…衆ロ難τιáo~ 提交于 2019-12-11 02:37:41
问题 I am sure there is an easy solution to this one but I figured I would check with all the folks here first. I am working on a database creation and management application for android where the user creates and manages data along the line of what PHPMyAdmin does for regular computers. I have the section where the user creates a database and can insert tables with the appropriate styled data into the system. The next priority is selecting which DB to enter and modify its contents. Is there a way

问题 I first retrieve information from the SQLite database into a cursor. The cursor contains a timestamp column in the format: yyyy-MM-dd HH:mm:ss.SSS , for example, 2010-08-27 21:25:30.575 Once retrieved, I set a SimpleCursorAdapter like so (code simplified): SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.row_layout, cursor, new String{KEY_TITLE, KEY_TIMESTAMP}, new int[]{ R.id.title, R.id.timestamp } ); setListAdapter(adapter); The code successfully displays the time and

Android: Custom ArrayAdapter(s) for different custom objects

风格不统一 提交于 2019-12-11 02:31:12
问题 I have a number of custom objects that are significantly different from each other. These objects are stored in different lists and are to be displayed in different ListViews. Because of the design of these ListViews, I need to create my own custom ArrayAdapter. The thing is, the ListView design is supposed to be the same for all ListViews regardless of the objects in the list. To accomplish this I created an ArrayAdapter for every type of object. E.g. for a custom object coA I made an

How to add an item to a ListView with each Button click

无人久伴 提交于 2019-12-11 02:19:27
问题 This is the code I'm working on, it should simply add an item in a ListView (w/ array) each time the Button is clicked.

时光怂恿深爱的人放手 提交于 2019-12-11 01:53:59
问题 Once the user chooses a product from my ListView, it then puts the selected text from that ListView into an EditText. The problem I am having is when the user selects a product from the list, and then presses back, it comes up with the list again instead of returning to the EditText activity.

notifyDataSetChanged() fails to update adapter onClick

独自空忆成欢 提交于 2019-12-11 01:00:08
问题 I'm following this tutorial on ExpandableListViews. I want my implementation to show a new value added after tapping a button. However, nothing I have tried works. In addition to playing around with notifyDataSetChanged(), I also tried notifyDataSetInvalidated() and instantiating a new adapter, which were suggested in similar posts. The new data that isn't showing up is under my onClick method. Any suggestions on a fix? public class ClassesFragment extends Fragment implements OnClickListener
