我从DB获取标题列表,并使用ArrayList
将这些标题添加到布局中。此布局是使用adapters
创建的。当我点击此布局中显示的标题时,我想打开另一个布局。我怎样才能解决这个问题?有任何建议请....

您要查找的是列表项单击侦听器。您可以尝试下面的lv.setOnItemCLickListener就是您的示例。
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getApplicationContext(),
"Click ListItem Number " + position, Toast.LENGTH_LONG)
.show();
}
});
遵循此基本example
没有像onClick到ArrayList那样,为视图设置了点击次数。

设置适配器后,必须设置“OnItemClickListener”:
getListView().setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// Your logic when clicking. You can get the object for that row by
// calling parent.get(position) and casting to your data type in your adapter.
// which in this case seems to be string.
}
});

在此示例中采用look解决方案,认为是这样:
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
//Here put the code for each item. You now the position in the array because is the same as item.
}

试试这个
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
Toast.makeText(getApplicationContext(), "Test", Toast.LENGTH_LONG).show();
}
