I have to delete images from recyclerview, so for that, I'm added one delete button at the top right corner of the cardview. But in some cards that delete button is positioned properly and in some cards it is not.
Here is my XML file code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/cardview"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="4dp">
<android.support.constraint.ConstraintLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imageview"
android:layout_width="wrap_content"
android:layout_height="150dp"
android:src="#drawable/android"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="4dp"
android:text="1"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="#+id/imageview"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toEndOf="#+id/imageview" />
<ImageButton
android:id="#+id/bt_delete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:srcCompat="#drawable/ic_delete" />
</android.support.constraint.ConstraintLayout>
</android.support.v7.widget.CardView>
Below is the output
Here delete button is not displayed properly in the top three cards but it is displayed properly at bottom cards
It is also displayed properly in portrait mode:
Please tell me what I have to do in order to solve this problem
The inner ConstraintLayout has
android:layout_width="wrap_content"
Should be
android:layout_width="match_parent"
See if this helps:

I have a problem with the focus. Everytime I click in the EditText I can write 1 character and then it loses the focus.
I´ve searched and I found some solutions if my EditText is inside a RecyclerView, but those don´t work with my project. I suspect that this is because my EditText is inside a RecyclerView which is inside a CustomDialog.
If someone know how to solve this it would be great :D
Edit:
This is the xml code of the CustomDialog that contains the RecyclerView:

And this is the xml code of the CardView, which is the View that receives the RecyclerView, that contains the EditText:
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent"

android:hint="0.00"
android:inputType="numberDecimal"
android:minHeight="48dp" />
</LinearLayout>
</androidx.cardview.widget.CardView>
</androidx.constraintlayout.widget.ConstraintLayout>
We put requestFocus() and requestFocusFromTouch() and it works:
#personGasto is the editText
override fun afterTextChanged(p0: Editable?) {
#...
#some code
#...
personGasto.requestFocus()
personGasto.requestFocusFromTouch()
}
I want to put the bottom navigation menu with my recyclerview at the bottom of the view. It is currently at the top and I need help sending it to the bottom.
This is how it look now:
This is my xml code:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"
android:layout_height="wrap_content"
app:menu="#menu/botton_nav_menu"

</androidx.constraintlayout.widget.ConstraintLayout>
Add
app:layout_constraintBottom_toBottomOf="parent"
To bottom navigation item so code will be like that
<com.google.android.material.bottomnavigation.BottomNavigationView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:menu="#menu/botton_nav_menu"
tools:ignore="MissingConstraints" />
I have made some changes and this is how it the items are positioned now.
This is how the code looks now. If this helps you, an upvote would be appreciated. Thanks

Most probably that is because you put more than 1 view inside ScrollView , ScrollView expects 1 view from you. If you want to put more than one consider using a viewGroup view and put your views inside it. For Instance , you can use a vertical LinearLayout to wrap the Views you used. Also , consider using NestedScrollView instead.
Try this one
<?xml version="1.0" encoding="utf-8"?>
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
android:id="#+id/swipe_refresh"

Why not try a nested scroll view.
I am using Fragment in my app. I try to put a Button top of layout but it does not go to top of the layout.
This is my xml of Fragment :

it looks like this :
I need to put that two button top of the layout
How I can solve this issue
Thanks
You probably have a padding or margin attribute in your activity's xml file. Find;
android:paddingTop="?attr/actionBarSize"
or
android:marginTop="?attr/actionBarSize"
and remove them.
I am using Android Studio 3.0 to make an Android App.
But the issue I am facing is that the Layout editor/previewer is not working properly. It is sometimes not showing anything and at times it is showing a grey box with all the navigation buttons.
These are the screenshots
I am using the buildToolsVersion '26.0.2' and the support libraries version is 23.0.1
Any help would be really helpful.
EDIT: This is my XML Layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="100dp"/>
<ImageView
android:id="#+id/logo"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_gravity="center"
android:background="#drawable/logo" />
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="10dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#FFFFFF"
android:textSize="33dp"
android:textStyle="bold" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dp"
android:layout_marginBottom="15dp">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="15dp"
android:textColor="#FFFFFF" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
You had a couple of problem with structuring your UI. Here is a fix, also make sure that the #drawable/logo file is at the drawable folder
<?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"

android:id="#+id/relativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
