How to programmatically display a view in center of another view - android

I have a buttonView1 and a customView1 that only draws a small circle. in my main_layout only buttonView1 is visible.
How can I programmatically display customView1 in center of buttonView1 when button is clicked.
attention: we dont want to change button background. we want to show a new view (customView or any other view like editText) on another view (button) when button is pressed.
layout code:
<RelativeLayout 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"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<Button
android:id="#+id/buttonView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="102dp"
android:layout_marginTop="86dp"
android:text="#string/button_text" />
</RelativeLayout>
activity code
///...
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mButton = (Button)findViewById(R.id.buttonView1);
mButton.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.buttonView1:
// do sth here
break;
default:
break;
}
}
///...

RelativeLayout.LayoutParams layoutParams =
(RelativeLayout.LayoutParams)positiveButton.getLayoutParams();
layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
yourView.setLayoutParams(layoutParams);

public void MoveView() {
float a = parent_view.getWidth() / 2;
final ValueAnimator positionAnimator =
ValueAnimator.ofFloat(current_view.getX(), a);
positionAnimator.setInterpolator(new AccelerateDecelerateInterpolator());
positionAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(ValueAnimator animation) {
float x = (Float) positionAnimator.getAnimatedValue();
current_view.setX(x);
}
});
positionAnimator.setDuration(100);
positionAnimator.start();
}
parent_view is the view in whose center you would like to place your current_view.
Hope that Helps.

Expand/collapse animation in CardView

I try to do something like this :
I managed to do my cardViewAdapter but I block to enlarge my cards. I resumed the code of this response (Here the name of the class is : CardsAnimationHelper) to do the animation but it's superimposed.
Before expand:
After expand:
I solved the problem above but if on my cardView I display 10 elements at the same time for a list of 50. If I expand the first, the numbers 11,21,31,41 will also expand. Do you have a trick for this not to happen?
I have reflected, it makes no sense to me. Just before my OnClick method I display a textview where the text is the position. But when I click id are correct so that would mean that when I click it detects the click on several cards. I think I may have a problem with a view in my OnClickListener

I did not understand what you meant by displaying 10 elements out of 50. However, you can achieve the expand/collapse simply by showing/hiding the views and providing android:animateLayoutChanges="true" into the child layout of the CardView. Here is an example:
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:animateLayoutChanges="true"
android:padding="16dp"
android:orientation="vertical">
<TextView
android:id="#+id/hello"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"/>
<TextView
android:id="#+id/hello2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
android:visibility="gone"/>
<TextView
android:id="#+id/hello3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
android:visibility="gone"/>
</LinearLayout>
</android.support.v7.widget.CardView>
And corresponding controller:
TextView t1 = (TextView) findViewById(R.id.hello);
final TextView t2 = (TextView) findViewById(R.id.hello2);
final TextView t3 = (TextView) findViewById(R.id.hello3);
t1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (t2.getVisibility() == View.GONE) {
t2.setVisibility(View.VISIBLE);
t3.setVisibility(View.VISIBLE);
} else {
t2.setVisibility(View.GONE);
t3.setVisibility(View.GONE);
}
}
});
Tapping on the first TextView will collapse and expand the CardView along with the animation.
You'll need to create a custom class that extends CardView. Inside that class put the following methods:
public void expand() {
int initialHeight = getHeight();
measure(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
int targetHeight = getMeasuredHeight();
int distanceToExpand = targetHeight - initialHeight;
Animation a = new Animation() {
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
if (interpolatedTime == 1){
// Do this after expanded
}
getLayoutParams().height = (int) (initialHeight + (distanceToExpand * interpolatedTime));
requestLayout();
}
#Override
public boolean willChangeBounds() {
return true;
}
};
a.setDuration((long) distanceToExpand);
startAnimation(a);
}
public void collapse(int collapsedHeight) {
int initialHeight = getMeasuredHeight();
int distanceToCollapse = (int) (initialHeight - collapsedHeight);
Animation a = new Animation() {
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
if (interpolatedTime == 1){
// Do this after collapsed
}
Log.i(TAG, "Collapse | InterpolatedTime = " + interpolatedTime);
getLayoutParams().height = (int) (initialHeight - (distanceToCollapse * interpolatedTime));
requestLayout();
}
#Override
public boolean willChangeBounds() {
return true;
}
};
a.setDuration((long) distanceToCollapse);
startAnimation(a);
}
Note that when you collapse it, you'll need to pass along the height you want it to be when collapsed. The height when expanded is set to WRAP_CONTENT.
I've also added if/else statements that will run when the animation has completed.
Good luck!

