Don't worry. I have make a most of better solution for you. You can see this simple app link below.
private EditText mPasswordField;
public int textLength = 0;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mPasswordField = (EditText) findViewById(R.id.password_field);
mPasswordField.addTextChangedListener(this);
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
String text = mPasswordField.getText().toString();
textLength = mPasswordField.getText().length();
if (text.endsWith("-") || text.endsWith(" ") || text.endsWith(" "))
return;
if (textLength == 1) {
if (!text.contains("(")) {
mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, "(").toString());
mPasswordField.setSelection(mPasswordField.getText().length());
}
} else if (textLength == 5) {
if (!text.contains(")")) {
mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, ")").toString());
mPasswordField.setSelection(mPasswordField.getText().length());
}
} else if (textLength == 6) {
mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, " ").toString());
mPasswordField.setSelection(mPasswordField.getText().length());
} else if (textLength == 10) {
if (!text.contains("-")) {
mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
mPasswordField.setSelection(mPasswordField.getText().length());
}
} else if (textLength == 15) {
if (text.contains("-")) {
mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
mPasswordField.setSelection(mPasswordField.getText().length());
}
}else if (textLength == 18) {
if (text.contains("-")) {
mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
mPasswordField.setSelection(mPasswordField.getText().length());
}
} else if (textLength == 20) {
Intent i = new Intent(MainActivity.this, Activity2.class);
startActivity(i);
}
}
@Override
public void afterTextChanged(Editable s) {
}
Not: Don't forget "implement TextWatcher" with your activity class.
