android - 如何在 Android TV 应用程序中设置画中画 (PiP) 的位置？

Question

有没有办法将画中画 (PiP) 窗口放在右上角(或其他地方)而不是屏幕的右下角(默认情况下)？或以编程方式设置确切位置？

Answer 1

引用下面的提交，这个设置可以帮助“config_defaultPictureInPictureGravity”

你可以引用https://cs.android.com/android/platform/superproject/+/master:frameworks/base/core/java/android/view/Gravity.java;l=45找出你需要的值(value)

例如重力.TOP | Gravity.RIGHT 为 0x35

    Changing initial PIP bounds specifications.
    
    - Change from a absolute bounds to a size, gravity and inset to
      allow easier tweaking of initial pinned stack bounds.
    
    Test: android.server.cts.ActivityManagerPinnedStackTests
    Test: #testPinnedStackDefaultBounds
    Test: #testPinnedStackMovementBounds
