I want to open an AlertDialog on the click of either a Button or TextView but I am not sure what would work best. When a selection is made in the AlertDialog, I want the bottom text to be updated with the selection. Here are the two options I have:

TextViews only. Here, the LinearLayout will have listener and will open AlertDialog.

<LinearLayout

    android:id="@+id/container"

    android:layout_width="match_parent"

    android:layout_height="wrap_content"

    android:layout_marginTop="8dp"

    android:orientation="vertical">



    <TextView

        android:id="@+id/label"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:text="Label" />



    <TextView

        android:id="@+id/selection"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_marginLeft="5dp"

        android:layout_marginStart="5dp"

        android:textSize="18sp"

        android:text="Select..." />



</LinearLayout>

TextView and Button. Here, the Button will open the AlertDialog and the text inside the Button will be replaced with the selection.

<TextView

    android:id="@+id/label"

    android:layout_width="match_parent"

    android:layout_height="wrap_content"

    android:layout_marginTop="10dp"

    android:layout_marginLeft="5dp"

    android:layout_marginStart="5dp"

    android:text="Label"

    android:textSize="16sp"

    android:textColor="@android:color/white" />



<Button

    android:layout_width="match_parent"

    android:layout_height="wrap_content"

    android:layout_below="@id/label"

    android:layout_marginTop="-20dp"

    android:text="Select..."

    android:textAllCaps="false"

    android:textColor="@android:color/white"

    android:gravity="start|center_vertical"

    android:paddingLeft="15dp"

    android:paddingStart="15dp"

    android:paddingRight="15dp"

    android:paddingEnd="15dp"

    android:paddingTop="15dp"

    android:textSize="18sp"

    android:background="@android:color/transparent" />

Answer is Button.

Button is a subclass of TextView. So it has all the features of TextView and additional features of Button class. Button adds a few stylistic changes (e.g., default background image, additional padding, ripple effect) to allow quicker adaptation to your designs.
