Android --时间控件的使用

1. mian.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/LL"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TimePicker
        android:id="@+id/timePicker1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </TimePicker>

</LinearLayout>

2. 12 小时

  TimePicker timePicker=(TimePicker)findViewById(R.id.timePicker1);        //获取对象
        timePicker.setCurrentHour(8);                                    //设置小时
        timePicker.setCurrentMinute(12);                                //设置分钟

3. 24 小时

 TimePicker timePicker=(TimePicker)findViewById(R.id.timePicker1);        //获取对象
        timePicker.setCurrentHour(15);                                    //设置小时
        timePicker.setCurrentMinute(12);                                //设置分钟
        timePicker.setIs24HourView(true);                                //设置24小时制显示

4.显示时间

 TimePicker timePicker=(TimePicker)findViewById(R.id.timePicker1);
        timePicker.setCurrentHour(15);
        timePicker.setCurrentMinute(12);
        timePicker.setIs24HourView(true);
        timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {

            @Override
            public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
                // TODO Auto-generated method stub
                Toast.makeText(getApplicationContext(), "当前时间为："+hourOfDay+"点"+minute+"分",
                        Toast.LENGTH_LONG).show();                    //显示时间信息

            }
        });

5.判断是否是24小时制 根据结果进行显示

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"
    android:id="@+id/LL">
    <TimePicker
        android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/timePicker1">
    </TimePicker>
    <Button
        android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/button1"
        android:text="@string/btn1">
    </Button>
</LinearLayout>

firstActivity

 Button bt1=(Button)findViewById(R.id.button1);                            //获取按钮对象
        final TimePicker timePicker=(TimePicker)findViewById(R.id.timePicker1);        //获取TimePicker对象
        timePicker.setCurrentHour(15);                                        //设置小时
        timePicker.setCurrentMinute(12);                                    //设置分钟

        bt1.setOnClickListener(new View.OnClickListener() {                        //设置按钮监听器

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                int hour,minite;
                boolean is24v;
                hour=timePicker.getCurrentHour();                            //获取显示小时
                minite=timePicker.getCurrentMinute();                        //获取显示分钟
                is24v=timePicker.is24HourView();                            //获取是否为24小时制
                if(is24v)                                                //24小时制的情况
                {
                    Toast.makeText(getApplicationContext(), "当前时间为："+hour+"小时"+minite+"分钟",
                        Toast.LENGTH_LONG).show();                    //显示时间信息
                }
                else                                                    //上午/下午模式
                {
                    if (hour<12)
                    {
                     Toast.makeText(getApplicationContext(), "当前时间为：上午"+hour+"小时"+minite+"分钟",
                                Toast.LENGTH_LONG).show();            //显示时间信息
                    }
                    else
                    {
                     Toast.makeText(getApplicationContext(),"当前时间为：下午"+(hour-12)+"小时"+minite+"分钟",
                                Toast.LENGTH_LONG).show();            //显示时间信息
                    }
                }
            }
        });
