android DatePicker和TimePicke用法

DatePicker和TimePicker都是从FrameLayout派生而来。

简单的例子实现对时间监听。

<?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:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="选择时间"
    />
    <DatePicker android:id="@+id/datepicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    />
    <TimePicker
    android:id="@+id/timepicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
       android:layout_gravity="center_horizontal"
    />
    <EditText
       android:id="@+id/et"
       android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:editable="false"
    android:cursorVisible="false"
    />

</LinearLayout>

                    int dayOfMonth) {
        TimeExampleActivity.this.year=year;
        TimeExampleActivity.this.month=monthOfYear;
        TimeExampleActivity.this.day=dayOfMonth;
        showDate(year,month,day,hour,minute);
            }

            @Override

    private void showDate(int year, int month, int day, int hour,int minute) {
        EditText et = (EditText) findViewById(R.id.et);
        et.setText(year+"年"+month+"月"+day+"日"+hour+"时"+minute+"分");
    }
