Android的错误：窗口泄露的AsyncTask窗口、错误、Android、AsyncTask
我只是有时一个错误，说活动com.prueba.omnibus.EspacialTecnico渗漏最初这里
这种情况发生在活动完成和一个AsyncTask的功能被执行。我已经搜查，但我不知道什么问题可以。
I have only sometimes an error which says Activity com.prueba.omnibus.EspacialTecnico has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@41e794a0 that was originally added here
This happens when the activity finishes and an asynctask function is executed. I have searched but I have no idea what the problem could be.
操作，当用户点击完成的错误发生是DOEN。
Action that is doen when the user clicks "finish" and the error happens.
protected Dialog onCreateDialog(int id) {
super.onCreateDialog(id);
switch (id) {
case (int) DIALOG_ALERT_SALIR:
return new AlertDialog.Builder(this)
.setIcon(R.drawable.icon_warning)
.setTitle(R.string.warning)
.setMessage(R.string.confsalir)
.setPositiveButton(R.string.alert_dialog_ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton) {
if (batteryReceiver == null){
}
else{
try{
unregisterReceiver(batteryReceiver);
}catch(IllegalArgumentException iae){
}
batteryReceiver = null;
}
Correccion();
Parseo();
reloj.cancel();
if (Titulacion.IsReachable1(getApplicationContext())){
new CreateResultados().execute();
}
EspacialTecnico.this.finish();
try {
XMLResumen.escribirXMLResume();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}}
})
.setNegativeButton(R.string.alert_dialog_cancel,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton) {
}
})
.create();
}
return null;
}
AsyncTask的功能 请问错误的对话框中产生的？
Asynctask Function Could the error be produced by the dialog?
class CreateResultados extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(EspacialTecnico.this);
pDialog.setMessage("Transfiriendo...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
protected String doInBackground(String... args) {
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("id", Ident.getDNI()));
params.add(new BasicNameValuePair("nombre", Nombres.getNombre()));
params.add(new BasicNameValuePair("tablet", Nombres.Tablet()));
params.add(new BasicNameValuePair("fecha", Titulacion.fecha()));
params.add(new BasicNameValuePair("test", nombre));
params.add(new BasicNameValuePair("correctas", correctasString));
params.add(new BasicNameValuePair("errores", fallosString));
params.add(new BasicNameValuePair("PC", PC));
JSONObject json = jsonParser.makeHttpRequest(url_crear_resultados,
"POST", params);
Log.d("Create Response", json.toString());
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
} else {
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String file_url) {
pDialog.dismiss();
}
}
这有什么坏呢？感谢您的帮助
Is there anything "bad" done? Thanks for the help
推荐答案
这个异常通常来自对话框仍处于活动状态时，活动结束。
This exception usually comes from dialogs that are still active when the activity is finishing.
在在preExecute（）创建一个新的对话框，但它可能是这样 pDialog 已持有参考活性对话框。周围的一些方式：
In onPreExecute() you create a new dialog but it might be so that pDialog already holds a reference to an active dialog. Some ways around it:
创建一个新的前检查 pDialog == NULL 。驳回后分配空到 pDialog 。
如果 pDialog！= NULL ，辞退（）它首先创建一个新的对话框之前。
If pDialog != null, dismiss() it first before creating a new dialog.
（另 super.onCreateDialog（）是不必要的，因为你没有做与返回对话框东西。 ）
(Also super.onCreateDialog() is unnecessary as you're not doing anything with the returned Dialog.)
