Quite a long title, isn’t it? Smile

On-screen keyboard usually takes around half of the screen space while it’s shown. Most of the times it hides important controls/views that you want to be shown to the user all the times. Consider a layout having a EditText widget at the top, a list or some other control in the middle and some Buttons right at the bottom. While the user is writing text in the EditText view through on-screen keyboard, the buttons would be hiding behind it. Luckily, Android has an option to handle this scenario automatically without writing much code.

To enable a layout to adjust itself while the keyboard is shown, you need to configure an attribute for its host activity through AndroidManifest.xml file. Here’s how to do it:

<activity android:name="TestActivity" android:windowSoftInputMode="adjustResize" android:screenOrientation="portrait">

By setting android:windowSoftinputMode of this activity to adjustResize you are telling it to resize itself while the on-screen keyboard is shown. This will let the activity to shorten it’s layout in order to show everything that’s present over it. For example, if you have some buttons at the bottom of the screen, this setting will show them just above the keyboard helping the user to interact with them without closing the keyboard.

There’s one important catch in this however, this configuration DOES NOT work if the application is bound to run in full-screen. This is normally done by setting it’s android:theme attribute to @android:style/Theme.NoTitleBar.FullScreen in AndroidManifest.xml file.

This is one simple and neat technique to make your layout more flexible and user-friendly.
