我想改變單擊列表項的文本和複選框響應，但我不能這樣做。由於我無法獲取點擊列表項。 該片段是查看尋呼機的一部分。setOnItemClickListener不工作在片段
這裏是我的代碼，
public class ParticipantsFragment extends Fragment {
private ParticipantAdapter mAdapter;
SwipeRefreshLayout refreshLayout;
private String mParticipantId, mEventId, mGender;
ParticipantsAsyncTask task;
public ParticipantsFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mEventId = getArguments().getString(Config.BUNDLE_KEY_EVENT_ID);
mParticipantId = getArguments().getString(Config.BUNDLE_KEY_PARTICIPANT_ID);
mGender = getArguments().getString(Config.BUNDLE_KEY_GENDER);
Log.v("fragh", mEventId + " " + mParticipantId);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.participant_list, container, false);
TextView textView = (TextView) rootView.findViewById(R.id.no_participant);
task = new ParticipantsAsyncTask();
task.execute();
ListView participantListView = (ListView) rootView.findViewById(R.id.participant_list);
refreshLayout = (SwipeRefreshLayout) rootView.findViewById(R.id.swipe_refresh_layout_participant_list);
participantListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.v("Clicked Participant",mAdapter.getItem(position).getParticipantName());
EditText notes = (EditText) rootView.findViewById(R.id.participant_list_item_notes);
String text = notes.getText().toString();
Log.v("Participant Text",text);
CheckBox checkBox = (CheckBox) rootView.findViewById(R.id.participant_list_item_checkbox);
String check;
if(checkBox.isChecked())
{
check = "1";
}
else
{

}
}
});

submit.setOnClickListener(new View.OnClickListener() {
@Override

});

participantListView.setAdapter(mAdapter);
participantListView.setEmptyView(textView);
refreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override

task.execute();

}

// Clear the adapter of previous participant data
mAdapter.clear();
// If there is a valid list of {@link Event}s, then add them to the adapter's
// data set. This will trigger the ListView to update.
if (data != null && !data.isEmpty()) {
mAdapter.addAll(data);
}
}
@Override

List<Participant> result;
if (!mGender.isEmpty()) {

謝謝先生。它的工作，但現在我無法改變複選框的響應和編輯文本。 –
嘗試爲edittext添加TextWatcher，併爲您的pozo中的複選框設置一個布爾變量，這可能會幫助您更改值 –
我正在讀取日誌。在那裏，我看到，當我點擊TextView時，Touch up dispatch的日誌是針對ListView的，但是當我點擊edittext或複選框時，Touch up dispatch是針對edittext或textview的。任何想法！！ –
