I'm creating an app which should draw fullscreen overlay. Something like lockscreen. The user set some timer and when time is come this overlay should appear.
But overlay doesn't cover system navigation bar. It's a problem when navigation bar is semi-transparent. User can touch system buttons and can see some changeable background behind them. Thus user can see something behind the lock screen. It's a problem.
How could I prevent this situation?
Notice that lock screen overlay is not the activity. User sets timer and can browse his device freely. When the time comes the app draws some view over the screen, like this:
View overlayView = new OverlayView(this);
windowManager.addView(overlayView, OverlayView.createLayoutParams(retrieveScreenHeight()));
where
public OverlayView(Context context) {
super(context);
inflate(context, R.layout.overlay_view, this);
}
static WindowManager.LayoutParams createLayoutParams(int height) {
final WindowManager.LayoutParams params =
new WindowManager.LayoutParams(MATCH_PARENT, height, TYPE_SYSTEM_ERROR,
FLAG_NOT_FOCUSABLE
| FLAG_LAYOUT_IN_SCREEN
| FLAG_LAYOUT_NO_LIMITS
| FLAG_NOT_TOUCH_MODAL
| FLAG_LAYOUT_INSET_DECOR
| WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION
, TRANSLUCENT);
params.gravity = Gravity.TOP;
return params;
}
public int retrieveScreenHeight() {
int result = 0;
WindowManager wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);
Point outSize = new Point();
wm.getDefaultDisplay().getSize(outSize);
if(outSize.y > outSize.x){
result = outSize.y;
}else{
result = outSize.x;
}
return result;
}
I assume you'll want to make the activity that hosts the overlay view as fullscreen if you want to cover the system bar.
Something like below code.
public class ActivityName extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// remove title
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
Then your activity will not show the system bar, and you'll have your view going all the way to the top of the screen.
EDIT : From your last comment, here's how I'd do it :
Step 1 : Create this FullScreenLockActivity :
public class FullScreenLockActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// remove title
requestWindowFeature(Window.FEATURE_NO_TITLE);
// set to fullScreen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
//Load your black semi-transparent view
setContentView(R.layout.lock_screen);
}
//Override this to prevent the user to close this activity by pressing the back button
#Override
public void onBackPressed() {}
}
Step 2 : Implement your "unlock screen" behavior in the FullScreenLockActivity
Step 3 : To display the lock screen, call
Intent i = new Intent(yourCurrentActivity.this, FullScreenLockActivity.class);
startActivity(i);

Currently, we are figuring how to implement such a bottom sheet, with the following requirements.
Round corner bottom sheet.
Fixed height bottom sheet.
Non-draggable bottom sheet.
Content in the bottom sheet is scrollable.
Hide bottom sheet when we tap on non-bottom sheet item.
Hide sheet when we press on back button.
A non-blocking bottom sheet. When we tap on non-bottom sheet item, the tapped item will get focus and bottom sheet will hide.
We are considering, whether to use BottomSheetBehavior or BottomSheetDialogFragment.
So far, we manage to implement all the requirements, by using BottomSheetBehavior.
Implementation using BottomSheetBehavior
However, we do not really like the solution as
It increases the complexity of our Activity's layout, where additional CoordinatorLayout is required.
Manual touch event code handling is required at Activity, to achieve requirement 5, 6 & 7 (Hide bottom sheet).
Here's the code snippet by using BottomSheetBehavior.
public class MainActivity extends AppCompatActivity {
private BottomSheetBehavior bottomSheetBehavior;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.image_button_0).setOnClickListener(view -> demo0());
findViewById(R.id.image_button_1).setOnClickListener(view -> demo1());
// 7) A non-blocking bottom sheet. When we tap on non-bottom sheet item, the tapped item
// will get focus and bottom sheet will hide.
findViewById(R.id.edit_text_0).setOnFocusChangeListener((view, b) -> {
if (b) {
hideBottomSheet();
}
});
// 7) A non-blocking bottom sheet. When we tap on non-bottom sheet item, the tapped item
// will get focus and bottom sheet will hide.
findViewById(R.id.edit_text_1).setOnFocusChangeListener((view, b) -> {
if (b) {
hideBottomSheet();
}
});
}
public void demo0() {
DemoBottomDialogFragment demoBottomDialogFragment = DemoBottomDialogFragment.newInstance();
demoBottomDialogFragment.show(getSupportFragmentManager(), "demoBottomDialogFragment");
}
public void demo1() {
// 1) Round corner bottom sheet.
