java - Android 内存不足错误？

Question

我的 Android Activity 有这些代码。但它给了我 java.lang.outofmemoryerror: java.lang.string[] of length 2131492864 ecxeeds the VM limit。我想知道我的代码是否有问题或者我的 String.xml 包含太多项目？还是图片太多？我有大约 120 个 150x150 图像，每个图像大约 20kb。如果可能的话我想知道如何解决这个问题。提前致谢。

public class ChampionInfo extends FragmentActivity {

GridView gridtable;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_champion_info);

    gridtable = (GridView) findViewById(R.id.gridtable);
    gridtable.setAdapter(new GridAdapter(this));
}

public class GridAdapter extends BaseAdapter {
    private Context mContext;

    String[] list = new String[R.array.championlist];

    int[] champImage = getImage();

    public int[] getImage() {
        int[] tempImage = new int[list.length];

        for (int i = 0; i > list.length; i++) {
            tempImage[i] = getResources().getIdentifier(list[i],
                    "drawable", getPackageName());
        }

        return tempImage;

    }

    // Constructor
    public GridAdapter(Context c) {
        mContext = c;
    }

    public int getCount() {
        return champImage.length;
    }

    public Object getItem(int position) {
        return null;
    }

    public long getItemId(int position) {
        return 0;
    }

    // create a new ImageView for each item referenced by the Adapter
    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView;
        if (convertView == null) {
            imageView = new ImageView(mContext);
            imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(8, 8, 8, 8);

        } else {
            imageView = (ImageView) convertView;
        }

        imageView.setImageResource(champImage[position]);
        return imageView;
    }

    // Keep all Images in array

}

}

这些是目录中显示的错误:

Answer 1

这一行没有多大意义:

String[] list = new String[R.array.championlist];

R.array.championlist 是一个整数，指向我假设的字符串数组资源。您可以使用 Resources.getStringArray(int) 加载该字符串数组。 .

String[] list = resources.getStringArray(R.array.championlist);
