[英]read a text file android
I am trying to make the computer read a text file full of words and add it to an ArrayList. 我试图使计算机读取一个充满单词的文本文件,并将其添加到ArrayList中。 I made it work on a regular Java application, but can't get it to work on Android.
我使它可以在常规Java应用程序上运行,但无法使其在Android上运行。 Can someone help me out?
有人可以帮我吗?
try {
FileInputStream textfl = (FileInputStream) getAssets().open("test.txt");
DataInputStream is = new DataInputStream(textfl);
BufferedReader r = new BufferedReader(new InputStreamReader(is));
String strLine;
while ((strLine = r.readLine()) != null) {
tots.add(strLine); //tots is the array list
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I keep getting a error. 我不断收到错误消息。 The text file is 587kb, so could that be a problem?
文本文件为587kb,所以这可能是个问题吗?
try this. 尝试这个。
private static String readTextFile(String fileName)
{
BufferedReader in = null;
try
{
in = new BufferedReader(new InputStreamReader(getAssets().open(fileName)));
String line;
final StringBuilder buffer = new StringBuilder();
while ((line = in.readLine()) != null)
{
buffer.append(line).append(System.getProperty("line.separator"));
}
return buffer.toString();
}
catch (final IOException e)
{
return "";
}
finally
{
try
{
in.close();
}
catch (IOException e)
{
// ignore //
}
}
}
