Set ToggleButton status from incoming JSON data

Question

I am trying to follow an Android tutorial to modify a MySQL database data from Android app. I am fairly new to the concept of JSON parsing and I am stuck at setting the values of toggles in my app's list-view according to the 'status' values received from database through JSON. In my database, I have a field named 'status' in table 'devices', and a ToggleButton is associated with each row received through JSON. I want to use the retrieved values (0 or 1) to set my associated toggle in the app to ON if the value is 1 and to OFF if the retrieved value is 0. But I don't know how I can achieve that.

Here's the doInBackground function from the activity that shows my list-view:

protected String doInBackground(String... args) {
        // Building Parameters
        List<NameValuePair> params = new ArrayList<NameValuePair>();
        // getting JSON string from URL
        JSONObject json = jParser.makeHttpRequest(url_all_products, "GET", params);

        // Check your log cat for JSON reponse
        Log.d("All Products: ", json.toString());

        try {
            // Checking for SUCCESS TAG
            int success = json.getInt(TAG_SUCCESS);

            if (success == 1) {
                // products found
                // Getting Array of Products
                products = json.getJSONArray(TAG_PRODUCTS);

                // looping through All Products
                for (int i = 0; i < products.length(); i++) {
                    JSONObject c = products.getJSONObject(i);

                    // Storing each json item in variable
                    String id = c.getString(TAG_PID);
                    String name = c.getString(TAG_NAME);
                    String status = c.getString(TAG_STATUS);

                    // creating new HashMap
                    HashMap<String, String> map = new HashMap<String, String>();

                    // adding each child node to HashMap key => value
                    map.put(TAG_PID, id);
                    map.put(TAG_NAME, name);
                    map.put(TAG_STATUS, status);

                    // adding HashList to ArrayList
                    productsList.add(map);
                }
            } else {
                // no products found
                // Launch Add New product Activity
                Intent i = new Intent(getApplicationContext(),
                        NewDeviceActivity.class);
                // Closing all previous activities
                i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(i);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

        return null;
    }

    /**
     * After completing background task Dismiss the progress dialog
     * **/
    protected void onPostExecute(String file_url) {
        // dismiss the dialog after getting all products
        pDialog.dismiss();
        // updating UI from Background Thread
        runOnUiThread(new Runnable() {
            public void run() {
                /**
                 * Updating parsed JSON data into ListView
                 * */
                ListAdapter adapter = new SimpleAdapter(
                        AllDevicesActivity.this, productsList,
                        R.layout.list_item, new String[] { TAG_PID,
                                TAG_NAME, TAG_STATUS},
                        new int[] { R.id.pid, R.id.name, R.id.status });
                // updating listview
                setListAdapter(adapter);
            }
        });

    }

The XML file is:

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <!-- Product id (pid) - will be HIDDEN - used to pass to other activity -->
    <TextView
        android:id="@+id/pid"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:visibility="gone" />

    <TextView
        android:id="@+id/status"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:visibility="gone" />

    <TextView
        android:id="@+id/name"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:paddingTop="6dip"
        android:paddingLeft="7dip"
        android:textSize="17dip"
        android:textStyle="bold" />

    <ToggleButton
        android:id="@+id/toggleButton1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_marginRight="7dp"
        android:text="ToggleButton" />

</RelativeLayout>

The values (name, ID and status) are received just fine, I have reached thus far: Screenshot of the app after execution of above code.

But I have no idea how to use the received 'status' value to change toggle associated with every list-view item. I tried to define the ToggleButton in the onCreate method like this:

tb = (ToggleButton) findViewById(R.id.toggleButton1);

And then tried this in the for loop of doInBackground method above:

if (status == "1")
{
     tb.setChecked(true);           
}

But the app crashes if I do that may be because I have not idea where to put the associated code. Any help regarding this is appreciated.

Thank you!

Answer 1

i used editText to retrieve value from JSON then convert it into toggle button

try this in your onPostExecute()

protected void onPostExecute(Void result) {
        try {
            EditText1.setText(json.getString("your_param"));
            EditText1.setVisibility(View.INVISIBLE);


            if (EditText1.getText().toString().equalsIgnoreCase("1")) {

                toggleButton1.setChecked(true);
            } else if (EditText1.getText().toString().equalsIgnoreCase("0")) {

                toggleButton1.setChecked(false);

            }
    }
