Importing the Library
Simply add the following dependency to your build.gradle
file to use the latest version:
dependencies {
repositories {
mavenCentral()
}
compile 'com.sothree.slidinguppanel:library:3.4.0'
}
Usage
- Include
com.sothree.slidinguppanel.SlidingUpPanelLayout
as the root element in your activity layout. - The layout must have
gravity
set to eithertop
orbottom
. - Make sure that it has two children. The first child is your main layout. The second child is your layout for the sliding up panel.
- The main layout should have the width and the height set to
match_parent
. - The sliding layout should have the width set to
match_parent
and the height set to eithermatch_parent
,wrap_content
or the max desireable height. If you would like to define the height as the percetange of the screen, set it tomatch_parent
and also define alayout_weight
attribute for the sliding view. - By default, the whole panel will act as a drag region and will intercept clicks and drag events. You can restrict the drag area to a specific view by using the
setDragView
method orumanoDragView
attribute.
For more information, please refer to the sample code.
<com.sothree.slidinguppanel.SlidingUpPanelLayout
xmlns:sothree="http://schemas.android.com/apk/res-auto"
android:id="@+id/sliding_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="bottom"
sothree:umanoPanelHeight="68dp"
sothree:umanoShadowHeight="4dp">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="Main Content"
android:textSize="16sp" />
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center|top"
android:text="The Awesome Sliding Up Panel"
android:textSize="16sp" />
</com.sothree.slidinguppanel.SlidingUpPanelLayout>
For smooth interaction with the ActionBar, make sure that windowActionBarOverlay
is set to true
in your styles:
<style name="AppTheme">
<item name="android:windowActionBarOverlay">true</item>
</style>
However, in this case you would likely want to add a top margin to your main layout of ?android:attr/actionBarSize
or ?attr/actionBarSize
to support older API versions.
Caveats, Additional Features and Customization
- If you are using a custom
umanoDragView
, the panel will pass through the click events to the main layout. Make your second layoutclickable
to prevent this. - You can change the panel height by using the
setPanelHeight
method orumanoPanelHeight
attribute. - If you would like to hide the shadow above the sliding panel, set
shadowHeight
attribute to 0. - Use
setEnabled(false)
to completely disable the sliding panel (including touch and programmatic sliding) - Use
setTouchEnabled(false)
to disables panel's touch responsiveness (drag and click), you can still control the panel programatically - Use
getPanelState
to get the current panel state - Use
setPanelState
to set the current panel state - You can add parallax to the main view by setting
umanoParallaxOffset
attribute (see demo for the example). - You can set a anchor point in the middle of the screen using
setAnchorPoint
to allow an intermediate expanded state for the panel (similar to Google Maps). - You can set a
PanelSlideListener
to monitor events about sliding panes. - You can also make the panel slide from the top by changing the
layout_gravity
attribute of the layout totop
. - You can provide a scroll interpolator for the panel movement by setting
umanoScrollInterpolator
attribute. For instance, if you want a bounce or overshoot effect for the panel. - By default, the panel pushes up the main content. You can make it overlay the main content by using
setOverlayed
method orumanoOverlay
attribute. This is useful if you would like to make the sliding layout semi-transparent. You can also setumanoClipPanel
to false to make the panel transparent in non-overlay mode. - By default, the main content is dimmed as the panel slides up. You can change the dim color by changing
umanoFadeColor
. Set it to"@android:color/transparent"
to remove dimming completely.
Scrollable Sliding Views
If you have a scrollable view inside of the sliding panel, make sure to set umanoScrollableView
attribute on the panel to supported nested scrolling. The panel supports ListView
, ScrollView
and RecyclerView
out of the box, but you can add support for any type of a scrollable view by setting a custom ScrollableViewHelper
. Here is an example for NestedScrollView
public class NestedScrollableViewHelper extends ScrollableViewHelper {
public int getScrollableViewScrollPosition(View scrollableView, boolean isSlidingUp) {
if (mScrollableView instanceof NestedScrollView) {
if(isSlidingUp){
return mScrollableView.getScrollY();
} else {
NestedScrollView nsv = ((NestedScrollView) mScrollableView);
View child = nsv.getChildAt(0);
return (child.getBottom() - (nsv.getHeight() + nsv.getScrollY()));
}
} else {
return 0;
}
}
}
Once you define your helper, you can set it using setScrollableViewHelper
on the sliding panel.
Implementation
This library was initially based on the opened-sourced SlidingPaneLayout component from the r13 of the Android Support Library. Thanks Android team!
