Question

I have a text file added as a raw resource. The text file contains text like:

b) IF APPLICABLE LAW REQUIRES ANY WARRANTIES WITH RESPECT TO THE
SOFTWARE, ALL SUCH WARRANTIES ARE 
LIMITED IN DURATION TO NINETY (90)
DAYS FROM THE DATE OF  DELIVERY.

(c) NO ORAL OR WRITTEN INFORMATION OR
ADVICE GIVEN BY  VIRTUAL ORIENTEERING,
ITS DEALERS, DISTRIBUTORS, AGENTS OR
EMPLOYEES SHALL CREATE A WARRANTY OR
IN ANY WAY INCREASE THE SCOPE OF ANY
WARRANTY PROVIDED HEREIN. 

(d) (USA only) SOME STATES DO NOT
ALLOW THE EXCLUSION OF IMPLIED
WARRANTIES, SO THE ABOVE EXCLUSION MAY
NOT  APPLY TO YOU. THIS WARRANTY GIVES
YOU SPECIFIC LEGAL  RIGHTS AND YOU MAY
ALSO HAVE OTHER LEGAL RIGHTS THAT 
VARY FROM STATE TO STATE.

On my screen I have a layout like this:

<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"
                     android:layout_width="fill_parent" 
                     android:layout_height="wrap_content" 
                     android:gravity="center" 
                     android:layout_weight="1.0"
                     android:layout_below="@+id/logoLayout"
                     android:background="@drawable/list_background"> 
            
            <ScrollView android:layout_width="fill_parent"
                        android:layout_height="fill_parent">
                        
                    <TextView  android:id="@+id/txtRawResource" 
                               android:layout_width="fill_parent" 
                               android:layout_height="fill_parent"
                               android:padding="3dip"/>
            </ScrollView>  
   
    </LinearLayout>

The code to read the raw resource is:

TextView txtRawResource= (TextView)findViewById(R.id.txtRawResource);

txtDisclaimer.setText(Utils.readRawTextFile(ctx, R.raw.rawtextsample);

public static String readRawTextFile(Context ctx, int resId)
{
    InputStream inputStream = ctx.getResources().openRawResource(resId);

    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

    int i;
    try {
        i = inputStream.read();
        while (i != -1)
        {
            byteArrayOutputStream.write(i);
            i = inputStream.read();
        }
        inputStream.close();
    } catch (IOException e) {
        return null;
    }
    return byteArrayOutputStream.toString();
}

The text is shown but after each line I get the strange characters []. How can I remove the characters? I think it’s a newline.

Answer 1

What if you use a character-based BufferedReader instead of byte-based InputStream?

BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String line = reader.readLine();
while (line != null) { 
    ...
    line = reader.readLine();
}

Don’t forget that readLine() skips the new-lines!
