Mettere un layout in overlay

Dopo aver predisposto windowManager e i WindowManager.LayoutParams si istanzia un Layout e si aggiunge alla finestra.

    @Override
    public int onStartCommand(Intent intent, int flags, int startId){

        windowManager=(WindowManager)getSystemService(WINDOW_SERVICE);
        WindowManager.LayoutParams wParams=new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.TYPE_PHONE,
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
                PixelFormat.TRANSLUCENT
        );
        
        newLayout=new RelativeLayout(this);
        windowManager.addView(newLayout,wParams);

.....

E quindi si inflata il layout voluto al posto di quello già messo.

        LayoutInflater layoutInflater=(LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
        layoutInflater.inflate(R.layout.layout,newLayout);

Ecco il tutto:

    @Override
    public int onStartCommand(Intent intent, int flags, int startId){

        windowManager=(WindowManager)getSystemService(WINDOW_SERVICE);
        WindowManager.LayoutParams wParams=new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.TYPE_PHONE,
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
                PixelFormat.TRANSLUCENT
        );

        newLayout=new RelativeLayout(this);
        windowManager.addView(newLayout,wParams);

        LayoutInflater layoutInflater=(LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
        layoutInflater.inflate(R.layout.layout,newLayout);



        return START_NOT_STICKY;
    }
