I am trying to set margin from top.
RelativeLayout root = (RelativeLayout) view.findViewById(R.id.root);
listview = new PullListView(getActivity());
root.addView(listview);
How can I set margin of listview?
RelativeLayout.LayoutParams relativeParams =(RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
relativeParams.setMargins(0, 80, 0, 0); // left, top, right, bottom
relativeLayout.setLayoutParams(relativeParams);
Use LayoutParams
LayoutParams params=(LayoutParams) root.getLayoutParams();
params.leftMargin=0;
params.rightMargin=0;
params.rightMargin=0;
params.leftMargin=0;
root.setLayoutParams(params);

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.
How can I programatically add a RelativeLayout that is aligned to the bottom of parent, and add a margin or padding in the same RelativeLayout?
Example:
Here's how you can do that:
// Get the parent layout
RelativeLayout parent = (RelativeLayout) findViewById(R.id.parent);
// Create your custom layout
RelativeLayout relativeLayout = new RelativeLayout(this);
// Create LayoutParams for it // Note 200 200 is width, height in pixels
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(200, 200);
// Align bottom-right, and add bottom-margin
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
params.bottomMargin = 100;
relativeLayout.setLayoutParams(params);
relativeLayout.setBackgroundColor(Color.BLUE);
// Add the custom layout to your parent layout
parent.addView(relativeLayout);
you can try this it work in my case:
RelativeLayout.LayoutParams rlp = (RelativeLayout.LayoutParams) view.getLayoutParams();
// position on right bottom
rlp.addRule(RelativeLayout.ALIGN_PARENT_LEFT, 0);
rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP,0);
rlp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
rlp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
I'm trying to add programmatically a margin top to my RelativeLayout in my activity. Using the xml I can do it in this mode: android:layout_marginTop="10dp", but when I'm trying to do it programmatically nothing changes... As you can see I'm using some RelativeLayout (there is a for loop) in one LinearLayout container.
This is the code that I'm using:
//LINEAR LAYOUT
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
linearLayout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
for (int i=1; i<=3; i++){
//RELATIVE LAYOUT
RelativeLayout relativeLayout = new RelativeLayout(this);
relativeLayout.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT));
relativeLayout.setBackgroundColor(getResources().getColor(R.color.grayColor));
//CODE FOR ADD MARGINS
RelativeLayout.LayoutParams relativeParams = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
relativeParams.topMargin=80;
relativeLayout.setLayoutParams(relativeParams);
//IMAGE VIEW
ImageView selectedPhoto = new ImageView(this);
selectedPhoto.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT));
selectedPhoto.setImageResource(R.drawable.ic_launcher);
//TEXT VIEWS
TextView numberCopies = new TextView(this);
numberCopies.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT));
numberCopies.setGravity(Gravity.CENTER);
numberCopies.setPadding(25, 25, 25, 25);
numberCopies.setTextColor(getResources().getColor(R.color.blackColor));
numberCopies.setText("2 copies ");
RelativeLayout.LayoutParams layoutParamsNumberCopies = (RelativeLayout.LayoutParams) numberCopies.getLayoutParams();
layoutParamsNumberCopies.addRule(RelativeLayout.CENTER_HORIZONTAL);
numberCopies.setLayoutParams(layoutParamsNumberCopies);
TextView priceCopies = new TextView(this);
priceCopies.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT));
priceCopies.setGravity(Gravity.CENTER);
numberCopies.setPadding(25, 25, 25, 25);
priceCopies.setTextColor(getResources().getColor(R.color.redColor));
priceCopies.setText("$ 25 ");
RelativeLayout.LayoutParams layoutParamsPriceCopies = (RelativeLayout.LayoutParams) priceCopies.getLayoutParams();
layoutParamsPriceCopies.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
priceCopies.setLayoutParams(layoutParamsPriceCopies);
relativeLayout.addView(selectedPhoto);
relativeLayout.addView(numberCopies);
relativeLayout.addView(priceCopies);
linearLayout.addView(relativeLayout);
}
scrollView.addView(linearLayout);
setContentView(scrollView);
I think that the failing block code is this:
//CODE FOR ADD MARGINS
RelativeLayout.LayoutParams relativeParams = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
relativeParams.topMargin=80;
relativeLayout.setLayoutParams(relativeParams);
Got solution.
