android截屏

private void printScreen(boolean save) {//截屏View view = this.getWindow().getDecorView();//this是当前的Activity// if (view.isDrawingCacheEnabled()) {view.setDrawingCacheEnabled(true);Calendar c = Calendar.getInstance();String date = c.get(Calendar.YEAR) + "-" + (c.get(Calendar.MONTH) + 1) + "-" + c.get(Calendar.DAY_OF_MONTH) + "  " + c.get(Calendar.HOUR_OF_DAY) + "-" + c.get(Calendar.MINUTE) + "-" + c.get(Calendar.SECOND);// }view.buildDrawingCache();Bitmap bmp = view.getDrawingCache();imagePath = ConstValue.MY_ALBUM_DIR + "/" + date + ".jpg";//路径writePhotoJpg(bmp, imagePath);// FileSaveAsync myAsync = new FileSaveAsync(bmp, imagePath, true);// myAsync.execute();}

保存到sd卡下的方法：（记得加上写入sd卡的权限）

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" ></uses-permission>

public void writePhotoJpg(Bitmap data, String pathName) {File file = new File(pathName);try {file.createNewFile();// BufferedOutputStream os = new BufferedOutputStream(// new FileOutputStream(file));FileOutputStream os = new FileOutputStream(file);data.compress(Bitmap.CompressFormat.JPEG, 100, os);os.flush();os.close();MyDebug.i("writePhotoJpg");} catch (Exception e) {e.printStackTrace();}}public void writePhotoPng(Bitmap data, String pathName) {File file = new File(pathName);try {file.createNewFile();FileOutputStream os = new FileOutputStream(file);// BufferedOutputStream os = new BufferedOutputStream(// new FileOutputStream(file));data.compress(Bitmap.CompressFormat.PNG, 100, os);os.flush();os.close();MyDebug.i("writePhotoPng");} catch (Exception e) {e.printStackTrace();}}

另外几种方法，没仔细测试过：仅供参考

 //抓屏的方式生成照片   public static Bitmap printScreen(Context context) {View view = ((Activity) context).getWindow().getDecorView();// if (view.isDrawingCacheEnabled()) {view.setDrawingCacheEnabled(true);//Calendar c = Calendar.getInstance();//String date = c.get(Calendar.YEAR) + "-" + (c.get(Calendar.MONTH) + 1) + "-" + c.get(Calendar.DAY_OF_MONTH) + "  " + c.get(Calendar.HOUR_OF_DAY) + "-" + c.get(Calendar.MINUTE) + "-" + c.get(Calendar.SECOND);// }view.buildDrawingCache();Bitmap bmp = view.getDrawingCache();return bmp;/*imagePath = ConstValue.MY_ALBUM_DIR + "/" + date + ".jpg";ImageFile.writePhotoJpg(bmp, imagePath);*/// FileSaveAsync myAsync = new FileSaveAsync(bmp, imagePath, true);// myAsync.execute();}         public static Bitmap catchScreen(View v1) {        v1.setDrawingCacheEnabled(true);        Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());        v1.setDrawingCacheEnabled(false);        return bitmap;          }
