但是我不知道怎么会没有获取到数值，求解，代码如下：
public class GetMsgFanCActivity extends BaseActivity {
private Context mContext;
private View mBaseView;
private ListView mSettingListView;
private SharedPreferences mSp;
private List<String> itemString = new ArrayList<>();
private String TestStr;
private TextView tv_layout_title;
private Button btn_title_layout_left;
private List<ArrayList<String>>mArrayList=new ArrayList<>();
private List<GetMsgFanc> mGetMsgFanc = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_userinfo);
Intent intent = getIntent();
mContext=GetMsgFanCActivity.this;
mSp = mContext.getSharedPreferences("userInfo", mContext.MODE_WORLD_READABLE);
initEvents();
initViews();
}
@Override
protected void initViews() {
mSettingListView = (ListView)findViewById(R.id.set_list_listview);
tv_layout_title= (TextView) findViewById(R.id.tv_title_layout);
tv_layout_title.setText("获取消息界面");
}
@Override
protected void initEvents() {
init();
}
private void init(){
fetchAddrList();
}
protected void fetchAddrList()
{
this.putAsyncTask(new AsyncTask<Void, Void, Integer>() {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected Integer doInBackground(Void... voids) {
ArrayList<String> paramList = new ArrayList<String>();
ArrayList<String> valueList = new ArrayList<String>();
List<String> resaulList = new ArrayList<>();
paramList.add("DoType");
paramList.add("UserType");
paramList.add("UserId");
valueList.add("1");
valueList.add("0");
valueList.add("0");
SoapObject soapObject = WebServiceUtils.GetWebServiceInfo("GetMsgFunc", paramList, valueList);
if (soapObject != null) {
SoapObject soap1 = (SoapObject) soapObject.getProperty("GetMsgFuncResult");
if (soap1 == null || soap1.getPropertyCount() == 0) return 0;
SoapObject childs = (SoapObject) soap1.getProperty(1);
if (childs == null || childs.getPropertyCount() == 0) return 0;
SoapObject soap2 = (SoapObject) childs.getProperty(0);
if (soap2 == null) return 0;
///
Object obj = null;
for (int i = 0; i < soap2.getPropertyCount(); i++) {
SoapObject soap3 = (SoapObject) soap2.getProperty(i);
if (soap3 != null) {
//AddrInfo info = new AddrInfo();
obj = soap3.getProperty(1);
if (obj != null) {
//info.strAddr = obj.toString().trim();
itemString.add(obj.toString().trim());
//test(obj.toString().trim());
}
/*
obj = soap3.getProperty(1);
if (obj != null) {
info.strRoomName = obj.toString().trim();//校区
}
if (soap3.getPropertyCount() >= 3) {
obj = soap3.getProperty(2);
if (obj != null) {
info.strSchool = obj.toString().trim();//学校
}
}
*/
//itemString.add(info);
//DataManagerUtils.getInstance().addAddrInfoList(info);
}
}
}
return 1;
}
@Override
protected void onPostExecute(Integer integer) {
super.onPostExecute(integer);
FillListView();
//dismissLoadingDialog();
//fillAdapterList();
}
});
//.execute();
}
public void FillListView()
{
//itemString.add(TestStr);
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<>(GetMsgFanCActivity.this, android.R.layout.simple_expandable_list_item_1, itemString);
mSettingListView.setAdapter(arrayAdapter);
mSettingListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int positon, long l) {
ArrayList<String>messarraylist=new ArrayList<String>();
messarraylist= mArrayList.get(positon);
Intent intent = new Intent();
intent.setClass(GetMsgFanCActivity.this, News_Activity.class);
intent.putExtra("position", messarraylist);
startActivity(intent);
}
});
}
}
3 个解决方案
#1
mArrayList你根本就没有值，显示的值是itemString，两者的size不一样，数据不同步，肯定会越界
#2
那要怎么改
#3
public void onItemClick(AdapterView<?> adapterView, View view, int positon, long l) {
String msgStr= itemString.get(positon);
Intent intent = new Intent();
intent.setClass(GetMsgFanCActivity.this, News_Activity.class);
intent.putExtra("position", msgStr);
startActivity(intent);
}
