通知が届いている間にリスト項目の背景がハイライト表示されるリストビューがありますが、リストをスクロールすると項目が強調表示されるという問題があります。最初にスクロールしたときに最初のアイテムがリストされ、別のアイテムがハイライト表示されたとします。私はnotifysetdatachangedも使用しました。リストアクティビティのためのアンドロイドでスクロールしながらリストビュー項目が変わる
コード
public class NewPageActivity extends Fragment{
// notifcationは、Webサービスとセットアダプタ
を介してデータを取得するときのため@Override
public void onResume() {
super.onResume();
IntentFilter intentFilter = new IntentFilter(
"unique_name");
mMessageReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
//extract our message from intent
String msg_for_me = intent.getStringExtra("message");
//log our message value
Log.e("TAG", "onReceive: boradcast" + msg_for_me);
if (msg_for_me.contains("&")) {
String msg1[] = msg_for_me.split("&");
if (msg1[0].contains("Waiting for acceptance...")) {
edit.putInt("newTabHighlight", sp.getInt("newTabHighlight", 0) + 1);
edit.putString("newOrder", sp.getString("newOrder", null) + "&" + msg1[1].split("=")[1]);
edit.putInt("reminderTab", sp.getInt("reminderTab", 0) + 1);
