Android：OnItemCLickListener无法在listview中运行

Question

I'm relatively new to Android development but my project was all going fairly well until I hit this problem. I have researched this question but none of the solutions to other questions have fixed my problem.

I have a SportsAvtivity which implements AdapterView OnItemClickListener but nothing is happening when I click on a list item.

Any Help would be greatly appreciated.

SportsActivity.java:

public class SportsActivity  extends Activity implements           AdapterView.OnItemClickListener {


ListView mainListView;
JSONAdapter mJSONAdapter;



private static final String QUERY_URL = "http://myurl.myurl/jsonOutput.php";
ProgressDialog mDialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sports);

    // Access the ListView
    mainListView = (ListView) findViewById(R.id.list);

    // Set this activity to react to list items being pressed
    mainListView.setOnItemClickListener(this);

    // Create a JSONAdapter for the ListView
    mJSONAdapter = new JSONAdapter(this, getLayoutInflater());

    // Set the ListView to use the ArrayAdapter
    mainListView.setAdapter(mJSONAdapter);

    mDialog = new ProgressDialog(this);
    mDialog.setMessage("Searching for Clubs");
    mDialog.setCancelable(false);

    // Create a client to perform networking
    AsyncHttpClient client = new AsyncHttpClient();

    // Show ProgressDialog to inform user that a task in the background is  occurring
    mDialog.show();

            // Have the client get a JSONArray of data
    // and define how to respond
    client.get(QUERY_URL, new JsonHttpResponseHandler() {

                @Override
                public void onSuccess(JSONObject jsonObject) {

                    // Dismiss the ProgressDialog
                    mDialog.dismiss();

                    // update the data in your custom method.
                     mJSONAdapter.updateData(jsonObject.optJSONArray("vfss"));
                }

                @Override
                public void onFailure(int statusCode, Throwable throwable, JSONObject error) {

                    // Dismiss the ProgressDialog
                    mDialog.dismiss();

                    // Display a "Toast" message
                    // to announce the failure
                    Toast.makeText(getApplicationContext(), "Network error, please close app and try again", Toast.LENGTH_LONG).show();

                    // Log error message
                    // to help solve any problems
                    Log.e("omg android", statusCode + " " + throwable.getMessage());
                }
            }
    );

}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

    // Now that the user's chosen an item, grab the cover data
    //JSONObject jsonObject = (JSONObject) mJSONAdapter.getItem(position);
    //String clubImage = jsonObject.optString("Image_Path","");

    Toast.makeText(SportsActivity.this,"Clicked",Toast.LENGTH_SHORT).show();

    // create an Intent to take you over to a new DetailActivity
    Intent clubIntent = new Intent(this, ClubActivity.class);

    // pack away the data about the cover
    // into your Intent before you head out
    //clubIntent.putExtra("clubImage", clubImage);

    // start the next Activity using your prepared Intent
    startActivity(clubIntent);
}

Answer 1

Just remove below from your JSONAdapter and it will work just fine :)

@Override
public boolean isEnabled (int position) {
   return false;
}

if not atleast return true .

Have a look here for more info.

Answer 2

Though a very old question, but I am still posting an answer to it so that it may help some one. As are using a layout inside the list view, use ..

android:descendantFocusability="blocksDescendants" 

.. on the first parent layout inside the list. This works as magic the click will not be consumed by any element inside the list but will directly go to the list item.

Answer 3

Try this and let me know if it works. Remove the

implements AdapterView.OnItemClickListener 

And add:

mainListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Toast.makeText(SportsActivity.this,"Clicked",Toast.LENGTH_SHORT).show();
    }
});

Answer 4

In your row.xml add this attribute in TextView and ImageView

android:focusableInTouchMode="false" 

This may work.
