在android中打开已打开的活动
原标题:Open an already opened Activity in android

我正在开发一个应用程序及其主屏幕小工具。

现在,从我的小部件中,当我按下一个按钮时,它会从原来的位置打开我的应用程序。

意味着如果我在应用程序运行期间按下主页按钮,那么我的应用程序将进入后台模式。

现在我想它应该恢复我打开的应用程序。

每当我按下小工具中的按钮时。我该怎么做??

请帮忙

提前感谢大家!

问题回答

我以前从未制作过小部件,但这就是我在下拉栏并单击它时将通知启动回原始活动的方式。

Intent originalActivity = new Intent(getApplicationContext(), Widget.class);
originalActivity.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

再说一次,不确定如何使用小部件,但为了重新启动它以获得通知,您可以将该Intent转换为PendingIntent,以便稍后在您想重新启动时调用。我认为这与在小部件上使用它的方式类似。
