我有一个listview：
<ListView
android:clickable="true"
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
里面的元素是这样的：
<?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="fill_parent"
android:orientation="horizontal" >
<TextView
android:id="@+id/textview_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.76"
android:text="Choose"
android:clickable="true" />
<EditText
android:id="@+id/edittext_share"
android:layout_width="50dp"
android:layout_height="wrap_content"
android:layout_weight="0.12"
android:ems="10"
android:hint="share"
android:inputType="number" >
<requestFocus />
</EditText>
<EditText
android:id="@+id/edittext_spent"
android:layout_width="50dp"
android:layout_height="wrap_content"
android:layout_weight="0.11"
android:ems="10"
android:hint="spent"
android:inputType="number" />
</LinearLayout>
我希望当我单击 时TextView，应该会发生一些事情。我已经设置了setOnItemClickListener通过getListView()但它不起作用。
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
Toast.makeText(this,"clicked id="+arg2, Toast.LENGTH_SHORT).show();
}
和
ListView lv = getListView();
lv.setOnItemClickListener(this);
我该怎么做才能使 textview clicable？
编辑：我的适配器代码：
private class PeopleListAdapter extends BaseAdapter {
private LayoutInflater mInflater;
public Cursor cursor;
public ArrayList<PersonInfo> peopleList;
public ArrayList<PersonInfo> unsavedPeopleList;
public PeopleListAdapter(Context context, Cursor cursor) {
// Cache the LayoutInflate to avoid asking for a new one each time.
mInflater = LayoutInflater.from(context);
this.cursor = cursor;
peopleList = new ArrayList<PersonInfo>(cursor.getCount());
}
public PeopleListAdapter(Context context, Cursor cursor,
ArrayList<PersonInfo> unsavedList) {
this(context, cursor);
this.unsavedPeopleList = unsavedList;
}
/**
* The number of items in the list is determined by the number of
* speeches in our array.
*
* @see android.widget.ListAdapter#getCount()
*/
public int getCount() {
return peopleList.size() + unsavedPeopleList.size();
}
/**
* Since the data comes from an array, just returning the index is
* sufficent to get at the data. If we were using a more complex data
* structure, we would return whatever object represents one row in the
* list.
*
* @see android.widget.ListAdapter#getItem(int)
*/
public Object getItem(int position) {
return position;
}
/**
* Use the array index as a unique id.

}
/**

*
* @see android.widget.ListAdapter#getView(int, android.view.View,
* android.view.ViewGroup)
*/
public View getView(int position, View convertView, ViewGroup parent) {
// A ViewHolder keeps references to children views to avoid
// unneccessary calls

} else {

pInfo = new PersonInfo();
cursor.moveToPosition(position);

Cursor c = NewEventActivity.this.getContentResolver()
.query(pInfo.lookupUri,
new String[] { Contacts._ID,
Contacts.DISPLAY_NAME }, null,
null, null);
pInfo.share = cursor.getInt(1);
pInfo.spent = cursor.getInt(2);
try {
if (c.moveToFirst()) {
pInfo.name = c.getString(1);
}
} finally {
cursor.close();
}
peopleList.set(position, pInfo);
}
return pInfo;
} else {
