如何在微调器数组中显示所有元素？

Question

我有以下代码。当我运行我的程序时，我只在spinner下拉列表中获得一个元素。

String[] DayOfWeek = {"Sunday", "Monday", "Tuesday", 
                               "Wednesday", "Thursday", "Friday", "Saturday"};
spinnerCountShoesArrayAdapter = new ArrayAdapter<String>(
                            PatientRegistration.this,
                            android.R.layout.simple_spinner_dropdown_item,
                            getResources()
                                    .getStringArray(R.array.locality_contents));
spinnerCountShoesArrayAdapter = new ArrayAdapter<String>(
                            PatientRegistration.this,
                            android.R.layout.simple_list_item_1, DayOfWeek);    

b.setAdapter(spinnerCountShoesArrayAdapter);

试试此代码

                               "Wednesday", "Thursday", "Friday", "Saturday"};
ArrayAdapter<String> spinnerCountShoesArrayAdapter = new ArrayAdapter<String>(
                            PatientRegistration.this,
                            android.R.layout.simple_spinner_item, DayOfWeek);    
      spinnerCountShoesArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
b.setAdapter(spinnerCountShoesArrayAdapter);

只需添加以下代码行，即可使用

String[] DayOfWeek = {"Sunday", "Monday", "Tuesday", 
                               "Wednesday", "Thursday", "Friday", "Saturday"};
spinnerCountShoesArrayAdapter = new ArrayAdapter<String>(
                            PatientRegistration.this,
                            android.R.layout.simple_dropdown_item_1line);

for (int i = 0; i < DayOfWeek.length(); i++) {
                        spinnerCountShoesArrayAdapter.add(DayOfWeek[i]);
            }

b.setAdapter(spinnerCountShoesArrayAdapter);
