Customize toast in asyntask in android - android-asynctask

Question

I just wanna ask if it is possible to use my customize toast in onPostExecute of my Asyntask in android. If yes then how? I tried to put it on the onPostExecute but I got a lot red lines. Here is my code for my customize toast:
Typeface tfR= Typeface.createFromAsset(getAssets(), "Gothic_Regular.TTF");
LayoutInflater inflater = getLayoutInflater();
View layouttoast = inflater.inflate(R.layout.toast_bg, (ViewGroup)findViewById(R.id.toastAttribute));
TextView msg = ((TextView) layouttoast.findViewById(R.id.txt_toast));
msg.setTypeface(tfR);
msg.setText(toast_msg);
msg.setTextSize(TypedValue.COMPLEX_UNIT_PX,16);
Toast mytoast = new Toast(getBaseContext());
mytoast.setView(layouttoast);
mytoast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
mytoast.setDuration(Toast.LENGTH_SHORT);
mytoast.show();
Then I want to put it here:
public class DoPost extends AsyncTask<String, Void, Boolean>
{
Exception exception = null;
Context mContext = null;
. . . . .
public DoPost(Context context, String username, String password,
String reportcode, String remarks, String date, String province,
String infotype, String competitor, ArrayList<String> brands,
ArrayList<String> segments)
{
mContext = context;
. . . .
databaseHandler = new DatabaseHandler(context);
if (databaseHandler != null)
{
databaseHandler.close();
databaseHandler.createDB();
}
}
protected void onPreExecute()
{
progressDialog = new ProgressDialog(mContext);
progressDialog.setMessage("Uploading attachment details....");
progressDialog.show();
progressDialog.setCancelable(false);
}
#Override
protected Boolean doInBackground(String... arg0)
{
try {
JSONObject jObject = new JSONObject();
Log.d("DoPost Constants.FILE_URI", Constants.FILE_URI.toString());
Log.d("DoPost create SELECTEDFILE URI", SelectedFiles.listFileUri.toString());
Log.d("DoPost create SELECTEDFILE FILENAME", SelectedFiles.listFileName.toString());
// String filename = "Chapt-19.pdf";
String filename = "";
try {
JSONArray jArraySubrands = new JSONArray();
JSONArray jArrayConsumerSegments = new JSONArray();
JSONArray jArrayReportUpload = new JSONArray();
for (int i = 0; i < Constants.SHARED_PREFERENCES_SUBBRANDS.size(); i++)
{

brand.put("Id", _brands.get(i));
jArraySubrands.put(brand);
}
for (int j = 0; j < Constants.SHARED_PREFERENCES_SEGMENTS.size(); j++)
{
JSONObject consumerSegments = new JSONObject();
consumerSegments.put("Id", _segments.get(j));
jArrayConsumerSegments.put(consumerSegments);
}
for (int i = 0; i < Constants.ARRAYLIST_FILENAME.size(); i++)

I think I've found out what's going on. Your scope is wrong. currently your code is running in AsyncTask, not Activity! That's why you cannot use getAssets, getLayoutInflater, findViewById, getBaseContext. Create your AsyncTask in your xxxActivity. And use Your xxxActivity.this.findViewById, and so on.
