我创建了一个列表，消息框和主要活动java文件。 当用户点击收件箱按钮时，显示您手机的所有收件箱信息。 当您选择收件箱时，会自动显示我的mainactivity.java编辑框中的内容，当您单击保存按钮时，我的应用程序中的创建文本（.txt）文件
我转发到所有xml文件，重要的是如何选择msg自动显示在编辑框上，并在应用程序中单击save create .txt文件。 当你点击保存按钮时编辑框msg创建txt文件和txt文件数据是同一编辑框msg。

答案 0 :(得分：0)
写入EditText中文件的代码
只需在保存按钮的onclick事件中调用以下方法
private void writeToFile(String data) {
try {
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(openFileOutput("config.txt", Context.MODE_PRIVATE));
outputStreamWriter.write(data);
outputStreamWriter.close();
}
catch (IOException e) {
Log.e("Exception", "File write failed: " + e.toString());
}
}
