    text
    copied!<p>I am in the process of developing an e-book reader application for android 3.0 tablets. To begin with I have a large chunk of String data. I want to split/break that String into pages based on the screen size of the device [I am planning to use text switcher or view flipper]. Though I tried using getWindowManager() method I could not get the preferred results. </p> <p>In the following thread it is mentioned that Text Switcher automatically breaks the text according to the screen size. But I do not think so. <a href="https://stackoverflow.com/questions/6406882/managing-text-in-android-applicaiton-like-in-a-ebook">Managing text in android applicaiton like in a eBook</a></p> <p>This is the logic I used :</p> <pre><code> // retreiving the flipper flipper = (ViewFlipper) findViewById(R.id.new_view_flipper); // obtaining screen dimensions Display display = getWindowManager().getDefaultDisplay(); int screenWidth = display.getWidth(); int screenHeight = display.getHeight(); // contentString is the whole string of the book while (contentString != null &amp;&amp; contentString.length() != 0) { totalPages ++; // creating new textviews for every page TextView contentTextView = new TextView(this); contentTextView.setWidth(ViewGroup.LayoutParams.FILL_PARENT); contentTextView.setHeight(ViewGroup.LayoutParams.FILL_PARENT); contentTextView.setMaxHeight(screenHeight); contentTextView.setMaxWidth(screenWidth); float textSize = contentTextView.getTextSize(); Paint paint = new Paint(); paint.setTextSize(textSize); int numChars = 0; int lineCount = 0; int maxLineCount = screenHeight/contentTextView.getLineHeight(); contentTextView.setLines(maxLineCount); while ((lineCount &lt; maxLineCount) &amp;&amp; (numChars &lt; contentString.length())) { numChars = numChars + paint.breakText(contentString.substring(numChars), true, screenWidth, null); lineCount ++; } // retrieve the String to be displayed in the current textbox String toBeDisplayed = contentString.substring(0, numChars); contentString = contentString.substring(numChars); contentTextView.setText(toBeDisplayed); flipper.addView(contentTextView); numChars = 0; lineCount = 0; } </code></pre>

An individual column

Larger individual text columns get their own page to allow for proper reading.
