使用glide在recyclerView中加载图像时出错

Question

我有一个名为“ RecyclerTab1”的片段，其中保存着recyclerview布局。“ HomeManager”是recyclerview适配器。在那个recyclerview适配器中，我使用了Glide从可绘制文件夹中加载图像。我尝试运行该程序时遇到错误java.lang.IllegalArgumentException:我还包括RecyclerTab1类和用于recyclerview的HomeManager适配器

RecyclerTab1：

package com.example.root5solutions.mirrealtors.hometabfragments;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.example.root5solutions.mirrealtors.HomeRecyclerDetailActivity;

import com.example.root5solutions.mirrealtors.projectdatabase.HomeData;
import com.example.root5solutions.mirrealtors.projectdatabase.RecyclerClickListener;
import com.kogitune.activity_transition.ActivityTransitionLauncher;

public class RecyclerTab1 extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.home_tab1_recycler, container, false);
        RecyclerView rv = (RecyclerView) v.findViewById(R.id.home_recyclerview);
        LinearLayoutManager llm = new LinearLayoutManager(getContext());
        rv.setLayoutManager(llm);
        rv.smoothScrollToPosition(View.SCROLLBAR_POSITION_DEFAULT);
        rv.setHasFixedSize(true); // to improve performance
        rv.setAdapter(new HomeManager(getContext())); // the projectdatabase manager is assigner to the RV

        rv.addOnItemTouchListener( // and the click is handled
                new RecyclerClickListener(getContext(), new RecyclerClickListener.OnItemClickListener() {
                    @Override
                    public void onItemClick(View view, int position) {
                        Intent intent = new Intent(getActivity(), HomeRecyclerDetailActivity.class);
                        intent.putExtra(HomeRecyclerDetailActivity.ID, HomeData.PROJECTS[position].getId());
                        ActivityTransitionLauncher.with(getActivity()).from(view).launch(intent);
                    }
                }));
        return v;
    }
}

Answer 1

你得到这样的错误：

IllegalArgumentException: Unknown type class [Ljava.lang.String;

它可能为Glide.load（）提供了String []。

请在这里检查：

Glide.with(context)
            .load(Gallery_Constants.IMAGES)
            .diskCacheStrategy(DiskCacheStrategy.SOURCE)
            .into(viewHolder.mImage);

确保Gallery_Constants.IMAGES的类型正确。

Answer 2

Glide提供了许多.with（）方法是有原因的：它遵循生命周期。

想象一个动态添加到活动的片段。 在其onCreateView方法中，它将启动3MB图像的Glide加载。 现在，如果用户按下“后退”按钮并且“片段”被删除或整个活动被关闭，该怎么办？

1. 如果使用with（getActivity（）。getApplicationContext（））不会发生任何事情，那么将下载所有3MB的数据，然后对其进行解码，缓存，甚至可能设置为ImageView，然后再对其进行垃圾回收，因为对其的唯一引用来自滑动内部。

2. 如果与with（（Fragment）this）一起使用，则Glide订阅Fragment的生命周期事件，并且一旦Fragment停止，任何未完成的请求都应暂停； 销毁后，所有待处理的请求都会被清除。 这意味着映像下载将中途停止，并且该死片段将不再使用任何资源。

3. 如果与with（getActivity（））一起使用，则Glide订阅了Activity的生命周期事件，并且与上述情况相同，但仅当Activity停止或销毁时才发生。 因此，最佳实践是使用最接近的上下文/片段，以避免未完成的请求完成。

希望这对您有帮助。
