VOID：同一按钮上调用了静态和非静态

Question

I have button, onclick="weboscio".

I want to do two things on click:

public void web(View view) {
    Intent intent = new Intent(this, about.class);
    startActivity(intent); 
    //opens a new layout

And also:

 public static void warning(Context context, int id, int titleResId, int textResId, PendingIntent intent) {

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    String title = context.getString(titleResId);   
    ....etc....
    // to open a pop-up window

Just put there two voids into one activity and call it on button click. I searched quite a lot, but nothing useful.. I also tried:

public static void weboscio(String args[]) {
        home something = new something();
        something.web();
        new something().warning();

It obviously works only for non-static voids.. and also I were getting an error in .web(HERE) and .warning(HERE).

weboscio = onclick function

home = main java activity

web = activity supposed to open new layout

warning = activity supposed to display some warning on new layout

Ok, after looking at the problem again, I understand what's going on. You're simply calling the static method incorrectly.

Do this instead:

public static void weboscio(String args[]) {
    home something = new something();
    something.web();
    home.warning(...);

A static method is called through the class, not the instance of the class.

Here's an example:

String x = new String("Hello");
x.concat("World"); // non-static

String y = String.join("Hello", "World"); // static
