How to implement same transitions?

Please help, I'm trying to implement the same transitions.
1)https://storage.googleapis.com/spec-host-backup/mio-design%2Fassets%2F1tAlSW8Kp7JlXJNo16cv6RZqUl1iNsjen%2Fcards-transition.mp4
2)https://storage.googleapis.com/spec-host-backup/mio-design%2Fassets%2F1qIHOMquJE7flVh1ttDTSogXdvEX2lY_1%2F01-list-parentchild.mp4
But I don`t know how can I do it.

You need put this parameter into imageview of the first activity (xml):
android:transitionName="your_transaction_name"
And when you want open the other activity:
ImageView imageView = findViewById(R.id.your_image_id);
Pair pair = new Pair<>(imageView, ViewCompat.getTransitionName(imageView));
ActivityOptionsCompat transitionActivityOptions = ActivityOptionsCompat.makeSceneTransitionAnimation(this, pair);
Intent intent = new Intent(this, YourOtherActivity.class);
ActivityCompat.startActivityForResult(this, intent, 0, transitionActivityOptions.toBundle());
Add on your OtherActivity the same parameter to your imageView:
android:transitionName="your_transaction_name"
Note: It works only with android API > 21

The transition in the gif on the left side transitions the list element into the content area of the second activity (Toolbar stays in place). In the gif on the right side, the transition transforms the list element into the complete screen of the second activity. The following code provides the effect in the left gif. However, it should be possible to adapt the solution with minor modifications to achieve the transition in the right gif.
Note this only works on Lollipop. However, it is possible to mock a different effect on older devices. Furthermore, the sole purpose of the provided code is to show how it could be done. Don't use this directly in your app.
MainActivity:
public class MainActivity extends AppCompatActivity {
MyAdapter myAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setSupportActionBar((Toolbar) findViewById(R.id.toolbar));
ListView listView = (ListView) findViewById(R.id.list_view);
myAdapter = new MyAdapter(this, 0, DataSet.get());
listView.setAdapter(myAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, final View view, final int position, long id) {
startTransition(view, myAdapter.getItem(position));
}
});
}
private void startTransition(View view, Element element) {
Intent i = new Intent(MainActivity.this, DetailActivity.class);
i.putExtra("ITEM_ID", element.getId());
Pair<View, String>[] transitionPairs = new Pair[4];
transitionPairs[0] = Pair.create(findViewById(R.id.toolbar), "toolbar"); // Transition the Toolbar
transitionPairs[1] = Pair.create(view, "content_area"); // Transition the content_area (This will be the content area on the detail screen)
// We also want to transition the status and navigation bar barckground. Otherwise they will flicker
transitionPairs[2] = Pair.create(findViewById(android.R.id.statusBarBackground), Window.STATUS_BAR_BACKGROUND_TRANSITION_NAME);
transitionPairs[3] = Pair.create(findViewById(android.R.id.navigationBarBackground), Window.NAVIGATION_BAR_BACKGROUND_TRANSITION_NAME);
Bundle b = ActivityOptionsCompat.makeSceneTransitionAnimation(MainActivity.this, transitionPairs).toBundle();
ActivityCompat.startActivity(MainActivity.this, i, b);
}
}
activity_main.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar

android:transitionName="toolbar" />
<ListView
android:id="#+id/list_view"
android:layout_width="match_parent"

</LinearLayout>
DetailActivity:
public class DetailActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);
setSupportActionBar((Toolbar) findViewById(R.id.toolbar));
long elementId = getIntent().getLongExtra("ITEM_ID", -1);
Element element = DataSet.find(elementId);
((TextView) findViewById(R.id.title)).setText(element.getTitle());
((TextView) findViewById(R.id.description)).setText(element.getDescription());
// if we transition the status and navigation bar we have to wait till everything is available
TransitionHelper.fixSharedElementTransitionForStatusAndNavigationBar(this);
// set a custom shared element enter transition
TransitionHelper.setSharedElementEnterTransition(this, R.transition.detail_activity_shared_element_enter_transition);

