android - How to capture invisible content of Tab and Recyclerview in Adroid? -


i have layout contain tablayout , viewpager, have 3 tab.layout code 

<android.support.v4.widget.nestedscrollview     android:id="@+id/nest_scrollview"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:cliptopadding="false"     app:layout_behavior="@string/appbar_scrolling_view_behavior">      <linearlayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="vertical">          <android.support.design.widget.tablayout             android:id="@+id/tabs"             android:layout_width="match_parent"             android:layout_height="?attr/actionbarsize"             android:layout_gravity="bottom"             android:background="@color/tab_background"             app:tabindicatorcolor="@color/colorprimary" />          <android.support.v4.view.viewpager             android:id="@+id/pager"             android:layout_width="match_parent"             android:layout_height="match_parent"             app:layout_behavior="@string/appbar_scrolling_view_behavior" />     </linearlayout>  </android.support.v4.widget.nestedscrollview>

now take screen shot, should take tab , it's contain.

i used below code take screen shot, it's take visible part on screen.

public bitmap takescreenshot() {         view rootview = findviewbyid(android.r.id.content).getrootview();         rootview.setdrawingcacheenabled(true);         return rootview.getdrawingcache();     }      public void savebitmap(bitmap bitmap) {         imagepath = new file(environment.getexternalstoragedirectory() + "/screenshot.png");         fileoutputstream fos;         try {             fos = new fileoutputstream(imagepath);             bitmap.compress(bitmap.compressformat.jpeg, 100, fos);             fos.flush();             fos.close();         } catch (filenotfoundexception e) {             log.e("grec", e.getmessage(), e);         } catch (ioexception e) {             log.e("grec", e.getmessage(), e);         }     }

you can capture entire recyclerview using below code.

public class utils {     public utils() {     }      public bitmap getscreenshotfromrecyclerview(recyclerview view) {         bitmap bigbitmap = null;          recyclerview.adapter adapter = view.getadapter();          if (adapter != null) {             int size = adapter.getitemcount();             int height = 0;             paint paint = new paint();             int iheight = 0;             final int maxmemory = (int) (runtime.getruntime().maxmemory() / 1024);              // use 1/8th of available memory memory cache.             final int cachesize = maxmemory / 8;             lrucache<string, bitmap> bitmacache = new lrucache<>(cachesize);             (int = 0; < size; i++) {                 recyclerview.viewholder holder = adapter.createviewholder(view, adapter.getitemviewtype(i));                 adapter.onbindviewholder(holder, i);                 holder.itemview.measure(view.measurespec.makemeasurespec(view.getwidth(), view.measurespec.exactly),                         view.measurespec.makemeasurespec(0, view.measurespec.unspecified));                 holder.itemview.layout(0, 0, holder.itemview.getmeasuredwidth(), holder.itemview.getmeasuredheight());                 holder.itemview.setdrawingcacheenabled(true);                 holder.itemview.builddrawingcache();                 bitmap drawingcache = holder.itemview.getdrawingcache();                 if (drawingcache != null) {                     bitmacache.put(string.valueof(i), drawingcache);                 } //                holder.itemview.setdrawingcacheenabled(false); //                holder.itemview.destroydrawingcache();                 height += holder.itemview.getmeasuredheight();             }              bigbitmap = bitmap.createbitmap(view.getmeasuredwidth(), height, bitmap.config.argb_8888);             canvas bigcanvas = new canvas(bigbitmap);             bigcanvas.drawcolor(color.white);              (int = 0; < size; i++) {                 bitmap bitmap = bitmacache.get(string.valueof(i));                 bigcanvas.drawbitmap(bitmap, 0f, iheight, paint);                 iheight += bitmap.getheight();                 bitmap.recycle();             }         }         storeimage(bigbitmap, "myrecipetest.jpg");         return bigbitmap;     }      /**      * convert bitmap image , save sdcard.      *      * @param imagedata -bitmap image.      * @param filename  -name of image.      * @return      */     public boolean storeimage(bitmap imagedata, string filename) {         // path external storage (sd card)         file sdiconstoragedir = new file(environment.getexternalstoragedirectory()                 .getabsolutepath() + "/myappdir/");         // create storage directories, if don't exist         sdiconstoragedir.mkdirs();         try {             string filepath = sdiconstoragedir.tostring() + file.separator + filename;             fileoutputstream fileoutputstream = new fileoutputstream(filepath);             bufferedoutputstream bos = new bufferedoutputstream(fileoutputstream);             log.e("<== share ==>", "storeimage: image saved at----" + filepath);             // choose format if png doesn't suit             imagedata.compress(bitmap.compressformat.png, 100, bos);             bos.flush();             bos.close();         } catch (filenotfoundexception e) {             log.w("tag", "error saving image file: " + e.getmessage());             return false;         } catch (ioexception e) {             log.w("tag", "error saving image file: " + e.getmessage());             return false;         }         return true;     } }
