Setting ImageView and TextView at predefined XY coordinates - Xamarin Android

I have a Greeting Card activity where one can place Text and Image at desired locations by moving ImageView and TextView using Touch events. After moving to location I want to save its position and use same for other greetings. But neither view.GetX(), view.GetY() nor view.Left, view.Top is working.
I can capture the XY after moving but when using same XY coordinates on SetX & SetY or Left & Top the view is placed at weird locations.
This is my XML layout and using Touch even I move imgV1, txtName and txtSignature.

TextView touch event
private void TxtName_Touch(object s, TouchEventArgs e)
{
TextView v = (TextView)s;
if (e.Event.Action == MotionEventActions.Move)
{
v.SetX(e.Event.RawX - v.Width / 2.0f);
v.SetY(e.Event.RawY - v.Height / 2.0f);
}
}
Any suggestions ?

Modify your code as below ,it works fine on my side .
float dX, dY;
private void TextView_Touch(object sender, Android.Views.View.TouchEventArgs e)
{
TextView view = (TextView)sender;
int X = (int)e.Event.RawX;
int Y = (int)e.Event.RawY;
switch (e.Event.Action)
{
case MotionEventActions.Down:
dX = view.GetX() - X;
dY = view.GetY() - Y;
break;
case MotionEventActions.Move:
view.Animate().X(X + dX).Y(Y + dY).SetDuration(0).Start();
break;
}
}

ImageView background in not setting multiple times

I am working on an android project, in which I need to set ImageView
background (ascending icon and descending icon) multiple times. to do
this I am doing it with a clicking variable like:
sortBookedOnLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
pickUpImage.setBackgroundResource(R.drawable.ascending);
vouchredImage.setBackgroundResource(R.drawable.ascending);
cancledImage.setBackgroundResource(R.drawable.ascending);
if(Constant.bookedOn == 1) {
Log.d(TAG, "FliteronClick:1 ");
bookedonImage.setImageDrawable(mContext.getResources().getDrawable(R.drawable.ascending_active));
// int ascending_active_b = R.drawable.ascending_active;
// bookedonImage.setBackgroundResource(ascending_active_b);
// bookedonImage.setImageDrawable(mContext.getResources().getDrawable( R.drawable.ascending_active));
// bookedonImage.setBackground(mContext.getResources().getDrawable(R.drawable.ascending_active));
// ivPickUpTxt.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ascending_active, 0);
Constant.bookedOn = 2;
}else if(Constant.bookedOn == 2){
Log.d(TAG, "FliteronClick:2 ");
bookedonImage.setImageDrawable(mContext.getResources().getDrawable(R.drawable.decending_active));
// bookedonImage.setImageResource(android.R.color.transparent);
// int decending_active_b = R.drawable.decending_active;
// bookedonImage.setBackgroundResource(decending_active_b);
// bookedonImage.setImageDrawable(mContext.getResources().getDrawable( R.drawable.decending_active));
// ivPickUpTxt.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.decending_active, 0);
Constant.bookedOn = 1;
}
}
}
});
And My Xml layout is just like:
<LinearLayout
android:id="#+id/sortBookedOnLayout"
android:orientation="horizontal"
android:background="#color/white"
android:weightSum="2"
android:layout_width="match_parent"

android:layout_height="match_parent"
android:background="#drawable/ascending"
/>
</LinearLayout>
</LinearLayout>
Screenshot of my layout.
in this image i am going to click on BookedOn layout.
And my targetSdkVersion 25
I have tried it multiple ways as I commented but image icon is not
reflecting on imageView. any help will be appreciable.Thanks.

