This article gives an example of how Android programming resolves data in Json format. To share for your reference, the details are as follows:
package com.practice.json;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class JsonDemo extends Activity {
/*
* parsing JSON Example, str Save the JSON Code after parsing the data in LogCat In the output
*/
String TAG = "Json message";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
detectJSON();
}
private void detectJSON() {
String str = "{"+
"\" The date of \" : \"2011-06-06\","+
//Like is JSONObject
"\"Like\" : {"+
"\"Name\" : \" Kevin garnett \","+
"\"Height\" : \"2.11cm\","+
"\"Age\" : 35"+
"},"+
//LikeList is 1 a JSONObject
"\"LikeList\":" +
"{\"List\": " +
"["+
// Here is also JSONObject
"{"+
"\"Name\" : \"Rose\","+
"\"Height\" : \"190cm\","+
"\"Age\" : 23"+
"},"+
// Here is also JSONObject
"{"+
"\"Name\" : \" Kobe Bryant \","+
"\"Height\" : \"198cm\","+
"\"Age\" : 33"+
"}"+
"]"+
"}"+
"}";
try {
JSONObject dataJson = new JSONObject(str);
Log.d(TAG, dataJson.getString(" The date of "));
JSONObject nbaJson = dataJson.getJSONObject("Like");
Log.d(TAG, nbaJson.getString("Name"));
Log.d(TAG, nbaJson.getString("Height"));
Log.d(TAG, nbaJson.get("Age").toString());
JSONObject listJson = dataJson.getJSONObject("LikeList");
JSONArray arrayJson = listJson.getJSONArray("List");
for(int i=0;i<arrayJson.length();i++) {
JSONObject tempJson = arrayJson.optJSONObject(i);
Log.d(TAG, tempJson.getString("Name"));
Log.d(TAG, tempJson.getString("Height"));
Log.d(TAG, tempJson.getString("Age").toString());
}
} catch (JSONException e) {
System.out.println("Something wrong...");
e.printStackTrace();
}
}
}
I hope this article has been helpful in Android programming.
