Android 文件读写到命名空间的文件夹（简单）

FileOutputStream fileOutputStream ;
try {
fileOutputStream = getApplicationContext().openFileOutput(
filename, MODE_WORLD_READABLE + MODE_WORLD_WRITEABLE);

fileOutputStream.write(filecontent.getBytes());
fileOutputStream.close();                                                                                                                                } catch (Exception e) {
<span style="white-space:pre">				</span>// TODO Auto-generated catch block
<span style="white-space:pre">				</span>e.printStackTrace();
<span style="white-space:pre">			</span>}

      从命名空间里的files文件夹里读取文件

String path = getApplicationContext().getFilesDir().getAbsolutePath();
filename = name.getText().toString();
path = path +"/" +filename;
File file = new File(path);
FileInputStream fileInputStream;
try {
fileInputStream = new FileInputStream(file);
byte[] buffer = new byte[1024];
fileInputStream.read(buffer);
fileInputStream.close();
String neirong = new String(buffer, "utf-8");  //内容

} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
