无法将ImageView与RelativeLayout的底部对齐

Question

I've read several tutorials on how to do this, but for whatever reason, my image won't budge from the center of the screen. The ninjas image is 1080x517px

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:weightSum="1"
              android:background="@color/white">

    <ImageView
        android:id="@+id/ninjas"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:src="@drawable/ninjas"
        android:layout_alignParentRight="true"
        android:layout_alignParentBottom="true"/>

</RelativeLayout>

From what I can tell, this is correct. Any suggestions? Thanks in advance

Answer 1

You make the image fill the parent currently. Change

    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

to

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

Answer 2

try this

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

<ImageView
    android:id="@+id/ninjas"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:src="@drawable/ic_launcher" />

 </RelativeLayout>

Try changing

<ImageView
    android:id="@+id/ninjas"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:src="@drawable/ninjas"
    android:layout_alignParentRight="true"
    android:layout_alignParentBottom="true"/>

to

<ImageView
    android:id="@+id/ninjas"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ninjas"
    android:layout_alignParentRight="true"
    android:layout_alignParentBottom="true"/>

At present your ImageView is occupying all the space in its parent. After changing layout_width and layout_height to wrap_content it will only occupy as much space as size of @drawable/ninjas

// Try this way,hope this will help you to solve your problem...

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    android:gravity="bottom|right"
    android:padding="5dp">

    <ImageView
        android:id="@+id/ninjas"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ninjas"
        android:adjustViewBounds="true"/>

</LinearLayout
