How to create a layout dynamically using Json in android and get value from it ? Here is the Json

Question

{
  layout:[
   {
    tag :"edittext",
    name :"Name",
    hint :"Type your name here"
   },
   {
    tag :"checkbox",
    name :"Is married",
    hint :""

Now the above jsonarray has three jsonobject . it might be any number(4/5/6 any number of jsonobject) . Can any one plz suggest me how to solve this issue ? Thanks

How do you define the position of each view if u want it dynamically. In other case, I believe it is straight forward to create the views by loop parsing the json array and create views to the parent. It is a matter of parsing tag and create respective view with new constructor.Attach the same to the view — rafa

Its better to divide your question in small small parts, so here is something i have for your

Parse JSON and fetch its value : I suggest you to follow How to parse JSON in Android this link and you will have everything from your json.

Check whether control is EditText or Button or anything else : I will suggest you to use switch case for better coding structure

switch (tag ){
    case "edittext":
        //add edittext
        break;
    case "button":
        //add button
        break;
}

follow this links to add controls dynamically

You can create your layout according to the size of jsonarray.

JSONArray jArray = jObject.getJSONArray("layout");
    layout = (LinearLayout) findViewById(R.id.statsviewlayout);

    for (int i=0; i < jArray.length(); i++)
    {
        try {
            JSONObject oneObject = jArray.getJSONObject(i);
            // Pulling items from the array
            String tag = oneObject.getString("tag");
            String name= oneObject.getString("name");
            String hint= oneObject.getString("hint");
            Button button = new Button(this);
            button.setText(name);
            button.setLayoutParams(new LayoutParams(
            ViewGroup.LayoutParams.WRAP_CONTENT,
                ViewGroup.LayoutParams.WRAP_CONTENT));
        layout.addView(buyButton);

        } catch (JSONException e) {
            // Oops
        }
    }
