我想要做的是以下
IntentService在后台调用来处理Receiver班上我的代码到目前为止如下:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
if(IsRepository){
view = vi.inflate(R.layout.filerepositorylayout, null);
}
}
BindLayoutElemnts(view, position);
return view;
}

这是调用Intent服务的地方:
private void BindLayoutElemnts(View view, int position) {
myFiles = (files) getItem(position);
img_Download.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getContext(),DownloadService.class);
intent.putExtra("FileID",""+myFiles.getID());
intent.putExtra("FileName",myFiles.getName());
context.startService(intent);
}
