Question

这是我的活动：

et.addTextChangedListener(mTextEditorWatcher);


private final TextWatcher mTextEditorWatcher = new TextWatcher() {

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


    }

    public void onTextChanged(CharSequence s, int start, int before, int count)
    {
        String name =et.getText().toString();
        String a ="a";
        String b ="b";
        String c ="c";
        String d ="d";
        String e ="e";
        String f ="f";
        String g ="g";
        String h ="h";
        String a1 ="\u24B6";
        String b1 ="\u24B7";
        String c1 ="\u24B7";
        String d1 ="\u24B9";
        String e1 ="\u24BB";
        String f1 ="\u24BB";
        String g1 ="\u24BD";
        String h1 ="\u24BD";
        name =name.replaceAll(a,a1);
        name =name.replaceAll(b,b1);
        name =name.replaceAll(c,c1);
        name =name.replaceAll(d,d1);
        name =name.replaceAll(e,e1);
        name =name.replaceAll(f,f1);
        name =name.replaceAll(g,g1);
        name =name.replaceAll(h,h1);
        tv.setText(name);
    }

    public void afterTextChanged(Editable s)
    {
        et.removeTextChangedListener(this);

        et.addTextChangedListener(this);

    }
};

在edittext textview中显示空格中的a或b或c是什么解决方案显示unicode？请帮忙

您可以尝试：

 var validateFields = function(o, required_fields) {
  required_fields.forEach(function(field){
    if(field in o){
      if((typeof o[field] != 'undefined')){
        console.log(field + ": " + o[field]);
      }else{
        console.log(field + " exists but is undefined");
      }
    }else{
      console.log(field + " doesn't exist in object");
    }
  });
}
