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. */@Overridepublic 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(); } }); }}?
