我创建了一个自定义类，其中包含ArrayList的参数，Fragments的Frag和Fragment的类。
就像你看到的那样：
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);
}
}
}
在主类上，我添加了ArrayList和带有Intent的OnItemClickListener来打开容器和片段：
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：点击列表中的任何项目时，都会使用声明的持续片段 - 而不是在相应的点击项目上声明的片段。
我试试：
CustomClass customClass = list.get(position);
和
Intent openFragment = new Intent(Hoteis.this, Container.class);
startActivity(openFragment);
但不起作用。
有谁知道怎么做＆＃34; OnItemClick＆＃34;认识到这个位置？
