介绍:
可以在dialog的后面造成模糊效果,模糊的实现是基于FastBlur算法实现的。运行效果:
使用说明:
最简单的使用方式是继承BlurDialogFragment或者SupportBlurDialogFragment。

/** * Simple fragment with blurring effect behind. */ public class SampleDialogFragment extends BlurDialogFragment { @Override public void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); this .debug( true ); this .setBlurRadius(4); this .setDownScaleFactor(5.0f); ... } ... } |
如果是android.support.v4.app.DialogFragment 则继承 SupportBlurDialogFragment

如果你不想使用继承的方式可以直接使用BlurEngine自定义一个DialogFragment
