Collections.sort(Autori);
ArrayList<String> AutoriLetteraSelezionata = new ArrayList<String>();
for (String temp:Autori)
{if (temp.charAt(0)=='A'){AutoriLetteraSelezionata.add(temp);}}

listView.setAdapter(adapter);
listView.setClickable(true);
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
CharSequence autore = "("+((TextView)view).getText()+")";

推荐答案
您应该定义所有的项目列表视图的子对象(TextView的,ImageView的等):
You should define on all of the child objects in the item listview (TextView, ImageView etc.):
android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false"
和根项目RelativeLayout的/ LinearLayout中,因此,定义:
And for the root item RelativeLayout / LinearLayout and so, define:
android:clickable="false"
android:descendantFocusability="blocksDescendants"
android:focusable="false"
android:focusableInTouchMode="false"
如果您不能定义这些,他们将抓的单击事件。 如果你有一个自定义的ListView适配器,只需选中你重写:
If you won't define those, they will "catch" the click event. And if you have a Custom listView adapter, just check that you override:
@Override
public boolean isEnabled(int position)
{
return true;
}
