您可以首先从单选组中获取所选
单选按钮的ID,然后在获取ID后,您可以获取所选单选按钮的文本,然后您可以添加它们或执行任何您想要的操作
下面的代码假设您的单选按钮
的整数值为文本,即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();
}
});
希望有帮助。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;
当你选择一个收音机按钮时,你想显示祝酒词当我点击“计算”按钮时,你不想显示祝酒词请勾选我的答案注意,你的文字不是纯整数。我会让你的单选按钮的文本值是整数。那么这就行了,谢谢你的纠正。我认为单选按钮值是整数,因为他在Toast.makeText中添加字符串值(键入\ u Installation.this,“您的组合是”+result+“W”,Toast.LENGTH\ u SHORT).show();
