viewing a txt file from a textview - java

i want to show a txt file by a text view and i use of this code
TextView helpText = (TextView) findViewById(R.id.TextView_HelpText);
InputStream iFile = getResources().openRawResource(R.raw.quizhelp);
String strFile = inputStreamToString(iFile);
helpText.setText(strFile);
in api 8 i have tested and this code works fine but in my new project that i have setted min sdk to 15 , can NOT recognize inputStreamToString method ! what method i should use instead this ?
tnx

You can use BufferedReader:
TextView helpText = (TextView) findViewById(R.id.TextView_HelpText);
InputStream iFile = getResources().openRawResource(R.raw.quizhelp);
BufferedReader bufferReader = new BufferedReader(new InputStreamReader(iFile));
StringBuilder sb = new StringBuilder();
String newline = System.getProperty("line.separator");
String line;
try {
while ((line = bufferReader.readLine()) != null) {
sb.append(line);
sb.append(newline);
}
} catch (IOException e) {
e.printStackTrace();
}
helpText.setText(sb.toString());

You can do it this way
TextView helpText = (TextView) findViewById(R.id.TextView_HelpText);
try {
Resources res = getResources();
InputStream ins = res.openRawResource(R.raw.quizhelp);
byte[] b = new byte[ins.available()];
ins.read(b);
helpText.setText(new String(b));
} catch (Exception e) {
e.printStackTrace();
}

Data management from file in Android

I am not able to save data from file into an object.If I recover the data from the file and save them in a string, the application works, but as soon as I try to save them inside an object (a Note object in my case), I fail .
It is a simple app(similar to notepads) with only a mainActivity to manage operations, an object class that include two variable, one for "title" and another one for "text" and an xml file with two input fields, two buttons(load and save) and a textView to view the data.
This is the the mainActivity code:
public class MainActivity extends AppCompatActivity {
EditText title,text;
Button save,load;
TextView result;
ArrayList<Note> notes = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
title = findViewById(R.id.id_title);
text = findViewById((R.id.id_post));
save = findViewById(R.id.buttonSave);
load = findViewById(R.id.buttonLoad);
result = findViewById(R.id.id_result);
Context context = getApplicationContext();
save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String titolo = title.getText().toString();
String post = text.getText().toString();
//Note nota = new Note(titolo,post);
Note nota = new Note(titolo,post);
//nota.setTitle(titolo);
//nota.setNote(post);
saveData(nota,context);
}
});
load.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//ArrayList<Note> data;
//String x;
//x= readData(context);
//x = data.getTitle() + " " +data.getNote();
//result.setText(x);
//setTextToTextview();
readData(context);
}
});
}
/**

* #param nota
* #param context
*/
public void saveData(Note nota,Context context) {
try {
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(context.openFileOutput("text.txt", Context.MODE_APPEND));
outputStreamWriter.write(nota.getTitle().toString() + "," + nota.getNote().toString() + "\n");
outputStreamWriter.flush();
outputStreamWriter.close();
Toast.makeText(MainActivity.this, "Saved", Toast.LENGTH_SHORT).show();
}
catch (IOException e)
{
e.getMessage();
}
}
private void setTextToTextview() {
String text = "";
for(int i = 0; i < notes.size(); i++)
{
text = text + notes.get(i).getTitle() + "" + notes.get(i).getNote() + "\n";
}
result.setText(text);
}

AndroidStudio - save user info in CSV file and read it

I'm a newbie in programming on Android Studio. I'm trying to create a simple application to gain basic experience. In the application, I would need to store individual inputs to a file (ideally CSV) in internal memory. First of all, I am trying to save user data - my name and phone number. The save method looks like this:
public void save(View view)
{
String fileName = "user.csv";
ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
File directory = contextWrapper.getDir(getFilesDir().getName(), ContextWrapper.MODE_PRIVATE);
File file = new File(directory, fileName);
String data = "FirstName,LastName,PhoneNumber";
FileOutputStream outputStream;
try {
outputStream = openFileOutput(fileName, Context.MODE_PRIVATE);
outputStream.write(data.getBytes());
outputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
}
The data seems to be saved and I'm redirected to MainActivity. Here is the method:
protected void onCreate(Bundle savedInstanceState) {
File file = new File(getFilesDir(),"user.csv");
if(!file.exists()) {
Intent intent = new Intent(this, activity_login.class);
startActivity(intent);
}
else {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView tv_name = findViewById(R.id.tv_name);
TextView tv_phone = findViewById(R.id.tv_phone);
BufferedReader br = null;
try {
String sCurrentLine;
br = new BufferedReader(new FileReader("user.csv"));
while ((sCurrentLine = br.readLine()) != null) {
tv_name.setText(sCurrentLine);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (br != null)br.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
}
No value is stored in TextView tv_name and the box is empty. Where am I making mistake?
Thank you very much for your help!
For reading data saved use this method uses, UTF_8 ENCODING
public static String readAsString(InputStream is) throws IOException {
BufferedReader reader = null;
StringBuilder sb = new StringBuilder();
try {
String line;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
reader = new BufferedReader(new InputStreamReader(is,UTF_8));
}
while ((line = reader.readLine()) != null) {
sb.append(line);
}
} finally {
if (reader != null) {
reader.close();
}
}
return sb.toString();
}
Use this method as follows, parsing file "user.csv".
public static String readFileAsString(File file) throws IOException {
return readAsString(new FileInputStream(file));
}
Fetch string and set textView
Use as this to read file:
FileInputStream fis = new FileInputStream("your full file path");
BufferedReader bfr = new BufferedReader(new InputStreamReader(fis));
Below is the code for creating .csv file and inserting data into it.
For more look into my answer :https://stackoverflow.com/a/48643905/8448886
CODE HERE:
String csv = (Environment.getExternalStorageDirectory().getAbsolutePath() + "/MyCsvFile.csv"); // Here csv file name is MyCsvFile.csv
//by Hiting button csv will create inside phone storage.
buttonAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
CSVWriter writer = null;
try {
writer = new CSVWriter(new FileWriter(csv));
List<String[]> data = new ArrayList<String[]>();
data.add(new String[]{"Country", "Capital"});
data.add(new String[]{"India", "New Delhi"});
data.add(new String[]{"United States", "Washington D.C"});
data.add(new String[]{"Germany", "Berlin"});
writer.writeAll(data); // data is adding to csv
writer.close();
callRead();
} catch (IOException e) {
e.printStackTrace();
}
}
});

