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BitmapWindowManager 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(); Toast.makeText(mContext, "截屏文件已保存至SDCard/AndyDemo/ScreenImage/下", Toast.LENGTH_LONG).show(); } } 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。
