解决方案

只需拨打您的按钮侦听以下内容：

  spinnerFolder.getOnItemSelectedListener（）onItemSelected（spinnerFolder，spinnerFolder.getSelectedView（），spinnerFolder.getSelectedItemPosition（），spinnderFolder.getSelectedItemId（））;

I have a spinner control with setOnItemSelectedListener in my app, when I select an item of the spinner, the event onItemSelected will be launched.Now I hope to click a button to launch the onItemSelected event, how can I do? Thanks!

spinnerFolder.setOnItemSelectedListener(new OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,int arg2, long arg3) {
                //Do Business Logic
            }           
            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
            }   
        });

解决方案

Just call the following from your button listener:

spinnerFolder.getOnItemSelectedListener().onItemSelected(spinnerFolder, spinnerFolder.getSelectedView(), spinnerFolder.getSelectedItemPosition(), spinnderFolder.getSelectedItemId());

That's all :-)