Try this:
qImageView.setBackgroundResource(R.drawable.thumbs_down);
and add android:scaleType:fitxy
<ImageView
android:id="#+id/booedOnImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitxy"
android:background="#drawable/ascending"/>
(or) Try programmatically
imgview.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
Here's a thread that talks about the differences between the two methods.
I Understand your problem...You are not set the width of the LinearLayout
<LinearLayout
android:layout_weight=".2"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<ImageView
android:id="#+id/booedOnImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/abc_btn_rating_star_off_mtrl_alpha"
/>
</LinearLayout>

TranslateAnimation move tomake other views appear

I'm using a TranslateAnimation to make a fragment (GoogleMap) sliding down to give space to an EditText and a TextView to be visible.
so I used this:
text: TextView
edit: EditText
MapLayout: a LinearLayout that contains the Map
Animation animation = new TranslateAnimation(
MapLayout.getX(), MapLayout.getY(),MapLayout.getY(), text.getHeight()+edit.getHeight());
The problem is that I can't make the slide because text.getHeight()+edit.getHeight() returns 0 so there's no slide!
I tried using a number (100 for exemple), the slide is made, but it's different between the devices, I tested on a Galaxy S3 and the slide is not complete, there's still a part of the EditText which is not visible, as for the emulator it worked ok.
When I tried to make the number a bit bigger, so the slide will be longer (200 for exemple), well... the slide was good for the S3, but i was big for the emulator.
So what I want to know is that if there's any way to make the slide move to a point, without depending on the device, I mean without using pixels; so the slide will work perfectly in any device/
I hope that my problem is clear.
Thank you
Update: I don't if this will help, I added a Toast message, show the height of the EditText and the TextView, in the Emulator it says: 85 and in the S3 it says 181
So yeah, I need to make the map slide down in any device like I said
MainActivity:
protected Animation animation;
protected LinearLayout MapLayout;
protected EditText edit;
protected TextView text;
MapLayout = (LinearLayout)findViewById(R.id.MapLayout);
edit = (EditText)findViewById(R.id.Recherche);
text = (TextView)findViewById(R.id.CaptionRecherche);
Toast.makeText(context, "Height: "+(edit.getHeight()+text.getHeight()), 1000).show();
animation = new TranslateAnimation(MapLayout.getX(), MapLayout.getY(), MapLayout.getY(), text.getHeight()+edit.getHeight());
animation.setDuration(1000);
animation.setFillAfter(true);
MapLayout.startAnimation(animation);

As a part of my application, I have a status bar which contains some text. This status bar is hidden until the user clicks a button at which point it slides down (hiding the topmost content of the layout below).
The code I use to get the correct height of the hidden status bar:
private int hiddenStatusHeight;
private int currentStatusBarHeight;
private void getStatusBarHeight() {
final ViewTreeObserver observer = hiddenStatus.getViewTreeObserver();
observer.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#SuppressLint("NewApi") #SuppressWarnings("deprecation") #Override public void onGlobalLayout() {
hiddenStatus.measure(MeasureSpec.UNSPECIFIED,
MeasureSpec.UNSPECIFIED);
hiddenStatusHeight = hiddenStatus.getMeasuredHeight();
currentStatusBarHeight = statusBar.getHeight();
ViewTreeObserver obs = hiddenStatus.getViewTreeObserver();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
obs.removeOnGlobalLayoutListener(this);
} else {
obs.removeGlobalOnLayoutListener(this);
}
}
});
}
The code that is executed when the button is clicked:
private OnClickListener ExpandClickListener = new OnClickListener() {
#Override public void onClick(View v) {
boolean isExpanded = (Boolean) expandButton
.getTag(R.id.TAG_EXPANDED);
int originalHeight = (Integer) expandButton
.getTag(R.id.TAG_ORIGINAL_HEIGHT);
if (isExpanded) {
expandButton.setTag(R.id.TAG_EXPANDED, false);
expandButton.setImageResource(R.drawable.ic_action_down);
// statusBar.setLayoutParams(new FrameLayout.LayoutParams(
// LayoutParams.MATCH_PARENT, originalHeight));
Log.d(TAG, "Collapsing to " + originalHeight);
ValueAnimator va = ValueAnimator.ofInt(currentStatusBarHeight,
originalHeight);
va.setDuration(500);
va.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
Integer value = (Integer) animation.getAnimatedValue();
statusBar.getLayoutParams().height = value.intValue();
statusBar.requestLayout();
}
});
va.start();
} else {
expandButton.setTag(R.id.TAG_EXPANDED, true);
expandButton.setImageResource(R.drawable.ic_action_collapse);
currentStatusBarHeight = originalHeight + hiddenStatusHeight;
// statusBar.setLayoutParams(new FrameLayout.LayoutParams(
// LayoutParams.MATCH_PARENT, currentStatusBarHeight + 15));
Log.d(TAG, "Expanding to " + originalHeight + "+"
+ hiddenStatusHeight + "=" + currentStatusBarHeight);
ValueAnimator va = ValueAnimator.ofInt(originalHeight,
currentStatusBarHeight);
va.setDuration(500);
va.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
Integer value = (Integer) animation.getAnimatedValue();
statusBar.getLayoutParams().height = value.intValue();
statusBar.requestLayout();
}
});
va.start();
}
}
};

