Android- ImageView not showing
提问by Lijap
I have this code:
我有这个代码：
<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout02"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView android:id="@+id/terranlogo1"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="@drawable/terranlogo"
android:layout_centerHorizontal="true"
/>
<ImageView android:id="@+id/protosslogo1"
android:layout_width="100dp"
android:layout_height="100dp"
android:gravity="top|right"
android:src="@drawable/protosslogo"
/>
<ImageView android:id="@+id/zergologo1"
android:layout_width="100dp"
android:layout_height="100dp"
android:gravity="top|left"
android:src="@drawable/zerglogo"
/>
The image view on the right is not showing. The other 2 are just fine, I even tried setting them to 50 dp and the "protosslogo1" still does not show. What am I doing wrong?
右侧的图像视图未显示。其他 2 个都很好，我什至尝试将它们设置为 50 dp，但“protosslogo1”仍然没有显示。我究竟做错了什么？
Thanks, All help is appreciated- Lijap

Position your ImageViewslike this:
ImageViews像这样定位：
<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout02"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView android:id="@+id/terranlogo1"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="@drawable/terranlogo"
android:layout_centerHorizontal="true"
/>
<ImageView android:id="@+id/protosslogo1"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_alignParentRight="true"
android:src="@drawable/protosslogo"
/>
<ImageView android:id="@+id/zergologo1"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_alignParentLeft="true"
android:src="@drawable/zerglogo"
/>
Right now protosslogo1is behind zergologo1. You're using android:gravitythat is used to place the content(and the size of your ImageViewis fixed so it doesn't matter) of the View. Second, you don't have any rules set on your ImageViewsso they are placed by default(in a RelativeLayout) in the top-left corner.
现在protosslogo1是落后zergologo1。您使用android:gravity的是用于将内容放置（和你的大小ImageView是固定的，因此并不重要）的View。其次，您没有设置任何规则，ImageViews因此默认情况下（在 a 中RelativeLayout）将它们放置在左上角。

you can use:
您可以使用：
android:background="@drawable/terranlogo"
instead of:
代替：
android:src="@drawable/terranlogo"
