Question

我正在尝试在我的应用中使用NotificationCompat.Builder类。以下代码在ICS手机上运行得非常好，但不是姜饼。根据我的理解，支持库是否允许从低至API级别4的手机访问Builder？我做了一些根本错误的事情吗？

public class MainActivity extends Activity implements OnClickListener {
NotificationCompat.Builder builder;
NotificationManager nm;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        builder = new NotificationCompat.Builder(this);
        nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        builder.setContentTitle("Test Notification")
        .setContentText("This is just a test notification")
        .setTicker("you have been notified")
        .setSmallIcon(R.drawable.ic_stat_example)
        .setWhen(System.currentTimeMillis());

        findViewById(R.id.btn_notify).setOnClickListener(this);
    }

    public void onClick(View arg0) {
        // TODO Auto-generated method stub
        if(arg0.getId() == R.id.btn_notify){
        nm.notify(1, builder.build());
        }
    }
}

您必须提供在单击通知时将触发的Intent。否则，通知将不会显示在Gingerbread上。如果您不想在单击通知时启动活动，则只需传递一个空的Intent，如下所示。

Intent intent = new Intent();
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, Intent.FLAG_ACTIVITY_NEW_TASK);

builder.setContentTitle("Test Notification")
    .setContentText("This is just a test notification")
    .setTicker("you have been notified")
    .setSmallIcon(R.drawable.ic_stat_example)
    .setWhen(System.currentTimeMillis())
    .setContentIntent(pendingIntent); // add this

NotificationCompat.Builder无法使用Gingerbread
