Question

我使用relativelayout来设置图像。为什么我没有使用imageview方法，在relativelayout图像中，我正在设置图标。

我不知道滑翔中究竟是什么问题。我已经发布了下面的堆栈跟踪和相关代码：

logcat的：

    @Override

 }

Answer 1

使用：

Glide.with(getApplicationContext()).load(...)

代替：

Glide.with(TabMorePagesDetailActivity.this).load(...)

希望它能解决你的问题〜

Answer 2

受GitHub thread的启发，我在加载任何图像之前都在使用它

final Context  context = getContext();
if (isValidContextForGlide(context) {
  // Load image via Glide lib using context
}

 public static boolean isValidContextForGlide(final Context context) {
    if (context == null) {
        return false;
    }
    if (context instanceof Activity) {
        final Activity activity = (Activity) context;
        if (activity.isDestroyed() || activity.isFinishing()) {
            return false;
        }
    }
    return true;
}

Answer 3

您可以简单地检查上下文是否被销毁;

if (context == null) {
    return
} else if (context !is Application) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        if (context is FragmentActivity) {
            if ((context as FragmentActivity).isDestroyed) {
                return
            }
        } else if (context is Activity) {
            if ((context as Activity).isDestroyed) {
                return
            }
        }
    }
}

这也可以表示为Kotlin扩展函数：

/**
 * Return true if this [Context] is available.
 * Availability is defined as the following:
 * + [Context] is not null
 * + [Context] is not destroyed (tested with [FragmentActivity.isDestroyed] or [Activity.isDestroyed])
 */
fun Context?.isAvailable(): Boolean {
    if (this == null) {
        return false
    } else if (this !is Application) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            if (this is FragmentActivity) {
                return !this.isDestroyed
            } else if (this is Activity) {
                return !this.isDestroyed
            }
        }
    }
    return true
}

Answer 4

我在几天之前遇到了同样的问题。我已经解决了这个问题，将Application上下文内存代表当前的Class上下文内存。

可能会对你有所帮助： -

使用此代码

 Glide.with(getApplicationContext())
           .load(coverIMGurl)
           .asBitmap()
           .signature(new StringSignature(String.valueOf(System.currentTimeMillis())))
                                    .into(new SimpleTarget<Bitmap>(500, 500) {....}

即使您遇到此问题，请仔细阅读本文“https://github.com/bumptech/glide/issues/1097”

此问题的概述：这是Glide库的问题。

Answer 5

使用具有正确生命周期的参数设置Glide。例如：在自定义视图中使用Glide.with(this)代替Glide.with(getContext())。

Answer 6

在活动中，我使用 Glide.with(getApplicatonContext()) ，在适配器中，我使用 Glide.with(myContext.getApplicatonContext())

//It works for me fine.

//for adapter

Context myContext;

//also initilize in `oncreateViewHolder`

@Override
    public MessagesHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.custom_messages_layout, parent, false);
        myContext = parent.getContext();
        return new MessagesHolder(view);
    }

Answer 7

这是一个 Kotlin 扩展，它汇集了上述几个答案 - this、this 和 this：

/**
 * Returns true when [Context] is unavailable or is about to become unavailable
 */
fun Context?.isDoomed(): Boolean = when (this) {
    null -> true
    is Application -> false
    is Activity -> (this.isDestroyed or this.isFinishing)
    else -> false
}

Answer 8

hi在frament的视图模型中即使按下返回按钮并退出程序，活动上下文也会保留。回到程序，您不需要重新评估上下文，因为上下文是静态的

@Override
    public void onBindViewHolder(@NonNull final viewholder viewholder, final int i) {
        final Model_Post model_post = list.get(i);
        Log.e(TAG, "onBindViewHolder: "+model_post.getImageurl());

        Glide.with(MainActivity.activity)
                .load(Uri.parse(model_post.getImageurl()))
                .diskCacheStrategy(DiskCacheStrategy.ALL)
                .into(viewholder.itemsPostBinding.imgvItempost);

    }

您必须在主要活动中执行此操作：

public static AppCompatActivity activity;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    activity = MainActivity.this;
}

Answer 9

请使用Glide.with（holder.itemView.getContext（））。load ...... 它已解决了我的问题ref https://github.com/bumptech/glide/issues/2690

Answer 10

您可以使用：Glide.with(getActivity()).load(....)

Answer 11

在使用Glide加载图像之前尝试此操作，在我的情况下，mirefer是StorageReference，miimagen是ImageView。我解决了这个问题。我希望它可以帮助你。

if (!this.isFinishing ()) {
                // Load the image using Glide
                Glide.with(YourActivity.this)
                        .using(new FirebaseImageLoader())
                        .load(mirefer)
                        .into(miimagen);
            }

您无法使用滑行为relativelayout图像中的已销毁活动启动加载
