android – 是否可以从对话框中调用onReceive方法？_app

概述我有一个带editText和保存按钮的自定义对话框.单击按钮时,我希望它调用MyReceiver.但是MyReceiver中的日志和Toast永远不会显示出来. 提醒 final AlertDialog.Builder builder = new AlertDialog.Builder(this); LayoutInflater inflater = LayoutI 我有一个带editText和保存按钮的自定义对话框.单击按钮时,我希望它调用MyReceiver.但是MyReceiver中的日志和Toast永远不会显示出来.

提醒

final AlertDialog.Builder builder = new AlertDialog.Builder(this);                LayoutInflater inflater = LayoutInflater.from(this);                VIEw promptVIEw = getLayoutInflater().inflate(R.layout.dialog_with_edittext,null);                button save = (button) promptVIEw.findVIEwByID(R.ID.okBtn);                final EditText task = (EditText) promptVIEw.findVIEwByID(R.ID.task);                time = (EditText) promptVIEw.findVIEwByID(R.ID.time);                date = (EditText) promptVIEw.findVIEwByID(R.ID.date);                final AlertDialog alert = builder.create();                date.setonClickListener(this);                save.setonClickListener(new VIEw.OnClickListener() {                    public voID onClick(VIEw v) {                        String addTask= task.getText().toString();                        String time1= time.getText().toString();                        String date1= date.getText().toString();                        if (adapter != null) {                            adapter.add(addTask,time1,date1);                            insertTask(addTask,date1);                            ListvIEw.setAdapter(adapter);                            alert.dismiss();                            check();                        }                        c.set(Calendar.YEAR,year1);                        c.set(Calendar.MONTH,month1);                        c.set(Calendar.DAY_OF_MONTH,day1);                        c.set(Calendar.HOUR_OF_DAY,hour1);                        c.set(Calendar.MINUTE,min1);                        c.set(Calendar.SECOND,0);                        c.set(Calendar.AM_PM,Calendar.AM);                        Toast.makeText(getApplicationContext(),year1+""+month1+""+day1+"",Toast.LENGTH_SHORT).show();                        Toast.makeText(getApplicationContext(),hour1+""+min1+"",Toast.LENGTH_SHORT).show();                        Intent myIntent = new Intent(ReminderPage.this,MyReceiver.class);                        pendingIntent = PendingIntent.getbroadcast(ReminderPage.this,123456789,myIntent,0);                        AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);                        alarmManager.set(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),pendingIntent);                        Toast.makeText(getApplicationContext(),"Alarm",Toast.LENGTH_SHORT).show();                }                });                alert.setVIEw(promptVIEw);                alert.show();                return true;

MyReceiver

public class MyReceiver extends broadcastReceiver{    @OverrIDe    public voID onReceive(Context context,Intent intent)    {        Log.i("App","called receiver method");        try{            Toast.makeText(context,"Call Utils1",Toast.LENGTH_SHORT).show();            Utils1.generateNotification(context);        }catch(Exception e){            Toast.makeText(context,"Not Call Utils1",Toast.LENGTH_SHORT).show();            e.printstacktrace();        }    }}

我还在AndroIDMainfest中添加了这个

<receiver androID:name="com.example.MyReceiver"></receiver>

Utils1

public class Utils1 {        public static notificationmanager mManager;        @SuppressWarnings("static-access")        public static voID generateNotification(Context context){            mManager = (notificationmanager) context.getSystemService(context.NOTIFICATION_SERVICE);            Intent intent1 = new Intent(context,Register.class);            PendingIntent pendingIntent = PendingIntent.getActivity(context,1,intent1,0);            Notification.Builder builder = new Notification.Builder(context);            builder.setautoCancel(false);            builder.setTicker("this is ticker text");            builder.setContentTitle("WhatsApp Notification");            builder.setContentText("You have a new message");            builder.setSmallicon(R.drawable.done);            builder.setContentIntent(pendingIntent);            builder.setongoing(true);            builder.setSubText("This is subtext...");   //API level 16            builder.setNumber(100);            builder.build();            Notification myNotication = builder.getNotification();            mManager.notify(0,myNotication);        }    }

任何帮助将不胜感激.

解决方法根据您的问题,以下步骤将为您提供您想要的确切内容.

1.)在AndroIDManifest.xml中替换你的接收器

<receiver androID:name="com.example.MyReceiver"></receiver>

通过以下方式：

<receiver androID:name=".MyReceiver" />

2.)最后在你的代码中添加这个按钮监听器：

save.setonClickListener(new VIEw.OnClickListener() {    public voID onClick(VIEw v) {        // ...        getApplicationContext().sendbroadcast(                new Intent(getApplicationContext(),MyReceiver.class));        // ...    }});

就是这样,现在运行你的应用程序.每当您单击保存按钮时,您会注意到MyReceiver类中的onReceive()方法将被正确调用.这意味着你的logcat输出将是
