本文介绍了一个简单的Android应用，该应用使用TimePickerDialog组件让用户能够选择时间。通过MainActivity类的定义，展示了如何创建按钮并设置监听器以弹出时间选择对话框。

MainActivity.java

package com.fzq.timepicker;

import com.fzq.timepicker.R.id;

import android.R.integer;
import android.app.Activity;
import android.app.Dialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TimePicker;

public class MainActivity extends Activity {
	private Button timePicker;
	private static final int  Time_Pick_ID=1;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		timePicker=(Button)findViewById(R.id.timePicker);
		timePicker.setOnClickListener(new timePickerListener());
	}
	class timePickerListener implements OnClickListener{

		@Override
		public void onClick(View v) {
			// TODO Auto-generated method stub
			showDialog(Time_Pick_ID);
			
		}
		
	}
	
	TimePickerDialog.OnTimeSetListener onTimeSetListener=new  TimePickerDialog.OnTimeSetListener(){

		@Override
		public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
			// TODO Auto-generated method stub
			System.out.print("时间:"+hourOfDay+" :"+minute);
			
		}
		
	};
	
	
	protected Dialog onCreateDialog(int Id){
		switch (Id) {
		case Time_Pick_ID:
			
			//false 是表示不以24小时方式显示时间
			return new TimePickerDialog(MainActivity.this, onTimeSetListener, 11,26, false);
			
		

		
		}
		return null;
		
	}
}

Main.xml
