I would like to Disable Notification Bar using the en, but when i tried to put this code in my OnCreat method in the main Activity, i have some problem. I don't know what to put in <height of the status bar>, what is params i tried to put handleParams, i have the some problem and a problem using
context.getWindow().addView(view, params); is unkown and i can't use context.getWindow()
View disableStatusBar = new View(context);
WindowManager.LayoutParams handleParams = new WindowManager.LayoutParams(
WindowManager.LayoutParams.FILL_PARENT,
<height of the status bar>,
// This allows the view to be displayed over the status bar
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
// this is to keep button presses going to the background window
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,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP;
context.getWindow().addView(view, params);
Just add to your manifest:
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"

I'm showing a custom overlay with this parameter inflating the view from a service:
params = new WindowManager.LayoutParams(WindowManager
.LayoutParams
.MATCH_PARENT,
statusBarHeight, WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, WindowManager
.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
| WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE | WindowManager.LayoutParams
.FLAG_NOT_FOCUSABLE, 0);
params.gravity = Gravity.CENTER | Gravity.TOP;
The problem is that if the status bar is expanded, the overlay is over the quick settings menu. How can I avoid that? I'm using android 6.
Instead of TYPE_SYSTEM_OVERLAY use TYPE_SYSTEM_ERROR.
params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
100,
// Allows the view to be on top of the StatusBar
WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
// Keeps the button presses from going to the background window
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
// Enables the notification to recieve touch events
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
// Draws over status bar
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP|Gravity.CENTER;
mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
mWindowManager.addView(mView, mLP);
This should solve your issue.
I've a full screen application covering the entire screen, top status bar included.
Since a top / down swipe is enabled to show some options to the user, it happens that swiping from top to down, the status bar is showing (as when you want to see notifications and swipe top down).
Is there a way to avoid this ?
Use type TYPE_SYSTEM_ERROR for WindowManager.LayoutParams, to create hide impossible fullscreen view.
Swipes for show status bar and navigation will be blocked.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mMainLayout = (RelativeLayout) LayoutInflater.from(this).inflate(R.layout.activity_fullscreen, null);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
WindowManager.LayoutParams handleParams = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
PixelFormat.TRANSLUCENT);
handleParams.gravity = Gravity.TOP;
WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
windowManager.addView(mMainLayout, handleParams);
}
And you should be show it after display power on (unlock screen) if needs. Add code:
getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
There are a couple of options. Before the line
super.onCreate(savedInstanceState)
add the following:
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
This should completely get rid of the status bar. Basicaly the feature no title removes the top toolbar, and to ensure fullscreen size we are setting fullscreen flags for height and width.
As far as preventing from swiping at all, there is a trick that can be used. Basically place an invisible view at the top once you are in true fullscreen that prevents any swiping. For example,
View disableStatusBarView = new View(context);
WindowManager.LayoutParams handleParams = new WindowManager.LayoutParams(
WindowManager.LayoutParams.FILL_PARENT,
<height of the status bar>,
// This allows the view to be displayed over the status bar
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
// this is to keep button presses going to the background window
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,
PixelFormat.TRANSLUCENT);
handleParams.gravity = Gravity.TOP;
context.getWindow().addView(disableStatusBarView, handleParams);
This creates an invisible view over the status bar that will receive the touch events and block the events from reaching the status bar, therefore preventing it to be expanded.
Alternatively, and this works the best, is to override the windowFocusChanged method. Essentially you are NOT preventing the status bar from expanding, but YOU ARE preventing use. Because once expanded, it is closed. I say that this works best because with the invisible view methodology, you may want to consider the dimensions of the screen to really make it effective for all device. So there is more work.
First, declare permission in manifest
<uses-permission android:name="android.permission.EXPAND_STATUS_BAR"/>
Then Override onWindowFocusChanged method,
public void onWindowFocusChanged(boolean hasFocus)
{
try
{
if(!hasFocus)
{
Object service = getSystemService("statusbar");
Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
Method collapse = statusbarManager.getMethod("collapse");
collapse .setAccessible(true);
collapse .invoke(service);
}
}
catch(Exception ex)
{
}
}
I'm trying to make a custom navigation button and have disabled the default navigation buttons provided by android by rooting my device. I want my custom navigation buttons to disappear after some interval of time (say 5 seconds). I have managed to do so. I want to make something such that whenever I touch anywhere on the screen, I can detect the touch event and show my navigation bar. Whether I'm on homescreen or any application, I can receive touch event. Is there a way to do so or do I need to go android source code?
