Question

spinner.getSelectedItemPosition(); spinner.getSelectedItem().toString(); 取不到所选的值?

spinner.setAdapter(aa);
tableRow.addView(spinner);
spinner.getSelectedItemPosition();
spinner.getSelectedItem().toString();

Answer 1

为下拉列表设置事件的响应，这个事响应菜单被选中
spinner.setOnItemSelectedListener(new Spinner.OnItemSelectedListener(){
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {

/* 将所选spinner 的值带入TextView 中*/
myTextView.setText("您选择的是："+ adapter.getItem(arg2));
/* 将mySpinner 显示*/
arg0.setVisibility(View.VISIBLE);
}
