通过基本适配器类绑定动态文本视图时，我在对话框中遇到异常
我可以得到对话框，但它没有绑定textview值地狱..请帮助我..我做错了:)
Train_Origin_Destination.java
公共无效loadAutocomplete1（字符串strCmdTrain）{
c.moveToFirst(); if (c.isAfterLast() == false) {
do {
listFrom1 = new ArrayList<String>(Arrays.asList(strComments));
listTo1 = new ArrayList<String>(Arrays.asList(strComments));
listFrom1.removeAll(Collections.singleton(null));
HashMap<String, String> map = new HashMap<String, String>();
map.put(KEY_Start, "Hello");
listData.add(map);
Log.e("map", map.toString());
Log.e("list4", listData.toString());
customAdapter = new MyCustomAdapter2(
Train_Origin_Destination.this, listData);
lvTrainTime1.setAdapter(customAdapter);

}
