I think you should use this :

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

And I think for calculator if you use horizontal linearlayout instead of gridlayout its better too.

in the other hands for per row use horizontal linearlayout.

TextView's width is match_parent change it to wrap_content it will work and show your GridLayout or chanage your orientation of LinearLayout to vertical
