在Appcompat 22.2中Edittext颜色为白色 [英] Edittext color is white in appcompat 22.2

问题描述

这是由于行

<item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>

styles.xml中的

.我正在使用它来显示浅色(白色)文本和ToolBar中的返回主页"按钮.如果我将其更改为<item name="theme">@style/ThemeOverlay.AppCompat.Light</item>，则EditText可以按预期工作，但是我的ToolBar文本和后方首页按钮颜色将变为暗(黑色).

当我使用深色的ToolBar时，我想以浅色(白色)显示文本和返回主页按钮.

我尝试使用<item name="android:theme">...</item>而不是<item name="theme">...</item>，但是没有任何帮助，工具栏文本和后退按钮仍然保持深色！有人知道吗?救救我！

实际问题:

在appcompat-v7:22.2.0中，我使用了EditText.我正在为Activity

使用以下主题

<style name="AppThemeNoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/myPrimaryColor</item>
    <item name="colorPrimaryDark">@color/myPrimaryDarkColor</item>
    <item name="colorAccent">@color/myAccentColor</item>
    <item name="android:windowBackground">@color/myWindowBackground</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
    <item name="popupTheme">@style/ThemeOverlay.AppCompat.Light</item>
    <item name="colorControlHighlight">#0000AA</item>
</style>

但是EditText的颜色是白色.底线，提示和文本均为白色.我听说AppCompat中存在错误，但是如何解决此问题?

XML文件:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_marginTop="@dimen/marintopforelements"
          android:gravity="center"
          android:orientation="vertical"
          android:padding="10dp"
          android:paddingTop="@dimen/templatePaddingTop">

          <android.support.v7.widget.AppCompatEditText
                android:id="@+id/emailresponse"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="left|center"
                android:layout_marginLeft="@dimen/examtextdiff"
                android:imeOptions="actionNext"
                android:inputType="textEmailAddress"
                android:minLines="2"
                android:paddingRight="5dp"
                android:textSize="@dimen/inboxTabTextSize"/>

</LinearLayout>

colors.xml

<color name="myPrimaryColor">#3F51B5</color>
<color name="myPrimaryDarkColor">#FF304081</color>
<color name="myAccentColor">#3F51B5</color>

所以以前我在使用AppCompat-V7:21时，它就像下面的图像一样

但是升级到AppCompat-V7:22.2.0后，如下图所示

因此，如果它像下面的图像一样聚焦它的到来

仅该光标线具有给定的强调色.但是提示和文本始终为白色！甚至在EditText和AppCompatEditText中都在发生这种情况，希望对您有所帮助

解决方案

好的，我已解决问题！

我正在做的是，我想以白色显示ToolBar内容，因为我的工具栏很暗，所以我使用了这行

styles.xml

中的

<item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>

在appcompat-v7:21.+上运行正常.

但是在appcompat-v7:22.2.0中，由于app:theme被贬值(@Guillaume Imbert在他的回答中提到).

这就是混乱.我在项目中的任何地方都没有使用过"app:theme"，但它仍然向我显示警告.因此，我再次谷歌搜索并找到了此链接.

哪些人引导我关注Chris的博客Banes 对此进行了清晰的解释.

现在我从styles.xml中删除了<item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>.所以我的ToolBar内容是暗的(黑色).

最后在ToolBar中添加android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"达到了目的，所以我的工具栏代码看起来像

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="@dimen/action_bar_size_x2"
    android:background="@color/myPrimaryColor"
    android:minHeight="?attr/actionBarSize"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>

因此，这可能会对某人有所帮助.

感谢@reVerse和@Guillaume Imbert给我带来好的领导.没有您的回答，我将无法解决.非常感谢:)

EDIT 2 : This is happening because of the line

<item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>

in styles.xml. I'm using this to display light color (white) texts and back home button in ToolBar. If i change this to <item name="theme">@style/ThemeOverlay.AppCompat.Light</item> then EditText is working as expected but my ToolBar text and back home button colors are changes to dark (black).

As I'm using dark colored ToolBar I would like to show the text and back home button in light (white) color.

I tried using <item name="android:theme">...</item> instead of <item name="theme">...</item> But nothing helped me, The toolbar text and back button still remains dark color! Any one figured out? Help me!

ACTUAL QUESTION :

In an appcompat-v7:22.2.0 I used an EditText. An I'm using following theme for an Activity

<style name="AppThemeNoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/myPrimaryColor</item>
    <item name="colorPrimaryDark">@color/myPrimaryDarkColor</item>
    <item name="colorAccent">@color/myAccentColor</item>
    <item name="android:windowBackground">@color/myWindowBackground</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
    <item name="popupTheme">@style/ThemeOverlay.AppCompat.Light</item>
    <item name="colorControlHighlight">#0000AA</item>
</style>

But the color of an EditText is coming in white color. Bottom line, hint and text all are in white. I heard there is a bug in AppCompat But how to resolve this?

EDIT 1 : Adding more information

XML file :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_marginTop="@dimen/marintopforelements"
          android:gravity="center"
          android:orientation="vertical"
          android:padding="10dp"
          android:paddingTop="@dimen/templatePaddingTop">

          <android.support.v7.widget.AppCompatEditText
                android:id="@+id/emailresponse"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="left|center"
                android:layout_marginLeft="@dimen/examtextdiff"
                android:imeOptions="actionNext"
                android:inputType="textEmailAddress"
                android:minLines="2"
                android:paddingRight="5dp"
                android:textSize="@dimen/inboxTabTextSize"/>

</LinearLayout>

colors.xml

<color name="myPrimaryColor">#3F51B5</color>
<color name="myPrimaryDarkColor">#FF304081</color>
<color name="myAccentColor">#3F51B5</color>

So previously when I was using AppCompat-V7:21 It was coming like below image

But after upgrading to AppCompat-V7:22.2.0 Its like below image

So if it focused its coming like below image

Only that cursor line is in given accent color. But the hint and text are always in white! And this is happening even in both EditText and AppCompatEditText Hope this helps

解决方案

Okie, I fixed it!

What I was doing was, I want to display ToolBar content in white color as my ToolBar is dark so I used this line

<item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item> in styles.xml

This was working fine with appcompat-v7:21.+.

But in appcompat-v7:22.2.0 as the app:theme was depreciated (mentioned by @Guillaume Imbert in his answer).

So here was the confusion. I didn't use 'app:theme` any where in my project but it still keep showing me warning. So again I googled and found the this link.

Which leads me to following blog by Chris Banes clearly explained about it.

Now I removed <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item> from styles.xml. So my ToolBar content is dark (Black).

Finally adding android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" in my ToolBar did the trick, So my toolbar code looks like

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="@dimen/action_bar_size_x2"
    android:background="@color/myPrimaryColor"
    android:minHeight="?attr/actionBarSize"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>

So this may help someone.

Thanks for giving me the good lead, both @reVerse and @Guillaume Imbert. Without your answers I would not able to fix this. Thanks a Lot :)
