In SomeActivity i wrote code like this
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//LayoutInflater inflater = (LayoutInflater) getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
String poName = ((TextView)view.findViewById(R.id.rowPOName)).getText().toString();
// View layout = inflater.inflate(R.layout.detailspopup, null);
initiatePopupWindow(poName);
}
});
private void initiatePopupWindow(String name) {
try {
Cursor cursor2 = null;
LayoutInflater inflater = (LayoutInflater) SomeSample.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.detailspopup, null);
String[] selectedArgs = {name};
try {
cursor2 = db.rawQuery("my query to get employee details", selectedArgs);
if (cursor2.moveToFirst()) {
String firstname = cursor2.getString(cursor2.getColumnIndex("firstname"));
String lastname = cursor2.getString(cursor2.getColumnIndex("lastname"));
String email = cursor2.getString(cursor2.getColumnIndex("email"));
String phone = cursor2.getString(cursor2.getColumnIndex("phone"));
TextView fNname = layout.findViewById(R.id.firstName);
TextView lName = layout.findViewById(R.id.lastName);
TextView emailAdd = layout.findViewById(R.id.emailAdress);
TextView phoneNumber = layout.findViewById(R.id.phoneNumber);
fNname.setText(firstname);
lName.setText(lastname);
emailAdd.setText(email);
phoneNumber.setText(phone);
}
} catch (Exception e) {
Log.d(TAG, e.getMessage());
} finally {
if (cursor2 != null && !cursor2.isClosed()) {
cursor2.close();
}
}
popupWindow = new PopupWindow(layout, 370, 450, true);
popupWindow.showAtLocation(layout, Gravity.CENTER, 0, 0);
} catch (Exception e) {
e.printStackTrace();
}
}
After executing code I got popup window without my employee details populated i.e TextViews are not displaying employee data. It displays only default texts i.e TextView.
need help to solve this
