RadioButtons android发送数据

Question

所以我在这里有一个问题。我想实现一个有三个单选按钮的活动

rb1

rb2

rb3

还有一个按钮提交。 When any one of those are selected and the button is clicked, it should send an int value to the next activity.例如，如果选择了 rb2 并且我点击了按钮提交，它应该发送 int 值 10。但是如果选择了 rb3 并且onClick，它应该发送 14 到下一个 Activity。

该怎么做呢？这是我当前的代码

public void onRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();

// Check which radio button was clicked
switch(view.getId()) {
    case R.id.radio_btn1:
        if (checked)
            // Send value 10 to the next activity
        break;
    case R.id.radio_btn2:
        if (checked)
            // Send value 14 to the next activity
        break;
     }
}

Answer 1

这是一个例子

public void onRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();

// Check which radio button was clicked
switch(view.getId()) {
    case R.id.radio_btn1:
        if (checked)
            // Send value 10 to the next activity
        Intent intent = new Intent(this, TheActivityYouWantToStart.class);
        intent.putExtra("number", 10);
        startActivity(intent);
        break;
    case R.id.radio_btn2:
        if (checked)
            // Send value 14 to the next activity
        break;
     }
}

要在下一个活动中获取数字，您必须像这样从 Intent 获取它

 @Override
    protected void onCreate(Bundle savedInstanceState) {
       int number = getIntent().getIntExtra("number", 999); // 999 is default value
    }

Answer 2

int valueToBeSent= -1;
switch(view.getId()) {
case R.id.radio_btn1:
    if (checked)
        valueToBeSent = 10;
    break;
case R.id.radio_btn2:
    if (checked)
        valueToBeSent = 14;
    break;
}
if(valueToBeSent!=-1) {
Intent intent = new Intent(_context, NextActivityName.class);
    intent.putExtra("selectedValue", valueToBeSent);
    startActivity(intent);
}
