#BottomSheet
[](https://travis-ci.org/Flipboard/bottomsheet) [](https://gitter.im/Flipboard/bottomsheet?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
BottomSheet is an Android component which presents a dismissible view from the bottom of the screen. BottomSheet can be a useful replacement for dialogs and menus but can hold any view so the use cases are endless. This repository includes the BottomSheet component itself but also includes a set of common view components presented in a bottom sheet. These are located in the commons module.
BottomSheet has been used in production at Flipboard for a while now so it is thoroughly tested. Here is a GIF of it in action inside of Flipboard!
##Installation
If all you want is the BottomSheet component and don't need things from commons you can skip that dependency.
```groovy
repositories {
jcenter()
}
dependencies {
compile 'com.flipboard:bottomsheet-core:%%version%%'
compile 'com.flipboard:bottomsheet-commons:%%version%%' // optional
}
```
##Getting Started
Get started by wrapping your layout in a `BottomSheetLayout`. So if you currently have this:
```xml
<LinearLayout
android:id="@+id/root"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:id="@+id/view1"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
```
You would have to update it to look like this:
```xml
<com.flipboard.bottomsheet.BottomSheetLayout
android:id="@+id/bottomsheet"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/root"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:id="@+id/view1"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
</com.flipboard.bottomsheet.BottomSheetLayout>
```
Back in your activity or fragment you would get a reference to the BottomSheetLayout like any other view.
```java
BottomSheetLayout bottomSheet = (BottomSheetLayout) findViewById(R.id.bottomsheet);
```
Now all you need to do is show a view in the bottomSheet:
```java
bottomSheet.showWithSheetView(LayoutInflater.from(context).inflate(R.layout.my_sheet_layout, bottomSheet, false));
```
You could also use one of the sheet views from the commons module.
```java
bottomSheet.showWithSheetView(new IntentPickerSheetView(this, shareIntent, "Share with...", new IntentPickerSheetView.OnIntentPickedListener() {
@Override
public void onIntentPicked(IntentPickerSheetView.ActivityInfo activityInfo) {
bottomSheet.dismissSheet();
startActivity(activityInfo.getConcreteIntent(shareIntent));
}
}));
```
That's it for the simplest of use cases. Check out the [API documentation](https://github.com/Flipboard/bottomsheet/wiki/API-Documentation) to find out how to customize BottomSheet to fit your use cases.
For more examples, also see the [Recipes](https://github.com/Flipboard/bottomsheet/wiki/Recipes) wiki.
##Common Components
These are located in the optional `bottomsheet-commons` dependency and implement common use cases for bottom sheet.
Intent Picker | Menu Sheet | ImagePicker Sheet
--- | --- | ---
 |  | 
####IntentPickerSheetView
This component presents an intent chooser in the form of a BottomSheet view. Give it an intent such as a share intent and let the user choose what activity they want to share the intent with in a BottomSheet.
Example from the sample app.
```java
IntentPickerSheetView intentPickerSheet = new IntentPickerSheetView(MainActivity.this, shareIntent, "Share with...", new IntentPickerSheetView.OnIntentPickedListener() {
@Override
public void onIntentPicked(IntentPickerSheetView.ActivityInfo activityInfo) {
bottomSheet.dismissSheet();
startActivity(activityInfo.getConcreteIntent(shareIntent));
}
});
// Filter out built in sharing options such as bluetooth and beam.
intentPickerSheet.setFilter(new IntentPickerSheetView.Filter() {
@Override
public boolean include(IntentPickerSheetView.ActivityInfo info) {
return !info.componentName.getPackageName().startsWith("com.android");
}
});
// Sort activities in reverse order for no good reason
intentPickerSheet.setSortMethod(new Comparator<IntentPickerSheetView.ActivityInfo>() {
@Override
public int compare(IntentPickerSheetView.ActivityInfo lhs, IntentPickerSheetView.ActivityInfo rhs) {
return rhs.label.compareTo(lhs.label);
}
});
bottomSheet.showWithSheetView(intentPickerSheet);
```
####MenuSheetView
This component presents a BottomSheet view that's backed by a menu. It behaves similarly to the new `NavigationView` in the Design support library, and is intended to mimic the examples in the Material Design spec. It supports list and grid states, with the former adding further support for separators and subheaders.
Example from the sample app.
```java
MenuSheetView menuSheetView =
new MenuSheetView(MenuActivity.this, MenuSheetView.MenuType.LIST, "Create...", new MenuSheetView.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(MenuActivity.this, item.getTitle(), Toast.LENGTH_SHORT).show();
if (bottomSheetLayout.isSheetShowing()) {
bottomSheetLayout.dismissSheet();
}
return true;
}
});
menuSheetView.inflateMenu(R.menu.create);
bottomSheetLayout.showWithSheetView(menuSheetView);
```
