我在soundcloud服务器上传音频但是当我点击上传按钮时它会抛出FileNotFoundException。从服务器上传响应后必须生成.plss帮助我们。如果我在某处犯错误，请纠正我。
有2种情况，其中执行上传功能。 1.只记录一页故事音频并将其强化（在这种情况下音频正在上传）。 2.录制多个页面故事，其中在上传第一页音频后，第二页将作为我服务器的响应。（在这种情况下，它抛出FileNotFound异常）。

在您的Activity类
中添加此代码@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
ArrayList<String> names = new ArrayList<>();
ArrayList<Integer> types = new ArrayList<>();
//add item to manes and types array
ListViewAdapter customList = new ListViewAdapter(this, names, types);
list = (ListView) findViewById(R.id.lv);
list.setAdapter(customList);
}
这是ListViewAdapter类
public class ListViewAdapter extends ArrayAdapter<String> {
private ArrayList<String> names;
ArrayList<Integer> types;
private Activity context;
public ListViewAdapter(Activity context, ArrayList<String> names, ArrayList<Integer> types) {
super(context, R.layout.item_rating_rows, names);
this.context = context;
this.names = names;
this.types = types;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.item_rating_rows, null, true);
Button btn = (Button) listViewItem.findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Log.d("__onclick", "" + view.getId());
}
});
return listViewItem;
}
}
