Set gravity of a View Programmatically

Question

Im working on a View over Android Source Code. I was wondering how can we setup multiple gravities, to a custom View

This is the XML

<com.android.systemui.statusbar.policy.Clock         android:id="@+id/clock"         android:textAppearance="@style/TextAppearance.StatusBar.Clock"         android:layout_width="wrap_content"         android:layout_height="match_parent"         android:singleLine="true"         android:paddingLeft="6dip"         android:gravity="center_vertical|left"         /> 

As you see, default gravity is center_vertical|left, so my Java code should be something like this

    View clock = mStatusBarView.findViewById(R.id.clock);      if (clock != null) {         SOMEHOW SET GRAVITY -> mCenterClock ? Gravity.CENTER : (Gravity.CENTER_VERTICAL | Gravity.LEFT);     } 

setGravity method don't work on View. So is there an alternative of setting gravity without losing the width and height by default?.

Thanks in advance.

Answer 1

Since com.android.systemui.statusbar.policy.Clock extends TextView just cast it to a TextView and set the gravity.

 TextView clock = (TextView) mStatusBarView.findViewById(R.id.clock);  clock.setGravity(mCenterClock ? Gravity.CENTER : (Gravity.CENTER_VERTICAL | Gravity.LEFT)); 

Ref: Source code

Answer 2

Have you tried?

clock.setGravity(Gravity.CENTER | Gravity.CENTER_VERTICAL); 

Edit:

Since you cannot use setGravity for a plain View, do something like this,

You can use a RelativeLayout and set a rule like this...

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT); params.addRule(RelativeLayout.CENTER_HORIZONTAL|RelativeLayout.CENTER_IN_PARENT, clock.getId());
