用法

Step 1

在gradle文件中加入下面的依赖:

dependencies {
    compile 'cn.hugeterry.coordinatortablayout:coordinatortablayout:1.0.6'
}

Step 2

在你自己的XML中使用它:

<cn.hugeterry.coordinatortablayout.CoordinatorTabLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/coordinatortablayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v4.view.ViewPager
        android:id="@+id/vp"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</cn.hugeterry.coordinatortablayout.CoordinatorTabLayout>

Step 3

CoordinatorTabLayout：TabLayout 和 CoordinatorLayout 相结合的折叠控件

在使用它的界面添加以下设置:

1. setTitle(String title) :设置Toolbar标题

2. setupWithViewPager(ViewPager viewPager) :将写好的viewpager设置到该控件当中

3. setImageArray(int[] imageArray) :根据tab数量设置好头部的图片数组，并传到该控件当中

//构建写好的fragment加入到viewpager中
        initFragments();
        initViewPager();
        //头部的图片数组
        mImageArray = new int[]{
                R.mipmap.bg_android,
                R.mipmap.bg_ios,
                R.mipmap.bg_js,
                R.mipmap.bg_other};

        mCoordinatorTabLayout = (CoordinatorTabLayout) findViewById(R.id.coordinatortablayout);
        mCoordinatorTabLayout.setTitle("Demo")
                .setImageArray(mImageArray)
                .setupWithViewPager(mViewPager);

大功告成，好好享用吧

添加折叠后的颜色变化效果

CoordinatorTabLayout：TabLayout 和 CoordinatorLayout 相结合的折叠控件

setImageArray(int[] imageArray, int[] colorArray) :如果你想要有头部折叠后的颜色变化，可将之前设置好的图片数组以及根据tab数量设置的颜色数组传到该控件当中

mColorArray = new int[]{
                android.R.color.holo_blue_light,
                android.R.color.holo_red_light,
                android.R.color.holo_orange_light,
                android.R.color.holo_green_light};
        mCoordinatorTabLayout.setImageArray(mImageArray, mColorArray);

添加返回

setBackEnable(Boolean canBack) :设置Toolbar的返回按钮

@Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        mCoordinatorTabLayout.setBackEnable(true);
        ...
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == android.R.id.home) {
            finish();
        }
        return super.onOptionsItemSelected(item);
    }

通过网络加载头部图片

选择用网络来加载图片。可实现以下接口: setLoadHeaderImagesListener(LoadHeaderImagesListener loadHeaderImagesListener) :设置获取头部图片的操作

@Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        mCoordinatorTabLayout.setTitle("Demo")
                .setBackEnable(true)
                .setContentScrimColorArray(mColorArray)
                .setLoadHeaderImagesListener(new LoadHeaderImagesListener() {
                    @Override
                    public void loadHeaderImages(ImageView imageView, TabLayout.Tab tab) {
                        switch (tab.getPosition()) {
                            case 0:
                                //加载图片
                                break;
                            ...
                        }
                    }
                })
                .setupWithViewPager(mViewPager);
    }

你也可以选择用Glide/Picasso等网络框架来实现，代码例子

getActionBar() :获取该组件中的ActionBar

getTabLayout() :获取该组件中的TabLayout

getImageView() :获取该组件中的ImageView
