介绍：

一个在浮动操作按钮和 Bottom Sheet之间切换的库

运行效果：

使用说明：

Gradle

Step 1. Add the jCenter repository to your project-level build.gradle file

allprojects {
  repositories {
    jcenter()
  }
}

Step 2. Add the dependency to your app-level build.gradle file:

dependencies {
   compile 'com.allattentionhere:fabulousfilter:0.0.2'
}

Create a Fragment that extends AAH_FabulousFragment:

public class MySampleFabFragment extends AAH_FabulousFragment {
    public static MySampleFabFragment newInstance() {
        MySampleFabFragment f = new MySampleFabFragment();
        return f;
    }
    @Override
    public void setupDialog(Dialog dialog, int style) {
        View contentView = View.inflate(getContext(), R.layout.filter_sample_view, null);
        RelativeLayout rl_content = (RelativeLayout) contentView.findViewById(R.id.rl_content);
        LinearLayout ll_buttons = (LinearLayout) contentView.findViewById(R.id.ll_buttons);
        contentView.findViewById(R.id.btn_close).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                closeFilter("closed");
            }
        });
        //params to set
        setAnimationDuration(600); //optional; default 500ms
        setPeekHeight(300); // optional; default 400dp
        setCallbacks((Callbacks) getActivity()); //optional; to get back result
        setViewgroupStatic(ll_buttons); // optional; layout to stick at bottom on slide
        setViewPager(vp_types); //optional; if you use viewpager that has scrollview
        setViewMain(rl_content); //necessary; main bottomsheet view
        setMainContentView(contentView); // necessary; call at end before super
        super.setupDialog(dialog, style); //call super at last
    }
}

Create view for the fragment which has parent element AAH_FilterView:

<com.allattentionhere.fabulousfilter.AAH_FilterView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <RelativeLayout
        android:id="@+id/rl_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentBottom="true"
        android:background="@color/orange"
        android:visibility="invisible"
        tools:ignore="MissingPrefix"
        tools:visibility="visible">
        <LinearLayout
            android:id="@+id/ll_buttons"
            android:layout_width="match_parent"
            android:layout_height="56dp"
            android:layout_alignParentBottom="true"
            android:background="@color/brown"
            android:orientation="horizontal"
            android:weightSum="2">
        </LinearLayout>
    </RelativeLayout>
</com.allattentionhere.fabulousfilter.AAH_FilterView>

Start the fragment on click of FloatingActionButton as below:

fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                MySampleFabFragment dialogFrag = MySampleFabFragment.newInstance();
                dialogFrag.setParentFab(fab);
                dialogFrag.show(getSupportFragmentManager(), dialogFrag.getTag());
            }
        });

Parameters

• Main View (Required)

This parameter specifies the ViewGroup of the bottom sheet to be shown after animation ends. It can be any ViewGroup(LinearLayout/FrameLayout etc):

setViewMain(relativelayout_content);

Inflated Dialog View (Required)

This parameter speicfies the inflated view for the dialog:

setMainContentView(contentDialogView);

Animation duration (Optional)

This paramter sets animation duration of translate and scale animation in milliseconds:

setAnimationDuration(600); // default 500ms

Peek Height (Optional)

This parameter sets the peek height of the bottom sheet in dp:

setPeekHeight(300); // default 400dp

• Callback (Optional)

This paramter is used to get callback from AAH_FabulousFragment to the component that called it:

setCallbacks((Callbacks) getActivity());

To use it, implement the callback in the calling component(Activity/Fragment etc), example:

public class MainSampleActivity extends AppCompatActivity implements AAH_FabulousFragment.Callbacks {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_sample);
    }
    @Override
    public void onResult(Object result) {
        Log.d("k9res", "onResult: " + result.toString());
        if (result.toString().equalsIgnoreCase("swiped_down")) {
            //do something or nothing
        } else {
            //handle result
        }
    }
}

• Static View (Optional)

This parameter is used to make view in Bottom Sheet static when user slides it. It can be any ViewGroup(LinearLayout/FrameLayout etc):

setViewgroupStatic(linearlayout_buttons);

• ViewPager (Optional)

This parameter is used to support scrolling in ViewPager as BottomSheetDialog does not support multiple views with scroll:

setViewPager(viewPager);
