android中的timepick控件简单实用

Android在3.0后提工了时间/日期控件.这里只对时间控件(TimePick)做出简单的介绍.

如果想在项目中直接显示或者在项目中由用户自己选择,在布局文件中代码如下:

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.tianfeng.timepicker.MainActivity">    <TimePicker        android:id="@+id/timepicker"        android:layout_width="wrap_content"        android:layout_height="wrap_content"/>    <Button        android:id="@+id/btn_time"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/timepick"        android:layout_below="@+id/timepicker" /></RelativeLayout>

在mainactivity中,加载这些控件.代码如下.这里的button是为了让用户选择时间.

public class MainActivity extends AppCompatActivity implements View.OnClickListener {    private Button mBtnTime;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initView();    }    private void initView() {        mBtnTime = (Button) findViewById(R.id.btn_time);        mBtnTime.setOnClickListener(this);    }    @Override    public void onClick(View view) {        int id = view.getId();        switch(id){            case R.id.btn_time:                TimePickerFragment  timePicker = new TimePickerFragment();                timePicker.show(getFragmentManager(), "timePicker");                break;            default:                break;        }    }}

最后,我们还的有一个TimepickFragment类.来获取timepick对象

public class TimePickerFragment extends DialogFragment implements        TimePickerDialog.OnTimeSetListener {    @Override    public Dialog onCreateDialog(Bundle savedInstanceState) {        final Calendar calendar = Calendar.getInstance();        int hour = calendar.get(Calendar.HOUR_OF_DAY);        int minute = calendar.get(Calendar.MINUTE);        return new TimePickerDialog(getActivity(), this, hour, minute,                DateFormat.is24HourFormat(getActivity()));    }    @Override    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {        //处理设置的时间，这里我们作为示例，在日志中输出我们选择的时间        Log.d("onTimeSet", "hourOfDay: "+hourOfDay + "Minute: "+minute);    }

注意:calender导报早java.util.calender包.
