Android 优秀UI控件 ---- FlowingDrawer

1，前天在git上看到了一个不错的控件，最近两天项目也没有那么赶了，就抽时间来写写代码，锻炼一下手感，先看一下效果吧。

2 整体来看，主要是有两块来实现的，①主界面的RecyclerView ，②菜单栏的LeftDrawerLayout ，

先来将这个控件引到项目中，在build.gradle加入以下代码

compile 'com.mxn.soul:flowingdrawer-core:1.2.2'
compile 'com.nineoldandroids:library:2.4.0'

主界面的布局activity.xml

<?xml version="1.0" encoding="utf-8"?>

                                   xmlns:android="http://schemas.android.com/apk/res/android"
                                   xmlns:app="http://schemas.android.com/apk/res-auto"

MainActivity.java

package wangjitao.com.flowingdrawerdemo;

import android.content.Context;
import android.support.v4.app.FragmentManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.view.View;

import com.mxn.soul.flowingdrawer_core.FlowingView;
import com.mxn.soul.flowingdrawer_core.LeftDrawerLayout;

public class MainActivity extends AppCompatActivity {
    private Context mContext = MainActivity.this ;
    private RecyclerView mRecyclerView ;
    private LeftDrawerLayout mLeftDrawerLayout ;
    private FlowingView mFlowingView ;
    private MyFeedAdapter mMyFeedAdapter ;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setupToolbar();

        initView();
    }

    private void initView() {
        mLeftDrawerLayout = (LeftDrawerLayout) findViewById(R.id.lf_drawerlayout);

        //用于设置左边的drawlayout
        FragmentManager mFragmentManager = getSupportFragmentManager() ;
        MyMenuFragment mMenuFragment = (MyMenuFragment) mFragmentManager.findFragmentById(R.id.frame_container_menu);
        mFlowingView = (FlowingView) findViewById(R.id.flowingView);
        if (mMenuFragment == null) {
            mFragmentManager.beginTransaction().add(R.id.frame_container_menu, mMenuFragment = new MyMenuFragment()).commit();
        }
        mLeftDrawerLayout.setFluidView(mFlowingView);
        mLeftDrawerLayout.setMenuFragment(mMenuFragment);

        mRecyclerView = (RecyclerView) findViewById(R.id.recyclerView);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this) {
            @Override
            protected int getExtraLayoutSpace(RecyclerView.State state) {
                return 300;
            }
        });
        mMyFeedAdapter = new MyFeedAdapter(mContext);
        mRecyclerView.setAdapter(mMyFeedAdapter);

    }

    private void setupToolbar() {
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        toolbar.setNavigationIcon(R.mipmap.ic_menu_white);

        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mLeftDrawerLayout.toggle();
            }
        });

    }

    @Override
    public void onBackPressed() {
        if (mLeftDrawerLayout.isShownMenu()){
            mLeftDrawerLayout.closeDrawer();
        }else {
            super.onBackPressed();
        }
    }
}

　再看看我们关键的自定义的FragmentLayout

package wangjitao.com.flowingdrawerdemo;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.design.widget.NavigationView;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.Toast;

import com.mxn.soul.flowingdrawer_core.MenuFragment;
import com.squareup.picasso.Picasso;


public class MyMenuFragment extends MenuFragment {

    private ImageView ivMenuUserProfilePhoto;

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_menu, container,
                false);
        NavigationView mNavigationView = (NavigationView) view.findViewById(R.id.vNavigation) ;
        ivMenuUserProfilePhoto = (ImageView) mNavigationView.getHeaderView(0).findViewById(R.id
                .ivMenuUserProfilePhoto);
        setupHeader();
        return  setupReveal(view) ;
    }

    private void setupHeader() {
        int avatarSize = getResources().getDimensionPixelSize(R.dimen.global_menu_avatar_size);
        String profilePhoto = getResources().getString(R.string.user_profile_photo);
        Picasso.with(getActivity())
                .load(profilePhoto)
                .placeholder(R.drawable.img_circle_placeholder)
                .resize(avatarSize, avatarSize)
                .centerCrop()
                .transform(new CircleTransformation())
                .into(ivMenuUserProfilePhoto);
    }

    public void onOpenMenu(){


    }
    public void onCloseMenu(){


    }
}

　菜单栏中的布局文件fragment_menu.xml

    <RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.design.widget.NavigationView
            android:id="@+id/vNavigation"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:background="@android:color/transparent"
            app:headerLayout="@layout/menu_header"
            app:itemIconTint="#8b8b8b"
            app:itemTextColor="#666666"
            app:menu="@menu/drawer_menu"/>
    </RelativeLayout>

　　menu_head.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@android:color/transparent"
    android:clickable="true">
    <LinearLayout
        android:id="@+id/vGlobalMenuHeader"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <ImageView
            android:id="@+id/ivMenuUserProfilePhoto"
            android:layout_width="@dimen/global_menu_avatar_size"
            android:layout_height="@dimen/global_menu_avatar_size"
            android:layout_margin="12dp" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_weight="1"
            android:text="阿呆哥哥"
            android:textColor="#2d5d82"
            android:textSize="16sp"
            android:textStyle="bold" />

        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_margin="16dp"
            android:background="@android:color/transparent"
            android:src="@mipmap/ic_global_menu_search" />

    </LinearLayout>

    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:layout_gravity="bottom"
        android:background="#dddddd" />
</FrameLayout>

