Question

我有水平的Recyclerview，想要禁用它的手动滚动。但是点击项目时应滚动。怎么做？

Answer 1

在你的电话中实施RecyclerView.OnItemTouchListener它会在recyclerview上偷走所有触摸事件

public class RecyclerViewDisabler implements RecyclerView.OnItemTouchListener {

@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
    return true;
}

@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {

}

@Override
public void onRequestDisallowInterceptTouchEvent(boolean) {

}
}

启用和禁用滚动：

RecyclerView recycleview = ...
RecyclerView.OnItemTouchListener disabler = new RecyclerViewDisabler();

recycleview.addOnItemTouchListener(disabler);    // scolling disable
// do what you want to do  at time of disable scrolling
recycleview.removeOnItemTouchListener(disabler); // scrolling enabled again

Answer 2

// You can set `onTouchListener`

public class RecyclerViewTouch implements RecyclerView.OnItemTouchListener {

    @Override
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
        return true;
    }

    @Override
    public void onTouchEvent(RecyclerView rv, MotionEvent e) {

    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
}

// Use it
RecyclerView.OnItemTouchListener disable = new RecyclerViewTouch();
rView.addOnItemTouchListener(disable);        // disables scolling
rView.removeOnItemTouchListener(disable);     // enable the scrolling

Answer 3

您必须为此创建自定义布局管理器，您可以通过这种方式禁用滚动

示例：

public class CustomLayoutManager extends LinearLayoutManager { private boolean isScrollEnabled = true; public CustomLayoutManager(Context context) { super(context); } public void setScrollEnabled(boolean flag) { this.isScrollEnabled = flag; } @Override public boolean canScrollHorizontally() { //Similarly you can customize "canScrollVertically()" for managing horizontal scroll return isScrollEnabled && super.canScrollHorizontally(); }
这样你可以禁用手动滚动

感谢Emi Raz。他的回答对于在 recyclerview 上禁用滚动行为非常简单。解决方案对我有用。请参阅他的解决方案here

Java：

LinearLayoutManager lm = new LinearLayoutManager(getContext()) {
    @Override
    public boolean canScrollVertically() {
        return false;
    }
};

科特林：

val lm: LinearLayoutManager = object : LinearLayoutManager(requireContext()) {
    override fun canScrollVertically(): Boolean { return false }
}
