Here's a bit of code I've been playing with that may give you some
inspiration:
package com.example.floatingwindowtest;

private int Xdown, Xstart;
private int Ydown, Ystart;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
// System.exit(0);
Toast.makeText(getBaseContext(),"onCreate",
Toast.LENGTH_SHORT).show();
params = new
WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_PHONE,

WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH |
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, PixelFormat.TRANSLUCENT);
params.gravity=Gravity.TOP|Gravity.LEFT;
wm = (WindowManager) getSystemService(WINDOW_SERVICE);

wm.getDefaultDisplay().getMetrics(dm);
final int size = (int) ((double)dm.heightPixels/2.5);
params.x = (dm.widthPixels-size)/2;

inflateview();
foregroundNotification(1);
//moveToForeground(1,n,true);
}
@Override

getSystemService(NOTIFICATION_SERVICE)).cancel(0);
Toast.makeText(getBaseContext(),"onDestroy",

}
}

{

getSystemService(NOTIFICATION_SERVICE)).notify(id,
notification);
return notification;
}
private PendingIntent notificationIntent() {
Intent intent = new Intent(this, MainActivity.class);
PendingIntent pending = PendingIntent.getActivity(this, 0,
intent, PendingIntent.FLAG_UPDATE_CURRENT);
return pending;
}
public void inflateview()
{
LayoutInflater inflater = (LayoutInflater)
getSystemService(LAYOUT_INFLATER_SERVICE);
myView = inflater.inflate(R.layout.activity_popup, null);
myView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
// Toast.makeText(getBaseContext(),"ACTION_DOWN",

Xdown=(int) event.getRawX();

break;

FloatingWindowService.this.wm.updateViewLayout(myView, params);
break;
default:
break;
}
return true;
}
});
final Button OKButton = (Button)
myView.findViewById(R.id.OK_Button);
OKButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
FloatingWindowService.this.stopSelf();
}
});
// Drawable MyBG =
Drawable.createFromPath("content://media/external/images/media/100741");
// myView.setBackground(MyBG);
// Add layout to window manager
wm.addView(myView, params);
}
}
You need the permission <uses-permission
android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
Just add the appropriate layout file and if desired make it more like a
toast by adding a timer to automatically dismiss it after so many seconds.
