有时无法加载 Glide 图像 [英] Glide images sometimes are not loading

问题描述

是一个问答游戏，答案可以是文本或图像，我正在使用 Gilde 图像来加载它，但对于某些用户，图像无法加载，即使互联网良好且图像质量低.

Is a quiz game and the answer can be text or image, i'm using Gilde image to load it but for some users the images can't load, even if the internet is good and the images are in low quality.

我会复制所有代码，因为我不知道是不是 Gilde 问题.

I'll copy all the code because i have no idea if is Gilde problem or not.

if (AppConstant.arQuestionList.get(questionid).getArAnswer().get(i).getAtype()
                    .equalsIgnoreCase("image")) {
                txtOption = new ImageView(this);

                try {
                    Glide.with(QuestionActivity.this).load(AppConstant.arQuestionList.get(questionid)
                            .getArAnswer().get(i).getAnswer()).override(60, 60).into((ImageView)
                            txtOption);
                }catch (OutOfMemoryError e){
                    e.printStackTrace();
                }
                txtOption.setPadding(5, 5, 5, 5);

            } else {
                txtOption = new TextView(this);

                ((TextView) txtOption).setText(AppConstant.arQuestionList.get(questionid)
                        .getArAnswer().get
                                (i).getAnswer());
                ((TextView) txtOption).setTextColor(getResources().getColor(R.color.answer_color));
                ((TextView) txtOption).setTypeface(tf, Typeface.BOLD);
                ((TextView) txtOption).setGravity(Gravity.CENTER);
                txtOption.setPadding(10, 20, 10, 20);
            }

布局

    <LinearLayout
        android:id="@+id/answerwrap"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="@dimen/dp_30"
        android:layout_marginRight="@dimen/dp_30"
        android:layout_marginTop="@dimen/dp_30"
        android:orientation="vertical">

    </LinearLayout>

推荐答案

我在这里解释使用 glide 的最佳方式.

the best way to use glide I am explaining here.

//crete this method into your Utils class and call this method wherever you want to use.
//you can set these placeHolder() and error() image static as well. I made it as comment inside this method, then no need to use [placeHolderUrl and errorImageUrl] parameters. remove it from this method.
public static void loadImage(final Activity context, ImageView imageView, String url, int placeHolderUrl, int errorImageUrl) {
    if (context == null || context.isDestroyed()) return;

    //placeHolderUrl=R.drawable.ic_user;
    //errorImageUrl=R.drawable.ic_error;
        Glide.with(context) //passing context 
                .load(getFullUrl(url)) //passing your url to load image.
                .placeholder(placeHolderUrl) //this would be your default image (like default profile or logo etc). it would be loaded at initial time and it will replace with your loaded image once glide successfully load image using url.
                .error(errorImageUrl)//in case of any glide exception or not able to download then this image will be appear . if you won't mention this error() then nothing to worry placeHolder image would be remain as it is.
                .diskCacheStrategy(DiskCacheStrategy.ALL) //using to load into cache then second time it will load fast.
                .animate(R.anim.fade_in) // when image (url) will be loaded by glide then this face in animation help to replace url image in the place of placeHolder (default) image.
                .fitCenter()//this method help to fit image into center of your ImageView 
                .into(imageView); //pass imageView reference to appear the image.
}

fade_in.xml(放入res->anim)

fade_in.xml (put it into res->anim)

<set xmlns:android="http://schemas.android.com/apk/res/android">
<!--THIS ANIMATION IS USING FOR FADE IN -->

<alpha
    android:duration="800"
    android:fromAlpha="0.0"
    android:interpolator="@android:anim/decelerate_interpolator"
    android:toAlpha="1.0" />

最后调用这个方法

来自您的活动.

Utils.loadImage(YourClassName.this,mImageView,url,R.drawable.ic_user,R.drawable.ic_error);

或

来自你的片段

Utils.loadImage(getActivity,mImageView,url,R.drawable.ic_user,R.drawable.ic_error);
