[Xamarin] 取得所有已安裝軟體清單 (转帖)

最近會用到，簡單記錄一下，抓取所有該手機已經安裝的軟體清單

結果圖：

首先介紹一下Layout :  \Resources\Layout\Main.axml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="vertical"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent">

    <Button

        android:id="@+id/btnGetAllList"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="取得所有APPS" />

    <ScrollView

        android:minWidth="25px"

        android:minHeight="25px"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:id="@+id/scrollView1">

        <LinearLayout

            android:orientation="vertical"

            android:minWidth="25px"

            android:minHeight="25px"

            android:layout_width="fill_parent"

            android:layout_height="wrap_content"

            android:id="@+id/linearLayout1" />

    </ScrollView>

</LinearLayout>

預覽:

按下按鈕（btnGetAllList）後 會將所有安裝過的軟體名稱放入至按鈕下方的LinearLayout（linearLayout1）中，因為怕很多所以有用ScrollViewer包起來

接下來就是 C# Code 部分：

using Android.App;

using Android.Content.PM;

using Android.Graphics;

using Android.Widget;

using Android.OS;

namespace GetAllAppList

{

    [Activity(Label = "取得所有app清單", MainLauncher = true, Icon = "@drawable/icon")]

    public class Activity1 : Activity

    {

        protected override void OnCreate(Bundle bundle)

        {

            base.OnCreate(bundle);

            // Set our view from the "main" layout resource

            SetContentView(Resource.Layout.Main);

            var btnGetAllList = FindViewById<Button>(Resource.Id.btnGetAllList);

            var appContainer = FindViewById<LinearLayout>(Resource.Id.linearLayout1);

            //取得所有APPS 按鈕事件

            btnGetAllList.Click += delegate

                {

                    var appLists = PackageManager.GetInstalledPackages(PackageInfoFlags.Activities);

                    Toast.MakeText(this, "發現已安裝數量:" + appLists.Count + "", ToastLength.Long).Show();

                    //清空容器

                    appContainer.RemoveAllViews();

                    foreach (var resolveInfo in appLists)

                    {

                        var t = new TextView(this);

                        //設定顏色 看起來比較geek

                        t.SetTextColor(new Color(0, 255, 0));

                        t.Text = resolveInfo.PackageName;

                        appContainer.AddView(t);

                    }

                };

        }

    }

}

重點在這一行：

var appLists = PackageManager.GetInstalledPackages(PackageInfoFlags.Activities);
