android - TextWacher() 在 android 中编写 unicode(Sindhi) 的问题

Question

我想用这种方式写unicode字符：EditText

final EditText et = (EditText) findViewById(R.id.editText1);
    TextWatcher tw = new TextWatcher() {
        public void afterTextChanged(Editable s){

        }
        public void  beforeTextChanged(CharSequence s, int start, int count, int after){

        }
        public void  onTextChanged (CharSequence s, int start, int before,int count) {
            if(s.equals("a")){
                et.append("\u0627");
            }
        } 
    };

    et.addTextChangedListener(tw);

但这只会写英文chracter，EditText如何解决这个问题。提前致谢。

试试这个方法可能对你有帮助

EditText edt = (EditText) findViewById(R.id.edt);


        InputFilter filter = new InputFilter() {

            @Override
            public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
                if(source.toString().equals("a")){
                    return "\u0627";
                }

                return null;

            }
        };

        edt.setFilters(new InputFilter[]{filter});

输出
