android单选按钮

Posted 2023-03-07

为什么这样不行呢？还是可以同时选中3个按钮，我只想单选....QQ385811416 public class seshi extends Activity TextView x_View; RadioGroup x_Group; RadioButton b1,b2,b3; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.main); x_View = (TextView)findViewById(R.id.tt1); x_Group = (RadioGroup)findViewById(R.id.gg1); b1 = (RadioButton)findViewById(R.id.bb1); b2 = (RadioButton)findViewById(R.id.bb2); b3 = (RadioButton)findViewById(R.id.bb3);

参考技术A 你要当成单选的一组的radiobutton要放在radioGROUP下，不然这个GROUP就没起作用
只有这样写，才能实现这组radiobutton是单选的效果。
