【问题描述】：

我创建了一个推送通知的按钮，但我希望此通知在 10 秒后出现。怎么做？这是我的 MainActivity

import android.app.Notification;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;

public class MainActivity extends AppCompatActivity {
    private NotificationManagerCompat notificationManager;
    private EditText editTextTitle;
    private EditText editTextMessage;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        notificationManager= NotificationManagerCompat.from(this);
        editTextTitle = findViewById(R.id.editTxtTitle);
        editTextMessage = findViewById(R.id.editTxtMessage);
    }
    public void sendOnChannel(View view){
        String title = editTextTitle.getText().toString();
        String message = editTextMessage.getText().toString();
        Notification notification = new NotificationCompat.Builder(this,CHANNEL_1_ID)
                .setSmallIcon(R.drawable.ic_one).setContentTitle(title).setContentText(message)
                .setCategory(NotificationCompat.CATEGORY_MESSAGE).build();
        notificationManager.notify(1, notification);
    }
}

我认为你需要延迟，试试看这个，例如：stackoverflow.com/questions/42379301/…

【解决方案1】：

您可以使用所有View 项目的postDelayed 方法来实现这一点：

public void sendOnChannel(View view){
    String title = editTextTitle.getText().toString();
    String message = editTextMessage.getText().toString();
    Notification notification = new NotificationCompat.Builder(this, CHANNEL_1_ID)
            .setSmallIcon(R.drawable.ic_one).setContentTitle(title).setContentText(message)
            .setCategory(NotificationCompat.CATEGORY_MESSAGE).build();
    
    view.postDelayed(new Runnable() {
        @Override
        public void run() {
            notificationManager.notify(1, notification);
        }
    }, 10 * 1000);
}
