    This is a studio studio previewer error. The surest solution to this problem is not to use it. Use a real device and / or emulator.

    • So usually there is no such problem ... It was in this project that I clicked somewhere wrong, or missed something and then it happened - Aleksey Timoshchenko
    • @AlekseyTimoshchenko This is the norm, it will not affect the work of the program, if you are very angry, you can change the API version on the panel above from the screenshot - BORSHEVIK
    • @AlekseyTimoshchenko, in theory, how should the written markup look like you should represent in your head, but really look at the real device. The previewer will always be with glitches, because it is useful only for the simplest tasks and for beginners and in Google it will not be brought to mind, for it is not meaningful. Therefore, do not use it at all. - Yuriy SPb ♦
    • @BORSHEVIK And where is the change of the API version on the screenshot? Walked through all the icons and did not find ... - Aleksey Timoshchenko
    • @YuriySPb I imagine how the markup should look, but as a beginner it’s very convenient for me to use the previewer, as it immediately shows what and how, where to indent, and where I forgot to put in the middle. This is more convenient than reloading the project to the phone every time - Aleksey Timoshchenko
