是否可以使此代码更容易/更短？我们在25个以上的对象上使用代码。

Answer 1

是。您可以创建一个可以实现技巧的方法：

private void hide(View... widgets) {
   for (View v: widgets) {
      v.setVisibility(View.GONE);
   }
}

相当于显示小部件（如果您想要使用它）：

private void show(View... widgets) {
   for (View v: widgets) {
      v.setVisibility(View.VISIBLE);
   }
}

由于所有小部件都从View扩展而来，因此您可以使用上面没有恐惧的方法来处理任何小部件。

用法（针对您的情况）：

hide(exodusTekst, exodusImage, fotballpubenTekst, ovenpoTekst);

Answer 2

为所有图像创建setVisibility方法，然后使用该方法。

或使用任何布局中的所有视图，只是该布局将隐藏...

Answer 3

如果有太多视图需要更改，为什么不创建两个布局并通过调用setContentView()然后onResume()在它们之间切换，并将onCreate()长实现移动到{{1 }}