View view = findViewById(R.id.bottom_sheet_layout_2);
/*
2) Fixed height bottom sheet.
3) Non-draggable bottom sheet.
4) Content in the bottom sheet is scrollable.
*/
this.bottomSheetBehavior = BottomSheetBehavior.from(view);
bottomSheetBehavior.setPeekHeight(900, true);
bottomSheetBehavior.setDraggable(false);
}
private boolean hideBottomSheet() {
if (this.bottomSheetBehavior != null) {
this.bottomSheetBehavior.setPeekHeight(0, true);
this.bottomSheetBehavior = null;
return true;
}
return false;
}
#Override
public void onBackPressed() {
// 5) Hide bottom sheet when we tap on non-bottom sheet item.
if (hideBottomSheet()) {
return;
}
super.onBackPressed();
}
#Override
public boolean onTouchEvent(MotionEvent event) {
// 6) Hide sheet when we press on back button.
hideBottomSheet();
return super.onTouchEvent(event);
}
}
If we were using BottomSheetDialogFragment, the code will be way more simpler. We can achieve all requirements, except number 7
A non-blocking bottom sheet. When we tap on non-bottom sheet item, the tapped item will get focus and bottom sheet will hide.
Here's the outcome of BottomSheetDialogFragment.
Implementation using BottomSheetDialogFragment
The good thing of using BottomSheetDialogFragment is that,
Will not increase the complexity of Activity's layout.
No code required at Activity, to hide the bottom sheet (Requirement 5, 6. Requirement 7 still not achievable)
Here's the code snippet.
public class DemoBottomDialogFragment extends BottomSheetDialogFragment {
public static DemoBottomDialogFragment newInstance() {
return new DemoBottomDialogFragment();
}
#NonNull
#Override public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
// https://stackoverflow.com/questions/58651661/how-to-set-max-height-in-bottomsheetdialogfragment
dialog.setOnShowListener(new DialogInterface.OnShowListener() {
#Override public void onShow(DialogInterface dialogInterface) {
BottomSheetDialog bottomSheetDialog = (BottomSheetDialog) dialogInterface;
FrameLayout bottomSheet = bottomSheetDialog.findViewById(com.google.android.material.R.id.design_bottom_sheet);
ViewGroup.LayoutParams layoutParams = bottomSheet.getLayoutParams();
// !!!
layoutParams.height = 900;
bottomSheet.setLayoutParams(layoutParams);
}
});
return dialog;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Make the bottom sheet non drag-able.
setStyle(DialogFragment.STYLE_NORMAL, R.style.BottomSheetDialogStyle);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater,
#Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.bottom_sheet_layout, container,
false);
// get the views and attach the listener
return view;
}
}
I was wondering, if we were using BottomSheetDialogFragment, is there a way to achieve
A non-blocking bottom sheet. When we tap on non-bottom sheet item, the tapped item will get focus and bottom sheet will hide.
As you can see, when I tap on EditText region, the bottom sheet is hidden. But, the EditText is not getting focus.
Here's the complete workable demo for testing purpose - https://github.com/yccheok/wediary-sandbox/tree/master/bottom-sheet
Thank you.
There are two window flags that allow passing touch events to the background windows:
FLAG_NOT_TOUCH_MODAL
FLAG_WATCH_OUTSIDE_TOUCH
But those flags can work only for touches outside the dialog window; so setting them alone won't work if the dialog window expands to obscure the EditText's.
So, we need to limit the dialog window to the bottom sheet desired layout height which it's hard coded as 900px. Doing this can prevent the window from obscuring the EditText's; and hence the flags do their job.
Now, we'll hard code the window height to that value; and set the bottom sheet to the expanded state to expand to the entire window:
So, instead of layoutParams.height = 900; We'd use:
WindowManager.LayoutParams params = window.getAttributes();
params.height = 900;
params.gravity = Gravity.BOTTOM; // bias the dialog to the bottom
getDialog().getWindow().setAttributes(params);
This will achieve the desired behavior but now the rounded corners are gone as the expanded state is designed to expand to the entire available space. To solve this we'd set the rounded corner in the BottomSheet style instead of the layout.
Here is the modified version:
<resources>
<style name="BottomSheetDialogStyle" parent="Theme.Material3.Light.BottomSheetDialog">
<item name="behavior_draggable">false</item>
<item name="bottomSheetStyle">#style/BottomSheetStyle</item>
</style>
<style name="BottomSheetStyle">
<item name="android:background">#drawable/bottom_sheet_background</item>
</style>
</resources>
Now we can safely remove android:background="#drawable/bottom_sheet_background" from the layout.

