如何在Fragment类中从公共静态void调用到非静态公共void

Question

如何在Fragment类中从公共静态void调用到非静态公共void？ 还是在（listViewHolder.dot.setOnClickListener（new View.OnClickListener（）和public void search3（））之间调用另一种方法

// Tab2 //公共类Tab2扩展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

如果要从OnClickListener调用Fragment或Activity方法，则必须将对该Fragment或Activity的引用存储在某个地方。 可能这样的事情将为您工作：

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();
            }
        });

        ...
    }
}

Answer 2

将公共类CustomAdapter扩展Tab2片段类内部的BaseAdapter扩展为这样，类CustomAdapter扩展BaseAdapter并移除静态
