如何实现代码控制RadioGroup中某一个按钮选中

Posted 2023-03-24

参考技术A mButton1 = (RadioButton)findViewById(R.id.radioButton1);
mButton2 = (RadioButton)findViewById(R.id.radioButton2);

mButton1.setOnCheckedChangeListener(new OnCheckedChangeListener()
@Override
public void onCheckedChanged(CompoundButton arg0, boolean arg1)
if(arg1)
Toast.makeText(getApplicationContext(),"1 first click 1",0).show();
mButton2.setChecked(false);


);
mButton2.setOnCheckedChangeListener(new OnCheckedChangeListener()
@Override
public void onCheckedChanged(CompoundButton arg0, boolean arg1)
if(arg1)
Toast.makeText(getApplicationContext(),"2 first click 1",0).show();
mButton1.setChecked(false);
