Menu
I'm stuck on a problem and I don't know, what causes it. I have a very simple Layout like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/my_text_view"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="NOTE_THIS"
android:textColor="#FFFFFF"
android:textSize="22dp"
android:text="TestText"/>
</LinearLayout>
which is included inside another layout. If I change the gravity inside the xml I see same Result in Layout-Editor and on my phone. If I wanna apply the Gravity programatically like with myTextView.setGravity(Gravity.CENTER) it doesn't Change anything. And I cannot set LayoutGravity in Java on a TextView
I'll tried for debug purposes to include them three times each with another gravity which does work even. So I assume everything is alright with my Layout and there has to be a Bug or something else I miss. Can someone give me a hint what I also can try, or what causes this problem?

In this code example of MainActivity. java file, first of all, we access the TextView from the xml file by the line "TextView txtView = findViewById(R. id. text_view);" and in the next line we set the text by the line "txtView.
getText(). toString(); int A = Integer. parseInt(a);
To center align text in TextView in Kotlin Android, set android:textAlignment attribute with the value “center” in layout file, or programmatically set the textAlignment property of the TextView object with View. TEXT_ALIGNMENT_CENTER in activity file.
If in linearlayout your orientation vertical, you can put the textview in the "horizontal center" by android:layout_gravity="center" . For centering textview vertically you need to set layout_height of textview to match_parent and set android:gravity to "center".
Set your TextView's width as android:layout_width="fill_parent" then you can set it programmatically using myTextView.setGravity(Gravity.CENTER)
