Answer 2

在Spiner我们有setOnItemSelectedListener

        String temp [];
        Spinner s1=null;
        String materialType;

        temp = getResources().getStringArray(R.array.material_type);
            materialType = s1.getSelectedItem().toString();
            ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getApplicationContext(),
                    R.array.material_type, android.R.layout.simple_spinner_item);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            s1.setAdapter(adapter);


            s1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                    materialType= temp[position];

                }

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

                }
            });
