私はアンドロイドの初心者ですから、たくさんの画像を表示するアプリを作ろうとしています。問題は、私がアプリケーションを実行し、私がスクロールしているとき、アプリケーションがクラッシュし、エラーjava.lang.OutOfMemoryErrorを表示することです。android java.lang.OutOfMemoryError recyclerviewたくさんの画像を持っています
私はアンドロイドスタジオ、minSdkVersion 15を使用しています。すべての画像は20,30 KBより大きくはありませんが、表示する画像はたくさんあります。すべての画像は引き出しフォルダにあります。
これは私が画像を含むオブジェクトへのすべてのデータを追加したクラスです。これは、アダプタで
package com.example.android.animalsoundsforchildren;
import java.util.ArrayList;
public class Zivotinje {
private String mAnimal_name;
private int mAnimal_slika;
private int mSound;
private String mkey;
public Zivotinje(String animalName, int slika, int sound, String key){
this.setmAnimal_name(animalName);
this.setmAnimal_slika(slika);
this.setmSound(sound);
this.setMkey(key);
}
public String getmAnimal_name() {
return mAnimal_name;
}
public void setmAnimal_name(String mAnimal_name) {
this.mAnimal_name = mAnimal_name;
}
public int getmAnimal_slika() {
return mAnimal_slika;
}
public void setmAnimal_slika(int mAnimal_slika) {
this.mAnimal_slika = mAnimal_slika;
}
public int getmSound() {
return mSound;
}
public void setmSound(int mSound) {
this.mSound = mSound;
}
public String getMkey() {
return mkey;
}
public void setMkey(String mkey) {
this.mkey = mkey;
}

public static ArrayList<Zivotinje> createZivotinjeList(){

zivotinje.add(new Zivotinje("Sheep", R.drawable.domestic_sheep, R.raw.domestic_sheep, "Domestic"));

//Dohvacamo sve zivotinje i sortiramo specificne po kljucu tako da kad kliknemo recimo others pozove se ovo
public static ArrayList<Zivotinje> createZivotinjeListPero(String zivotinjeMenu) {

for (Zivotinje ziv : zivotinje) {
if (ziv.mkey == zivotinjeMenu) {
zivotinjeLista.add(ziv);
}
}
return zivotinjeLista;
}
}、私はonbindviewholder方法で問題を処理する必要がありますが、私は方法がわからないと思います：

public ZivotinjeAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Context context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
// Inflate the custom layout
View contactView = inflater.inflate(R.layout.item_zivotinje, parent, false);
// Return a new holder instance
ViewHolder viewHolder = new ViewHolder(contactView);
return viewHolder;
}
@Override
public void onBindViewHolder(ZivotinjeAdapter.ViewHolder viewHolder, int position) {
Zivotinje zivotinjeIme = mZivotinje.get(position);
// Set item views based on the data model
TextView textView = viewHolder.nameTextView;
textView.setText(zivotinjeIme.getmAnimal_name());
//THIS IS WHERE I HANDALE IMAGE VIEW
ImageView slika_source = viewHolder.imageView;
slika_source.setImageResource(zivotinjeIme.getmAnimal_slika());
viewHolder.setItem(mZivotinje.get(position));
}
@Override
public int getItemCount() {
return mZivotinje.size();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
public ImageView imageView;
public TextView nameTextView;
private Zivotinje mItem;
public void setItem(Zivotinje item) {
this.mItem = item;
}
public ViewHolder(final View itemView) {
super(itemView);
nameTextView = (TextView) itemView.findViewById(R.id.zivotinjaIme_id);
imageView = (ImageView) itemView.findViewById(R.id.slika_id);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
MediaPlayer mediaPlayer = MediaPlayer.create(v.getContext(), mItem.getmSound());
mediaPlayer.start();
}
});
}
}
private List<Zivotinje> mZivotinje;
public ZivotinjeAdapter(List<Zivotinje> animals) {
mZivotinje = animals;
}
}
