preview text in textview Android Studio

Question

I've been using the following when creating layouts using the preview tool in Android Studio.

<TextView
    android:id="@+id/my_text_view"
    android:text="87%" />

The drawback is, if there is a delay before the real value is available, the UI will show 87% for a split second.

What are my options to handle this nicely?

Answer 1

For preview-only purposes, use the tools namespace:

<TextView
    android:id="@+id/my_text_view"
    tools:text="87%" />

This way the text only shows in IDE but not in runtime environment.

Declare tools with xmlns:tools="http://schemas.android.com/tools" in your XML's root element.
