Android：ListView中的OnItemClickListener无法工作

Question

我相对于Android开发还比较新，但是我的项目一直顺利进行，直到我遇到了这个问题。我已经调查了这个问题，但是其他问题的解决方案都没有解决我的问题。

我有一个实现了AdapterViewOnItemClickListener的 SportsActivity，但当我点击列表项时却没有任何反应。

非常感谢您的帮助。

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);
}

添加Toast.makeText(SportsActivity.this,"Clicked",Toast.LENGTH_SHORT).show(); 然后告诉我它是否弹出提示。 - Eugene H

嗨，尤金，感谢您的回复。我也没有看到任何提示。如果有帮助，我已经添加了logcat？ - dmca

刚刚发布了一个答案。 - Eugene H

它是否成功发送了消息？ - Eugene H

删除所有的clickable="false"、focusable="false"和descendantFocusability="blocksDescendants"。 - njzk2

Answer 1

只需从您的JSONAdapter中删除以下内容，它就可以正常工作 :)

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

如果没有至少返回true。更多信息请参见这里。

我无法感谢你的足够，这让我快疯了！！你的答案正是我的适配器出了问题，我现在必须学习一下这个主题。我已经用Toast使它工作了。 - dmca

问题大多数都很小，但找到它们真的很难...很高兴能帮忙！！ - Mithun

Answer 2

试一下这个，如果可以的话请告诉我。删除

。

implements AdapterView.OnItemClickListener 

并添加：

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();
    }
});

- Eugene H

嗨。我删除了implements...，并将现有的setOnItemClickListener编辑为以上内容，但仍然没有toast。同时仍在获取ViewPostImeInputStage ACTION_DOWN。 - dmca

Answer 3

在你的 row.xml 文件中，在 TextView 和 ImageView 中添加此属性。

android:focusableInTouchMode="false" 

这可能有效。
