I’m trying to read a text file line by line using InputStream from the assets directory in Android.
I want to convert the InputStream to a BufferedReader to be able to use the readLine().
I have the following code:
InputStream is; is = myContext.getAssets().open ("file.txt"); BufferedReader br = new BufferedReader (is);
The third line drops the following error:
Multiple markers at this line The constructor BufferedReader (InputStream) is undefinded.
What I’m trying to do in C++ would be something like:
StreamReader file; file = File.OpenText ("file.txt"); line = file.ReadLine(); line = file.ReadLine(); ...
What am I doing wrong or how should I do that? Thanks!
BufferedReader can’t wrap an
InputStream directly. It wraps another
Reader. In this case you’d want to do something like:
BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"));
A BufferedReader constructor takes a reader as argument, not an InputStream. You should first create a Reader from your stream, like so:
Reader reader = new InputStreamReader(is); BufferedReader br = new BufferedReader(reader);
Preferrably, you also provide a Charset or character encoding name to the StreamReader constructor. Since a stream just provides bytes, converting these to text means the encoding must be known. If you don’t specify it, the system default is assumed.
InputStream is; InputStreamReader r = new InputStreamReader(is); BufferedReader br = new BufferedReader(r);
