从Assets读取文件 用scanner扫描inputstream

代码如下：

对InputStream的处理，从assets获取数据

InputStream in;
try {
in = getAssets().open("Android05.txt");
Scanner input=new Scanner(in);
StringBuilder builder=new StringBuilder();
while (input.hasNext()) {
builder.append(input.nextLine()+"\n");
}
tView.setText(builder);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
