public class SettingItemClickView extends RelativeLayout {

private TextView tvTitle;
private TextView tvDesc;

public SettingItemClickView(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
initView();
}

public SettingItemClickView(Context context, AttributeSet attrs) {
super(context, attrs);

public SettingItemClickView(Context context) {
super(context);
initView();
}

/**
* 初始化布局
*/
private void initView() {
View child = View.inflate(getContext(),
R.layout.setting_item_click_view, null);// 初始化组合控件布局

tvTitle = (TextView) child.findViewById(R.id.tv_title);
tvDesc = (TextView) child.findViewById(R.id.tv_desc);

this.addView(child);// 将布局添加给当前的RelativeLayout对象
}

/**
* 设置标题
*
* @param title
*/
public void setTitle(String title) {
tvTitle.setText(title);
}

/**
* 设置表述
*
* @param desc
*/
public void setDesc(String desc) {
tvDesc.setText(desc);
}
}

1、对自定义控件进行代码填充

sicLocation = (SettingItemClickView) findViewById(R.id.sic_location);

sicLocation.setTitle(“归属地提示框位置”);

sicLocation.setDesc(“设置归属地提示框的显示位置”);

2、在values的attrs中设置组合布局属性

（1）定义

<?xml version="1.0" encoding="utf-8"?>
<resources>

<declare-styleable name="SettingItemView">
<attr name="title" format="string" />
<attr name="desc_on" format="string" />
<attr name="desc_off" format="string" />
</declare-styleable>

</resources>

（2）引用 activity_setting.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:itheima="http://schemas.android.com/apk/res/com.itheima.mobilesafe66"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<TextView
android:id="@+id/textView1"
style="@style/TitleStyle"
android:text="设置中心" />

<com.itheima.mobilesafe66.view.SettingItemView
android:id="@+id/siv_update"
android:layout_width="match_parent"
android:layout_height="wrap_content"
itheima:desc_off="自动更新已关闭"
itheima:desc_on="自动更新已开启"
itheima:title="自动更新设置" />
