Androidスタジオ：E/UncaughtException：java.lang.OutOfMemoryError

Question

私は私の問題の解決策を探していました。最も一般的な推奨事項はアンドロイドを追加するには、次のとおりです。hardwareAccelerated =「false」にし、アンドロイド：

私はこれで任意の助けを本当に感謝！

Answer 1

私の提案は、あなたのMainActivity.javaのgetData方法を変更し

public class GridViewAdapter extends ArrayAdapter<ImageItem> { 

    // your old logic here 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     // your old logic here 

     // holder.image.setImageBitmap(item.getImage()); 
     Picasso.with(context).load(item.getImageResource()).into(holder.image); 
    } 

    // your old logic here 

} 

以下のようなリソースIDからGridViewAdapterクラスのロードイメージで

public class ImageItem { 

    private int arrayIndex; 
    private int imageResource; 
    private String title; 

    public ImageItem(int arrayIndex, int imageResource, String title) { 
     super(); 
     this.arrayIndex = arrayIndex; 
     this.imageResource = imageResource; 
     this.title = title; 
    } 

    public int getImageResource() { 
     return imageResource; 
    } 

    public void setImageResource(int imageResource) { 
     this.imageResource = imageResource; 
    } 

    // rest methods should be same 

} 

以下のようにImageItemクラスからBitmapインスタンスを削除するようにコードを変更することです

private ArrayList<ImageItem> getData() { 
    final ArrayList<ImageItem> imageItems = new ArrayList<>(); 
    TypedArray imgs = getResources().obtainTypedArray(R.array.image_ids); 
    for (int i = 0; i < imgs.length(); i++) { 
     Log.d(TAG, "Image ID: " + String.valueOf(i)); 
     // no need to load image here 
     // Bitmap bitmap = BitmapFactory.decodeResource(getResources(), imgs.getResourceId(i, -1)); 
     imageItems.add(new ImageItem(i, imgs.getResourceId(i, -1), "Image#" + i)); 
    } 
    return imageItems; 
} 

アプリのbuild.gradle

dependencies { 
    ... 
    compile 'com.squareup.picasso:picasso:2.5.0' 
    ... 
} 

と行われ、以下のようにコンパイル依存関係を追加する最後の1。
