如何去除Launcher默认的google search bar？
[SOLUTION]
JB2/JB3/JB5/JB9:
1. 请修改 Launcher2/res/layout/qsb_bar.xml，如下：
<include android:id="@+id/qsb_search_bar"
layout="@layout/search_bar"
android:visibility="gone" />
2. 请修改Launcher2/res/layout-port/launcher.xml，将voice_button_proxy这个view的clickable设置为false，并去掉onClick="onClickVoiceButton"，如下：
<com.android.launcher2.DrawableStateProxyView
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"
android:importantForAccessibility="no"
launcher:sourceViewId="@+id/voice_button" />
3. 请修改Launcher2/src/com/android/launcher2/SearchDropTargetBar.java的onFinishInflate() 方法，如下：
......
// Create the various fade animations
if (mEnableDropDownDropTargets) {
mDropTargetBar.setTranslationY(-mBarHeight);
mDropTargetBarAnim = ObjectAnimator.ofFloat(mDropTargetBar, "translationY",
-mBarHeight, 0f);
mQSBSearchBarAnim = ObjectAnimator.ofFloat(mQSBSearchBar, "translationY", -mBarHeight,
-mBarHeight);
} else {
mDropTargetBar.setAlpha(0f);
mDropTargetBarAnim = ObjectAnimator.ofFloat(mDropTargetBar, "alpha", 0f, 1f);
mQSBSearchBarAnim = ObjectAnimator.ofFloat(mQSBSearchBar, "alpha", 0f, 0f);
}
......
4. 请修改Launcher2/src/com/android/launcher2/SearchDropTargetBar.java的showSearchBar()方法，如下：
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);
}
}
mIsSearchBarHidden = false;
}
KK：
1. 请修改Launcher3/res/layout-port/search_bar.xml，如下：
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:launcher="http://schemas.android.com/apk/res-auto/com.android.launcher3"
style="@style/SearchDropTargetBar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/search_frame"
android:visibility="gone">
2. 请修改Launcher3/res/layout-port/launcher.xml，将voice_button_proxy这个view的clickable设置为false，并去掉onClick="onClickVoiceButton"，如下：
<com.android.launcher3.DrawableStateProxyView
android:id="@+id/voice_button_proxy"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_gravity="top|end"
android:clickable="false"
android:importantForAccessibility="no"
launcher:sourceViewId="@+id/voice_button" />
3. 请修改Launcher3/src/com/android/launcher3/SearchDropTargetBar.java的setup()方法，如下：
......
if (mEnableDropDownDropTargets) {
mQSBSearchBarAnim = ObjectAnimator.ofFloat(mQSBSearchBar, "translationY", -mBarHeight,
-mBarHeight);
} else {
mQSBSearchBarAnim = ObjectAnimator.ofFloat(mQSBSearchBar, "alpha", 0f, 0f);
}
......
4. 请修改Launcher3/src/com/android/launcher3/SearchDropTargetBar.java的showSearchBar()方法，如下：
public void showSearchBar(boolean animated) {
boolean needToCancelOngoingAnimation = mQSBSearchBarAnim.isRunning() && !animated;
if (!mIsSearchBarHidden && !needToCancelOngoingAnimation) return;
if (animated) {
prepareStartAnimation(mQSBSearchBar);
mQSBSearchBarAnim.reverse();
} else {
mQSBSearchBarAnim.cancel();
if (mEnableDropDownDropTargets) {
mQSBSearchBar.setTranslationY(0);
} else {
mQSBSearchBar.setAlpha(0f);
}
}
mIsSearchBarHidden = false;
}
5. 请修改Launcher3/src/com/android/launcher3/Workspace.java的getChangeStateAnimation()方法，如下：
......
float finalSearchBarAlpha = !stateIsNormal ? 0f : 0f;
