How to center the horizontal text in TextView , ie center in the top and bottom line.
<TextView
android:id="@+id/txt"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="right"
android:text="Texto"/>
<TextView
android:id="@+id/txt"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="Texto"/>
In this way, you will center both horizontally and vertically. If you need only horizontally:
<TextView
android:id="@+id/txt"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:text="Texto"/>
Or programmatically:
seuTexview.setGravity(Gravity.CENTER);
More details can be found here at documentation android .
To be at the time of popular the field:
campo.setGravity(Gravity.CENTER_HORIZONTAL);
To return to the initial state
campo.setGravity(Gravity.NO_GRAVITY);
To set the left:
campo.setGravity(Gravity.LEFT);
To set the right:
campo.setGravity(Gravity.RIGHT);
