【问题描述】：
我已经阅读了一些 SO 问题，例如 this 和 this，但仍然无法弄清楚我的代码有什么问题。
我有一个ListFragment，每一行都有一个TextView 和一个CheckBox。
单击CheckBox 可以正常工作，但单击TextView 没有任何作用，并且OnListItemClick 不会被调用。我还尝试动态添加一个OnClickListener，使其工作，但这不是正确的方法，而且它也缺乏点击的GUI反馈（项目被“突出显示”一秒钟）。
这是我用于每个项目的 textview_with_checkbox.XML：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
android:gravity="left"
android:descendantFocusability="blocksDescendants"
android:orientation="horizontal" >
<TextView
android:id="@+id/textview_event_name"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingLeft="3dp"
android:paddingTop="5dp"
android:focusable="true"
android:singleLine="false" />
<CheckBox
android:id="@+id/checkbox_for_event_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.05"
android:focusable="false"
android:clickable="false" />
</LinearLayout>
现在是代码：
@Override
public void onActivityCreated(Bundle savedInstanceState)
{
super.onActivityCreated(savedInstanceState);
displayEventsLogFiles();
}
@Override
public void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
String chosenItem = (String) getListAdapter().getItem(position);
mCallBack.onEventItemSelected(chosenItem);
}
static class myCustomAdapterViewHolder
{
public TextView eventName;
public CheckBox eventCheckBox;
}
private class myCustomAdapter extends ArrayAdapter<String>
{
private ArrayList<String> sortedList;
private Context m_oContext;
List<String> m_oValues = null;
public myCustomAdapter(Context cont, int viewResId, List<String> objects)
{
super(cont, viewResId, objects);
m_oContext = cont;
m_oValues = objects;
sortedList = new ArrayList<String>();
for (String str : objects)
sortedList.add(str);
java.util.Collections.sort(sortedList);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View l_oRowView = convertView;
myCustomAdapterViewHolder l_oInitializedViewHolder = null;
final int l_nPosition = position;
// Use convertView if possible, otherwise inflate a view:
if (l_oRowView == null)
{
LayoutInflater inflater = (LayoutInflater) m_oContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
l_oRowView = inflater.inflate(R.layout.textview_with_checkbox, parent, false);
// PlaceHolder pattern:
final myCustomAdapterViewHolder l_oViewHolder = new myCustomAdapterViewHolder();
l_oViewHolder.eventName = (TextView) l_oRowView.findViewById(R.id.textview_event_name);
l_oViewHolder.eventCheckBox = (CheckBox) l_oRowView.findViewById(R.id.checkbox_for_event_name);
l_oViewHolder.eventCheckBox.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
CheckBox cb = (CheckBox)v;
//cb.setChecked(!cb.isChecked());
String l_sFilename = l_oViewHolder.eventName.getText().toString();
if (cb.isChecked())
{
if (!m_lstSelectedFilenames.contains(l_sFilename))
m_lstSelectedFilenames.add(l_sFilename);
}
else
{
if (m_lstSelectedFilenames.contains(l_sFilename))
m_lstSelectedFilenames.remove(l_sFilename);
}
}
});
l_oViewHolder.eventCheckBox.setFocusable(false);
//l_oViewHolder.eventCheckBox.setClickable(false);
// "Add" the viewHolder as a tag:
l_oRowView.setTag(l_oViewHolder);
l_oInitializedViewHolder = l_oViewHolder;
}
else
l_oInitializedViewHolder = (myCustomAdapterViewHolder) l_oRowView.getTag();
// By now, the rowView is initialized, just get the viewHolder and then get the views from it, to update:
//myCustomAdapterViewHolder l_oViewHolder = (myCustomAdapterViewHolder) l_oRowView.getTag();
/*l_oInitializedViewHolder.eventName.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mCallBack.onEventItemSelected((String)getListAdapter().getItem(l_nPosition));
}
});*/
l_oInitializedViewHolder.eventName.setText(m_oValues.get(position));
return l_oRowView;
//return super.getView();
}
public myCustomAdapter(Context cont, int viewResId, String[] strings)
{
this(cont, viewResId, Arrays.asList(strings));
}
@Override
public String getItem(int position)
{
return sortedList.get(position);
}
@Override
public int getPosition(String item)
{
return sortedList.indexOf(item);
}
}
我在这里做错了什么？
我想要的只是能够选择“文件”进行删除，使用CheckBoxes

据我所知，ListView 中的 CheckBox 不能正常工作，所以我有一个更好的 MultichoiceItem 解决方案。如果你愿意，我可以发布这个..
