1、效果图展示

2、实现思路
实现配置：
1）自定义的GridView
2）自定义的TabLayout（需求中要求下划线比字体短）
3）自定义的ScrollView实现流程：
每一个Tag 标签对应着一个布局，也就是自定义的GridView（因为需要计算高度），把每一个Tag 标签布局对应着一层，计算每一层的高度，然后区分手势滑动以及通过TabLayout的Tab选择，在ScrollView中移动布局即可
3、自定义的TabLayout

tab_item_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

4、自定义的GridView
MyGridView.java
public class MyGridView extends GridView {
public MyGridView(android.content.Context context,
android.util.AttributeSet attrs) {
super(context, attrs);
}
/**
* 设置不滚动
*/
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
}
5、自定义的ScrollView
ObservableScrollView.java
public class ObservableScrollView extends ScrollView {
private ScrollViewListener scrollViewListener = null;
public ObservableScrollView(Context context) {
super(context);
}
public ObservableScrollView(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
}
public ObservableScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public void setScrollViewListener(ScrollViewListener scrollViewListener) {
this.scrollViewListener = scrollViewListener;
}
@Override
protected void onScrollChanged(int x, int y, int oldx, int oldy) {
super.onScrollChanged(x, y, oldx, oldy);
if (scrollViewListener != null) {
scrollViewListener.onScrollChanged(this, x, y, oldx, oldy);
}
}
public interface ScrollViewListener {
void onScrollChanged(ObservableScrollView scrollView, int x, int y, int oldx, int oldy);
}
}
6、完整实现代码如下
item_function_content_first.xml、 item_function_content_second.xml、item_function_content_third.xml、item_function_content_fourth.xml的布局代码基本是一样，不过需要注意的是：最后一层加了一个有高度的空布局

应该涉及到了ViewPager两个Fragment之间的切换和通信，如下所示：

通过TabMainFuntionFragment和 TabMainHomeFragment 它们的依赖容器 MainActivity，实现值传递，配置如下所示：
TabMainFuntionFragment.java
private void setFunctionIndexFromHomeFragment(){
MainActivity activity = (MainActivity) getActivity();
boolean isOnclickFunc = activity.isOnclickFunc;
int funcIndex = activity.funcIndex;
currentPosition = funcIndex;
LogUtils.d("setFunctionIndexFromHomeFragment========currentPosition============="+currentPosition);
LogUtils.d("isOnclickFunc============="+isOnclickFunc);
LogUtils.d("funcIndex============="+funcIndex);
smoothScrollByPositon(currentPosition);
}
TabMainHomeFragment.java
private void jumpToTabMainFunctionFragment(int position){
LogUtils.d("jumpToTabMainFunctionFragment===================");
MainActivity activity = (MainActivity) getActivity();
activity.funcIndex = position;
activity.isOnclickFunc = true;
LogUtils.d("activity.funcIndex==================="+activity.funcIndex);
LogUtils.d("activity.isOnclickFunc==================="+activity.isOnclickFunc);
activity.mViewPager.setCurrentItem(1);
}
MainActivity.java
public int funcIndex = 0;
public boolean isOnclickFunc = false;
