AppCompatActivity 作为没有标题的对话框

问题描述

我有一个继承自 AppCompactActivity 的 Activity.在活动集主题的清单中:

<style name="Theme.custom" parent="Theme.AppCompat.Light.Dialog"><item name="android:windowNoTitle">true</item><item name="colorPrimary">@color/primary</item><item name="colorPrimaryDark">@color/primary_dark</item><item name="colorAccent">@color/accent</item><item name="colorButtonNormal">@color/accent</item><item name="android:buttonStyle">@style/ButtonStyle</item></风格>

当我运行活动时，它显示为一个对话框，但显示了标题！我尝试 supportRequestWindowFeature(Window.FEATURE_NO_TITLE) 和 RequestWindowFeature(Window.FEATURE_NO_TITLE) 但标题仍然显示.请告诉我，有什么问题?

编辑

我解决了，只需将android:windowNoTitle改为windowNoTitle！因为我正在使用 AppCompactActvity！

如果你有 AppCompatActivity 那么下面的就不行了

requestWindowFeature(Window.FEATURE_NO_TITLE);

简单的方法是在style.xml文件中设置.

<style name="mytheme" parent="Theme.AppCompat.Light.Dialog"><item name="windowNoTitle">true</item></风格>

<块引用>

它是 name="windowNoTitle"，而不是 name="android:windowNoTitle"

如果您想以编程方式删除它，请在 onCreate()

getSupportActionBar().hide();

I have an Activity inherited from AppCompactActivity. in manifest for activity set theme:

<style name="Theme.custom" parent="Theme.AppCompat.Light.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primary_dark</item>
    <item name="colorAccent">@color/accent</item>
    <item name="colorButtonNormal">@color/accent</item>
    <item name="android:buttonStyle">@style/ButtonStyle</item>
</style>

When I run activity, it shows as a dialog, but title is shown! i try supportRequestWindowFeature(Window.FEATURE_NO_TITLE) and RequestWindowFeature(Window.FEATURE_NO_TITLE) but title still displayed. Please let me know, What is wrong?

Edit

I solve it, only change android:windowNoTitle to windowNoTitle! because i am use AppCompactActvity!

If you are having AppCompatActivity then the following won't work

requestWindowFeature(Window.FEATURE_NO_TITLE);

The simple way is to set it in the style.xml file.

<style name="mytheme" parent="Theme.AppCompat.Light.Dialog">
    <item name="windowNoTitle">true</item>
</style>

It is name="windowNoTitle", not name="android:windowNoTitle"

If you want to remove it programmatically then add the following in onCreate()

getSupportActionBar().hide();
