Android: Center position of the button (fill_parent, wrap_content)

<Button android:id="@+id/btClick" android:gravity="center_vertical|center_horizontal"

android:layout_width="fill_parent" - object have width like parent
android:layout_height="wrap_content" - parent height wants to be just big enough to enclose its content

 In your android phone are many beautiful icons.Here is the list: and here is more

To use: 
  • in recourses  android:icon="@android:drawable/<name of your element>"
  • in java code android.R.drawable.<name of your element>
But be aware:

Warning: Because these resources can change between platform versions, you should not reference these icons using the Android platform resource IDs (i.e. menu icons under android.R.drawable).
