我在我的应用中使用split()和TextInputLayout以及TextInputEditText，我不允许两个单词之间的空格，所以如果我选择一个空格自动完成的项目下拉或拼写检查，我遇到了android:inputType="textAutoComplete"：
IndexOutOfBoundsException在我的活动中，我使用java.lang.IndexOutOfBoundsException: setSpan (0 ... 8) ends beyond length 7

：
TextWatcher我理解private final TextWatcher mTextWatcher = new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable str) {
//don't allow special characters
if (str.length() > 0) {
StringBuilder validatedHandleBuilder = new StringBuilder();
for (char c : str.toCharArray()) {
if (mProfileManager.isAlphaNumeric(c)) {
validatedHandleBuilder.append(c);
}
}
String validatedHandle = validatedHandleBuilder.toString();
if (!str.equals(validatedHandle)) {
int cursorPosition = mTextInputEditText.getSelectionEnd() - 1;
mTextInputEditText.setText(validatedHandle);
int newCursorPosition = cursorPosition < mTextInputEditText.length() ? cursorPosition : mTextInputEditText.length();
mTextInputEditText.setSelection(newCursorPosition);
}
}
}
};
，但我无法确定我可以处理此异常的代码行。
