do.
I think the primary issue is with the popup and the service environment. I have modified your code to use an AlertDialog with the type TYPE_SYSTEM_ALERT. Although the styling is not what you want, it does work otherwise. You may be able to get it to style differently if you play with it a little.
Another alternative would be to start an activity from your service. An activity-based approach will present you with a more pliable (and forgiving) environment to do what you want with the UI. (This is not as straight-forward as one may think.)
Below is the code that works as a system-level alert. Here is a screen shot.
OverlayShowingService
chatHead.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
final AlertDialog alertDialog = new AlertDialog.Builder(arg0.getContext(),
R.style.Theme_AppCompat_Dialog_Alert).create();
LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
final View popupView = layoutInflater.inflate(R.layout.overlay, null);
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
alertDialog.setView(popupView);
Button btnDismiss = (Button) popupView.findViewById(R.id.dismiss);
Button endService = (Button) popupView.findViewById(R.id.endService);
endService.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
alertDialog.dismiss();
stopSelf();
Toast.makeText(getApplicationContext(), "Service Terminated", Toast.LENGTH_LONG).show();
}
});
btnDismiss.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Toast.makeText(getApplicationContext(), "Popup Terminated", Toast.LENGTH_LONG).show();
alertDialog.dismiss();
}
});
alertDialog.show();
}
});
As I stated in my first answer, you are having this issue with API 22 and later. Your code works OK for API 21 and earlier.
You are running afoul of changes made to PopupWindow in API level 22. See this documentation.
Fix issue #17789629: PopupWindow overlaps with navigation bar.
The Lollipop release introduced a feature that allowed
apps to extend under the navigation bar. This also means
any popup window that is anchored to the bottom of its
parent window will overlap with the navigation bar if the
parent window is extending underneath the navigation bar.
This change introduces a new window flag
(FLAG_LAYOUT_ATTACHED_IN_DECOR) that allows the app to
specify if the popup window should be attached to the decor
frame of the parent window thereby avoiding an overlap
with the screen decorations.
By default the flag is set on SDK version LOLLIPOP_MR1 or
greater and cleared on lesser SDK versions.
You can turn off this flag with the setAttachedInDecor method of PopupWindow.
Add the following code to OverlayShowingService.java after popupWindow.update() in the OnClickListener and you should be good to go.
// Turn off this functionality introduced in API 22.
// See documentation for FLAG_LAYOUT_ATTACHED_IN_DECOR in
// WindowManager.LayoutParams
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP) {
popupWindow.setAttachedInDecor(false);
}

Why not working:
In 7.1 everything is working fine i get the call and the chathead apears.
In 4.4 [LG] I receive the call but nothing happens.
In 4.4 [BQ] Aplication crashes.
Any help?
Found the problem.
Where I'm calling startActivity from outside an activity like:
context.startActivity(new Intent(context, FloatingActivity.class)
.putExtra("PHONE", TelephonyManager.EXTRA_INCOMING_NUMBER));
in android 4.4 it is required to set the flag Intent.FLAG_ACTIVITY_NEW_TASK
o in all ocurrencies i need to call it like:
context.startActivity(new Intent(context, FloatingActivity.class)
.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
.putExtra("PHONE", TelephonyManager.EXTRA_INCOMING_NUMBER));
I have an Overlay Button in my Android app. I want to show a layout and interact with the views of my Layout when the user click on the button.

Send a broadcast when then the button is clicked and start activity from Broadcast receivers onReceive method.
Create a broadcast receiver,Register a Broadcast reciever onCreate() of your service then. Broadcast intent when the button is clicked. Finally the receiver will open a Activity(layout) when the overlay button is clicked.
If you only wanted to open a dialog this is a decent answer. https://stackoverflow.com/a/31221355/4179914
Turns out you can also theme a activity like a dialog as mentioned here
https://stackoverflow.com/a/7918720/4179914
public class OverlayClickReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent toDialog = new Intent(context, Main2Activity.class);
toDialog.setFlags(FLAG_ACTIVITY_NEW_TASK);
context.startActivity(toDialog);
}
}
Send Broadcast on overlay button clicked.
#Override
public void onClick(View v) {
broadcastClick();
}
private void broadcastClick() {
final Intent intent = new Intent("user.clicked.overlay.button");
final LocalBroadcastManager broadcastManager = LocalBroadcastManager.getInstance(this);
broadcastManager.sendBroadcast(intent);
}
Register Broadcast receiver onCreate()
#Override
public void onCreate() {
super.onCreate();
overlayShowing = new OverlayClickReceiver();
.......
}
private void registerClickReceiver() {
LocalBroadcastManager.getInstance(this).registerReceiver(overlayShowing,
new IntentFilter("user.clicked.overlay.button"));
}
Unregister Broadcast receiver onDestroy()
#Override
public void onDestroy() {
super.onDestroy();
..........
unregisterClickReceriver();
}
private void unregisterClickReceriver() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(overlayShowing);
}
From what i understood from the question, you want to get a view form xml files and add it to a window.
You can use View view = LayoutInflater.from(context).inflate(r.layout.overlay,null,false); and add that view with WindowManager.addView(view) to the window.
I have spend like 2 hours,
I'm unable to figure out what is the issue in service. I'm not calling stopService() or stopSelf from anywhere else. Below is the code ,
public class FloatingViewService extends Service {
private WindowManager mWindowManager;
private View mFloatingView;
WindowManager.LayoutParams params,landscapeParams,nonTouchableParams;
public FloatingViewService() {

