Gradient background doesn't work in some Devices
android, android-layout, gradient
Solution
Remove this block (first item block) from your shadow_background.xml.
<item>
<shape android:shape="rectangle" >
</shape>
</item>
To check shadow_background, I made a layout like this and it seems to work (even on API10 in xml editor). (If you leave the first item block, LinearLayout will be filled with black color.)
FrameLayout
(Background = @color/light_green)
LinearLayout
(Background = @drawable/shadow_background)
Problem
I'm using a gradient drawable for a Image inner-shadow, It works fine for some devices(check in emulator) but doesn't work in some.First i thought it will depend on api level of device but today i check same thing on Tablet having api level "16" (i.e jelly bean) and it doesn't work on it either. Gradient code(For inner shadows for all four sides): ``` <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item> <shape android:shape="rectangle" > </shape> </item> <item android:bottom="114dip" android:top="0dip"> <shape android:shape="rectangle" > <gradient android:angle="270" android:endColor="#00000000" android:startColor="#40000000" /> </shape> </item> <item android:bottom="0dip" android:top="114dip"> <shape android:shape="rectangle" > <gradient android:angle="90" android:endColor="#00000000" android:startColor="#40000000" /> </shape> </item> <item android:left="0dip" android:right="114dip"> <shape android:shape="rectangle" > <gradient android:angle="360" android:endColor="#00000000" android:startColor="#40000000" /> </shape> </item> <item android:left="114dip" android:right="0dip"> <shape android:shape="rectangle" > <gradient android:angle="180" android:endColor="#00000000" android:startColor="#40000000" /> </shape> </item> </layer-list> ``` my layout code : ``` <FrameLayout android:id="@+id/about" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:layout_weight="1" android:background="@color/light_green" > <ImageView android:id="@+id/home_icon_placeholder" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/home_icon_placeholder" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:drawablePadding="5dp" android:drawableTop="@drawable/about_icon" android:gravity="center" android:text="@string/about_champions_club_btn_txt" android:textColor="@android:color/white" android:textSize="12sp" android:textStyle="bold" /> </FrameLayout> ``` and uisng gradient in my code as : ``` int sdk = android.os.Build.VERSION.SDK_INT; if (sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) { placeHolderImageViewAbout.setBackgroundColor(getResources().getColor(R.color.transparent)); } else { //shadow background is above mention gradient placeHolderImageViewAbout.setBackgroundResource(R.drawable.shadow_background); } ```
