Google introduced official bottomsheets implementation in Support library 23.2.0,thus this library is no longer activly being developed. I will continuely fix defects been found and accept good PR but No more new feature will be developed. Thanks for your support!

One way to present a set of actions to a user is with bottom sheets, a sheet of paper that slides up from the bottom edge of the screen. Bottom sheets offer flexibility in the display of clear and simple actions that do not need explanation.

This library works on android api 14+

• Download this library, import to your IDE (eclipse...) as a library project.
• Using Gradle

    compile 'com.cocosw:bottomsheet:1.+@aar'

• Using Maven

<dependency>
    <groupId>com.cocosw</groupId>
    <artifactId>bottomsheet</artifactId>
    <version>1.x</version>
    <type>apklib</type>
</dependency>

• Version if you use Android support library - 1.4.0 if you use Androidx - 1.5.0

• Define actions in menu xml (Tip: divider tag has been replaced by group tag from 1.1.0)

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/share" android:title="@string/share" android:icon="@drawable/perm_group_messages"/>
    <item android:id="@+id/upload" android:title="@string/upload" android:icon="@drawable/perm_group_system_clock"/>
    <item android:id="@+id/call" android:title="@string/call" android:icon="@drawable/perm_group_phone_calls"/>
    <group android:id="@+id/helpgroup">
         <item android:id="@+id/help" android:title="@string/help" android:icon="@drawable/perm_group_system_tools"/>
    </group>
</menu>

• Show it just like showing a dialog.

new BottomSheet.Builder(this).title("title").sheet(R.menu.list).listener(new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        switch (which) {
                            case R.id.help:
                                q.toast("Help me!");
                                break;
                        }
                    }
                }).show();

• You can also add action items in builder.

You can get a menu object from bottomsheet instance from 1.1.0, and change it as you want, exactly like you're manipulating an android menu or actionbar actionitems. Please be aware that if you change the menu after showing the bottomsheet, you must call invalidate(), or no changes will be applied and your app might crash. Please check example application for more info.

• Invoke darkTheme() to show the built-in dark theme
• Or define your style in your application, and call bottomsheet by using new BottomSheet.Builder(this,R.style.BottomSheet_StyleDialog)....

    <style name="BottomSheet.StyleDialog" parent="BottomSheet.Dialog">
        <item name="android:backgroundDimAmount">0.5</item>
        <item name="android:windowAnimationStyle">@style/BottomSheet.Animation</item>
        <item name="android:textColorPrimary">#DDffffff</item>
        <item name="android:textColorSecondary">#8Affffff</item>
        <item name="android:textColorHint">#42ffffff</item>
        <item name="bs_dialogBackground">@color/abc_search_url_text_normal</item>
        <item name="bs_dividerColor">@color/abc_search_url_text_pressed</item>
        <item name="bs_numColumns">4</item>
        <item name="bs_listStyle">@style/BottomSheet.StyleList</item>
    </style>

• Or set bottomesheet style in your activity theme

    <style name="StyleTheme" parent="Theme.AppCompat">
        <item name="bs_bottomSheetStyle">@style/BottomSheet.StyleDialog</item>
    </style>

• Feel free to fork it
