Listview gets cut off when translating by y

Note: These are randomly generated addresses
Hey Guys, Learning Xamarin and I am trying to scroll my Frame Layour down and reveal a search bar for my list view. Here is what is happening:
I color coded my layouts to see if the sizes where a problem, but I dont think they are since my orange layout is plenty big to hold my two entries. Am I using the wrong layouts for this kind of application? I would appreciate any help!
Here is my translation code:
frameLayout.Animate().TranslationYBy(editSearch.Height).SetDuration(500).Start();
And my layout file:
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/swipeLayout">

android:layout_height="wrap_content"
android:id="#+id/editSearch"
android:hint="Search ZipCodes"
android:textColor="#000"/>
</FrameLayout>
</android.support.v4.widget.SwipeRefreshLayout>
EDIT:
Here is my OnOptionsItemSelected Code, where my animation is triggered.
public override bool OnOptionsItemSelected(IMenuItem item)
{
switch (item.ItemId)
{
case Resource.Id.action_search:
//search icon has been clicked
if (isAnimating)
return true;
else
{
if (animateBool)
{
//list view is up
animation anim = new animation(myListView, myListView.Height - editSearch.Height);
anim.Duration = 500;
myListView.StartAnimation(anim);
anim.AnimationStart += Anim_AnimationStartDown; //listener for when animation has started
anim.AnimationEnd += Anim_AnimationEndDown;
classSwipeRefresh.Animate().TranslationYBy(editSearch.Height).SetDuration(500).Start();
}
else
{
animation anim = new animation(myListView, myListView.Height + editSearch.Height);
anim.Duration = 500;
myListView.StartAnimation(anim);
anim.AnimationStart += Anim_AnimationStartUp; //listener for when animation has started
anim.AnimationEnd += Anim_AnimationEndUp;
classSwipeRefresh.Animate().TranslationYBy(-editSearch.Height).SetDuration(500).Start();
}
animateBool = !animateBool;
return true;
}
default:
return base.OnOptionsItemSelected(item);
}
}

Learning Xamarin and I am trying to scroll my Frame Layour down and reveal a search bar for my list view. Here is what is happening:
I use your code to test, but I have no problem when translating by Y in SwipeRefreshLayout__Refresh event.
public class MainActivity : AppCompatActivity
{
string[] items;
ListView listview1;
SwipeRefreshLayout swiplayout;
FrameLayout framelayout;
EditText edittext;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
Xamarin.Essentials.Platform.Init(this, savedInstanceState);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.activity_main);
listview1 = FindViewById<ListView>(Resource.Id.myListView);
swiplayout = FindViewById<SwipeRefreshLayout>(Resource.Id.swipeLayout);
framelayout = FindViewById<FrameLayout>(Resource.Id.frameLayout);
edittext = FindViewById<EditText>(Resource.Id.editSearch);
swiplayout.Refresh += Swiplayout_Refresh;
items = new string[] { "Vegetables", "Fruits", "Flower Buds", "Legumes", "Bulbs", "Tubers" };
listview1.Adapter = new ArrayAdapter(this, Android.Resource.Layout.SimpleListItem1, items);
}
private void Swiplayout_Refresh(object sender, EventArgs e)
{
framelayout.Animate().TranslationYBy(edittext.Height).SetDuration(500).Start();
}
}

If you want to filter ListView, I suggest you can use SearchView in Toolbar to filter listview data, please take a look this sample:

Translate Animation incorrect view move

I have 3 view objects(essentially ImageView's) with in a LinearLayout that in turn is within a RelativeLayout , The views are aligned within the LinearLayout as follows:
1 - 2 - 3 - -
The 3 views are wrapped under the Linear layout as demonstrated above.
Basically the idea is to get the side views(1st and 3rd views) move with animation to the place of the middle view onClick() .(so if 3rd view is clicked it should move to middle view's place and the middle moves right to the 3rd view's place.)
I implemented the translate animation as such that the 3rd view when clicked over 100dp to left and 2nd view moves to right, happens fine, but when I apply the translate animation on the onClick() of 1st view to make it move to right and 2nd to move to left then the 2nd and 3rd views both move collectively!! , This means the views are mapped next to each other automatically by the Android!!(note: that's why I used a LinearLayout so that alignment problems don't occur like 2nd view is aligned_below 1st view and aligned_left of 3rd view problems. )
also another problem is that though the views make a move land on another position that was originally belonging to the other view before the animated movement they still maintain the original view ID ?? For.Example that when 3rd view moves left to 2nd views place and 2nd mvoes to 3rd views place the onClick() still is mapped to their original location's?

