I want to place a ImageView at top left corner when runtime, but it does not work.
This is my layout and code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent"
android:id="#+id/layout_main"
android:layout_height="fill_parent" tools:context=".Main">
</RelativeLayout>
This is code:
RelativeLayout layout = (RelativeLayout)findViewById(R.id.layout_main);
ImageView imageView =new ImageView(getApplicationContext());
imageView.setImageResource(R.drawable.green_apple);
imageView.setScaleX(0.3f);
imageView.setScaleY(0.3f);
imageView.setLeft(0);
imageView.setTop(0);
layout.addView(imageView);
I also tried:
RelativeLayout layout = (RelativeLayout)findViewById(R.id.layout_main);
ImageView imageView =new ImageView(getApplicationContext());
imageView.setImageResource(R.drawable.green_apple);
imageView.setScaleX(0.3f);
imageView.setScaleY(0.3f);
imageView.setX(0);
imageView.setY(0);
layout.addView(imageView);
And:
RelativeLayout layout = (RelativeLayout)findViewById(R.id.layout_main);
ImageView imageView =new ImageView(getApplicationContext());
imageView.setImageResource(R.drawable.green_apple);
imageView.setScaleX(0.3f);
imageView.setScaleY(0.3f);
layout.addView(imageView);
set = new AnimatorSet();
ObjectAnimator aniX = ObjectAnimator.ofFloat(imageView, "x", 0);
aniX.setDuration(100);
ObjectAnimator aniY = ObjectAnimator.ofFloat(imageView, "y", 0);
aniY.setDuration(100);
set.playTogether(aniX, aniY);
set.start()
But same result, this is my result:
Always have large space to Top and Left screen, Although I set 0,0. I also try set height and width of screen, it fly out of screen. I don't know why.
Thank you very much for anyone can explain and how to help me fix it
That is because you use setScaleX and setScaleY, so try the code below:
final ImageView iv = new ImageView(context);
iv.setImageResource(R.drawable.green_apple);
rl.addView(iv);
iv.getViewTreeObserver().addOnPreDrawListener(new OnPreDrawListener() {
#Override
public boolean onPreDraw() {
iv.getViewTreeObserver().removeOnPreDrawListener(this);
int w = (int) (iv.getWidth() * 0.3);
int h = (int) (iv.getHeight() * 0.3);
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(w, h);
iv.setLayoutParams(rlp);
return true;
}
});

Why this isn't working?
for (PlayingCard playingCard : Stack0.Cards)
{
ImageView myImg = new ImageView(this);
myImg.setImageResource(R.drawable.c2);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(new ViewGroup.LayoutParams(CardWidth, ViewGroup.LayoutParams.WRAP_CONTENT));
lp.setMargins(0, 0, 0,0);
//lp.addRule(RelativeLayout.ALIGN_TOP); fails
//lp.addRule(RelativeLayout.ALIGN_PARENT_TOP); fails
//lp.addRule(RelativeLayout.ALIGN_START); fails
lp.addRule(RelativeLayout.ALIGN_PARENT_START);
myImg.setLayoutParams(lp);
mat.addView(myImg);
}
the xml
<RelativeLayout
android:id="#+id/PLAY_Mat"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentStart="true"
>
</RelativeLayout>
The ImageView is successfully being added, but it's centered vertically. I want it to align to top.
I expect this to be the way even without the added rule, as "By default, all child views are drawn at the top-left of the layout" (RelativeLayout documentation).
Try this code:
RelativeLayout rl = new RelativeLayout(this);
for (PlayingCard playingCard : Stack0.Cards)
{
ImageView myImg = new ImageView(this);
myImg.setImageResource(R.drawable.c2);
RelativeLayout.LayoutParams lay = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
lay.setMargins(0, 0, 0,0);
lay.addRule(RelativeLayout.ALIGN_PARENT_TOP);
rl.addView(myImg, lay);
//myImg.setLayoutParams(lp);
//mat.addView(myImg);
}
set MATCH_PARENT to RelativeLayout
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(new ViewGroup.LayoutParams(CardWidth, ViewGroup.LayoutParams.MATCH_PARENT));
or
You can get using getLayoutParams() of RelativeLayout from XML
RelativeLayout.LayoutParams lp = parentRelativeImageview.getLayoutParams();
Solution by OP.
This code works:
for (PlayingCard playingCard : Stack0.Cards)
{
ImageView myImg = new ImageView(this);
myImg.setImageResource(R.drawable.a1);
RelativeLayout.LayoutParams lay = new RelativeLayout.LayoutParams(CardWidth, CardHeight);
lay.setMargins(playingCard.UI_MarginLeft, playingCard.UI_MarginTop, 0, 0);
mat.addView(myImg, lay);
}
The key here is CardWidth and CardHeight are both set, and both correct. By correct, I mean correct ratios. Want to double the width? Then double the height etc. If one of w or h is a pixel int, and the other WRAP_CONTENT, then weirdness happens (in the form of the image having either a top margin or a left margin).
