I have a table in Android Studio and when I click on a cell, it should turn green, or any other color, that is not important, but I don’t know how to implement that.
I only have the xml file now and I am unsure what to add exactly and where.
It’s the first time when I try to implement something like that and I don’t know where I should start from or what I need for that.
Here is the xml:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:gravity="center"
android:stretchColumns="0,1,2">
<TableRow
android:id="@+id/blank"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="1dp"
android:background="#FFFFFF">
<TableRow
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_margin="1dp"
android:layout_weight="1"
android:background="#000000">
</TableRow>
</TableRow>

Could someone help, please?
Many many thanks.

Maybe it is useful for you to insert an EditText tag in every row so you can turn its color as you want like
"editTextVar.setBackground('some-color-code')".
I hope the best try for you.
Use it:
Or it(System colors):
