I want the entire activity to be scrollable but only listview is scrollable. How do I do that?

I pull data into my listview from servers. The listview is inside an activity. The activity has buttons above it.
When the data is received and when I scroll data, only listview is scrolled. The buttons remain fixed at the top.
I want the listview to take the required vertical height it needs so that I would need to scroll the activity instead of the listview.
My XML code :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:text="text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/view_c_name"
android:textSize="18sp"
android:textStyle="bold"/>
<TextView
android:text="text4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/view_c_name"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:id="#+id/view_c_motto" />
<TextView
android:text="text5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/view_c_motto"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:id="#+id/view_c_details" />
<TextView
android:text="text2"

android:id="#+id/view_c_address"

android:layout_alignParentStart="true" />
<TextView
android:text="text3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/view_c_act_text"
android:layout_below="#+id/view_c_address"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginTop="71dp" />
<Button
android:text="Button 1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginStart="16dp"
android:id="#+id/view_button"
android:layout_below="#+id/view_c_address"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<Button
android:text="button 2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/view_button"
android:layout_toRightOf="#+id/view_button"
android:layout_toEndOf="#+id/view_button"
android:layout_marginLeft="16dp"
android:layout_marginStart="16dp"
android:id="#+id/view_button2" />
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/view_c_act_text"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:id="#+id/my_listview"
android:scrollbars="none"
/>
</RelativeLayout>

The perfect code should be;
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!--Inside the below layout your buttons will come. Modify it accordingly-->
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<!--Your buttons will come here-->
</LinearLayout>
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
As shown above, Nested Scroll View should be used instead of Scroll View because
there is a need of scrolling view (in this case List View) inside another scrolling view. The system is unable to decide which view to scroll and this is where Nested Scroll View comes in.

Wrap your existing layout in a ScrollView to scroll the entire thing, not just the ListView
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- your existing layout here, change your top container's height from match_parent to wrap_content -->
</ScrollView>

Try this one
<ScrollView
android:id="#+id/scrollViewMain"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/linearLayoutMain"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:text="Button"
android:id="#+id/buttonMain"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</LinearLayout>
</ScrollView>

<RelativeLayout
android:layout_width="match_parent">
android:layout_height="match_parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
"your existing layout here, change your top container's height from match_parent or wrap_content "
the best case secanrio is to use scroll View inside of an relative layout and all the existing code inside of the scrollView

I had similar problem then I created a class
public class ListViewExpanded extends ListView {
public ListViewExpanded(Context context, AttributeSet attrs) {
super(context, attrs);
setDividerHeight(0);
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST));
}
}
then I used in xml as try it out it will help for sure
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:id="#+id/text_goal_scored"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<example.ListViewExpanded
android:id="#+id/list_home"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
</example.ListViewExpanded>
</android.support.v4.widget.NestedScrollView>

Go through this Example. Make ScroolView as Parent. It Work Form me.
<ScrollView android:layout_width="match_parent"

Maybe it's better to move your ListView in other Activity, which will extend ListActivity. Then it will definitely be scrollable.

Hi By default listview can't add inside a scrollview.For doing this you need to either calculate the size of list view based on item or you need to override the onMeasure of listview.
Added below a custom Listview with overrid onMeasure method use this listview instead of the default one.Also make sure in xml file the heigh should be wrap_content.
Also make scrollview's fillviewport property to true inorder to use full height.
public class MyListView extends ListView {
public MyListView(Context context) {
super(context);
}
public MyListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int heightSpec;
if (getLayoutParams().height == LayoutParams.WRAP_CONTENT) {
// The two leftmost bits in the height measure spec have
// a special meaning, hence we can't use them to describe height.
heightSpec = MeasureSpec.makeMeasureSpec(
Integer.MAX_VALUE >>2, MeasureSpec.AT_MOST);
}
else {
// Any other height should be respected as is.
heightSpec = heightMeasureSpec;
}
super.onMeasure(widthMeasureSpec, heightSpec);
}
}

public void showListView() {
dbList = (ListView) findViewById(R.id.listDatabase);
ListAdapter listAdapter = dbList.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
int desiredWidth = MeasureSpec.makeMeasureSpec(
dbList.getWidth(), MeasureSpec.AT_MOST);
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, dbList);
listItem.measure(desiredWidth,
MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = dbList.getLayoutParams();
params.height = totalHeight
+ (dbList.getDividerHeight() * (listAdapter
.getCount() - 1)) + 30;
dbList.setLayoutParams(params);
dbList.requestLayout();
}

