android 读取资源文件的数据

1，读取assets文件夹中的数据：

try {
InputStream is = getResources().getAssets().open("info.txt");
InputStreamReader reader = new InputStreamReader(is, "UTF-8");
BufferedReader bufferedReader = new BufferedReader(reader);
String line = "";
while ((line=bufferedReader.readLine())!=null)
Log.d("===", "readLine:"+line);
} catch (IOException e) {
e.printStackTrace();
}

2，读取raw文件夹中的数据：

InputStream is = getResources().openRawResource(R.raw.info);
InputStreamReader reader = null;
try {
reader = new InputStreamReader(is, "UTF-8");
BufferedReader bufferedReader = new BufferedReader(reader);
String line = "";
while ((line=bufferedReader.readLine())!=null){
Log.d("===", "readLine:"+line);
}
}catch (IOException e) {
e.printStackTrace();
}

3，写内部存储的文件数据（文件保存在data/data/包名/file 下）

try {
FileOutputStream fos = openFileOutput(fileName, MODE_PRIVATE);
OutputStreamWriter osw = new OutputStreamWriter(fos, "UTF-8");
osw.write(数据);
osw.flush();
fos.flush();
osw.close();
fos.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

4，读内部存储的文件数据（文件路径：data/data/包名/file 下）

try {
FileInputStream fis = openFileInput(fileName);
InputStreamReader isr = new InputStreamReader(fis, "UTF-8");
char[] input = new char[fis.available()];
isr.read(input);
isr.close();
fis.close();
String result = new String(input);

} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
