Android中截取当前屏幕图片

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();                                      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-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
