/Lib/NavigationSam.Droid/Resources/AboutResources.txt:
--------------------------------------------------------------------------------
1 | Images, layout descriptions, binary blobs and string dictionaries can be included
2 | in your application as resource files. Various Android APIs are designed to
3 | operate on the resource IDs instead of dealing with images, strings or binary blobs
4 | directly.
5 |
6 | For example, a sample Android app that contains a user interface layout (main.xml),
7 | an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png)
8 | would keep its resources in the "Resources" directory of the application:
9 |
10 | Resources/
11 | drawable/
12 | icon.png
13 |
14 | layout/
15 | main.xml
16 |
17 | values/
18 | strings.xml
19 |
20 | In order to get the build system to recognize Android resources, set the build action to
21 | "AndroidResource". The native Android APIs do not operate directly with filenames, but
22 | instead operate on resource IDs. When you compile an Android application that uses resources,
23 | the build system will package the resources for distribution and generate a class called "R"
24 | (this is an Android convention) that contains the tokens for each one of the resources
25 | included. For example, for the above Resources layout, this is what the R class would expose:
26 |
27 | public class R {
28 | public class drawable {
29 | public const int icon = 0x123;
30 | }
31 |
32 | public class layout {
33 | public const int main = 0x456;
34 | }
35 |
36 | public class strings {
37 | public const int first_string = 0xabc;
38 | public const int second_string = 0xbcd;
39 | }
40 | }
41 |
42 | You would then use R.drawable.icon to reference the drawable/icon.png file, or R.layout.main
43 | to reference the layout/main.xml file, or R.strings.first_string to reference the first
44 | string in the dictionary file values/strings.xml.

24 | ## Supported Platforms
25 | - Android
26 | - iOS
27 | - UWP not support (use native method OnBackButtonPressed, see example)
28 |
29 |
30 | ## Install android project
31 | ```c#
32 | // Pay attention to the inherited class!!! FormsAppCompatActivitySam
33 | public class MainActivity : global::NavigationSam.Droid.FormsAppCompatActivitySam
34 | {
35 | protected override void OnCreate(Bundle savedInstanceState)
36 | {
37 | TabLayoutResource = Resource.Layout.Tabbar;
38 | ToolbarResource = Resource.Layout.Toolbar;
39 |
40 | base.OnCreate(savedInstanceState);
41 |
42 | NavigationSam.Droid.Preserver.Preserve();
43 | Xamarin.Forms.Forms.Init(this, savedInstanceState);
44 | LoadApplication(new App());
45 | }
46 | }
47 | ```
48 |
49 | ## Install iOS project
50 | ```c#
51 | public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
52 | {
53 | public override bool FinishedLaunching(UIApplication app, NSDictionary options)
54 | {
55 | global::Xamarin.Forms.Forms.Init();
56 | LoadApplication(new App());
57 |
58 | NavigationSam.iOS.Preserver.Preserve();
59 |
60 | return base.FinishedLaunching(app, options);
61 | }
62 | }
63 | ```
64 |
65 | # Example
66 | For Xamarin.Forms entry point
67 | ```c#
68 | public partial class App : Application
69 | {
70 | InitializeComponent();
71 | MainPage = new NavigationPageSam(new MainPage());
72 | }
73 | ```
74 | For pages
75 | ```c#
76 | public partial class SamplePage : ContentPage, INavigationPopInterceptor
77 | {
78 | public SamplePage()
79 | {
80 | InitializeComponent();
81 | }
82 |
83 | // Important service property
84 | public bool IsPopRequest { get; set; }
85 |
86 | public async Task RequestPop()
87 | {
88 | bool res = true;
89 |
90 | if (CheckChanges())
91 | res = await DisplayAlert("Warning",
92 | "If you exit, all unsaved changes will be lost",
93 | "Exit", "Cancel");
94 |
95 | return res;
96 | }
97 |
98 | // For UWP
99 | protected override bool OnBackButtonPressed()
100 | {
101 | Device.BeginInvokeOnMainThread(async () =>
102 | {
103 | bool res = await RequestPop();
104 | if (res)
105 | await Navigation.PopAsync();
106 | });
107 | return true;
108 | }
109 | }
110 | ```
111 |
112 | # Example MVVM
113 | Same as above.
114 | INavigationPopInterceptor can implement to ViewModel
115 |
116 | Warning: for UWP need realization method OnBackButtonPressed for Page. For detail see Sample project
117 | ```c#
118 | public class SampleVm : BaseViewModel, INavigationPopInterceptor
119 | {
120 | public SampleVm()
121 | {
122 | //Do something...
123 | }
124 |
125 | // Important service property
126 | public bool IsPopRequest { get; set; }
127 |
128 | public async Task RequestPop()
129 | {
130 | bool res = true;
131 |
132 | if (CheckChanges())
133 | res = await Page.DisplayAlert("Warning",
134 | "If you exit, all unsaved changes will be lost",
135 | "Exit", "Cancel");
136 |
137 | return res;
138 | }
139 | }

1 | Any raw assets you want to be deployed with your application can be placed in
2 | this directory (and child directories) and given a Build Action of "AndroidAsset".
3 |
4 | These files will be deployed with your package and will be accessible using Android's
5 | AssetManager, like this:
6 |
7 | public class ReadAsset : Activity
8 | {
9 | protected override void OnCreate (Bundle bundle)
10 | {
11 | base.OnCreate (bundle);
12 |
13 | InputStream input = Assets.Open ("my_asset.txt");
14 | }
15 | }
16 |
17 | Additionally, some Android functions will automatically load asset files:
18 |
19 | Typeface tf = Typeface.CreateFromAsset (Context.Assets, "fonts/samplefont.ttf");

/Sample/Sample.Android/Resources/AboutResources.txt:
--------------------------------------------------------------------------------
1 | Images, layout descriptions, binary blobs and string dictionaries can be included
2 | in your application as resource files. Various Android APIs are designed to
3 | operate on the resource IDs instead of dealing with images, strings or binary blobs
4 | directly.
5 |
6 | For example, a sample Android app that contains a user interface layout (main.xml),
7 | an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png)
8 | would keep its resources in the "Resources" directory of the application:
9 |
10 | Resources/
11 | drawable-hdpi/
12 | icon.png
13 |
14 | drawable-ldpi/
15 | icon.png
16 |
17 | drawable-mdpi/
18 | icon.png
19 |
20 | layout/
21 | main.xml
22 |
23 | values/
24 | strings.xml
25 |
26 | In order to get the build system to recognize Android resources, set the build action to
27 | "AndroidResource". The native Android APIs do not operate directly with filenames, but
28 | instead operate on resource IDs. When you compile an Android application that uses resources,
29 | the build system will package the resources for distribution and generate a class called
30 | "Resource" that contains the tokens for each one of the resources included. For example,
31 | for the above Resources layout, this is what the Resource class would expose:
32 |
33 | public class Resource {
34 | public class drawable {
35 | public const int icon = 0x123;
36 | }
37 |
38 | public class layout {
39 | public const int main = 0x456;
40 | }
41 |
42 | public class strings {
43 | public const int first_string = 0xabc;
44 | public const int second_string = 0xbcd;
45 | }
46 | }
47 |
48 | You would then use R.drawable.icon to reference the drawable/icon.png file, or Resource.layout.main
49 | to reference the layout/main.xml file, or Resource.strings.first_string to reference the first
50 | string in the dictionary file values/strings.xml.
