我在做HelloLinearLayout教程,但使用字符串資源,而不是像本教程那樣直接將字符串硬編碼到XML中。當我使用字符串資源運行應用程序時,它立即崩潰。當我將字符串硬編碼到XML代碼中時,一切正常。任何想法,爲什麼我的應用程序崩潰?由於當我嘗試訪問字符串資源時,爲什麼我的Android應用程序崩潰?
main.xml中
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_height="fill_parent"
android:layout_width="fill_parent">

並且你是一個簡短的' LinearLayout>'結束標記嗎? – dustmachine
