Android Studio：E/UncaughtException：java.lang.OutOfMemoryError

约斯特·赫塞尔伯思

我一直在寻找解决我的问题的方法。最常见的建议是将 android:hardwareAccelerated="false" 和 android:largeHeap="true" 添加到清单中的应用程序标记，但是我仍然收到以下错误：

我真的很感激任何帮助！

精英

我的建议是修改您的代码以Bitmap从ImageItem类中删除实例，如下所示

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

}

在GridViewAdapter类中从资源 id 加载图像，如下所示

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

}

修改getData你的方法MainActivity.java

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;
}

最后一个在应用程序中添加编译依赖项，build.gradle如下所示

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

并做了。