<transition class="my.application.transitions.ElevationTransition"/>
</transitionSet>
my.application.transitions.ElevationTransition:
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
public class ElevationTransition extends Transition {
private static final String PROPNAME_ELEVATION = "my.elevation:transition:elevation";
public ElevationTransition() {
}
public ElevationTransition(Context context, AttributeSet attrs) {
super(context, attrs);
}

private void captureValues(TransitionValues transitionValues) {
Float elevation = transitionValues.view.getElevation();
transitionValues.values.put(PROPNAME_ELEVATION, elevation);
}
#Override

if (startValues == null || endValues == null) {
return null;
}
Float startVal = (Float) startValues.values.get(PROPNAME_ELEVATION);
Float endVal = (Float) endValues.values.get(PROPNAME_ELEVATION);
if (startVal == null || endVal == null || startVal.floatValue() == endVal.floatValue()) {
return null;
}
final View view = endValues.view;
ValueAnimator a = ValueAnimator.ofFloat(startVal, endVal);
a.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(ValueAnimator animation) {
view.setElevation((float)animation.getAnimatedValue());
}
});
return a;
}
}
TransitionHelper:
public class TransitionHelper {
public static void fixSharedElementTransitionForStatusAndNavigationBar(final Activity activity) {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)
return;
final View decor = activity.getWindow().getDecorView();
if (decor == null)
return;
activity.postponeEnterTransition();
decor.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
#Override
public boolean onPreDraw() {
decor.getViewTreeObserver().removeOnPreDrawListener(this);
activity.startPostponedEnterTransition();
return true;
}
});
}
public static void setSharedElementEnterTransition(final Activity activity, int transition) {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)
return;
activity.getWindow().setSharedElementEnterTransition(TransitionInflater.from(activity).inflateTransition(transition));
}
}
So what are the different parts here: We have two activities. During the transition, four views are transitioned between the activities.
Toolbar: like in the left gif the toolbar doesn't move with the rest of the content.
ListView element View -> becomes the content view of the DetailActivity
StatusBar and NavigationBar Background: If we don't add these views to the set of transitioned views they will fade out and back in during the transition. This however requires to delay the enter transition (see: TransitionHelper.fixSharedElementTransitionForStatusAndNavigationBar)
In the MainActivity the transitioned views are added to the Bundle that is used to start the DetailActivity. Furthermore the transitioned views need to be named (transitionName) in both activities. This can be done in the layout xml as well as programatically.
The default set of transitions, that is used during the shared element transition, affects different aspects of the view(for example: view bounds - see 2). However differences in the elevation of a view are not animated. This is why the presented solution utilizes the custom ElevationTransition.
you can also see this from google documentation:

Push above view up while animating slide up another view

I have following view inside my layout
<RelativeLayout
android:id="#+id/wrapper"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<LinearLayout
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true">
<!-- some child views here -->
</LinearLayout>
<LinearLayout
android:id="#+id/footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/header"
android:visibility="gone">
<!-- some other child views here -->
</LinearLayout>
</RelativeLayout>
The wrapper RelativeLayout is aligned to bottom of its parent. And initialy footer view is not displayed (View.GONE). When header view is tapped, then footer should be shown to user with slide up animation from bottom of screen and when user taps again footer should be slide down to bottom. When i start an slide up animation on footer view, it does not push header view simultaneously with animation. If i first set footer view visibility to View.INVISIBLE first and then start animation, header view is pushed up immediately (not together with animation or footer view), and footer view comes with animation.
Here is the code to call animation
footer.setVisibility(View.INVISIBLE);
Animation animation = AnimationUtils.loadAnimation(activity, R.anim.slide_up_from_bottom);
animation.setDuration(animDuration);
footer.startAnimation(animation);
footer.postDelayed(new Runnable() {
#Override
public void run()
{
footer.setVisibility(View.VISIBLE);
}
}, animDuration);
and this is the animation file content:
How can i make this animation to push header view, while footer view sliding up?
Hope i made myself clear. All i want is both views moves up/down together.
If i apply animation to wrapper view then it slides up from bottom (not from current location).

