Android从assets和raw中读取txt文件

方法一、将要读取的txt文件拷贝到Android工程目录下的assets文件夹下

方法二、在res文件夹下新建raw文件夹，将txt拷贝到该目录下

本方法是从assets中读取

/**
 * 从assets中读取txt
 */
private void readFromAssets() {
try {
InputStream is = getAssets().open("qq.txt");
String text = readTextFromSDcard(is);
textView.setText(text);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

本方法是从raw中读取

/**
 * 从raw中读取txt
 */
private void readFromRaw() {
try {
InputStream is = getResources().openRawResource(R.raw.qq);
String text = readTextFromSDcard(is);
textView.setText(text);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

本方法是解析输入流，返回txt中的字符串

/**
 * 按行读取txt
 * 
 * @param is
 * @return
 * @throws Exception
 */
private String readTextFromSDcard(InputStream is) throws Exception {
InputStreamReader reader = new InputStreamReader(is);
BufferedReader bufferedReader = new BufferedReader(reader);
StringBuffer buffer = new StringBuffer("");
String str;
while ((str = bufferedReader.readLine()) != null) {
buffer.append(str);
buffer.append("\n");
}
return buffer.toString();
}
