android-如何在RecyclerView的适配器中获取运行时权限？请查看详细信息

我正在开发一个需要以下运行时权限才能启动服务的应用程序：

@TargetApi(Build.VERSION_CODES.M)
    public void startFloatyForAboveAndroidL() {
        if (!Settings.canDrawOverlays(this)) {
            Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                    Uri.parse("package:" + getPackageName()));
            startActivityForResult(intent, PERMISSION_REQUEST_CODE);
        } else {
            floaty.startService();
        }
    }


    @TargetApi(Build.VERSION_CODES.M)
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == PERMISSION_REQUEST_CODE) {
            if (Settings.canDrawOverlays(this)) {
                floaty.startService();
            } else {
                Spanned message = Html.fromHtml("Please allow this permission, so <b>Floaties</b> could be drawn.");
                Toast.makeText(this, message, Toast.LENGTH_LONG).show();
            }
        }

但是,当我从适配器的bindView()启动服务时,我不知道在哪里编写此代码.我在这里使用FastAdapter.

这是HRequest.java文件的代码：

public class HRequest extends AbstractItem<HRequest, HRequest.ViewHolder> {

        public String imageURL;

        public HRequest() {

        }

        public HRequest(String imageURL) {
            this.imageURL = imageURL;
        }

        // Fast Adapter methods
        @Override
        public int getType() {
            return R.id.recycler_view;
        }
        @Override
        public int getLayoutRes() {
            return R.layout.h_request_list_row;
        }
        @Override
        public void bindView(ViewHolder holder) {
            super.bindView(holder);

            holder.imageURL.setText(imageURL);

        }
        // Manually create the ViewHolder class
        protected static class ViewHolder extends RecyclerView.ViewHolder {

            TextView imageURL;

            public ViewHolder(View itemView) {
                super(itemView);
                imageURL = (TextView)itemView.findViewById(R.id.imageURL);

if (!imageURL.getText().toString().isEmpty()) {

if (imageURL.getText().toString().startsWith("https://firebasestorage.googleapis.com/") || imageURL.getText().toString().startsWith("content://")) {
                    Picasso.with(itemView.getContext())
                            .load(imageURL.getText().toString())
                            .into(homelessImage);
                } else {
                    Toast.makeText(itemView.getContext(), "some problem", Toast.LENGTH_SHORT).show();
                }

            } else {
                Toast.makeText(itemView.getContext(), "no imageUID found", Toast.LENGTH_SHORT).show();
            }

            }
        }

    }

请让我知道如何以及如何编写此代码以寻求许可并防止该应用在Android M上崩溃.

解决方法:

I’m developing an app in which I need the following runtime permission to start a service

从技术上讲,这不是运行时权限,尽管您需要该代码或类似的代码.

I have no idea where to write this code

我会在填充RecyclerView之前这样做.例如,当用户启动活动时,如果您没有权限,则显示“设置”屏幕,只有获得权限后,才在RecyclerView上设置适配器.