If you want your header to push along with footer animation, you can do it manually as follows
public class MainActivity extends Activity {
private LinearLayout header,footer;
private RelativeLayout wrapper;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
header = (LinearLayout) findViewById(R.id.header);
footer = (LinearLayout) findViewById(R.id.footer);
wrapper = (RelativeLayout) findViewById(R.id.wrapper);
header.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(footer.getVisibility() == View.VISIBLE){
int footerHeight = footer.getMeasuredHeight();
float initialWrapperY = wrapper.getY();
ObjectAnimator oa=ObjectAnimator.ofFloat(wrapper, "y", initialWrapperY,initialWrapperY+footerHeight);
oa.setDuration(400);
oa.start();
oa.addListener(new AnimatorListenerAdapter() {
public void onAnimationEnd(android.animation.Animator animation) {
footer.setVisibility(View.INVISIBLE);
};
});
}
else{
final float initialWrapperY = wrapper.getY();
footer.setVisibility(View.VISIBLE);
wrapper.setY(initialWrapperY);
ViewTreeObserver vto=wrapper.getViewTreeObserver();
vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
#Override
public boolean onPreDraw() {
wrapper.getViewTreeObserver().removeOnPreDrawListener(this);
final int footerHeight = footer.getMeasuredHeight();
ObjectAnimator oa=ObjectAnimator.ofFloat(wrapper, "y", initialWrapperY,(initialWrapperY-footerHeight));
oa.setDuration(400);
oa.start();
return true;
}
});
}
}
});
}
}

Android: How do I add a thin grey horizontal line on alert-dialog before the buttons?

I'm using android.app.AlertDialog that contains a ScrollView and inside (of course) some content.
Google shows in its material-guidelines a small grey line above the buttons when the content is larger than the visible space: http://www.google.com/design/spec/components/dialogs.html#dialogs-behavior
My alert-dialog doesn't have this grey line. How do I create this line?
I already tried a background for the ScrollView like this:
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="1dp"
android:color="#color/dark_transparent"/>
</shape>
But this created a line on top AND bottom. And it also appears when the content is smaller than the visible space, which looks ugly.

I found a solution for the grey line! :)
I found the solution how to show the grey line at all here: How to make a static button under a ScrollView?
For the check if I want to show it, I found the solution here: How can you tell when a layout has been drawn?
This is how my code looks like now:
This is my_material_dialog.xml:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ScrollView
android:id="#+id/myMaterialDialog_scrollView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:fillViewport="true">
<LinearLayout
android:id="#+id/myMaterialDialog_textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="5dp"
android:paddingLeft="26dp"
android:paddingRight="26dp"
android:paddingTop="15dp">
<!-- dynamically added content goes here -->
</LinearLayout>
</ScrollView>
<View
android:id="#+id/myMaterialDialog_lineView"
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_gravity="center_horizontal"
android:background="#15000000"
android:gravity="center_horizontal"
android:visibility="gone"/>
</LinearLayout>
And this is MyMaterialDialog.java:
public class MyMaterialDialog extends AlertDialog {
private Context context;
private ScrollView scrollView;
private LinearLayout textView;
private View lineView;
private boolean checkingLayout;
public MyMaterialDialog(final Context context) {
super(context);
this.context = context;
final View myMaterialDialog = getLayoutInflater().inflate(R.layout.my_material_dialog, null);
this.scrollView = (ScrollView) myMaterialDialog.findViewById(R.id.myMaterialDialog_scrollView);
this.textView = (LinearLayout) myMaterialDialog.findViewById(R.id.myMaterialDialog_textView);
this.lineView = myMaterialDialog.findViewById(R.id.myMaterialDialog_lineView);
final ViewTreeObserver vto = scrollView.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
if (checkingLayout) {
// avoid infinite recursions
return;
}
checkingLayout = true;
if (scrollView.canScrollVertically(1)) {
lineView.setVisibility(View.VISIBLE);
} else {
lineView.setVisibility(View.GONE);
}
checkingLayout = false;
}
});
setTitle(R.string.myMaterialDialog_title);
setText();
setView(myMaterialDialog);
show();
}
/**
* do request to webserver for texts
*/
private final void setText() {
final GetDialogTextRequest request = new GetDialogTextRequest();
final GetDialogTextResultHandler resultHandler = new GetDialogTextResultHandler(context, textView);
request.submit(resultHandler);
}
}
private final class GetDialogTextResultHandler extends DefaultRequestResultHandler<List<MyTextObject>> {
private final Context context;
private final LinearLayout textView;
private GetDialogTextResultHandler(final Context context, final LinearLayout textView) {
super(context);
this.context = context;
this.textView = textView;
}
#Override
public void handleResult(final List<MyTextObject> texts) {
setText(texts); // ... sets the content, can vary in size
}
}

