Question

您好，我无法使用FileInputStream读取文件内容。我使用的代码如下：

    List<ContentValues> poisList = new ArrayList<ContentValues>();
    try {
        FileInputStream fis = new FileInputStream (new File(filePath));
        BufferedReader br = new BufferedReader(new InputStreamReader(fis));
        String line = "";

        while ((line = br.readLine()) != null) {
            viewHolder.logout.setText(line);
            readPOI(poisList, line, categoryID);
        }
        br.close();

    } catch (FileNotFoundException e) {
        e.printStackTrace();
        Toast.makeText(getActivity(), "File", Toast.LENGTH_LONG).show();
    } catch (IOException e) {
        e.printStackTrace();
        Toast.makeText(getActivity(), "IO", Toast.LENGTH_LONG).show();
    }

变量 filePath 的值为：＆＃34; / document / primary：Download / Taiwan.txt＆＃34;。我通过使用Intent.ACTION_GET_CONTENT和使用后得到它：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == 1){
        if(resultCode == Activity.RESULT_OK){
            filePath = data.getData().getPath();

我还使用了以下两个选项来获取文件，但也没有工作：

        FileInputStream fis = getActivity().openFileInput(filePath);
          InputStream is = getClass().getResourceAsStream(filePath);

错误是这样的：
