H5调用原生照片上传功能实现

原生调用相册和照相

    /**
     * 拍照
     */
    public void takePhotos(Activity activity, Uri contentUri, int callBackType) {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);// 启动系统相机
        takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, contentUri);// 更改系统默认存储路径
        activity.startActivityForResult(takePictureIntent, callBackType);
    }

    /**
     * 从相册获取
     */
    public void photoAlbum(Activity activity, Uri contentUri, int callBackType) {
        Intent chooseIntent = new Intent(Intent.ACTION_GET_CONTENT);
        chooseIntent.addCategory(Intent.CATEGORY_OPENABLE);
        chooseIntent.setType("image/*");
        chooseIntent.putExtra(MediaStore.EXTRA_OUTPUT, contentUri);
        activity.startActivityForResult(chooseIntent, callBackType);
    }

    public void chooseImageDialog(Activity activity, Uri contentUri, int callBackType) {
        //获取拍照
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);// 启动系统相机
        takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, contentUri);// 更改系统默认存储路径
        //获取照片资源
        Intent contentSelectionIntent = new Intent(Intent.ACTION_GET_CONTENT);
        contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE);
        contentSelectionIntent.setType("*/*");
        Intent[] intentArray;
        if (takePictureIntent != null) {
            intentArray = new Intent[]{takePictureIntent};
        } else {
            intentArray = new Intent[0];
        }
        Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);
        chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent);
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);
        activity.startActivityForResult(chooserIntent, callBackType);
    }

1. H5提供的资源访问接口
2. Android原生的权限申请
3. Android资源URI的定义
4. Android拍照或者访问相册数据返回处理适配不同的Android系统手机
