I have a problem with my ScrollView. It has an ImageView inside it. The imageView holds an image which is 480 * 3000 px. So It needs to be in a ScrollView so the user will have the ability to scroll down.
The problem is: when I test the application, the ScrollView does not wrap to the image hight. There is a black space under the image which is strange for me.
This is my XML code. I look forward for your opinion
<?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"
>
<ScrollView
android:id="@+id/scroll_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/image"
android:src="@drawable/image01"
android:scaleType="fitStart" />
</ScrollView>
</RelativeLayout>
Update: This is how my image looks like with @ruhalde code. I can't take a screenshoot since it is big and you'll not see the whole picture so I draw it.
Rewrite your layout. Make the ScrollView the outer most element. Take a look at this good tutorial for more information: http://mobiforge.com/designing/story/understanding-user-interface-android-part-1-layouts
Use a LinearLayout instead of RelativeLayout which is deprecated by now. Set fillViewPort=true in your ScrollView XML or programatically if you want with setFillViewPort(true).
Put imageview inside a LinearLayout and that inside ScrollView, your XML should look like this:
LinearLayout ---ScrollView ----LinearLayout ------ImageView
Check out my XML here working good with a 800 x 4000 pixels image, perfectly scrolling vertical:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ScrollView android:id="@+id/scrollView1"
android:layout_width="fill_parent" android:layout_height="wrap_content">
<LinearLayout android:id="@+id/linearLayout1"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<ImageView android:id="@+id/mapa" android:layout_height="wrap_content"
android:layout_width="wrap_content"></ImageView>
</LinearLayout>
</ScrollView>
</LinearLayout>
To those who might be interested:
My problem was with the image I'm using, not how I organize my layouts. Thanks.
我相信您应该在布局标签之前使用scrollView标签
