</com.h6ah4i.android.materialshadowninepatch.MaterialShadowContainerView>| Property name | Default | Description |
|---|---|---|
ms9_shadowTranslationZ |
0dp |
Compatibility version of android:translationZ |
ms9_shadowElevation |
0dp |
Compatibility version of android:elevation |
ms9_forceUseCompatShadow |
false |
Enforces to use compatibility shadow on Lollipop or later |
ms9_affectsDisplayedPosition |
true |
Specify whether the shadow position is affected by the target view's position (emulates Lollipop's behavior) |
app:ms9_useAmbientShadow |
true |
Specify whether to use ambient shadow |
app:ms9_useSpotShadow |
true |
Specify whether to use spot shadow |
ms9_spotShadowDrawablesList |
@array/ms9_spot_shadow_drawables |
Specify Spot shadow (Key shadow) 9-patch resources |
ms9_ambientShadowDrawablesList |
@array/ms9_ambient_shadow_drawables |
Specify Ambient shadow 9-patch resources |
| Style name | |
|---|---|
ms9_DefaultShadowStyle([ Z6 or Z9 orZ18 ]) |
Default style (uses spot & ambient shadow, position affects) |
ms9_DefaultShadowStyle([ Z6 or Z9 or Z18 ])CompatOnly |
Default style with ms9_forceUseCompatShadow="true" |
ms9_NoDisplayedPositionAffectShadowStyle([ Z6 or Z9 or Z18 ]) |
No displayed position affects style |
ms9_NoDisplayedPositionAffectShadowStyle([ Z6 or Z9 or Z18 ])CompatOnly |
No displayed position affects style with ms9_forceUseCompatShadow="true" |
ms9_CompositeShadowStyle([ Z6 or Z9 ]) |
Pre-composite shadow style (less overdraws) |
ms9_CompositeShadowStyle([ Z6 or Z9 ])CompatOnly |
Pre-composite shadow style with ms9_forceUseCompatShadow="true" |
NOTE: You can specify Z[6|9|18] suffix for style names. This limits the deepest limit of shadow nine patch resources and it makes resource shrinking (shrinkResources true) work more effectively!
