I have started to dive into the Constraints Layout that were announced on the IO this year. This looks very promising and makes your layouts very efficient. I have seen the codelab excersize provided by Google. However I have the following questions that I would like to resolve. How can ConstraintLayouts be used to design the layout for different screen sizes? Currently I design the layout and set the views' margins and paddings etc for a specific device/screen group. Save those values in the dimens.xml file. This is a REALLY painful method to design the layouts. Does the Android

I have a TextView to the right of an image. I am trying to place some long text next to the image but this text should automatically end by adding "..." at the end. However, this does not work. I use this layout: <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="8dp" android:layout_marginLeft="8dp" android:layout_marginRight="8dp" android:layout_marginTop="8dp"> <ImageView android:id="@+id

Android: Keep ratio for a full-width and undefined height ImageView in a ConstraintLayout?

余生颓废 提交于 2019-12-04 05:08:21
问题 In a ConstraintLayout , an ImageView is bound to its parent in such a way that: Its left side is bound to the screen's left side Its right side is bound to the screen's right side Its top side is bound to a widget's bottom side Its bottom side is bound to the screen's bottom side Thus my ImageView appears to be full-width, and its height is the distance between a widget and the bottom of the screen. <ImageView android:id="@+id/imageView16" android:layout_width="0dp" android:layout_height="0dp

How to half overlap images in android constraint layout

亡梦爱人 提交于 2019-12-04 04:47:17
Is there any way to place an images half is on top of another image using only constraint layout. I know it can be done using relative and frame layouts but in the case of constraint layout is there anyway? prefer ways which do not require any hardcoding of heights/widths the requirement will look like this you can set layout using only constraint layout like below : <?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

ConstraintLayout Flow helper example

问题 I have read in a blog entry that in ConstraintLayout 2.0.0, a way was introduced to create a flow of views. What I exactly want to achieve: I have several TextView s with a fixed size next to each other. Depending on screen size, some TextView s should be pushed into the next line. Example on big screen with six TextViews : [AAA] [BBB] [CCC] [DDD] [EEE] [FFF] Example on small screen with six TextViews : [AAA] [BBB] [CCC] [DDD] [EEE] [FFF] I already saw this Stackoverflow question proposing to

How do margins in chains work in ConstraintLayout 1.1.0 (beta)

柔情痞子 提交于 2019-12-04 01:54:29
I have had a couple of my layouts blow up since changing over to ConstraintLayout version 1.1.0-beta4. Before I make any changes, I want to get a better understanding of how margins work in ConstraintLayout chains. In the following, I compare a layout in ConstraintLayout version 1.0.2 to version 1.1.0-beta4, but I believe that the issue first arose in 1.1.0-beta2. My goal is to have some text views stretch across the screen with gaps between the 1st and 2nd text views and the 2nd and 3rd text views. The background should show in these margins. To do this, I create a horizontal chain and

How to put AdView in ConstraintLayout at bottom and below other stuff?

廉价感情. 提交于 2019-12-04 00:10:11
I'm trying to migrate from RelativeLayout to ConstraintLayout but I'm having problems adding the AdMob AdView to the bottom and the rest of the content above it. For example, using RelativeLayout was that simple. You only need to put android:layout_alignParentBottom="true" on the AdView and android:layout_above="@+id/adView" on the view which is containing the stuff. I'm trying to understand how to migrate this sample code and these two lines of code to the equivalent using a ConstraintLayout instead of a RelativeLayout. Please, can someone help me with this migration? <?xml version="1.0"
