可能有很多事情，例如：您忘记将活动添加到清单中。但是我会继续猜测，你没有一个根布局，应该是这样的：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:scaleType="centerCrop"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:src="@drawable/androidparty" />


<TextView
android:text="Happy Birthday Mohamed"
android:layout_width="wrap_content"
android:textSize="36sp"
android:fontFamily="sans-serif-light"
android:textColor="@android:color/white"
android:layout_height="wrap_content"
android:id="@+id/textView2" />

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"

android:layout_marginBottom="24dp"
android:layout_marginEnd="13dp"
android:layout_marginRight="13dp"
android:text="From,Abo Elmagd"
android:textSize="36sp"
android:textColor="@android:color/white"
android:id="@+id/textView" />
</RelativeLayout>

编辑您的问题以包括logcat。请参阅：该logcat与异常无关。试着找出由引起的单词

，抱歉，我不明白我应该做什么请任何人帮助我：（请不要猜测糟糕问题的答案。等待那些如何评论的人来询问正确的信息。问题有错误的XML缩进。根元素在那里。请参阅更新当我回答时，它不是
