您无法使用滑行为relativelayout图像中的已销毁活动启动加载

Question

我使用relativelayout设置图像.为什么我没有使用imageview手段,在relativelayout图像内,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:

TabMorePagesDetailActivity.java:

RelativeLayout rlPageCoverImg;

rlPageCoverImg = (RelativeLayout)findViewById(R.id.rl_club_cover_img);

@Override
        protected void onPostExecute(String response) {
            super.onPostExecute(response);

            dialog.dismiss();
        ............

    String coverIMGurl = cover_avatar_obj.getString("url");

    Log.e("ImgURL", coverIMGurl);

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

    @Override
    public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
    Drawable drawable = new BitmapDrawable(getResources(), resource);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                                            rlPageCoverImg.setBackground(drawable);
    }
    }
    });

    }else {

    rlPageCoverImg.setBackgroundResource(R.drawable.bg_golive);

    }



    @Override
 protected void onDestroy()
 {
    super.onDestroy();
    Glide.clear(rlPageCoverImg);

 }

layout.xml:

 <RelativeLayout
            android:id="@+id/rl_club_cover_img"
            android:layout_width="match_parent"
            android:layout_height="200dp"
            android:background="@drawable/cancel_image" >

  // Inside this relativelayout image, I'm using buttons and icons


 </RelativeLayout>

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

灵感来自 GitHub线程，我在加载任何图像之前使用它

final Context  context = getApplication().getApplicationContext();

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;
}

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

Glide.with(getApplicationContext())除非您真的需要，否则请不要使用，原因在这里讨论： Glide image loading with application context

此处概述了正确答案：https : //github.com/bumptech/glide/issues/1484#issuecomment-365625087

在 Kotlin 中，这可以写成一个扩展函数：

fun Context.isValidGlideContext() = this !is Activity || (!this.isDestroyed && !this.isFinishing)
