我是 Android 开发的新手，但在我遇到这个问题之前，我的项目进展顺利。我研究了这个问题，但其他问题的解决方案都没有解决我的问题。
我有一个 SportsAvtivity 实现了 AdapterView OnItemClickListener 但是当我点击列表项时没有任何反应。
任何帮助将不胜感激。
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);
}
}

public TextView titleTextView;
}
public void updateData(JSONArray jsonArray) {
// update the adapter's dataset
mJsonArray = jsonArray;
notifyDataSetChanged();
}
}
最佳答案
只需从您的 JSONAdapter 中删除下面的内容，它就会正常工作:)
@Override
public boolean isEnabled (int position) {
return false;
}
如果不是至少返回 true 。
