Android TextView Text Center and vertical left center

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: M_txttitle.setgravity (Gravity.center);

Note: The difference between android:gravity and Android:layout_gravity is that the former operates inside the control, and the latter is the entire control.

For example:

The code is as follows	Copy Code
Android:gravity= "Center" is centered on the text in TextView Android:layout_gravity= "Center" is centered on the TextView control throughout the layout

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

TextView text is centered vertically on the left,

Set android:gravity= "Center_vertical|left".

android:gravity= "center", vertically horizontally

LinearLayout has two very similar properties: Android:gravity and Android:layout_gravity. The difference is that android:gravity is used to set the alignment of the view component, and android:layout_gravity is used to set the alignment of the container component.

For example, we can set android:gravity= "center" to center the text in the EditText in the EditText component, and we set the EditText android:layout_gravity= " Right "to have the EditText component centered in the LinearLayout.

code is as follows	copy code
< TextView     android:layout_width= "fill_parent"     android:layout_height= " Wrap_content "     android:textsize=" 40sp "     android:gravity=" Center_ Vertical|left "     android:text=" @string/hello_world "/>
