Question

rb1=(RadioButton)findViewById(R.id.radioButton1);
rb2=(RadioButton)findViewById(R.id.radioButton2);
rb3=(RadioButton)findViewById(R.id.radioButton3);
rb4=(RadioButton)findViewById(R.id.radioButton4);
rb5=(RadioButton)findViewById(R.id.radioButton5);

spiner1=(Spinner)findViewById(R.id.spinner1);
spiner2=(Spinner)findViewById(R.id.spinner1); 

spiner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

如果我先选择1,rb2,rb3,rb5胡 display显示器和休息器,如果先选择2,3,4,5 个 value子,然后hu露出1,4,5 个pl子,告诉我如何为这种一米新 new子书写代码,并试图实施一些 app。 (一) 需要制定法律,并如何为此适用逻辑。

Answer 1

There are some demos about spinner Here is an example. you can set dropdown styles in this method

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

Answer 2

根据你的状况或逻辑,你可以显示/ide。

rb1.setVisibility(View.VISIBLE);   // show
rb2.setVisibility(View.INVISIBLE); // Hide

Answer 3

You can do this : 

spiner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> adView, View view,int pos, long id) {

              selectedoption = adapter.get(pos);

              if(selectedoption == rb1)
                    {
                     rb1.setVisibility(View.INVISIBLE);
                    }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub


        }
    });
