Recycle-view раздувает разные строки: - Получение исключения при привязке данных

Ответ 1

Причина onCreateViewHolder(ViewGroup parent, int viewType). Параметр - тип вида, но не позиция. Использование int listViewItemType = getItemViewType(viewType) неверно, потому что position следует передать в getItemViewType.

Короче говоря, вы должны использовать viewType напрямую и удалить listViewItemType в onCreateViewHolder.

Ответ 2

@Joshua сократил мою проблему.
Для других пользователей я размещаю здесь код для раздувания разных строк (3 строки) в RecycleView
И он отлично работает, проверьте приведенные ниже строки кода: - Я отправляю свой полный код здесь, пожалуйста, проверьте: -

Здесь RecyleClass.java - мой основной класс

package com.tv.practise.recycleview;

import android.app.Activity;
import android.os.Bundle;
import android.support.v7.widget.DefaultItemAnimator;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

import com.tv.practise.R;

import java.util.ArrayList;

/**

public class RecyleClass extends Activity {

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

        RecyclerView recycler_vw = (RecyclerView)findViewById(R.id.recycler_vw);


        ArrayList<RecycleBen> arrayList = new ArrayList<>();

        for (int i = 0;i<=25;i++)
        {
            RecycleBen bean = new RecycleBen();

            if(i%2==0)
            {

                bean.setType_row("1");
                bean.setName("First element");
                bean.setImage_url("http://www.androhub.com/wp-content/uploads/2015/09/staggeredrecyclerview_banner.jpg");
            }
            else if(i%3==0)
            {
                bean.setType_row("2");
                bean.setName("Second element");
                bean.setImage_url("http://i.stack.imgur.com/snB84.png");
            }
            else
            {
                bean.setType_row("3");
                bean.setName("Third element");
                bean.setImage_url("http://inducesmile.com/wp-content/uploads/2015/05/gridbanner.jpg");
            }

            arrayList.add(bean);

        }

        RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(this);

        recycler_vw.setLayoutManager(mLayoutManager);
        recycler_vw.setItemAnimator(new DefaultItemAnimator());
        recycler_vw.setAdapter(new RecycleDataAdapter(this, arrayList));

    }
}

Вот мой layout для RecyleClass.java, который recycle_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">


    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_vw"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clipToPadding="false"
        />
</LinearLayout>

Лента для RecycleView с CardView и Glide

 // CardView
    compile 'com.android.support:cardview-v7:23.4.0'
    // RecyclerView
    compile 'com.android.support:recyclerview-v7:23.4.0'

    // For the glide libraray
    compile 'com.github.bumptech.glide:glide:3.7.0'

И ниже мой класс getter и setter, который RecycleBen.java

package com.tv.practise.recycleview;

/**
 * Created by Ravindra Kushwaha on 10/10/16.
 */
public class RecycleBen {

    private String type_row;
    private String name;
    private String image_url;


    public String getType_row() {
        return type_row;
    }

    public void setType_row(String type_row) {
        this.type_row = type_row;
    }

    public String getName() {
        return name;
    }

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

    public String getImage_url() {
        return image_url;
    }

    public void setImage_url(String image_url) {
        this.image_url = image_url;
    }
}

И в последнем классе Adapter, который RecycleDataAdapter.java

package com.tv.practise.adapter;

/**
 * Created by Ravindra Kushwaha on 10/10/16.
 */
public class RecycleDataAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private Context mContext;
    private ArrayList<RecycleBen> data;

            this.first_data_tv = (TextView) v.findViewById(R.id.first_data_tv);
        }
    }

    public   class SimpleImage extends  RecyclerView.ViewHolder {
        ImageView second_data_iv;
        ProgressBar second_pb;

        public SimpleImage(View v) {
            super(v);
            this.second_data_iv = (ImageView) v.findViewById(R.id.second_data_iv);
            this.second_pb = (ProgressBar)v.findViewById(R.id.second_pb);
        }
    }

    public  class SimpleImageWithText extends  RecyclerView.ViewHolder {
        TextView third_data_tv;
        ImageView third_iv;
        ProgressBar third_pb;

        public SimpleImageWithText(View v) {
            super(v);
            this.third_data_tv = (TextView) v.findViewById(R.id.third_data_tv);
            this.third_iv = (ImageView) v.findViewById(R.id.third_iv);
            this.third_pb = (ProgressBar)v.findViewById(R.id.third_pb);
        }
    }

    public RecycleDataAdapter(Context mContext, ArrayList<RecycleBen> data) {
        this.mContext = mContext;
        this.data = data;
    }

    @Override

Поскольку мы раздуваем разные строки в RecycleView, поэтому мы использовали здесь 3 макет, которые являются recycle_first_item.xml, recycle_fsecond_item.xml и последний recycle_third_item.xml
Один за другим я показываю весь макет xml, который выглядит следующим образом: -

recycle_first_item.xml
