请参考如下改法：
1. Launcher2 eslayoutqsb_bar.xml中，
layout=@layout/search_bar
android:visibility=gone />//加入 android:visibility=gone
2. Launcher2srccomandroidlauncher2SearchDropTargetBar.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;
}
}
});
JB:
1. Launcher2 eslayoutqsb_bar.xml中，
layout=@layout/search_bar
android:visibility=gone />//加入 android:visibility=gone
2. packagesappsLauncher2 eslayout-portlauncher.xml
android:id=@+id/voice_button_proxy
android:layout_width=80dp
android:layout_height=@dimen/qsb_bar_height
android:layout_gravity=top|right
android:clickable=false //modify this value to false
onClick=onClickVoiceButton
android:importantForAccessibility=no
launcher:sourceViewId=@+id/voice_button />.android.launcher2.drawablestateproxyview
3. Launcher2srccomandroidlauncher2SearchDropTargetBar.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;
}
4. 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;
}
