    <p>It might be too late for answer, but I'll post how I solved problem like this.</p> <p>I made similar project, but for android tablet. In my application, I have system bottom bar, my navigation bar and header. These parts of Activity don't take part in text preview, so I want to exclude them in calculations. For screen 750px these parts takes 24% of screen, it's about 180px. So I use the following algorithm to view text in text view:</p> <ol> <li>Calculate <em>actual height</em> to view text, it's height of my textview: ScreenHeight - ScreenHeight*0.24</li> <li>Set text size, for example 14.0</li> <li>Calculate number of lines in text file</li> <li>Calculate number of lines per page: Actual height/ text size</li> <li>Calculate number of pages and load them in HashMap</li> </ol> <hr> <pre><code>Display display = getWindowManager().getDefaultDisplay(); int width = display.getWidth(); int height = display.getHeight() — 0.24*display.getHeight(); mLinesInPage = (int) (Math.floor(height / mTextSize)); mPages = (int) (Math.ceil(mLinesInText / mLinesInPage)); </code></pre> <hr> <p>Formatting and other transformations executes "on the fly". Nothing difficult, but works for me. There are examples</p> <p><em>Before using algorithm:</em></p> <p><img src="https://i.stack.imgur.com/agOC1.png" alt="enter image description here"></p> <p><em>After using algorithm:</em></p> <p><img src="https://i.stack.imgur.com/tHd1R.png" alt="enter image description here"></p> <p><img src="https://i.stack.imgur.com/nd2Np.png" alt="enter image description here"></p>

    2. COI have same issue, but i cant understand how your code is solving a problem... Maybe its because i dont get how you calculate 'mLinesInText'. Can you explain a bit more please @Sigrlami

    3. CO@kort.es You can get *mLinesInText* by reading hole text and counting newline delimiter *"\n"*. Ofcourse, if you reformat text in some way, this parameter should be recalculated too.

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.
