Android Studio Layout Editor ConstraintLayout: pack vs chain

阅读更多关于 Android Studio Layout Editor ConstraintLayout: pack vs chain

问题 In the Android Studio Layout Editor I see the words "pack" and "chain" with respect to a ConstraintLayout . I know they both have something to do with multiple views being connected to each other in a line, but their difference is not clear to me. What is the difference between "pack" and "chain"? 回答1: Short answer A Chain is a group of views that are bound together in a vertical or horizontal line. Pack means that the views should be kept very closely together, ie, touch each other

问题 This is strange, yet I see it all the time as I have lots of reasons to display just a simple question mark in this app. When editing with the Eclipse graphical layout editor, everything is fine...until I tell a TextEdit or a Button to display just a question mark. Here's my code: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" >

阅读更多关于 Layout editor: How to show layout in framelayout container?

问题 I have a layout defined in XML as root ConstraintLayout that contains 4 empty frameLayouts for dynamically inflating fragments. In order to have a better design experience in the layout editor (Android Studio), is there a way to show/mimic the intended layouts in each of these framelayouts?

问题 I'd like to view my layouts in full screen in the layout editor. I'm using the eclipse plugin. I've already hidden the ActionBar by selecting a *NoActionBar theme in the combo, but the navigation bar is a different story. AFAIK it can only be hidden using flags in code. I need to make continuous tweaks in the activity xml files, and testing it in the emulator is a real pain, when not directly impossible (my PC can't run a full HD emulator, and I'd need to SSH another machine). Needless to say

问题 When I edit XML files in Eclipse using Android Common XML Editor I am only able to use the graphical layout editor. I see in pictures online how there are supposed to be tabs at the bottom for Graphical and Source but I have none. How do I get this fixed? Using Eclipse 4.2.1. Thanks! 回答1: That is probably a problem of Unity not displaying the editor correctly. I bet that you can still switch between the tabs using the keyboard.
