首先在这里检查了这个，我没有找到适合我的解决方案。 现在，所以我启动了我的应用程序，然后按下strat按钮，当它应该移动到另一个activirty它抛出这个错误。 日志

@Override

Random r = new Random();//הדגל שיבחר לשאלה
int num = r.nextInt(70);//Up

// final Flags d = f; // trying to make it final but it dosent help
//fn = f.getName().toString();
pic = f.getImage().toString();
pic_view(pic);//מעבר לפונקציה להשמת התמונה של הדגל במשחק
//מערך ארבע כפתורים כנגד ארבע תשובות
Button [] b = new Button[4];

Answers.add(db.getFlag(num).getName().toString());
Collections.shuffle(Answers);//ערבוב התשובות
for(int i=0;i<Answers.size();i++)

ImageView imageView = (ImageView)findViewById(R.id.imageView1);
String uri ="@drawable/";
uri += pic2;
int imageResource = getResources().getIdentifier(uri, pic2, getPackageName());//הצוות התמונה
Drawable res= getResources().getDrawable(imageResource);//ציור התמונה

}
}
答案 0 :(得分：0)
请尝试更改pic_view(...)中的以下行
int imageResource = getResources().getIdentifier(uri, pic2, getPackageName());
到
int imageResource = getResources().getIdentifier(pic2, "drawable", getPackageName());
