swipe right to display drawer with flowing effects.

Include the following dependency in your build.gradle file.

Gradle:

    repositories {
        jcenter()
    }

    dependencies {
        compile 'com.mxn.soul:flowingdrawer-core:1.2.5'
        compile 'com.nineoldandroids:library:2.4.0'
    }

add onOpenMenu and onCloseMenu event Listener to catch open and close event . Add these two method in MyMenuFragment extends MenuFragment.

For a working implementation of this project see the app/ folder.

MainActivity:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
           ....
        mLeftDrawerLayout = (LeftDrawerLayout) findViewById(R.id.id_drawerlayout);
        FragmentManager fm = getSupportFragmentManager();
        MyMenuFragment mMenuFragment = (MyMenuFragment) fm.findFragmentById(R.id.id_container_menu);
        FlowingView mFlowingView = (FlowingView) findViewById(R.id.sv);
        if (mMenuFragment == null) {
            fm.beginTransaction().add(R.id.id_container_menu, mMenuFragment = new MyMenuFragment()).commit();
        }
        mLeftDrawerLayout.setFluidView(mFlowingView);
        mLeftDrawerLayout.setMenuFragment(mMenuFragment);
        ...
    }

activity_main.xml:

    <com.mxn.soul.flowingdrawer_core.LeftDrawerLayout
        android:id="@+id/id_drawerlayout"

                android:layout_width="match_parent"
                android:layout_height="match_parent"/>
            <FrameLayout
                android:id="@+id/id_container_menu"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_alignParentLeft="true"
                android:layout_marginRight="25dp"
                android:paddingRight="10dp"
                />
        </RelativeLayout>

    </com.mxn.soul.flowingdrawer_core.LeftDrawerLayout>

• use LeftDrawerLayout as the root of xml.

• The root has two child, first for content,second for menu.

• menu'root alse has two child , first for FlowingView to display flowing effects,second for fragment .

• fragment need to has a 'marginRight', for example 25dp. marginRight here is important . 'marginRight' have effect on drawer's elasticity. The more 'marginRight' is the more elastic. Try to set '10dp', '25dp' ,'50dp' to see the difference.

• make the fragment of menu extends MenuFragment.

• pay attention to MenuFragment's onCreateView: return setupReveal(root) ;

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
            View view = inflater.inflate(R.layout.fragment_menu, container,
                    false);
            .......
            return  setupReveal(view) ;
        }

• in MenuFragment'xml ,add 'android:background="@android:color/transparent" '

• in MainActivity,use

mMenuFragment = new MyMenuFragment();
mLeftDrawerLayout.setFluidView(mFlowingView);
mLeftDrawerLayout.setMenuFragment(mMenuFragment);

in order .

• you can call mLeftDrawerLayout.closeDrawer() and mLeftDrawerLayout.openDrawer() to close or open drawer automatically.

• change background color for drawer by "paint_color" in colors.xml.This is not a good way,and will be improved in the next version.

• use spring dynamics models to make more bouncing effects.
• close by touch effect need to enhance.
• improve the lines to be smoother when open and close drawer.
• some part of the code need to simplify.

First of all, thank you ! As you see ,the project is not as good as the original design sketch and thank you for watch and star. At present we still have a lot of things to do . I would love to get some help on the TODO list .So if you find a bug in the library or want a feature and think you can fix it yourself,fork + pull request and i will greatly appreciate it!
