选择微调器项目时显示吐司

Question

我创造了一个微调器。选择一个项目后，我想显示一个toast，它将显示所选内容。我怎么能这样做？

Answer 1

试试这段代码。它对我来说很好用：

    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) {
        }
   });
