CheckBox 多选按钮的使用方法

创建布局文件*声明一组多选按钮，设置各个按钮id .*

<LinearLayout xmlns: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" android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:paddingBottom="@dimen/activity_vertical_margin"    tools:context=".MainActivity"    android:orientation="vertical"    >***创建一组多选按钮，设置各个按钮id   ,统一由allcheck（全选按钮控制）***    <CheckBox        android:id="@+id/eat"        android:text="吃饭"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        android:layout_marginBottom="5dp"      />    <CheckBox        android:id="@+id/sleep"        android:text="睡觉"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="0dp"        android:layout_marginBottom="5dp"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        />    <CheckBox        android:id="@+id/dota"        android:text="打dota"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginBottom="5dp"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        />**重点内容**    <CheckBox        android:id="@+id/allChenked"        android:text="全选/全不选"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        /></LinearLayout>

MainActivity 中使用findViewById 获取对象，再为CheckBox 绑定相应的监听器（OnCheckedListener 以及OnCheckedChangeListener（在按钮选中状态发生改变时被调用））

public class MainActivity extends ActionBarActivity {    private CheckBox eatBox;    private CheckBox sleepBox;    private CheckBox dotaBox;    private CheckBox allCheckedBox;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);**//此处通过findViewById 找到相应的CheckBox**------------------------------------        eatBox=(CheckBox)findViewById(R.id.eat);        sleepBox=(CheckBox)findViewById(R.id.sleep);        dotaBox=(CheckBox)findViewById(R.id.dota);        allCheckedBox=(CheckBox)findViewById(R.id.allChenked);//生成监听器对象，给AllCheckBoxListener 实现监听器接口        AllCheckBoxListener listener = new AllCheckBoxListener();        allCheckedBox.setOnCheckedChangeListener(listener);//定义AllCheckBoxListener 类，用来实现监听器接口。     class  AllCheckBoxListener implements CompoundButton.OnCheckedChangeListener{// CompoundButton.OnCheckedChangeListener 用来监听CheckBox 对象的状态变化         @Override        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {//该方法内实现当allCheckedBox 状态变化时，eatBox,sleepBox,dataBox    三个CheckBox状态随之变化            eatBox.setChecked(b);            sleepBox.setChecked(b);            dotaBox.setChecked(b);//或者更改为复杂的代码方式//          if (allCheckedBox=isChecked()){//      eatbox.setChecked(ture);//      sleepbox.setChecked(ture);//      dotabox.setChecked(ture);//      }else{//          eatbox.setChecked(false);//          sleepbox.setChecked(false);//          dotabox.setChecked(false);//      }//        }    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.menu_main, menu);        return true;    }    @Override    public boolean onOptionsItemSelected(MenuItem item) {        // Handle action bar item clicks here. The action bar will        // automatically handle clicks on the Home/Up button, so long        // as you specify a parent activity in AndroidManifest.xml.        int id = item.getItemId();        //noinspection SimplifiableIfStatement        if (id == R.id.action_settings) {            return true;        }        return super.onOptionsItemSelected(item);    }}
