ScrollView not scrolling - Android

I do not understand why this is happening. I can not scroll my scrollview. It has a textView, an image, and several linear layouts inside it. When I replace the image and line layouts with textview, it works. This is really unusual and unpleasant. Can someone help me? Here is my code:

<LinearLayout 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" > <ScrollView android:id="@+id/scrollView1" android:layout_width="match_parent" android:layout_height="match_parent" android:fillViewport="true" > <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:animateLayoutChanges="true" android:orientation="vertical" android:scrollbars="vertical" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:text="Drop Text Down" android:textAppearance="?android:attr/textAppearanceLarge" /> <ImageView android:id="@+id/imageView1" android:layout_width="match_parent" android:layout_height="555dp" android:src="@drawable/ic_launcher" /> <LinearLayout android:layout_width="match_parent" android:layout_height="100dp" android:orientation="vertical" > <TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextView" /> </LinearLayout> <LinearLayout android:id="@+id/ln" android:layout_width="match_parent" android:layout_height="100dp" android:background="#000000" android:orientation="vertical" > <LinearLayout android:layout_width="match_parent" android:layout_height="100dp" android:orientation="vertical" > <TextView android:id="@+id/TextView06" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextView" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="100dp" android:orientation="vertical" > <TextView android:id="@+id/TextView05" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextView" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="100dp" android:orientation="vertical" > <TextView android:id="@+id/TextView04" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextView" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="100dp" android:orientation="vertical" > <TextView android:id="@+id/TextView03" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextView" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="100dp" android:orientation="vertical" > <TextView android:id="@+id/TextView02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextView" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="100dp" android:orientation="vertical" > <TextView android:id="@+id/TextView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextViewTextView" /> </LinearLayout> </LinearLayout> </LinearLayout> </ScrollView> </LinearLayout>

Thanks.

The child view of ScrollView must be set to wrap_content. If you set it to match_parent, it will fill in the ScrollView area and will never scroll, because it will not be bigger than ScrollView .

Try changing the LinearLayout child to either wrap_content or a specific size (in dp) instead of match_parent.

Place a blank view with a fixed height

 <View android:layout_width="match_parent" android:layout_height="50dp" />

like your last element in a line layout that is a child of a scroll.

It worked for me ..

Your ScrollView child should have its height as wrap_content :

 <ScrollView android:id="@+id/scrollView1" android:layout_width="match_parent" android:layout_height="match_parent" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:animateLayoutChanges="true" android:orientation="vertical" android:scrollbars="vertical" > ... ... </LinearLayout> </ScrollView>

You must set the height of LinearLayout (child of Scrollview) to wrap_content.

When a child is taller than ScrollView, the android: fillViewport = "true" attribute has no effect.

I had the same problem and managed to solve by placing the following code in the body of my fragment

 getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

 <ScrollView android:id="@+id/scrollView1" android:layout_width="match_parent" android:layout_height="match_parent" android:fillViewport="true" >

Remove android: fillViewport = "true" from the previous item

use the Layout table instead of a line layout something like this:

 <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:fadeScrollbars="false" android:padding="6dip"> <TableLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:stretchColumns="1" > //your stuff </TableLayout> </ScrollView>
