我正在使用Android开发一个应用程序，其中必须拍摄我的一项活动的屏幕截图并将其作为附件邮寄.

I am making an application in Android in which I have to take screenshot of one of my activities and mail it as attachment.

我想获取当前页面的屏幕截图，然后通过电子邮件，蓝牙，Twitter或Facebook分享.

I want to take screenshot of the current page and then share it via email, Bluetooth, Twitter or Facebook.

我的代码如下:

@Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.menuselected1, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.ScreenShot: try { takeScreenShot(this); } catch (Exception e) { System.out.println(e); } return true; default: return super.onOptionsItemSelected(item); } } private static void savePic(Bitmap b, String strFileName) { FileOutputStream fos = null; try { fos = new FileOutputStream(strFileName); if (null != fos) { bpress(Bitmap.CompressFormat.PNG, 90, fos); System.out.println("b is:"+b); fos.flush(); fos.close(); } } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } public static void shoot(Activity a,String b) { //savePic(takeScreenShot(a), "sdcard/xx.png"); savePic(takeScreenShot(a), b); } private static Bitmap takeScreenShot(Activity activity) { View view = activity.getWindow().getDecorView(); view.setDrawingCacheEnabled(true); view.buildDrawingCache(); Bitmap b1 = view.getDrawingCache(); Rect frame = new Rect(); activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame); int statusBarHeight = frame.top; int width = activity.getWindowManager().getDefaultDisplay().getWidth(); int height = activity.getWindowManager().getDefaultDisplay() .getHeight(); // Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455); Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height - statusBarHeight); view.destroyDrawingCache(); return b; }

推荐答案
