Populate Android Spinner Dynamically

I have created a Text View in android like the code below: LinearLayout ll = new LinearLayout(this); ll.setOrientation(LinearLayout.VERTICAL); sv.addView(ll); txt

Solution 1:

You can store the values in a String array then use that array to populate your spinner.

Like this String[] value = new String[]{ "one","two","three".....};

Try this too ArrayList<String> list=new ArrayList<String>();

list.add(your_value);

then String[] value=list.toArray();

Solution 2:

You need to create an impementation of SpinnerAdapter or BaseAdapter and set it as the adapter of the Spinner.

http://developer.android.com/reference/android/widget/SpinnerAdapter.html

You return the views through the adapter from the array.

Also please consider renaming your variables. They aren't very descriptive and naming a variable 11 is poor practice.

Solution 3:

HashMap<String, String> map = newHashMap<>();

map.put("token", prefrences.getUserData().getToken());
map.put("u_id", prefrences.getUserData().getId());

CaregoryID.add("0");
Category.add("Select Category");

appDialogs.showProgressDialog();

callAPiActivity.doPost((Activity) mContext, map, "URL NAME", newGetApiResult() {
    @OverridepublicvoidonSuccesResult(JSONObject result) throws JSONException {
        appDialogs.hideProgressDialog();
        JSONArray countryArray = result.getJSONArray("data");

        for (int i = 0; i < countryArray.length(); i++) {
            JSONObject countryObj = countryArray.getJSONObject(i);
            CaregoryID.add(countryObj.getString("c_id"));
            Category.add(countryObj.getString("c_title_price"));
        }

        categoryAdapter = newArrayAdapter(mContext, R.layout.simple_spinner_item, Category);

        categoryAdapter.setDropDownViewResource( android.R.layout.simple_list_item_1);
        spinnerCategory.setAdapter(categoryAdapter);

    }
}