When you are using RelativeLayout inside LinearLayout, you need to use LinearLayout.LayoutParams instead of RelativeLayout.LayoutParams.
So replace your following code...
RelativeLayout.LayoutParams relativeParams = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
relativeParams.setMargins(0, 80, 0, 0); // left, top, right, bottom
relativeLayout.setLayoutParams(relativeParams);
with...
// CODE FOR ADD MARGINS
LinearLayout.LayoutParams linearParams = new LinearLayout.LayoutParams(
new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
linearParams.setMargins(0, 80, 0, 0);
relativeLayout.setLayoutParams(linearParams);
relativeLayout.requestLayout();
You can use setMargins (int left, int top, int right, int bottom).
Try like this..
//CODE FOR ADD MARGINS
RelativeLayout.LayoutParams relativeParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
relativeParams.setMargins(0, 80, 0, 0);
relativeLayout.setLayoutParams(relativeParams);
Layout params should be set with resp to parentLayout .. in this case its LinearLayout as rightly pointed by #ChintanRathod, so
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
will do the trick..
Be aware that you are using a relative layout inside a linear layout so you should use LinearLayout.LayoutParams
I would replace this :
//RELATIVE LAYOUT
RelativeLayout relativeLayout = new RelativeLayout(this);
relativeLayout.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT));
relativeLayout.setBackgroundColor(getResources().getColor(R.color.grayColor));
//CODE FOR ADD MARGINS
RelativeLayout.LayoutParams relativeParams = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
relativeParams.topMargin=80;
relativeLayout.setLayoutParams(relativeParams);
by this :
//RELATIVE LAYOUT WITH PROPER LAYOUT PARAMS TO ADD MARGINS
RelativeLayout relativeLayout = new RelativeLayout(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(0, 80, 0, 0);
relativeLayout.setLayoutParams(params);
relativeLayout.setBackgroundColor(getResources().getColor(R.color.grayColor));
Note also that you should use WRAP_CONTENT as height configuration for children in a vertical linearLayout. ( in FILL_PARENT or MATCH_PARENT mode it will fill the parent without leaving space for the other children)
// kotlin
val relativeParams = relativeLayoutGeneral.layoutParams as FrameLayout.LayoutParams
relativeParams.setMargins(0, 7, 0, 111)
relativeLayoutGeneral.layoutParams = relativeParams
I'm trying to add pragmatically a margin top to my Relative Layout in my activity.
Using the xml i can do it in this mode: android:layout_marginTop="10dp", but when i'm trying to do it pragmatically nothing change...
This is the code that i'm using:
//SCROLL VIEW
ScrollView scrollView = new ScrollView(this);
scrollView.setBackground(getResources().getDrawable(R.drawable.background));
scrollView.setLayoutParams(new ScrollView.LayoutParams(ScrollView.LayoutParams.MATCH_PARENT,
ScrollView.LayoutParams.MATCH_PARENT));
scrollView.setPadding(20, 20, 20, 20);
//LINEAR LAYOUT
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
linearLayout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
for (int i=1; i<=3; i++){
//RELATIVE LAYOUT
RelativeLayout relativeLayout = new RelativeLayout(this);
relativeLayout.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT));
relativeLayout.setBackgroundColor(getResources().getColor(R.color.grayColor));
RelativeLayout.LayoutParams head_params = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
head_params.setMargins(0, 80, 0, 0);
relativeLayout.setLayoutParams(head_params);
//Need to understand how put a margin top to the relativeLayout
//IMAGE VIEW
ImageView selectedPhoto = new ImageView(this);
selectedPhoto.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT));
selectedPhoto.setImageResource(R.drawable.ic_launcher);
//TEXT VIEWS
TextView numberCopies = new TextView(this);
numberCopies.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT));
numberCopies.setGravity(Gravity.CENTER);
numberCopies.setPadding(25, 25, 25, 25);
