If you use an EditText with an input password type, you can also enable an icon that can show or hide the entire text using the passwordToggleEnabled attribute. NOTE: You must have support library 24.2.0 or higher to use this feature. These settings can also be defined dynamically through SetCounterEnabled() and SetCounterMaxLength(): The TextInputLayout simply needs to define app:counterEnabled and app:CounterMaxLength in the XML attributes. The counter will be rendered below the EditText and can change colors of both the line and character counter if the maximum number of characters has been exceeded: TextInputLayout since the announcement of support design library v23.1 also can expose a character counter for an EditText defined within it.
We can also use the TextInputLayout to display error messages using the SetError and SetErrorEnabled properties in the activity at runtime. Now the hint will automatically begin to float once the EditText takes focus as shown below: Note that the style does not use the android prefix. app:elevationĪ style is used to get the a borderless button. app:useCompatPaddingĬan be a string, integer, boolean, color value, floating point, dimension value.

Create another array to hold the values we want to return. The first one may be the simplest method, spinner1 in the example.Spinner with different display text and return value Sometimes, we want to display some meaningful text in Spinner (such as "Sunday", "Monday".), but return some other value when any item selected (such as 0, 2.). It will be the same object of the display items, as show in the spinner0 of the example. In the most basic Spinner implementation, selected item can be retrieved by calling parent.getItemAtPosition(position) in onItemSelected() method in OnItemSelectedListener.
