java - 在 Glide 中加载更多图像时出现内存不足错误

Question

已编辑:

• 在我的应用程序中，我在主页中加载了 300 多张图片。我使用 glide 加载图像。我收到 内存不足错误。

我在 ma​​nifest 中使用了 large heap true :

android:largeHeap="true"

滑行版本:

compile 'com.github.bumptech.glide:glide:3.7.0'

设备/安卓版本:

Nexus 设备 6.0 版本

Every images I'm getting from Json would be 800kb to 1mb.

activity_layout:

<RelativeLayout
    android:id="@+id/home_layout_bottom"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/home_layout_top_recycler"
    android:layout_margin="5dp">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv_list_tab_home_recycler"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clipToPadding="false"
        android:scrollbars="vertical"
        android:visibility="visible" />

    <TextView
        android:id="@+id/no_user_posts_item_tv_recycler"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/rv_list_tab_home_recycler"
        android:layout_marginTop="80dp"
        android:layout_centerHorizontal="true"
        android:text="@string/txt_no_posts_available"
        android:textColor="@color/txt_common_black"
        android:textSize="@dimen/txt_size" />
</RelativeLayout>

适配器代码:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder = null;

    final HomePostItems rowItem = getItem(position);

    LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    if (convertView == null) {

        convertView = mInflater.inflate(R.layout.lv_adapter_post_items_layout, null);

      holder = new ViewHolder();

      holder.ivPostedImage = (ImageView) convertView.findViewById(R.id.iv_posted_img);


        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

      ..................

          Glide.with(context).load(rowItem.getPosteduserpostimage())
                        .placeholder(R.drawable.golive_load_image).error(R.drawable.golive_cancel_image)
                        .override(600, 200)
                        .into(holder.ivPostedImage);

adapter_layout.xml:

<RelativeLayout
    android:id="@+id/rl_lv_user_post_adapter_img_holder_home"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:layout_marginLeft="1dp"
    android:layout_marginRight="1dp"
    android:layout_below="@+id/tv_user_posted_msg_post_items_home" >

    <ImageView
        android:id="@+id/iv_posted_img_home"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true"
        android:scaleType="fitXY"
        android:background="#ffffff"
        android:contentDescription="@string/cont_desc"/>
</RelativeLayout>

我不知道如何解决这个 OOM 问题。如果您已经熟悉这个问题，请分享您的建议。

Answer 1

• 我通过移除嵌套的 ScrollView 解决了这个问题回收站 View 。为什么发生 OutOfMemory 错误意味着，加载更多时主页中有超过 200 张图片，它正在加载所有 200 张图片，因为使用recyclerview 上方的嵌套 ScrollView 。

• 所以我无法在logcat image view width and height中一一检查适配器。

• 移除嵌套 ScrollView 后修复了内存不足错误。因为它回家时只会加载设备中显示的 3 张图像 Activity 。

• 同时检查 this ，如何使用滚动而不是嵌套 ScrollView 。
