<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
