ConstraintLayout 1.1.0 different from 1.0.2, is it a bug?

由 这一生的挚爱 提交于 2019-12-07 04:12:05
问题 If I use 1.0.2, the 3 images' width is average, and the height of them is computed by the radio which I set. If I use 1.1.0, the height of them is 0dp and I can't see nothing, unless I set android:layout_height="match_parent" in the root ConstraintLayout . Is it a bug? Here is my code: <android.support.constraint.ConstraintLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <ImageView android:id="@+id/iv0" android:layout_width="0dp" android:layout_height="0dp"

Add Constraint Layout Barriers Missing In Context Menu of Android Android Studio

由 ￣綄美尐妖づ 提交于 2019-12-07 03:19:28
问题 I am currently going through a ConstraintLayout tutorial and stuck in a specific step (https://codelabs.developers.google.com/codelabs/constraint-layout/#10). The source is here (https://github.com/googlecodelabs/constraint-layout). Per instructions below, it says to add a vertical barrier but I do not see the add option in the menu. Actually the entire menu options look different. Where is the "Add Vertical barrier" menu? Right click on ConstraintLayout in the blueprint or the Component Tree

How can I set an ImageView's position dynamically in Constraint Layout

由 时光毁灭记忆、已成空白 提交于 2019-12-06 11:02:03
问题 I have a dynamically created ImageView in one Constraint Layout. Once I run the app the ImageView is showing on left top corner because no position is defined for the ImageView. How can I set the position(let's say CENTER) of the ImageView dynamically. I have written below code ConstraintLayout layout = (ConstraintLayout) findViewById(R.id.constraintLayout); ImageView imageView = new ImageView(ChooseOptionsActivity.this); imageView.setImageResource(R.drawable.redlight); layout.addView

ConstraintLayout in Cardview adding white space

由 故事扮演 提交于 2019-12-06 08:09:26
问题 I am trying to create a CardView that has a ConstraintLayout to organize some TextView . Sometimes it'll display as intended, but sometimes, it'll add extra white space such as when a keyboard is closed and ruin the layout. I have a GIF below showing the CardView working and not working in the same span of time. A code snippet for the relevant CardView is below. I use wrap_content to try to keep the CardView at the size I want, but it still expands. <android.support.v7.widget.CardView android

Is Constraint Layout expensive compared to others?

由 青春壹個敷衍的年華 提交于 2019-12-06 04:14:44
When I realize ConstraintLayout has: better layout drag-drop better view relative set-up with better naming "top-toBottomOf" better layout construction with ratios and percentage-guidelines and much more cant state here or I just didn't know that I was always wanted to using it constantly because it is so comfortable. 　 Just like the title, I curious about did ConstraintLayout will give big performance impact when using it constantly? Statement your opinion and evidence will be appreciated. Editing are welcome if you have good edition/grammar, and down-voting please leave your conclusion below
