Android 按动按钮似乎不起作用
以下代码用于设置自定义通知。我已经设法设置了我的变量，如日期和时间选择器等，但我的按钮按下，使一切都开始似乎不起作用。我没有得到祝酒词，活动似乎要结束了 xml中的我的按钮Android 按动按钮似乎不起作用,android,button,notifications,Android,Button,Notifications,以下代码用于设置自定义通知。我已经设法设置了我的变量，如日期和时间选择器等，但我的按钮按下，使一切都开始似乎不起作用。我没有得到祝酒词，活动似乎要结束了 xml中的我的按钮 <Button android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_gravity="center_
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="center_horizontal"
android:id="@+id/button_set_notifications"
android:text="Set Your Notifications"
android:background="@color/green_A700"
android:textColor="@color/white"
android:padding="10dp"
android:textStyle="bold"
android:paddingBottom="16dp"
android:onClick="SetNotificationsButton"/>
更改方法语法，如下所示：
public void SetNotificationsButton(View view){
// Method must have View Object as parameter.
}
可能是重复的我做了你建议的改变，但仍然得到一个力量接近，没有祝酒词。我已将我的logcat添加到原始问题中。我删除了除toast之外的所有代码，您的解决方案至少允许我显示toast，因此强制关闭问题必须在我的代码中存在。非常感谢。
