how to fix rendering problems on android studio

this is what it looks like

Rendering Problems Missing styles. Is the correct theme chosen for this layout? Use the Theme combo box above the layout to choose a different layout, or fix the theme style references. NOTE: One or more layouts are missing the layout_width or layout_height attributes. These are required in most layouts.

Solution

As explicitly stated in your error log, you have to set layout_width and layout_height attributes to all layouts in all your xml files.

In other words, your layout file should contain something like this inside its tags.

android:layout_width="wrap_content"
android:layout_height="wrap_content"

You should set it to wrap_content or match_parent according to the way it want to be,
