如果我遇到了您的问题，那么您可以静态创建带有笑脸图像的布局，并在活动B中调用并在活动A中使用。

You can create a simple activity and for it's design, create a layout that is not full screen layout:

Then add this Activity in the manifest file and add this theme to it:

android:theme="@android:style/Theme.Translucent.NoTitleBar"

And then you can add a blur effect to the surrounding of this Activity by adding this in onCreate of this Activity :

getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND, WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
