单击行时无法转到新活动
我一直试图让单击TextView时出现一个选项菜单。我已经能够做到这一点。但是现在当我单击该行时，我无法进入下一个活动。
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
popup.show();
}
});
}
/*int leagueId = leaguesList.get(position).getId();
Intent myIntent = new Intent(MainActivity.this, BowlerActivity.class);
myIntent.putExtra("leagueId", leagueId);
startActivity(myIntent);
overridePendingTransition(0, 0);*/
@Override
public void onRowClick(View view, int position) {
int leagueId = leaguesList.get(position).getId();
Intent myIntent = new Intent(MainActivity.this, BowlerActivity.class);
myIntent.putExtra("leagueId", leagueId);
startActivity(myIntent);
overridePendingTransition(0, 0);
}
@Override
public void onLongClick(View view, int position) {
showActionsDialog(position);
}
}));
}
RecyclerTouchListener.java
public class RecyclerTouchListener implements RecyclerView.OnItemTouchListener {
private ClickListener clicklistener;
private GestureDetector gestureDetector;
public RecyclerTouchListener(Context context, final RecyclerView recycleView, final ClickListener clicklistener) {
this.clicklistener = clicklistener;
gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
@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)) {
clicklistener.onClick(child, rv.getChildAdapterPosition(child));
}
return false;
}
@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
public interface ClickListener {
void onClick(View view, int position);
void onRowClick(View view, int position);
void onLongClick(View view, int position);
}
}
我在该网站上搜索了许多不同的文章，并尝试了会员发布的几种不同的解决方案，但仍然无法进行新的活动。
如何创建onClickListener（）来侦听主行和TextView上的单击。
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 "";
}
}
我已经能够通过将onClick（）设置为在TextView上激活来使其工作。这是不理想的，因为我似乎不得不双击文本才能切换活动。
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
public void onClick(View view, final int position) {
TextView buttonViewOption = (TextView) view.findViewById(R.id.textViewOptions);
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
popup.show();
}
});
}
@Override
public void onLongClick(View view, int position) {
showActionsDialog(position);
}
}));
}
我的listview xml文件：
<?xml version="1.0" encoding="utf-8"?>

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

您需要创建一个自定义适配器类
BowlerAdapter.java
public class BowlerAdapter extends RecyclerView.Adapter<BowlerAdapter.MyViewHolder> {
private LayoutInflater inflater;
List<Bowler> data= Collections.emptyList();
public BowlerAdapter(Context context, List<BowlerAdapter> data) {
inflater= LayoutInflater.from(context);
this.data=data;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view=inflater.inflate(R.layout.layout_recycler_view_single, parent, false);
MyViewHolder holder=new MyViewHolder(view);
return holder;
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
BowlerAdapter current=data.get(position);
holder.header.setText(current.header);
holder.image.setImageResource(current.image);
//.....
}
@Override
public int getItemCount() {
return data.size();
}
class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
CTextView header;
ImageView image;
public MyViewHolder(View itemView) {
super(itemView);
header= (CTextView) itemView.findViewById(R.id.aap_tv_header);
image= (ImageView) itemView.findViewById(R.id.aap_img_dog_s);
itemView.setOnClickListener(this);
}
@Override
public void onClick(View view) {
int pos = getAdapterPosition();
BowlerAdapter current=data.get(pos);
//Now here you can either use switch case or if statement to perform action on the basis of position
}
}
}
在MainActivity.java
@Nullable
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView=(RecyclerView) fragView.findViewById(R.id.rv);
adapter=new BowlerAdapter(getActivity(),getData());
recyclerView.setAdapter(adapter);
LinearLayoutManager llm=new LinearLayoutManager(getActivity());
recyclerView.setLayoutManager(llm);
}
public List<Bowler> getData(){
//Here you will return your ArrayList<Bowler>
}
在activity_main.xml中
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/f1LinearLayout"
android:orientation="vertical"
>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/rv">
</android.support.v7.widget.RecyclerView>
</LinearLayout>
这只是示例代码。因此，您可以在此处实现逻辑。也可以有其他方式。
答案 1 :(得分：1)
解决方案：
删除recyclerview.onTouchListener... ..我们不再需要它。
holder对象上的click侦听器比这更好。请参见下面的以下示例：
类似于holder.bowlerLeagueId.setText(bowler.getLeagueId());，您还可以编写：
holder.bowlerLeagueId.setOnClickListener(....) {
........ (Write here)
}
然后，在您的东西（在此处写）中，编写代码以导航至下一个活动。
类似地，您可以对任何holder.viewid.setOnClick等执行此操作。
希望有帮助。
答案 2 :(得分：0)
我可以知道您是否在清单文件中注册了BowlerActivity吗？请在点击视图后附加日志。
我看到您初始化了本地侦听器并实现了onLongClick和onTouch，但是您未设置的视图没有将OnClick事件设置为OnRowClick并转移到自定义的侦听器回调
