It is because you have yout item layout set to match_parent but TextViews to wrap_content. So by default it stays at the start position.

To fix this set your TextViews width to match_parent and gravity to center android:gravity="center"

So your item layout will look as below:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:weightSum="1">

<TextView
    android:id="@+id/tv_item_gridview"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="0.8"
    android:gravity="center"
    tools:text="2"
    android:textColor="#000" />

<TextView
    android:id="@+id/isDone"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="0.2"
    android:gravity="center"
    tools:text="13"
    android:visibility="visible" />
</LinearLayout>
