我一直在使用回收站视图在片段上显示15张图像。图像位于可绘制文件夹中。我尝试使用外部视图来执行此操作,但是它的速度要慢得多,并且滞后很多。因此,我使用了回收站视图来解决此问题。
片段仅需8秒钟即可打开,而且非常缓慢。
任何出路还是替代方案?
这是我的片段代码:
public class GifFragment extends Fragment {
private View view;
RecyclerView rvMain;
public GifFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view=inflater.inflate(R.layout.fragment_gif,container,false);
rvMain = view.findViewById(R.id.rvMain);
int sticker[]={R.drawable.kitty1, R.drawable.kitty2, R.drawable.kitty3, R.drawable.kitty4, R.drawable.kitty5
, R.drawable.kitty6, R.drawable.kitty7, R.drawable.kitty8, R.drawable.kitty9, R.drawable.kitty10
, R.drawable.kitty11, R.drawable.kitty12, R.drawable.kitty13, R.drawable.kitty14, R.drawable.kitty15};
MyAdapter adapter = new MyAdapter(sticker);
rvMain.setLayoutManager(new GridLayoutManager(getContext(), 3));
adapter.setHasStableIds(true);
rvMain.setAdapter(adapter);
return view;
}
private class MyAdapter extends RecyclerView.Adapter<MyViewHolder> {
int sticker[];
public MyAdapter( int sticker[]) {
this.sticker=sticker;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_item, parent, false);
MyViewHolder viewHolder = new MyViewHolder(v);
return viewHolder;
}
@Override
public void onBindViewHolder(MyViewHolder holder, final int position) {
holder.logo.setImageResource(sticker[position]);
holder.logo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getActivity(), "This is: " , Toast.LENGTH_SHORT).show();
}
});
}
@Override
public int getItemCount() {
return sticker.length;
}
}
private class MyViewHolder extends RecyclerView.ViewHolder{
public ImageView logo;
public TextView name;
public MyViewHolder(View itemView) {
super(itemView);
logo = (ImageView)itemView.findViewById(R.id.ivLogo);
}
}
}
最佳答案
使用Glide可以有效地加载图像。
例
在应用模块gradle
中添加此
repositories {
mavenCentral()
google()
}
dependencies {
implementation 'com.github.bumptech.glide:glide:4.9.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
}
然后使用滑行从
drawable
加载图像Glide.with(this).load(R.drawable.image_name).into(imageView);
例
onBindViewHolder做到这一点
Glide.with(this).load(sticker[position]).into(holder.logo);