GridView does not expand

I am kinda new in android and got such a problem, I am trying to use ExpandableHeightGridView for gridview inside scrollview, but layout doesn't render, some advice please.
It always gives me this error:
Exception raised during rendering: ScrollView can host only one direct child
ExpandableHeightGridView.class:
public class ExpandableHeightGridView extends GridView {
boolean expanded = false;
public ExpandableHeightGridView(Context context)
{
super(context);
}
public ExpandableHeightGridView(Context context, AttributeSet attrs)
{
super(context, attrs);
}
public ExpandableHeightGridView(Context context, AttributeSet attrs,
int defStyle)
{
super(context, attrs, defStyle);
}
public boolean isExpanded()
{
return expanded;
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
// HACK! TAKE THAT ANDROID!
if (isExpanded())
{
// Calculate entire height by providing a very large height hint.
// View.MEASURED_SIZE_MASK represents the largest height possible.
int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
else
{
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
public void setExpanded(boolean expanded)
{
this.expanded = expanded;
} }

This problem is discussed here.
Try adding one more LinearLayout inside your ScrollView as a direct child and put all other layouts/controls inside of the new LinearLayout.

Is it possible to check if a specific "TAB" in TabWidget is visible in current View or not?

I have a TabWidget with 5 tabs in it. Tabs : "One","Two","Three","Four","Five". The TabHost is in a HorizontalScrollView. Now I've one arrow (< and >) each on each side of the TabWidget to indicate that there are more tabs in that direction(which are currently not visible in view).
Now what I want to do is, if the first tab is not visible(in current view) then the arrow to left (<) should be visible and if the last tab is not visible(in current view) then the arrow to right should be visible and if both tabs are not visible(in current view) then both arrows should be visible. I tried doing it with:
if (horizontablscrollview.getLeft == 0)
{
arrowRight.setVisiblity(View.VISIBLE)
arrowLeft.setVisiblity(View.INVISIBLE)
}
else if( horizontablscrollview.getRight == 0)
{
arrowLeft.setVisiblity(View.VISIBLE)
arrowRight.setVisiblity(View.INVISIBLE)
}
else if ( horizontablscrollview.getRight == 0 && horizontablscrollview.getLeft == 0)
{
arrowRight.setVisiblity(View.VISIBLE)
arrowLeft.setVisiblity(View.VISIBLE)
}
But this doesn't work, my both tabs are invisible in the start:
my xml looks like this..

Any help would be greatly appreciated.

One solution would be to make you own HorizontalScrollView class and show the ImageViews based on the scroll(although I didn't tested that much the code below should work). Your layout will look like this:
//...
<RelativeLayout
android:id="#+id/rl_tabs"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView android:id="#+id/arrow_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/i_button"
android:layout_alignParentLeft="true"
android:visibility="gone"/>
<ImageView android:id="#+id/arrow_Right"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/i_button"
android:layout_alignParentRight="true"
/>
<com.your.package.here.SpecialScroll
android:id="#+id/my_scrollView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:scrollbars="none" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:tabStripEnabled="true"/>
</com.your.package.here.SpecialScroll>
</RelativeLayout>
//...
The SpecialScroll class will look like this:
public class SpecialScroll extends HorizontalScrollView {
public interface PositionListener {
public void onLeftArrowRequired(boolean required);
public void onRightArrowRequired(boolean required);
public View implementScrolledView();
}
private PositionListener listener;
public void setPositionListener(PositionListener listener) {
this.listener = listener;
}
public SpecialScroll(Context context) {
super(context);
}
public SpecialScroll(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public SpecialScroll(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
super.onScrollChanged(l, t, oldl, oldt);
if (l == 0) {
listener.onLeftArrowRequired(false);
} else {
listener.onLeftArrowRequired(true);
}
View v = listener.implementScrolledView();
Rect r = new Rect();
v.getDrawingRect(r);
if ((r.width() - l) == getWidth()) {
listener.onRightArrowRequired(false);
} else {
listener.onRightArrowRequired(true);
}
}
}
Then in your activity's onCreate method you'll do:
SpecialScroll hsv = (SpecialScroll) findViewById(R.id.my_scrollView);
hsv.setPositionListener(this); // I made the activity implement the SpecialScroll.PositionListener interface
and the activity's implementation of the PositionListener interface is:
#Override
public void onLeftArrowRequired(boolean required) {
if (required) {
((ImageView) findViewById(R.id.arrow_left))
.setVisibility(View.VISIBLE);
} else {
((ImageView) findViewById(R.id.arrow_left))
.setVisibility(View.GONE);
}
}
#Override
public void onRightArrowRequired(boolean required) {
if (required) {
((ImageView) findViewById(R.id.arrow_right))
.setVisibility(View.VISIBLE);
} else {
((ImageView) findViewById(R.id.arrow_right))
.setVisibility(View.GONE);
}
}
#Override
public View implementScrolledView() {
return findViewById(android.R.id.tabs);
}

