方法中的getBitMap（Bitmap）类型不适用于参数（byte []）？ [英] Method getBitMap(Bitmap) in the type is not applicable for argument (byte[])?

问题描述

我在某些方面遇到了错误，我不知道如何修复它。

问题是我在循环中出错了一些错误



类型中的方法getBitMap（位图）不适用于参数（byte []）

I got error in some part, i don't know how to fix it.
The problem is i got error some error in looping

"Method getBitMap(Bitmap) in the type is not applicable for argument (byte[])"

if (cursor.moveToFirst()) {
            do {
                Question quest = new Question();
                quest.setID(cursor.getInt(0));
                quest.getBitmap(cursor.getBlob(1)); //error is here
                quest.setQUESTION(cursor.getString(2));
                quest.setANSWER(cursor.getString(3));
                quest.setOPTA(cursor.getString(4));
                quest.setOPTB(cursor.getString(5));
                quest.setOPTC(cursor.getString(6));
                quesList.add(quest);
            } while (cursor.moveToNext());
        }
        // return quest list
        return quesList;

推荐答案

你试图用错误的类型调用方法论点。 cursor.getBlob（1）返回 byte [] （字节数组）而不是位图。

You are trying to call the method with the wrong type of argument. cursor.getBlob(1) returns a byte[] (array of bytes) not a bitmap.
