Show a Fragment in FrameLayout without element in layout editor?


Show a Fragment in FrameLayout without <fragment> element in layout editor?



I know that tools:layout can be used to show a fragment in <fragment> elements in the Android Studio's layout editor.


tools:layout


<fragment>



However, I want to add a fragment in a FrameLayout at runtime (so that I can change the fragment).



Similar questions found in SO like Question 1 and Question 2, but the answers in the pages cannot solve the problem exactly.



What I want to do is:


<fragment>


<include>


tools:layout


<fragment>


View.isInEditMode

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select.

Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