This isn't an elegant solution, but you could display the left arrow if the x coordinate of the leftmost tab was less than zero and display the right tab if the rightmost tab's x plus its width was greater than the screen width.

How to resize an ImageView in Android?

I am trying to do something similar to the image below in Android. The problem is, whenever the screen size changes (when the user rotates the device), the checkboxes and the button disappear from the screen. This is my layout
<?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" >
<ImageView
android:id="#+id/preview"
android:layout_width="fill_parent"
android:contentDescription="#string/content_description"
android:layout_height= "1.5in" />
<CheckBox
android:id="#+id/location"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/preview"
android:text="#string/location_text" />
<CheckBox
android:id="#+id/timestamp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/location"
android:text="#string/timestamp_text" />
<Button
android:id="#+id/buttonUpload"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="#+id/timestamp"
android:layout_marginRight="19dp"
android:gravity="center_vertical"
android:onClick="uploadClicked"
android:text="#string/upload_button_text" />
</RelativeLayout>
I need to display the image and all controls and support all screen sizes. How do I make the size of the ImageView dynamic?

I never got the scaleType thing to work for me.
I subclassed ImageView:
package your.pkg;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;
public class AspectRatioImageView extends ImageView {
public AspectRatioImageView(Context context) {
super(context);
}
public AspectRatioImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public AspectRatioImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int width = MeasureSpec.getSize(widthMeasureSpec);
if (getDrawable() != null && getDrawable().getIntrinsicWidth() != 0) {
int height = width * getDrawable().getIntrinsicHeight() / getDrawable().getIntrinsicWidth();
setMeasuredDimension(width, height);
} else {
setMeasuredDimension(0, 0);
}
}
}
And used that instead of the regular ImageView:
<your.pkg.AspectRatioImageView
android:id="#+id/photo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentTop="true"
android:adjustViewBounds="true"
/>
This scales to the full width of the parent View and maintains the aspect ratio while doing so.

If you used a LinearLayout instead of a RelativeLayout, you could make the ImageView expand to take all the empty space in the screen. The scaleType attribute will let you specify how to stretch the image.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="#+id/preview"
android:layout_width="fill_parent"
android:contentDescription="#string/content_description"
android:layout_height="0dp"
android:layout_weight="1"
android:scaleType="fitCenter" />
<CheckBox
android:id="#+id/location"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/location_text" />
<CheckBox
android:id="#+id/timestamp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/timestamp_text" />
<Button
android:id="#+id/buttonUpload"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="19dp"
android:layout_gravity="right"
android:onClick="uploadClicked"
android:text="#string/upload_button_text" />
</LinearLayout>

Based on all the feedback. This is what I used:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scroller"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="#+id/preview"
android:layout_width="fill_parent"
android:contentDescription="#string/content_description"
android:layout_height= "1.5in" />
<CheckBox
android:id="#+id/location"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/preview"
android:text="#string/location_text" />
<CheckBox
android:id="#+id/timestamp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/location"
android:text="#string/timestamp_text" />
<Button
android:id="#+id/buttonUpload"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="#+id/timestamp"
android:layout_marginRight="19dp"
android:gravity="center_vertical"
android:onClick="uploadClicked"
android:text="#string/upload_button_text" />
</RelativeLayout>
</ScrollView>
