用按钮代替Spinner，弹出的对话框，截图和代码请见附件！

用spinner实现对话框

public class SpinnerUseInArea extends Activity {
	Spinner mySpinner;
	private static final String[] countriesStr = { "111", "222", "333", "444" };

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		mySpinner = (Spinner) findViewById(R.id.mySpinner);

		ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
				android.R.layout.simple_spinner_item, countriesStr);
		adapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
		mySpinner.setAdapter(adapter);

	}
}

用按钮实现

public class EX03_12 extends Activity 
{
  private Button mButton1;
  
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) 
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    mButton1 = (Button) findViewById(R.id.myButton1);
    mButton1.setOnClickListener(new OnClickListener()
    {
      
      public void onClick(View v)
      {
        new AlertDialog.Builder(EX03_12.this)
       // .setTitle("niaho")
        .setItems(R.array.select_dialog_items, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {

                /* User clicked so do some stuff */
               /* String[] items = getResources().getStringArray(R.array.select_dialog_items);
                new AlertDialog.Builder(EX03_12.this)
                        .setMessage("You selected: " + which + " , " + items[which])
                        .show();*/
            }
        }).show();
        
        
      }
    });
  }
}

  有些手机可以获取本身的sim号码，有些手机是获取不到的，htc1.5能获取  在1.6版本上就获取不到了，不过打至方法一样，

public class TestShowNum extends Activity {
    /** Called when the activity is first created. */
	TextView textView;
	Button button;
	  String tel;
	  String deviceid ;
	  String imei;
	  String imsi;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        button=(Button) findViewById(R.id.butto);
        textView=(TextView) findViewById(R.id.text);
    	TelephonyManager tm = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
        deviceid = tm.getDeviceId();

        tel = tm.getLine1Number();

      imei = tm.getSimSerialNumber();

       imsi = tm.getSubscriberId();
        button.setOnClickListener(new OnClickListener() {
			
			public void onClick(View v) {
				// TODO Auto-generated method stub
				textView.setText(deviceid+"\n"+tel+"\n"+"\n"+imei+"\n"+imsi);
			}
		});
    }
}

 在AndroidManifest.xml中加上

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
