how to clear error this

you should use scrollview like this sample
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.LinearLayoutCompat
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView />
<TextView />
<TextView />
</androidx.appcompat.widget.LinearLayoutCompat>
</androidx.core.widget.NestedScrollView>
Not Like this
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.LinearLayoutCompat
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</androidx.appcompat.widget.LinearLayoutCompat>
<TextView />
<TextView />
<TextView />
</androidx.core.widget.NestedScrollView>

Running too many tasks on UI Thread

I have been getting the above error for quite some time. Upon a lot of prodding around, I've come to the conclusion that its my xml itself which is causing this issue. I have commented ALL of my code in my java file and tried to load JUST THE LAYOUT. Even then the warning keeps popping up. I am herein attaching my xml file, hoping someone can shed some light on this. I would like to know what are the "heavy duty" work being performed which is causing my app to "skip frames".

How to create a TableLayout in that manner that the text did not go off the screen

I parsed the site and now trying to put the data into TableLayout. But I cannot properly build the table. In portrait orientation the result is aceptable, in landscape something terrible. Instead of 8 columns on screen it only shows 3.
It's what I want to achive - Schedule Online
A part of my activity_main.xml for landscape orientation.
Could you give me an advice of what shall I do to get proper schedule grid?

Scaling issue in a RadioButton with text

Please have a look at the following code

Basically, this gives the following UI
Now the problem is, the RadioButtons with text in the first column of the table takes only 40% of the available width. But, I need them to take 75% of the available width, and the things in second column can get the rest.
How can I do this?

Try this..

In WVGA 5.1 Screen, this generates the following UI
As you can see, there is a massive gap between rows. I want to avoid this, so it will look good in all smartphones. How can I do this?

Make height & width of tableRow as fill_parent and height of every LinearLayout also as fill_parent
Use this data
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".HomeScreen" >
<TableLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="*"
android:layout_margin="10dp"

Table row's height could be match_parent and width could be 0dip.

Try setting android:layout_margin to abit less and let me know if it solves the problem.

It's because your using linear layout in vertical and applying weight of 3

In your TableLayout Set the height to wrap_content and your space will be removed.
android:layout_height="wrap_content"
Also to get the best result of the android:weight property set the each layout's width to 0dp wherever you have assigned a weight.