public class DemoBottomDialogFragment extends BottomSheetDialogFragment {
public static DemoBottomDialogFragment newInstance() {
return new DemoBottomDialogFragment();
}

I am trying to overlap system bottom navigation bar using window manager but i can`t do it. I am Using bellow code.I have set gravity to bottom, therefore it show view layer in bottom of my activity view not not overlapping bottom navigation bar.
public void onCreate(Bundle savedInstancestate)
{
super.onCreate(savedInstancestate);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);7
manager = ((WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE));
localLayoutParams = new WindowManager.LayoutParams();
localLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;
localLayoutParams.gravity = Gravity.BOTTOM;
localLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|
// this is to enable the notification to recieve touch events
//WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN |
//WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH |
// Draws over navigation bar
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
//localLayoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
localLayoutParams.height = (int) (50 * getResources().getDisplayMetrics().scaledDensity);
localLayoutParams.format = PixelFormat.TRANSPARENT;
view = new customView(this);
manager.addView(view, localLayoutParams);
setContentView(R.layout.Imges);
}
public class customView extends ViewGroup {
public customView(Context context) {
super(context);
}
#Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
Log.v("customView", "------Intercepted-------");
return true;
}
}
Using this code i can't overlap navigation,Its shows new custom view in bottom of my activity view but can not overlap navigation bar with custom view.
any one can help me on this, to overlap navigation bar with custom view.?
There are actually some solutions.You cannot overlap in the means of making it totally disappear since there are devices in market without the hardware buttons. However you can elegantly arrange your layout accordingly.
For example,
Add this to your styles.xml (v21 )in a values dir:
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
or if it does not work,
boolean hasMenuKey = ViewConfiguration.get(getContext()).hasPermanentMenuKey();
boolean hasBackKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_BACK);
if(!hasMenuKey && !hasBackKey) {
// Do whatever you need to do, this device has a navigation bar
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(
FrameLayout.LayoutParams.MATCH_PARENT,
FrameLayout.LayoutParams.MATCH_PARENT
);
params.setMargins(0, 0, 0, 75);
entrancelayout.setLayoutParams(params);
entrancelayout.requestLayout();
}
I had a FrameLayout, you can use it for whatever layout you have. SetMargins adds margin to buttom in example. It assumes System Bar is there if there are no hardware back and menu buttons.
Is there a way on android to keep the status bar while disabling all interaction you can do with it, like pulling it down?
I want to keep the information this bar gives, but I don't want users to interact with it.
This is the method that I like to use. You can unwrap it from the method and place it inside a base Activity instead. iirc, I got this from StackOverflow as well, but I didn't make a note of it so I'm not sure where the original post is.
What it basically does is place a transparent overlay over the top bar that intercepts all touch events. It's worked fine for me thus far, see how it works for you.
You MAY need to put this line in the AndroidManifest:
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
I have it in my project, but I can't remember if it's because of this or something else. If you get a permission error, add that in.
WindowManager manager;
CustomViewGroup lockView;
public void lock(Activity activity) {
//lock top notification bar
manager = ((WindowManager) activity.getApplicationContext()
.getSystemService(Context.WINDOW_SERVICE));
WindowManager.LayoutParams topBlockParams = new WindowManager.LayoutParams();
topBlockParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
topBlockParams.gravity = Gravity.TOP;
topBlockParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|
// this is to enable the notification to recieve touch events
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
// Draws over status bar
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
topBlockParams.width = WindowManager.LayoutParams.MATCH_PARENT;
topBlockParams.height = (int) (50 * activity.getResources()
.getDisplayMetrics().scaledDensity);
topBlockParams.format = PixelFormat.TRANSPARENT;
lockView = new CustomViewGroup(activity);
manager.addView(lockView, topBlockParams);
}
and CustomViewGroup is
private class CustomViewGroup extends ViewGroup {
Context context;
public CustomViewGroup(Context context) {
super(context);
this.context = context;
}
#Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
Log.i("StatusBarBlocker", "intercepted by "+ this.toString());
return true;
}
}
Also! You also have to remove this view when your activity ends, because I think it will continue to block the screen even after you kill the application. Always, always ALWAYS call this onPause and onDestroy.
if (lockView!=null) {
if (lockView.isShown()) {
//unlock top
manager.removeView(lockView);
}
}
I need to enable full screen mode without navigation bar on android which placed in the bootom of the screen. (Like on clash of clans game).
