试着用jlhonora MultistateToggle Library来实现上面的东西
getValue（）是返回索引号的方法，这样您就可以轻松地识别用户选择了什么

public class AddListingForm extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add_listing_form);

    final MultiStateToggleButton toggleButton= (MultiStateToggleButton) 
this.findViewById(R.id.MSTB);

// With an array
   CharSequence[] states= new CharSequence[]{"Lowercase","Uppercase", 
"Both"};
    toggleButton.setElements(states);

    toggleButton.setOnValueChangedListener(new ToggleButton.OnValueChangedListener() {
        @Override
        public void onValueChanged(int position) {

            property_type = states[position].toString();

        }
    });

 int a=toggleButton.getValue(); 
  // if User selected Lowercase then you will  get value of a is 0 
 //  Similarly for Uppercase a will be 1 and for Both a will be 2

}
}
