推荐答案

您可以尝试将 onItemSelectedListener 设置为您的微调器:

You can try setting the onItemSelectedListener to your spinner:

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this, R.array.planets_array, android.R.layout.simple_spinner_item);   
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);   
spinner.setAdapter(adapter);

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

  @Override
  public void onItemSelected(AdapterView<?> arg0, View arg1,
          int arg2, long arg3) {
      startActivity(new Intent(Intent.ACTION_VIEW,
             Uri.parse("http://yoururl.com")));
  }

  @Override
  public void onNothingSelected(AdapterView<?> arg0) {}

});

这将使用您的网址打开浏览器.

This will open the browser with your url.