I don't know how can I do this in cocos2dx. Kindly suggest.
if your question about android then that is the answer
public class FullScreen extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
if you want full screen For window (Ex: web view .....)
int width = [[NSScreen mainScreen] frame].size.width;
int height = [[NSScreen mainScreen] frame].size.height;
[yourWindow setFrame:NSMakeRect(0, 0, width, height) display:YES];
You can refer to some tutorial teach you how make your window full screen

I am implementing a kiosk mode application and i have successfully made the application full-screen without status bar appearance post 4.3 but unable to hide status bar in 4.3 and 4.4 as status-bar appears when we swipe down at the top of the screen.
I have tried to make it full screen by
speciflying the full screen theme in manifest
setting window Flags ie setFlags
setSystemUiVisibility
Possible duplicate but no concrete solution found
Permanently hide Android Status Bar
Finally the thing i want is, how to hide status bar permanently in an activity?? in android 4.3,4.4,5,6versions
We could not prevent the status appearing in full screen mode in kitkat devices, so made a hack which still suits the requirement ie block the status bar from expanding.
For that to work, the app was not made full screen. We put a overlay over status bar and consumed all input events. It prevented the status from expanding.
note:
customViewGroup is custom class which extends any
layout(frame,relative layout etc) and consumes touch event.
to consume touch event override the onInterceptTouchEvent method of
the view group and return true
Updated
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
customViewGroup implementation
Code :
WindowManager manager = ((WindowManager) getApplicationContext()
.getSystemService(Context.WINDOW_SERVICE));
WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams();
localLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
localLayoutParams.gravity = Gravity.TOP;
localLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|
// this is to enable the notification to recieve touch events
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
// Draws over status bar
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
localLayoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
localLayoutParams.height = (int) (50 * getResources()
.getDisplayMetrics().scaledDensity);
localLayoutParams.format = PixelFormat.TRANSPARENT;
customViewGroup view = new customViewGroup(this);
manager.addView(view, localLayoutParams);
In Android M you have to get an extra permission for making overlays. android.permission.SYSTEM_ALERT_WINDOW is not enough! So I used the code from the answer of Abhimaan within disableStatusBar() and had to make an intent to open the right settings dialog. I also added removing view in onDestroy() in order to enable status bar when the app exits. I also reduced the overlay height to 40 as it seems to be enough. Code works with 5.1 and 6.0 here.
public static final int OVERLAY_PERMISSION_REQ_CODE = 4545;
protected CustomViewGroup blockingView = null;
#Override
protected void onDestroy() {
super.onDestroy();
if (blockingView!=null) {
WindowManager manager = ((WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE));
manager.removeView(blockingView);
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!Settings.canDrawOverlays(this)) {
Toast.makeText(this, "Please give my app this permission!", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, OVERLAY_PERMISSION_REQ_CODE);
} else {
disableStatusBar();
}
}
else {
disableStatusBar();
}
}

if (requestCode == OVERLAY_PERMISSION_REQ_CODE) {
if (!Settings.canDrawOverlays(this)) {

}
else
{ disableStatusBar();
}
}
}
protected void disableStatusBar() {
WindowManager manager = ((WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE));
WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams();
localLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
localLayoutParams.gravity = Gravity.TOP;
localLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
// this is to enable the notification to receive touch events
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
// Draws over status bar
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
localLayoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
localLayoutParams.height = (int) (40 * getResources().getDisplayMetrics().scaledDensity);
localLayoutParams.format = PixelFormat.TRANSPARENT;
blockingView = new CustomViewGroup(this);
manager.addView(blockingView, localLayoutParams);
}
For a project I worked on I had found a solution for this but it took a long time. Various threads on Stackoverflow and elsewhere helped me to come up with it. It was a work around on Android M but it worked perfectly. As someone asked for it so I thought I should post it here if it can benefit anyone.
Now that its been a while, I don't remember all the details, but the CustomViewGroup is the class which overrides the main ViewGroup, and detects that a user has swiped from top to show the status bar. But we didn't want to show it, so the user's intercept was detected and any further action was ignored, i.e. Android OS won't get a signal to open the hidden status bar.
And then the methods to show and hide the status bar are also included which you can copy/paste as is in your code where you want to show/hide the status bar.
/**
* This class creates the overlay on the status bar which stops it from expanding.
