我有一个RadioGroup中rg1 ，我想选择的单选按钮的值。
我知道，我能得到id使用选择的单选按钮：
if(rg1.getCheckedRadioButtonId()!=-1)
int id= rg1.getCheckedRadioButtonId()
这给了我的ID，但我想这个按钮的值。
Answer 1:
你需要一个索引处得到的单选按钮，然后得到那个按钮上的文字的值。 下面试试这个代码。
if(rg1.getCheckedRadioButtonId()!=-1){
int id= rg1.getCheckedRadioButtonId();
View radioButton = rg1.findViewById(id);
int radioId = radioGroup.indexOfChild(radioButton);
RadioButton btn = (RadioButton) rg1.getChildAt(radioId);
String selection = (String) btn.getText();
}
Answer 2:
试试这个：
RadioGroup rg = (RadioGroup)findViewById(R.id.youradio);
String radiovalue = ((RadioButton)findViewById(rg.getCheckedRadioButtonId())).getText().toString();
Answer 3:
RadioGroup rg = (RadioGroup)findViewById(R.id.youradio);
String radiovalue = (RadioButton)this.findViewById(rg.getCheckedRadioButtonId())).getText().toString();
Answer 4:
一号线码
String buisnesstype = ((RadioButton) rdtranscompany.findViewById(rdtranscompany.getCheckedRadioButtonId())).getText().toString();
Answer 5:
rb1=(RadioButton)findViewById(rg1.getCheckedRadioButtonId());
现在你可以使用rb1.getText()来获取被选中的单选框文本
Answer 6:
我想你应该试试这个
RadioGroup rg=(RadioGroup)findViewById(R.id.youradio);
String radiovalue=(RadioButton)this.findViewById(rg.getCheckedRadioButtonId())).getText().toString();
Answer 7:
RadioGroup bhktype_RadioGr = (RadioGroup)findViewById(R.id.bhkypeRadioGroup);
int flatTypeId = bhktype_RadioGroup.getCheckedRadioButtonId();
String flat_type = ((RadioButton) findViewById(flatTypeId)).getText().toString();
Answer 8:
简单的答案一行
View v = yourView; // as a button
String radiovalue = (RadioButton)v).getText().toString();
