如何创建一个baseactivity

 public class TypeInActivity extends BaseActivity {
     @Override
     public void setContentView() {
         setContentView(R.layout.activity_type_in_layout);
     }

     @Override
     public void findViews() {

     }

     @Override
     public void getData() {

     }

     @Override
     public void showConent() {
         showGuide( );
     }

     public void onClick( View v ){
         switch( v.getId( ) ){
         case R.id.searchBtnId:{

         }
         break;
         default:{

         }
         break;
         }
     }

     private void showGuide( ){
         new Thread( new Runnable( ) {
             @Override
             public void run() {
                 try {
                     Thread.sleep( 1000 );
                 } catch (InterruptedException e1) {
                     e1.printStackTrace();
                 }

                 // “旋转”的拼音
                 int[] keyCodeArray = new int[]{KeyEvent.KEYCODE_X,KeyEvent.KEYCODE_U,KeyEvent.KEYCODE_A,KeyEvent.KEYCODE_N,KeyEvent.KEYCODE_SPACE,KeyEvent.KEYCODE_Z,KeyEvent.KEYCODE_H,KeyEvent.KEYCODE_U,KeyEvent.KEYCODE_A,KeyEvent.KEYCODE_N};
                 for( int keycode : keyCodeArray ){
                     try {
                         typeIn( keycode );
                         Thread.sleep( 200 );
                     } catch (InterruptedException e) {
                         e.printStackTrace();
                     }
                 }
             }
         }).start( );
     }

     private void typeIn( final int KeyCode ){
         try {
             Instrumentation inst = new Instrumentation();
             inst.sendKeyDownUpSync( KeyCode );
         } catch (Exception e) {
             Log.e("Exception when sendKeyDownUpSync", e.toString());
         }
     }
 }

BaseActivity.java：（个人已经习惯这样写了。。。）

 public abstract class BaseActivity extends Activity {
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         init( );
     }

     private void init( ){
         setContentView( );
         findViews( );
         getData( );
         showConent( );
     }

     public abstract void setContentView( );
     public abstract void findViews( );
     public abstract void getData( );
     public abstract void showConent( );
 }
