Android
步驟:
1 自定義組合控件的布局
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="自動更新"/><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="自動更新關閉"android:textSize="10dp"android:textColor="#dedcdc"/><!--該控件不支持點擊事件,且不能獲取焦點--><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 創建一個自定義子和控件的類
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;/**自定義組合控件* Created by NLTE on 2016/3/22 0022.*/
public class SettingView extends LinearLayout {private TextView mTitleTv;//標題文本控件private TextView mDesTv;//描述private CheckBox mCheckBox;//復選框private View rootView;//組合自定義控件界面根節點對象private String title;private String des_on;private String des_off;/*1 把自定義組合控件的xml文件實例化為對象,并且添加到當前對象中,作為當前控件的子控件*//*2 自定義方法:操縱組合控件的自控件*/public SettingView(Context context) {super(context);init();}//布局xml實例化調用public SettingView(Context context, AttributeSet attrs) {super(context, attrs);init();//通過命名空間和屬性名來獲取屬性值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");//初始化自定義控件屬性值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();}/*初始化自定義組合控件界面*/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);}/*自定義方法*///設置組合控件標題public void setTitle(String title){mTitleTv.setText(title);}//設置組合控件描述public void setDes(String des){mDesTv.setText(des);}//設置組合控件復選框public void setChecked(boolean isChecked){mCheckBox.setChecked(isChecked);if (isChecked){mDesTv.setText(des_on);}else {mDesTv.setText(des_off);}}//取得組合控件的狀態public boolean getChecked(){return mCheckBox.isChecked();}
}
3 自定義組合控件的屬性
-- 3.1 創建自定義屬性/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中調用自定義的組合控件
<?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="設置中心"/><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="自動升級"app:setting_des_on="自動升級開啟"app:setting_des_off="自動升級關閉" /><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="軟件鎖"app:setting_des_on="軟件鎖開啟"app:setting_des_off="軟件鎖關閉" /></LinearLayout>
4 對控件的調用
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);//設置自動升級自定義點擊監聽事件 每一次點擊切換復選狀態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);}}});//對軟件鎖的點擊事件mSoftLockSv.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {if (mSoftLockSv.getChecked()){mSoftLockSv.setChecked(false);}else {mSoftLockSv.setChecked(true);}}});}
}
