如何在Fragment类中从public static void调用非静态public void

Question

如何在Fragment类中从public static void调用非静态public void？ 或者是否有另一种方法来调用（listViewHolder.dot.setOnClickListener（new View.OnClickListener（）和public void search3（））

    // Tab2     //公共类Tab2扩展了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");

        }
    });

Answer 1

如果您想从Fragment调用Activity或OnClickListener方法，则必须在某处存储对Fragment或Activity的引用。可能这样的事情对你有用：

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();
            }
        });

        ...
    }
}

把公共类CustomAdapter像这样在tab2 Fragment类中扩展BaseAdapter class CustomAdapter扩展BaseAdapter并删除静态
