Question

我正在开发一个项目，我必须从库中选择多张照片，并希望将它们保存在imageview数组中。我无法从imageview中选择任何图像。任何人都可以告诉我，我如何导入多个图像并将其保存在数组中？

     private void chooseimage() {
            final CharSequence[] items = {"Take Photo", "Choose from Library",
                    "Cancel"};

            android.app.AlertDialog.Builder builder = new android.app.AlertDialog.Builder(ActionStatusActivity.this);
            builder.setTitle("Add Photo!");
            builder.setItems(items, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int item) {
                    if (items[item].equals("Take Photo")) {
                        userChoosenTask = "Take Photo";
                        dialog.dismiss();
                        cameraIntent();
                    } else if (items[item].equals("Choose from Library")) {
                        userChoosenTask = "Choose from Library";
                        dialog.dismiss();
                      picimage();
                        //galleryIntent();

                    } else if (items[item].equals("Cancel")) {
                        dialog.dismiss();
                    }
                }
            });
            builder.show();
        }
          private void picimage() {

      }

                    && null != data) {

                if(data.getClipData() != null) {
                    int count = data.getClipData().getItemCount(); //evaluate the count before the for loop --- otherwise, the count is evaluated every loop.
                    for(int i = 0; i < count; i++)
                        imageUri = data.getClipData().getItemAt(i).getUri();

Intent intent = new Intent();
                intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
                if (Build.VERSION.SDK_INT < 19) {
                    intent.setAction(Intent.ACTION_GET_CONTENT);
                    intent = Intent.createChooser(intent, "Select file");
                } else {
                    intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
                    intent.addCategory(Intent.CATEGORY_OPENABLE);


//                    String[] mimetypes = { "*/*"};
                    String[] mimeTypes =
                            {"image/*"};

                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                        intent.setType(mimeTypes.length == 1 ? mimeTypes[0] : "*/*");
