onClickListener调用TextWatcher：非法的前向引用

Question

View.OnClickListener radio1Clicked = v ->{
        radioButton1.addTextChangedListener(textWatcher); //error under textWatcher : Illegal forward reference
        //More Operations Running here ... };

View.OnClickListener radio2Clicked = v ->{ 
        radioButton2.addTextChangedListener(textWatcher)};//error under textWatcher: Illegal forward reference
        //More Operations Running here ... };

View.OnClickListener radio3Clicked = v ->{ 
        radioButton2.addTextChangedListener(textWatcher)};//error under textWatcher: Illegal forward reference
        //More Operations Running here ... };

    TextWatcher textWatcher= new TextWatcher(){
        //Declarations and other stuff
                // RadioButton1
                if (radioButton1.isChecked()) {
                    basePrintable = 50;
                    calculatePcs = (int) (50 / sqIn);
                    iPieces.setText(String.valueOf(calculatePcs ));
                    if (!checker)//check Switch {
                        iPriceOut.setText("150.0");
                    } else if (checker) //re-check Switch{
                        iPriceOut.setText("50.0");
                    }
                }
                // RadioButton1
                if (radioButton1.isChecked()) {
                    basePrintable = 50;
                    calculatePcs = (int) (50 / sqIn);
                    iPieces.setText(String.valueOf(calculatePcs ));
                    if (!checker)//check Switch {
                        iPriceOut.setText("150.0");
                    } else if (checker) //re-check Switch{
                        iPriceOut.setText("50.0");
                    }
                }
                // RadioButton2
                if (radioButton1.isChecked()) {...}
                // RadioButton3
                if (radioButton1.isChecked()) {...}


     basePcs = Integer.parseInt(iPieces.getText().toString());
                baseSheet = 
     Integer.parseInt(iShit.getText().toString());
                basePrice = 
     Double.parseDouble(iPriceOut.getText().toString());
    }

public void onCheckedChanged(CompoundButton switchInput, boolean isChecked) {
        switchInput.addTextChangedListener(size);
        if (!isChecked) {
            switchInput.setText("...");
            radioButton1.setText("...");
            radioButton2.setText("...");
            radioButton3.setText("...");
        } else {
            switchInput.setText("...");
            radioButton1.setText("...");
            radioButton2.setText("...");
            radioButton3.setText("...");
        }
    }

谢谢你的帮助

我认为问题是您不能引用在里面单击的对象，而是使用传递的视图

View.OnClickListener o1 = v ->{
        iOpt1.addTextChangedListener(size); //error: Illegal Forward Reference
        if (iOpt1.isChecked()) {
            iOpt2.setChecked(false);
            iOpt3.setChecked(false);
        }
        iOpt1.setChecked(true);
    };

改为

View.OnClickListener o1 = v ->{
        v.addTextChangedListener(size); <--change here //error: Illegal Forward Reference
        if (v.isChecked()) { <--change here
            iOpt2.setChecked(false);
            iOpt3.setChecked(false);
        }
        v.setChecked(true);<--change here
    };

在单击视图时使用v
