The soft keyboard is hidden when the user chooses the activity — that is, when the user affirmatively navigates forward to the activity, rather than backs into it because of leaving another activity.
1. In your AndroidManifest.xml file, add the following line between the <activity> tags of the Activity you would like to hide the soft keyboard.
android:windowSoftInputMode="stateHidden"
2. Compile and run!
