我想添加一個單選按鈕到我現有的列表視圖中，這樣一次只需要選擇一個單選按鈕。添加單選按鈕到列表視圖
ItemDetails：
public class ItemDetails {
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getItemDescription() {
return itemDescription;
}
public void setItemDescription(String itemDescription) {
this.itemDescription = itemDescription;
}
public String getPrice() {
return price;
}
public void setPrice(String price) {
this.price = price;
}
public int getImageNumber() {
return imageNumber;
}
public void setImageNumber(int imageNumber) {
this.imageNumber = imageNumber;
}
private String name ;
private String itemDescription;
private String price;
private int imageNumber;
}
適配器：
public class ItemListBaseAdapter extends BaseAdapter {
private static ArrayList<ItemDetails> itemDetailsrrayList;
private Integer[] imgid = {
R.drawable.img1,
R.drawable.img2,
R.drawable.img3,
R.drawable.img4,
R.drawable.img5,
R.drawable.img6
};
private LayoutInflater l_Inflater;
public ItemListBaseAdapter(Context context, ArrayList<ItemDetails> results) {
itemDetailsrrayList = results;
l_Inflater = LayoutInflater.from(context);
}
public int getCount() {
return itemDetailsrrayList.size();
}
public Object getItem(int position) {
return itemDetailsrrayList.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = l_Inflater.inflate(R.layout.item_details_view, null);
holder = new ViewHolder();
holder.txt_itemName = (TextView) convertView.findViewById(R.id.name);
holder.txt_itemDescription = (TextView) convertView.findViewById(R.id.itemDescription);
holder.txt_itemPrice = (TextView) convertView.findViewById(R.id.price);
holder.itemImage = (ImageView) convertView.findViewById(R.id.photo);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.txt_itemName.setText(itemDetailsrrayList.get(position).getName());
holder.txt_itemDescription.setText(itemDetailsrrayList.get(position).getItemDescription());
holder.txt_itemPrice.setText(itemDetailsrrayList.get(position).getPrice());
holder.itemImage.setImageResource(imgid[itemDetailsrrayList.get(position).getImageNumber() - 1]);
// imageLoader.DisplayImage("http://192.168.1.28:8082/ANDROID/images/BEVE.jpeg", holder.itemImage);
View row = convertView;
CheckedTextView checkBox = (CheckedTextView) row.findViewById(R.id.checkstate);
checkBox.setChecked(false);
return convertView;
}
static class ViewHolder {
TextView txt_itemName;
TextView txt_itemDescription;
TextView txt_itemPrice;
ImageView itemImage;
CheckedTextView checkBox;
}
}
ItemDetails.xml：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="@+id/photo"
android:layout_width="150dip"
android:layout_height="100dip"
android:paddingRight="15dp"
android:paddingLeft="15dp"/>
</LinearLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_marginLeft="160dp"
android:layout_marginTop="10dp">
<TextView android:id="@+id/name"
android:textSize="14sp"
android:textStyle="bold"
android:textColor="#000000"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView android:id="@+id/itemDescription"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/name"/>
<TextView android:id="@+id/price"
android:textSize="19sp"
android:textStyle="bold"
android:textColor="#003399"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/itemDescription"/>
</RelativeLayout>
</RelativeLayout>
的ListView：
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background ="#CCCCCC">
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:divider="#3366CC"
android:dividerHeight="2dp"
android:choiceMode="singleChoice"/>
</LinearLayout>
我見過很多SO anwsers但他們都不在了我的案子說加
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
誰能說我如何達致這？
