onItemClickListener不触发自定义ArrayAdapter [英] onItemClickListener not firing on custom ArrayAdapter
问题描述
我有一个活动来自Web服务检索数据。这个数据是psented在$ P $一个的ListView 通过ArrayAdapter其膨胀一个 RelativeLayout的三 TextViews 里面，没有任何幻想，它做工精细。
I have an Activity that retrieves data from a web service. This data is presented in a ListView via an ArrayAdapter which inflates a RelativeLayout with three TextViews inside, nothing fancy and it work fine.
现在我想实现一个详细活动当用户点击在ListView一个项目，应该叫，听起来很容易，但我不能为我的生活获得onItemClickListener工作在我的ArrayAdapter。
Now I want to implement a Details Activity that should be called when a user clicks an item in the ListView, sounds easy but I can't for the life of me get the onItemClickListener to work on my ArrayAdapter.
这是我的主活动：
public class Schema extends Activity {
private ArrayList<Lesson> lessons = new ArrayList<Lesson>();
private static final String TAG = "Schema";
ListView lstLessons;
Integer lessonId;
// called when the activity is first created.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// can we use the custom titlebar?
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
// set the view
setContentView(R.layout.main);
// set the title
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.titlebar);
// listview called lstLessons
lstLessons = (ListView)findViewById(R.id.lstLessons);
// load the schema
new loadSchema().execute();
// set the click listeners
lstLessons.setOnItemClickListener(selectLesson);
}// onCreate
// declare an OnItemClickListener for the AdapterArray (this doesn't work)
private OnItemClickListener selectLesson = new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View v, int i, long l) {
Log.v(TAG, "onItemClick fired!");
}
};
private class loadSchema extends AsyncTask<Void, Void, Void> {
private ProgressDialog progressDialog;
// ui calling possible
protected void onPreExecute() {
progressDialog = ProgressDialog.show(Schema.this,"", "Please wait...", true);
}
// no ui from this one
@Override
protected Void doInBackground(Void... arg0) {
// get some JSON, this works fine
}
@Override
protected void onPostExecute(Void result) {
progressDialog.dismiss();
// apply to list adapter
lstLessons.setAdapter(new LessonListAdapter(Schema.this, R.layout.list_item, lessons));
}
我的ArrayAdapter code：
My ArrayAdapter code:
// custom ArrayAdapter for Lessons
private class LessonListAdapter extends ArrayAdapter<Lesson> {
private ArrayList<Lesson> lessons;
public LessonListAdapter(Context context, int textViewResourceId, ArrayList<Lesson> items) {
super(context, textViewResourceId, items);
this.lessons = items;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.list_item, null);
}
Lesson o = lessons.get(position);
TextView tt = (TextView) v.findViewById(R.id.titletext);
TextView bt = (TextView) v.findViewById(R.id.timestarttext);
TextView rt = (TextView) v.findViewById(R.id.roomtext);
v.setClickable(true);
v.setFocusable(true);
tt.setText(o.title);
bt.setText(o.fmt_time_start);
rt.setText(o.room);
return v;
}
}// LessonListAdapter

被搞乱这最后几个小时，我似乎无法让我的头周围的问题是什么。我的问题看起来非常相似，<一个href="http://stackoverflow.com/questions/5066220/get-specific-item-property-on-onlistitemclick-using-custom-arrayadapter">this问题，但我不延长ListActivity，所以我还是不知道我的onListClickItem（）应该去。
Been messing with this for the last couple of hours and I can't seem to get my head around what the problem is. My problem looks very similar to this question, but I'm not extending ListActivity, so I still don't know where my onListClickItem() should go.
更新：现在我已经困惑这个好几天，但还是无法找到问题。
UPDATE: Now I've puzzled with this for several days and still can't find the issue.
我应该重写活动，这次延长ListActivity而不是活动？因为它提供了onItemClick方法本身并可能是更容易覆盖
Should I rewrite the activity, this time extending ListActivity instead of Activity? Because it provides the onItemClick method itself and is probably easier to overwrite.
或者，我应该在我的ArrayAdapter直接在每个getView（）绑定一个监听器？我相信，我已阅读，这是不好的做法（我应该做的，因为我试过，但在我的岗位）。
Or, should I bind a listener directly in each getView() in my ArrayAdapter? I believe I have read this is bad practice (I should do as I tried and failed in my post).
推荐答案
中找到的错误 - 这似乎是的这个问题。添加机器人：可调焦=假到每个list_item.xml元素的解决了这个问题，并且的onclick现在触发与原来的code
Found the bug - it seems to be this issue. Adding android:focusable="false" to each of the list_item.xml elements solved the issue, and the onclick is now triggered with the original code.
