我想以编程方式在EditText中启用或禁用自动大写,自动更正或密码字段(显示项目符号)。这意味着不是来自XML。
我也想避免使用TextWatcher解决方案,而更多地关注InputFilter或其他解决方案。
将EditText操纵为Editable可以附加InputFilter,但是我无法以编程方式使它们工作。另外,诸如setAllCaps之类的EditText方法对我实际上没有任何作用。自动校正也是如此。这是我尝试的自动更正(以向您显示我所在的位置以及一些思考过程):
/** SpellCheck filter for auto-correcting words. */
class SpellCheckFilter implements InputFilter {
public String word;
public SpellCheckFilter()
{
word = " ";
}
//FIXME not returning corrected word. Try adjusting start/end values,
//what range does this return?
@Override
public CharSequence filter(CharSequence source, int start, int end,
Spanned dest, int dstart, int dend) {
word += source;
Log.i("SpellCheckFilter", "source=\"" + source + "\"; word=\"" + word + "\"");
if (source.toString().endsWith(" "))
{
word = word.replace(" ", "");
String correction = AutoText.get(word, 0, word.length()-1, view);
Log.i("TextEditor", "Corrected word=" + (correction == null ? word : correction));
word = " ";
return correction;
}
return null;
}
}
使用InputFilter.AllCaps,我可以获得几乎可以使用的自动大写方法,但是第一个字母没有自动大写。
最佳答案
//Calling Method
setListener1(editText);
//Method
public void setListener1(final AppCompatEditText edittext) {
final TextWatcher textWatcher = 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 s) {
String input = StringStaticMethods.firstCapital(s.toString());
edittext.removeTextChangedListener(this);
edittext.setText("");
edittext.append(input);
edittext.addTextChangedListener(this);
}
};
edittext.addTextChangedListener(textWatcher);
}
public static String firstCapital(String str) {
if (str != null && !str.equals("")) {
return (str.substring(0, 1).toUpperCase() + str.substring(1, str.length()));
}
return "";
}
//Use in XML
android:inputType="textFilter|textMultiLine|textNoSuggestions"
