关于android截图的一些方法

这里只记录一些链接，对于我的需求，只需要，

public static String createScreenShot(View v)     {        //测试截屏功能    SimpleDateFormat sdf = new SimpleDateFormat( "yyyy-MM-dd_HH-mm-ss",Locale.US);    String dirPath=Mapplication.SDPATH+Constants.QZ_PATH;    File dirFile=new File(dirPath);    if(!dirFile.exists())    {     dirFile.mkdir();    }     String  fname = Mapplication.SDPATH+Constants.QZ_PATH+sdf.format(new Date())+ ".png";          v.setDrawingCacheEnabled(true);     v.buildDrawingCache();      Bitmap bitmap = v.getDrawingCache();      if(bitmap  != null)    {          Bitmap bmpall=Bitmap.createBitmap(Mapplication.screen[0],CommonFun.dip2px(Mapplication.getContext(), 250),Config.ARGB_8888);                 Canvas canvas=new Canvas(bmpall);       Bitmap bmp1 = BitmapFactory.decodeResource(Mapplication.getContext().getResources(),R.drawable.pb_score_bg);       canvas.drawBitmap(bmp1,0,0,null);

      canvas.drawBitmap(bitmap,0,0,null);

            System.out.println("bitmap got!");             try{               FileOutputStream  out = new FileOutputStream(fname);               bmpall.compress(Bitmap.CompressFormat.PNG,100, out);               System.out.println("file" + fname + "output done.");               return fname;             }catch(Exception e) {               e.printStackTrace();               return "";             }           }else{             System.out.println("bitmap s NULL!");             return "";           }       }

用view getdrawingcache来截图(需求是只需要截特定的一部分)，但是这样的图是没有背景的，所以 Canvas canvas=new Canvas(bmpall);       Bitmap bmp1 = BitmapFactory.decodeResource(Mapplication.getContext().getResources(),R.drawable.pb_score_bg);       canvas.drawBitmap(bmp1,0,0,null);

      canvas.drawBitmap(bitmap,0,0,null); 是用canvas来绘制背景和图，，测试Ok
