editedit\u信息Toast编辑信息 listViewEdit.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> listView, View view,
int position, long id) {
// Get the cursor, positioned to the corresponding listview_item_row in the result set
Cursor cursor = (Cursor) listView.getItemAtPosition(position);
// Get the state's capital from this listview_item_row in the database.
String ID =
cursor.getString(cursor.getColumnIndexOrThrow("_id"));
EditInformation fragment2 = new EditInformation();
Bundle bundle = new Bundle();
bundle.putString("ID", ID);
fragment2.setArguments(bundle);
FragmentManager fragmentManager = getSupportFragmentManager();
