I have a problem with string comparison. For example, there is this string:

\"hello world i am from heaven\"

I want to search if this strin

Answer 1

I got the solution finally.

public void onTextChanged(CharSequence s, int start, int before, int count) {

                        ArrayList> arrayTemplist = new ArrayList>();
                        String searchString = mEditText.getText().toString();
                        if(searchString.equals("")){new DownloadJSON().execute();}

                    else{


                    for (int i = 0; i < arraylist.size(); i++) {
                        String currentString = arraylist.get(i).get(MainActivity.COUNTRY);
                        if (searchString.toLowerCase().contains(currentString.toLowerCase())) {
    //pass the character-sequence instead of currentstring

                            arrayTemplist.add(arraylist.get(i));
                        }
                    }
                        }
                        adapter = new ListViewAdapter(MainActivity.this, arrayTemplist);
                        listview.setAdapter(adapter);

                }


            });
    }

Replace the above code with this one:

public void onTextChanged(CharSequence s, int start, int before, int count) {

                        ArrayList> arrayTemplist = new ArrayList>();
                        String searchString = mEditText.getText().toString();
                        if(searchString.equals("")){new DownloadJSON().execute();}

                    else{


                    for (int i = 0; i < arraylist.size(); i++) {
                        String currentString = arraylist.get(i).get(MainActivity.COUNTRY);
                        if (currentString.toLowerCase().contains(searchString.toLowerCase())) {
    //pass the character-sequence instead of currentstring

                            arrayTemplist.add(arraylist.get(i));
                        }
                    }
                        }
                        adapter = new ListViewAdapter(MainActivity.this, arrayTemplist);
                        listview.setAdapter(adapter);

                }


            });
