为什么这个 putExtra 传递的是 String 而不是 int?

Why is this putExtra passing a String instead of an int?

我想通过 intent 将一个 R.drawable id 传递给另一个 activity。我正在使用一个开关来找到正确的可绘制对象,然后使用 putExtra() 来传递它。但是当我调用 getIntExtra 时,它说我传递了一个字符串。这段代码有问题还是在其他地方?

int i = getExerciseId(((TextView)getView().findViewById(R.id.fragTextView)).getText().toString());
            Intent intent = new Intent(v.getContext(), LevelActivity.class);
            intent.putExtra("exerciseId", ((TextView)getView().findViewById(R.id.fragTextView)).getText().toString());
            intent.putExtra("image", i);
            startActivity(intent);
        }

        public int getExerciseId(String s) {
            int i = -1;
            switch (s) {
                case "Weather":
                    i = R.drawable.weather;
                break;
                case "Weekend":
                    i = R.drawable.weekend;
                break;
                case "Hobbies":
                    i = R.drawable.hobbies;
                break;
                case "Music":
                    i = R.drawable.music;
                break;
                case "Family":
                    i = R.drawable.family;
            }
            return i;

编辑:没有日志错误,我在代码中收到一条红线消息:

getIntExtra(String, int) in Intent cannot be applied to (String)

在这行代码中:

intent.getIntExtra("image");

获取整数值

 //wirte name=imge and defaultValue =-1
 //and have a check if value for image is -1 then no value was received

 intent.getIntExtra(name, defaultValue);
getIntExtra(String name, int defaultValue)

您必须为方法调用提供默认值。如果找不到该键,则返回默认值。

http://developer.android.com/reference/android/content/Intent.html#getIntExtra(java.lang.String,%20int)

不是告诉你得到的是字符串,而是你调用的getIntExtra方法参数不足。用

调用它
getIntExtra("image", 0); // or whichever default value you want to use.
