使用静态方法来startActivity

使用PhotoView来显示一个图片

PhotoActivity.java

    private static final String IMAGE_PATH = "image_path";    private static final String IMAGE_URI = "image_uri";    public static void startPhotoActivity(Context context, String path) {        Intent intent = new Intent(context, PhotoActivity.class);        intent.putExtra(IMAGE_PATH, path);        context.startActivity(intent);    }    public static void startPhotoActivity(Context context, Uri imageUri) {        Intent intent = new Intent(context, PhotoActivity.class);        intent.putExtra(IMAGE_URI, imageUri);        context.startActivity(intent);    }

调用方式：

传递String值，即图片文件路径，可在调用照相机后将保存到指定文件中：

private static final String TAKE_PHOTO_FILE_PATH =            Environment.getExternalStorageDirectory().getAbsolutePath()                    + "/" + "test_take_picture.jpg";PhotoActivity.startPhotoActivity(this, TAKE_PHOTO_FILE_PATH);

传递Uri值，即图片的Uri，在调用图片选择器返回时得到Uri使用：

PhotoActivity.startPhotoActivity(this, mPickPictureImageUri);
