android-button

I have some buttons which I set its background color as red, green and blue separately. When I press the button, click event is generated, but there is no change in gui for the user to know the button is pressed. Android button’s default background grayish color changes to orange and come back to grayish color after releasing the pressed state. How to implement this on colored button? That is implemented via a StateListDrawable , represented by selector in XML . Reference: http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList Here is an example of a drawable that

I am using selectableItemBackgroundBorderless to add a ripple to an ImageView . My expected behaviour would be to have a circular ripple, extending the views size. Unfortunately the ripple gets cropped by the view bounds. How can this issue be solved? Default state: Pressed state: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/nav_instruction_container" android:layout_width="match_parent" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_height="wrap_content" xmlns:tools="http://schemas.android.com/tools" android:background="

But when I apply a color as a background, it is getting bigger, even though I did not set a different width or height on it. This is my xml layout before I set background attribute to button <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <Button android:background="@color/white"

Good day, everyone! Today I got, as I suppose, very interesting question. On my job we are creating a dating service and one of the main features will be the screen, where photos of different girls( or guys) are shown and the user press either "Hot" or "Not" button. Both of these buttons are displayed below the photo on the screen. Our analytics say (god "bless" them...) that we should implement some kind of "gaming" mechanics, so the want such a thing: when user press, for example, "Not" button - it starts freezing and covering with ice, then it breaks and then the next photo is shown. That
