<LinearLayout xmlns:android= "http://schemas.android.com/apk/res/android"
android:layout_width= "fill_parent"
android:layout_height= "fill_parent"
android:orientation= "vertical"
>
<TextView
android:id= "@+id/encodioninfo"
android:layout_width= "wrap_content"
android:layout_height= "wrap_content"
android:text= "选中编码"
/>
<RadioGroup android:layout_width= "wrap_content"
android:layout_height= "wrap_content"
android:orientation= "vertical"
android:checkedButton= "@+id/utf8"
android:id= "@+id/encoding" >
<RadioButton
android:id= "@+id/utf8"
android:layout_height= "wrap_content"
android:layout_width= "wrap_content"
android:text= "UTF-8" />
<RadioButton
android:id= "@+id/gbk"
android:layout_height= "wrap_content"
android:layout_width= "wrap_content"
android:text= "gbk" />
<RadioButton
android:id= "@+id/gbk2318"
android:layout_height= "wrap_content"
android:layout_width= "wrap_content"
android:text= "gbk2318" />
</RadioGroup>
<TextView
android:id= "@+id/sexinfo"
android:layout_width= "wrap_content"
android:layout_height= "wrap_content"
android:text= "选择性别"
/>
<RadioGroup android:layout_width= "wrap_content"
android:layout_height= "wrap_content"
android:orientation= "horizontal"
android:checkedButton= "@+id/man"
android:id= "@+id/sex" >
<RadioButton
android:id= "@+id/man"
android:layout_height= "wrap_content"
android:layout_width= "wrap_content"
android:text= "男" />
<RadioButton
android:id= "@+id/woman"
android:layout_height= "wrap_content"
android:layout_width= "wrap_content"
android:text= "女" />
</RadioGroup>
</LinearLayout> |
再新建一个RadioGroupActivity,并在这个activity里面设置radio的选中点击事件,并将选中点击事件的内容显示出来
public class RadioGroupActivity extends Activity { private RadioGroup radiogroup; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.radiogroup); radiogroup =(RadioGroup)this.findViewById(R.id.encoding); radiogroup.setOnCheckedChangeListener(new OnCheckedChangeListener() { @Override public void onCheckedChanged(RadioGroup group, int checkedId) { // TODO Auto-generated method stub //获取选中的radiobutton内容 group.getCheckedRadioButtonId() RadioButton radiobutton = (RadioButton)RadioGroupActivity.this.findViewById(group.getCheckedRadioButtonId()); Toast.makeText(getApplicationContext(),"选中的内容是"+ radiobutton.getText().toString(),Toast.LENGTH_LONG).show(); } }); } }
效果
