小编Sar*_*bat的帖子

可能重复:
Android,从字符串获取资源ID？

String res = "R.drawable.image1";

我需要得到它的INT id.请帮我!

昨天申请工作正常,我没有编辑我的代码.但现在它不起作用.logcat是

public Cursor getImages(long rowId) throws SQLException
    {
        Cursor mCursor =
                db.rawQuery("select * from Pictures WHERE id=" + rowId + ";", null);
        if (mCursor != null) {
            mCursor.moveToFirst();
        }
        return mCursor;


    }

表列"id,pic,comment"

我想将pic和comment的值取为字符串数组.

我的代码是:

int i=0;
        Cursor c1 = db.getImages(memberId);     
        c1.moveToFirst();
        while(c1.isLast()){
            pictures[i]=c1.getString(1);
            comments[i]=c1.getString(2);
            i++;
        }

这不起作用.

img_url = new URL("http://graph.facebook.com/" + user.getId() + "/picture?type=large");
                            InputStream is = img_url.openConnection().getInputStream();
                            Bitmap avatar;
                            avatar = BitmapFactory.decodeStream(is);
                            ivAvatar.setImageBitmap(avatar);

当我得到Facebook个人资料图片时,发生以下错误.

android.os.NetworkOnMainThreadException

怎么解决？
