Question

I am using the code below to read the the txt files from my SD card, but how can I display it as Text View?

try{

               File f = new File(Environment.getExternalStorageDirectory()+"/filename.txt");
               FileInputStream fileIS = new FileInputStream(f);
               BufferedReader buf = new BufferedReader(new InputStreamReader(fileIS));
               String readString = new String();
               //just reading each line and pass it on the debugger  
               while((readString = buf.readLine())!= null){
                  Log.d("line: ", readString);

               }

            } catch (FileNotFoundException e) {

               e.printStackTrace();

            } catch (IOException e){

               e.printStackTrace();

            }

This should do it :

public void displayOutput()
{
    File sdcard = Environment.getExternalStorageDirectory();
    File file = new File(sdcard,"/TextFile.txt");
    StringBuilder text = new StringBuilder();
    try {
        BufferedReader br = new BufferedReader(new FileReader(file));
        String line;
        while ((line = br.readLine()) != null) {
            text.append(line);
            text.append('\n');
        }
    }
    catch (IOException e) {
        Toast.makeText(getApplicationContext(),"Error reading file!",Toast.LENGTH_LONG).show();
        e.printStackTrace();
    } 
    catch (FileNotFoundException e) {
        Toast.makeText(getApplicationContext(),"File not found!",Toast.LENGTH_LONG).show();
        e.printStackTrace();
    }
    TextView output=(TextView) findViewById(R.id.output); 
    // Assuming that 'output' is the id of your TextView
    output.setText(text);
}
