当我点击列表值意味着该网址已被点击,当时我想退出此活动并返回去?
答案 0 :(得分:0)
尝试这种方式..根据我的建议,尝试在doInBackground()中使用Asynctask执行所有Web服务代码,并在onPostExecute()中执行剩余的过程,如下所示,
// onItemclick()
new GetTask().execute();
// GetTask Class
public class GetTask extends AsyncTask<Object, Void, String> {
ProgressDialog progdialog;
@Override
protected void onPreExecute() {
super.onPreExecute();
progdialog = ProgressDialog.show(context, null,
"loading..");
}
@Override
protected String doInBackground(Object... params) {
//webservice
return null;
}
@Override
protected void onPostExecute(String result) {
progdialog.dismiss();
// finish the activity..
// if you start this activity without finishing then call as
finish();
// if not
Intent in=new Intent(currentclass.this,nextactivity.class);
startActivity(in);
finish();
super.onPostExecute(result);
}
}
alertdialog:
new AlertDialog.Builder(AccountListActivity.this)
.setTitle("Title")
.setMessage(message))
.setPositiveButton(ok), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,int which) {
Intent in = new Intent(currentClass.this,nextactivity.class);
startActivity(in);
}
}).show();
