Android ListView With 2 TextViews Per Item

由 折月煮酒 提交于 2019-12-07 15:57:21
问题 All the examples I have seen on the net contain only 1 TextView per item and they load data from an array. I don't understand how do I specify which data goes where. For example my item layout looks like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/receiver" android:layout_width="wrap

由 天涯浪子 提交于 2019-12-07 14:05:03
问题 The ListView implements methods for filtering the content. Can you elaborate on when it should be used? As I understand it, that kind of filtering is suitable for the array based adapter -- all data already is in memory. This way, the filter just helps to skip the data that should not be displayed. However, if the ListView is used with a cursor adapter (SQLite database) for displayig a lot of items, the data may not be in memory. On the other hand, the filter value can be embed in the SQL

I'm aware that the selected item could be stored in the ViewModel. Here is the