custom drag and drop

i am a begginer android develpoer and i am tring to build a small soiltare game.
for dragging the cards i implemented a custom viewgroup which is a "DragContainer" from one of the questions here.
my problem is that when i drag a linear layout. my linear layout holds the cards
with a - margin (to overlap the cards) but when i start the drag the dragged "shadow" is my layout without the margin.
here is an example
this is the start of the activity, the left is a linear layout with two children and also the right
when i start the drag this is what i see
as you can see the dragged "shadow" is bigger(without the - margin)
this is the code for the custom drag container(only the stuff that matters):
public boolean startDragChild(View child, ClipData data,
Object myLocalState, int flags) {
setDragTarget(child);
return child.startDrag(data, new EmptyDragShadowBuilder(child),
myLocalState, flags);
}
private void setDragTarget(View v) {
target = v;
onSetDragTarget(v);
}
/**
* this is similar to the constructor of DragShadowBuilder
*
* #param v
*/
protected void onSetDragTarget(View v) {
}
#Override
protected void dispatchDraw(Canvas canvas) {
super.dispatchDraw(canvas);
if (mOnDrag && target != null) {
canvas.save();
drawDragShadow(canvas);
canvas.restore();
}
}
protected void drawDragShadow(Canvas canvas) {
int h = target.getHeight();
int w = target.getWidth();
canvas.translate(mDragX - w / 2, mDragY - h / 2);
target.draw(canvas);
}
I guess akon does not require the explanation but I would like to tell to the audience of the question.
The margins inside the LinearLayout should be intact as you would be moving ViewGroup itself, so it's children won't have any issue with it's design,
Code is also available on the Github
public class DragTestTwoActivity extends AppCompatActivity {
private LinearLayout source_linearLayout;
private LinearLayout destination_linearLayout;
private static final String TAG = "DragTestTwoActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {

source_linearLayout = (LinearLayout) findViewById(R.id.DragTestTwoActivity_Source_LinearLayout);
destination_linearLayout = (LinearLayout) findViewById(R.id.DragTestActivityActivity_Destination_LinearLayout);
// source_linearLayout.setOnDragListener(new MyDragListener());
destination_linearLayout.setOnDragListener(new MyDragListener());
source_linearLayout.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
ClipData data = ClipData.newPlainText("", "");
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(source_linearLayout);
source_linearLayout.startDrag(data, shadowBuilder, source_linearLayout, 0);
return true;
}
});
}
private class MyDragListener implements View.OnDragListener {
#Override
public boolean onDrag(View v, DragEvent event) {
switch (event.getAction()) {
case DragEvent.ACTION_DRAG_STARTED:
Log.d(TAG, "Drag has started");
break;

Output
this is how it would look like...
Of course, you can use standart views for this purpose but it is irrational. It will better to use SurfaceView (or if you know OpenGL GLSurfaceView).

Scrolling of ListView getting disabled

I have a LinearLayout which contains an image and a ListView. In my code I'm trying to set the layout params of the LinearLayout. Unfortunately, when I do that I'm no longer able to scroll in my ListView. Here are the relevant snippets:
private class ExpandAnimation extends Animation {
private final View mContent;
private final int mStartHeight;
private final int mDeltaHeight;
public ExpandAnimation(int _startHeight, int _endHeight, View _content) {
mStartHeight = _startHeight;
mDeltaHeight = _endHeight - _startHeight;
mContent = _content;
}
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(mContent.getLayoutParams());
lp.height = (int) (mStartHeight + mDeltaHeight * interpolatedTime);
mContent.setLayoutParams(lp);
if(interpolatedTime == 1.0f) {
lp = new LinearLayout.LayoutParams(mListLayout.getLayoutParams());
View mainLayout = mActivity.findViewById("id goes here");
lp.height = mainLayout.getBottom();
mListLayout.setLayoutParams(lp); // <-- Calling setLayoutParams here
}
}
#Override
public boolean willChangeBounds() {
return true;
}
}
How I create my animation Animation a = new ExpandAnimation(initialHeight, targetHeight, v); and the layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/some_id_1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:orientation="vertical" >
// layout
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#id/some_id_2"
android:orientation="vertical" >
// more layout
<LinearLayout
android:id="#+id/some_id_3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
// even more layout
<ListView
android:id="#+id/some_id_4"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
Can anyone shed some light on this?

