I have made a service that puts black rectangle on top of every activity and the screen goes black except status/notification bar and navigation bar. My goal is to hide everything. How can I make this black rectangle go fullscreen? I have tried using FLAG_FULLSCREEN and FLAG_LAYOUT_IN_SCREEN, but it didn't work. I have read about disabling the TypeGuard, but even that didn't work. Thanks in advance!
Here is my code
WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
ImageView black = new ImageView(this);
black.setImageResource(R.drawable.black);
LinearLayout layout = new LinearLayout(this);
layout.addView(black);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;
params.y = 0;
windowManager.addView(layout, params);
i solved this issue just simply adding one line
layout.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);
I solved this program
if (null == mInflater) {
mInflater = (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}if (mLockscreenView == null) mLockscreenView = mInflater.inflate(R.layout.view_locokscreen, null);
mLockscreenView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
mWindowManager.addView(mLockscreenView, mParams);
final Handler handler = new Handler();
mLockscreenView.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
#Override
public void onSystemUiVisibilityChange(int visibility) {
handler.postDelayed(new Runnable() {
#Override
public void run() {
mLockscreenView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
}
},2000);
}
});
Try this:
assert getSupportActionBar() != null;
getSupportActionBar().hide();
mContentView = findViewById(R.id.fullscreen_content);
mContentView.setSystemUiVisibility(View.GONE | View.SYSTEM_UI_FLAG_FULLSCREEN);
Where fullscreen_content is the parent layout.

I have a service from which I want to show a layout using a window manager which I successfully implemented but I need to do 2 things I want to access a button in layout and prevent from outside touch. How do I do that
final WindowManager windowManager=(WindowManager)getSystemService(WINDOW_SERVICE);
LayoutInflater inflater=(LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
final RelativeLayout layout=(RelativeLayout) inflater.inflate(R.layout.sheet,null);
cancel = layout.findViewById(R.id.img_cancel);
cancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
windowManager.removeViewImmediate(layout);
}
});
WindowManager.LayoutParams p = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.RGBA_8888);
p.gravity = Gravity.BOTTOM;
windowManager.addView(layout,p);
Add these flags
WindowManager.LayoutParams p = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
Build.VERSION.SDK_INT >= Build.VERSION_CODES.O ? LayoutParams.TYPE_APPLICATION_OVERLAY : LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
| WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
| WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.RGBA_8888);
Window window = this.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
Override onTouchEvent() of dialog
public boolean onTouchEvent(MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_OUTSIDE){
System.out.println("TOuch outside the dialog ******************** ");
}
return false;
}
In service for displaying custom view over all windows I need to set onClick listener.
#Override public void onCreate() {
super.onCreate();
mContext = this;
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout parent = (LinearLayout) inflater.inflate(R.layout.result_layout,
null);
// Here i need to add onClick listener
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.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(parent, params);
}
I tried to create button lister from inflater but without luck. What is the right approach to set click event listener for selected button by button ID?
Many thanks for any advice.
Resolved using the following code which is works in the service well:
#Override public void onCreate() {
super.onCreate();
mContext = this;
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
final LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mParentLayout = (LinearLayout) inflater.inflate(R.layout.result_layout,
null);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.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(mParentLayout, params);
Button b = (Button) mParentLayout.findViewById(R.id.closeButton);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
windowManager.removeView(mParentLayout);
}
});
}
Inspired from:
Could not get Touch event for TYPE_SYSTEM_OVERLAY
Android can play tricks on what you think might work, but doesn't.
First, What I typically do is from onCreate() I place a call to:
InitializePage(); where I then put all my initialize code. It's just my style.
Then in my InitializePage() function I initialize the button, then enter the OnClickListener. I use Android Studio with Intellisense so it writes the code for me....
mSendButton = (TextView)findViewById(R.id.send_button1);
mSendButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{.....
});
It should be that easy. Good luck
How can longclick to select a text in WebView in a Service. I added a WebView by the WindowManager, when a url is loaded and a longclick to select text is done. The selected text is not visible and can not be selected.
How can I fix it ?
public class BtService extends Service {
#Override
public IBinder onBind(Intent intent) {
return null;
}
public static final int WINDOW_EXPAND_FLAGS = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
| WindowManager.LayoutParams.FLAG_DIM_BEHIND
| WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
| WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH;
#Override
public void onCreate() {
super.onCreate();
WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WINDOW_EXPAND_FLAGS, PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;
params.y = 0;
params.width = WindowManager.LayoutParams.MATCH_PARENT;
params.height = WindowManager.LayoutParams.MATCH_PARENT;
LinearLayout view = new LinearLayout(this);
view.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));
WebView wv = new WebView(this);
wv.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
view.addView(wv);
wv.loadUrl("https://tinhte.vn");
windowManager.addView(view, params);
}}
Also this will require the android.permission.SYSTEM_ALERT_WINDOW permission.
