    final EditText phone=(EditText)findViewById(R.id.phone_number);
    final EditText address=(EditText)findViewById(R.id.address);
    final RadioGroup shapes = (RadioGroup) findViewById(R.id.rBtnshapes);
    final RadioGroup types = (RadioGroup) findViewById(R.id.rBtntypes);
    final CheckBox pep = (CheckBox)findViewById(R.id.pepperoni);

            RadioButton sh = (RadioButton)findViewById(selectedShape);
            RadioButton ty=(RadioButton)findViewById(selectedCheese);
            Toast.makeText(MainActivity.this, "Name: "+name.getText()+"\n"+"Phone: "+phone.getText()+"\n"+"Address: " +address.getText()+"\n"+"Shape: "+sh.getText()+"\n"+"Cheese: "+ty.getText()+"\n"+"Toppings: "+result.toString(), Toast.LENGTH_SHORT).show();

我猜您希望选中的复选框显示为图像

orderBtn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                StringBuffer result = new StringBuffer();

                int selectedShape = shapes.getCheckedRadioButtonId();
                int selectedCheese = types.getCheckedRadioButtonId();
                RadioButton sh = (RadioButton)findViewById(selectedShape);
                RadioButton ty=(RadioButton)findViewById(selectedCheese);

                final CheckBox pep = (CheckBox)findViewById(R.id.pepperoni);
                final CheckBox mshr = (CheckBox)findViewById(R.id.mushrooms);

                if(pep.isChecked()==true){

                      result.append("Pepperoni"+"\n");
                }
                  if(mshr.isChecked()==true){

                  result.append("Mushrooms"+"\n");
              }


                Toast.makeText(MainActivity.this, "Name: "+name.getText()+"\n"+"Phone: "+phone.getText()+"\n"+"Address: " +address.getText()+"\n"+"Shape: "+sh.getText()+"\n"+"Cheese: "+ty.getText()+"\n"+"Toppings: "+result.toString(), Toast.LENGTH_SHORT).show();
            }
        });

Answer 2

我认为，而不是

orderBtn.setOnClickListener(new View.OnClickListener()

使用：

orderBtn.setOnCheckedChangeListener(new OnCheckedChangeListener() ...

Doc此方法将检查用户是否选中或取消选中对话框

Answer 3

为复选框生成listner并输入条件并检查checkbox的位置是否已检查@

pep.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if(isChecked){
                    String temp=buttonView.getText().toString();
                }

            }
        });

然后附加String to StringBuffer并将结果传递给Toast消息。
