無法啓動活動資源$ NotFoundException：.xml從xml佈局資源ID＃0x7f040031

我的佈局xml文件有問題..我的錯誤是;

Fatal Exception: java.lang.RuntimeException: Unable to start activity ComponentInfo android.content.res.Resources$NotFoundException: File res/layout/activity_splash.xml from xml type layout resource ID #0x7f040031

    at dalvik.system.NativeStart.main(NativeStart.java)

和我的xml佈局是;

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
xmlns:wheel="http://schemas.android.com/apk/res-auto" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
android:paddingBottom="@dimen/activity_vertical_margin" 
tools:context=".SplashActivity"> 

<com.pnikosis.materialishprogress.ProgressWheel 
    android:id="@+id/progress_wheel" 
    android:layout_width="80dp" 
    android:layout_height="80dp" 
    android:layout_centerHorizontal="true" 
    android:layout_centerVertical="true" 
    wheel:matProg_barColor="#E5E4E2" 
    wheel:matProg_progressIndeterminate="true" /> 
</RelativeLayout>

這裏是我的錯誤行;

setContentView(R.layout.activity_splash);

我的問題是什麼？非常感謝現在...

在你的build.gradle依賴性增加：

compile 'com.pnikosis:materialish-progress:1.7'

或者代碼：

ProgressWheel wheel = new ProgressWheel(context); 
wheel.setBarColor(Color.BLUE);

PLZ檢查你的build.gradle文件中添加

我在之前添加了編譯行。但是不起作用 –
