Android Studio（5）

1、日期选择器：java部分代码：

<DatePicker    android:id="@+id/datapicker"    android:layout_width="match_parent"    android:layout_height="match_parent"></DatePicker>

获取日期java部分代码：

package com.example.lenovo.android;

import android.app.Activity;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.RadioGroup;
import android.widget.Toast;

import java.util.Calendar;


public class MainActivity extends Activity {
    int year,month,day;
    DatePicker datePicker;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        datePicker=(DatePicker)findViewById(R.id.datapicker);
        Calendar calendar=Calendar.getInstance();
        year=calendar.get(Calendar.YEAR);
        month=calendar.get(Calendar.MONTH);
        day=calendar.get(Calendar.DAY_OF_MONTH);
        datePicker.init(year,month,day,new DatePicker.OnDateChangedListener(){
            @Override
            public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                MainActivity.this.year=year;
                MainActivity.this.month=monthOfYear;
                MainActivity.this.day=dayOfMonth;
                show(year,monthOfYear,dayOfMonth);
            }
        });

    }

    private void show(int year,int month,int day){
        String str=year+"年"+(month+1)+"月"+day+"日";
        Toast.makeText(MainActivity.this,str,Toast.LENGTH_LONG).show();
    }
} 

 

 2、时间选择器：

<TimePicker    android:id="@+id/timepick"    android:layout_width="wrap_content"    android:layout_height="wrap_content"></TimePicker>获取时间的java代码与上面相似
