本文实例讲述了Android开发中CheckBox的简单用法。分享给大家供大家参考，具体如下：

CheckBox是一种在界面开发中比较常见的控件，Android中UI开发也有CheckBox，简单的说下它的使用，每个CheckBox都要设置监听，设置的监听为CompouButton.OnCheckedChangedListener()。

package com.zhuguangwei; import android.app.Activity; import android.os.Bundle; import android.widget.CheckBox; import android.widget.CompoundButton; import android.widget.TextView; public class ChkBoxActivity extends Activity { private TextView myTextView; private CheckBox myApple; private CheckBox myOrange; private CheckBox myBanana; private CheckBox myWaterMelon; private CheckBox myStrawBerry; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //通过ID找到TextView myTextView = (TextView) findViewById(R.id.myTextView); //通过ID找到这几个CheckBox myApple = (CheckBox) findViewById(R.id.Apple); myOrange = (CheckBox) findViewById(R.id.Orange); myBanana = (CheckBox) findViewById(R.id.banana); myWaterMelon = (CheckBox) findViewById(R.id.watermelon); myStrawBerry = (CheckBox) findViewById(R.id.strawberry); myApple.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { // TODO Auto-generated method stub if(isChecked){ myTextView.append(myApple.getText().toString()); } else{ if(myTextView.getText().toString().contains("苹果")){ myTextView.setText(myTextView.getText().toString().replace("苹果", "")); } } } }); myOrange.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { // TODO Auto-generated method stub if(isChecked){ myTextView.append(myOrange.getText().toString()); } else{ if(myTextView.getText().toString().contains("橘子")){ myTextView.setText(myTextView.getText().toString().replace("橘子", "")); } } } }); myBanana.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { // TODO Auto-generated method stub if(isChecked){ myTextView.append(myBanana.getText().toString()); } else{ if(myTextView.getText().toString().contains("香蕉")){ myTextView.setText(myTextView.getText().toString().replace("香蕉", "")); } } } }); myWaterMelon.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { // TODO Auto-generated method stub if(isChecked){ myTextView.append(myWaterMelon.getText().toString()); } else{ if(myTextView.getText().toString().contains("西瓜")){ myTextView.setText(myTextView.getText().toString().replace("西瓜", "")); } } } }); myStrawBerry.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { // TODO Auto-generated method stub if(isChecked){ myTextView.append(myStrawBerry.getText().toString()); } else{ if(myTextView.getText().toString().contains("草莓")){ myTextView.setText(myTextView.getText().toString().replace("草莓", "")); } } } }); } }

main.xml文件内容为：

<"1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:id="@+id/myTextView" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="请选择你一下你喜欢吃的水果：" /> <CheckBox android:id="@+id/Apple" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="苹果" /> <CheckBox android:id="@+id/Orange" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="橘子" /> <CheckBox android:id="@+id/banana" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="香蕉" /> <CheckBox android:id="@+id/watermelon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="西瓜" /> <CheckBox android:id="@+id/strawberry" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="草莓" /> </LinearLayout>

运行结果为:
