Textview width is not the fit the width of the parent

Question

I couldn't make equal width of Textview and linearlayout. Although I set width match_parent in Textview it doesn't fit with the parent width.

I saw these posts : Android textView width not increasing

<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>

Answer 1

I resolved my problem by wrapping the views in a LinearLayout and followed by a small View beneath.

It is not clear why this worked.

<?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"
    android:background="?android:attr/selectableItemBackground"
    android:gravity="right|center_vertical"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:gravity="right|center_vertical"
        android:orientation="horizontal">

        <ImageView
            android:id="@+id/thumbnail"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_marginRight="@dimen/activity_horizontal_margin"
            android:src="@drawable/thumb" />

        <TextView
            android:id="@+id/title"
            style="@style/textViewItemStyle"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="16dp" />

    </LinearLayout>

    <View
        android:layout_width="match_parent"
        android:layout_height="2px" />

</LinearLayout>
