Detailed explanations and examples of Volley in Android development
Recently, when I was working on projects, I have various gets and posts. It's crazy. I don't know anything like this, so I don't know what to do. Then Baidu took a look and found that I can use volley to request and obtain networks. Let's introduce the usage of volley below.
There are three ways to volley:JsonObjectRequest，JsonArrayRequest，StringRequest. In fact, it's almost the same, it's OK to learn from one example and learn from it. Here I will talk about JsonObjectRequest.
The method is as follows:
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(,null,Listener,ErrListener);
Examples are as follows:
RequestQueue myQueue = (getContext());
Map<String, String> params = new HashMap<String, String>();
("dataStr", "2016/3/18");
("selectRow", "0");
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(, url, new JSONObject(params),new <JSONObject>() {
public void onResponse(JSONObject jsonObject) {
try {
(("data").getString("CreateTime"));
(("data").getString("Title"));
} catch (Exception e) {
();
}
}
}, new () {
public void onErrorResponse(VolleyError volleyError) {
("error", volleyError + "");
}
}) ;
("tag");
(jsonObjectRequest);
This will solve it. . I can say that because of this, I have been busy on Friday afternoon until now... Okay, you can try to solve your current problem.
