Question

当我使用

时

protected void onPostExecute(String result) {

        if (result.contentEquals("Success")) {
            if(tellAFriend.message.contentEquals("Success")){
                showAlert(TellAFriend.this, getResources().getString(R.string.tell_friend_alert), "1");

    //After showing alertbox clicking ok it has to go to myclass instead of homescreen

            } else if(tellAFriend.message.contentEquals("Failure")){
                if ((language.contentEquals("")) || (language.contentEquals("en"))) {
                    showAlert(TellAFriend.this, Contact.Reason_Eng,"3");
                } else if(language.contentEquals("ar")){
                    showAlert(TellAFriend.this, Contact.Reason_Ar,"3");
                }
            }

        } else {
            showAlert(TellAFriend.this, "Response Failure", "1");
        }

        Dialog.dismiss();

    }




public void showAlert(final Context context, String message,
        final String type) {

    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
            context);

    // set title
    alertDialogBuilder
            .setTitle(getResources().getString(R.string.app_name));
    language = sharedPreference.getString("language", "");
    if ((language.contentEquals("")) || (language.contentEquals("en"))) {
        alertDialogBuilder
                .setMessage(message)
                .setCancelable(false)
                .setNeutralButton("OK",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int id) {
                                if (type.contentEquals("1")) {
                                    finish();
                                    Intent mainwin = new Intent(context,
                                            MainWindow.class);
                                    startActivity(mainwin);
                                } else if (type.contentEquals("2")) {
                                    finish();
                                    Intent intentList = new Intent(context,
                                            OilTrackerListView.class);
                                    startActivity(intentList);
                                } else if (type.contentEquals("3")) {
                                    dialog.dismiss();
                                }
                                dialog.dismiss();

                            }
                        });

    } else if (language.contains("ar")) {
        alertDialogBuilder
                .setMessage(message)
                .setCancelable(false)
                .setNeutralButton(getResources().getString(R.string.ok),
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int id) {
                                if (type.contentEquals("1")) {
                                    finish();
                                    Intent mainwin = new Intent(context,
                                            MainWindow.class);
                                    startActivity(mainwin);
                                } else if (type.contentEquals("2")) {
                                    finish();
                                    Intent intentList = new Intent(context,
                                            OilTrackerListView.class);
                                    startActivity(intentList);
                                } else if (type.contentEquals("3")) {
                                    dialog.dismiss();
                                }
                                dialog.dismiss();

                            }
                        });

    }

    AlertDialog alertDialog = alertDialogBuilder.create();

    // show it
    alertDialog.show();
}

警报框打开，当我点击确定时屏幕进入主屏幕。我需要打开另一个类而不是homescreen.i无法找到showalert.Just现在发现。我认为这是一个已定义的功能在android。

Answer 1

AlertDialog中的OK按钮的监听器必须是这样的。我认为您正在呼叫finish() in onClick()

        alert.setButton(DialogInterface.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {

            alert.dismiss();    

        }
        });

我想我必须在这里改变

if (type.contentEquals("1")) {
                                finish();
                                Intent mainwin = new Intent(context,
                                        whichclassiwant.class);
                                startActivity(mainwin);
                            }

当我在对话框后使用show alert进入主屏幕时？如何阻止它？
