Question

我正在尝试创建一个Android应用程序，在其中它将获取资产中的文件内容，将内容复制到filestorage中的文件。然后在显示时，它将读取filestorage中的文件，并在edittext中追加这些行。我面临的问题是没有读取空行。

以下是我正在阅读资产文件内容并将其复制到文件“current.txt”中的代码片段，该文件将存储在filestorage中。

以下是我在其中添加“current.txt”文件内容的edittext的代码段

reader = new BufferedReader(new              InputStreamReader(getAssets().open("pravachan.txt")));


   ContextWrapper contextWrapper=new    ContextWrapper(getApplicationContext());
    File directory= contextWrapper.getDir("FileStorage",Context.MODE_PRIVATE);
                File myInternalFile=new File(directory,"current.txt");

                FileWriter filewriter = new FileWriter(myInternalFile);
                   BufferedWriter out = new BufferedWriter(filewriter);


                String mLine = reader.readLine();

                    while (mLine != null)
                    {
                        //process line
                        if(mLine.isEmpty())
                        {
                            out.write(" ");
                            String str = System.getProperty("line.separator");
                            out.write(str);
                        }

                        else
                            out.write(mLine);


                        mLine = reader.readLine();


                    }
                    out.close();

我不希望跳过空行。我希望文件在Edittext中显示。请帮忙。提前谢谢！

Answer 1

我得到了答案！我没有做out.write（str），其中str是行分隔符，而是out.newline（）。它奏效了！

如何在从文件中读取文本时在EditText字段中插入新行
