Android：直接从SQLite数据库填充ListView-无需使用ArrayList

[英]Android: Populate ListView directly from SQLite Database - without using ArrayList

原文 2013-12-21 13:02:04 3 2 android/ sqlite

Is it possible to populate a ListView from a SQLite Database without saving the data to an Array or List first? 是否可以从SQLite数据库填充ListView而无需先将数据保存到Array或List？ I have about 20000 lines of data in my SQLite Database. 我的SQLite数据库中大约有20000行数据。

Thanks! 谢谢！

You can use CursorAdapter to achieve this. 您可以使用CursorAdapter来实现。 Here goes a tutorial: http://www.mysamplecode.com/2012/07/android-listview-cursoradapter-sqlite.html 这是一个教程： http : //www.mysamplecode.com/2012/07/android-listview-cursoradapter-sqlite.html

Yes. 是。 This is possible. 这个有可能。 Use a SimpleCursorAdapter to populate your ListView directly from a database. 使用SimpleCursorAdapter直接从数据库填充ListView 。 To avoid performing database operations on the UI thread ( startManagingCursor and stopManagingCursor ), it is recommended to use a CursorLoader - backed by a ContentProvider - in order to load data asynchronously. 为了避免在UI线程（ startManagingCursor和stopManagingCursor ）上执行数据库操作，建议使用由ContentProvider支持的CursorLoader以便异步加载数据。 Read more... http://developer.android.com/guide/components/loaders.html https://developer.android.com/training/load-data-background/setup-loader.html 了解更多... http://developer.android.com/guide/components/loaders.html https://developer.android.com/training/load-data-background/setup-loader.html
