android - Transparent Image in Textview DrawableTop Not Showing Properly -


the images shown below in png format, transparent background.

i used textview per item consists of drawabletop image , text. wanted image transparent not working properly. tried alpha method transparency entire textview lighten. wanted image, not entire textview.

by way, used textview instead of linearlayout per item consisting of imageview , textview because ide prompted me warning , advised not have warning in code.

i have following code in android:

<textview         android:id="@+id/marketbtn"         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_gravity="bottom"         android:layout_weight="1"         android:background="@drawable/unselected_button"         android:drawabletop="@drawable/market_icon_0"         android:gravity="center"         android:paddingbottom="5dp"         android:paddingleft="1dp"         android:paddingright="1dp"         android:paddingtop="5dp"         android:text="@string/task_bar_lbl_market"         android:textappearance="?android:attr/textappearancesmall"         android:textcolor="#ffffff"         android:textsize="13sp" />

i confused next. should there help, grateful! more info, here's screen cap of bug:

<button         android:id="@+id/marketbtn"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_above="@+id/show"         android:layout_alignleft="@+id/name"         android:layout_marginbottom="36dp"         android:background="@drawable/unselected_button"         android:drawabletop="@drawable/market_icon_0"         android:text="@string/task_bar_lbl_market"         android:textcolor="#ffffff"         android:textstyle="bold" />