Add something like this below your ScrollView:
<View android:layout_width="fill_parent"
android:layout_height="2px"
android:background="#90909090"/>
It should give you a slim greyish horizontal bar.

If you're using API 23+ (Android 6.0) using the following in scroll view will add the top and bottom indicators.
android:scrollIndicators="top|bottom"
If targeting older API's I looked into Google's Alert Dialog controller source code, and am using the following code:
private static void setScrollIndicators(ViewGroup root, final NestedScrollView content,
final int indicators, final int mask) {
// use it like this:
// setScrollIndicators(contentPanel, content, indicators,
// ViewCompat.SCROLL_INDICATOR_TOP | ViewCompat.SCROLL_INDICATOR_BOTTOM);
// Set up scroll indicators (if present).
View indicatorUp = root.findViewById(R.id.scrollIndicatorUp);
View indicatorDown = root.findViewById(R.id.scrollIndicatorDown);
if (Build.VERSION.SDK_INT >= 23) {
// We're on Marshmallow so can rely on the View APIsaa
ViewCompat.setScrollIndicators(content, indicators, mask);
// We can also remove the compat indicator views
if (indicatorUp != null) {
root.removeView(indicatorUp);
}
if (indicatorDown != null) {
root.removeView(indicatorDown);
}
} else {
// First, remove the indicator views if we're not set to use them
if (indicatorUp != null && (indicators & ViewCompat.SCROLL_INDICATOR_TOP) == 0) {
root.removeView(indicatorUp);
indicatorUp = null;
}
if (indicatorDown != null && (indicators & ViewCompat.SCROLL_INDICATOR_BOTTOM) == 0) {
root.removeView(indicatorDown);
indicatorDown = null;
}
if (indicatorUp != null || indicatorDown != null) {
final View top = indicatorUp;
final View bottom = indicatorDown;
if (content != null) {
// We're just showing the ScrollView, set up listener.
content.setOnScrollChangeListener(
new NestedScrollView.OnScrollChangeListener() {
#Override
public void onScrollChange(NestedScrollView v, int scrollX,
int scrollY,
int oldScrollX, int oldScrollY) {
manageScrollIndicators(v, top, bottom);
}
});
// Set up the indicators following layout.
content.post(new Runnable() {
#Override
public void run() {
manageScrollIndicators(content, top, bottom);
}
});
} else {
// We don't have any content to scroll, remove the indicators.
if (top != null) {
root.removeView(top);
}
if (bottom != null) {
root.removeView(bottom);
}
}
}
}
}
private static void manageScrollIndicators(View v, View upIndicator, View downIndicator) {
if (upIndicator != null) {
upIndicator.setVisibility(
ViewCompat.canScrollVertically(v, -1) ? View.VISIBLE : View.INVISIBLE);
}
if (downIndicator != null) {
downIndicator.setVisibility(
ViewCompat.canScrollVertically(v, 1) ? View.VISIBLE : View.INVISIBLE);
}
}
And XML looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<View
android:id="#+id/scrollIndicatorUp"
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/dim_white"
android:visibility="gone"
tools:visibility="visible" />
<android.support.v4.widget.NestedScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<... you content here>
</android.support.v4.widget.NestedScrollView>
<View
android:id="#+id/scrollIndicatorDown"
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/dim_white"
android:visibility="gone"
tools:visibility="visible" />
</LinearLayout>

