i cant get this code working in my mainactivity.
i have a working application and its mianactivity calls to webview and application continue to work in webview.
Now i want to make login screen as the topmost using windowmanager.
please help me with you have any sample code.
i want to do this minimum change to system.
Add These Lines before addin view
params.gravity = Gravity.TOP; //Initially view will be added to top
params.x = 0;
params.y = 0;

Is there a way to block touch on ANY application from a service? I've been thinking about getWindow(), but that is impossible in service. Also, I've been thinking about getting current activity and then use getWindow(). I hope you get the point of what am I tried to achieve.
Thanks to David Medenjak I have managed to solve the problem. This solution is working on Android APIs below 23 and it's going to make the screen black and block touches until you longpress on the screen.
WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
ImageView black = new ImageView(this);
black.setImageResource(R.drawable.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_NOT_TOUCH_MODAL,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;
params.y = 0;
windowManager.addView(black, params);
black.getLayoutParams().height = windowManager.getDefaultDisplay().getHeight();
black.getLayoutParams().width = windowManager.getDefaultDisplay().getWidth();
black.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
return false;
}
});
Here is the code for adding WindowManager to stay on top of other views.
private View mainView;
private WindowManager.LayoutParams params;
windowManager = (WindowManager) getSystemService(Service.WINDOW_SERVICE);
params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_FULLSCREEN,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;
params.y = 0;
windowManager.addView(mainView, params);
It works fine. Inflating a layout inside the window manager and updating the layout dynamically. But I am unable to update the view.
LayoutInflater inflater = LayoutInflater.from(CallTimerService.this);
mainView = inflater.inflate(R.layout.call_dialog, null);
callerNameTv = (TextView) mainView.findViewById(R.id.caller_name);
callerNameTv.setText(name);
setText method is called and there is no exception but the view is not updated. Can anyone point out the issue here?
Update the specific view you wish to modify:
// Get the view params
WindowManager.LayoutParams paramNameTV = (WindowManager.LayoutParams) callerNameTv .getLayoutParams();
//update the view layout
windowManager.updateViewLayout(callerNameTv, paramNameTV);
I am writing an android library that needs to display an activity on top of the client app. After some reading up it seems that adding a new window is what I want to do so I added in this permission.
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
I then try to add an image view by doing this
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.BOTTOM | Gravity.LEFT;
params.x = 10;
params.y = 100;
ImageView imageview = new ImageView(this);
imageview.setImageResource(R.drawable.avatar);
windowManager.addView( imageview , params);
But what I want is to have my own activity on this new window on top of the client apps window. is this even possible? How would I do this?
Ok the correct approach to this appears to be to inflate the layout with in the service class and add it to the windowmanager that way. Then create a regular java class that can be used as the event listeners for the actions within that layout. I didnt need to use fragments or activities.
mRootLayout = (LinearLayout) LayoutInflater.from(context).
inflate(R.layout.myContainerXML, null);
MyListManager myListManager = new MyListManager(mRootLayout,context);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
PixelFormat.TRANSLUCENT);
ListView listView = (ListView) mRootLayout.findViewById(R.id.listView);
final MyListAdapter adapter = new MyListAdapter(activity,R.layout.list_row,(ArrayList)myListManager.getList());
listView.setAdapter(adapter);
windowManager.addView(mRootLayout, params);
If anyone has a better way I would love to hear it thanks
When user start the application, I just want to show a button. User can continiue to use phone .
Example : (problem is icon is not clickable)
android:theme="#android:style/Theme.Translucent.NoTitleBar.Fullscreen"
http://developer.android.com/reference/android/Manifest.permission.html#SYSTEM_ALERT_WINDOW
"android.permission.SYSTEM_ALERT_WINDOW" use this permission in main-feast
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
Button btn = new ImageView(this);
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);
windowManager.addView(btn, params);
I want to implement notifications like the one in the following image.
Notification appears any time. I think it's of course a background service waiting for new messages from the server then shows this. What I think this is an activity implemented as dialog with this custom UI. Am I correct? And is it a normal startActivity method from the service? And how do I do the transition animation to make it appears slowly from left to right with zooming when show up?
Check out this link http://www.piwai.info/chatheads-basics. He provides information about how to add them on your screen.
The trick is to add a View to the WindowManager like following code
private WindowManager windowManager;
private ImageView chatHead;
public void addView()
{
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
chatHead = new ImageView(this);
chatHead.setImageResource(R.drawable.android_head);
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(chatHead, params);
}
Don't forget to add the permission <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
