In layout of the Activity I have:

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/button_arrow" <!-- I NEED IMPLEMENT THIS -->
        android:clickable="true"
        android:drawablePadding="7dp"
        android:gravity="center"
        android:drawableLeft="@drawable/music_cloud"
        android:onClick="exportSong"
        android:padding="20dp"
        android:text="@string/export_upload"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:textColor="@color/dark_yellow_text_color"
        android:textStyle="bold" />

I tried modify several XML definition but nothing was good. Is there some easy way how to implement this shape? Also it should have a transparent background.
