"mobile_number": "123456789",
"address": "streetno3",
"landmark": "landmarksss",
},
"3": {
"name": "ghi",
"mobile_number": "23423423234",
"address": "abcdefgh",
"landmark": "usa",
},
"4": {
"name": "vvb",
"mobile_number": "55666655",
"address": "xvgghg",
"landmark": "fghgh",
},
"5": {

It is better to make POJO class for this type of data, so that data can be managed easily. But if you have not taken POJO class then now you can take the spinner data from its position and split it to print in EditText.
Suppose if you get data in data string on ItemSelected in spinner you can follow the below code and print it in the edittext.
String split[]=data.split(",");
String name=split[0];
String mobile=split[1];

you have two option
1.Create the custom spinner adapter like below example
CustomAdapter.java

if(position==0){
// Default selected Spinner item
label.setText("Please select company");

}
else
{

label.setText(tempValues.getCompanyName());

Create a bean type arraylist and store all detail in same order in which you are storing inside arrallstates and in onItemSelected method of spinner you always get the position and in both array list you have same position of data so now fetch data from bean type array list and then set it as you want

Use Following code to get ArrayList of colors
ArrayList<String> colorsList = new ArrayList<>();
JsonArray jarr = new JsonArray(result);
for(int i=0;i<jarr.length;i++)
{
JsonArray color = jarr.get("colors");
String myColor="";
for(int k=0;k<color.length;k++){
myColor = color.getString(k)+",";
}
colorsList.add(myColor);
}
From this code you can get ArrayList with each object contains comma seperated colors as String.
Fill Your list adapter with this list and in your list get each color and split it by comma and use it as your background color.

Inside the adapter-> getview method inflate your view and set the following code
view.setBackgroundColor(yourColorCode);
you can take your color code from the parsed json.
EDIT:
In the getView method
getView(parameters)
{
your_current_object=objectList.get(position);
color_arraylist=your_current_object.colorsList;
if(color_arraylist.get(0)!=null)
textview1.setBackgroundColor(color_arraylist.get(0));
if(color_arraylist.get(1)!=null)
textview2.setBackgroundColor(color_arraylist.get(1));
//....so on..
}
And do appropriate type casting if color_arraylist.get(position) cant be directly passed as a parameter to setBackgroundColor(). But i hope it will work without any typecasting.

You can set listview' row color as per your JSON response below :
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.product_listing_items, null);
holder.propic = (ImageView) convertView.findViewById(R.id.productlist_img);
holder.txtproname = (TextView) convertView.findViewById(R.id.productlist_name);
holder.txtprice = (TextView) convertView.findViewById(R.id.productlist_price);
// holder.txtpr = (TextView) convertView.findViewById(R.id.productlist_name);
convertView.setTag(holder);
}else{
**Add you code here for color.**
view.setBackgroundColor(listData.get(position).get(INTEREST_ACCEPT_COLOR));
holder = (ViewHolder) convertView.getTag();
}
holder.txtproname.setText(listData.get(position).get(TAG_NAME));
holder.txtprice.setText(listData.get(position).get(TAG_PRICE));
aQuery.id(holder.propic).image(listData.get(position).get(TAG_IMAGE),true,true,0,R.drawable.meracaslogo);
// image parameter : 1 : memory cache,2:file cache,3:target width,4:fallback image
return convertView;
}
EDIT :
For showing colors to your TextView , you should first put all the colors in Hashmap and pass that hashmap to your adapter.
Now on the basis of keys you can set colors to your Textview.
HashMap<String, String> hashmap;
Method for passing Hashmap in ArrayList.
public ArrayList<HashMap<String, String>> getAllColor(String firstcolor , String second color , String thirdcolor)
{
ArrayList<HashMap<String, String>> array_list = new ArrayList<HashMap<String, String>>();
hashmap = new HashMap<String, String>();
hashmap.put("firstcolor", firstcolor);
hashmap.put("second color",secondcolor);
hashmap.put("thirdcolor",thirdcolor);
array_list.add(hashmap);
}
return array_list;
}
Now Call this method for passing your colors. And pass your Arraylist to your ADAPTER .. And In getView() method you can retrieve it by keys like below :
**ArrayList<HashMap<String, String>> arrayList;** // declare globally
arrayList = "Your adapterList"; // declare in adapter's constructor
in getView() :
if (arrayList.size() != 0)
{
for (int i = 0; i < arrayList.size(); i++)
{
textView1.setBackgroundColor(arrayList.get(i).get("firstcolor"));
textView2.setBackgroundColor(arrayList.get(i).get("secondcolor"));
textView3.setBackgroundColor(arrayList.get(i).get("thirdcolor"));
}
}
Hope this time it will solve your problem.

Show external Image using async task

i want to call an external picture and show it in a listview.
My code works for one second and crashes giving null pointer error. The code logic is like this
1.I have called First async task to fetch Json objects from outside.
Then created a custom adapter to set that objects in custom layout.
2.second async task gets one of the object(which contains the url for the image) and returns Bitmap image.
Could you identify what i did wrong ?

I can suppose the following problem: you have 2 different custom layout:
R.layout.list_item_header
R.layout.list_item
And, according to your code, you are calling for both of them:
new DownloadImageTask((ImageView) convertView.findViewById(R.id.img)).execute(my_url);
If the ImageView R.id.img is NOT in both these layouts, your app will crash. If I'm right, you just need to fix your if/else and invoke the DownloadImageTask only when needed.

Eroor: Attempt to invoke virtual method 'void android.widget.ImageView.setImageBitmap(android.graphics.Bitmap)' on a null object reference clearly says that the ImageView parameter that you are passing in the constructor is NULL.
You are initializing this graphical unit at the runtime. Why not initialize it in the beginning like
Variable_name = (ImageView) convertView.findViewById(R.id.img)
in the OnCreateView..
and pass the created object where you are currently using it. This might solve your error.

Some Tweak in the condition - and works. It was conflict in which view i wanted to set.
if(getListPos == count) {
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.list_item_header,null);
TextView HeaderText = (TextView) convertView.findViewById(R.id.headertext);
TextView HeaderContent = (TextView) convertView.findViewById(R.id.headercontent);
HeaderText.setText(objects.get(position).get(POST_TITLE).toUpperCase());
HeaderContent.setText(objects.get(position).get(POST_CONTENT));
new DownloadImageTask((ImageView) convertView.findViewById(R.id.img)).execute(my_url);
}

Store the hashMap in the view tag.
Button Add = (Button) itemView.findViewById(R.id.add);
Add.setTag(resultp);
Then access it inside onClick() like this
instead of trying to access it by position which may not refer to the current view, access it by its tag. In your code, replace the line
resultp = data.get(position);
with
resultp = (HashMap<String, String>) view.getTag();
EDIT: After adding resultp = data.get(position); as shown above
Replace your onClick() with the following
#Override
public void onClick(View arg0) {
resultp = (HashMap<String, String>) view.getTag();
Intent intent = new Intent(context, SingleItemView.class);
intent.putExtra("title", resultp.get(MainActivity.TITLE));
intent.putExtra("population",resultp.get(MainActivity.POPULATION));
intent.putExtra("thumb_url", resultp.get(MainActivity.THUMB_URL));
context.startActivity(intent);

I will post the answer here for others..
When working with ListView, make sure you set a fixed height to the ListView, otherwise getView() will be called multiple times. This is because the ListView tries to calculate how many items can be visible..

and I believe I have solved the problem.
the BaseAdapter adapter requires that the listview has a high associated set to fill_parent or match_parent
