ArrayList > android接受变量(ArrayList> android take variables)

ArrayList > android接受变量(ArrayList> android take variables)

例如，我如何使用标记URL获取所有变量？

这种变量： ArrayList<HashMap<String, String>> ？

How can i take all variables with tag URL for example?

Of this kind of variable: ArrayList<HashMap<String, String>>?

最满意答案

这是hashmap中log all键和值的示例

ArrayList<HashMap<String, String>> arrayList = new ArrayList<HashMap<String,String>>(); HashMap<String, String> h1 = new HashMap<String, String>(); h1.put("h1_key_1", "h1_value_1"); h1.put("h1_key_2", "h1_value_2"); arrayList.add(h1); HashMap<String, String> h2 = new HashMap<String, String>(); h2.put("h2_key_1", "h2_value_1"); h2.put("h2_key_2", "h2_value_2"); arrayList.add(h2); for (HashMap<String, String> hashMap : arrayList) { System.out.println(hashMap.keySet()); for (String key : hashMap.keySet()) { System.out.println(hashMap.get(key)); } }

This is example for log all key and value in hashmap

ArrayList<HashMap<String, String>> arrayList = new ArrayList<HashMap<String,String>>(); HashMap<String, String> h1 = new HashMap<String, String>(); h1.put("h1_key_1", "h1_value_1"); h1.put("h1_key_2", "h1_value_2"); arrayList.add(h1); HashMap<String, String> h2 = new HashMap<String, String>(); h2.put("h2_key_1", "h2_value_1"); h2.put("h2_key_2", "h2_value_2"); arrayList.add(h2); for (HashMap<String, String> hashMap : arrayList) { System.out.println(hashMap.keySet()); for (String key : hashMap.keySet()) { System.out.println(hashMap.get(key)); } }
