我为我的片段之一准备了一个很长的onActivityCreated，因为它必须初始化一个很大的网格布局。我没有使用xml，而是通过编程方式进行了此操作，因为与使用xml创建108个单独的视图相比，编写代码更容易。唯一的问题：创建片段时，要永久加载所有内容。
我尝试使用AsyncTaskLoader，但没有用，因为您无法使用其他线程更改视图。无论如何，请告诉我，我可以使其运行更快或更佳。这是我的第一个应用程序，因此很有可能我真的很傻。任何帮助表示赞赏。
我还在此片段中做很多事情，例如使用媒体播放器和使用onclicklisteners。所有这些都可以完美地运行，但加载片段的速度确实很慢。这是我的代码：
@Override
public void onActivityCreated(Bundle savedInstanceState) {
if (savedInstanceState == null) {
TextViewCompat.setAutoSizeTextTypeWithDefaults(textTranslation, TextViewCompat.AUTO_SIZE_TEXT_TYPE_UNIFORM);

final MediaPlayer[] sound_resource = {MediaPlayer.create(v.getContext(), R.raw.a_sound),
MediaPlayer.create(v.getContext(), R.raw.b_sound), MediaPlayer.create(v.getContext(), R.raw.c_sound),

您可以尝试将Recycler View用作网格视图，并通过创建自定义Recycler View Adapter来使用。我认为它会快速工作，因为“回收站”视图仅创建在屏幕上可见的带有少量偏移的单元。
您可以在Recycler视图here的Grid视图上获得帮助。
