我在我的应用程序中使用TextInputLayoutand我不允许两个单词之间有空格所以如果我在自动完成下拉或拼写检查中选择一个带有空格的项目，我会遇到：TextInputEditTextandroid:inputType="textAutoComplete"IndexOutOfBoundsException

java.lang.IndexOutOfBoundsException: setSpan (0 ... 8) ends beyond length 7

            at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:776)

在我的活动中，我使用TextWatcher：

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);
        }
    }
}   
};

我理解，IndexOutOfBoundsException但我无法确定我可以处理此异常的代码行。
