Android Phone development Control TextView Text Center _android

There are 2 ways to set the center of TextView text:

One: In the XML file settings: android:gravity= "center"

II: In the program set: Txttitle.setgravity (Gravity.center);

To set the center of a control:

Android:layout_gravity= "Center" is centered over the entire layout of the TextView control, or it can be invoked in its parent layout setting android:gravity= "Center"

The program is also the parent layout that needs to set its control, for example:

Relativelayout.layoutparams layoutparams= 
  New Relativelayout.layoutparams (RelativeLayout.LayoutParams.WRAP_ CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); 
Layoutparams.addrule (relativelayout.center_in_parent); 

In fact, it's easy to understand that "layout" is the control's action on the entire layout

Note: Set to center vertically, which you can set in XML

Android:gravity= "Center_vertical"
