layout_gravity not working

Question

Why my TextView doesn't go right?

Update: Well, now I don't just need to set TextView to the right. Now it is very interesting why layout_gravity doesn't work as expected, namely - set the View to the position inside it parent container.

<?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="wrap_content"
              android:minHeight="?android:attr/listPreferredItemHeight"
              style="@style/activated_item"
              android:orientation="horizontal">

    <CheckBox
        android:id="@+id/star"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginLeft="8dp"
        style="?android:attr/starStyle"/>

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:layout_marginLeft="8dp"
        android:layout_gravity="right" //////// HERE I AM 
        android:textStyle="bold"
        android:textColor="@color/item_text_color"/>

</LinearLayout>

Answer 1

I have found 2 solutions to that:

1. Set android:orientation="vertical".
2. Use FrameLayout instead of LinearLayout as the parent for your text/checkbox widgets. It is not primary usage of FrameLayout but that advice is also noted in Android documentation:

   ... You can, however, add multiple children to a FrameLayout and control their position within the FrameLayout by assigning gravity to each child, using the android:layout_gravity attribute.

Answer 2

Try to use gravity instead of layout_gravity.

Answer 3

Because you set orientation to horizontal, which means you cannot manually change horizontal position of your child views.
