How can call from public static void to not static public void in Fragment class

Question

How to call from public static void to not static public void in Fragment class? Or is there another way to call between (listViewHolder.dot.setOnClickListener(new View.OnClickListener() and public void search3() )

// Tab2 // public class Tab2 extends Fragment

public void search3() {

Toast.makeText( getActivity(),"search3333333: " ,Toast.LENGTH_SHORT ).show();

}

public static void search4 (Context context1,String text) {

Toast.makeText( context1,text,Toast.LENGTH_LONG ).show();

Tab2 someClass = new Tab2();

someClass.search3();

}
//CustomAdapter 
//public class CustomAdapter extends BaseAdapter

    listViewHolder.dot.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

Toast.makeText( context,"" +  ff.getText().toString() ,Toast.LENGTH_LONG).show();

Tab2.search4(context,"hi hhhh");

        }
    });

What's wrong with your picture? It's _technically_ valid, but are you wanting to use a previous instance that was made? — Rogue, Jun 13 '17 at 13:52
thanks for the help But it's invalid , When come to someClass.search3(); give error and closes the Activity — TARIQ ALEED, Jun 13 '17 at 14:32
Tab2 is a fragment right? You cannot use `getActivity()` inside `search3()` method unless you commit the fragment to the activity. — Hussain, Jun 13 '17 at 15:33

If you want to call Fragment or Activity method from your OnClickListener, you have to store a reference to that Fragment or Activity somewhere. Probably something like this will work for you:

public class CustomAdapter extends BaseAdapter {
    private final Tab2 tab2;
    // other fields

    public CustomAdapter(Tab2 tab2, /* other constructor params ... */ ) {
        this.tab2 = tab2;
        // process other params and other initialization
    }

    ...
    @Override
    public View getView (int position, View convertView, ViewGroup parent) {

        ...

        listViewHolder.dot.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                tab2.search3();
            }
        });

        ...
    }
}

Tariq, your solution is essentially the same as mine but provides less flexibility. When you put `CustomAdapter` class inside `Tab2` class i.e. make it non-static `inner class` or `nested class`, compiler implicitly adds `tab2` argument to the constructor of `CustomAdapter` and adds it as an argument to the corresponding calls. See [Nested Classes](https://docs.oracle.com/javase/tutorial/java/javaOO/nested.html) for some details. – SergGr Jun 14 '17 at 17:08
