    <p>Is there any way to get a <strong>high resolution</strong> screen shot of a certain view in an activity. </p> <p>I want to convert html content of my webview to PDF. For that I tried to take screen shot of the webview content and then converted it to PDF using itext. The resulted PDF is not in much more clarity. </p> <p>My code:</p> <pre><code> protected void takeimg() { Picture picture = mWebView.capturePicture(); Bitmap b = Bitmap.createBitmap(picture.getWidth(), picture.getHeight(), Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); picture.draw(c); // byte[] bt = b.getNinePatchChunk(); // Bitmap b; // View v1 = mWebView.getRootView(); // v1.setDrawingCacheEnabled(true); // b = Bitmap.createBitmap(v1.getDrawingCache()); // v1.setDrawingCacheEnabled(false); FileOutputStream fos = null; try { File root = new File(Environment.getExternalStorageDirectory(), "Sample"); if (!root.exists()) { root.mkdir(); } String sdcardhtmlpath = root.getPath().toString() + "/" + "temp_1.png"; fos = new FileOutputStream(sdcardhtmlpath); // fos = openFileOutput("samsp_1.jpg", MODE_WORLD_WRITEABLE); if (fos != null) { b.compress(Bitmap.CompressFormat.PNG, 100, fos); // fos.write(bt); fos.close(); } } catch (Exception e) { Log.e("takeimg", e.toString()); e.printStackTrace(); } } protected void pdfimg() { Document mydoc = new Document(PageSize.A3); try { File root = new File(Environment.getExternalStorageDirectory(), "Sample"); if (!root.exists()) { root.mkdir(); } String sdcardhtmlpath = root.getPath().toString() + "/"; mydoc.setMargins(0, 0, 0, 0); PdfWriter.getInstance(mydoc, new FileOutputStream(sdcardhtmlpath + PDFfilename)); mydoc.open(); Image image1 = Image.getInstance(sdcardhtmlpath + "temp_1.jpg"); image1.scalePercent(95f); mydoc.add(image1); // mydoc.newPage(); mydoc.close(); } catch (Exception e) { Log.e("pdi name", e.toString()); } } </code></pre>

    2. COWhy do you want to take a screenshot.. there are various libraries available which provides creation of PDF files on android. Just the get the content of your HTML page from the webview and use any lib to create a pdf. This screenshot technique will create more new problems then solving your original one.

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.
