片段上的自定义ListView

Question

I'm trying to get my custom listview on a fragment, but I can only accomplish it through an activity.

here's my code:

MyActivity:   

package com.teampainite.testreviews;

import android.app.Activity; 
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.RatingBar;
import android.widget.TextView;

import java.util.ArrayList;
import java.util.List;


public class MyActivity extends Activity {
private List<ReviewAdapter> Review = new ArrayList<ReviewAdapter>();


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

    populateReviews();
    populateReviewList();
}

private void populateReviewList() {
    Review.add(new ReviewAdapter("Okay", 4, "Levi", "This is an example"));
}

private void populateReviews() {
    ArrayAdapter<ReviewAdapter> adapter = new ReviewList();
    ListView list = (ListView) findViewById(R.id.list);
    list.setFastScrollEnabled(true);
    list.setAdapter(adapter);
}

private class ReviewList extends ArrayAdapter<ReviewAdapter> {
    public ReviewList() {
        super(MyActivity.this, R.layout.review_layout, Review);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View ReviewView = convertView;
        if(ReviewView == null){
            ReviewView = getLayoutInflater().inflate(R.layout.review_layout, parent, false);
        }

        //Find view
        ReviewAdapter currentReview = Review.get(position);

        TextView title = (TextView)ReviewView.findViewById(R.id.review_list_title);
        RatingBar rating = (RatingBar)ReviewView.findViewById(R.id.review_rating);
        TextView user = (TextView)ReviewView.findViewById(R.id.review_user);
        TextView review = (TextView)ReviewView.findViewById(R.id.review_content);

        title.setText(currentReview.getTitle());
        rating.setRating(currentReview.getRating());
        user.setText(currentReview.getUser());
        review.setText(currentReview.getReview());

        rating.setEnabled(false);

        return ReviewView;
    }


}
}

ReviewAdapter:

package com.teampainite.testreviews;

public class ReviewAdapter {
private String Title;
private float Rating;
private String User;
private String Review;


public ReviewAdapter(String Title, float Rating, String User, String Review){
    super();
    this.Title = Title;
    this.Rating = Rating;
    this.User = User;
    this.Review = Review;
}

public String getTitle(){

    return Title;
}

public float getRating(){

    return Rating;
}

public String getUser(){

    return User;
}

public String getReview(){
    return Review;
}

}

Can someone help me put this on a fragment? I want to use an xml based listview, because there are other elements on the main fragment. No other question has addressed this, that I've been able to find.

Fragment code:

package com.teampainite;


import android.app.Fragment;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.RatingBar;
import android.widget.TextView;

import com.teampainite.adapter.ReviewAdapter;

import java.util.ArrayList;
import java.util.List;

public class RestarauntFragment extends Fragment {
private List<ReviewAdapter> Review = new ArrayList<ReviewAdapter>();


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

LayoutInflater inflater;


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    setHasOptionsMenu(true);// Inflate the layout for this fragment

    return inflater.inflate(R.layout.fragment_restaraunt, container, false);
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    ArrayAdapter<ReviewAdapter> adapter = new ArrayAdapter(getActivity(), R.layout.review_list_item, Review);
    ListView list = (ListView)view.findViewById(R.id.reviews_list);
    list.setAdapter(adapter);

    final ImageView favorite = (ImageView) view.findViewById(R.id.favorite);
    favorite.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View view) {
            favorite.setImageDrawable(getActivity().getResources().getDrawable(R.drawable.ic_action_favorite_full));
        }
    });
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.restaraunt, menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            showStoreListings();
            break;
        case R.id.show_menu:
            showMenu();
            break;
    }
    return super.onOptionsItemSelected(item);
}

private void showStoreListings() {
    FragmentTransaction transaction = getFragmentManager().beginTransaction();
    transaction.hide(RestarauntFragment.this);
    transaction.replace(android.R.id.widget_frame, new HomeFragment()).commit();
}

private void showMenu() {
    FragmentTransaction transaction = getFragmentManager().beginTransaction();
    transaction.hide(RestarauntFragment.this);
    transaction.replace(android.R.id.widget_frame, new MenuFragment()).commit();
}


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
    getActivity().setTitle("Applebees");
    populateReviewList();
}

private void populateReviewList() {
    Review.add(new ReviewAdapter("Okay", 1, "Levi", "This is an example")
 }

private class ReviewList extends ArrayAdapter<ReviewAdapter> {
    public ReviewList() {
        super(getActivity(), R.layout.review_list_item, Review);
    }
    public View getView(LayoutInflater inflater, int position, View convertView, ViewGroup parent) {
        View ReviewView = convertView;
        if (ReviewView == null) {
            ReviewView = inflater.inflate(R.layout.review_list_item, parent, false);
        }

        //Find view
        ReviewAdapter currentReview = Review.get(position);

        TextView title = (TextView) ReviewView.findViewById(R.id.review_list_title);
        RatingBar rating = (RatingBar) ReviewView.findViewById(R.id.review_rating);
        TextView user = (TextView) ReviewView.findViewById(R.id.review_user);
        TextView review = (TextView) ReviewView.findViewById(R.id.review_content);

        title.setText(currentReview.getTitle());
        rating.setRating(currentReview.getRating());
        user.setText(currentReview.getUser());
        review.setText(currentReview.getReview());

        rating.setEnabled(false);

        return ReviewView;
    }
} 
}

There are no error, but when I launch I get this:

Answer 1

No other question has addressed this, that I've been able to find.

Please check this Android ListView in fragment example and Create listview in fragment android example.

There are lots of examples if you write "fragment with list views" on Google

Check this: https://www.google.co.in/?gfe_rd=cr&ei=uU0BVJzYIsHN8geZ8IBI&gws_rd=ssl#q=fragment+with+list+views

Answer 2

从logcat可以清楚地看出您在Adapter的getView（）方法（即ReviewList）中犯了错误，您在getView中提到了3 TextView ...正确检查布局文件，其中一个视图必须是RelativeLayout ...这就是为什么你正在得到ClassCastException
