android reading from a text file

So I need to load text, but I don’t know how 🙁 To save text I’m doing this

File logFile = new File("sdcard/data/agenda.file");
if (!logFile.exists())
{
    try
    {
        logFile.createNewFile();
    } 
    catch (IOException e)
    {

        e.printStackTrace();
    }
}
try
{
    //BufferedWriter for performance, true to set append to file flag
    BufferedWriter buf = new BufferedWriter(new FileWriter(logFile, true)); 
    buf.append(editText1.getText());
    buf.newLine();
    buf.close();
}
catch (IOException e)
{
    e.printStackTrace();
}

So, how to load it back by button tap?

Answer 1

To read content of file, for example *.txt – do this…

private String GetPhoneAddress() {
    File file = new File(Environment.getExternalStorageDirectory() + "/reklama/tck.txt");
    if (!file.exists()){
        String line = "Need to add smth";
        return line;
    }
    String line = null;
    //Read text from file
    //StringBuilder text = new StringBuilder();
    try {
        BufferedReader br = new BufferedReader(new FileReader(file));
        line = br.readLine(); 
        }
    catch (IOException e) {
        //You'll need to add proper error handling here
    }
    return line;
}

Then, from activite to set to textview – just do smthing like

final TextView tvphone = (TextView) findViewById(R.id.saved_phone);
    String saved_phone = GetPhoneAddress();
    if (saved_phone.length()>0){
       tvphone.setText(saved_phone);
    }
