Android v21 Theme.Appcompat 颜色重音被忽略，对话框上没有填充

Android v21 Theme.Appcompat color accent is ignored, no padding on dialogs

提问by k1slay

I'm using ActionBarActivityfrom the Android 5 SDK and here is my theme.xmlfor v21

我正在使用Android 5 SDK 中的ActionBarActivity，这是v21 的theme.xml

<style name="AppTheme_Light" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:colorPrimary">@color/abc1</item>
    <item name="android:colorPrimaryDark">@color/abc2</item>
    <item name="android:colorAccent">@color/abc3</item>
</style>

But the colors are ignored, and are replaced by a default teal color and all the dialogs appear without padding.

但是颜色会被忽略，并被默认的青色替换，并且所有对话框都没有填充。

Also, padding is also ignored in other places like custom toast, problem only occurs in lollipop devices.

此外，在自定义吐司等其他地方也忽略了填充，问题只发生在棒棒糖设备中。

Edit:

编辑：

The padding problem was due to fitsSystemWindowand I got it fixed using
this question..

填充问题是由于fitsSystemWindow，我使用
这个问题修复了它。.

But the accent color problem is still there, and it does not just affect dialogs but the whole app.

但是强调色问题仍然存在，它不仅影响对话框，还影响整个应用程序。

About the accent color. You are using a AppCompat theme so you should remove Android from the namespace inside your theme.

关于强调色。您正在使用 AppCompat 主题，因此您应该从主题内的命名空间中删除 Android。

<style name="AppTheme_Light" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/abc1</item>
    <item name="colorPrimaryDark">@color/abc2</item>
    <item name="colorAccent">@color/abc3</item>
</style>

About the dialog. AppCompat doesn't support it (as I know).
You can try to use this style in your values-v21folder:

关于对话框。AppCompat 不支持它（据我所知）。
您可以尝试在values-v21文件夹中使用此样式：

<style name="Theme" parent="FrameworkRoot.Theme">
    <item name="android:alertDialogTheme">@style/Theme.AlertDialog</item>
</style>

<style name="Theme.AlertDialog" parent="android:Theme.Material.Light.Dialog.Alert">
    <item name="android:colorPrimary">@color/demo_primary_color</item>
    <item name="android:colorPrimaryDark">@color/demo_colorPrimaryDark</item>
    <item name="android:colorAccent">@color/theme_accent_1</item>
</style>

UPDATE 23/04/2015: SUPPORT LIBRARY V.22.1

23/04/2015 更新：支持库 V.22.1

The new support library v22.1works with the Dialog. You can use an android.support.v7.app.AlertDialogor the new AppCompatDialog.

新的support library v22.1作品与对话框。您可以使用android.support.v7.app.AlertDialog或新的AppCompatDialog。

For example:

例如：

import android.support.v7.app.AlertDialog

AlertDialog.Builder builder =
       new AlertDialog.Builder(this, R.style.AppCompatAlertDialogStyle);
            builder.setTitle("Dialog");
            builder.setMessage("Lorem ipsum dolor ....");
            builder.setPositiveButton("OK", null);
            builder.setNegativeButton("Cancel", null);
            builder.show();

And use a style like this:

并使用这样的风格：

<style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="colorAccent">#FFCC00</item>
    <item name="android:textColorPrimary">#FFFFFF</item>
    <item name="android:background">#5fa3d0</item>
</style>

Otherwise you can define in your current theme:

否则，您可以在当前主题中定义：

<style name="AppTheme" parent="Theme.AppCompat.Light">
    <!-- your style -->
    <item name="alertDialogTheme">@style/AppCompatAlertDialogStyle</item>
</style>

and then in your code:

然后在你的代码中：

 import android.support.v7.app.AlertDialog

    AlertDialog.Builder builder =
           new AlertDialog.Builder(this);

Current version of AppCompat doesn't apply colorization to AlertDialogs.

当前版本的 AppCompat 未对 AlertDialogs 应用着色。