Those 3 ImageViews with the names of ImageView1, ImageView01, ImageView02 are the one's I'm trying to animate.
Animation code:
final TranslateAnimation moveLefttoRight = new TranslateAnimation(0,
100, 0, 0);
final TranslateAnimation moveRightToLeft = new TranslateAnimation(0,
-100, 0, 0);
moveRightToLeft.setDuration(1000);
moveLefttoRight.setDuration(1000);
moveRightToLeft.setFillAfter(true);
moveLefttoRight.setFillAfter(true);
final ImageView image1 = (ImageView) findViewById(R.id.imageView1);
final ImageView image2 = (ImageView) findViewById(R.id.ImageView01);
final ImageView image3 = (ImageView) findViewById(R.id.ImageView02);
image1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
Toast.makeText(getApplicationContext(), "image1 clicked",
Toast.LENGTH_SHORT).show();
}
});
image2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
Toast.makeText(getApplicationContext(), "image2 clicked",
Toast.LENGTH_SHORT).show();
image2.startAnimation(moveLefttoRight);
image1.startAnimation(moveRightToLeft);
}
});
image3.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
Toast.makeText(getApplicationContext(), "image3 clicked",
Toast.LENGTH_SHORT).show();
image2.startAnimation(moveLefttoRight);
image3.startAnimation(moveRightToLeft);
}
});

Translate animation doesn't actually move the view, it just makes it look like that. You have to set the params before the end of the animation so that the button moves as well.example
with the other issue can you post your xml layout file? do you use weights in the imageviews?

I ended up using ObjectAnimator builtin animating API and this moves the view's position permanently to the co-ords. requested.

LinearLayout larger than screen

I am trying to create a horizontal LinearLayout which is wider than the screen of the device. It contains a Button which will move the layout to view the part outside the screen when it is clicked. The problem is that android is not creating the part outside the screen, so when I press the button, the view moves to show black screen where the remaining view should have been.
My code-
MainActivity.java
public class MainActivity extends BaseGameActivity implements OnClickListener {
private Context mContext;
private int mScreenHeight;
private int mScreenWidth;
private LinearLayout mViewContainer;
private View mTransparentContainer;
private Button mSliderBtn;
private View mSlidingView;
private View mHomeView;
private int mSlidingWidth;
private boolean mIsSlidingMenuVisible = false;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mContext = getApplicationContext();
mScreenHeight = UserScreen.getHeight(mContext);
mScreenWidth = UserScreen.getWidth(mContext);
mSlidingWidth = (int) (getResources().getDimension(R.dimen.sliding_menu_offset) + 0.5f);
mViewContainer = new LinearLayout(mContext);
mViewContainer.setOrientation(LinearLayout.HORIZONTAL);
mViewContainer.setLayoutParams(new LinearLayout.LayoutParams(mScreenWidth + mSlidingWidth, mScreenHeight));
setContentView(mViewContainer);
LinearLayout homeContainer = new LinearLayout(mContext);
LinearLayout.LayoutParams homeContainerParams = new LinearLayout.LayoutParams(mScreenWidth, LayoutParams.MATCH_PARENT);
mHomeView = getLayoutInflater().inflate(R.layout.activity_main, homeContainer);
mHomeView.setBackgroundColor(0x80ffffff);
mViewContainer.addView(homeContainer, homeContainerParams);
LinearLayout slidingContainer = new LinearLayout(mContext);
LinearLayout.LayoutParams slidingContainerParams = new LinearLayout.LayoutParams(mSlidingWidth, LayoutParams.MATCH_PARENT);
mSlidingView = getLayoutInflater().inflate(R.layout.slider_menu, slidingContainer);
mViewContainer.addView(slidingContainer, slidingContainerParams);
initUi();
// other code
}
public void initUi() {
mSliderBtn = (Button) mHomeView.findViewById(R.id.button_slider);
mSliderBtn.setOnClickListener(this);
mTransparentContainer = mHomeView.findViewById(R.id.transparent_container);
mTransparentContainer.setOnClickListener(this);
// other code
}
#Override

switch (view.getId()) {
case R.id.button_slider:
mSliderBtn.setEnabled(false);
mIsSlidingMenuVisible = true;
mTransparentContainer.setVisibility(View.VISIBLE);
mTransparentContainer.bringToFront();
tableMoveLeft(mViewContainer, mSlidingWidth);
break;
case R.id.transparent_container:
mSliderBtn.setEnabled(true);
mIsSlidingMenuVisible = false;
mTransparentContainer.setVisibility(View.GONE);

My Output on clicking the button
Using a ScrollView is not a solution because I dont want the user to freely scroll the view, and also there is a ViewPager in the main layout which will conflict with it. Please help. Thanks.

