我的Android应用程序被传递信息的意图调用(状态栏中的pendingintent).

当我按下主页按钮并通过按住主页按钮重新打开我的应用程序时,它再次调用了意图,并且仍然存在相同的附加功能.

    @Override
    public void onSaveInstanceState(Bundle savedInstanceState) {
      super.onSaveInstanceState(savedInstanceState);
    }
    @Override
    public void onRestoreInstanceState(Bundle savedInstanceState) {
      super.onRestoreInstanceState(savedInstanceState);
    }

这是不像它应该运行的代码

    String imgUrl;
    Bundle extras = this.getIntent().getExtras();


    if(extras != null){
        imgUrl = extras.getString("imgUrl");
        if( !imgUrl.equals(textView01.getText().toString()) ){

            imageView.setImageDrawable( getImageFromUrl( imgUrl ) );
            layout1.setVisibility(0);
            textView01.setText(imgUrl);//textview to hold the url

        }

    }

我的意图是:

public void showNotification(String ticker, String title, String message, 
    String imgUrl){
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager mNotificationManager = 
        (NotificationManager) getSystemService(ns);
    int icon = R.drawable.icon;        // icon from resources
    long when = System.currentTimeMillis();         // …
