如何删除Android searchview左侧(不属于Actionbar的部分)上的空间? [英] How to remove space on the left side of Android searchview (which is not part of actionbar)?
本文介绍了如何删除Android searchview左侧(不属于Actionbar的部分)上的空间?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在android应用中使用了searchview( searchview不是操作栏的一部分).我想删除搜索图标/searchview左侧的空间.我进行了很多搜索，收到了一些答案，这些答案适用于操作栏上的搜索视图.
我尝试使用 android:layout_gravity，android:gravity ，但它们似乎没有用.我曾考虑使用 android:contentInsetStart，android:contentInsetLeft ，但是这些选项不适用于searchview(这不是操作栏的一部分).

(由于我的声誉低于10，所以不能直接在此处发布图片)
serchview位于LinearLayout(垂直方向)中.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>
解决方案
上面发布的图像链接不再起作用，因此我将假定这与我遇到的问题相同，如下图所示:
快速而肮脏的答案是在您的SearchView上使用负向左(/start)填充，如下所示(注意:这是删除了searchIcon的AppCompat SearchView).
<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，您可以将自定义布局设置为在初始化期间使用app:layout=R.layout.some_custom_layout进行夸大，您可以在其中手动修改填充/边距.如果您要采用此路线，建议您复制原始布局(在此处找到)，然后修改所需的值，请参见以下示例:
<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
<?xml version="1.0" encoding="utf-8"?>

我个人最终只是使用了前面提到的快速而又肮脏的方法，为了完整起见，我只是想将其包括在内.
如果我什么都错过了，打我一下.
I am using a searchview in android app (searchview is not a part of action bar). I want to remove the space on the left side of the search icon/ searchview. I searched a lot and received answers which worked for searchviews which are part of action bar.
I tried using android:layout_gravity, android:gravity, but they didnt seem to work. I thought of using android:contentInsetStart, android:contentInsetLeft, but these options are not available for searchview (which is not a part of action bar).

(cant post image directly here since my reputation is less than 10)
The serchview is in LinearLayout (vertical orientation). Here is the code which I am using :
<?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>
解决方案
The image link posted above no longer works, so I am going to assume that this is the same problem I came across as illustrated in the image below:
The quick and dirty answer for this is to use negative left(/start) padding on your SearchView as demonstrated below (caveats: this is the AppCompat SearchView with the searchIcon removed).
<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"
/>
Alternatively with the AppCompat SearchView you can set a custom layout to be inflated during initialisation with app:layout=R.layout.some_custom_layout in which you can modify the paddings/margins manually. If you are going to take this route I recommend copying the original layout (found here) and just modifying the values you need, see example below:
<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
<?xml version="1.0" encoding="utf-8"?>

I personally just ended up using the quick and dirty method mentioned first, I just wanted to include this for completeness.
