    If you are using a newer version of Android Studio (I am using 2.3.3) and are using the ConstraintLayout, you will need to set constraints. Otherwise, all of your widgets and text will just move to the default location in the top left corner (0,0).

    To automatically set constraints, just click on the component that you want to set, and click the "Infer Constraints" button. It should be right above the design workspace and looks like 2 yellow stars.

    Alt+enter after the line of code where the name of the widget is ( the text view), in order to extract the resource string.

    lightbulbs, strings and version 2.2+
    The fasted way I have found to find 'missing' strings is, just go in your .xml Text view, and press F2
    it will toggle to everything that is lacking a string. (WITH the clickable lightbulb in front of that line of text btw!)

    When ALL strings are set/fixed, F2 will jump to "typo's" (As in autocorrect.)
    So once you are only seeing those, it means all your strings are set/fixed.

    Can anyone tell me where I can find the Large Text widget in 2.2 version?

  12. Ulysses Avatar

    i'm using android studio 2.2 (yes I updated) and the button keeps moving every other way except the center. Anyone else having this problem? Also it seems as if I can't set the ID for anything for some reason the ID field in the properties stays blank even after I press enter.

    Hi Bucky,

    I was wondering is there a way to enter empty spaces within the grid so that there is more spacing between the wdigets.

    Thanks,

    I got a question. Every time I type "import android.widget.Button;" the whole line turns grey (like in your video) and then just disappears, any idea what could be causing this and how to fix this problem?
