如何选择多张图片从画廊？ [英] How to select multiple images from gallery?

问题描述

我想从文件的位置选择多张图像。到目前为止，我已经成功地选择一个图像，但我怎么能选择两个图像组合在一起。

 意向意图=新的意图（Intent.ACTION_PICK）;
                intent.setType（图像/ *）;
                startActivityForResult（意向，STEP_4_REQUEST）;
 

然后在 onActivityResult（INT申请code，INT结果code，意图数据）方法如下：

 案例STEP_4_REQUEST：
            如果（结果code == RESULT_OK）{
                乌里selectedImage = data.getData（）;
                的String [] filePathColumn = {MediaStore.Images.Media.DATA};

                光标光标= getContentResolver（）查询（selectedImage，
                        filePathColumn，NULL，NULL，NULL）;
                cursor.moveToFirst（）;

                INT参数：columnIndex = cursor.getColumnIndex（filePathColumn [0]）;
                字符串文件路径= cursor.getString（参数：columnIndex）;
                cursor.close（）;

                位图yourSelectedImage = BitmapFactory.de codeFILE（文件路径）;
            }

I am trying to select multiple images from a file location. So far I have managed to select one image but how can I select two images together.

Intent intent =new Intent(Intent.ACTION_PICK);
                intent.setType("image/*");
                startActivityForResult(intent, STEP_4_REQUEST);

Then in the onActivityResult(int requestCode, int resultCode, Intent data) method the following:

case STEP_4_REQUEST:
            if (resultCode == RESULT_OK) {
                Uri selectedImage = data.getData();
                String[] filePathColumn = { MediaStore.Images.Media.DATA };

                Cursor cursor = getContentResolver().query(selectedImage,
                        filePathColumn, null, null, null);
                cursor.moveToFirst();

                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                String filePath = cursor.getString(columnIndex);
                cursor.close();

                Bitmap yourSelectedImage = BitmapFactory.decodeFile(filePath);
            }
