Question

我想在我的程序中插入图像为bg。我添加了 andriod：background 但我没有在设计部分获取图像

`

 <?xml version="1.0" encoding="utf-8"?>
 <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:andriod="http://schemas.android.com/apk/res-auto"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:paddingTop="16dp"
    tools:context="com.example.madhu.c_indicator.MainActivity"
    andriod:background="@drawable/bg2">



</RelativeLayout>

当我运行程序时出现以下错误

Answer 1

行andriod中有拼写错误：background =＆＃34; @ drawable / bg2＆＃34;改变＆＃39; andriod＆＃39;到＆＃39; android＆＃39;

Answer 2

你的代码中有拼写错误，所以

更改

$this->blog_db->query('SELECT a.tytul, b.post_id, a.data_dodania, COUNT(b.post_id) as liczba
                                    FROM posts a
                                    JOIN komentarze b ON a.id=b.post_id
                                    GROUP BY b.post_id
                                    ORDER BY liczba desc
                                    LIMIT 0, 5
                                    ');

这

andriod:background="@drawable/bg2"

Answer 3

您的代码上有拼写错误。而不是'andriod：background'使用''android：background'

背景图像不能插入
