我的代码中有15个微调器，它们应该从我已创建的数组中获取值。代码如下;
private double[] grade_values = {-100000.0, 5.0, 4.0, 3.0, 2.0, 1.0, 0.0};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ece_second_year_second_semester);
spinner_ids = new int[15];
spinner_check = 0;
spinner_index = 0;
String[] grades = getResources().getStringArray(R.array.grades);
spinner0 = (Spinner) findViewById(R.id.spinner0);
spinner1 = (Spinner) findViewById(R.id.spinner1);
spinner2 = (Spinner) findViewById(R.id.spinner2);
spinner3 = (Spinner) findViewById(R.id.spinner3);
spinner4 = (Spinner) findViewById(R.id.spinner4);
spinner5 = (Spinner) findViewById(R.id.spinner5);
spinner6 = (Spinner) findViewById(R.id.spinner6);
spinner7 = (Spinner) findViewById(R.id.spinner7);
spinner8 = (Spinner) findViewById(R.id.spinner8);
spinner9 = (Spinner) findViewById(R.id.spinner9);
extraSpinner0 = (Spinner) findViewById(R.id.extra_spinner0);
extraSpinner1 = (Spinner) findViewById(R.id.extra_spinner1);
extraSpinner2 = (Spinner) findViewById(R.id.extra_spinner2);
extraSpinner3 = (Spinner) findViewById(R.id.extra_spinner3);
extraSpinner4 = (Spinner) findViewById(R.id.extra_spinner4);
spinner0.setOnItemSelectedListener(this);
spinner1.setOnItemSelectedListener(this);
spinner2.setOnItemSelectedListener(this);
spinner3.setOnItemSelectedListener(this);
spinner4.setOnItemSelectedListener(this);
spinner5.setOnItemSelectedListener(this);
spinner6.setOnItemSelectedListener(this);
spinner7.setOnItemSelectedListener(this);
spinner8.setOnItemSelectedListener(this);
spinner9.setOnItemSelectedListener(this);
extraSpinner0.setOnItemSelectedListener(this);
extraSpinner1.setOnItemSelectedListener(this);
extraSpinner2.setOnItemSelectedListener(this);
extraSpinner3.setOnItemSelectedListener(this);
extraSpinner4.setOnItemSelectedListener(this);
each_grade = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, grades);
each_grade.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner0.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected,this));
spinner1.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected,this));
spinner2.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected,this));
spinner3.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected,this));
spinner4.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected,this));
spinner5.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected,this));
spinner6.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected,this));
spinner7.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected,this));
spinner8.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected,this));
spinner9.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected,this));
extraSpinner0.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected, this));
extraSpinner1.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected, this));
extraSpinner2.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected, this));
extraSpinner3.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected, this));
extraSpinner4.setAdapter(new NothingSelectedSpinnerAdapter(each_grade, R.layout.contact_spinner_row_nothing_selected, this));
}
以“额外”命名的旋转器将其可见性设置为GONE但是我有一个按钮，使每个都可以看到。即按一次额外出现，按两次，另一次加入第一次，依此类推，直到五次完成。
onItemSelected方法如下;
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
int b = parent.getId();
if (spinner_index < 15) {
spinner_ids[spinner_index] = b;
spinner_index++;
}
setSpinner(b, position);
}
public void setSpinner(int spin_id, int value) {
if (spin_id == spinner_ids[0])
gpa_grade_0 = grade_values[value];
else if (spin_id == spinner_ids[1])
gpa_grade_1 = grade_values[value];
else if (spin_id == spinner_ids[2])
gpa_grade_2 = grade_values[value];
else if (spin_id == spinner_ids[3])
gpa_grade_3 = grade_values[value];
else if (spin_id == spinner_ids[4])
gpa_grade_4 = grade_values[value];
else if (spin_id == spinner_ids[5])
gpa_grade_5 = grade_values[value];
else if (spin_id == spinner_ids[6])
gpa_grade_6 = grade_values[value];
else if (spin_id == spinner_ids[7])
gpa_grade_7 = grade_values[value];
else if (spin_id == spinner_ids[8])
gpa_grade_8 = grade_values[value];
else if (spin_id == spinner_ids[9])
gpa_grade_9 = grade_values[value];
else if (spin_id >= spinner_ids[10])
new_gpa_grade_0 = grade_values[value];
else if (spin_id >= spinner_ids[11])
new_gpa_grade_1 = grade_values[value];
else if (spin_id >= spinner_ids[12])
new_gpa_grade_2 = grade_values[value];
else if (spin_id >= spinner_ids[13])
new_gpa_grade_3 = grade_values[value];
else
new_gpa_grade_4 = grade_values[value];
}
现在的问题是，当我添加一个extraSpinner时，它正确地收到了值。但是当我添加另一个时，前一个不再起作用，因为这个新值取值。 gpa_grade_9之前的'else if'语句工作正常，但对于new_gpa_grades，添加的最后一个使得之前添加的语句停止工作并给出错误的答案。
有关如何设置onItemSelectedListener或修复我的代码的任何更好的想法将不胜感激。感谢。
