TextView not displaying text

Question

I am trying to get text from getText method from database and display the string in the TextView. But I have no idea why it is not working.

Database:

 public String getType(String search){

        String type="";

        String searchTypeQuery="SELECT * FROM "+ DatabaseData.TABLE_NAME + " WHERE "+ DatabaseData.NAME+ " LIKE '%" +search +"%'";
        SQLiteDatabase db=this.getWritableDatabase();

        Cursor cursor=db.rawQuery(searchTypeQuery,null);
        // looping through all rows
        if (cursor.moveToFirst()) {
            do {

                String objectName = cursor.getString(cursor.getColumnIndex(DatabaseData.TYPE));
                type=objectName;

            } while (cursor.moveToNext());
        }

        cursor.close();
        db.close();

        // return the list of records
        return type;
    }

Main:

if (database.getType("Sample")=="A"){
                textview.setText("Type");
            }

I tried this "textview.setText(database.getType("Sample"));" and it worked. But when i try the above code it doesn't work.

Try database.getType("Sample").equals("A") as the if-condition. And here is explanation.

You have to use equals method when you are comparing Strings. Remember that Strings are objects.

You can read this to know more info about comparing Strings: https://docs.oracle.com/javase/tutorial/java/data/comparestrings.html
