我通过使用windowmanager AddView在应用程序中自定义通知。

InboxNotificationManager.java

public class InboxNotificationManager {
private static InboxNotificationManager instance;
private WindowManager mWindowManager;
private WindowManager.LayoutParams mWindowParams;
private InboxNotificationView notificationView;
private Runnable runnable;
private Handler handler = new Handler(Looper.getMainLooper());
private Animation.AnimationListener animationListener = new Animation.AnimationListener() {
    @Override
    public void onAnimationStart(Animation animation) {

    }

    @Override
    public void onAnimationEnd(Animation animation) {
        hideInboxNotification();

    }

    @Override
    public void onAnimationRepeat(Animation animation) {

    }
};


public static InboxNotificationManager Instance(Context context) {
    if (instance == null) {
        instance = new InboxNotificationManager(context);
    }
    return instance;

}

public InboxNotificationManager(Context context) {
    notificationView = new InboxNotificationView(context);
    mWindowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    mWindowParams = new WindowManager.LayoutParams();
    mWindowParams.gravity = Gravity.TOP | Gravity.RIGHT;
    mWindowParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
    mWindowParams.width = WindowManager.LayoutParams.MATCH_PARENT;
    mWindowParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
            | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH;
    mWindowParams.format = PixelFormat.TRANSLUCENT;
    runnable = new Runnable() {
        @Override
        public void run() {
            notificationView.stopAnimation(animationListener);

        }
    };


}

public void setTextMeesage(String meesage) {
    notificationView.setTextMessage(meesage);
    //  Toast.makeText(InboxNotificationManager.this, "", Toast.LENGTH_SHORT).show();


}

public void showInboxNotification(String message) {
    if (notificationView.getWindowToken() == null) {
        mWindowManager.addView(notificationView, mWindowParams);
        notificationView.startAnimation();
        setTextMeesage(message);

    } else {
        // mWindowManager.setText(count);

    }
    notificationView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            notificationView.stopAnimation(animationListener);

        }
    });

    handler.removeCallbacks(runnable);
    handler.postDelayed(runnable, 3000);


}

public void hideInboxNotification() {
    if (notificationView.getWindowToken() != null) {
        mWindowManager.removeView(notificationView);
    }


}

当我使用这个类时

InboxNotificationManager.Instance(BaseActivity.this).showInboxNotification("Hello world");

谢谢你，抱歉我的英语不好。

确保您的活动正在运行，请使用

if(mActivity != null && !mActivity.isFinishing())
