问题描述

此代码将字符串从列表添加到微调器.
如何实现侦听器，以便可以从微调框中单击或点击字符串?

This code adds strings to a Spinner from a list.
How do I implement a listener so that I can get the string that is clicked or tapped from the Spinner?

spinner = (Spinner) findViewById(R.id.spinner);
List<String> list = new ArrayList<String>();

ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, list);
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    spinner.setAdapter(dataAdapter);

推荐答案

您可以使用此代码

 spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) 
    {
        String selectedItem = parent.getItemAtPosition(position).toString(); //this is your selected item
    }
    public void onNothingSelected(AdapterView<?> parent) 
    {

    }           
});
