java create textview in middle

To create a TextView in the middle of a layout in Android, you can use the LinearLayout or RelativeLayout container and set the layout_gravity attribute to center.

Here is an example of how to create a TextView in the middle of a LinearLayout using XML layout file:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello, World!" />

</LinearLayout>

This creates a LinearLayout with vertical orientation and gravity set to center, and a TextView with the text "Hello, World!" inside the LinearLayout. The TextView will be centered vertically and horizontally in the layout.

You can also create a TextView in the middle of a RelativeLayout using the layout_centerInParent attribute. For example:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="Hello, World!" />

</RelativeLayout>