Once both w and h are set correctly, lp.addRule(RelativeLayout.ALIGN_PARENT_START) isn't needed.
Here is the Android Studio code for my android app:
FrameLayout root = (FrameLayout) findViewById(R.id.root);
ImageView img = new ImageView(this);
img.setBackgroundColor(Color.RED);
//..load something inside the ImageView, we just set the background color
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(20, 20);
params.leftMargin=Math.round(deltaX);
params.topMargin=Math.round(deltaY);
root.addView(img,params);
//...
I want to move this with animation when the value of topMargin and leftMargin change.
You can change to Padding
FrameLayout root = (FrameLayout) findViewById(R.id.root);
ImageView img = new ImageView(this);
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(20, 20);
img.setLayoutParams(params);
img.setBackgroundColor(Color.RED);
//..load something inside the ImageView, we just set the background color
root.setPadding(deltaX, deltaX, 0, 0);
root.addView(img);
Then, you can use Property Animation
ObjectAnimator.ofFloat(root, "translationX", 0, 1000).start();
ObjectAnimator.ofFloat(root, "translationY", 0, 1000).start();
or
root.animate().translationY(100);
Is it possible to set the absolute position of a view in Android? (I know that there is an AbsoluteLayout, but it's deprecated...)
For example, if I have a 240x320px screen, how could I add an ImageView which is 20x20px such that its center is at the position (100,100)?
You can use RelativeLayout. Let's say you wanted a 30x40 ImageView at position (50,60) inside your layout. Somewhere in your activity:
// Some existing RelativeLayout from your layout xml
RelativeLayout rl = (RelativeLayout) findViewById(R.id.my_relative_layout);
ImageView iv = new ImageView(this);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);
More examples:
Places two 30x40 ImageViews (one yellow, one red) at (50,60) and (80,90), respectively:
RelativeLayout rl = (RelativeLayout) findViewById(R.id.my_relative_layout);
ImageView iv;
RelativeLayout.LayoutParams params;
iv = new ImageView(this);
iv.setBackgroundColor(Color.YELLOW);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);
iv = new ImageView(this);
iv.setBackgroundColor(Color.RED);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 80;
params.topMargin = 90;
rl.addView(iv, params);
Places one 30x40 yellow ImageView at (50,60) and another 30x40 red ImageView <80,90> relative to the yellow ImageView:
RelativeLayout rl = (RelativeLayout) findViewById(R.id.my_relative_layout);
ImageView iv;
RelativeLayout.LayoutParams params;
int yellow_iv_id = 123; // Some arbitrary ID value.
iv = new ImageView(this);
iv.setId(yellow_iv_id);
iv.setBackgroundColor(Color.YELLOW);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);
iv = new ImageView(this);
iv.setBackgroundColor(Color.RED);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 80;
params.topMargin = 90;
// This line defines how params.leftMargin and params.topMargin are interpreted.
// In this case, "<80,90>" means <80,90> to the right of the yellow ImageView.
params.addRule(RelativeLayout.RIGHT_OF, yellow_iv_id);
rl.addView(iv, params);
In general, you can add a View in a specific position using a FrameLayout as container by specifying the leftMargin and topMargin attributes.
The following example will place a 20x20px ImageView at position (100,200) using a FrameLayout as fullscreen container:
XML
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/root"
android:background="#33AAFF"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
Activity / Fragment / Custom view
//...
FrameLayout root = (FrameLayout)findViewById(R.id.root);
ImageView img = new ImageView(this);
img.setBackgroundColor(Color.RED);
//..load something inside the ImageView, we just set the background color
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(20, 20);
params.leftMargin = 100;
params.topMargin = 200;
root.addView(img, params);
//...
This will do the trick because margins can be used as absolute (X,Y) coordinates without a RelativeLayout:
Just to add to Andy Zhang's answer above, if you want to, you can give param to rl.addView, then make changes to it later, so:
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);
Could equally well be written as:
params = new RelativeLayout.LayoutParams(30, 40);
rl.addView(iv, params);
params.leftMargin = 50;
params.topMargin = 60;
So if you retain the params variable, you can change the layout of iv at any time after adding it to rl.
A more cleaner and dynamic way without hardcoding any pixel values in the code.
