如何去除launcher 上默认的 google search bar.

MT6515/75/17/77 Android ICS/ICS2请参考如下改法：
1: Launcher2\res\layout\qsb_bar.xml中，

<include android:id="@+id/qsb_search_bar"

         layout="@layout/search_bar"

         android:visibility="gone" />　//加入 android:visibility="gone"

 
2: Launcher2\src\com\android\launcher2\SearchDropTargetBar.java 中

onFinishInflate() 方法内，将mQSBSearchBarFadeInAnim相关的部分作如下修改：

 mQSBSearchBarFadeInAnim = ObjectAnimator.ofFloat(mQSBSearchBar, "alpha", 0f); //最后一个参数改为 0f, 原来是 1f

         mQSBSearchBarFadeInAnim.setDuration(sTransitionInDuration);

         mQSBSearchBarFadeInAnim.addListener(new AnimatorListenerAdapter() {

             @Override

             public void onAnimationStart(Animator animation) {

                 mQSBSearchBar.setVisibility(View.INVISIBLE); //参数改为 View.INVISIBLE, 原来是 View.VISIBLE

 
3: 仍然是此 java 文件，将showSearchBar() 方法作如下修改：

public void showSearchBar(boolean animated) {

              if (LauncherLog.DEBUG) LauncherLog.d(TAG, "(SearchDropTargetBar)showSearchBar animated = " + animated);

         cancelAnimations();

         if (animated) {

             mQSBSearchBarFadeInAnim.start();

         } else {

             mQSBSearchBar.setVisibility(View.INVISIBLE); //参数改为：View.INVISIBLE

             mQSBSearchBar.setAlpha(0f); //参数改为 0f.

         }

         mIsSearchBarHidden = false;

     }

             }

         });

1: Launcher2\res\layout\qsb_bar.xml中，

<include android:id="@+id/qsb_search_bar"
         layout="@layout/search_bar"
         android:visibility="gone" />　//加入 android:visibility="gone"

 
2: Launcher2\src\com\android\launcher2\SearchDropTargetBar.java 中

onFinishInflate() 方法内，将mQSBSearchBarAnim 相关的部分作如下修改：
 // Create the various fade animations
         if (mEnableDropDownDropTargets) {
             mDropTargetBar.setTranslationY(-mBarHeight);
             mDropTargetBarAnim = ObjectAnimator.ofFloat(mDropTargetBar, "translationY",
                     -mBarHeight, 0f);
             mQSBSearchBarAnim = ObjectAnimator.ofFloat(mQSBSearchBar, "translationY",-mBarHeight,
                     -mBarHeight); //modify 3rd para to -mBarHeight
         } else {
             mDropTargetBar.setAlpha(0f);
             mDropTargetBarAnim = ObjectAnimator.ofFloat(mDropTargetBar, "alpha", 0f, 1f);
             mQSBSearchBarAnim = ObjectAnimator.ofFloat(mQSBSearchBar, "alpha", 0f, 0f); //modify 3rd para to 0f;
         }

 
3: 仍然是这只 java 文件，将showSearchBar 方法作如下修改：

public void showSearchBar(boolean animated) {
         if (!mIsSearchBarHidden) return;
         if (animated) {
             prepareStartAnimation(mQSBSearchBar);
             mQSBSearchBarAnim.reverse();
         } else {
             mQSBSearchBarAnim.cancel();
             if (mEnableDropDownDropTargets) {
                 mQSBSearchBar.setTranslationY(0);
             } else {
                 mQSBSearchBar.setAlpha(0f); //参数改为 0f;
             }
         }
         mIsSearchBarHidden = false;
     }
