如何删除Android搜索视图左侧的空间(不属于操作栏)？

Question

我在android应用程序中使用searchview(searchview不是操作栏的一部分).我想删除搜索图标/ searchview左侧的空格.我搜索了很多,并收到了适用于搜索视图的答案,这些视图是操作栏的一部分.

我尝试使用android:layout_gravity,android:gravity,但它们似乎没有用.我想过使用android:contentInsetStart,android:contentInsetLeft,但这些选项不适用于searchview(这不是动作栏的一部分).

(由于我的声誉不到10,因此无法在此处直接发布图片)

serchview位于LinearLayout(垂直方向).这是我正在使用的代码:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:layout_height="match_parent"
    android:orientation="vertical"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context=".MainActivity"
    tools:showIn="@layout/activity_main">

    <SearchView
        android:id="@+id/searchView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="2dp"
        android:layout_gravity="left"
        android:gravity="left"
        />

    <ListView
        android:id="@+id/listView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/white" />

</LinearLayout>

上面发布的图片链接不再有效,所以我假设这是我遇到的同样问题,如下图所示:

造成这种情况的快速和肮脏的答案是使用负左(/启动)填充你的SearchView,如下面所示(注意事项:这是程序兼容性SearchView与searchIcon移除).

<android.support.v7.widget.SearchView
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:paddingLeft="-16dp"
  android:paddingStart="-16dp"
  app:iconifiedByDefault="false"
  app:searchIcon="@null"
  app:queryHint="Search"
  app:theme="@style/ThemeOverlay.AppCompat.Dark"
  />

或者使用AppCompat,SearchView您可以设置在初始化期间要充气的自定义布局app:layout=R.layout.some_custom_layout,您可以在其中手动修改填充/边距.如果您打算采用这种方法,我建议您复制原始布局(在此处找到)并只修改您需要的值,请参阅下面的示例:

<android.support.v7.widget.SearchView
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:paddingLeft="-16dp"
  android:paddingStart="-16dp"
  app:iconifiedByDefault="false"
  app:searchIcon="@null"
  app:queryHint="Search"
  app:theme="@style/ThemeOverlay.AppCompat.Dark"
  app:layout="@layout/search_view"
  />

search_view.xml

我个人最后使用了首先提到的快速而肮脏的方法,我只想将其包含在内以便完整.

Answer 2

android:paddingStart="-16dp"

对于后棒棒糖设备来说就足够了。

Answer 3

嘿，在 onCreate 中动态设置 SearchView 的填充并尝试 SearchView sv = findViewById(R.id.searchView1); sv.setPadding(0,2,0,0);
