Android时间选择器的简单实现

一、概述

大家项目中可能都多多少少都要用到时间选择，今天写一个小demo,实现了这个功能，有需要的可以参考一下。

二、页面效果

三、实现过程（不多说，上代码）

public class MainActivity extends Activity implements OnTouchListener {

	private EditText et1;
	private EditText et2;
	private Context context = this;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		// requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.activity_main);
		// 初始化textview控件
		et1 = (EditText) findViewById(R.id.et1);
		et2 = (EditText) findViewById(R.id.et2);
		// 添加touch事件
		et1.setOnTouchListener(this);
		et2.setOnTouchListener(this);
	}

	@Override
	public boolean onTouch(View v, MotionEvent event) {
		if (event.getAction() == MotionEvent.ACTION_DOWN) {
			switch (v.getId()) {
			case R.id.et1:
				initDialog();
				break;

			case R.id.et2:
				initTimeDialog();
				break;
			}
		}

		return false;
	}

	/**
	 * 选择日期带时间
	 */
	private void initTimeDialog() {
		AlertDialog.Builder builder = new AlertDialog.Builder(context);
		View view = View.inflate(context, R.layout.date_time_dialog, null);
		builder.setView(view);
		builder.setTitle("请选择日期时间");
		final DatePicker datePicker = (DatePicker) view
				.findViewById(R.id.date_picker);
		final TimePicker timePicker = (TimePicker) view
				.findViewById(R.id.time_picker);

		Calendar calendar = Calendar.getInstance();
		calendar.setTimeInMillis(System.currentTimeMillis());
		datePicker.init(calendar.get(Calendar.YEAR),
				calendar.get(Calendar.MONTH),
				calendar.get(Calendar.DAY_OF_MONTH), null);

		timePicker.setIs24HourView(true);
		timePicker.setCurrentHour(calendar.get(Calendar.HOUR_OF_DAY));
		timePicker.setCurrentMinute(Calendar.MINUTE);
		// 设置确定按钮点击事件
		builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {

			@Override
			public void onClick(DialogInterface dialog, int which) {
				StringBuffer sb = new StringBuffer();
				//String格式化的使用
				sb.append(String.format("%d-%02d-%02d", datePicker.getYear(),
						datePicker.getMonth() + 1, datePicker.getDayOfMonth()));
				sb.append("  ");
				//String格式化的使用,这个很好用
				sb.append(String.format("%02d:%02d",
						timePicker.getCurrentHour(),
						timePicker.getCurrentMinute()));
				et2.setText(sb);
				dialog.cancel();

			}
		});
		// 设置取消点击事件
		builder.setNegativeButton("取消", new OnClickListener() {

			@Override
			public void onClick(DialogInterface dialog, int which) {
				dialog.cancel();
			}
		});
		
		AlertDialog dialog = builder.create();
		dialog.show();
	}

	/**
	 * 加载日期选择dialog
	 * 
	 * @param layoutId
	 */
	private void initDialog() {
		AlertDialog.Builder builder = new AlertDialog.Builder(context);
		View view = View.inflate(context, R.layout.date_dialog, null);
		builder.setView(view);
		// 初始化时间选择控件
		final DatePicker datePicker = (DatePicker) view
				.findViewById(R.id.dp_date_picker);
		Calendar calendar = Calendar.getInstance();
		calendar.setTimeInMillis(System.currentTimeMillis());
		datePicker.init(calendar.get(Calendar.YEAR),
				calendar.get(Calendar.MONTH),
				calendar.get(Calendar.DAY_OF_MONTH), null);
		builder.setTitle("请选择日期");
		builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {

			@Override
			public void onClick(DialogInterface dialog, int which) {
				StringBuffer sb = new StringBuffer();
				sb.append(String.format("%d-%02d-%02d", datePicker.getYear(),
						datePicker.getMonth() + 1, datePicker.getDayOfMonth()));

				et1.setText(sb);
				dialog.cancel();
			}
		});
		builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {

			@Override
			public void onClick(DialogInterface dialog, int which) {
				// TODO Auto-generated method stub
				dialog.cancel();
			}
		});
		AlertDialog dialog = builder.create();
		dialog.show();
	}

}
