选择时间日历控件DatePickerDialog实现(从外包项目中挖出来整理的)

直接上源码

Mainactivity.java

package cn.xiayiye.canclder;

import java.util.Calendar;

import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {
	private int mYear;
	private int mMonth;
	private int mDay;
	static final int DATE_DIALOG_ID = 0;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		Button bt = (Button) findViewById(R.id.bt);
		mDayStr = (TextView) findViewById(R.id.id_day);
		bt.setOnClickListener(new OnClickListener() {

			@SuppressWarnings("deprecation")
			@Override
			public void onClick(View v) {
				// 获得当前时间
				final Calendar c = Calendar.getInstance();
				mYear = c.get(Calendar.YEAR);
				mMonth = c.get(Calendar.MONTH);
				mDay = c.get(Calendar.DAY_OF_MONTH);
				showDialog(DATE_DIALOG_ID);
				Toast.makeText(getApplicationContext(), "显示日历了",
						Toast.LENGTH_LONG).show();
			}
		});
	}

	@Override
	protected Dialog onCreateDialog(int id) {
		switch (id) {
		case DATE_DIALOG_ID:
			return new DatePickerDialog(this, mDateSetListener, mYear, mMonth,
					mDay);
		}
		return null;
	}

	private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {

		public void onDateSet(DatePicker view, int year, int monthOfYear,
				int dayOfMonth) {
			mYear = year;
			mMonth = monthOfYear;
			mDay = dayOfMonth;
			updateDisplay();
		}
	};
	private TextView mDayStr;

	// updates the date we display in the TextView
	private void updateDisplay() {
		mDayStr.setText(new StringBuilder()
				// Month is 0 based so add 1
				.append(mYear).append("-").append(mMonth + 1).append("-")
				.append(mDay).append(" "));
	}

}
