1.布局文件

<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:orientation="vertical"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" ><RadioGroupandroid:id="@+id/radioGroup1"android:layout_width="wrap_content"android:orientation="horizontal"android:layout_height="wrap_content" ><RadioButtonandroid:id="@+id/radio0"android:layout_width="wrap_content"android:layout_height="wrap_content"android:checked="true"android:text="男" /><RadioButtonandroid:id="@+id/radio1"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="女" /></RadioGroup></LinearLayout>

2.綁定事件(實(shí)現(xiàn)接口，注意導(dǎo)包)

package com.example.test2;import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.widget.Button; import android.widget.CheckBox; import android.widget.CompoundButton; import android.widget.RadioGroup; import android.widget.RadioGroup.OnCheckedChangeListener;public class MainActivity extends Activity implements OnCheckedChangeListener {private Button login_button;private Button reset;private RadioGroup rg;private Button other;private CheckBox checkBox1;private Button myButton;/** @Override protected void onCreate(Bundle savedInstanceState) {* super.onCreate(savedInstanceState);* setContentView(R.layout.activity_radiobutton);* * login_button = (Button) this.findViewById(R.id.loginButton); checkBox1 =* (CheckBox) findViewById(R.id.checkBox1);* checkBox1.setOnCheckedChangeListener(new OnCheckedChangeListener() {* * @Override public void onCheckedChanged(CompoundButton arg0, boolean arg1)* { // arg1代表是否選中 Log.i("tag", arg1 + ""); if (arg1) { Log.i("tag",* checkBox1.getText().toString()); }* * } }); }*/// 單選框 @Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_radiobutton);rg = (RadioGroup) this.findViewById(R.id.radioGroup1);rg.setOnCheckedChangeListener(this);}@Overridepublic 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;}@Overridepublic void onCheckedChanged(RadioGroup arg0, int checkId) {// TODO Auto-generated method stubswitch(checkId){case R.id.radio0:Log.i("tag", "當(dāng)前選中男");break ;case R.id.radio1:Log.i("tag", "當(dāng)前選中女");break ;default:break ;}}}