I wanted to position a dialog (which I inflate on the fly) exactly below a clicked button.
and solved it this way :
// get the yoffset of the position where your View has to be placed
final int yoffset = < calculate the position of the view >
// position using top margin
if(myView.getLayoutParams() instanceof MarginLayoutParams) {
((MarginLayoutParams) myView.getLayoutParams()).topMargin = yOffset;
}
However you have to make sure the parent layout of myView is an instance of RelativeLayout.
more complete code :
// identify the button
final Button clickedButton = <... code to find the button here ...>
// inflate the dialog - the following style preserves xml layout params
final View floatingDialog =
this.getLayoutInflater().inflate(R.layout.floating_dialog,
this.floatingDialogContainer, false);
this.floatingDialogContainer.addView(floatingDialog);
// get the buttons position
final int[] buttonPos = new int[2];
clickedButton.getLocationOnScreen(buttonPos);
final int yOffset = buttonPos[1] + clickedButton.getHeight();
// position using top margin
if(floatingDialog.getLayoutParams() instanceof MarginLayoutParams) {
((MarginLayoutParams) floatingDialog.getLayoutParams()).topMargin = yOffset;
}
This way you can still expect the target view to adjust to any layout parameters set using layout XML files, instead of hardcoding those pixels/dps in your Java code.
Just in case it may help somebody, you may also try this animator ViewPropertyAnimator as below
myView.animate().x(50f).y(100f);
myView.animate().translateX(pixelInScreen)
Note: This pixel is not relative to the view. This pixel is the pixel
position in the screen.

My code for Xamarin,
I am using FrameLayout for this purpose and following is my code:
List<object> content = new List<object>();
object aWebView = new {ContentType="web",Width="300", Height = "300",X="10",Y="30",ContentUrl="http://www.google.com" };
content.Add(aWebView);
object aWebView2 = new { ContentType = "image", Width = "300", Height = "300", X = "20", Y = "40", ContentUrl = "https://www.nasa.gov/sites/default/files/styles/image_card_4x3_ratio/public/thumbnails/image/leisa_christmas_false_color.png?itok=Jxf0IlS4" };
content.Add(aWebView2);
FrameLayout myLayout = (FrameLayout)FindViewById(Resource.Id.frameLayout1);
foreach (object item in content)
{
string contentType = item.GetType().GetProperty("ContentType").GetValue(item, null).ToString();
FrameLayout.LayoutParams param = new FrameLayout.LayoutParams(Convert.ToInt32(item.GetType().GetProperty("Width").GetValue(item, null).ToString()), Convert.ToInt32(item.GetType().GetProperty("Height").GetValue(item, null).ToString()));
param.LeftMargin = Convert.ToInt32(item.GetType().GetProperty("X").GetValue(item, null).ToString());
param.TopMargin = Convert.ToInt32(item.GetType().GetProperty("Y").GetValue(item, null).ToString());
switch (contentType) {
case "web":{
WebView webview = new WebView(this);
//webview.hei;
myLayout.AddView(webview, param);
webview.SetWebViewClient(new WebViewClient());
webview.LoadUrl(item.GetType().GetProperty("ContentUrl").GetValue(item, null).ToString());
break;
}
case "image":
{
ImageView imageview = new ImageView(this);
//webview.hei;
myLayout.AddView(imageview, param);
var imageBitmap = GetImageBitmapFromUrl("https://www.nasa.gov/sites/default/files/styles/image_card_4x3_ratio/public/thumbnails/image/leisa_christmas_false_color.png?itok=Jxf0IlS4");
imageview.SetImageBitmap(imageBitmap);
break;
}
}
}
It was useful for me because I needed the property of view to overlap each other on basis of their appearance, e.g the views get stacked one above other.
I want to place ImageButton at x, y location of my view.
The problem is that Android adds padding around image.
Because I don't know exact size of padding, I cannot place image button at exact location.
So, I want to remove padding.
How can I remove padding around image programmatically?
button.setPadding(0, 0, 0, 0) makes button width shorter and height longer than bitmap.
button.getLayoutParams().width gives minus value.
What I tried so far is like this.
protected class MyLayout extends RelativeLayout {
Bitmap img;
ImageButton button;
public MyLayout(Context context) {
button = new ImageButton(context);
img = BitmapFactory.decodeResource(getResources(), R.drawable.img);
button.setImageBitmap(img);
params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
button.setLayoutParams(params);
params.setMargins(x, y, 0, 0);
button.setBackgroundDrawable(null);
addView(button, params);
}
}
EDIT
Use this...
MarginLayoutParams marginParams = new MarginLayoutParams(image.getLayoutParams());
int left = someValue;
int top = someValue;
marginParams.setMargins(left, top, 0, 0);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(marginParams);
image.setLayoutParams(layoutParams);
Is it possible to set the absolute position of a view in Android? (I know that there is an AbsoluteLayout, but it's deprecated...)
For example, if I have a 240x320px screen, how could I add an ImageView which is 20x20px such that its center is at the position (100,100)?