When webview loaded, longclick in text to select text,-> action mode don't show
here is the service that i have called to display view above locked screen.i dont want to unlock lock screen i want something that whatsapp and skype use for their calling screen.such that screen is not unlocked.
public class Display extends Service {
private static WindowManager wm;
private static RelativeLayout ly;
private WindowManager.LayoutParams params;
#Override
public void onCreate() {/
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
LayoutInflater vi;
vi = LayoutInflater.from(this);
ly = (RelativeLayout) vi.inflate(R.layout.display, null);
wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT |
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
/*ALSO TRIED USING WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
| WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
| WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON*/
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.RGBA_8888);
params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;
params.y = 300;
ly.setLayoutParams(params);
TextView tv = (TextView) ly.findViewById(R.id.annotationTextView);
tv.setText("check");
wm.addView(ly, params);
return START_NOT_STICKY;
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onDestroy() {
}
}
but the screen was appearing below locked screen.
params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.WRAP_CONTENT,
// WindowManager.LayoutParams.TYPE_SYSTEM_ALERT |
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
| WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
| WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
| WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED,
PixelFormat.RGBA_8888);
worked for me but i was not able to touch on it so still unsuccessful
I'm trying to create a custom chatHead which would show only when a particular app is open. (e.g. Messenger or WhatsApp). And would be destroyed when that app has been closed.
Here's my code-
#Override
public void onCreate() {
super.onCreate();
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
chatHead = new ImageView(this);
chatHead.setImageResource(R.drawable.view_icon);
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.START;
params.x = 0;
params.y = 100;
windowManager.addView(chatHead, params);
getForeground();
chatHead.setOnClickListener(new View.OnClickListener() {
/*.....
.....
ClickListener implemented
.....
.....
*/
});
}
Here, in the onCreate(), I'm calling the getForeground() method, which gets the current activity in the foreground
public String getForeground() {
final ActivityManager am = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
String foreground = am.getRunningTasks(1).get(0).topActivity.getPackageName();
if (foreground.equals("com.whatsapp")) {
if (chatHead==null)
onResume();
}
else
onDestroy();
new Thread() {
#Override
public void run() {
getForeground();
}
}.start();
return foreground;
}
Where, onResume() is-
public void onResume() {
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.START;
params.x = 0;
params.y = 100;
windowManager.addView(chatHead,params);
}
And onDestroy() is-
#Override
public void onDestroy() {
super.onDestroy();
if (chatHead != null)
windowManager.removeView(chatHead);
else
chatHead=null;
}
However, it shows an IllegalStateException as follows-
java.lang.IllegalArgumentException: View=android.widget.ImageView{41f07a28 V.ED..C. ......ID 0,0-93,99} not attached to window manager
at android.view.WindowManagerGlobal.findViewLocked(WindowManagerGlobal.java:370)
at android.view.WindowManagerGlobal.removeView(WindowManagerGlobal.java:299)
at android.view.WindowManagerImpl.removeView(WindowManagerImpl.java:79)
at automated.whatsapp.com.automatedtest.ChatHeadService.onDestroy(ChatHeadService.java:172)
at automated.whatsapp.com.automatedtest.ChatHeadService.getForeground(ChatHeadService.java:188)
at automated.whatsapp.com.automatedtest.ChatHeadService$3.run(ChatHeadService.java:194)
So, basically, it says that the chatHead is not attached to the WindowManager. How do I correct this error?
You can use try-catch around your window manager like this
try{
WindowManager?.removeView(view);
}catch(e:Exception){
Log.e(debug_tag, "view not found");
}
or can check windowtoken of view exist
if (view?.windowToken!=null) {
WindowManager?.removeView(view);
}
because when your view is not added or remove view later your windowmanager make a new exception
Not sure if this can help you but this is what I did:
#Override
protected void onUserLeaveHint() {
if (this.chatHead != null) {
this.runOnUiThread(new Runnable() {
#Override
public void run() {
((WindowManager) getApplicationContext().getSystemService(Service.WINDOW_SERVICE)).removeView(chatHead);
}
});
}
}
