我与 VK Api 一起工作。我想在 ArrayList 中显示我的好友列表。我知道为此我需要解析 jsonobject 并创建一个适配器。
public class MainActivity extends Activity {
TextView text;
getFriendTask task;
ListView listView1;
VKAccessToken token;
String first_name;
String last_name;
String sex;
String bdate;
String city;
String count;
ArrayList<HashMap<String,String>> myfriend;
Friend adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
VKUIHelper.onCreate(this);
VKSdk.initialize(listener, "4571964");
VKSdk.authorize(new String[]{"friends"});
text=(TextView)findViewById(R.id.txt);
}
public void FriendClick(View view) {
if(listener!=null) {
VKRequest request = new VKRequest("friends.get", VKParameters.from(VKApiConst.FIELDS, "first_name, last_name, sex, bdate, city"));
request.start();
request.executeWithListener(new VKRequest.VKRequestListener() {
@Override
public void onComplete(VKResponse response) {
super.onComplete(response);
try{
JSONObject object=new JSONObject(response.responseString);
JSONArray array=object.getJSONArray("response");
for(int j=0; j<array.length(); j++) {
HashMap<String, String> map = new HashMap<String, String>();
object = array.getJSONObject(j);
map.put(count, object.getString("count"));
map.put(first_name, object.getString("first_name"));
map.put(last_name, object.getString("last_name"));
map.put(sex, object.getString("sex"));
map.put(bdate, object.getString("bdate"));
map.put(city, object.getString("city"));
myfriend.add(map);
}
}catch (Exception e) {
e.printStackTrace();
}
task=new getFriendTask();
task.execute();
Log.i("Are You Ready???", "Response - "+response.responseString);
}
@Override
public void onError(VKError error) {
super.onError(error);
Log.i("Are You Ready to Fly???", "EEEror - "+error.errorMessage);
}
@Override
public void attemptFailed(VKRequest request, int attemptNumber, int totalAttempts) {
super.attemptFailed(request, attemptNumber, totalAttempts);
}
});
}
}
class getFriendTask extends AsyncTask<Void,Void, Void> {
protected void onPostExecute(Void result){
super.onPostExecute(result);
listView1=(ListView)findViewById(R.id.list);
adapter=new Friend(MainActivity.this, myfriend);
}
@Override
protected Void doInBackground(Void... params) {
return null;
}
}
VKSdkListener listener=new VKSdkListener() {
@Override
public void onCaptchaError(VKError vkError) {
}
@Override
public void onTokenExpired(VKAccessToken vkAccessToken) {
}
@Override
public void onAccessDenied(VKError vkError) {
Log.d("Gooooo", " My error - "+vkError.errorMessage);
}
public void onReceiveNewToken(VKAccessToken newToken){
Log.d("Gooooo", "My token - "+newToken.accessToken);
token=newToken;
}
};
@Override
protected void onResume() {
super.onResume();
VKUIHelper.onResume(this);
}
@Override
protected void onDestroy() {
super.onDestroy();
VKUIHelper.onDestroy(this);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
VKUIHelper.onActivityResult(requestCode, resultCode, data);
}
public void onAutoClick(View view) {
}
}
还有我的适配器朋友。
class Friend extends BaseAdapter{
Context context;
LayoutInflater inflater;
HashMap<String, String> resultp=new HashMap<String, String>();
ArrayList<HashMap<String, String>> data;
public Friend(Context context, ArrayList<HashMap<String, String>> myfriend){
this.context=context;
data=myfriend; }
@Override
public int getCount() {
return data.size();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView fname;
TextView lname;
TextView sx;
TextView bd;
TextView ct;
inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView=inflater.inflate(R.layout.friendlist, parent, false);
resultp=data.get(position);
fname=(TextView)itemView.findViewById(R.id.fname);
lname=(TextView)itemView.findViewById(R.id.lname);
sx=(TextView)itemView.findViewById(R.id.sx);
bd=(TextView)itemView.findViewById(R.id.bd);
ct=(TextView)itemView.findViewById(R.id.ct);
return itemView;
}}
但 Android Studio 给出了与 JSONArray 一致的错误。我不明白这段代码有什么问题？？？
