ListView
私はこの方法でaを埋める簡単なアダプターを持っています:
adapter = new SimpleAdapter(this, mylist ,
R.layout.itemlist, new String[] { "item1", "items2" },
new int[] { R.id.item_id, R.id.item_title });
私は自分のコードを調整し、hashmap<string, hashmap<string,string>>
今持っています、そして私はそれをに渡すことができませんnew string[]{"item1","item2"};
これをどのように解決すればよいですか?
これが私のXML構造です:
<groups>
<group>
<id>...</id>
<name>...</name>
<description>...</description>
<actions>
<action>...</action>
<action>...</action>
</actions>
</group>
<group>
<id>...</id>
<name>...</name>
<description>...</description>
<actions>
<action>...</action>
<action>...</action>
<action>...</action>
</actions>
</group>
<group>
<id>...</id>
<name>...</name>
<description>...</description>
<actions>
<action>...</action>
</actions>
</group>
</groups>
私が準備したが行き詰まったコードはこれでした:
public class ErrorCodeList extends ListActivity {
public static final String LANGUAGE = null;
public ArrayList<HashMap<String, String>> mylist;
public ListAdapter adapter;
public Dialog progDialog;
public ProgressBar progBar;
public TextView lblMessage;
private Intent myIntent;
private String URLvariable;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listplaceholder);
myIntent = getIntent();
URLvariable = myIntent.getExtras().getString("urlType");
mylist = new ArrayList<HashMap<String, String>>();
adapter = new SimpleAdapter(this, mylist , R.layout.activity_error_list,
new String[] { "tid", "tname" },
new int[] { R.id.item_id, R.id.item_title });
final ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
@SuppressWarnings("unchecked")
HashMap<String, String> hashMap = (HashMap<String, String>) lv.getItemAtPosition(position);
Intent myIntent = new Intent(view.getContext(),ErrorCodeDetails.class);
myIntent.putExtra("map",hashMap);
startActivity(myIntent);
}
});
progDialog = new Dialog(this, R.style.progress_dialog);
progDialog.setContentView(R.layout.progress_dialog);
progBar = (ProgressBar) progDialog.findViewById(R.id.progBar);
lblMessage = (TextView) progDialog.findViewById(R.id.txtProgMessage);
lblMessage.setText("Please Wait.....");
progDialog.show();
new GetDataTask().execute();
}
private Boolean isOnline() {
ConnectivityManager cm = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();
if(ni != null && ni.isConnected())
return true;
return false;
}
private class GetDataTask extends AsyncTask<Void, Void, Integer> {
@Override
protected Integer doInBackground(Void... params) {
if(isOnline()){
mylist.clear();
}
// Start the http request
String feedURL="http://...";
String xml = XMLfunctions.getXML(feedURL);
Document doc = XMLfunctions.XMLfromString(xml);
int numResults = 1;
if((numResults <= 0)){
Toast.makeText(ErrorCodeList.this, "Geen resultaten gevonden", Toast.LENGTH_LONG).show();
finish();
}
NodeList troubles = doc.getElementsByTagName("trouble");
for (int i = 0; i < troubles.getLength(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element)troubles.item(i);
if((e.getAttributes().getNamedItem("type").getNodeValue().equals("error"))) {
//map.put("id", "ID:" + Integer.valueOf(e.getAttributes().getNamedItem("id").getNodeValue()));
//map.put("status", "Status:" + (e.getAttributes().getNamedItem("status").getNodeValue()));
map.put("tid", XMLfunctions.getValue(e, "id"));
map.put("tname", XMLfunctions.getValue(e, "name"));
map.put("tdescription", XMLfunctions.getValue(e, "description"));
mylist.add(map);
}
}
System.out.println(mylist);
}else{
Toast.makeText(ErrorCodeList.this, "No connection..", Toast.LENGTH_LONG).show();
}
return 1;
}
@Override
protected void onPostExecute(Integer result) {
setListAdapter(adapter);
progDialog.dismiss();
super.onPostExecute(result);
}
}
}
これは、hasmapをネストしようとする前のことです。これは私の目標を明確にしますか?
