How do I access a data path?

问题

我已经获得了关于数据路径的所有信息,因为它在另一个问题中已经回答了。我的问题是,我是非常非常新手,不明白我应该在哪里输入文本才能真正获取信息。

这是文本:

private String getFilePath(){
    ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
    File filePath = contextWrapper.getFilesDir();
    File file = new File(filePath, "fileName" + "/*/");
    return file.getPath();
}
  • 显然,使用我的文件名,我从logcat中获取 -

我应该在哪里输入以访问信息?就像我说的,我很新,如果有人能为我“降低难度”我会非常感激。

可能有用的其他信息:

  • 我使用的是三星Galaxy a12
  • 设备未root

我还没有真正尝试过任何方法。

英文:

So I have all the information I need regarding the data path because it was answered in another question. My problem is that I’m very very new and I don’t understand where I’m supposed to enter the text in order to actually get to the information.

This is the text:

private String getFilePath(){
    ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
    File filePath = contextWrapper.getFilesDir();
    File file = new File(filePath,"fileName" +"*/*");
    return file.getPath();
}

  • obviously with my own file name, which I got from logcat -

Where do I input that in order to access the information? Like I said, I’m very new and would appreciate if anyone could “dumb it down” for me.

Additional information that may or not be useful:

  • I’m using a Samsung Galaxy a12
  • Device is not rooted

I haven’t really tried anything yet.

要使用提供的代码访问数据路径,请按照以下步骤操作:

  1. 在集成开发环境(IDE)中,如Android Studio中打开您的Android项目。
  2. 找到您想要访问数据路径的类。通常,这是一个扩展名为".java"的Java文件。
  3. 在该类内部,您需要添加一个包含提供的代码片段的方法。以下是一个示例:
public class YourClass extends AppCompatActivity {

    // ... 您现有的代码 ...

    private String getFilePath(){
        ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
        File filePath = contextWrapper.getFilesDir();
        File file = new File(filePath, "fileName");
        return file.getPath();
    }

    // ... 您现有的代码 ...
}

在上面的代码中,请确保将"fileName"替换为您从Logcat获得的实际文件名称。
4. 一旦将此方法添加到您的类中,您可以从另一个方法或需要访问数据路径的任何地方调用它。例如,您可以从onCreate()方法中调用它:

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

    String dataPath = getFilePath();
    // 现在,您可以使用'dataPath'变量访问数据路径。
    // 例如,您可以在TextView中显示它或将其用于文件操作。
}

将"your_layout"替换为您为活动使用的实际布局文件名称。
5. 在执行了这些步骤并在Samsung Galaxy A12上运行应用程序之后,应该会调用getFilePath()方法,并且它将返回数据路径。然后,您可以使用返回的路径访问所需的信息或执行任何必要的文件操作。

英文:

To access the data path using the provided code, you need to follow these steps:

Open your Android project in an Integrated Development Environment (IDE) such as Android Studio.
Locate the class where you want to access the data path. It's usually a Java file with the extension ".java".
Within that class, you need to add a method that includes the provided code snippet. Here's an example:

  public class YourClass extends AppCompatActivity {

    // ... your existing code ...

    private String getFilePath(){
        ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
        File filePath = contextWrapper.getFilesDir();
        File file = new File(filePath,"fileName");
        return file.getPath();
    }

    // ... your existing code ...
}

In the above code, make sure you replace "fileName" with the actual name of the file you obtained from Logcat.
Once you have added this method to your class, you can call it from another method or wherever you need to access the data path. For example, you can call it from the onCreate() method:

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

    String dataPath = getFilePath();
    // Now you can use the 'dataPath' variable to access the data path.
    // For example, you can display it in a TextView or use it for file operations.
}

Replace "your_layout" with the actual layout file name you are using for your activity.
After performing these steps and running your app on your Samsung Galaxy A12, the getFilePath() method should be called, and it will return the data path. You can then use the returned path to access the desired information or perform any necessary file operations.
