我嘗試使用由名稱選擇的上下文菜單項刪除聯繫人的以下代碼。如何在android中使用上下文菜單刪除聯繫人
public static boolean deleteContact(Context ctx, String phone, String name) {
Uri contactUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phone));
Cursor cur = ctx.getContentResolver().query(contactUri, null, null, null, null);
try {
if (cur.moveToFirst()) {
do {
if (cur.getString(cur.getColumnIndex(PhoneLookup.DISPLAY_NAME)).equalsIgnoreCase(name)) {
String lookupKey = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, lookupKey);
ctx.getContentResolver().delete(uri, null, null);
return true;
}
} while (cur.moveToNext());
}
} catch (Exception e) {
System.out.println(e.getStackTrace());
}
return false;
}
但我不知道如何把這個代碼到我的上下文菜單項選擇
public boolean onContextItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case 0:
return true;
}
return super.onContextItemSelected(item);
}
你的問題是什麼?把它放在這種情況下 – breceivemail
例如MyActivity.deleteContact(...) – breceivemail
ContactManager.deleteContact(ctx,phone,name); – Fuji
