RecyclerView中,我制作了一个带有搜索栏和播放按钮的歌曲列表。

在搜索栏中,使用线程

移动音乐当前位置

但改变活动,音乐停止但错误

我希望当我改变活动时,音乐停止而不是错误

线程只能在Activity或Fragment中被杀死。使用此类覆盖您的recyclerview点击侦听器。

创建新的java文件并将其命名为RecyclerItemClickListener.java

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
    private OnItemClickListener mListener;

    public interface OnItemClickListener {
        void onItemClick(View view, int position);
    }

    private GestureDetector mGestureDetector;

    public RecyclerItemClickListener(Context context, OnItemClickListener listener) {
        mListener = listener;
        mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
        View childView = view.findChildViewUnder(e.getX(), e.getY());
        if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
            mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
        }
        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) { }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
        // do nothing
    }
}

在您的活动/片段

yourRecyclerviewId.addOnItemTouchListener(new RecyclerItemClickListener(this, new RecyclerItemClickListener.OnItemClickListener() {
       @Override
       public void onItemClick(View view1, int position) {
           //view1 - is clicked view
           //position - position of the clicked list

           //put your method in here

       }
}));

现在,您可以使用OnPause()和OnStop()方法来终止线程或服务
