适用于Android应用程序的NativeScript中的信息亭模式 [英] Kiosk mode in NativeScript for Android App

问题描述

从过去的几天开始，我正在尝试使用Angular for Android App在NativeScript中实现信息亭模式(锁定的应用程序).

From past few days, I am trying to implement kiosk mode (Locked app) in NativeScript with Angular for Android App.

我已经直接尝试过，但是无法处理Android中的所有按钮，例如首页"和最新应用"按钮.我可以处理后退"和音量调高"按钮.

I have tried it directly but unable to handle all the buttons in Android like Home and Recent Apps buttons. I am able to handle Back and Volume up and down buttons.

我尝试过的另一种方法是使用Android Native创建我自己的插件，但无法这样做.

The other way, I tried is creating my own Plugin using Android Native but I was unable to do so.

Android Native中的Kiosk模式有两个选项.一种是屏幕固定"(以编程方式)，另一种是在Android中使用COSU(这不是我的要求，因为我无法将应用设置为1000台设备的设备所有者").

There are two options for Kiosk mode in Android Native. One is Screen Pinning (Programmatically) and the other is using COSU in Android (Which is not my requirement because I cannot set the app as Device Owner for 1000's of devices).

因此，任何人都可以分享他们在Android中使用屏幕固定以及在NativeScript中创建插件以及在NativeScript中创建示例代码的知识.

So, Can anyone share their knowledge of using Screen Pinning in Android and Creating the plugin for that in NativeScript and example Code in NativeScript.

预先感谢！

下面是我的Android Native的Java代码，用于实现屏幕固定

Below is my Java code for Android Native to implement Screen Pinning

package org.nativescript.sdoddapaneni.kioskmodeplugin;

import android.app.ActivityManager;
import android.os.Build;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class LoginActivity extends AppCompatActivity {

    private Button pinAppBtn;
    private Button unpinAppBtn;
    private ActivityManager am;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        pinAppBtn = (Button) findViewById(R.id.pin_app);
        unpinAppBtn = (Button) findViewById(R.id.unpin_app);

        am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);

        pinAppBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                pin();
            }
        });
        unpinAppBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                unpin();
            }
        });

    }

    public void unpin() {
        if (am.isInLockTaskMode()) {
            stopLockTask();
        } else {
            Toast.makeText(this, "Application already unpinned !", Toast.LENGTH_SHORT).show();
        }
    }

    public void pin() {
        startLockTask();
    }
}

推荐答案

此处是如何在NativeScript中扩展默认活动.仅供参考，对于v4.x，NativeScript仍然使用活动，它们盯着5.x引入了 AppCompatActivity ，预计将在几天后发布.

Here is how you will extend the default activity in NativeScript. FYI, With v4.x NativeScript still uses activity, staring 5.x they introduced AppCompatActivity which is expected to be released in another few days.
