我有一个Android应用程序。在这个应用程序中，我使用自定义SimpleCursorAdapter的AutoCompleteTextView。在AutoCompleteTextView中，addTextChangedListener的onTextChanged方法，
我在代码
下面使用SearchFeedResultsAdaptorCustomer mSearchViewAdapter = new SearchFeedResultsAdaptorCustomer(this.getActivity(), R.layout.searchview_customer, null,
columns, null, -1000);
textView = (AutoCompleteTextView) mRoot.findViewById(R.id.search_box);
textView.setAdapter(mSearchViewAdapter);
textView.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
try {
loadData(s.toString());
} catch (JSONException e) {
e.printStackTrace();
}
textView.setAdapter(mSearchViewAdapter);
}
@Override
public void afterTextChanged(Editable s) {
}
});
loadData方法是：
private void loadData(String searchText) throws JSONException {
ArrayList<JSONObject> filterCustomers = new ArrayList<>();
if (searchText == null || searchText == "") {
filterCustomers = prgmNameList;
} else {
int i = 0;
for (JSONObject customer : prgmNameList) {
if (customer.getString("fullName").toUpperCase().contains(searchText.toUpperCase())) {
filterCustomers.add(customer);
}
}
}
Log.e("searchhh", "load data" + filterCustomers.size());
MatrixCursor matrixCursor = convertToCursor(filterCustomers);
mSearchViewAdapter.changeCursor(matrixCursor);
}
private MatrixCursor convertToCursor(ArrayList<JSONObject> customerList) throws JSONException {
MatrixCursor cursor = new MatrixCursor(columns);
int i = 0;
for (JSONObject customer : customerList) {
String[] temp = new String[8];
i = i + 1;
temp[0] = "" + i;
temp[1] = String.valueOf(customer.getString("accountNumber"));
temp[2] = String.valueOf(customer.getString("address"));
temp[3] = String.valueOf(customer.getString("email"));
temp[4] = String.valueOf(customer.getString("fullName"));
temp[5] = String.valueOf(customer.getString("mobile"));
float point;
if (customer.getString("earn_point") == null) {
point = 0;
} else {
point = Float.parseFloat(customer.getString("earn_point").toString());
}
temp[6] = String.valueOf(point);
temp[7] = String.valueOf(customer.getString("uid"));
cursor.addRow(temp);
}
return cursor;
}
它将数据显示为下拉列表，但是当我点击列表项时，我收到了以下错误。
以下是我的点击项方法：
textView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("Position", "pos:"+position);
Cursor cursor = (Cursor) parent.getItemAtPosition(position);
//or
//Cursor cursor = (Cursor) parent.getItem(position);
//MatrixCursor matrix = (MatrixCursor)parent.getItemAtPosition(position);
cursor.moveToPosition(position);
Log.e("Position", "pos:"+cursor.getCount());
String feedName = cursor.getString(1);
searchView.setQuery("", false);
searchView.clearFocus();
name.setText(cursor.getString(4));
mobile.setText(cursor.getString(5));
email.setText(cursor.getString(3));
point.setText(cursor.getString(6));
account.setText(cursor.getString(7));
usepontHidden.setText(String.valueOf(0));
}
});
以下是错误消息：
