public static final String ENCODING = "GBK";
private TextView teView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
teView = (TextView) findViewById(R.id.button1);
editText2 = (EditText) findViewById(R.id.editText2);
intent_two = (Button) findViewById(R.id.intent_two);

teView.setText(getFromAssets("xieyi.txt"));

public String getFromAssets(String fileName) {
String result = "";
try {
InputStream in = getResources().getAssets().open(fileName);
// 获取文件的字节数
int lenght = in.available();
// 创建byte数组
byte[] buffer = new byte[lenght];
// 将文件中的数据读到byte数组中
in.read(buffer);
result = EncodingUtils.getString(buffer, ENCODING);
} catch (Exception e) {
e.printStackTrace();
}
return result;
