BottomSheet

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 2.1+

How to use this library

• 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>

• Compile you project with android sdk v21+

API

• Define actions in menu xml (Tip: divider tag has been replaced by group tag from 1.1.0)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

Action items manipulate

You can get a menu object from bottomsheet instance from 1.1.0, and change it as you want, exactly like you manipulating 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 would be applied and your app might crash. Please check example application for more info.

Style

• Invoke darkTheme() to show build-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="bottomSheetStyle">@style/BottomSheet.StyleDialog</item>
    </style>
