Listview get item text

问题:

I need to grab selected item TEXT (not id). What can I write under onListItemClick to do that? I get:

java.lang.ClassCastException: org.eclipse.jdt.internal.debug.core.model.JDIObjectValue cannot be cast to org.eclipse.jdt.debug.core.IJavaArray

回答1:

One of the things passed to onItemClick is the view that was clicked:

abstract void onItemClick(AdapterView parent, View view, int position, long id)

Cast view to the appropriate type and call getText() on it; for example:

final String text = ((TextView)view).getText();

There are multiple ways to achieve this and it also depends on whether you are getting text from simple listView or from Custom ListView(with custom_list_item.xml).

For Simple ListView

lv.setOnItemClickListener(new OnItemClickListener() {

    public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {
        String text = lv.get(position).tostring().trim();//first method 
        final String text = ((TextView)view).getText();// second method
}});

For Custom ListView

lv.setOnItemClickListener(new OnItemClickListener() {

    public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {
        TextView textView = (TextView) view.findViewById(R.id.list_content);
//where list_content is the id of TextView in listview_item.xml

}});
