Android应用程序/ Android的Studio中显示C $ C $Ç [英] Display C code inside the Android App/ Android Studio

问题描述

我目前工作的一个Android应用程序，以帮助我的同学来学习C语言的。我是pretty与应用程序的设计和布局做多，而且甚至设法把解释与例子。但我真的不知道如何显示在应用程序中的C程序。

I'm currently working on an android app to help my fellow classmates to learn C language. I'm pretty much done with the design and layout of the app, and have even managed to put explanation with example. But I really don't know how to display the C programs inside the app.

我读过有关显示HTML code和读/从原始文件夹中的文本文件显示，但我不认为这会证明是有益的在这里。另外，我是新来的Java / Android的工作室的东西，所以我要求你们都张贴有一点解释了一下详细的解答。

I've read about displaying HTML code and reading/displaying from a text file in raw folder but I don't think that'd prove helpful here. Plus I'm new to Java/Android Studio stuff so I request you all to post a bit detailed answer with little explanation.

我不一定要在C code到是颜色突出或prettified，这将是不够的，如果我能以某种方式显示出来。

I don't necessarily want the C code to be color highlighted or prettified, it would be enough if I could just somehow display it.

推荐答案

这是简单的方法来实现，这将是与存储code在一个文件中（的 http://developer.android.com/training/basics/data-storage/files.html ），并从那里读的每时间用户打开其中code可以看出的活性。

An easy way to achieve this would be with storing the code in a file ( http://developer.android.com/training/basics/data-storage/files.html ) and reading from there every time the user opens the activity where the code can be seen.

记住：

1. 权限：

1. The permissions :

<manifest ...>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
</manifest>

我建议保存在内部存储器中的文件。这样，当用户卸载应用程序，文件被删除。你可以做这样的事情阅读：

I recommend saving the files in the internal storage. This way, when the user uninstalls the app, the files are deleted. You can do something like this to read :

File dir = getFilesDir();
File file = new File(dir, "File.txt");

try {
    //Attaching BufferedReader to the FileInputStream by the help of InputStreamReader
    BufferedReader bufferedReader = new BufferedReader(new FileReader(new
            File(getFilesDir()+File.separator+"File.txt")));
    String inputString;

    s = "";
    //Reading data line by line and storing it into the stringbuffer
    while ((inputString = bufferedReader.readLine()) != null) {

        s+=inputString + "\n";

    }

    bufferedReader.close();

} catch (IOException e) {
    e.printStackTrace();
}

这写：

    try {
            FileOutputStream fos = openFileOutput("File.txt", Context.MODE_APPEND);

            for (int l = 0;l<=10;l++) {
                fos.write("something".getBytes());
                fos.write("\n".getBytes());
            }

            fos.close();

            //display file saved message

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
