有谁知道如何在谷歌提供的代码中使用“mId”变量？
http://developer.android.com/guide/topics/ui/notifiers/notifications.html
文档中没有解释。但出现在代码的最后一行。使用此代码时，它是未定义的，因此我必须将其定义为“private int mId;”
完全失去了这个。我得到这个的代码如下所示。
mNotificationManager.notify(mId, mBuilder.build());
ButtonOne.setOnClickListener(new View.OnClickListener() {
private int mId;
// anonymous inner class override for on click
public void onClick(View v) {
Intent myIntent = new Intent(MainActivity.this, CoverFlowExample.class);
MainActivity.this.startActivity(myIntent);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(MainActivity.this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("My notification")
.setContentText("Hello World!");
// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(MainActivity.this, MainActivity.class);
// The stack builder object will contain an artificial back stack for the
// started Activity.
// This ensures that navigating backward from the Activity leads out of
// your application to the Home screen.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(MainActivity.this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(MainActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(mId, mBuilder.build());
}
});