#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
//Inflate the floating view layout we created
mFloatingView = LayoutInflater.from(this).inflate(R.layout.layout_floating_widget, null);
//Add the view to the window.
params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,

//Specify the view position
params.gravity = Gravity.TOP | Gravity.LEFT; //Initially view will be added to top-left corner
params.x = 0;
params.y = 100;
//Add the view to the window.
landscapeParams = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
//Specify the view position
landscapeParams.gravity = Gravity.TOP | Gravity.LEFT; //Initially view will be added to top-left corner
landscapeParams.x = 0;
landscapeParams.y = 100;
//Add the view to the window.
nonTouchableParams = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,
PixelFormat.TRANSLUCENT);
//Specify the view position
nonTouchableParams.gravity = Gravity.TOP | Gravity.LEFT; //Initially view will be added to top-left corner
nonTouchableParams.x = 0;
nonTouchableParams.y = 100;
//Add the view to the window
mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
mWindowManager.addView(mFloatingView, params);
//The root element of the collapsed view layout
final View collapsedView = mFloatingView.findViewById(R.id.collapse_view);
//The root element of the expanded view layout
final View expandedView = mFloatingView.findViewById(R.id.expanded_container);
//Set the close button
ImageView closeButtonCollapsed = (ImageView) mFloatingView.findViewById(R.id.close_btn);
closeButtonCollapsed.setOnClickListener(new View.OnClickListener() {
#Override

}
});
//Set the close button

}
});

I am not able to figure out anomalous behaviour help me out.
Start your service as forground.
https://developer.android.com/reference/android/app/Service.html#startForeground(int, android.app.Notification)
Since you want your service to run continuously you will have to override the onStartCommand method and return START_STICKY
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
return START_STICKY;
}
For started services, there are two additional major modes of operation they can decide to run in, depending on the value they return from onStartCommand(): START_STICKY is used for services that are explicitly started and stopped as needed, while START_NOT_STICKY or START_REDELIVER_INTENT are used for services that should only remain running while processing any commands sent to them. See the linked documentation for more detail on the semantics.
https://developer.android.com/reference/android/app/Service.html
I have opened a window(displayed on top of other activities) on clicking floating view(similar to FB chat head), how to close window when device back button is pressed. Below is my service code
public class ServiceFloating extends Service {
public static int ID_NOTIFICATION = 2018;

params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;

windowManager.addView(chatHead, params);
try {
chatHead.setOnTouchListener(new View.OnTouchListener() {

#Override public boolean onTouch(View v, MotionEvent event) {

// Get current time in nano seconds.
long pressTime = System.currentTimeMillis();
// If double click...
if (pressTime - lastPressTime <= 300) {
createNotification();

}

mHasDoubleClicked = false;
}

I couldn't add onBackPressed or a onKeyEvent methods inside the service. Please suggest a workaround. TIA
You should handle your view only from activity and use communication components such service binding or broadcasts. You shouldn't create views from service, its not appropriate.
I am new at android programming. I have created a button using system overlay and a service. Now what I want is to click that button and get another overlay window of more 5 buttons. But the problem is that button doesn't take any click and don't allow me to open another overlay window. Here is the xml code I have used to draw the button--
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:id="#+id/l1"
android:layout_height="fill_parent"
tools:context=".OverlayActivity" >
<Button
android:id="#+id/mainButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAlignment="center"
android:gravity="center_vertical"
android:layout_alignParentRight="true"
android:layout_centerInParent="true"
android:clickable="true"
android:visibility="visible"
android:focusable="true">
</Button>
and here is the code I have used to show the overlay button
#Override
public void onCreate() {
super.onCreate();
LayoutInflater layoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View oView = layoutInflater.inflate(R.layout.activity_overlay, null);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
0 | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
PixelFormat.TRANSLUCENT);
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(oView, params);
Button button = (Button)oView.findViewById(R.id.mainButton);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Toast.makeText(OverlayService.this, "GotCha!!! ", Toast.LENGTH_LONG).show();
}
});
ViewGroup vg = (ViewGroup)oView.findViewById(R.id.l1);
final Display metrics = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
vg.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
switch(event.getActionMasked()){
case MotionEvent.ACTION_MOVE:
int x = (int)event.getX() - offset_x;
int y = (int)event.getY() - offset_y;
int w = metrics.getWidth()-100;
int h = metrics.getHeight()-100;
if(x > w){
x = w;
}
if(y > h){
y = h;
}
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
new ViewGroup.MarginLayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
lp.setMargins(x, y, 0, 0);
selected_item.setLayoutParams(lp);
break;
default:
break;
}
return true;
}
});
button.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
switch(event.getActionMasked()){
case MotionEvent.ACTION_DOWN:
offset_x = (int)event.getX();
offset_y = (int)event.getY();
selected_item = v;
break;
default:
break;
}
return false;
}
});
}
Any ideas guys? I am running out of time..Please
Better you use fragment for this
Create views using fragments, overlay a button above the fragment.