display file content line by line in textview

I have this code below: I want to view every line by line in textview but there is a problem,
public class Resulat2 extends Activity {
private Handler h = new Handler();
private Handler mHandler = new Handler();
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.newee);
try {
File file2 = new File(Ppp.path);
FileReader fileReader = new FileReader(file2);
BufferedReader bufferedReader = new BufferedReader(fileReader);
String line;
final ScrollView scrollview = (ScrollView) findViewById(R.id.scrollView);
final TextView textview = (TextView) findViewById(R.id.textView10);
final StringBuilder sb = new StringBuilder("");
while ((line = bufferedReader.readLine()) != null){
final String finalLine = line;
new Thread(new Runnable() {
public void run() {
sb.append(finalLine);
sb.append("\n");
Log.d("testing5", finalLine);
}
}).start();
Thread.sleep(1000);
}
runOnUiThread(new Runnable() {
public void run() {
textview.setText(sb.toString());
textview.setMovementMethod(new ScrollingMovementMethod());
scrollview.post(new Runnable() {
#Override
public void run() {
scrollview.fullScroll(ScrollView.FOCUS_DOWN);
}
});
}
});
fileReader.close();
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
When I run, the log.d works perfectly but the textview is not shown.
your update for the textview has a minor flaw, it runs only once and then stops...
a simple solution might be introducing a boolean or (even more simply) check if your 'line' not is null...
runOnUiThread(new Runnable() {
public void run() {
while(line!= null){
textview.setText(sb.toString());
//...
Thread.sleep(200) //let other processes have some cpu
}
});
}
});
don't forget to make your String line a member of your class, so that your Runnable has access to it...
private String line = null;
Try this..it might help
File sdcard = Environment.getExternalStorageDirectory();
//Get the text file
File file = new File(sdcard,"file.txt");
//Read text from file
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');
}
br.close();
}
catch (IOException e) {
//You'll need to add proper error handling here
}
//Find the view by its id
TextView tv = (TextView)findViewById(R.id.text_view);
//Set the text
tv.setText(text);

Can Anyone please help? Thank you and appreciated!
There are various issues with your code, but the cause of the particular exception is explained right there in Logcat:
Only the original thread that created a view hierarchy can touch its views.
The line in question is com.example.descracker.Homepage:245 where you invoke setText() on a TextView from an AsyncTask. You will have to move this logic into the UI thread, for instance through AsyncTask's facility functions onPreExecute(), onPostExecute() or onProgressUpdate(), or by posting a delayed action to the view itself using post(Runnable).
Also, please follow Java coding conventions and start your variables names with a lowercase letter.
As Shashank kadhe mentioned try this in your onPostExecute method and please change it according to your own need.
protected void onPostExecute(String file_url) {

how to print a string in a textview?

I am new to all of this android programming. After working out a few codes, I get the following string called ipString. I would like to display the string in a textview.
Here is what I have for now.
What should I add to make it work?
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.d("Rami","Rami");
DefaultHttpClient httpclient = new DefaultHttpClient(new BasicHttpParams());
HttpPost httppost = new HttpPost("http://jsonip.com");
// Depends on your web service
httppost.setHeader("Content-type", "application/json");
InputStream inputStream = null;
String result = null;
try {
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
inputStream = entity.getContent();
// json is UTF-8 by default
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
result = sb.toString();
JSONObject jObject = new JSONObject(result);
String ipString = jObject.getString("ip");
Log.d("ip", ipString);
} catch (Exception e) {
// Oops
}
finally {
try{if(inputStream != null)inputStream.close();}catch(Exception squish){}
}
TextView myTextView = (TextView) findViewById(R.id.textview1);
Use setText() this way:
TextView myTextView = (TextView) findViewById(R.id.textview1);
myTextView.setText(ipString);
Anyway you should put those two lines inside your try, that way it would only print the String if the HTTP Request was successful.
try {
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
inputStream = entity.getContent();
// json is UTF-8 by default
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
result = sb.toString();
JSONObject jObject = new JSONObject(result);
String ipString = jObject.getString("ip");
Log.d("ip", ipString);
TextView myTextView = (TextView) findViewById(R.id.textview1);
myTextView.setText(ipString);
} catch (Exception e) {
// Oops
}
finally {
try{if(inputStream != null)inputStream.close();}catch(Exception squish){}
}
BTW you should really read (and try to understand) the documentation and learn how to use your IDE.
Use setText() it will display your response text.
TextView myTextView = (TextView) findViewById(R.id.textview1);
myTextView.setText(ipString);
use setText() method like this :
String yourstringvalue;
TextView text = (TextView) findViewById(R.id.textviewID);
text.setText(yourstringvalue);