Android officially introduced sliding panel menu by introducing a newer concept called Navigation Drawer. Most of the time Sliding Menu (Navigation Drawer) will be hidden and can be shown by swiping the screen from left edge to right or tapping the app icon on the action bar.
For example, the following layout uses a DrawerLayout with two child views: a FrameLayout to contain the main content (populated by a Fragment at runtime), and a ListView for the navigation drawer.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
for additional info about NavigationDrawer, please take a look into these links :

The problem was that the layout with size larger than screen size was set as the root container of the activity. I don't know what was the problem caused by that, but to fix it-
#Override
public void onCreate(Bundle savedInstanceState) {
super(savedInstanceState);
LinearLayout rootContainer = new LinearLayout(mContext);
setContentView(rootContainer);
// other code
rootContainer.addView(mViewContainer);
}
Any explanations of why having a root view larger than screen size created a problem are welcome :)

Translate animation is behind other layout

I have four linear layouts in my screen.
The first layout contain a textview.
I'm trying to move my textView to the the fourth layout of the right with a translate animation.
But when i do that the text view move behind the other layout and if i move my layout from the fourth layout of the right to the first at the left it's ok.
Im my xml i have put : in all layouts
android:clipChildren="false"
image
Can you help me ?
Thank you

Use setZAdjustment to put your View in front of the other Views.
http://developer.android.com/reference/android/view/animation/Animation.html#setZAdjustment%28int%29

Pre-Kitkat :
yourLayout.bringToFront();
((View)yourLayout.getParent()).requestLayout();
((View)yourLayout.getParent()).invalidate();
KitKat :
yourLayout.bringToFront();

Android linear layout construction starts from first element from the beginning. So any element defined first will be created and then rest, so no matter what you do, you cannot achieve with linear layout. Try with relative layout
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/testAnimTranslate"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:gravity="center_vertical"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="30dp"
android:layout_height="70dp"
android:background="#0000dd"
android:orientation="vertical" />
<LinearLayout
android:layout_width="30dp"
android:layout_height="70dp"
android:layout_alignParentBottom="true"
android:background="#0dd0dd"
android:orientation="vertical" />
<LinearLayout
android:layout_width="30dp"
android:layout_height="70dp"
android:layout_alignParentBottom="true"
android:background="#ddd0dd"
android:orientation="vertical" />
<LinearLayout
android:layout_width="30dp"
android:layout_height="70dp"
android:layout_alignParentBottom="true"
android:background="#44d0dd"
android:orientation="vertical" />
</LinearLayout>
<TextView
android:id="#+id/textAnimate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#id/testAnimTranslate"
android:layout_alignTop="#id/testAnimTranslate"
android:layout_toLeftOf="#id/testAnimTranslate"
android:gravity="center"
android:background="#00000000"
android:text="qweqwew" />
</RelativeLayout>
Define your translate anim in anim folder or programatically. make sure to add
LinearInterpolator
setFillAfter to true
and start the anim

I think you create the view in the code, so you should add setClipChildren(false)
in your constructor too.

Look at the docs:
ZORDER_TOP: Requests that the content being animated be forced on top of all other content for the duration of the animation.
Please check that setFillAfter(true) does not match this usage.
Does it help?

The main problem with what you are trying to do, is that you want to draw a View outside of its parent. It goes behind the other LinearLayouts because they are drawn after the LinearLayout parent of the View. Even if it is brought to the front, it seems that only relates to children within a single parent?
If you look at how Fragment animations work, you need to recreate the Fragment to translate a from one Frame into another. You also need two separate animations.
BlackBeard's solution will work because it makes the TextView a child of the outermost parent and declares it last. This means the TextView is drawn after everything else and therefore will be drawn on top of everything else.
This doesn't achieve what I think you are trying to do. If you want the TextView to belong to its destination LinearLayout after the animation you'll need to recreate the TextView and add it to the LinearLayout in the correct position in the hierarchy. You'll also need a second animation to move the new TextView into its position.
If done properly the animations should overlay each other perfectly and if in a LinearLayout one or the other of the animated Views will pass on top of everything else.

EDIT: You could also declare the TextView in xml and inflate it to get rid of all the code initialising it.

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"

<!-- Dummy anchor to put top of listview in the middle of the screen -->

<!-- Example image -->

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);
}
