由于两个控件相似，实现功能也比较简单，就把他们写在一起了，直接上代码<1.xml布局文件><?xml version="1.0" encoding="utf-8"?><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:orientation="vertical"> <Button android:layout_width="match_parent" android:layout_height="60dp" android:text="点我显示日期" android:textSize="20.0sp" android:gravity="center" android:id="@+id/date" /> <Button android:layout_width="match_parent" android:layout_height="60dp" android:text="点我显示时间" android:textSize="20.0sp" android:gravity="center" android:id="@+id/time" /></LinearLayout><2.源代码>public class MainActivity extends AppCompatActivity implements View.OnClickListener{ PRivate DatePickerDialog datePickerDialog; private TimePickerDialog timePickerDialog; private Button data,time; private int year,month,date,hour,min; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); init(); data.setOnClickListener(this); time.setOnClickListener(this); } //实例化控件 private void init(){ data= (Button) findViewById(R.id.date); time= (Button) findViewById(R.id.time); } @Override public void onClick(View v) { switch (v.getId()){ case R.id.date: shoawdate(); break; case R.id.time: showTime(); break; } } private void shoawdate(){ //得到当前的年、月、日 year= Calendar.getInstance().get(Calendar.YEAR); month=Calendar.getInstance().get(Calendar.MONTH); date=Calendar.getInstance().get(Calendar.DAY_OF_MONTH); //把得到的当前年、月、日传过去 datePickerDialog=new DatePickerDialog(MainActivity.this,new dataDialog(),year,month,date); //别忘了要显示该Dialog，调用show(); datePickerDialog.show(); } //创建内部类实现日期组件接口 private class dataDialog implements DatePickerDialog.OnDateSetListener{ @Override public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { //把今天的日期显示在日期按钮上 data.setText(year+"年"+(monthOfYear+1)+"月"+dayOfMonth+"日"); } } private void showTime(){ //得到当前的时间，小时和分钟 hour=Calendar.getInstance().get(Calendar.HOUR_OF_DAY); min=Calendar.getInstance().get(Calendar.MINUTE); //把得到的当前小时、分钟传过去 timePickerDialog=new TimePickerDialog(MainActivity.this,new TimeDialog(),hour,min,false); //别忘了要显示该Dialog，调用show(); timePickerDialog.show(); } //创建内部类实现时间组件接口 private class TimeDialog implements TimePickerDialog.OnTimeSetListener{ @Override public void onTimeSet(TimePicker view, int hourOfDay, int minute) { //把现在的时间显示在时间按钮上 time.setText("现在的时间是"+hourOfDay+":"+minute); } }}基本代码就这些，希望对你有所帮助！
