如何添加两个单选按钮的值？

Question

我有两个 radioGroups，每个都包含不确定数量的 radioButton 我想在 radioGroup 1 中添加 radioButton selected 的值，在radioGroup 2 并在 toast 中显示结果。我尝试了下面的代码，但它似乎不起作用

请问我该怎么做？

我的尝试：

RadioButton lamp1;
RadioButton tele1;
RadioGroup group, group2;
Button button;
int result;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_type_installation);

    addListenerOnButton();
}

public void addListenerOnButton() {

    group = findViewById(R.id.group);
    group2 = findViewById(R.id.group2);

    ampoule1 = findViewById(R.id.lamp1);
    tele1 = findViewById(R.id.tele1);

    button = findViewById(R.id.calcul);
    button.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            int selectedId = group.getCheckedRadioButtonId();
            int selectedId1 = group2.getCheckedRadioButtonId();

            ampoule1 = findViewById(selectedId);
            tele1 = findViewById(selectedId1);

            result = selectedId+selectedId1;
            Toast.makeText(Type_Installation.this, "your consommation is"
                    +result+"W", Toast.LENGTH_SHORT).show();
        }
    });
}

XML代码：

Answer 1

你可以先从radio groups中获取selected radio button的id，获取id后，你可以获取selected radio button的text，然后你就可以添加它们或做任何事情你要。

下面的代码假定您的 radio buttons 具有整数值作为文本 i.e 5,6,7

button.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {

        // get selected radio button from radioGroup
        int selectedId1 = group.getCheckedRadioButtonId();
        int selectedId2 = group2.getCheckedRadioButtonId();

        // find the radiobutton by returned id
        RadioButton radioButton1 = (RadioButton) findViewById(selectedId1);
        RadioButton radioButton2 = (RadioButton) findViewById(selectedId2);


        //Assuming text on radio buttons are integer values like 5.6.7 etc

        int result = Integer.parseInt(radioButton1.getText())+Integer.parseInt(radioButton2 .getText());


        Toast.makeText(MyAndroidAppActivity.this,
            "Resulkt"+result, Toast.LENGTH_SHORT).show();
    }
});

希望对您有所帮助。

Answer 2

使用了这些代码行

 lamp1 = findViewById(selectedId);
  tele1 = findViewById(selectedId1);
  result = Integer.valueOf(lamp1.getText().toString())+Integer.valueOf(tele1.getText().toString());

而不是这个

ampoule1 = findViewById(selectedId);
tele1 = findViewById(selectedId1);
 result = selectedId+selectedId1;
