android - Android 上的通知管理器问题

Question

我正在尝试使用按钮进行通知，但 Notification 和 setLatestEventInfo 均已弃用。

两个错误:

1. 构造函数 Notification(int, CharSequence, long) 被弃用 Notification notify = new Notification(android.R.drawable.stat_notify_more, "Hello all", System.currentTimeMillis());

2.Notification类型的方法setLatestEventInfo(Context, CharSequence, CharSequence, PendingIntent)不适用于参数(Context, CharSequence, CharSequence, Intent) notify.setLatestEventInfo(上下文、标题、详细信息、 Intent )；

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Button b = (Button) findViewById(R.id.button1);
    b.setOnClickListener(new View.OnClickListener() {   
        @Override
        public void onClick(View v) {
            NotificationManager ns = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            Notification notify = new Notification(android.R.drawable.stat_notify_more, "Hello all", System.currentTimeMillis());
            Context context = MainActivity.this;
            CharSequence title ="you have be notified";
            CharSequence details = "Continue your work";
            Intent intent = new Intent(context,MainActivity.class);
            PendingIntent pending = PendingIntent.getActivity(context, 0, intent, 0);
            notify.setLatestEventInfo(context, title, details, intent);
            ns.notify(0,notify);


        }
    });
}

API 级别:

       android:minSdkVersion="11"
       android:targetSdkVersion="17"

有什么选择？

Answer 1

<强>1。该构造函数在 API 级别 11 中已弃用。因此您应该使用 Notification.Builder。

例如

Notification notification = new Notification.Builder(mContext)
     .setContentTitle("New mail from " + sender.toString())
     .setContentText(subject)
     .setSmallIcon(R.drawable.new_mail)
     .setLargeIcon(aBitmap)
     .build();

<强>2。在您的代码中，您正在传递 Intent 而不是在 setLatestEventInfo 中挂起

....
Intent intent = new Intent(context,MainActivity.class);
        PendingIntent pending = PendingIntent.getActivity(context, 0, intent, 0);
        notify.setLatestEventInfo(context, title, details, pending);
        ns.notify(0,notify);
....
