As stated in Constraint Layout guides: If a view has no constraints when you run your layout on a device, it is drawn at position [0,0] (the top-left corner). You must add at least one horizontal and one vertical constraint for the view. I guess you haven’t applied any constraints. Either manually apply constraints to … Read more
Title and version should be in the chain and app:layout_constraintWidth_default=”wrap” used: <?xml version=”1.0″ encoding=”utf-8″?> <android.support.constraint.ConstraintLayout xmlns:android=”http://schemas.android.com/apk/res/android” xmlns:app=”http://schemas.android.com/apk/res-auto” xmlns:tools=”http://schemas.android.com/tools” android:orientation=”horizontal” android:layout_width=”match_parent” android:layout_height=”wrap_content” tools:background=”#b3b2b2″> <!– information button –> <ImageView android:id=”@+id/LibraryWithVersionItem.info” android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:paddingTop=”@dimen/margin8″ android:paddingLeft=”@dimen/margin8″ android:paddingRight=”@dimen/margin8″ android:paddingBottom=”@dimen/margin8″ android:scaleType=”center” android:src=”https://stackoverflow.com/questions/44099951/@drawable/ic_info_outline_white_24dp” app:layout_constraintRight_toRightOf=”parent” app:layout_constraintTop_toTopOf=”parent”/> <!– –> <TextView android:id=”@+id/LibraryWithVersionItem.title” android:layout_width=”0dp” android:layout_height=”wrap_content” android:layout_marginTop=”8dp” android:ellipsize=”middle” android:textColor=”@color/mySecondaryDarkColor” android:textSize=”@dimen/fontSize18″ android:textStyle=”bold” app:layout_constraintLeft_toLeftOf=”parent” app:layout_constraintTop_toTopOf=”parent” app:layout_constraintWidth_default=”wrap” tools:text=”ExampleLibrary 01234567890123456789012345″ app:layout_constraintRight_toLeftOf=”@+id/LibraryWithVersionItem.versions” … Read more
Update: This was reported as fixed in ConstraintLayout version 2.0.0 beta 6. See bug fixes for ConstraintLayout 2.0.0 beta 6 . This looks like a bug to me. GONE works but INVISIBLE doesn’t and I think it should. It may be worth a bug report unless someone can post where my thinking is wrong. (I … Read more
Short answer The best move will be replacing <merge> block with a (nested) ConstraintLayout rather than using redundant layout structure. ConstraintLayout is great but it doesn’t work well with composition and separation of responsibilities of each piece That is wrong. ConstraintLayout does work well with reusing layouts. Any layout in which all child views are … Read more
I achieved the max width percentage using two attributes: app:layout_constraintWidth_max=”wrap” app:layout_constraintWidth_percent=”0.4″ Example: <TextView android:id=”@+id/textView2″ android:layout_width=”0dp” android:layout_height=”wrap_content” android:layout_marginStart=”8dp” android:layout_marginTop=”8dp” android:text=”Helo world” android:textAlignment=”viewStart” app:layout_constraintStart_toStartOf=”parent” app:layout_constraintTop_toTopOf=”parent” app:layout_constraintWidth_max=”wrap” app:layout_constraintWidth_percent=”0.4″ /> The text width will increase to 40% of parent and then wrap if the content exceeds that.
Well, I saw the answer above and it worked for me too. But, I gave it a shot, and succeded converting my current project to Relative Layout. Do as follows: At activity_main.xml tab, change it to text. At the top of it, you’ll find the following: <android.support.constraint.ConstraintLayout xmlns:android=”http://schemas.android.com/apk/res/android” Just change all before xmlns to RelativeLayout. … Read more
Yes, as I know you can handle visibility using linear layout but not Enable/Disable views I think, correct me if I am wrong. So now in ConstraintLayout also we can handle visibility of particular group of views using the Group <android.support.constraint.Group/> This is new feature introduced in ConstraintLayout which is currently in Beta version. How … Read more
EDIT: Now that we are publishing ConstraintLayout directly on maven, you can check the maven directory: https://dl.google.com/dl/android/maven2/com/android/support/constraint/group-index.xml Look in the SDK Manager in Android Studio. If you check the “Show Package Details” in the SDK Tools section, you should see all the available verions of ConstraintLayout (under Support Repository -> ConstraintLayout for Android)
The Group in ConstraintLayout is just a loose association of views AFAIK. It is not a ViewGroup, so you will not be able to use a single click listener like you did when the views were in a ViewGroup. As an alternative, you can get a list of ids that are members of your Group … Read more
ConstraintLayout Chains Android developers recently released a new version of ConstraintLayout (1.0.2 as of today). This version contains a new major feature – Chains, which allows us to group views in ConstraintLayout. Chains provide group-like behavior in a single axis (horizontally or vertically). A set of widgets are considered a chain if they a linked … Read more
