你这是单选按钮,不可能同时提交这么多选项的内容,只能提交一个选项数据. 单选按钮RadioButton应该放在RadioGroup里面,对RadioGroup进行监听才行.
布局:
<RadioGroup
android:id="@+id/radioGroup1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="38dp"
android:layout_marginTop="52dp" >

<RadioButton
android:id="@+id/radio0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="学习" />

<RadioButton
android:id="@+id/radio1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="游戏" />

<RadioButton
android:id="@+id/radio2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="吃饭" />
</RadioGroup>

MainActivity.java里面
public class MainActivity extends Activity {

private RadioGroup rg;
private MyOnCheckedChangeListener listener;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

rg = (RadioGroup) findViewById(R.id.radioGroup1);
listener = new MyOnCheckedChangeListener();
rg.setOnCheckedChangeListener(listener);

}

private class MyOnCheckedChangeListener implements OnCheckedChangeListener {

@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {

RadioButton rb = (RadioButton)findViewById(checkedId);
String text = rb.getText().toString();
switch (checkedId) {
case R.id.radio0:
Log.i("XiaoXiaoTu", text);
break;
case R.id.radio1:
Log.i("XiaoXiaoTu", text);
break;
case R.id.radio2:
Log.i("XiaoXiaoTu", text);
break;
}

}
}

}
点击每个单选按钮都会打印对应按钮的内容,你只是显示的话,就简单用Toast一下就行.
