Update 1 : After many attempts it's seems a general Issue after update IDE to version 3.1.2, till now there's only one solution which @mtak suggested although it is similar to the top menu options in the preview
Remove the line
tools:showIn="navigation_view"
from activity_main_drawer.xml and rebuild. This solved the same problem for me. Don't know why!!!
Problem solved in AS 3.1.3(8 June 2018) and reappeared again (16 June 2018)!!!
New temporary workaround:
- Cut the line
tools:showIn="navigation_view"from the menu file. - Close the menu file.
- Reopen it and paste the line.
- Go to design and see the menu as it should be.
If you close the menu file and reopen it the problem comes back! Still no preview in Text.
You can try the following:
Run Build then try to see the preview again
Close the current layout,open another then reopen again
Because you extend AppCompatActivity, you need to make sure that in your styles.xml your AppTheme is a descendant of AppCompat
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
That worked for me while the accepted answer for not that helping.
I have found the solution. Remove these two tool lines and close/reopen:
xmlns:tools="http://schemas.android.com/tools"
tools:showIn="navigation_view"
rebuilduing the project worked for me
