Answer 1

您可以通过在第3个微调器的底部添加另一个微调器并使其能见度= false来实现此目的，当您在第3个微调器中选择特定值时（可以通过onItemSelectedListener获得此值），使第4个微调器能见度= true，否则使能见度= false。

Yes as @Mohan suggested, by adding another spinner4 at bottom of spinner3 and make visibility = false, when you select particular value in spinner3 (you can get this by onItemSelectedListener), make spinner4 visibility = true, or else visibility = false. Here is a sample code:

spinner3.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                    if (position==particularPosition){
                        spinner4.setVisibility(View.VISIBLE);
                    }else {
                        spinner4.setVisibility(View.GONE);
                    }
                }

                @Override
                public void onNothingSelected(AdapterView<?> parent) {

                }
            });
