我有一个BaseAdapter，我有一个Button。当用户单击该按钮时，我需要调用 aService并且需要将数据设置为该按钮onpostExecute()
public class MenuTagsAdapter extends BaseAdapter {
View v;
@Override
public int getCount() {
// TODO Auto-generated method stub
return BaseApp.getTagsAroundMeList().size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = layoutInflater.inflate(R.layout.menutaglistitem, null);
TextView textViewName = (TextView) v
.findViewById(R.id.textViewName);
final Button buttonAction = (Button) v
.findViewById(R.id.buttonAction);
textViewName.setText("#"
+ BaseApp.getTagsAroundMeList().get(position).name);
buttonAction
.setText(BaseApp.getTagsAroundMeList().get(position).action);
buttonAction.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (buttonAction.getText().toString()
.equalsIgnoreCase("follow")) {
buttonAction.setBackgroundResource(R.drawable.followbutton);
if (appUtils.getNetworkInfo(AmgonnaHome.this)) {
new FollowInterestAsyTask().execute();
} else {
NetworkDialogClass.createDAlertDialog(
AmgonnaHome.this,
getString(R.string.network_error));
}
} else {
buttonAction.setBackgroundResource(R.drawable.unfollowbutton);
if (appUtils.getNetworkInfo(AmgonnaHome.this)) {
new UnfollowInterestAsyTask().execute();
} else {
NetworkDialogClass.createDAlertDialog(
AmgonnaHome.this,
getString(R.string.network_error));
}
}
}
});
return v;
}
}
public class FollowInterestAsyTask extends AsyncTask<Void, Void, Void> {
boolean progressDialogStatus = true;
@Override
protected void onPreExecute() {
progressDialog = ProgressDialog.show(AmgonnaHome.this,
"Please Wait", "Connecting to Server");
progressDialog.setOnCancelListener(new OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
progressDialogStatus = false;
}
});
}
@Override
protected Void doInBackground(Void... params) {
TaskUrl = BaseApp.baseUrl + BaseApp.followInterest;
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("user_id=" + amgonnaUserId);
// stringBuilder.append("&interestName="+);
stringBuilder.append("&interestName=");
ConnectionManager connectionManager = new ConnectionManager();
String response = connectionManager.setUpHttpPost(TaskUrl,
stringBuilder.toString());
if (response != null) {
try {
JSONObject jsonObject = new JSONObject(response);
errStatus = jsonObject.getInt("errStatus");
status = jsonObject.getString("status");
} catch (Exception e) {
// TODO: handle exception
}
}
return null;
}
@Override
protected void onPostExecute(Void result) {
if (progressDialogStatus) {
progressDialog.dismiss();
if (errStatus == 0) {
// here i need to set the status message to button on adapter list item
}
}
}
}
