android AlarmManager闹钟设置多次只响应一次和响应多次以及传参的实现

在开发中，遇到设置闹钟但是遇到设置多次结果只响应一次，查阅好多资料终于解决了，现在把解决的方法分享一下，其次就是如果传参的问题，也一并贴出来供大家参考
代码如下：

import android.app.AlarmManager;import android.app.PendingIntent;import android.content.Context;import android.content.Intent;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.util.Log;import android.view.View;import android.widget.Button;public class AlamActivity extends AppCompatActivity implements View.OnClickListener{    private Button only_btn;    private Button repeat_btn;    private AlarmManager mAlarmManager;    public static int currentIntent=0;    public static int alarmCount=0;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        init();    }    private void init(){        only_btn =(Button)findViewById(R.id.btn_open);        repeat_btn=(Button)findViewById(R.id.btn_close);        only_btn.setOnClickListener(this);        repeat_btn.setOnClickListener(this);        only_btn.setText("Only");        repeat_btn.setText("Repeat");        mAlarmManager=(AlarmManager)getSystemService(Context.ALARM_SERVICE);    }    @Override    public void onClick(View v) {        switch (v.getId()){            case R.id.btn_open:                Log.e("MainActivity","only");                onlyShow();                break;            case R.id.btn_close:                Log.e("MainActivity","repeat");                repeatShow();                break;        }    }  //只响应一次    private void onlyShow(){        long date1 = System.currentTimeMillis();        Log.e("MainActivity","only闹钟开启时间为:"+date1);        Intent intent =new Intent(this, AlarmBroadCast.class);        PendingIntent pi = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);        mAlarmManager.setExact(AlarmManager.RTC_WAKEUP, date1+30000, pi);    } //只响应多次    private void repeatShow(){        long date1 = System.currentTimeMillis();        Log.e("MainActivity","repeat闹钟开启时间为:"+date1);        Intent intent =new Intent(this, AlarmBroadCast.class);        intent.putExtra("date",date1+"");        PendingIntent pi = PendingIntent.getBroadcast(this, alarmCount++, intent,currentIntent++ + PendingIntent.FLAG_UPDATE_CURRENT);//第四个参数区别每次注册的闹钟 第二个参数区别每次传递的参数        mAlarmManager.setExact(AlarmManager.RTC_WAKEUP, date1+30000, pi);    }}

广播类的代码：

import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.util.Log;import android.widget.Toast;import java.text.SimpleDateFormat;import java.util.Date;public class AlarmBroadCast extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:SSS");        String date = simpleDateFormat.format(new Date());        String value = intent.getStringExtra("date");        Log.e("MainActivity","闹钟时间为:"+date+"----参数为："+value);        Toast.makeText(context,date,Toast.LENGTH_SHORT).show();    }}
