Insert JSON Object into another JSON Object

See more JSON Examples

Demonstrates how to insert one JSON object into another. Effectively, the JSON object must be copied into the other.. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Imagine we have two separate JSON objects.
    CkJsonObject jsonA = new CkJsonObject();
    jsonA.UpdateString("animal","zebra");
    jsonA.UpdateString("colors[0]","white");
    jsonA.UpdateString("colors[1]","black");

    jsonA.put_EmitCompact(false);
    Log.i(TAG, jsonA.emit());

    // jsonA contains:

    // {
    //   "animal": "zebra",
    //   "colors": [
    //     "white",
    //     "black"
    //   ]
    // }

    CkJsonObject jsonB = new CkJsonObject();
    jsonB.UpdateString("type","mammal");
    jsonB.UpdateBool("carnivore",false);

    jsonB.put_EmitCompact(false);
    Log.i(TAG, jsonB.emit());

    // jsonB contains:

    // {
    //   "type": "mammal",
    //   "carnivore": false
    // }

    // Let's say we want to insert jsonB into jsonA to get this:

    // {
    //   "animal": "zebra",
    //   "info" " {
    //       "type": "mammal",
    //       "carnivore": false
    // 	},
    //   "colors": [
    //     "white",
    //     "black"
    //   ]
    // }

    jsonA.AddObjectCopyAt(1,"info",jsonB);

    Log.i(TAG, jsonA.emit());

    // The result is this:

    // {
    //   "animal": "zebra",
    //   "info": {
    //     "type": "mammal",
    //     "carnivore": false
    //   },
    //   "colors": [
    //     "white",
    //     "black"
    //   ]
    // }
