CoordinatorTabLayout

CoordinatorTabLayout是一个自定义组合控件,可快速实现TabLayout与CoordinatorLayout相结合的样式继承至CoordinatorLayout, 在该组件下面使用了CollapsingToolbarLayout包含TabLayout。

这里写图片描述

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
这里写图片描述

在使用它的界面添加以下设置:

setTitle(String title) :设置Toolbar标题
setupWithViewPager(ViewPager viewPager) :将写好的viewpager设置到该控件当中
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);

更多功能

添加折叠后的颜色变化效果
这里写图片描述

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

获取子控件
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

属性

app:contentScrim -> color.默认为?attr/colorPrimary
app:tabIndicatorColor -> color.
