今天完成了闹钟提醒板块，采用学习了同学的模板思路

首先是工具类，commonuntil类

package com.example.a86191.timeword;

import android.app.AlertDialog;
import android.content.Context;
import android.widget.Toast;

import java.text.SimpleDateFormat;
import java.util.Date;

/*
 *自定义的通用工具类
 */
public class Commonutil {

    /*
     *显示短消息
     */
    public static void showShortMsg(Context context, String msg){
        Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();
    }

    /*
     *显示长消息
     */
    public static void showLongMsg(Context context, String msg){
        Toast.makeText(context, msg, Toast.LENGTH_LONG).show();
    }

    /*
     *显示消息对话框
     */
    public static void showDigMsg(Context context, String msg){
        new AlertDialog.Builder(context)
                .setTitle("提示信息")
                .setMessage(msg)
                .setPositiveButton("确定",null)
                .setNegativeButton("取消",null)
                .create().show();
    }

    public static String getNowDate(){
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        return sdf.format(new Date());

    }
}

然后是提醒后的alarmactivity类，此类主要通过此文件进行弹窗提示内容，xml文件由于弹窗遮挡的原因所有不需要进行太多装饰

package com.example.a86191.timeword;




import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import com.example.a86191.timeword.Commonutil;


public class AlarmActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Bundle bundle = getIntent().getExtras();
        String thing = bundle.getString("thing");
        AlertDialog alert = new AlertDialog.Builder(this).create();
        alert.setTitle("到时间了！");
        alert.setMessage(thing);
        alert.setButton(DialogInterface.BUTTON_POSITIVE, "确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {

            }
        });
        alert.show();
    }
}

这里alarm类的xml文件我们便不进行添加了，下面是clockactivity

package com.example.a86191.timeword;



import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.EditText;
import android.widget.TimePicker;
import com.example.a86191.timeword.Commonutil;

import java.util.Calendar;

public class ClockActivity extends AppCompatActivity implements View.OnClickListener {

    private TimePicker timePicker;
    private EditText et_thing;
    private String thing;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_clock);
        //获取时间拾取组件
        timePicker = (TimePicker) findViewById(R.id.time1 );
//        timePicker.setIs24HourView(true);   //设置24小时制
        findViewById(R.id.btn_set).setOnClickListener(this);
        et_thing = findViewById(R.id.et_thing);
    }

    @RequiresApi(api = Build.VERSION_CODES.M)
    @Override
    public void onClick(View view) {
        //设置闹钟
        thing = et_thing.getText().toString().trim();
        Intent intent = new Intent(ClockActivity.this,AlarmActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("thing",thing);
        intent.putExtras(bundle);
        PendingIntent pendingIntent;


        pendingIntent = PendingIntent.getActivity(ClockActivity.this, 0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
        AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        Calendar c = Calendar.getInstance();
        //获取在时间拾取器中设置的小时和分钟并给予日历对象
        c.set(Calendar.HOUR_OF_DAY,timePicker.getHour());
        c.set(Calendar.MINUTE,timePicker.getMinute());
        c.set(Calendar.SECOND,0);
        alarm.set(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),pendingIntent);
        Commonutil.showShortMsg(ClockActivity.this,"提醒设置成功！");

    }
}

clock的xml文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="5dp">

    <TimePicker
        android:id="@+id/time1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <EditText
        android:id="@+id/et_thing"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="请输入待提醒的事宜"/>

    <Button
        android:id="@+id/btn_set"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

</LinearLayout>
