onclicklistener不工作從導航抽屜裏的片段

Question

我無法弄清楚我做錯了什麼。我有一個導航抽屜的設置，當我點擊導航抽屜中的其中一個項目時，它會加載我使用適配器自定義的列表視圖的一個片段。那部分工作。

但我在該片段內添加了一個onclicklistener，點擊時我想加載一個新片段。但是當我點擊列表視圖中的項目時，什麼都不會發生。 這是我的代碼。

這是EventsFragment.java，這是加載自定義列表視圖。

package org.nctta.nctta_tournaments.fragments; 

import android.app.Fragment; 
import android.os.Bundle; 
import android.support.annotation.Nullable; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ListView; 
import android.widget.AdapterView; 

import org.nctta.nctta_tournaments.R; 
import org.nctta.nctta_tournaments.Tournament; 
import org.nctta.nctta_tournaments.TournamentAdapter; 

import java.util.ArrayList;

public class EventsFragment extends Fragment { 

public EventsFragment() { 
    //Required empty public constructor 
} 

View myView; 

@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) { 
    myView = inflater.inflate(R.layout.events_layout, container,false); 

    //create a list of tournaments for testing 
    final ArrayList<Tournament> Tournaments = new ArrayList<Tournament>(); 
     Tournaments.add(new Tournament("1","Ohio East Fall Tournament","1/1/2017", "1/1/2017","University of Akron")); 
     Tournaments.add(new Tournament("2","Ohio West Fall Tournament","1/1/2017", "1/1/2017","Ohio State University")); 
     Tournaments.add(new Tournament("3","Upper Midwest Fall Tournament","1/1/2017", "1/1/2017","University of Iowa")); 
     Tournaments.add(new Tournament("4","Central Plains Fall Tournament","1/1/2017", "1/1/2017","Univeristy of Centeral Plains")); 
     Tournaments.add(new Tournament("5","Lower Midwest Fall Tournament","1/1/2017", "1/1/2017","Lindenwood University")); 
     Tournaments.add(new Tournament("6","Midwest Regional Tournament","1/1/2017", "1/1/2017","Lindenwood University")); 
     Tournaments.add(new Tournament("7","Great Lakes Regional Tournament","1/1/2017", "1/1/2017","Lindenwood University")); 
     Tournaments.add(new Tournament("8","South Regional Tournament","1/1/2017", "1/1/2017","Lindenwood University")); 

    //Create an Tournament Adapter 
    TournamentAdapter adapter = new TournamentAdapter(getActivity(),Tournaments); 

    //find the listview object in the view hierarchy 
    ListView listView = (ListView) myView.findViewById(R.id.tourList); 
    listView.setAdapter(adapter); 

    //set a click listener to open tournament info page 
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> adapterView, View view, int position, long l){ 
      //get the tournament object at the given position the user clicked on 
      Tournament tournament = Tournaments.get(position); 
      //start tournamentactivity 
      android.app.FragmentManager fragmentManager = getFragmentManager(); 

      fragmentManager.beginTransaction() 
         .replace(R.id.content_frame, new TournamentFragment()) 
         .commit(); 
     } 
    }); 
    return myView; 
} 
} 

這裏是我的TournamentFragment，當一個項目被點擊時應該加載。這個片段我想加載頁面瀏覽器與標籤，我無法去工作，所以現在我評論了這些東西。只是想讓clicklistener先工作。

package org.nctta.nctta_tournaments.fragments; 

import android.app.Activity; 
import android.os.Bundle; 
import android.support.annotation.Nullable; 
import android.support.design.widget.TabLayout; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.view.ViewPager; 
import android.app.Fragment; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 

import org.nctta.nctta_tournaments.R; 

/**

*/ 

public class TournamentFragment extends Fragment { 
View myView; 
@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) { 
    myView = inflater.inflate(R.layout.tournament_tabs, container,false); 
/* 
    //Find the view pager that will allow the user to swipe between fragments 
    ViewPager viewPager = (ViewPager) myView.findViewById(R.id.viewpager); 
    //create an adapter that knows which fragment should be shown on each page 
    TournTabsAdapter adapter = new TournTabsAdapter(this, getChildFragmentManager()); 
    //set the adapter onto the view pager 
    viewPager.setAdapter(adapter); 
    //find the tab layout that shows the tabs 
    TabLayout tabLayout = (TabLayout) myView.findViewById(R.id.tabs); 
    // Connect the tab layout with the view pager. This will 
    // 1. Update the tab layout when the view pager is swiped 
    // 2. Update the view pager when a tab is selected 
    // 3. Set the tab layout's tab names with the view pager's adapter's titles 
    //  by calling onPageTitle() 
    tabLayout.setupWithViewPager(viewPager); 
*/ 
    return myView; 
} 

}

任何想法？

好的評論和一些谷歌搜索幫助我想出瞭如何讓onclicklistener工作...不知道爲什麼我的帖子downvoted ... 單擊監聽器項目沒有工作的主要原因是因爲我的列表視圖的自定義適配器包含一個imagebuttom。我最終做的是刪除該監聽器並在適配器內添加onclicklisteners。關鍵是要使用settag。

這裏是我的適配器代碼。我點擊一個敬酒信息來驗證。
