3) 图片选择

int mode = selectMode.getCheckedRadioButtonId() == R.id.mode_multiple ? ImagePickActivity.MODE_MULTIPLE : ImagePickActivity.MODE_SINGLE;boolean isShow = showCamera.getCheckedRadioButtonId() == R.id.camera_yes ? true : false;boolean isPreview = enablePreview.getCheckedRadioButtonId() == R.id.preview_enable ? true : false;boolean isCrop = enableCrop.getCheckedRadioButtonId() == R.id.crop_enable ? true : false;ImagePickActivity.start(ImageActivity.this, maxSelectNum, mode, isShow, isPreview, isCrop, ImagePickActivity.REQUEST_IMAGE);

same this

    /**     * 启动图片选择页面     *     * @param activity     * @param maxSelectNum  最大选择图片数量     * @param mode          单选or多选     * @param isShow        是否展示照相机     * @param enablePreview 是否允许预览     * @param enableCrop    是否允许裁剪     * @param requestCode   请求码     */    public static void start(Activity activity, int maxSelectNum, int mode, boolean isShow,                             boolean enablePreview, boolean enableCrop, int requestCode) {        Intent intent = new Intent(activity, ImagePickActivity.class);        intent.putExtra(EXTRA_MAX_SELECT_NUM, maxSelectNum);        intent.putExtra(EXTRA_SELECT_MODE, mode);        intent.putExtra(EXTRA_SHOW_CAMERA, isShow);        intent.putExtra(EXTRA_ENABLE_PREVIEW, enablePreview);        intent.putExtra(EXTRA_ENABLE_CROP, enableCrop);        activity.startActivityForResult(intent, requestCode);    }

Receive result in your onActivityResult Method

    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        if (resultCode == RESULT_OK && requestCode == ImagePickActivity.REQUEST_IMAGE) {            ArrayList<ImageFile> images = data.getParcelableArrayListExtra(Constant.RESULT_PICK_IMAGE);            // do something ...        }    }

4) 视频选择

boolean isShow = showCamera.getCheckedRadioButtonId() == R.id.camera_yes ? true : false;VideoPickActivity.start(VideoActivity.this, maxSelectNum, isShow,VideoPickActivity.REQUEST_VIDEO);

       /**      * 启动视频选择      *      * @param activity      * @param maxSelectNum 最大选择数量      * @param isShow       是否展示摄像头      * @param requestCode   请求码      */     public static void start(Activity activity, int maxSelectNum, boolean isShow, int requestCode) {         Intent intent = new Intent(activity, VideoPickActivity.class);         intent.putExtra(EXTRA_MAX_SELECT_NUM, maxSelectNum);         intent.putExtra(EXTRA_SHOW_CAMERA, isShow);         activity.startActivityForResult(intent, requestCode);     }

Receive result in your onActivityResult Method

    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        if (resultCode == RESULT_OK && requestCode == VideoPickActivity.REQUEST_VIDEO) {            ArrayList<VideoFile> videoFiles = data.getParcelableArrayListExtra(Constant.RESULT_PICK_VIDEO);            // do something...        }    }

5) 文件选择

String[] mSuffix = {"txt"};NormalFilePickActivity.start(FileActivity.this, maxSelectNum, mSuffix, NormalFilePickActivity.REQUEST_FILE);
