    <p>I have a long text and fixed size textView. How can show the text page by page? Users will interactive with the program in this way: He swipe left or right to turn to next or previous page.</p> <p>Currently, I create a PageManager to do this job. But it's very limited. The core code to process the text is:</p> <pre><code>while (true) { newLineIndex = TextUtils.indexOf(content, '\n', processIndex); if (newLineIndex == -1) {// till the end of content charCount = paint.breakText(content, processIndex, content.length(), false, leftLines * lineWidth, width); } else { charCount = paint.breakText(content, processIndex, ++newLineIndex, false, leftLines * lineWidth, width); } leftLines = (int) ((leftLines * lineWidth - width[0]) / lineWidth); processIndex += charCount; if (leftLines &lt; 1 || processIndex &gt;= content.length()) { page = new Page(); page.endIndex = processIndex; page.startIndex = pageBaseLine; page.content = content.subSequence(page.startIndex, page.endIndex); result.add(page); pageBaseLine = processIndex; leftLines = lineNumber; } if (processIndex &gt;= content.length()) { break; } } </code></pre> <p>The limitation is the page may truncate the text like </p> <pre><code>|A lon| |g wor| |d man| </code></pre> <p>// a long word man</p> <p>or incorrec lines due to word wrapping:</p> <p>//Page Manager calculates this(2 lines):</p> <pre><code>|a sentence with loooooooo| |ooong word abcdefghijklmn| </code></pre> <p>//But actually in text view(3 lines):</p> <pre><code>|a sentence with | |looooooooooong word | |abcdefghijklmn | </code></pre> <p>So the final line count is more than calculation. So my page manager is stupid. Would any one help me? thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
