在启动另一个Activity之前取消当前的alertDialog。调用alertDialog.dismiss（）
@Override
protected void onPostExecute(String r) {
Toast.makeText(OrderEntry.this, r, Toast.LENGTH_SHORT).show();
if (isSuccess) {
final AlertDialog.Builder alertDialogBuilder = new
AlertDialog.Builder(mContext);
alertDialogBuilder.setMessage("Would You like to Confirm
Your Order?");
alertDialogBuilder.setPositiveButton("yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int
arg1) {
try {
alertDialog.dismiss();
rs1 = stmt.executeQuery(Qr);
if (rs1.next()) {
Toast.makeText(mContext,
"hiiiiiiiiiiiiii", Toast.LENGTH_SHORT).show();
Intent i = new
Intent(OrderEntry.this, OrderRequest.class);
startActivity(i);
} else {
alertDialog.dismiss();
Toast.makeText(mContext,
"byeeeeeeeeeeeee", Toast.LENGTH_SHORT).show();
}
} catch (Exception v) {
Log.e("insert", v + "");
}
}
});
alertDialogBuilder.setNegativeButton("No", new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
alertDialog.dismiss();
isSuccess1 = false;
}
});
alertDialog = alertDialogBuilder.create();
alertDialog.setCanceledOnTouchOutside(false);
alertDialog.show();
}

您还需要发布doInBackground方法中的代码。您可以在该方法中以某种方式退出您的活动，因此尝试从＆＃34; mContext＆＃34;创建一个AlertDialog。 （无论如何，显示其余代码）会导致窗口泄漏。
这个问题可能符合您的要求：Activity has leaked window that was originally added
问题可能是您需要在更改/离开活动之前解除（）您的AlertDialog，或者您需要在创建活动之前确保活动处于活动状态。
