主界面添加事件：
1 public class DateTimePickerActivity extends Activity { 2 /** Called when the activity is first created. */ 3 private EditText DateTime; 4 5 6 private String initDateTime = "2013年9月3日 14:44"; // 初始化开始时间 7 8 9 @Override 10 public void onCreate(Bundle savedInstanceState) { 11 super.onCreate(savedInstanceState); 12 setContentView(R.layout.activity_main); 13 14 DateTime = (EditText) findViewById(R.id.inputDate); 15 16 17 DateTime.setText(initDateTime); 18 19 DateTime.setOnClickListener(new OnClickListener() { 20 public void onClick(View v) { 21 22 DateTimePickDialogUtil dateTimePicKDialog = new DateTimePickDialogUtil( 23 DateTimePickerActivity.this, initDateTime); 24 dateTimePicKDialog.dateTimePicKDialog(DateTime); 25 26 } 27 }); 28 29 } 30 }
