javascript - 单击行时无法转到新 Activity

Question

我一直试图在单击 TextView 时显示一个选项菜单。我已经能够做到这一点。但是现在，当我单击该行时，我无法进入下一个 Activity 。

这是我在 MainActivity 中的代码

//On Long Click On The RecyclerView Item An Alert Dialog Is Opened With The Option To Choose Edit/Delete
        recyclerView.addOnItemTouchListener(new RecyclerTouchListener(this, recyclerView, new RecyclerTouchListener.ClickListener() {
            @Override
            public void onClick(View view, final int position) {
                TextView buttonViewOption = (TextView) view.findViewById(R.id.textViewOptions);
                TextView rowItem = (TextView) view.findViewById(R.id.rowItem);
                buttonViewOption.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View view) {

                        //creating a popup menu
                        PopupMenu popup = new PopupMenu(MainActivity.this, buttonViewOption);
                        //inflating menu from xml resource
                        popup.inflate(R.menu.options_menu);
                        //adding click listener
                        popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                            @Override
                            public boolean onMenuItemClick(MenuItem item) {
                                switch (item.getItemId()) {
                                    case R.id.menu1:
                                        //handle menu1 click
                                        break;
                                    case R.id.menu2:
                                        break;
                                    case R.id.menu3:
                                        showLeagueDialog(true, leaguesList.get(position), position);
                                        break;
                                    case R.id.menu4:
                                        deleteLeague(position);
                                        break;
                                }
                                return false;
                            }
                        });
                        //displaying the popup

                    }
                });
            }
               /*int leagueId = leaguesList.get(position).getId();

RecyclerTouchListener.java

public class RecyclerTouchListener implements RecyclerView.OnItemTouchListener {

    private ClickListener clicklistener;
    private GestureDetector gestureDetector;

    public RecyclerTouchListener(Context context, final RecyclerView recycleView, final ClickListener clicklistener) {

            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }

            @Override
            public void onLongPress(MotionEvent e) {
                View child = recycleView.findChildViewUnder(e.getX(), e.getY());
                if (child != null && clicklistener != null) {
                    clicklistener.onLongClick(child, recycleView.getChildAdapterPosition(child));
                }
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
        View child = rv.findChildViewUnder(e.getX(), e.getY());
        if (child != null && clicklistener != null && gestureDetector.onTouchEvent(e)) {

我在该网站上搜索了许多不同的文章，并且尝试了成员发布的几种不同的解决方案，但我仍然无法进行新的 Activity 。

如何创建一个 onClickListener() 来监听主行上的点击以及 TextView。

任何帮助将不胜感激。

BolwerAdapter.java

public class BowlerAdapter extends RecyclerView.Adapter<BowlerAdapter.MyViewHolder> {

    private List<Bowler> bowlersList;

    public void notifyDatasetChanged(List<Bowler> newbowlerlist) {
        bowlersList.clear();
        bowlersList.addAll(newbowlerlist);
        super.notifyDataSetChanged();
    }

    public class MyViewHolder extends RecyclerView.ViewHolder {
        private TextView bowlerLeagueId;
        private TextView name;
        private TextView bowlerAverage;
        private TextView bowlerHandicap;
        private TextView timestamp;

        MyViewHolder(View view) {
            super(view);
            bowlerLeagueId = view.findViewById( R.id.tvLeagueId);
            name = view.findViewById(R.id.tvBowlerName);
            bowlerAverage = view.findViewById(R.id.tvBowlerAverage);
            bowlerHandicap = view.findViewById(R.id.tvBowlerHandicap);
            timestamp = view.findViewById(R.id.timestamp);
        }
    }

    BowlerAdapter(Context context, List<Bowler> bowlersList) {
        this.bowlersList = bowlersList;
    }

    @NonNull
    @Override
    public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from( Objects.requireNonNull( parent ).getContext())
                .inflate(R.layout.listview_bowler, parent, false);

        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
        Bowler bowler = bowlersList.get(position);

        holder.bowlerLeagueId.setText(bowler.getLeagueId());
        holder.name.setText(bowler.getName());
        if (bowler.getAverage() != "") {
            holder.bowlerAverage.setText(String.format("Bowler Avg: %s", bowler.getAverage()));
        } else {
            holder.bowlerAverage.setText(String.format("Bowler Avg: %s", "0"));
        }
        Integer handicap = Integer.parseInt(bowler.getHandicap());
        if (handicap < 0) {
            holder.bowlerHandicap.setText(String.format("Bowler Handicap: %s", "0"));
        }
        if (bowler.getHandicap() != "" ){
            holder.bowlerHandicap.setText(String.format("Bowler Handicap: %s", bowler.getHandicap()));
        } else {
            holder.bowlerHandicap.setText(String.format("Bowler Handicap: %s", "0"));
        }
        //Formatting And Displaying Timestamp
        holder.timestamp.setText(formatDate(bowler.getTimestamp()));
    }

    @Override
    public int getItemCount() {
        return bowlersList.size();
    }

    //Formatting TimeStamp to 'EEE MMM dd yyyy (HH:mm:ss)'
    //Input  : 2018-05-23 9:59:01
    //Output : Wed May 23 2018 (9:59:01)
    private String formatDate(String dateStr) {
        try {
            SimpleDateFormat fmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            Date date = fmt.parse(dateStr);
            SimpleDateFormat fmtOut = new SimpleDateFormat("EEE MMM dd yyyy (HH:mm:ss)");
            return fmtOut.format(date);
        } catch (ParseException ignored) { }

        return "";
    }
}

我已经能够通过设置 onClick() 在 TextView 上激活来使其工作。这并不理想，因为我似乎必须双击文本才能切换 Activity 。

我在MainActivity中的代码

recyclerView.addOnItemTouchListener(new RecyclerTouchListener(this, recyclerView, new RecyclerTouchListener.ClickListener() {

            @Override
            public void onRowClick(View view, int position) {
                TextView listviewClick = (TextView) view.findViewById(R.id.tvSeriesName);
                listviewClick.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        int leagueId = leaguesList.get(position).getId();
                        Intent myIntent = new Intent(MainActivity.this, BowlerActivity.class);
                        myIntent.putExtra("leagueId", leagueId);
                        startActivity(myIntent);
                        overridePendingTransition(0, 0);
                    }
                });
            }

                    @Override

                                        break;
                                }
                                return false;

但是当我使用RelativeLayout listviewClick = view.findViewById(R.id.rowItem);我只能单击该行，而不能单击选项菜单。

Answer 1

解决方案:

删除recyclerview.onTouchListener... ..我们不再需要这个了。

点击 holder 上的监听器对象的效果比这更好。请参阅下面的示例:

类似于holder.bowlerLeagueId.setText(bowler.getLeagueId());你也可以写:

holder.bowlerLeagueId.setOnClickListener(....) {
     ........ (Write here)
}

然后，在您的(在此处写入)内容中编写代码以导航到下一个 Activity 。

同样，您可以对任何holder.viewid.setOnClick 等执行此操作。

希望有帮助。
