C # Xamarin Mobile development Project Combat

I. Introduction of the Course

In front of a stupid "C # Xamarin Mobile Development Basics" course, you are already familiar with and understand the fundamentals and principles of Xamarin mobile app development. This sharing lesson "C # Xamarin Mobile development Project in combat", a stupid will directly lead you into Xamarin for Android real-life Project LINK, really experience the charm of xamarin development.

Because a stupid learning Xamarin is also "halfway decent", "gig" state, video teaching about Xamarin for Android knowledge points are inevitably insufficient and imperfect place, I hope you can communicate and learn from each other. One of the promises is to share what you know as much as you can without any reservation.

This sharing course is suitable for the following groups:

1, Love Xamarin cross-platform mobile development.

2. Learn more about Xamarin for Android mobile development in real-combat knowledge.

This sharing lesson contains actual combat sharing knowledge points as follows:

1. Actual application of Android thread (UI thread)

2, Android Play assets directory of Music

3. The Xam.Plugins.Settings plugin stores application configuration information.

4, Android beautiful navigation menu bar control (Navigation bar)

5, Android Beautiful drop-down list control (ComboBox Bar)

6, Android Beautiful loading hint control (progressdialog)

7, Android Beautiful main Menu interface (GridView)

8, Android Beautiful list display data (ListView)

9. C # Xamarin App package apk file and automatic upgrade

10. Thinking and discussing mobile architecture design

1), C # How to design our Android mobile Project framework.

2), how friendly the Android logs HTTP service interface request logs.

The ultimate goal of this sharing course:

Hopefully, after this sharing session, you'll be able to quickly build a backend management app app from Xamarin for Android to turn your learning results into work.

Needless to say, directly on dry goods, we do not produce dry goods, we are just dry goods porter.

Second, the Xamarin for Android Project REAL-Combat sample Demo

Examples of project demonstrations

Third, C # Xamarin Mobile development projects to share the actual

3.1. Actual application of Android thread (UI thread)

The main thread is also called the UI thread

When a program starts, the system automatically creates a main thread, in which your app (app, WinForm, and other client programs) interacts with the UI components to handle the various events of the UI component, so the main thread is also called the UI thread.

UI component updates must be in the UI line thread

Android, for thread safety, does not allow the UI to operate on child threads outside of the UI thread, and this conclusion is not just about Android, but the concept also applies to other client systems, which have the benefit of improving the user experience and execution of the client UI.

3.2, Android Play assets directory of Music

Android The role of assets:

2: You can put some resource files

3.3. The Xam.Plugins.Settings plugin stores application configuration information.

Enter the following command on the NuGet command line.

Install-package Xam.Plugins.Settings

The main Crosssettings.current object and its 2 functions GetValueOrDefault, Addorupdatevalue, the function of these 2 functions to see the name should be very clear.

Gets the value of the specified key from the setting and converts it to the appropriate type. GetValueOrDefault (Stringkey);//Add the value of the key to the setting, or update the current value if the key already exists. Addorupdatevalue (Stringkey,tvalue);

The life cycle of the setting is the same as the application, emptied when the application is unloaded.

3.4, Android Beautiful navigation menu bar control (Navigation bar)

Android phone can be divided into navigation bar and no navigation bar two, generally have a physical button machine does not have a navigation bar, and the machine without physical keys will basically take, such as Huawei's mobile phone is basically with the navigation bar. Therefore, you need to customize the override of a navigation control.

3.5, Android Beautiful drop-down list control (ComboBox Bar)

The word spinner may be unfamiliar, in Java, the ComboBox. Because the spinner control of the Android system does not meet the requirements of the project, the custom overrides a ComboBox control.

3.6, Android beautiful loading hint control (progressdialog)

ProgressDialog can pop up a dialog box that is pinned to all interface elements in the current interface, and also has the ability to mask other controls, prompting the user to wait for the current operation to be run, and the following is the ProgressDialog use step:

1. Create an instance of ProgressDialog;

2. Set its title;

3. Set its contents;

4. Set whether you can use the back key to return, if this setting is Progressdialog.setcancelable (flase), you want to call ProgressDialog dismiss () to close the dialog box after the data load is complete;

5. Display the dialog box.

3.7, Android Beautiful main Menu interface (GridView)

3.8, Android Beautiful list display data (ListView)

3.9. C # Xamarin App package apk file and automatic upgrade

Learn more about The C # Xamarin app's package apk file and automatic upgrade course.

Three, thinking and discussion mobile architecture design

3.1. How C # Designs our Android mobile Project framework.

3.2. How to log HTTP service interface request logs with Android friendly.

Iv. Summary

It took three days for a fool to learn Xamarin to develop a prototype of the app in the video. So let's not think of how hard it is to develop Xamarin for Android, and now Microsoft is aggressively updating Xamarin, and it's only getting easier for our developers.

Learn Xamarin for Android mobile development, a goofy summed up two points:

1, have a certain C # language basic development knowledge. As long as you have a certain C # language Foundation, then getting started with Xamarin development will be without pressure.

2, master certain basic principles and knowledge of Android.

The Android interface layout and the use of common controls and the basics of Android must be mastered, and you can learn about video lessons from Java Android, because this piece of Android knowledge is the same, It doesn't have much to do with developing a language.

As the saying goes: Master led the door to practice in the individual, I hope everyone in the road of learning has been continued!