On animation, part of listview is not showing

I have researched the questions thoroughly, but could not yet find the answer. Also, my excuses for my poor english since I am not a native speaker.
The problem: in my android layout we have a status_text with a listview below the status_text. When the status_text is touched, we animate a 'move down' on the status_text and listview so that only the first of the listview row is still on screen. The listview is now still usable.
When the status_text is touched again, we move the status_text and listview up so that the listview uses half of the screen.
The problem we are facing is that during the 'move up' only the first row is animated. After the 'move up' the other rows suddenly appear.
What we would like to have is a 'move up' where the previously hidden rows slide onto the screen.
The layout:
We are using this layout (slightly simplified to focus on the problem at hand):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_declareren_choose_verzekerden"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Dummy anchor to put top of listview in the middle of the screen -->
<RelativeLayout
android:id="#+id/anchor"
style="#style/anchor_status_container"
android:layout_centerVertical="true" >
</RelativeLayout>
<!-- Example image -->
<ImageView
android:id="#+id/my_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/footer"
android:adjustViewBounds="true"
android:contentDescription="#string/image_description"
android:scaleType="centerCrop"
android:src="#drawable/empty" />
<!-- Clickable text which moves up and down on click -->
<RelativeLayout
android:id="#+id/status_container"
style="#style/status_container"
android:layout_alignTop="#id/anchor"
android:background="#color/white" >
<TextView
android:id="#+id/status_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginRight="#dimen/spacing_sml"
android:layout_alignTop="#id/status_container" />
</RelativeLayout>
<!-- Listview which moves up and down with the status_container -->
<RelativeLayout
android:id="#+id/listView_container"
style="#style/padding_content_horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/status_container"
android:background="#color/white" >
<ListView
android:id="#+id/mylistView"
style="#style/myListviewStyle"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
android:divider="#null"
android:dividerHeight="0dp" />
</RelativeLayout>
<!-- Footer with buttons -->
<RelativeLayout
android:id="#+id/footer_button_container"
style="#style/footer"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:id="#+id/button_again"
style="#style/btn_secondary"
android:layout_width="wrap_content"
android:layout_alignParentLeft="true"
android:text="#string/opnieuw"
android:visibility="gone" />
<Button
android:id="#+id/button_next"
style="#style/btn_primary"
android:layout_width="wrap_content" />
</RelativeLayout>
</RelativeLayout>
And the code (again a bit simplified to show only the problem at hand. Some fade-in/out and rotations are removed):
// The code
#Override
public void onClick(View view)
{
int viewId = view.getId();
if (viewId == R.id.status_container)
{
// Someone clicked the text, move the statusbar (and so the listview) up or down
if (this.viewIsInUpperPosition)
{
startStatusAnimation();
}
}
}
private void startStatusAnimation()
{
if (animationIsRunning)
{
return;
}
setAnimationIsRunning(animValues.START);
// 0. Initialisation
final View statusContainer = (View) getView().findViewById(R.id.status_container);
final View listContainer = (View) getView().findViewById(R.id.listView_container);
final ListView listView = (ListView) getView().findViewById(R.id.myListView);
final View footerButtonContainer = (View) getView().findViewById(R.id.footer_button_container);
// 1. Calculate distance for animation
if (toggleViewDistance == 0)
{
int listViewContainerHeight = listContainer.getHeight();
int footerHeight = footerButtonContainer.getHeight();
int spaceForListView = listViewContainerHeight - footerHeight;
toggleViewDistance = spaceForListView;
}
// 2. Decide if the movement is up or down
float translationDistance = (viewIsInUpperPosition) ? toggleViewDistance : 0 - toggleViewDistance;
// 3. Create the animation
TranslateAnimation yMove = new TranslateAnimation(0, 0, 0, translationDistance);
yMove.setDuration(animValues.ANIMATION_Y_DURATION);
yMove.setInterpolator(new AccelerateDecelerateInterpolator());
// Do here something with scaling and rotating of other objects, not relevant for the question on StackOverflow
// 4. Actions after animation
yMove.setAnimationListener(new AnimationListener()
{
#Override
public void onAnimationEnd(Animation arg0)
{
// Fade de listView in als je van onderen naar boven animeert
if (!viewIsInUpperPosition)
{
// Do some fading, outside scope of question
}
// Create layout after the animation
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) statusContainer.getLayoutParams();
if (viewIsInUpperPosition)
{
// View was previously in upper position, now put the statusbar aligned with the footer
params = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ABOVE, footerButtonContainer.getId());
}
else
{
// View was previously in bottom position, so put it under the anchor
params = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_TOP, R.id.anchor);
}
}
statusContainer.setLayoutParams(params); // Set the new layout params
viewIsInUpperPosition = !viewIsInUpperPosition;
setAnimationIsRunning(animValues.END);
}
#Override
public void onAnimationRepeat(Animation arg0)
{
// Empty
}
#Override
public void onAnimationStart(Animation arg0)
{
// empty
}
});
// 5. Start the animation
statusContainer.startAnimation(yMove);
listContainer.startAnimation(yMove);
}
Any advice on how to have the rows of the listview 'slide in' on the screen? Much appreciated!

