您好frineds我想在我的应用程序屏幕中显示我的特定通知消息，所以下面是我的代码

mNotificationManager.notify(Integer.parseInt(intent.getExtras().get("NotifyCount").toString()), notification);
Toast.makeText(context, "New Notification Received", Toast.LENGTH_SHORT).show();
}
}
NotificationView.java
public class NotificationView extends Activity {
String title;
String text;
TextView txttitle;
TextView txttext;
String noti;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.notificationview);
Intent i = getIntent();
title = i.getStringExtra("Name");
text = i.getStringExtra("Description");
noti =i.getStringExtra("NotifyCount");
System.out.println("title "+title);
System.out.println("text "+text);
System.out.println("noti "+noti);
// Locate the TextView
txttitle = (TextView) findViewById(R.id.title);
txttext = (TextView) findViewById(R.id.text);
txttitle.setText("Title : "+title);
txttext.setText(Html.fromHtml("<b> Description :</b>"+" "+text) );
}
}
当我在上面运行代码时，第一次通知在我的 Notificationview.java 类中显示正确但是当我发出第二个通知并点击它时它会显示我做的第一个通知，它没有更新通知显示在 notificationview.java 课程中我知道如何解决它？
答案 0 :(得分：1)
在NotificationView类中实现override方法。
/**
* Method to decide which detail view should be called on the basis of
* notification when notification is clicked.
* @param intent
*/
public void onNewIntent(Intent intent) {
try {
Bundle extras = intent.getExtras();
if (extras != null) {
title = intent.getStringExtra("Name");
text = intent.getStringExtra("Description");
noti = intent.getStringExtra("NotifyCount");
// Locate the TextView
txttitle = (TextView) findViewById(R.id.title);
txttext = (TextView) findViewById(R.id.text);
txttitle.setText("Title : "+title);
txttext.setText(Html.fromHtml("<b> Description :</b>"+" "+text) );
}
} catch (Exception e) {
e.printStackTrace();
}
}
在onCreate方法中，请致电onNewIntent(getActivity().getIntent());
希望它有效。
