[英]How to programmatically eliminate space occupied by SearchView hint icon in SearchView
[英]Removing AppBar SearchView Hint Icon
我正在嘗試刪除應用欄搜索視圖提示中的圖標。
所以我想刪除searchView中的放大鏡。
我是安卓的初學者。
這是我的主要活動布局
<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"

tools:openDrawer="start">
<include
layout="@layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
...
</androidx.drawerlayout.widget.DrawerLayout>
這是 app_bar_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
app:srcCompat="@android:drawable/ic_dialog_email" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
這是我的 main.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/search"
android:title="Recherche"
android:icon="@drawable/ic_search"
app:showAsAction="ifRoom"
app:actionViewClass="android.widget.SearchView"/>
</menu>
這是我的 searchable.xml
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="@string/app_name"
android:hint="@string/search_hint"
android:voiceSearchMode="showVoiceSearchButton|launchRecognizer"
/>

}
我不知道我應該編輯什么來刪除這個圖標
感謝您的回答
編輯:如果對你來說更容易,這里是 github https://github.com/BenoitBonavia/geoloc-indoor-application
找到了 ! 在我的 activity.java 的 onCreateOptionsMenu 方法中,我添加了這個:
int magId = getResources().getIdentifier("android:id/search_mag_icon", null, null);
ImageView magImage = searchView.findViewById(magId);
magImage.setLayoutParams(new LinearLayout.LayoutParams(0, 0));
