The implementation method of nine kinds of dialog box for Android development _android

In the development process, with the user interactive will inevitably use the dialog box to achieve a better user experience, so mastering several dialog box implementation method is very necessary. Make a brief introduction to Alertdialog before looking at specific examples. Alertdialog is the most feature-rich, Practice-wide dialog box that generates a variety of content dialogs. But in fact the Alertdialog generated dialog box can be divided into the following 4 areas: Icon area, title area, content area, button area.

Here is a summary of the implementation of nine kinds of dialog boxes, the need for friends to learn under the

In addition to Popupwindow to achieve a little trouble, the other shape is relatively simple, familiar with the 2 can be
