自定义组合控件 设置选项

写一个条目

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="65dp" >    <TextView        android:id="@+id/tv_setting_title1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginLeft="10dp"        android:layout_marginTop="10dp"        android:text="自动更新应用"        android:textColor="#000000"        android:textSize="20sp" />    <TextView        android:id="@+id/tv_desc"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@id/tv_setting_title1"        android:layout_marginLeft="15dp"        android:text="自动更新已经关闭"        android:textColor="#88000000"        android:textSize="14sp" />    <CheckBox        android:id="@+id/setting_cb"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentRight="true"        android:layout_centerVertical="true"        android:clickable="false"    牺牲checkbox的点击 成全整个控件的点击        android:layout_marginRight="10dp" />    <View        android:layout_width="fill_parent"        android:layout_height="1px"        android:layout_alignParentBottom="true"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        android:background="#000000" /></RelativeLayout>

然后自定义一个控件 SettingItemView

package com.zbzbhahae.mobilesafe.ui;import com.zbzbhahae.mobilesafe.R;import android.content.Context;import android.util.AttributeSet;import android.view.View;import android.widget.CheckBox;import android.widget.RelativeLayout;import android.widget.TextView;/** * 自定义组合控件 有两个TextView 还有一个CheckBox 还有一个View * @author zbzbhahae * */public class SettingItemView extends RelativeLayout {private CheckBox cb_status;private TextView tv_desc;private TextView tv_title;private String desc_on;private String desc_off;/** * 初始化布局文件 * @param context */private void initView(Context context) {//布局文件转换成View 并且加载到SettingItemView中View.inflate(context, R.layout.item_setting_list, SettingItemView.this);cb_status = (CheckBox) this.findViewById(R.id.setting_cb);tv_desc = (TextView) this.findViewById(R.id.tv_desc);tv_title = (TextView) this.findViewById(R.id.tv_setting_title1);}public SettingItemView(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);initView(context);}public SettingItemView(Context context, AttributeSet attrs) {super(context, attrs);initView(context);String thetitle = attrs.getAttributeValue("http://schemas.android.com/apk/res/com.zbzbhahae.mobilesafe", "thetitle");//attrs中写的3个属性desc_on = attrs.getAttributeValue("http://schemas.android.com/apk/res/com.zbzbhahae.mobilesafe", "desc_on");desc_off = attrs.getAttributeValue("http://schemas.android.com/apk/res/com.zbzbhahae.mobilesafe", "desc_off");tv_title.setText(thetitle);}public SettingItemView(Context context) {super(context);initView(context);}/** * 校验组合空间是否选中 */public boolean isChecked() {return cb_status.isChecked();}/** * 设置组合控件的是否选中 */public void setChecked(boolean checked) {if(checked) {setDesc(desc_on);} else {setDesc(desc_off);}cb_status.setChecked(checked);}/** * 设置组合控件的描述信息 */public void setDesc(String text) {tv_desc.setText(text);}}

设置界面的布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:zbzbhahae="http://schemas.android.com/apk/res/com.zbzbhahae.mobilesafe"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:background="#FFFFFF" >    <TextView         android:layout_width="fill_parent"        android:layout_height="55dp"        android:text="设置中心"        android:gravity="center"        android:background="#8866FF00"        android:textColor="#000000"        android:textSize="30sp"        android:layout_gravity="center"/>        <com.zbzbhahae.mobilesafe.ui.SettingItemView        android:id="@+id/siv_update"        zbzbhahae:thetitle="设置自动更新"        zbzbhahae:desc_on="自动更新已经开启"        zbzbhahae:desc_off="自动更新已经关闭"        android:layout_width="wrap_content"        android:layout_height="wrap_content"/>        </LinearLayout>

zbzbhahae:thetitle="设置自动更新"        zbzbhahae:desc_on="自动更新已经开启"        zbzbhahae:desc_off="自动更新已经关闭"

上面3条需要在values/attrs中定义 线性布局中要添加命名空间

xmlns:zbzbhahae="http://schemas.android.com/apk/res/com.zbzbhahae.mobilesafe"

后面是自己应用的包名

attrs.xml:

<?xml version="1.0" encoding="utf-8"?><resources>    <declare-styleable name="TextView">        <attr name="thetitle" format="string"/>        <attr name="desc_on" format="string" />        <attr name="desc_off" format="string" />    </declare-styleable></resources>
