Eu quero escrever código uma vez e usar em diferentes atividades. Eu criei umBase Activity class por isso . Além disso, o cabeçalho de todos os layouts em diferentes atividades é o mesmo. Eu fiz isso com a ajuda do<include layout > tag.

Agora o problema é meuBaseActivity código não está sendo executado. Estou tentando fazer isso pela primeira vez se não tiver muita ideia sobre isso.

1.) O código da BaseActivity está abaixo:

package com.waheguru.app;

import android.R.integer;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

import android.view.View;
import android.view.View.OnClickListener;

import android.widget.Button;
import android.widget.Toast;

public abstract class BaseActivityMenu extends Activity {
    //action id
    private static final int ID_UP     = 1;
    private static final int ID_DOWN   = 2;
    private static final int ID_SEARCH = 3;
    private static final int ID_INFO   = 4;
    private static final int ID_ERASE  = 5; 
    private static final int ID_OK     = 6;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.header);

        ActionItem nextItem     = new ActionItem(ID_DOWN, "Book", getResources().getDrawable(R.drawable.menu_down_arrow));
        ActionItem prevItem     = new ActionItem(ID_UP, "Bookmark", getResources().getDrawable(R.drawable.menu_up_arrow));
        ActionItem searchItem   = new ActionItem(ID_SEARCH, "Find", getResources().getDrawable(R.drawable.menu_search));
        ActionItem infoItem     = new ActionItem(ID_INFO, "Info", getResources().getDrawable(R.drawable.menu_info));
        ActionItem eraseItem    = new ActionItem(ID_ERASE, "Clear", getResources().getDrawable(R.drawable.menu_eraser));
        ActionItem okItem       = new ActionItem(ID_OK, "OK", getResources().getDrawable(R.drawable.menu_ok));

        //use setSticky(true) to disable QuickAction dialog being dismissed after an item is clicked
        prevItem.setSticky(true);
        nextItem.setSticky(true);

        //create QuickAction. Use QuickAction.VERTICAL or QuickAction.HORIZONTAL param to define layout 
        //orientation
        final QuickAction quickAction = new QuickAction(this, QuickAction.VERTICAL);

        //add action items into QuickAction
        quickAction.addActionItem(nextItem);
        quickAction.addActionItem(prevItem);
        quickAction.addActionItem(searchItem);
        quickAction.addActionItem(infoItem);
        quickAction.addActionItem(eraseItem);
        quickAction.addActionItem(okItem);

        //Set listener for action item clicked
        quickAction.setOnActionItemClickListener(new QuickAction.OnActionItemClickListener() {          
            public void onItemClick(QuickAction source, int pos, int actionId) {                
                ActionItem actionItem = quickAction.getActionItem(pos);

                //here we can filter which action item was clicked with pos or actionId parameter
                if (actionId == ID_SEARCH) {
                    Toast.makeText(getApplicationContext(), "Let's do some search action", Toast.LENGTH_SHORT).show();
                } else if (actionId == ID_INFO) {
                    Toast.makeText(getApplicationContext(), "I have no info this time", Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(getApplicationContext(), actionItem.getTitle() + " selected", Toast.LENGTH_SHORT).show();
                }
            }
        });

        //set listnener for on dismiss event, this listener will be called only if QuickAction dialog was dismissed
        //by clicking the area outside the dialog.
        quickAction.setOnDismissListener(new QuickAction.OnDismissListener() {          
            public void onDismiss() {
                Toast.makeText(getApplicationContext(), "Dismissed", Toast.LENGTH_SHORT).show();
            }
        });
        Button books=(Button)findViewById(R.id.book);
        books.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                Intent intent=new Intent(ExampleActivity.this,List_of_books.class);
                startActivityForResult(intent, 0);
            }
        });
        //show on btn1
        Button btn1 = (Button) this.findViewById(R.id.menu);
        btn1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                quickAction.show(v);
            }
        });
    }
}

2.) A Atividade estendeu a Atividade Base

package com.waheguru.app;

import android.app.Activity;
import android.os.Bundle;

public class ABCActivity extends BaseActivityMenu  {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.home);
    }
}

Então alguém pode me ajudar onde eu estou fazendo algo errado.