Hope some of this may be helpful to you.
Just to mention it, I have asked a similar question where the visible layout is pushed downwards as the menu expands. So have a look at that if you rather want this behaviour: How to animate a slide in notification view that pushes the content view down
Happy coding

WRAP_CONTENT not working after dynamically adding views

I'm trying to create a fragment that lays out a series of custom views dynamically. The main content for this layout is a RelativeLayout nested in a LinearLayout (to center it horizontally), nested in a ScrollView.
The RelativeLayout has a few TextViews and a 9 patch ImageView that is meant to scale with the dynamically added custom views. However, the image (achievements_bgImageView below) is ending up as the size of the screen, and is not respecting the size of its parent RelativeLayout even after I've added the appropriate amount of custom views. The image scales fine when I manually set the size of achievements_mainLayout (see the commented out lines below), but does nothing if I try to let that RelativeLayout's wrap_content handle its own sizing.
The ScrollView IS respecting the size of the RelativeLayout, as all the content is present, it's simply the imageView that isn't stretching to match the content at this point.
Any help would be appreciated... My manual calculations don't seem to be good enough to account for different devices, despite the fact I'm accounting for screen density and I'm manually forcing the RelativeLayout to a constant width.
It's worth noting that the measured size of the RelativeLayout is always equal to the height of the screen, regardless of whether or not the sum of its content is greater or less than that height. So, essentially, WRAP_CONTENT is simply not doing what it's supposed to be doing. I have nothing referencing any edge of of the RelativeLayout, so circular dependencies shouldn't be a problem.

Try calling requestLayout on the children.
I recently had a similar problem and was similarly frustrated that things like invalidate and requestLayout seemed to do nothing. What I didn't understand is that requestLayout doesn't propagate down to its children; it propagates up to its parents. To re-measure something that was previously measured, I had to call requestLayout on the View that changed rather than the View I actually wanted to resize.

Android does NOT refresh layout of views with "wrap_content" once it has been displayed.
So if you add a child view, or modify the content dynamically, you're screwed.
I do agree that this is a nightmare and a real flaw in Android UI!
To solve that, I've written a static class that recomputes the sizes and forces the update of the layout for the views with "wrap_content"
The code and instructions to use are available here:
https://github.com/ea167/android-layout-wrap-content-updater
Enjoy!

A simple way to update the size of a View with WRAP_CONTENT is change the visibility to GONE and back to the old visibility.
int visibility = view.getVisibility();
view.setVisibility(View.GONE);
view.setVisibility(visibility);
TESTED ON ANDROID JELLY BEAN IN 2014
MAY NOT WORK ON NEWER ANDROID VERSIONS

Ok, I solved this by manually measuring the RelativeLayout immediately after adding all the views and setting the mainLayoutParams height explicitly. I wish I was smarter and knew why it wasn't automatically doing this correctly in the first place, but oh well.
...
mainLayout.measure(0, 0);
ViewGroup.LayoutParams mainLayoutParams = mainLayout.getLayoutParams();
mainLayoutParams.height = mainLayout.getMeasuredHeight() + 10;
...

