需求場(chǎng)景舉例：新增地址中地址標(biāo)簽屬性 家/學(xué)校/公司 三選一 點(diǎn)擊選中的取消選擇

實(shí)現(xiàn)方式：繼承AppCompatRadioButton敢朱，重寫toggle方法。上代碼:

public class XXXButton extends AppCompatRadioButton {
    public XXXButton (Context context) {
        this(context, null);
    }

    public XXXButton (Context context, AttributeSet attrs) {
        this(context, attrs, R.attr.radioButtonStyle);
    }

    public XXXButton (Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public void toggle() {
        setChecked(!isChecked());
        if (!isChecked()) {
            ((RadioGroup) getParent()).clearCheck();
        }
    }
}

xml使用

<RadioGroup
                android:id="@+id/radioGroup"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginStart="30dp"

                    android:layout_width="wrap_content"
                    android:layout_height="24dp"
                    android:background="@drawable/comment_stu_bg"

                    android:layout_width="wrap_content"
                    android:layout_height="24dp"

                <com.a.b.XXXButton 
                    android:id="@+id/rb_school"

                    android:layout_height="24dp"
                    android:layout_marginStart="15dp"
                    android:background="@drawable/comment_stu_bg"

                    android:text="學(xué)校"
                    android:textColor="@drawable/comment_stu_tv_bg"
                    android:textSize="13sp" />

            </RadioGroup>

Activity中監(jiān)聽

radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                switch (checkedId) {
                    case R.id.rb_home:
                        lable = 0;
                        break;
                    case R.id.rb_company:
                        lable = 1;
                        break;
                    case R.id.rb_school:
                        lable = 2;
                        break;
                    default:
                        lable = -1;
                        break;
                }
            }
        });
