DrawerLayout getting stuck on swipe

Note that you can get around this 20dp peek feature by setting the clickable attribute to true on the FrameLayout within the DrawerLayout.

android:clickable=”true”

for instance :

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <!-- The main content view -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clickable="true" />
    <!-- The navigation drawer -->
    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#111"
        android:choiceMode="singleChoice"
        android:divider="@android:color/darker_gray"
        android:dividerHeight="1dp" />
</android.support.v4.widget.DrawerLayout>
