Android如何在logcat中查看长字符串

Question

I have a HashMap<String, LinkedHashMap<String,String> that is fairly long (not an issue) and I'm trying to make sure things look correct before I use the data inside it. To do this I'm trying to just attempting to do this Log.v("productsFromDB",products.toString()) but in the LogCat It shows about 1/3 of it. Is there a way to output the entire map?

Logcat can only show about 4000 characters. So you need to call a recursive function to see the entire hashmap. Try this function:

public static void longLog(String str) {
    if (str.length() > 4000) {
        Log.d("", str.substring(0, 4000));
        longLog(str.substring(4000));
    } else
        Log.d("", str);
}
