这里写图片描述

附上代码：

Mainactivity：

package com.example.dialog1;import android.app.Activity;import android.app.DatePickerDialog;import android.app.TimePickerDialog;import android.app.TimePickerDialog.OnTimeSetListener;import android.app.DatePickerDialog.OnDateSetListener;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.widget.Button;import android.widget.DatePicker;import android.widget.TimePicker;import android.widget.Toast;public class MainActivity extends Activity {    private Button bt;    private boolean flag=false;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initViews();    }    private void initViews() {        // TODO Auto-generated method stub        bt = (Button) findViewById(R.id.bt);    }    public void myclick(View v) {        TimePickerDialog tpd=new TimePickerDialog(this, new OnTimeSetListener() {            @Override            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {                // TODO Auto-generated method stub                flag=!flag;                if(flag)                Toast.makeText(MainActivity.this, "你选择的时间是："+hourOfDay+" : "+minute, 1000).show();            }        }, 17, 04, true);        tpd.setTitle("时间：");        tpd.setIcon(R.drawable.ic_launcher);        tpd.setMessage("请设置时间：");        tpd.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.main, 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();        if (id == R.id.action_settings) {            return true;        }        return super.onOptionsItemSelected(item);    }}

xml：

<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.example.dialog1.MainActivity" >    <Button        android:id="@+id/bt"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:text="shijian"       android:onClick="myclick"        /></RelativeLayout>
