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：
<?xml version="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>
