java - Android 6 上的布局问题。充气机问题？在 Android 5 及更早版本上运行良好

Question

试图找出这个布局出了什么问题。该应用程序是客户端的，并实现了许多已弃用/不再维护的库(actionbar sherlock、jess.ui.grid.lib、com.handmark.pultorefresh.library)。在 Android 5 (Nexus 7) 上一切正常，但在 Android 6 (Nexus 5) 上，布局中的图像消失，TextView 可见，但它们最终在屏幕上分散得很远。该 View 在 Eclipse 中看起来不错。如果我将 View 放入独立的应用程序中，它就可以正常工作。不幸的是这个应用程序有点复杂，而且我不是 Android 专家，所以很难调试。因此，我们非常感谢任何帮助。

我知道可能性不大，因为我无法真正提供重现此问题的示例项目，但我希望有人遇到类似的情况并可以提供帮助。

首先是图片:Nexus 7 - Android 5.1.1 好

Nexus 5 - Android 6.0 ...一些文本在屏幕下方可见，但没有图像，也不是所有文本。

我在 Android 6.0 中遇到了几乎相同的问题，同时在 Linearlayout 中有一些 subview 。我将 Linearlayout 更改为 android.support.v7.widget.LinearLayoutCompat，它在 Android 6.0 及其以下版本上运行良好。

希望这对您有帮助!
