讀取文件

讀取文件分3步

一：創建openInput對象，參數填寫將要讀取的文件名字,使用FileInputSream接收;

二：創建BuffereReader對象，參數填寫new InputSreamReader(openFileInput對象);

三：得到BuffereReader對象reader之後，使用whil((String line = reader.readLine)!=null){

StringBuffere buffere = new StringBuffere();

buffere.append(line);

}

		FileInputStream in = null;
		BufferedReader reader = null;
		String line = "";
		StringBuffer buffere = new StringBuffer();
		try {
			in = openFileInput("name");
			reader = new BufferedReader(new InputStreamReader(in));
			while ((line = reader.readLine())!=null) {
				buffere.append(line);
			}
			Toast.makeText(MainActivity.this, buffere, 0).show();
		} catch (Exception e) {
			e.printStackTrace();
		}
