问题描述
写android级联时，报错。Caused by: java.lang.RuntimeException: setOnItemClickListener cannot be used with a spinner.oid
代码如下：sp_college.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Overridepublic void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { arrayAdapter=new ArrayAdapter<CharSequence>(MainActivity.this,android.R.layout.simple_spinner_item,college[i]); sp_college.setAdapter(arrayAdapter);} });
问题解答
回答1：spinnerView.setOnItemSelectedListener( new OnItemSelectedListener() {public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { showToast('Spinner1: position=' position ' id=' id);} public void onNothingSelected(AdapterView<?> parent) { showToast('Spinner1: unselected');} });希望对你有用回答2：
用setOnItemSelectedListener可以吧
