Question

是一个问答游戏，答案可以是文字或图像，我正在使用Gilde图像来加载它，但对于某些用户来说，即使互联网状况良好且图像质量较差，也无法加载图像。

我将复制所有代码，因为我不知道Gilde是否有问题。

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>

使用滑行的最好方法我在这里解释。

//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 （将其放入res-＆gt; 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" />

最后调用此方法

来自您的活动的

。

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

或

来自您的片段的

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

我已经关注了一切。

已添加.dontAnimate 添加了所有必要的权限，Internet，Access_Network_State

但没有任何作用。

最后我找到了图片无法加载的原因，我的图片网址没有http或https。我已将http://添加到我的图片网址前面并且加载完美。

Answer 3

在我的Glide 4.8.0中，将以下内容添加到Glide加载到的ImageView小部件中可以达到目的，但这很奏效。...

android:background="?attr/selectableItemBackgroundBorderless"

或者也是

android:background="@drawable/R.drawable.yourResourceFile

或者也是

android:background="@android:color/transparent"
