OnItemClick不工作

Question

我创建了一个自定义类，它包含ArrayList的参数、片段的容器和片段的类。

就像你看到的：

​

package com.example.android.testeclickitem;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class CustomClass {

    private int mImage;

    private String mName;

    private String mLocalization;

    private static int mFragmentI;

    private static int mFragmentII;

    private static int mFragmentIII;

    public CustomClass (int image, String name, String localization, int fragmentI, int fragmentII, int fragmentIII){
        mImage = image;
        mName = name;
        mLocalization = localization;
        mFragmentI = fragmentI;
        mFragmentII = fragmentII;
        mFragmentIII = fragmentIII;
    }

    public int getImage() {
        return mImage;
    }

    public void setImage(int mImage) {
        this.mImage = mImage;
    }

    public String getName() {
        return mName;
    }

    public void setName(String mName) {
        this.mName = mName;
    }

    public String getLocalization() {
        return mLocalization;
    }

    public void setLocalization(String mLocalization) {
        this.mLocalization = mLocalization;
    }

    public static int getFragmentI() {return mFragmentI;}

    public  void setFragmentI(int mFragmentI) {
        this.mFragmentI = mFragmentI;
    }

    public static int getFragmentII() {
        return mFragmentII;
    }

    public void setFragmentII(int mFragmentII) {
        this.mFragmentII = mFragmentII;
    }

    public static int getFragmentIII() {
        return mFragmentIII;
    }

    public void setFragmentIII(int mFragmentIII) {
        this.mFragmentIII = mFragmentIII;
    }

    public static class FragmentInflaterI extends Fragment {

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
            return inflater.inflate(getFragmentI(), container, false);
        }
    }

    public static class FragmentInflaterII extends Fragment {

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
            return inflater.inflate(getFragmentII(), container, false);
        }
    }

    public static class FragmentInflaterIII extends Fragment {

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
            return inflater.inflate(getFragmentIII(), container, false);
        }
    }

    static class Fragments extends FragmentPagerAdapter {

        public Fragments (android.support.v4.app.FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {
            if (position == 0) {
                return new FragmentInflaterI();
            } else if (position == 1){
                return new FragmentInflaterII();
            } else {
                return new FragmentInflaterIII();
            }
        }

        @Override
        public int getCount() {
            return 3;
        }
    }

    public static class Container extends AppCompatActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            // Set the content of the activity to use the activity_main.xml layout file
            setContentView(R.layout.layout_container);

            // Find the view pager that will allow the user to swipe between fragments
            ViewPager viewPager = (ViewPager) findViewById(R.id.layout_container);

            // Create an adapter that knows which fragment should be shown on each page
            Fragments adapter = new Fragments(getSupportFragmentManager());

            // Set the adapter onto the view pager
            viewPager.setAdapter(adapter);
        }
    }
}

​

在主类中，我添加了ArrayList和OnItemClickListener，目的是打开容器和片段：

​

package com.example.android.testeclickitem;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;

import java.util.ArrayList;

import static com.example.android.testeclickitem.CustomClass.Container;

public class Hoteis extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_hoteis);

        final ArrayList <CustomClass> lista = new ArrayList<>();
        CustomClass hoteis = new CustomClass(0, "", "", 0, 0, 0);
        hoteis.setImage(R.mipmap.ic_hotel_white_48dp);
        hoteis.setName(getString(R.string.name_hotel));
        hoteis.setLocalization(getString(R.string.local_hotel));
        hoteis.setFragmentI(R.layout.fragment_hotel1_perfil);
        hoteis.setFragmentII(R.layout.fragment_hotel1_preco);
        hoteis.setFragmentIII(R.layout.fragment_hotel1_contato);
        lista.add(hoteis);

        CustomClass hoteis2 = new CustomClass(0, "", "", 0, 0, 0);
        hoteis2.setImage(R.mipmap.ic_hotel_white_48dp);
        hoteis2.setName(getString(R.string.name_hotel2));
        hoteis2.setLocalization(getString(R.string.local_hotel2));
        hoteis.setFragmentI(R.layout.fragment_hotel2_perfil);
        hoteis.setFragmentII(R.layout.fragment_hotel2_preco);
        hoteis.setFragmentIII(R.layout.fragment_hotel2_contato);
        lista.add(hoteis2);

        CustomClassAdapter itemAdapter = new CustomClassAdapter(this, lista);

        ListView listView = (ListView) findViewById(R.id.lista_hoteis);

        listView.setAdapter(itemAdapter);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {

                Intent openFragment = new Intent(Hoteis.this, Container.class);
                startActivity(openFragment);
            }
        });
    }
}

​

问题是:单击列表中的任何项目时，都要使用已声明的持久片段--而不是在各个单击项上声明的片段。

我试着：

CustomClass customClass = list.get(position);

和

Intent openFragment = new Intent(Hoteis.this, Container.class);
startActivity(openFragment);

但不管用。

有谁知道如何做"OnItemClick“来识别这个职位吗？

Answer 1

我想是因为你的碎片被宣布为静态的。由于静态的属性，您的片段在所有CustomClass实例中都是相同的。您应该阅读静态关键字这里。
