Android

步骤：

• 1 自定义组合控件的布局settint_view.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_marginTop="10dp"android:gravity="center_vertical"><TextViewandroid:id="@+id/title_tv"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginLeft="15dp"android:layout_marginTop="5dp"android:text="自动更新"/><TextViewandroid:id="@+id/des_tv"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_below="@id/title_tv"android:layout_marginTop="5dp"android:layout_marginLeft="15dp"android:text="自动更新关闭"android:textSize="10dp"android:textColor="#dedcdc"/><!--该控件不支持点击事件，且不能获取焦点--><CheckBoxandroid:id="@+id/checkbox"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginRight="10dp"android:checked="true"android:layout_alignParentRight="true"android:clickable="false"android:focusable="false"/><Viewandroid:layout_width="match_parent"android:layout_height="1dp"android:background="#36000000"android:layout_marginTop="5dp"android:layout_below="@id/des_tv"/>
</RelativeLayout>

• 2 创建一个自定义子和控件的类SettingView.java

package com.nlte.phonesafe.com.nlte.phonesafe.view;import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.CheckBox;
import android.widget.LinearLayout;
import android.widget.TextView;import com.nlte.phonesafe.R;
import com.nlte.phonesafe.com.nlte.phonesafe.utils.CacheUtil;
import com.nlte.phonesafe.com.nlte.phonesafe.utils.LogUtil;/**自定义组合控件* Created by NLTE on 2016/3/22 0022.*/
public class SettingView extends LinearLayout {private TextView mTitleTv;//标题文本控件private TextView mDesTv;//描述private CheckBox mCheckBox;//复选框private View rootView;//组合自定义控件界面根节点对象private String title;private String des_on;private String des_off;/*1 把自定义组合控件的xml文件实例化为对象，并且添加到当前对象中，作为当前控件的子控件*//*2 自定义方法：操纵组合控件的自控件*/public SettingView(Context context) {super(context);init();}//布局xml实例化调用public SettingView(Context context, AttributeSet attrs) {super(context, attrs);init();//通过命名空间和属性名来获取属性值title = attrs.getAttributeValue("http://schemas.android.com/apk/res-auto","setting_title");des_on = attrs.getAttributeValue("http://schemas.android.com/apk/res-auto","setting_des_on");des_off = attrs.getAttributeValue("http://schemas.android.com/apk/res-auto","setting_des_off");//初始化自定义控件属性值mTitleTv.setText(title);if (CacheUtil.getBoolean(context, CacheUtil.APK_UPDATE)){mCheckBox.setChecked(true);mDesTv.setText(des_on);}else {mCheckBox.setChecked(false);mDesTv.setText(des_off);}}public SettingView(Context context, AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);init();}/*初始化自定义组合控件界面*/private void init() {rootView = View.inflate(getContext(), R.layout.setting_view, this);mCheckBox = (CheckBox)rootView.findViewById(R.id.checkbox);mTitleTv = (TextView)rootView.findViewById(R.id.title_tv);mDesTv = (TextView)rootView.findViewById(R.id.des_tv);}/*自定义方法*///设置组合控件标题public void setTitle(String title){mTitleTv.setText(title);}//设置组合控件描述public void setDes(String des){mDesTv.setText(des);}//设置组合控件复选框public void setChecked(boolean isChecked){mCheckBox.setChecked(isChecked);if (isChecked){mDesTv.setText(des_on);}else {mDesTv.setText(des_off);}}//取得组合控件的状态public boolean getChecked(){return mCheckBox.isChecked();}
}

• 3 自定义组合控件的属性
  -- 3.1 创建自定义属性/values/attrs.xml

<?xml version="1.0" encoding="utf-8"?>
<resources><declare-styleable name="SettingView"><attr name="setting_title" format="string"/><attr name="setting_des_on" format="string"/><attr name="setting_des_off" format="string"/></declare-styleable>
</resources>

-- 3.2 在xml中调用自定义的组合控件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"xmlns:app="http://schemas.android.com/apk/res-auto"android:orientation="vertical"tools:context="com.nlte.phonesafe.SettingActivity"><TextViewandroid:layout_width="match_parent"android:layout_height="60dp"android:gravity="center"android:textSize="20sp"android:background="#8b71ef9d"android:text="设置中心"/><com.nlte.phonesafe.com.nlte.phonesafe.view.SettingViewandroid:id="@+id/update_sv"android:layout_width="match_parent"android:layout_height="wrap_content"app:setting_title="自动升级"app:setting_des_on="自动升级开启"app:setting_des_off="自动升级关闭" /><com.nlte.phonesafe.com.nlte.phonesafe.view.SettingViewandroid:id="@+id/soft_sv"android:layout_width="match_parent"android:layout_height="wrap_content"app:setting_title="软件锁"app:setting_des_on="软件锁开启"app:setting_des_off="软件锁关闭" /></LinearLayout>

• 4 对控件的调用SettingActivity.java

package com.nlte.phonesafe;import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.TextView;import com.nlte.phonesafe.com.nlte.phonesafe.utils.CacheUtil;
import com.nlte.phonesafe.com.nlte.phonesafe.view.SettingView;public class SettingActivity extends AppCompatActivity {private Context context;private SettingView mUpdateSv;private SettingView mSoftLockSv;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_setting);context = this;mUpdateSv = (SettingView)findViewById(R.id.update_sv);mSoftLockSv = (SettingView)findViewById(R.id.soft_sv);//设置自动升级自定义点击监听事件 每一次点击切换复选状态mUpdateSv.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {if (mUpdateSv.getChecked()){CacheUtil.putBoolean(context, CacheUtil.APK_UPDATE, false);mUpdateSv.setChecked(false);}else {CacheUtil.putBoolean(context, CacheUtil.APK_UPDATE, true);mUpdateSv.setChecked(true);}}});//对软件锁的点击事件mSoftLockSv.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {if (mSoftLockSv.getChecked()){mSoftLockSv.setChecked(false);}else {mSoftLockSv.setChecked(true);}}});}
}
