路径无效时如何使毕加索显示默认图像 [英] how to make picasso display default image when there is an invalid path

问题描述

我在这里显示一个默认图像名称R.drawable.avatar_placeholder时遇到问题.如果来自Web服务的链接非空，但错误404.表示该链接路径上没有任何图像.如果我在下面运行此功能，则会显示字符串"path not empty"，但无法显示图像.任何建议都欢迎.谢谢.

I am having one issue on display a default image name here R.drawable.avatar_placeholder. When the link from webservice is non empty, but error 404. means there isn't any image on that link path. Which if i run this function below, the string "path not empty" is shown, but it failed to display the image. Any suggestion is welcomed. Thanks.

private void loadProfileDetails() {
        Logger.d(UI_LoginFragmentWithPin.class, "loadProfileDetails profile image: " + PrefUtils.readString(Constant.PREF_PROFILE_IMAGE));
        if (!TextUtils.isEmpty(PrefUtils.readString(Constant.PREF_PROFILE_IMAGE))){
            Utils.println("path not empty");
            LPicasso.getInstance(getActivity())
                    .load(PrefUtils.readString(Constant.PREF_PROFILE_IMAGE))
                    .config(Bitmap.Config.RGB_565)
                    .resize(200, 200)
                    .centerCrop()
                    .into(imgProfile);
        }else {
            Utils.println("path empty");
            LPicasso.getInstance(getActivity())
                    .load(R.drawable.avatar_placeholder)
                    .config(Bitmap.Config.RGB_565)
                    .resize(200, 200)
                    .centerCrop()
                    .into(imgProfile);

        }
        tvEmail.setText(PrefUtils.readString(Constant.PREF_EMAIL));
        tvName.setText(PrefUtils.readString(Constant.PREF_USER_NAME) + " " + PrefUtils.readString(Constant.PREF_USER_SURNAME));
    }

推荐答案

尝试一下，

将错误图像设置为占位符图像

Set error image as your place holder image

    if(!PrefUtils.readString(Constant.PREF_PROFILE_IMAGE).equals("")) 
    {
        Picasso.with(context).load(PrefUtils.readString(Constant.PREF_PROFILE_IMAGE)).resize(200,200).centerCrop().error(R.drawable.avatar_placeholder).into(imgProfile);
    }
    else
    {
        Picasso.with(context).load(R.drawable.avatar_placeholder).error(R.drawable.avatar_placeholder).resize(200,200).centerCrop().into(imgProfile);
    }

等级:

    compile 'com.squareup.picasso:picasso:2.5.2'
