我呼籲我的資料和baseAdapter一個活動叫Myprofile_CustomView我活動的ArrayList的Hashmap的價值，我得到它，然後我轉換成ArrayList的一個HashMap和我的問題JSON數據我該如何檢索baseadapter中hashmap的值？ 這是我的活動我的資料Android的我怎樣才能得到我的baseadapter
public class Myprofile extends Activity {
String URI_URL;
Integer page;
ProgressBar pb;
ListView mm;
Myprofile_CustomView BA;
ArrayList<HashMap<String,String>> userslist;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.myprofile);
URI_URL = getResources().getString(R.string.PathUrl) + "/api/myprofile";
page=0;
// Listview for adapter
mm= (ListView)findViewById(R.id.myprofiles);
new Myprofile_Async().execute();
}
public class Myprofile_Async extends AsyncTask<String,String,String> {
HttpURLConnection conn;
URL url;
String result="";
DataOutputStream wr;
int id;
@Override
protected void onPreExecute() {
super.onPreExecute();
pb=(ProgressBar)findViewById(R.id.progressBar);
pb.setVisibility(View.VISIBLE);
id= getIntent().getExtras().getInt("id");
// page Int is used to keep count of scroll events
if(page==0)
{page=1;}
else {page=page+1;}
Toast.makeText(Myprofile.this,""+page,Toast.LENGTH_SHORT).show();
}
@Override
protected String doInBackground(String... params) {
// Gets data from api
BufferedReader reader=null;
String cert="id="+id+"&page="+page;
try{
url = new URL(URI_URL);
conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.connect();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
wr = new DataOutputStream(conn.getOutputStream());
wr.writeBytes(cert);
wr.flush();
wr.close();
reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder sBuilder = new StringBuilder();
String line = "";
while ((line = reader.readLine()) != null) {
sBuilder.append(line + "\n");
}
result = sBuilder.toString();
reader.close();
conn.disconnect();
return result;
}
catch (Exception e)
{
e.printStackTrace();
}
System.err.println("cassies" + result);
return result;
}
@Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
try {
HashMap<String,String> map= new HashMap<>();
JSONObject jsonn= new JSONObject(result);
JSONArray jArray = jsonn.getJSONArray("myprofile");
JSONObject jobject=null;
JSONArray sss= new JSONArray();
for(int i=0; i < jArray.length(); i++) {
jobject= jArray.getJSONObject(i);
map.put("fullname",jobject.getString("fullname"));
sss.put(jobject);
}
jsonn.put("myprofile", sss);
// Add values to arrayList
userslist.add(map);
// Send information to BaseAdapter
BA= new Myprofile_CustomView(userslist,Myprofile.this);
mm.setAdapter(BA);
} catch (Exception e) {
System.err.println("mpee: " + e.toString());
}
pb.setVisibility(View.INVISIBLE);
}
}
}
這部分上面我沒有問題，我的問題是與ArrayList的用戶列表的BaseAdapter我不知道如何從它那裏得到的HashMap鍵。我命名的鑰匙，因爲我有其他領域，我最終會做
public class Myprofile_CustomView extends BaseAdapter {
JSONObject names;
Context ctx;
LayoutInflater myiflater;
ArrayList<HashMap<String,String>> usersList;
// Have data come in and do a toast to see changes
public Myprofile_CustomView(ArrayList<HashMap<String,String>> arr, Context c) {
notifyDataSetChanged();
ctx = c;
usersList= arr;
myiflater = (LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
try {
JSONArray jaLocalstreams = names.getJSONArray("myprofile");
return jaLocalstreams.length();
} catch (Exception e) {
Toast.makeText(ctx, "Error: Please try again", Toast.LENGTH_LONG).show();
return names.length();
}
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row=convertView;
MyViewHolder holder=null;
try {
if(row==null) {
LayoutInflater li = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = li.inflate(R.layout.zmyprofile,parent,false);
holder=new MyViewHolder(row);
row.setTag(holder);
}
else
{
holder=(MyViewHolder)row.getTag();
}
// How can I get HashMap value for fullname here so I can set it to to Text
String fullname= usersList
holder.fullname.setText(fullname);
return row;
} catch (Exception e) {
e.printStackTrace();
}
return row;
}
class MyViewHolder{
TextView fullname;
MyViewHolder(View v)
{
fullname= (TextView)v.findViewById(R.id.fullname);
}
}
}
