Question

我在显示自定义手机图库时遇到了麻烦。

首先，我需要在gridview中显示图像文件夹（例如电话库），并且在选择任何文件夹时，它必须显示其中的图片并且应该允许多个选择，以便我可以选择多张图片。

可以实现吗？

如果是，该怎么做？

Answer 1

要打开图库：

//open gallery to choose image

    private void captureImage() {

        // Create intent to Open Image applications like Gallery, Google Photos
        Intent galleryIntent = new Intent(Intent.ACTION_PICK,
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        // Start the Intent
        startActivityForResult(galleryIntent, RESULT_LOAD_IMG);

    }

从图库中选择图像时，会调用以下函数，实现它以保存所选图像。

// When Image is selected from Gallery
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        try {
            // When an Image is picked
            if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK
                    && null != data) {
                // Get the Image from data

                Uri selectedImage = data.getData();
                String[] filePathColumn = { MediaStore.Images.Media.DATA };

                // Get the cursor
                Cursor cursor = getContentResolver().query(selectedImage,
                        filePathColumn, null, null, null);
                // Move to first row
                cursor.moveToFirst();

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

                // Get the Image's file name
                String fileNameSegments[] = imgPath.split("/");
                fileName = fileNameSegments[fileNameSegments.length - 1];

                // successfully selected the image
                // launching upload activity

                tvCapturePicture.setText(fileName);

            } else {
                Toast.makeText(this, "You haven't picked any Image",
                        Toast.LENGTH_LONG).show();
            }
        } catch (Exception e) {
            Toast.makeText(this, "Something went wrong ,please try again , ",
                    Toast.LENGTH_LONG).show();
        }

    }