　　看一下menu_head的截图

drawer_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <group android:id="@+id/menu_group_1">
        <item
            android:id="@+id/menu_feed"
            android:icon="@mipmap/ic_global_menu_feed"
            android:title="My Feed" />
        <item
            android:id="@+id/menu_direct"
            android:icon="@mipmap/ic_global_menu_direct"
            android:title="Instagram Direct" />
        <item
            android:id="@+id/menu_news"
            android:icon="@mipmap/ic_global_menu_news"
            android:title="News" />
        <item
            android:id="@+id/menu_popular"
            android:icon="@mipmap/ic_global_menu_popular"
            android:title="Popular" />
        <item
            android:id="@+id/menu_photos_nearby"
            android:icon="@mipmap/ic_global_menu_nearby"
            android:title="Photos Nearby" />
        <item
            android:id="@+id/menu_photo_you_liked"
            android:icon="@mipmap/ic_global_menu_likes"
            android:title="Photos You've Liked" />
    </group>

    <group android:id="@+id/menu_group_2">
        <item
            android:id="@+id/menu_settings"
            android:title="Settings" />
        <item
            android:id="@+id/menu_about"
            android:title="About" />
    </group>
</menu>

到这里基本上的模型就出来了，看效果：

加上制作用户头像的圆形制作的CircleTransformation.class

package wangjitao.com.flowingdrawerdemo;

import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;

import com.squareup.picasso.Transformation;


public class CircleTransformation implements Transformation {

    private static final int STROKE_WIDTH = 6;

    @Override
    public Bitmap transform(Bitmap source) {
        int size = Math.min(source.getWidth(), source.getHeight());

        int x = (source.getWidth() - size) / 2;
        int y = (source.getHeight() - size) / 2;

        Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);
        if (squaredBitmap != source) {
            source.recycle();
        }

        Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig());

        Canvas canvas = new Canvas(bitmap);

        Paint avatarPaint = new Paint();
        BitmapShader shader = new BitmapShader(squaredBitmap, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);
        avatarPaint.setShader(shader);

        Paint outlinePaint = new Paint();
        outlinePaint.setColor(Color.WHITE);
        outlinePaint.setStyle(Paint.Style.STROKE);
        outlinePaint.setStrokeWidth(STROKE_WIDTH);
        outlinePaint.setAntiAlias(true);

        float r = size / 2f;
        canvas.drawCircle(r, r, r, avatarPaint);
        canvas.drawCircle(r, r, r - STROKE_WIDTH / 2, outlinePaint);

        squaredBitmap.recycle();
        return bitmap;
    }

    @Override
    public String key() {
        return "circleTransformation()";
    }
}

　　再加上RecyclerView的Adapter，基本上就成功了

package wangjitao.com.flowingdrawerdemo;


import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.FrameLayout;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.TextSwitcher;
import android.widget.TextView;

/**
 * Created by wangjitao on 2016/4/14.
 */
public class MyFeedAdapter extends RecyclerView.Adapter<MyFeedAdapter.MyFeedViewHolder> {
    private Context context;
    private int likeCount = 123 ;
    public MyFeedAdapter(Context context) {
        this.context = context;
    }

    @Override
    public MyFeedViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(context).inflate(R.layout.item_recyclerview, parent, false);
        return new MyFeedViewHolder(view);
    }

    @Override
    public void onBindViewHolder(final MyFeedViewHolder holder, int position) {
        if (position % 2 == 0) {
            holder.ivFeedCenter.setImageResource(R.mipmap.img_feed_sakura);
            holder.ivFeedBottom.setImageResource(R.mipmap.img_feed_bottom_1);
        } else {
            holder.ivFeedCenter.setImageResource(R.mipmap.img_feed_water);
            holder.ivFeedBottom.setImageResource(R.mipmap.img_feed_bottom_2);
        }

        holder.btnComments.setTag(position);
        holder.btnMore.setTag(position);
        holder.ivFeedCenter.setTag(holder);
        holder.btnLike.setTag(holder);

        holder.iv_likes.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                holder.tv_likes_count.setText((++likeCount)+" likes");
            }
        });
    }

    @Override
    public int getItemCount() {
        return 10;
    }

    class MyFeedViewHolder extends RecyclerView.ViewHolder {
        ImageView ivFeedCenter;
        ImageView ivFeedBottom;
        ImageButton btnComments;
        ImageButton btnLike;
        ImageButton btnMore;
        TextSwitcher tsLikesCounter;
        ImageView ivUserProfile;
        FrameLayout vImageRoot;
        ImageView iv_likes;
        TextView tv_likes_count ;

        public MyFeedViewHolder(View view) {
            super(view);

            ivFeedCenter = (ImageView) view.findViewById(R.id.ivFeedCenter);
            ivFeedBottom = (ImageView) view.findViewById(R.id.ivFeedBottom);
            btnComments = (ImageButton) view.findViewById(R.id.btnComments);
            btnLike = (ImageButton) view.findViewById(R.id.btnLike);
            btnMore = (ImageButton) view.findViewById(R.id.btnMore);
            tsLikesCounter = (TextSwitcher) view.findViewById(R.id.tsLikesCounter);
            ivUserProfile = (ImageView) view.findViewById(R.id.ivUserProfile);
            vImageRoot = (FrameLayout) view.findViewById(R.id.vImageRoot);
            iv_likes = (ImageView) view.findViewById(R.id.iv_likes);
            tv_likes_count = (TextView) view.findViewById(R.id.tv_likes_count);
        }
    }
}
