在DrawerLayout Horiziontal recyclerview [英] Horiziontal recyclerview on DrawerLayout

问题描述

这是我的 NavigationView 的布局

 <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:headerLayout="@layout/header"
        app:menu="@menu/meny" />

headerLayout 具有水平<$​​ C $ C> RecyclerView 有用户可以在其上滚动的一些项目。

headerLayout has a horizontal RecyclerView which has some items that user can scroll on it.

我的问题是，每当我想在 RecyclerView 滚动，drawerLayout将会关闭。

My problem is whenever I want to scroll in RecyclerView, drawerLayout is going to close .

有没有什么办法来支持水平 RecyclerView 在 Drawerlayout ？

Is there any way to support horizontal RecyclerView on Drawerlayout?

推荐答案

你想要的是禁止对 DrawerLayout 当用户滚动在 RecyclerView ，因此，创建一个自定义的 DrawerLayout 是这样的：

What you want is disable intercepting touch event on DrawerLayout when user is scrolling on RecyclerView, So create a custom DrawerLayout like this:

public class DrawerLayoutHorizontalSupport extends DrawerLayout {

    private RecyclerView mRecyclerView;
    private NavigationView mNavigationView;

    public DrawerLayoutHorizontalSupport(Context context) {
        super(context);
    }

    public DrawerLayoutHorizontalSupport(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public DrawerLayoutHorizontalSupport(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        if (isInside(ev) && isDrawerOpen(mNavigationView))
            return false;
        return super.onInterceptTouchEvent(ev);
    }

    private boolean isInside(MotionEvent ev) { //check whether user touch recylerView or not
        return ev.getX() >= mRecyclerView.getLeft() && ev.getX() <= mRecyclerView.getRight() &&
                ev.getY() >= mRecyclerView.getTop() && ev.getY() <= mRecyclerView.getBottom();
    }

    public void set(NavigationView navigationView, RecyclerView recyclerView) {
        mRecyclerView = recyclerView;
        mNavigationView = navigationView;
    }


}

和膨胀您的布局后，只需拨打设置并通过您的 NavigationView 和 RecyclerView 。

And after inflating your layout just call set and pass your NavigationView and RecyclerView.

在 onInterceptTouchEvent 我检查是否是内部 RecyclerView 抽屉打开，用户触摸然后我返回false，那么 DrawerLayout 束手无策

In onInterceptTouchEvent i check whether is drawer open and user touch inside RecyclerView then I return false so DrawerLayout do nothing
