如何在FragmentList中實現onItemClick方法？

Question

我需要在一個標簽片段中使用listView，因此我從以下示例中實現了代碼： http : //geekswithblogs.net/bosuch/archive/2011/01/31/android---create-a-custom-multi-line-listview-綁定到一個.aspx 。 當MainActivity中的某些操作完成時，將顯示該列表，但我不知道如何單擊它。 我試過像本示例中所示，但是它不起作用，我認為問題是因為我有片段，該示例在MainActivity中。 請幫忙！

public class FragmentLogbook extends ListFragment {

        //handler for passing data through thread
        private Handler handler;
        //progress dialog
        private ProgressDialog progressDialog;

        private int progressBarStatus;

        SingletonLogbookPack mSingletonLogbookPack = SingletonLogbookPack.getInstance();
        ArrayList<SearchResults> searchResults = GetSearchResults();

        MyCustomBaseAdapter mAdapter;

        // Create an empty adapter we will use to display the loaded data.
        //CustomArrayAdapter mAdapter = new CustomArrayAdapter(getActivity());


        @Override
        public void onActivityCreated(Bundle savedInstanceState) {
            super.onActivityCreated(savedInstanceState); 

            handler = new Handler(); 
            startDownloadingLogbooks();

        } 

        private void startDownloadingLogbooks() {   
            progressDialog = new ProgressDialog(getActivity());
            //progressDialog = ProgressDialog.show(getActivity(),"Loading Logbooks", "Please wait...");
            progressDialog.setCancelable(false);
            progressDialog.setMessage("Loading Logbooks ...");
            progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
            progressDialog.setProgress(0);
            progressDialog.setMax(100);
            progressDialog.show();

            //reset progress bar status
            progressBarStatus = 0;

            // start the time consuming task in a new thread
            Thread thread = new Thread() {
                public void run () {
                    boolean p = ((MainActivity)getActivity()).mGpsColibri.mBinary.getLogbook();
                    while ( ((MainActivity)getActivity()).logbookFinished != true ) {
                        progressBarStatus = (int) ((MainActivity)getActivity()).GetProgressValue();
                        progressDialog.setProgress(progressBarStatus);
                        //in this time Progress dialog will be on screen                    
                    }
                    //set logbookFinished variable from MainActivity to false
                    ((MainActivity)getActivity()).logbookFinished = false;
                    // this will handle the post task.
                    // it will run when the time consuming task get finished
                    handler.post(new Runnable() {
                        @Override
                        public void run() {                     
                            // Update your UI or
                            // do any Post job after the time consuming task
                            // remember to dismiss the progress dialog here.
                            updateUI();
                            progressDialog.dismiss(); 
                        }
                    });
                }
            };

Answer 1

設置listview適配器后嘗試此操作

getListView().setOnItemClickListener(new OnItemClickListener() {

    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
            long arg3) {
        // TODO Auto-generated method stub

    }
});

Answer 2

您可以在updateUI()內部為ListFragment行添加onItemClick偵聽器：

private void updateUI() {

 mAdapter = new MyCustomBaseAdapter(getActivity(), searchResults);
 setListAdapter(mAdapter);
 ListView listview = FragmentLogbook.this.getListView(); //<< initialize ListView

 // set onItemClick here
  listview.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> adapterview, View view, int pos,
            long id) {

        // do your work here...
    }
  });
}

Answer 3

@Override
public void onListItemClick(ListView l, View v, int position, long id) {        
    super.onListItemClick(l, v, position, id);
    /// do your code here
}

Answer 4

listview.setOnItemClickListener(new OnItemClickListener() {
  @Override
public void onItemClick(AdapterView<?> arg0,View arg1, int arg2, long arg3) {

String requiredvalue= ((TextView) arg1.findViewById(R.id.viewid)).getText().toString();
Log.i("requiredvalue", requiredvalue);

}

要么

@Override
public void onListItemClick(ListView l, View v, int position, long id) {
    // TODO Auto-generated method stub
    super.onListItemClick(l, v, position, id);

    searchResults.get(position);
    Log.i("requiredvalue", ""+searchResults.get(position));
}
