[英]How can i pass a function as a parameter to another function in android?
[英]How can I pass view as parameter in android?
我想每天在我的Android應用程序中創建通知。 為此,我做了一個createNotification
方法。 現在,我想在特定時間調用該方法。 我的mainactivity.java
如下:
package com.example.shiza.dailyquranquote;
import android.content.Intent;
import android.content.SharedPreferences;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import java.util.Calendar;
import java.util.Date;
public class MainActivity extends ActionBarActivity {
Date startDate= new Date("03/31/2015 12:00:00");
Date endDate = new Date();
TextView textView ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView)findViewById(R.id.verse);
long startDay = startDate.getTime() / 1000 / 60 / 60 / 24;
long endDay = endDate.getTime() / 1000 / 60 / 60 / 24;
long daysBetween = endDay - startDay;
SharedPreferences sharedPreferences = getSharedPreferences("QuranVerse",0);
String id = ""+ (daysBetween % 365) ;
String verse = sharedPreferences.getString(id, "");
if (verse == null)
{
verse ="Sufficient is Allah for me; There is no power except Him; And in Him I put my trust.";
}
Calendar rightNow = Calendar.getInstance();
textView.setText(verse + "current hour is" + rightNow.HOUR_OF_DAY);
if ( rightNow.HOUR_OF_DAY == 11 )
{
createNotification();
}
}
public void goToInsertVerse(View v)
{
Intent intent = new Intent(this,InsertVerse.class);
startActivity(intent);
}
public void goToGetVerse(View v)
{
Intent intent = new Intent(this,GetVerse.class);
startActivity(intent);
}
public void createNotification(View view) {
// Prepare intent which is triggered if the
// notification is selected
Intent intent = new Intent(this, MainActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
// Build notification
// Actions are just fake
Notification noti = new Notification.Builder(this)
.setContentTitle("New mail from " + "test@gmail.com")
.setContentText("Subject").setSmallIcon(R.drawable.background)
.setContentIntent(pIntent)
.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// hide the notification after its selected
noti.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, noti);
}
}
現在,我需要將view作為參數傳遞給createNotification
。 我做不到。 我該如何實現?
用戶setContent方法將“ RemoteViews ”作為參數
