我正在尝试读取已保存在我的目录中的文本文件,并将其作为TextView打印在屏幕上.这是我到目前为止的代码.但是,当我运行应用程序时,它会创建一个"错误读取文件"的Toast.我在这做错了什么？
public class sub extends Activity {
private TextView text;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.text);
//text = (TextView) findViewById(R.id.summtext);
//File file = new File("inputNews.txt");
//StringBuilder text = new StringBuilder();
try {
InputStream in = openFileInput("inputNews.txt");
if(in != null){
InputStreamReader reader = new InputStreamReader(in);
BufferedReader br = new BufferedReader(reader);
StringBuilder text = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
text.append(line);
text.append('\n');
}
in.close();
}
}
catch (IOException e) {
Toast.makeText(getApplicationContext(),"Error reading file!",Toast.LENGTH_LONG).show();
e.printStackTrace();
}
TextView …
