Android:设置wifi后返回App

Question

在 myActivity 中，这是我用来检查我的手机是否连接到互联网的代码。

if (!isConnected()) {
            // super.playingVideo.setVideoUrl(product.getVideoUrl());
            String message = getResources().getString(R.string.wifi_prompt);
            super.showDialog(this, message, R.string.wifi_setting,
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog,
                                int which) {
                            if (dialog != null) {
                                dialog.dismiss();
                            }
                            currentProduct = product;
                            isViewRequest = true;
                            startActivity(new Intent(
                                    android.provider.Settings.ACTION_WIRELESS_SETTINGS));

                        }
                    }, R.string.back, dismissDialogListener);
        } else {...}

简历:

@Override
protected void onResume() {
    // After setting wifi
    if (isViewRequest) {
        ...//mycode
    }
    super.onResume();
}

我的问题是，当我完成 wifi 连接设置并按下后退按钮时。它返回到我手机的菜单屏幕，而不是恢复 myActivity。只有在那之后我再次启动我的应用程序时，才会执行 onResume() 函数。
那么，设置 wifi 后我想回到我的应用程序是什么？

我认为这是你的答案，你必须打开设置为 ActivityForResult :

startActivityForResult(new Intent(android.provider.Settings.ACTION_WIRELESS_SETTINGS), 0);

您可以像这样在 AlertDialog 中实现它:

AlertDialog.Builder alertDialog = new AlertDialog.Builder(
                this);

        // Setting Dialog Title
        alertDialog.setTitle("Confirm...");

        // Setting Dialog Message
        alertDialog.setMessage("Do you want to go to wifi settings?");

        // Setting Icon to Dialog
        // alertDialog.setIcon(R.drawable.ic_launcher);

        // Setting Positive "Yes" Button
        alertDialog.setPositiveButton("yes",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {

                        // Activity transfer to wifi settings
                        startActivityForResult(new Intent(android.provider.Settings.ACTION_WIRELESS_SETTINGS), 0);
                    }
                });

        // Setting Negative "NO" Button
        alertDialog.setNegativeButton("no",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        // Write your code here to invoke NO event

                        dialog.cancel();
                    }
                });

        // Showing Alert Message
        alertDialog.show();
