        overridePendingTransition(R.anim.push_left_in, R.anim.hold);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.page);

        picturePath = getIntent().getStringExtra("selectedPhoto");

        Bitmap bitmap = BitmapFactory.decodeFile(picturePath);

                intent.setType("image/*");
                intent.putExtra(Intent.EXTRA_STREAM, Uri.parse(picturePath));
                startActivity(Intent.createChooser(intent, "Share"));

放入 onClickListener

                imageView.setDrawingCacheEnabled(true);
                Bitmap bitmap = imageView.getDrawingCache();
                File root = Environment.getExternalStorageDirectory();
                File cachePath = new File(root.getAbsolutePath() + "/DCIM/Camera/image.jpg");
                try {
                    cachePath.createNewFile();
                    FileOutputStream ostream = new FileOutputStream(cachePath);
                    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, ostream);
                    ostream.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }


                Intent share = new Intent(Intent.ACTION_SEND);
                share.setType("image/*");
                share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(cachePath));
                startActivity(Intent.createChooser(share,"Share via"));
