如何修改属性的XML文件（Android Studio中）

Question

我有这样的代码：

private Properties properties; 
    private static final String myFile = "properties.xml"; 

// code for properties 
    File file = new File(getFilesDir(), myFile); 
    properties = new Properties(); 

    try{ 

     if(file.exists()){ 

      FileInputStream fish = openFileInput(myFile); 
      properties.loadFromXML(fis); 
      fis.close(); 
      Toast.makeText(this, "LOADED FROM STORAGE", Toast.LENGTH_SHORT).show(); 
     } else { 

      FileOutputStream fosa = openFileOutput(myFile, Context.MODE_PRIVATE); 
      properties.storeToXML(fos, null); 
      fos.close(); 
      Toast.makeText(this, "CREATED THE FILE", Toast.LENGTH_SHORT).show(); 
     } 

    }catch(Exception e){ 
     Log.wtf("MAIN", "error loading file"); 
    } 

而且我想进入该属性生成xml文件，但它doen't出现在Android工作室项目，有谁知道我能在哪里找到它，或者如何通过代码修改它？

这里是saveName() & menuActivity()的代码：

public void saveName(View view){ 

    properties.setProperty("name", this.editText.getText().toString()); 

    try{ 
     FileOutputStream fos = openFileOutput(myFile, Context.MODE_PRIVATE); 
     properties.storeToXML(fos, null); 
     fos.close(); 
    }catch(Exception e){ 
     Log.wtf("MAIN", "fail loading file"); 
    } 
    this.textView4.setText(properties.getProperty("name")); 
} 

public void menuActivity(View v){ 
    Intent i = new Intent(this, MenuActivity.class); 
    startActivityForResult(i, MENU_ACTIVITY_REQUEST_CODE); 
}