Thank you
OnCreate of your Service: used WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH flag.
#Override
public void onCreate() {
super.onCreate();
Toast.makeText(getBaseContext(),"onCreate", Toast.LENGTH_LONG).show();
mView = new HUDView(this);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.RIGHT | Gravity.TOP;
params.setTitle("Load Average");
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(mView, params);
}
Now, you will start getting each and every click event.
see this Creating a system overlay window (always on top)
I made a View in service which runs always on top of every application in android.
Initially, the behaviour of service is TYPE_SYSTEM_ALERT .
WindowManager.LayoutParams layparams = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
layparams .gravity = Gravity.CENTER_VERTICAL| Gravity.CENTER_HORIZONTAL;
wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(serviceView, layparams );
I am changing the behaviour of service at run time means switching between TYPE_SYSTEM_ALERT AND TYPE_SYSTEM_OVERLAY on touch. Switch take place when I touch outside the view parameters and when touch inside the view parameters.
layparams .type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;
Using updateViewLayout(serviceView, layparams )
PROBLEM: Is when I touch outside of view , the first touch just activate TYPE_SYSTEM_OVERLAY and after then outside app works fine. When TYPE_SYSTEM_OVERLAY is working , after that when you touch within the view it will trigger the action of object behind the view not the action of the view. But when u once touch the view TYPE_SYSTEM_ALERT will be applied and now the View will behave normally .
Current Implementation : I have to touch twice to work that particular thing when switch take place between layout parameters.
use this one... works perfectly on ICS and above
params.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;//This one is necessary.
params.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH |
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS;
params.gravity = Gravity.TOP | Gravity.RIGHT;
params.x = 0;
params.y = -params.height;
windowManager.addView(tile, params);
you can do this by calling updateViewLayout() on instance of WindowManager class.
wm = (WindowManager) getSystemService(WINDOW_SERVICE);
// create new layout params
WindowManager.LayoutParams newlayparams = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
//update new layout
wm.updateViewLayout(serviceView, newlayparams);
Hope it help!
I recently saw an image of an app that was capable of displaying a view above the status bar and was also able to cover it with a view.
I know you can get a view right below the status bar from a view with align parent top. But how would you get a view on top of the status bar??
Example
Disable the System Status Bar - Without Root
After two full days of searching through SO posts and reading the Android docs over and over.. Here is the solution that I came up with. (tested)
mView= new TextView(this);
mView.setText(".........................................................................");
mLP = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
100,
// Allows the view to be on top of the StatusBar
WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
// Keeps the button presses from going to the background window
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
// Enables the notification to recieve touch events
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
// Draws over status bar
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
PixelFormat.TRANSLUCENT);
mLP.gravity = Gravity.TOP|Gravity.CENTER;
mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
mWindowManager.addView(mView, mLP);
Dont forget the permissions:
<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />
Note:
Tested upto kitkat.
The answer by #Sadeshkumar is incorrect for ICS and above (perhaps GB as well).
A view created with TYPE_SYSTEM_ALERT and FLAG_LAYOUT_IN_SCREEN is covered by the StatusBar.
To get an overlay on top of the StatusBar, you need to use TYPE_SYSTEM_OVERLAY instead of TYPE_SYSTEM_ALERT.
The problem being then, how to get clicks/touches?
A view created with TYPE_SYSTEM_ERROR and FLAG_LAYOUT_IN_SCREEN is covered by the StatusBar.
int statusBarHeight = (int) Math.ceil(25 * getResources().getDisplayMetrics().density);
View statusBarView = new View(MyActivity.this);
statusBarView.setBackgroundColor(Color.GREEN);
WindowManager.LayoutParams params = null;
params = new WindowManager.LayoutParams(WindowManager.LayoutParams.FILL_PARENT,statusBarHeight,WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN, PixelFormat.TRANSLUCENT);
params.gravity = Gravity.RIGHT | Gravity.TOP;
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(statusBarView, params);
