Answer 2

试试看看这个代码。这对我来说很好：

Spinner spinnerone = (Spinner) findViewById(R.id.spinner); 
    ArrayAdapter<String> adapterone = new ArrayAdapter<String> (this,android.R.layout.simple_spinner_item,mtype2); 
    spinnerone.setAdapter(adapterone); 
    spinnerone.setSelection(0); 
    spinnerone.setOnItemSelectedListener(new OnItemSelectedListener() 
    { 
     public void onItemSelected(AdapterView<?> arg0, View arg1,int arg2, long arg3) 
     { 
      int item = spinnerone.getSelectedItemPosition(); 
      y = mtype2[item]; 
      Toast.makeText(getApplicationContext(), y, Toast.LENGTH_SHORT).show(); 
     } 
     public void onNothingSelected(AdapterView<?> arg0) { 
     } 
    });
