我有一個ListFragment，我想添加一個正常的點擊偵聽器和一個長的。ListFragment上的ClickListener和LongClickListener
我重寫ListFragment上的onListItemClick（）方法。在這裏，它沒有問題。
然後，我創建了一個適配器，我通過在getView（）方法setOnLongClickListener（）增加了一個OnLongClickListener：
public class QuestionsAdapter extends BaseAdapter {
private QuestionsBean questions = null;
private LayoutInflater inflater = null;
public QuestionsAdapter(LayoutInflater inflater) {
this.inflater = inflater;
}
@Override
public int getCount() {
return (questions != null && questions.getQuestionList() != null) ? questions.getQuestionList().size() : 0;
}
@Override
public Object getItem(int position) {
return (questions != null && questions.getQuestionList() != null) ? questions.getQuestionList().get(position) : null;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
QuestionBean question = ((QuestionsBean) questions).getQuestionList().get(position);
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.item_fragment_question, null);
holder.questionItem = (TextView) convertView.findViewById(R.id.itemFragmentQuestions);
holder.questionItem.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
System.out.println("test => it works");
;
return false;
}
});
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.questionItem.setText(question.getQuestion());
return convertView;
}
private class ViewHolder {
TextView questionItem;
}
public void setQuestions(QuestionsBean questions) {
List<QuestionBean> temp = new ArrayList<QuestionBean>();
if (questions != null && questions.getQuestionList() != null) {
for (QuestionBean question : questions.getQuestionList()) {
if (question.isActivated()) {
temp.add(question);
}
}
questions.setQuestionList(temp);
}
this.questions = questions;
notifyDataSetChanged();
}
}
現在，longClickListener作品，但不正常的點擊了（其實它就像一個時間出10或15或20（這取決於...）。
我不知道爲什麼，當我同時設置監聽器，該onListItemClick（）不工作。
任何想法？
感謝您的幫助。
編輯：我行XML
<TextView
android:id="@+id/itemFragmentQuestions"
style="@style/ItemFragmentQuestion"
android:layout_marginBottom="@dimen/itemFragmentQuestionsMarging"
android:background="@drawable/background_validated" >
</TextView>
</LinearLayout>
編輯：
我ListFragment類：
public class QuestionsFragment extends ListFragment {
public static final int VALIDATED = 1;
public static final int IN_PROGRESS = 1;
public static final int NON_OBSERVED = 1;
private QuestionsAdapter adapter;
private QuestionsBean questions;
public QuestionsFragment() {
}
public QuestionsFragment(QuestionsBean questions) {
this.questions = questions;
}
public int getShownIndex() {
return getArguments() != null ? getArguments().getInt("index", 0) : 0;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
this.adapter = new QuestionsAdapter(inflater);
registerForContextMenu(getListView());
View questionsView = (LinearLayout) inflater.inflate(R.layout.fragment_questions, null);
setListAdapter(adapter);
return questionsView;
}
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
if (l == this.getListView()) {
QuestionBean question = (QuestionBean) l.getItemAtPosition(position);
TextView textView = (TextView) v.findViewById(R.id.itemFragmentQuestions);
switch (question.getValue()) {
case QuestionBean.OK:
question.setValue(QuestionBean.NOK);
textView.setBackgroundResource(R.drawable.background_in_progress);
break;
case QuestionBean.NOK:
question.setValue(QuestionBean.NA);
textView.setBackgroundResource(R.drawable.background_non_observed);
break;
case QuestionBean.NA:
question.setValue(QuestionBean.OK);
textView.setBackgroundResource(R.drawable.background_validated);
break;
}
}
}
@Override
public void onResume() {
super.onResume();
refresh(this.questions);
}
public void refresh(QuestionsBean questions) {
this.questions = questions;
adapter.setQuestions(questions);
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.setHeaderTitle("Menu Title");
menu.add(0, v.getId(), 0, "Option 1");
menu.add(0, v.getId(), 0, "Option 2");
}
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
if (item.getTitle() == "Option 1") {
// Option 1 code here
} else if (item.getTitle() == "Option 2") {
// Option 2 code here
}
return super.onContextItemSelected(item);
}
}
@Barak正如你所看到的，我設置了適配器onCreateView（）當我把registerForContextMenu（getListView（））放在後面時，我得到一個錯誤。看來，getListView（）尚未設置。
您對視圖中使用AdapterView.OnItemLongClickListener而不是OnLongClickListener每行試過嗎？ – pouzzler 2012-04-01 19:31:25
還是一樣:( – Nico 2012-04-01 20:07:09
能否請您提供您行XML？ – pouzzler 2012-04-01 20:12:12
