windowmanager = getwindowmanager();

 display display = windowmanager getdefaultdisplay();

 int w = display getwidth();

 int h = display getheight();

bitmap bmp = bitmap createbitmap( w, h, config argb_8888 );

 //2 获取屏幕

 view decorview = this getwindow() getdecorview();decorview setdrawingcacheenabled(true);bmp = decorview getdrawingcache(); string savepath = getsdcardpath()+"/andydemo/screenimage"; //3 保存bitmaptry {file path = new file(savepath);//文件string filepath = savepath + "/screen_1 png";file file = new file(filepath);if(!path exists()){path mkdirs();}if (!file exists()) {file createnewfile();}fileoutputstream fos = null;fos = new fileoutputstream(file);if (null != fos) {bmp compress(bitmap compressformat png, 90,
