I finally managed to create a SIMPLE widget (1x1 cell) with ONE button that does something. In my case (for now) a toast. This was actually quite hard to do. Widgets work different from normal app's.

My code so far of all important files:

QUESTION 1:

I have a normal BUTTON, with a background. I have a @drawable/...xml on that button which defines the different images for normal and pressed state. This works quit nicely. Since toggleButton isnt supported on WIDGETS i had to use 'Button', but i want the effect of the toggle button. So after a button click the pressed state must be fixed/freezed! after another click the normal state should me fixed/freezed. How do you do this?



QUESTION 2:

If question 1 works: i need different actions on normal and pressed state. I would like to lower/increase the brightness of the screen.

In an app i created this worked:

    WindowManager.LayoutParams lp = getWindow().getAttributes();
    Toast.makeText(getBaseContext(),"Low brightness",Toast.LENGTH_LONG).show();
    lp.screenBrightness = 0.004F;
    float BackLightValue = lp.screenBrightness;
    int SysBackLightValue = (int)(BackLightValue * 255);
    android.provider.Settings.System.putInt(getContentResolver(),android.provider.Settings.System.SCREEN_BRIGHTNESS,SysBackLightValue);             
    getWindow().setAttributes(lp);

How do implement this in a widget?

I believe I'm almost done with this widget, but need a hand on these two questions.

Thanks!

Din't understand your first question but for the second question , you can create an activity that has no UI and write the above code to set the brightness.Use an intent to call this activity and share the data between them.

  • Ankur_gaur, thank you for your reply. ToggleButtons are not supported in widgets.. please read the docs about this. So to get the effect of a togglebutton, i want to use a button and freeze/hold the hover and normal states. So it will look like a toggle button. How do i do this? Not valid code, but to get the idea.. something like: http://paste2.org/p/2463312 – user1688558 Nov 11 '12 at 13:21
