import androidx.annotation.Nullable;

import com.cmmboy.toastlib.ToastUtils;
import com.jsyj.android_p1.cmm.BaseActivity;
import com.jsyj.android_p1.databinding.ActivityModelBinding;
import com.jsyj.android_p1.databinding.ActivityRadioBinding;

public class RadioActivity extends BaseActivity {

    private ActivityRadioBinding binding;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        binding = ActivityRadioBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());
        initClick();
    }

    private void initClick() {
        binding.radioButton1.setChecked(true);//默认选中
        binding.radioGroup.setOnCheckedChangeListener((group, checkedId) -> {
            if (checkedId == binding.radioButton1.getId()) {
                binding.sex.setText("男");
            } else if (checkedId == binding.radioButton2.getId()) {
                binding.sex.setText("女");
            }
        });

        binding.radioGroup2.setOnCheckedChangeListener((group, checkedId) -> {
            if (checkedId == binding.radioButton3.getId()) {
                binding.sex.setText("男");
            } else if (checkedId == binding.radioButton4.getId()) {
                binding.sex.setText("女");
            }
        });
    }
