我有两个微调器，比如类别和子类别。 OnItemSelected类别微调器我需要为sub_categories spinner设置适配器。我能够为类别设置微调器。但sub_categories微调器正在制造麻烦。
这些arraylist来自服务器，我把它变成了静态的。 查看我的代码会让你正确地知道我错在哪里。
这是我的分类列表：
public static ArrayList<String> categories=new ArrayList<String>();
public static ArrayAdapter<String> mArryAdtSpnnr;
并在response.success中，我尝试执行以下操作：
for(int i=0;i<mArray.length;i++){categories.add(mArray[i].getName());}
在此活动中，我需要2个微调器：
private void initializeWidgets() {
mspinner_categories=(Spinner)findViewById(R.id.spinner_categories);
mspinner_categories.setOnItemSelectedListener(this);
mspinner_subcategories=(Spinner)findViewById(R.id.spinner_subcategories);
ProfessionalListActivity.mArryAdtSpnnr = new ArrayAdapter<String>( EditProfileActivity.this,
android.R.layout.simple_spinner_item,ProfessionalListActivity.categories);
mspinner_categories.setAdapter(ProfessionalListActivity.mArryAdtSpnnr);
}
并选择其项目：
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String item = parent.getItemAtPosition(position).toString();
Toast.makeText(EditProfileActivity.this,"Selected Item is: "+item,Toast.LENGTH_LONG).show();
// mspinner_subcategories.setSelection(position);
SubListProActivity.mArrySpnnr=new ArrayAdapter<String>
(EditProfileActivity.this,android.R.layout.simple_spinner_item,
SubListProActivity.subcategories);
mspinner_subcategories.setAdapter(SubListProActivity.mArrySpnnr);
}
我在点击第一个微调器时设置第二个微调器适配器。但是这个微调器没有显示任何东西。我对其他活动做了类似的代码。 我很困惑，这可能是因为在ProfessionalListActivity中我也得到了category_id，因此相应的子列表被打开了。但在旋转器中，我直接添加它。 编辑： 子列表类：
public static ArrayList<String> subcategories=new ArrayList<String>();
public static ArrayAdapter<String> mArrySpnnr;
在其response.success中
for(int i=0;i<mArray.length;i++){
subcategories.add(mArray[i].getName());
}
请帮忙

此代码以ExpandableList的形式处理您的问题，来自正在运行的应用。首先是调用以下活动的按钮的监听器：
原始申请是一个（农业）检查系统 - 用户从问题组（第一级：昆虫，真菌，杂草）中选择，发生了哪些问题（第二级：昆虫[陆军蠕虫，瓢虫，蚂蚁]，真菌[茎腐病，锈病，霉病]，杂草[普通草，非洲草，牵牛花]）。
对于每个选定的第二级选项，会弹出一个用于选择问题严重性的单选按钮组，用户必须选择级别1（默认），2或3。
存储数据以供其他地方使用。
调用显示专用于INSPECTION的布局的活动，发送将填充可扩展列表的数据。
private final OnClickListener btnDoneOnClick = new OnClickListener() {
public void onClick(View v) {
String input = areaName.getText().toString();
// english version
//String[] groupName = {"INSECTS", "WEEDS", "FUNGHI", "CLIMATE", "VARIOUS"};
String[] groupName = {"INSETOS", "ERVAS INVASORAS", "FUNGOS", "CLIMA", "VARIOS"};
String[][] childName = { { "Cigarrinha","Falsa medideira","Lagarta cartucho","Lagarta rosca","Percevejo (geral)"},
{ "Argentino","Buva","Capim colchao","Carrapicho","Corda viola","Falso Argentino","Leiteiro","Picao","Tiguera Milho","Tiguera Soja"},

{ "Erosao","Geada","Granizo","Incendio","Inundacao","Raio","Seca","Vento" },
{ "Furto","Fuga","Picada cobra" }
};
Intent intent00 = new Intent(getApplicationContext(), com.xxx.yyy.zzz.AgrInspectActivity.class);
intent00.putExtra("groupName", groupName);
int maxLength = 0;
for (int i=0;i<groupName.length;i++) {
intent00.putExtra(groupName[i], childName[i]);
maxLength = Math.max(childName[i].length, maxLength);
}
intent00.putExtra("arrayLength", maxLength);
// count childrenRows and put values in ARRAY
// to be used by CustomList to inflate layouts
// with proper number of lines
int[] countChild = new int[groupName.length];
for (int j=0;j<groupName.length;j++) {
countChild[j] = childName[j].length;
}
intent00.putExtra("countChild", countChild);
startActivity(intent00);
}
