如何使用appCompat 22.1及更高版本中的新AlertDialog并为其设置样式

问题描述

我正在尝试从默认的android AlertDialog迁移到appCompat-22.1中包含的新版本到目前为止，我了解您只需导入android.support.v7.app.AlertDialog软件包即可使用它.

I am trying to migrate from default android AlertDialog to the new one included in appCompat-22.1 So far I understand you only have to import android.support.v7.app.AlertDialog package in order to use it.

但是我该如何设计呢?例如更改正/负按钮颜色，标题颜色，消息颜色和背景颜色?

But how can I style it? For example change the positive/negative button colors, title color, message color and background color?

推荐答案

创建AlertDialog时，您可以设置要使用的主题.

When creating the AlertDialog you can set a theme to use.

示例-创建对话框

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

styles.xml-自定义样式

<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <!-- Used for the buttons -->
    <item name="colorAccent">#FFC107</item>
    <!-- Used for the title and text -->
    <item name="android:textColorPrimary">#FFFFFF</item>
    <!-- Used for the background -->
    <item name="android:background">#4CAF50</item>
</style>

结果

修改

要更改标题的外观，可以执行以下操作.首先添加新样式:

In order to change the Appearance of the Title, you can do the following. First add a new style:

<style name="MyTitleTextStyle">
    <item name="android:textColor">#FFEB3B</item>
    <item name="android:textAppearance">@style/TextAppearance.AppCompat.Title</item>
</style>

之后，只需在您的MyAlertDialogStyle中引用此样式:

afterwards simply reference this style in your MyAlertDialogStyle:

<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    ...
    <item name="android:windowTitleStyle">@style/MyTitleTextStyle</item>
</style>

这样，您可以通过android:textColorPrimary为消息定义不同的textColor，并通过样式为标题定义不同的

This way you can define a different textColor for the message via android:textColorPrimary and a different for the title via the style.
