How can I read a text file in Android?
I want to read the text from a text file. In the code below, an exception occurs (that means it goes to the catch
block). I put the text file in the application folder. Where should I put this text file (mani.txt) in order to read it correctly?
try
{
InputStream instream = openFileInput("E:\\test\\src\\com\\test\\mani.txt");
if (instream != null)
{
InputStreamReader inputreader = new InputStreamReader(instream);
BufferedReader buffreader = new BufferedReader(inputreader);
String line,line1 = "";
try
{
while ((line = buffreader.readLine()) != null)
line1+=line;
}catch (Exception e)
{
e.printStackTrace();
}
}
}
catch (Exception e)
{
String error="";
error=e.getMessage();
}
Solution 1:
Try this :
I assume your text file is on sd card
//Find the directory for the SD Card using the API
//*Don't* hardcode "/sdcard"
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.toString());

If you want to read file from sd card. Then following code might be helpful for you.
StringBuilder text = new StringBuilder();
try {
File sdcard = Environment.getExternalStorageDirectory();
File file = new File(sdcard,"testFile.txt");
BufferedReader br = new BufferedReader(new FileReader(file));
String line;
while ((line = br.readLine()) != null) {
text.append(line);
Log.i("Test", "text : "+text+" : end");
text.append('\n');
} }
catch (IOException e) {
e.printStackTrace();
}
finally{
br.close();
}
TextView tv = (TextView)findViewById(R.id.amount);
tv.setText(text.toString()); ////Set the text to text view.
}
}
If you wan to read file from asset folder then
AssetManager am = context.getAssets();
InputStream is = am.open("test.txt");
Or If you wan to read this file from res/raw
foldery, where the file will be indexed and is accessible by an id in the R file:
InputStream is = getResources().openRawResource(R.raw.test);
Good example of reading text file from res/raw folder
