本文实例分析了Android开发之TimePicker控件用法。分享给大家供大家参考，具体如下：
新建项目：
New Android Project->
Project name:HelloSpinner
Build Target:Android 2.2
Application name:HelloSpinner
Package name:com.b510
Create Activity:MainActivity
Min SDK Version:9
Finish
运行效果：
如果：
return new TimePickerDialog(this, mTimeSetListener, mHour, mMinute, false);
代码部分：
MainActivity.java：
package com.b510; import java.util.Calendar; import android.app.Activity; import android.app.Dialog; import android.app.TimePickerDialog; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; import android.widget.TimePicker; public class HelloTimePicker extends Activity { /* 显示时间信息 */ private TextView tvTimePickerDisplay; /* 设置时间按钮 */ private Button btnTimePicker; /* 小时 */ private int mHour; /* 分钟 */ private int mMinute; /* 标识 dialog的id */ static final int TIME_DIALOG_ID = 0; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); this.tvTimePickerDisplay = (TextView) this .findViewById(R.id.tv_timepicker_display); this.btnTimePicker = (Button) findViewById(R.id.btn_timepicker); btnTimePicker.setOnClickListener(listener); // get the current time final Calendar c = Calendar.getInstance(); mHour = c.get(Calendar.HOUR_OF_DAY); mMinute = c.get(Calendar.MINUTE); // display the current date updateDisplay(); } private OnClickListener listener = new OnClickListener() { @Override public void onClick(View v) { showDialog(TIME_DIALOG_ID); } }; // updates the time we display in the TextView private void updateDisplay() { tvTimePickerDisplay.setText(new StringBuilder().append(pad(mHour)).append(":") .append(pad(mMinute))); } private static String pad(int c) { if (c >= 10) return String.valueOf(c); else return "0" + String.valueOf(c); } // the callback received when the user "sets" the time in the dialog private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() { public void onTimeSet(TimePicker view, int hourOfDay, int minute) { mHour = hourOfDay; mMinute = minute; updateDisplay(); } }; @Override protected Dialog onCreateDialog(int id) { switch (id) { case TIME_DIALOG_ID: return new TimePickerDialog(this, mTimeSetListener, mHour, mMinute, true); } return null; } }
main.xml：
<"1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:id="@+id/tv_timepicker_display" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <Button android:id="@+id/btn_timepicker" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Change the time" /> </LinearLayout>
希望本文所述对大家Android程序设计有所帮助。