I encountered same issue when working with LinearLayout which has wrap_content and one child as TextView match_parent.
To fix this I did this:
Remove the TextView programatically and then add it again.
linearLayout.removeView(textView)
linearLayout.addView(textView)
I know it sounds stupid but it works.
In my case calling invalidate didn't work, only this worked.
Depending on your implementation you need to take care of view index inside its parent

You are getting this problem because you set your layout first and then add its content dynamically.
You are telling the layout to wrap to the content that is not yet their. Try using your layout inflater after you have grabbed your content

You should use NestedScrollView Instead of simple scrollview.

Set the layout parameters again(width and height), right after adding the view. This worked for me.
if the parent View is a FrameLayout, then do something like this:
ImageView view = (ImageView) LayoutInflater.from(activity).inflate(R.layout.image_object_view, null);
imageObjectsHolder.addView(view);
FrameLayout.LayoutParams param = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
view.setLayoutParams(param);

My problem was fixed by seting layout_width to some specific dp.
So changing from "wrap content" or "match parent"
to
android:layout_width="300dp"
will fix it, but i know it's not solution for all cases. But maybe you have some parent width, so you can apply the width to the textview.
height leave with wrap_content, and it will work.

Detect finger leave of image button in android

I have an image button, i am trying to record an audio on touch of a button & when user leaves a button i stop recording.I am successfull in doing that.I have a problem when user starts moving its finger within that bounds of imagebutton.I am using on ACTION_MOVE to handle this, i am not getting 100% success , sometimes it detects on leave , sometimes not. Please help. Below is code i am using..
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (v.getId()) {
case R.id.btn_audio :
final int action = event.getAction();
// get the View's Rect relative to its parent
v.getHitRect(rect);
// offset the touch coordinates with the values from rect to obtain meaningful coordinates
final float x = event.getX() + rect.left;
final float y = event.getY() + rect.top;
switch (action) {
case MotionEvent.ACTION_DOWN :
audioBtn.setImageDrawable(getResources().getDrawable(R.drawable.img_audio_pressed));
mHandler.sendEmptyMessage(MSG_START_TIMER);
timer.setVisibility(View.VISIBLE);
playBtn.setVisibility(View.GONE);
break;
case MotionEvent.ACTION_MOVE :
Log.e(TAG, rect.top+","+rect.bottom+","+rect.left+","+rect.right);
Log.e(TAG, (int)x+","+(int)y);
if (!rect.contains((int) x, (int) y)) {
Log.e(TAG, "In action move,outside");
audioBtn.setImageDrawable(getResources().getDrawable(R.drawable.img_audio));
playBtn.setVisibility(View.VISIBLE);
if (stop)
mHandler.sendEmptyMessage(MSG_STOP_TIMER);
} else {
Log.e(TAG, "In action move,inside");
audioBtn.setImageDrawable(getResources().getDrawable(R.drawable.img_audio_pressed));
timer.setVisibility(View.VISIBLE);
playBtn.setVisibility(View.GONE);
}
break;
case MotionEvent.ACTION_UP :
// the user raised his finger, cancel the Runnable
audioBtn.setImageDrawable(getResources().getDrawable(R.drawable.img_audio));
playBtn.setVisibility(View.VISIBLE);
if (stop)
mHandler.sendEmptyMessage(MSG_STOP_TIMER);
break;
}
break;

return true
instead of
return false
in your onTouch method

Instead of v.getHitRect(rect); use getLocationInWindow() which returns screen co-ordinates instead of co-ordinates relative to the parent. Update your onTouch code as follows:
//same here
...
...
int[] location = new int[2];
v.getLocationInWindow(location); // get position on the screen.
rect = new Rect(location[0], location[1], location[0]+v.getWidth(), location[1]+v.getHeight());
final float x = event.getX(); // screen x position
final float y = event.getY(); // screen y position
...
...
//same here
