Two ways to customize a control

First Type: Code

Setting_view.xml

<?xml version= "1.0" encoding= "Utf-8"?>

<relativelayout xmlns:android= "Http://schemas.android.com/apk/res/android"

Android:layout_width= "Match_parent"

android:layout_height= "55DP" >

<textview

Android:id= "@+id/tv_title"

Android:layout_width= "Wrap_content"

android:layout_height= "Wrap_content"

Android:text= "Attribution to display Settings"

Android:textsize= "20sp"/>

<textview

Android:id= "@+id/tv_content"

Android:layout_width= "Wrap_content"

android:layout_height= "Wrap_content"

android:layout_below= "@id/tv_title"

Android:text= "The place of attribution has been opened"

Android:textsize= "16sp"/>

<checkbox

Android:id= "@+id/cb_status"

Android:layout_width= "Wrap_content"

android:layout_height= "Wrap_content"

Android:layout_alignparentright= "true"

Android:layout_centerinparent= "true"

Android:checked= "true"/>

</RelativeLayout>

public class Mainactivity extends Activity {

@Override

protected void OnCreate (Bundle savedinstancestate) {

Super.oncreate (savedinstancestate);

Settingview SV = new Settingview (this);

Setcontentview (SV); }

}

public class Settingview extends Relativelayout {

Public Settingview (context context, AttributeSet attrs, int defstyle) {

Super (context, attrs, Defstyle);

Initui (context); }

Public Settingview (context context, AttributeSet Attrs) {

Super (context, attrs);

Initui (context); }

Public Settingview (Context context) {

Super (context);

Initui (context); }

private void Initui (context context) {

View view = view.inflate (context, r.layout.setting_view, null);

This.addview (view);//this refers to the object that invokes the AddView (view) method, which is the parameter context}

}

Second way: XML format
