多个Activity共用相同布局或者相同控件

1.多个Activity共用相同布局或者相同控件：避免重复代码;

BaseActivit代码：

public  class  BaseActivity  extends  Activity  implements  OnClickListener
{
    /*
     * 多个Activity共用相同布局或者相同控件
     * 写个基类继承，避免重复代码
     */
    @Override
    public  void  onClick(View v)
    {
        switch  (v.getId())
        {
        case  R.id.common_titlebar_btn_back:
            finish();
            break ;
        default :
            break ;
        }
        baseOnClick(v);
    }

    protected  void  baseOnClick(View v)
    {

    }

    @Override
    protected  void  onCreate(Bundle savedInstanceState)
    {
        super .onCreate(savedInstanceState);
//        setContentView(R.layout.activity_base);
    }

    @Override
    protected  void  onResume()
    {
        super .onResume();
        onPostOnCreate();
    }

    public  final  void  onPostOnCreate() //find同一个控件
    {
        findViewById(R.id.common_titlebar_btn_back).setOnClickListener( this );
    }
    @Override
    public  boolean  onCreateOptionsMenu(Menu menu)
    {
        getMenuInflater().inflate(R.menu.base, menu);
        return  true ;
    }
}

子类代码：

public  class  ThirdActivity  extends  BaseActivity
{
    /**
     *  layout里复用同一布局：
     *     <include
     *   android:id="@+id/include1"
     *   layout="@layout/common_titlebar" />
     */
    @Override
    protected  void  onCreate(Bundle savedInstanceState)
    {
        super .onCreate(savedInstanceState);
        setContentView(R.layout.activity_third_main);
    }
}
