在AppCompat中使用基于材质的对话框主题

Question

我在我的Manifest中有一个活动，我曾经用Dialog主题设计风格。我找不到如何在AppCompat库中替换它。

  <activity
            android:name=".LoginActivity"
            android:theme="@android:styles/Theme.Holo.Dialog" 
            android:configChanges="orientation|screenSize|keyboardHidden"
            android:label="Login" >

是否存在基于材料的等效物？

Answer 1

Java代码

    AlertDialog.Builder builder =
                    new AlertDialog.Builder(SecondActivity.this, R.style.AppCompatAlertDialogStyle);
            builder.setTitle("SCRUM");
            builder.setMessage("In the SCRUM methodology a sprint is the basic unit of development. Each sprint is preceded by a planning meeting, where the tasks for the sprint are identified and an estimated commitment for the sprint goal is made, and followed by a review or retrospective meeting where the progress is reviewed and lessons for the next sprint are identified. During each sprint, the team creates finished portions of a product.....");
            builder.setPositiveButton("OK", null);//second parameter used for onclicklistener
            builder.setNegativeButton("Cancel", null);
            builder.show();

使用此主题

  <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>

导入支持v7警告对话框

import android.support.v7.app.AlertDialog;

像这样的输出，

AppCompat中的对话框尚无基于材料的主题，请参阅here

Will appcompat automatically theme dialogs to look like the Lollipop version?

Not yet, but it's on the todo list.

<强>更新

在22.1的版本Support Library中，您现在可以使用AppCompatDialog

获取素材对话框样式

Answer 3

使用最新的Appcompat库

compile 'com.android.support:appcompat-v7:23.2.1'// or any version greater than 22.1

并在Manifest中使用以下主题

android:theme="@style/Theme.AppCompat.Light.Dialog"

我使用它在DialogFragment中构建对话框，并应用了自定义样式。效果很好。