android - onClickListener causes a reset of my animation

I have an Activity with some elements like ImageView, Button, ToggleButton, ... . And a subview (LinearLayout) that contains an HorizontalScrollView of ImageView.
The subview is an element that I want to hide / show with an animation.
My animation works successfully. But when I touch a ToggleButton or I apply a Filter, the subview is reseted and back to its origin position.
I have deduce that the subview is replaced in its origin when an element of the view visually change.
But I don't understand why...
The Activity class
public class CameraActivity extends Activity implements PictureCallback

flashButton = (ToggleButton)findViewById(R.id.button_flash);
filterScrollButton = (Button)findViewById(R.id.button_open_filters);
filterScrollView = (LinearLayout)findViewById(R.id.camera_scroll_filters);
filterScrollViewLayout = (LinearLayout)findViewById(R.id.camera_scroll_filters_layout);
}
...
private void initScrollFilters()
{
String[] filters = getResources().getStringArray(R.array.array_filters);
for (final String string : filters)
{
ImageView v = new ImageView(CameraActivity.this);
int imageFilterId = -1;
if (string != null && !string.isEmpty())
{
final int imageId = getResources().getIdentifier("#drawable/filter_" + string, null, getPackageName());
imageFilterId = getResources().getIdentifier("#drawable/filter_" + string, null, getPackageName());
v.setImageDrawable(getResources().getDrawable(imageId));
}
final int finalImageFilterId = imageFilterId;
v.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View view) {
Log.d(string + " filter image is touched");
CameraActivity.this.cameraManager.setImageFilter(finalImageFilterId); // Apply the new filter into filterImageView
}
});
filterScrollViewLayout.addView(v, 100, 100);
}
}
private void initListeners()
{
// Flash
flashButton.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
{
// camera parameters is changed
}
});
// Filter scroll view
filterScrollButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
Log.d("You click the filter scroll button men!!");
final float direction = (CameraActivity.this.filtersIsOpened) ? -1 : 1;
final float yDelta = -100;
final Animation animation = new TranslateAnimation(0, 0, 0, yDelta * direction);
animation.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {}
#Override
public void onAnimationRepeat(Animation animation) {}
#Override
public void onAnimationEnd(Animation animation)
{
TranslateAnimation anim = new TranslateAnimation(0.0f, 0.0f, 0.0f, 0.0f);
anim.setDuration(1);
CameraActivity.this.filterScrollView.startAnimation(anim);
int top = (int) (CameraActivity.this.filterScrollView.getTop() + (yDelta * direction));
CameraActivity.this.filterScrollView.setTop(top);
}
});
animation.setDuration(500);
CameraActivity.this.filterScrollView.startAnimation(animation);
CameraActivity.this.filtersIsOpened = ! CameraActivity.this.filtersIsOpened;
}
});
}
...

Changing EditText height and width on Runtime with some animation

I have Four EditText with different background.
It looks like this:
I want to cover full screen when a EditText is selected with That EditText. For that I need to change the EditText width and height with some animation on Runtime.
When selected It should look like this:
How can I change EditText size with animation on Runtime ?
ANSWER UPDATED :
use this code in drawable/animation_sample.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" android:shareInterpolator="false">
<translate android:fromXDelta="0%" android:toXDelta="100%" android:fromYDelta="0%" android:toYDelta="0%" android:duration="500" />
And set the animation to the edit text using :
Animation anim=AnimationUtils.loadAnimation( this, R.anim.righttoleft);
editText = (EditText)findViewById(R.id.editText1);
Display display = getWindowManager().getDefaultDisplay();
int width=display.getWidth();
int height = display.getHeight();
editText.setWidth(width);
editText.setHeight(height);
editText.startAnimation(anim);
I'm not sure if it can be done with Animations. In android view takes all space before animation finished, so you will see that other editTexts disappears and selected one slowly increasing. Here is rough example how to do it without standart animations, but changing weights in separate thread:
layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

I do not know if this is possible for you, but in this example you can add some more movements quite easy.
I do not recommend use it production, if only you have some other options.
I have tried to explain my Logic for your problem...i hope so it would work for you..
EditText editText = new EditText(this);
editText.setOnClickListener(new OnClickListener() {
public void onClick(){
// Before getSize was introduced (in API level 13), you could use
// the getWidth and getHeight methods that are now deprecated:
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();
editText.setWidth(width);
editText.setHeight(height);
}
}
