I have an obstacle by changing the data string into a jsonobject, is his org.json.JSONException script error: Value
This coding I am trying
btnLogin.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String username = inputUser.getText().toString().trim();
String password = inputPassword.getText().toString().trim();
// Check for empty data in the form
if (username.trim().length() > 0 && password.trim().length() > 0) {
Map<String,String> params = new HashMap<>();
params.put("username", inputUser.getText().toString());
params.put("password", inputPassword.getText().toString());
sendPostRequest(params);
} else {
// Prompt user to enter credentials
Toast.makeText(getApplicationContext(),
"Silahkan Masukan Username dan Password!", Toast.LENGTH_LONG)
.show();
}
}
});
public void sendPostRequest(Map<String, String> params) {
showDialog();
RequestQueue queue = Volley.newRequestQueue(this);
String url = "http://www.chris-chris.webege.com/login.php";
mCustomRequest = new CustomRequest(Request.Method.POST,
url, params, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Intent intent = new Intent(Login.this,
Coba.class);
startActivity(intent);
finish();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.d("Error", error.getMessage());
hidepDialog();
Toast.makeText(Login.this, "Belum Terhubung Internet! ", Toast.LENGTH_SHORT).show();
}
});
mCustomRequest.setRetryPolicy(new DefaultRetryPolicy(Template.VolleyRetryPolicy.SOCKET_TIMEOUT,
Template.VolleyRetryPolicy.RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
queue.add(mCustomRequest);
}
There are two conditions to convert a string to JSONObject :
1 . The string should be in proper Json format .
2 . Put code in try catch block .
Example:
String jsonString = "{"status":"1","message":"Login successfully","data":{"uid":"1","email":"baleshwar@gmail.com","password":"202cb962ac59075b964b07152d234b70","name":"","role":"1","gender":"","address":"","image":"","is_active":"0","last_login":"0000-00-00 00:00:00","device_id":"0","created_at":"2015-06-03 06:01:02","updated_at":"2015-06-03 11:01:02","location":"","dob":"0000-00-00","descriptions":""}}"
Now convert this string to JSONObject
try{
JSONObject jsonResponse = new JSONObject(result);
}catch(Exception e){
e.printStackTrace();
}
Try this,
If you call your service and try to paste that code inside your isSucsess part
JSONObject jObject = jsonObject.getJSONObject("jsonobjectname");
tvTitle.setText(jObject.getString("your string name"));
