Error in android:theme="@*android:style/Theme.Translucent.NoTitleBar" could not be resolved.

it is from the manifest

回答1:

Change it to android:theme="@android:style/Theme.Translucent.NoTitleBar". You have added * after @ syb

Replace

android:theme="@*android:style/Theme.Translucent.NoTitleBar" 

with

android:theme="@android:style/Theme.Translucent.NoTitleBar" 

回答2:

Did you try to remove the asterisk (*) between @ and android:style/Theme.Translucent.NoTitleBar ?

Should simply be: android: theme="@android:style/Theme.Translucent.NoTitleBar"

回答3:

Add theme to you activity in manifest,

<activity android:name=".activityName"
 android:theme="@android:style/Theme.Translucent"/>

or

<activity android:name=".activityName"
android:theme="@android:style/Theme.Translucent.NoTitleBar"/>
