            Intent myIntent = new Intent(getActivity(), NextActivity.class);

}

}

Answer 1

只需这样做：

 listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {

               /* do what you want here, like changing fragment */
            }
        });

现在您可以使用它来加载下一页。

如果您在我的情况下，如果您使用相同的列表模板，我建议使用该捆绑包知道如何填写您的列表视图，以及要更改的监听器。

例如，如果我想访问所选国家/地区的州名单，我就可以访问包含某些国家/地区的列表视图的下一页：

Bundle bundle = new Bundle();
                bundle.putString("type", "state");
                bundle.putString("value", ((TextView) arg1).getText().toString());
                FragmentManager fm = getActivity().getSupportFragmentManager();
                FragmentTransaction fragmentTransaction = fm.beginTransaction();
                AlphabeticalListViewFragment liste = new AlphabeticalListViewFragment();
                liste.setArguments(bundle);
                fragmentTransaction.replace(android.R.id.content, liste, "listfragment");
                fragmentTransaction.addToBackStack(liste.getClass().getName());
                fragmentTransaction.commit();

然后只需阅读您的捆绑包即可知道如何填写您的列表：

    Bundle bundle = this.getArguments();
String typeListe= bundle.getString("type", "country");
if(typeListe.equals("country"))
        {...

如果您使用的是片段，则必须使用 getActivity()代替CurrentActivity.this

import android.widget.AdapterView;



 public class FragMent1 extends Fragment {

        private String arry[] = { "Tofeeq", "Ahmad", "Fragment", "Example",
                "Tofeeq", "Ahmad", "Fragment", "Example" };

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {

    View root = (LinearLayout) inflater.inflate(R.layout.yourlayout, container, false);

  ListView lv = (ListView)view.findViewById(R.id.listviewid);
            ArrayAdapter<String> array = new ArrayAdapter<String>(getActivity(),
                    android.R.layout.simple_list_item_1);
            for (String str : arry)
                array.add(str);
            lv.setAdapter(array);


      lv.setOnItemClickListener(new OnItemClickListener() {
                    public void onItemClick(AdapterView<?> parent, View view,
                            int position, long id) {

                  Intent myIntent = new Intent(getActivity(), NextActivity.class);
                  startActivity(myIntent);
                    }
                });

    return root;
        }
    }

listviewid是您在Layout中设置的ListView ID。 yourlayout yourlayout.xml？

在清单文件中添加新活动：在<application>标记内

<application>
     <activity android:label="@string/app_name" android:name="NextActivity"/>
</application>

将此ListView添加到xml

<RelativeLayout 
xmlns:android="schemas.android.com/apk/res/android";
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:background="@drawable/bg" 
android:id="@+id/yourlayout"> 


 <ListView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/listviewid"
            android:layout_gravity="center_horizontal"
            android:choiceMode="singleChoice"
            android:fastScrollEnabled="true"/>

</RelativeLayout>

  public class Fragment1 extends Fragment {

        private String arry[] = { "Tofeeq", "Ahmad", "Fragment", "Example",
                "Tofeeq", "Ahmad", "Fragment", "Example" };

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {

    View view = (LinearLayout) inflater.inflate(R.layout.yourlayout, container, false);

  ListView lv = (ListView)view.findViewById(R.id.listviewid);
            ArrayAdapter<String> array = new ArrayAdapter<String>(getActivity(),
                    android.R.layout.simple_list_item_1);
            for (String str : arry)
                array.add(str);
            lv.setAdapter(array);


      lv.setOnItemClickListener(new OnItemClickListener() {
                    public void onItemClick(AdapterView<?> parent, View view,
                            int position, long id) {

                  Intent myIntent = new Intent(CurrentActivity.this, NextActivity.class);
                  CurrentActivity.this.startActivity(myIntent);
                    }
                });

    return view;
        }

    }

在清单文件中添加新活动：

<activity android:label="@string/app_name" android:name="NextActivity"/>

Answer 4

您需要 ListView.OnItemClickListener

https://developer.android.com/reference/android/widget/AdapterView.OnItemClickListener.html

实现侦听器并确定侦听器方法中的位置参数单击了哪个侦听器。

android：使用片段在listview中的onclick事件
