@Override
public boolean onOptionsItemSelected(MenuItem item) {       
RelativeLayout screen = (RelativeLayout) findViewById(R.id.RelativeLayout01);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    switch (item.getItemId()) {
    case R.id.menu_control: {
    inflater.inflate(R.layout.adv_video, screen, true);
    adapter = new ArrayAdapter<String>(screen.getContext(), R.id.spinner1, new String[]{"Author","ISBN","Keyword","Title"});
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
spinner = (Spinner) screen.findViewById(R.id.spinner1);
spinner.setAdapter(adapter);

进一步在代码按钮、编辑文本等中。如果评论spinner.setAdapter(adapter);- 一切正常，带有空微调器列表。

这是日志：

您可以设置( )的 id ，而不是提供要使用的布局文件的 id。实例化应该是这样的：ArrayAdapterSpinnerR.id.spinner1ArrayAdapter

adapter = new ArrayAdapter<String>(screen.getContext(), android.R.layout.simple_spinner_item, new String[]{"Author","ISBN","Keyword","Title"});

或者提供id另一个布局文件（R.layout.layout_file_name），它只包含一个TextView.
