从Android手机的内部存储器写入/读取文件

Question

我有一个名为'MyClass'的实用程序类。这个类有两种方法来读/写一些数据到手机的内存中。我是android新手，请按照以下代码进行操作。

public class MyClass { 
    public void ConfWrite() { 
    try { 
     BufferedWriter bufferedWriter = new BufferedWriter(new FileWriter(new 
          File(getFilesDir()+File.separator+"MyFile.txt"))); 
     bufferedWriter.write("lalit poptani"); 
     bufferedWriter.close(); 
    } catch (Exception e1) { 
     e1.printStackTrace(); 
    } 
    } 
} 

在执行ConfWrite方法，它失败

请提供更好的解决方案提前

解决这个

感谢您能Read/ Write您在data/data/package_name/files文件夹文件通过，

要写

BufferedWriter bufferedWriter = new BufferedWriter(new FileWriter(new 
          File(getFilesDir()+File.separator+"MyFile.txt"))); 
bufferedWriter.write("lalit poptani"); 
bufferedWriter.close(); 

来读取

BufferedReader bufferedReader = new BufferedReader(new FileReader(new 
          File(getFilesDir()+File.separator+"MyFile.txt"))); 
String read; 
StringBuilder builder = new StringBuilder(""); 

while((read = bufferedReader.readLine()) != null){ 
     builder.append(read); 
     } 
Log.d("Output", builder.toString()); 
bufferedReader.close();
