کاستومایز کردن EditText

اون کد رو خیلی سریع نوشتم و تست نکرده بودم. این یکی تست شده. البته بجای getText باید از getPlainText استفاده کنید:

public class Digit3EditText extends AppCompatEditText { public Digit3EditText(Context context) { super(context); init(); } public Digit3EditText(Context context, AttributeSet attrs) { super(context, attrs); init(); } public Digit3EditText(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); init(); } private void init() { if (!isInEditMode()) { setText("0 تومان"); setSelection(getText().toString().length()); setOnKeyListener(new OnKeyListener() { @Override public boolean onKey(View view, int keyCode, KeyEvent keyEvent) { if (keyEvent.getAction() == KeyEvent.ACTION_UP) { if (keyCode == KeyEvent.KEYCODE_DEL) { backSpace(); } else { DecimalFormat formatter = new DecimalFormat("#"); formatter.setGroupingUsed(true); formatter.setGroupingSize(3); String s = getText().toString().replaceAll("[^0-9]", ""); switch (keyCode) { case KeyEvent.KEYCODE_0: s += "0"; break; case KeyEvent.KEYCODE_1: s += "1"; break; case KeyEvent.KEYCODE_2: s += "2"; break; case KeyEvent.KEYCODE_3: s += "3"; break; case KeyEvent.KEYCODE_4: s += "4"; break; case KeyEvent.KEYCODE_5: s += "5"; break; case KeyEvent.KEYCODE_6: s += "6"; break; case KeyEvent.KEYCODE_7: s += "7"; break; case KeyEvent.KEYCODE_8: s += "8"; break; case KeyEvent.KEYCODE_9: s += "9"; break; } if (s.length() > 0) { try { s = formatter.format(Long.parseLong(s)) + " تومان"; } catch (NumberFormatException e) { s = formatter.format(Long.parseLong(s.substring(0, s.length() - 1))) + " تومان"; } } else { s = "0 تومان"; } setText(s); setSelection(s.length()); } } return true; } }); addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { if (after == 0) { removeTextChangedListener(this); backSpace(); addTextChangedListener(this); } } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { } @Override public void afterTextChanged(Editable editable) { } }); } } public String getPlainText() { return getText().toString().replaceAll("[^0-9]", ""); } public void backSpace() { DecimalFormat formatter = new DecimalFormat("#"); formatter.setGroupingUsed(true); formatter.setGroupingSize(3); String s = getText().toString().replaceAll("[^0-9]", ""); s = s.length() > 0 ? s.substring(0, s.length() - 1) : "0"; if (s.length() > 0) { try { s = formatter.format(Long.parseLong(s)) + " تومان"; } catch (NumberFormatException e) { s = formatter.format(Long.parseLong(s.substring(0, s.length() - 1))) + " تومان"; } } else { s = "0 تومان"; } setText(s); setSelection(s.length()); }
}
