RadioButton 和RadioGroup

在这里插入图片描述

public class MainActivity extends AppCompatActivity {

    private RadioButton girl_radiobutton, boy_radiobutton;
    private Button button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //实例化控件
        init();

    }
    //实例化控件
    private void init() {

        button = findViewById(R.id.button);
        girl_radiobutton = findViewById(R.id.girl_radiobutton);
        boy_radiobutton = findViewById(R.id.boy_radioButton);
        //确定按钮点击事件
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                    //判断 RadioButton 是否选中，处理结果
                    if (girl_radiobutton.isChecked()) {
                        Toast.makeText(getApplication(), girl_radiobutton.getText() + " ", Toast.LENGTH_SHORT).show();
                    } else if (boy_radiobutton.isChecked()) {
                        Toast.makeText(getApplication(), boy_radiobutton.getText() + " ", Toast.LENGTH_SHORT).show();
                    } else {
                        Toast.makeText(getApplication(), " 请选择性别 ", Toast.LENGTH_SHORT).show();
                    }

            }
        });

    }
