的Android上setOnItemClickListener無法正常工作如何選擇的值獲得 顯示爲ShareWithArticle @ 211f2370機器人如何選擇setOnItemClickListener得到應有的價值選擇
To.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String selected = String.valueOf(adapter.getItem(position));
}
});
我的代碼
public class CustomerAdapter extends ArrayAdapter<ShareWithArticle> {
private final Context mContext;
private final List<ShareWithArticle> mDepartments;

this.mContext = context;
this.mLayoutResourceId = resource;
this.mDepartments = new ArrayList<>(departments);
this.mDepartments_All = new ArrayList<>(departments);
this.mDepartments_Suggestion = new ArrayList<>();
}
public int getCount() {
return mDepartments.size();
}
public ShareWithArticle getItem(int position) {
return mDepartments.get(position);
}
public long getItemId(int position) {
return position;
}

你的適配器由 「ShareWithArticle」 類的對象。而不是「String selected = String.valueOf（adapter.getItem（position））;」使用此--- --- ShareWithArticle shareObj =（ShareWithArticle）adapter.getItem（位置） –
不工作請其他建議 –
請修正問題 –
