由 ▼魔方 西西 提交于 2020-01-02 04:27:06
问题 What's the shortest xamly way to make a ToggleButton contents depend on its checked state? In WPF I'd probably go for a DataTrigger which doesn't exist in Silverlight. I tried the following, but it doesn't work, as soon as I include the triggers, the binding to the source is broken.

Update a CheckBox in ListView row that corresponds to a database row

由 懵懂的女人 提交于 2020-01-01 15:11:27
问题 I already set android:focusable="false" on my CheckBox in my custom layout. My back-end SQLite database depends on whether or not the CheckBox is checked or not. Each row in my ListView corresponds to a row in my database. So my question is, where should I put on OnClickListener for the CheckBox so I can update the item associated with that ListView row? I would need it to be placed where I have access to an id. Maybe onListItemClick ? UPDATE: Here my custom adapter: package com.mohit.geo2do

问题 I have a datatable with rows containing some input text fields that are required. Each row also has a check box called delete.
