Android Studio 首选项布局选项卡完全损坏

Question

I am trying to create a settings menu in Android Studio, but the design tab is completely broken. When I drag and drop items into the screen, nothing happens. The two existing components are from the Text tab, however, as I am not very experienced in Android, the design tab is my best friend.

I've tried restarting Android Studio, and nothing. Does anyone know how to fix this? Thanks.

XML code:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.preference.PreferenceScreen>
    <SwitchPreferenceCompat />
    <EditTextPreference />
</android.support.v7.preference.PreferenceScreen>

Answer 1

Using the Text tab (now the Code tab) is more useful for PreferenceScreen. I think if you add android:title="" to all your defined Preference children in the XML file, it will show up.