I figured it out. So I am answering my own question in case someone stumbles upon this question.
What needs to be done is that the listview is drawn off-screen. This can be forced by calling the measure- and layout-methods with the off-screen coordinates of the listview.
This fixed it for my code:
// 5a. Draw the listview off-screen
if (translationDistance < 0)
{
// Do this only when the listview is sliding up, e.g. sliding the window in.
int listViewContainerVerticalPos = listContainer.getTop(); // De positie van de listview
// The required height of the listview
int listContainerHeight = (int) Math.abs(translationDistance) + statusContainer.getHeight();
int measureWidth = View.MeasureSpec.makeMeasureSpec(listContainer.getWidth(), View.MeasureSpec.EXACTLY);
int measureHight = View.MeasureSpec.makeMeasureSpec(listContainerHeight, View.MeasureSpec.EXACTLY);
listContainer.measure(measureWidth, measureHight);
listContainer.layout(0, listContainerVerticalPos, listContainer.getMeasuredWidth(), listContainerVerticalPos
+ listContainerHeight);

I'm attempting to get the x/y of an imageview within a GridLayout but my log keeps showing X & Y: 0 0 any ideas?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/root" >
...
<GridLayout
android:id="#+id/gridLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:columnCount="3"
android:rowCount="5" >
...
<ImageView
android:id="#+id/fivetwo"
android:layout_width="75dp"
android:layout_height="75dp"
android:contentDescription="#string/gameboard"
android:gravity="center"
android:src="#drawable/tile"
android:layout_columnSpan="1"
android:layout_rowSpan="1" />
heres the java:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_level);
....
ImageView temp = (ImageView) findViewById(R.id.fivetwo);
int originalPos[] = new int[2];
temp.getLocationOnScreen( originalPos );
Log.i(TAG, "X & Y: " + originalPos[0] + " " + originalPos[1]);
...

Remember:getX() and getY()return 0 if components are not drawn yet (in onCreate(){} ).
To find out the position of a view as soon as it is ready:
Add a tree observer to the layout. This should return the correct position.
onCreate is called before the layout of the child views are done. So the width and height is not calculated yet. To get the height and width. Put this on the onCreate method
final ImageView temp = (ImageView) findViewById(R.id.fivetwo);
ViewTreeObserver vto = temp.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
temp.getViewTreeObserver().removeGlobalOnLayoutListener(this);
int x = temp.getX();
int y = temp.getY();
Log.v(TAG, String.format("X:%d Y:%d",x,y);
}
});

You need to wait for the callback when the layout has placed the children views. The code you are using returns 0 because the position is returned before the layout is placed. Use this code:
temp.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
getViewTreeObserver().removeGlobalOnLayoutListener(this);
int[] locations = new int[2];
temp.getLocationOnScreen(locations);
int x = locations[0];
int y = locations[1];
}
});
