从 Drawable imageResource Exception 导入图片
Import image from Drawable imageResource Exception
在 Whosebug 上尝试查找后没有找到我想问一下。
我创建了一个函数，它将从我的 Drawable 文件夹中导入图像并将其显示在 Imageview 上。（我的数据库有 218 张图片，全部按 ID 从 0 开始排序）
代码:(之后我会解释问题）
private void pic_view(String pic2) {
// TODO Auto-generated method stub
//גישה לדגל לפי שמו וייבוא התמונה
Log.d("Result from pic function " , pic2);
ImageView imageView = (ImageView)findViewById(R.id.imageView1);
String uri ="@drawable/";
uri += pic2;
int imageResource = getResources().getIdentifier(uri, pic2, getPackageName());//הצוות התמונה
Log.d("Imageresources", String.valueOf(imageResource));//get 0 problem
//if(imageResources!=0)
Drawable res= getResources().getDrawable(imageResource);//ציור התמונה
imageView.setImageDrawable(res);
}
当 imageResource 变为（归零）零时，我遇到了一个致命异常，我不知道为什么。
我没有找到另一种从 drawable 导入图像的方法。
结论：
为什么imageResource会归零希望你能帮我解决一下
