第一步：在MainActivity的代码：

package com.example.yangjian.learncomponents;import android.app.DatePickerDialog;import android.support.v7.app.ActionBarActivity;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.widget.Button;import android.widget.DatePicker;public class chooseADate extends ActionBarActivity {    private Button btnChooseDate;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_choose_adate);        btnChooseDate = (Button) findViewById(R.id.btnChooseDate);        btnChooseDate.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                new DatePickerDialog(chooseADate.this, new DatePickerDialog.OnDateSetListener() {                    @Override                    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {                        String thedate = String.format("%d-%d-%d", monthOfYear+1, dayOfMonth);                        System.out.println(thedate);                        btnChooseDate.setText(thedate);                    }                },2015,8,3).show();            }        });    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.menu_choose_adate, menu);        return true;    }    @Override    public boolean onOptionsItemSelected(MenuItem item) {        // Handle action bar item clicks here. The action bar will        // automatically handle clicks on the Home/Up button, so long        // as you specify a parent activity in AndroidManifest.xml.        int id = item.getItemId();        //noinspection SimplifiableIfStatement        if (id == R.id.action_settings) {            return true;        }        return super.onOptionsItemSelected(item);    }}

第二步：在xml文件中的代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:paddingBottom="@dimen/activity_vertical_margin"    android:orientation="vertical"    tools:context="com.example.yangjian.learncomponents.chooseADate">    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="0000-00-00"        android:id="@+id/btnChooseDate"/></LinearLayout>
