不廢話,先來佈局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/imageview"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
>
<RadioGroup
android:id="@+id/radiogroup"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:checkedButton="@+id/rb1" >
<RadioButton
android:id="@+id/rb1"
android:text="1\n號\n佳\n麗" />
<RadioButton
android:id="@+id/rb2"
android:text="2\n號\n佳\n麗" />
<RadioButton
android:id="@+id/rb3"
android:text="3\n號\n佳\n麗" />
<RadioButton
android:id="@+id/rb4"
android:text="4\n號\n佳\n麗" />
</RadioGroup>
</LinearLayout>
關於佈局文件我也不多說了,一看就能明白,下面我貼Activity代碼
public class ImgCheckActivity extends ActionBarActivity {
private ImageView imageview;
private RadioGroup radiogroup;
private RadioButton rb1,rb2,rb3,rb4;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.checkimg);
imageview=(ImageView)super.findViewById(R.id.imageview);
rb1=(RadioButton)super.findViewById(R.id.rb1);
rb2=(RadioButton)super.findViewById(R.id.rb2);
rb3=(RadioButton)super.findViewById(R.id.rb3);
rb4=(RadioButton)super.findViewById(R.id.rb4);
/*
* 以匿名內部類的方法添加監聽器
* setImageResource()爲添加圖片資源
* checkedId爲匹配單選按鈕做選擇
*
*/
radiogroup=(RadioGroup)super.findViewById(R.id.radiogroup);
radiogroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
public void onCheckedChanged(RadioGroup group, int checkedId) {
if(checkedId==rb1.getId()){
imageview.setImageResource(R.drawable.ww);
}
else if(checkedId==rb2.getId()){
imageview.setImageResource(R.drawable.wa);
}
else if(checkedId==rb3.getId()){
imageview.setImageResource(R.drawable.ws);
}
else if(checkedId==rb4.getId()){
imageview.setImageResource(R.drawable.wd);
}
}
});
}
}
代碼很簡單,大家勿噴。
