我创建了一个像gallery这样的android应用程序，其中包含一些使用gridview片段的图像。
我的应用程序功能正常，并且图像显示在片段gridview中，并且当我单击项目时我的第二个活动也打开了，但是当我的图像未加载或加载完成需要时间时，我想显示带有进度条的加载图像。 / p>
我也想在gridview中显示图像计数。
但是我想在加载图像上显示进度条：WANT LINK THIS SCREENSHOT
我的gridview看起来像这样：My gridview looks like this
已找到 这是我的应用程序片段代码：
public class CallFragment extends Fragment {
GridView grid;
String[] plan = {
"Student Bundle",
"SMS Plus Bundle",
"Instagram",
"Facebook",
"Flickr"
} ;
String[] web = {
"*3000",
"*106*1",
"Instagram",
"Facebook",
"Flickr"
} ;
int[] imageId = {
R.drawable.calla,
R.drawable.smsb,
R.drawable.person7,
R.drawable.person7,
R.drawable.person7
};
int[] fullimg = {
R.drawable.callaa,
R.drawable.smsbb,
R.drawable.person7,
R.drawable.person7,
R.drawable.person7
};
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setHasOptionsMenu(true);
View view = inflater.inflate(R.layout.fragment_call,container,false);
CustomGrid adapter = new CustomGrid(getActivity(), plan, web, imageId, fullimg);
grid=(GridView) view.findViewById(R.id.grid);
grid.setAdapter(adapter);
grid.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
String value=(String)grid.getItemAtPosition(i);
Intent intent=new Intent(getActivity(),Book.class);
intent.putExtra("web", web[i]);
intent.putExtra("plan", plan[i]);
intent.putExtra("imageId", imageId[i]);
intent.putExtra("fullimg", fullimg[i]);
startActivity(intent);
}
});
return view;
}
这是我的应用程序CustomAdapter代码：
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.MyViewHolder> {
ArrayList<String> personNames;
ArrayList<String> personCode;
ArrayList<Integer> personImages;
ArrayList<Integer> personImages1;
Context context;
public CustomAdapter(Context context, ArrayList<String> personNames, ArrayList<String> personCode, ArrayList<Integer> personImages, ArrayList<Integer> personImages1) {
this.context = context;
this.personCode = personCode;
this.personNames = personNames;
this.personImages = personImages;
this.personImages1 = personImages1;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// infalte the item Layout
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.rowlayout, parent, false);
// set the view's size, margins, paddings and layout parameters
MyViewHolder vh = new MyViewHolder(v); // pass the view to View Holder
return vh;
}
@Override
public void onBindViewHolder(MyViewHolder holder, final int position) {
// set the data in items
//holder.name.setText(personNames.get(position));
holder.image.setImageResource(personImages.get(position));
//holder.image.setImageResource(personImages1.get(position));
// implement setOnClickListener event on item view.
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// open another activity on item click
Intent intent = new Intent(context, SecondActivity.class);
//intent.putExtra("image", personImages.get(position)); // put image data in Intent
intent.putExtra("name", personNames.get(position)); // put image data in Intent
intent.putExtra("code", personCode.get(position)); // put image data in Intent
intent.putExtra("image", personImages1.get(position)); // put image data in Intent
context.startActivity(intent); // start Intent
}
});
}
@Override
public int getItemCount() {
return personNames.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder {
// init the item view's
TextView name;
TextView code;
ImageView image;
public MyViewHolder(View itemView) {
super(itemView);
// get the reference of item view's
name = (TextView) itemView.findViewById(R.id.name);
code = (TextView) itemView.findViewById(R.id.code);
image = (ImageView) itemView.findViewById(R.id.image);
}
}
}
另外，如果更容易使用默认图像代替加载图像而不是进度条也可以。
请提供给我解决方案以实施此操作。 我希望您能得到我想要的要点，谢谢您的帮助。
