Android – 如何从微调框中获取所选项目值并将其放入字符串？

@Override
protected void onCreate(Bundle savedInstanceStatE) {
    super.onCreate(savedInstanceStatE);
    setContentView(R.layout.activity_main);

    Spinner spinner = (Spinner) findViewById(R.id.imc_spinner);
    // Create an ArrayAdapter using the String array and a default spinner layout
    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromresource(this,R.array.imc_array,@R_674_1061@t.simple_spinner_item);
    // Specify the layout to use when the list of choices appears
    adapter.setDropDownViewresource(@R_674_1061@t.simple_spinner_dropdown_item);
    // Apply the adapter to the spinner
    spinner.setAdapter(adapter);

}

public void onItemSELEcted(AdapterView<?> parent,View view,int pos,long id) {
    // An item was SELEcted. You can retrieve the SELEcted item using

    imc_met = parent.getItemAtPosition(pos).toString();

}

我声明imc_met为public String imc_met ;.问题是imc_met不包含微调框的选定项目的值,但它为空…

问题在哪里？

提前Thx.

解决方法

spin.setOnItemSELEctedListener(new OnItemSELEctedListener() {

            @Override
            public void onItemSELEcted(AdapterView<?> arg0,View arg1,int arg2,long arg3) {
                String imc_met=spin.getSELEctedItem().toString();

            }

            @Override
            public void onNothingSELEcted(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });
