如何删除 SearchView 删除图标

Question

This is the EDIT image: it shows the space i want to remove; 我正在搜索我的应用程序。我似乎无法删除“SearchView”图标。

这是 XML：

   <?xml version="1.0" encoding="utf-8"?>
  <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:background="#e9eaea"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:padding="0dp"
tools:context="com.echo.isaac.echo_simplyawesome.Search">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="0dp"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        app:popupTheme="@style/AppTheme.PopupOverlay"
        android:background="@color/colorPrimary"
        android:contentInsetStart="0dp"
        android:contentInsetLeft="0dp"
        app:contentInsetStart="0dp"
        app:contentInsetLeft="0dp"
        tools:targetApi="lollipop">

            <SearchView
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:id="@+id/searchView"
                android:queryHint="@string/search"
                android:iconifiedByDefault="false"
                android:paddingLeft="-16dp"
                android:paddingStart="-16dp"
                android:theme="@style/SearchViewStyle"
                android:background="@drawable/input_background_teal"
                android:queryBackground="@drawable/input_background_teal"
                tools:targetApi="lollipop_mr1" />

    </android.support.v7.widget.Toolbar>


     </android.support.design.widget.AppBarLayout>

     </android.support.design.widget.CoordinatorLayout>

我只想删除 SearchView 文本框旁边的图标。所以我旁边没有很大的空白空间。提前致谢！

您可以覆盖搜索视图默认图像或设置可见消失

int searchImgId = context.getResources().getIdentifier("android:id/search_mag_icon", null, null);
ImageView searchImage = (ImageView) searchView.findViewById(searchImgId);


searchImage.setVisibility(View.GONE);
