效果图：
代码如下：
activity_main.xml
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
android:id="@+id/eatid"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="吃饭"
/>
android:id="@+id/sleepid"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="睡觉"
/>
android:id="@+id/dotaid"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="dota"
/>
有2种方法；
第一种是OnClickListener的使用方法：
代码如下:
MainActivity.java
package com.jk.test;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.CheckBox;
public class MainActivity extends Activity {
private CheckBox eatBox;
private CheckBox sleepBox;
private CheckBox dotaBox;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
eatBox=(CheckBox)findViewById(R.id.eatid);
sleepBox=(CheckBox)findViewById(R.id.sleepid);
dotaBox=(CheckBox)findViewById(R.id.dotaid);
onBoxClickListener listener =new onBoxClickListener();
eatBox.setOnClickListener(listener);
sleepBox.setOnClickListener(listener);
dotaBox.setOnClickListener(listener);
}
class onBoxClickListener implements OnClickListener{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
CheckBox box = (CheckBox)v;
if(box.getId()==R.id.eatid)
System.out.println("eatBox");
else if(box.getId()==R.id.sleepid)
System.out.println("sleepBox");
else if(box.getId()==R.id.dotaid)
System.out.println("dotaBox");
if(box.isChecked())
System.out.println("is checked!");
else
System.out.println("is unchecked!");
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}第二种是OnCheckedChangeListener的使用方法：
package com.jk.test;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
public class MainActivity extends Activity {
private CheckBox eatBox;
private CheckBox sleepBox;
private CheckBox dotaBox;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
eatBox=(CheckBox)findViewById(R.id.eatid);
sleepBox=(CheckBox)findViewById(R.id.sleepid);
dotaBox=(CheckBox)findViewById(R.id.dotaid);
CheckBoxListener listener =new CheckBoxListener();
eatBox.setOnCheckedChangeListener(listener);
sleepBox.setOnCheckedChangeListener(listener);
dotaBox.setOnCheckedChangeListener(listener);
}
class CheckBoxListener implements OnCheckedChangeListener{
public void onCheckedChanged(CompoundButton v, boolean isChecked) {
// TODO Auto-generated method stub
CompoundButton box = (CompoundButton)v;
if(box.getId()==R.id.eatid)
System.out.println("eatBox");
else if(box.getId()==R.id.sleepid)
System.out.println("sleepBox");
else if(box.getId()==R.id.dotaid)
System.out.println("dotaBox");
if(isChecked)
System.out.println("is checked!");
else
System.out.println("is unchecked!");
}
}
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
另外下面是实现全选的功能：
package com.jk.test;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
public class MainActivity extends Activity {
private CheckBox eatBox;
private CheckBox sleepBox;
private CheckBox dotaBox;
private CheckBox allClickBox;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
eatBox = (CheckBox) findViewById(R.id.eatid);
sleepBox = (CheckBox) findViewById(R.id.sleepid);
dotaBox = (CheckBox) findViewById(R.id.dotaid);
allClickBox = (CheckBox) findViewById(R.id.allClickid);
CheckBoxListener listener = new CheckBoxListener();
eatBox.setOnCheckedChangeListener(listener);
sleepBox.setOnCheckedChangeListener(listener);
dotaBox.setOnCheckedChangeListener(listener);
allClickBox.setOnCheckedChangeListener(listener);
}
class CheckBoxListener implements OnCheckedChangeListener {
public void onCheckedChanged(CompoundButton v, boolean isChecked) {
CompoundButton box = (CompoundButton) v;
if (box.getId() == R.id.eatid) {
if (isChecked)
System.out.println("eatBox is checked!");
else
System.out.println("eatBox is unchecked!");
}
else if (box.getId() == R.id.eatid) {
if (isChecked)
System.out.println("sleepBox is checked!");
else
System.out.println("sleepBox is unchecked!");
}
else if (box.getId() == R.id.eatid) {
if (isChecked)
System.out.println("dotaBox is checked!");
else
System.out.println("dotaBox is unchecked!");
}
else if (box.getId() == R.id.allClickid) {
if (isChecked) {
eatBox.setChecked(true);
sleepBox.setChecked(true);
dotaBox.setChecked(true);
}
else {
eatBox.setChecked(false);
sleepBox.setChecked(false);
dotaBox.setChecked(false);
}
}
}
}
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
