该篇文章是说明在android手机或平板电脑中如何实现截取当前屏幕的功能，并把截取的屏幕保存到sdcard中的某个目录文件夹下面。
实现的代码如下：

/** * 获取和保存当前屏幕的截图 */private void getandsavecurrentimage() { //1.构建bitmap windowmanager 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bitmap try { 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, fos); fos.flush(); fos.close(); } } catch (exception e) { e.printstacktrace(); } } /** * 获取sdcard的目录路径功能 * @return */private string getsdcardpath(){ file sdcarddir = null; //判断sdcard是否存在 boolean sdcardexist = environment.getexternalstoragestate().equals(android.os.environment.media_mounted); if(sdcardexist){ sdcarddir = environment.getexternalstoragedirectory(); } return sdcarddir.tostring(); } |
由于要对sdcard进行操作，所以别忘记了在manifest.xml文件中赋以对sdcard的读写权限：

<uses-permission android:name="android.permission.write_external_storage"/> |
希望本文所述对大家学习android软件编程有所帮助。