numberCopies.setTextColor(getResources().getColor(R.color.blackColor));
numberCopies.setText("2 copies ");
RelativeLayout.LayoutParams layoutParamsNumberCopies = (RelativeLayout.LayoutParams) numberCopies.getLayoutParams();
layoutParamsNumberCopies.addRule(RelativeLayout.CENTER_HORIZONTAL);
numberCopies.setLayoutParams(layoutParamsNumberCopies);
TextView priceCopies = new TextView(this);
priceCopies.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT));
priceCopies.setGravity(Gravity.CENTER);
numberCopies.setPadding(25, 25, 25, 25);
priceCopies.setTextColor(getResources().getColor(R.color.redColor));
priceCopies.setText("$ 25 ");
RelativeLayout.LayoutParams layoutParamsPriceCopies = (RelativeLayout.LayoutParams) priceCopies.getLayoutParams();
layoutParamsPriceCopies.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
priceCopies.setLayoutParams(layoutParamsPriceCopies);
relativeLayout.addView(selectedPhoto);
relativeLayout.addView(numberCopies);
relativeLayout.addView(priceCopies);
linearLayout.addView(relativeLayout);
}
scrollView.addView(linearLayout);
setContentView(scrollView);
}
I have tried also relativeLayout.setMargins(20, 0, 0, 0); but seems that this method isn't available for relativeLayout. I'm not sure about it.
Thanks
Change your setmargins line to
head_params.setMargins(0, 80, 0, 0);
Margin parameters go clockwise starting with the left margin, i.e. (left, top, right, bottom). However, if you have other margins other than the top one, this will delete them. A much easier and more intuitive way is to simply write
header_params.topMargin=80;
Also not to forget, you never set your header_params back to your view. Add this line below:
relativeLayout.setLayourParams(header_params);
Try this
RelativeLayout.LayoutParams head_params = (RelativeLayout.LayoutParams)headView.getLayoutParams();
head_params.setMargins(0, 80, 0, 0);//substitute parameters for left, top, right, bottom
If I use xml file I have a option called layout_margin (for example layout_margin ="1dp" for text view ) but I want to set programmatically and I dont know how to do it.
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)textview.getLayoutParams();
params.setMargins(20, 0, 0, 0);
textview.setLayoutParams(params);
Please Google before adding your question to StackOverflow.
TextView tv = (TextView)findViewById(R.id.my_text_view);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)tv.getLayoutParams();
params.setMargins(0, 0, 10, 0); //substitute parameters for left, top, right, bottom
tv.setLayoutParams(params);
Note, that not all LayoutParams has method setMargins();
RelativeLayout, LinearLayout etc has their own inner class LayoutParams, so availability of setMargins is not always available.
You can do by this:
TextView text = (TextView) findViewById(R.id.text);
LinearLayout.LayoutParams params= new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.setMargins(left, top, right, bottom);//pass int values for left,top,right,bottom
text.setLayoutParams(params);
TextView tv = (TextView) findViewById(R.id.tvId);
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
llp.setMargins(50, 0, 0, 0); // llp.setMargins(left, top, right, bottom);
tv.setLayoutParams(llp);
Try This: It worked...
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT
);
params.setMargins(0, 10, 0, 0);
firstName.setLayoutParams(params);
You can use the setMargins() on the LinearLayout.LayoutParams. See the answer of this StackOverflow question for more information.
TextView tv = (TextView)findViewById(R.id.item_title));
RelativeLayout.LayoutParams mRelativelp = (RelativeLayout.LayoutParams) tv
.getLayoutParams();
mRelativelp.setMargins(DptoPxConvertion(15), 0, DptoPxConvertion (15), 0);
tv.setLayoutParams(mRelativelp);
private int DptoPxConvertion(int dpValue)
{
return (int)((dpValue * mContext.getResources().getDisplayMetrics().density) + 0.5);
}
getLayoutParams() of textview should be casted to the corresponding Params based on the Parent of the textview in xml.
<RelativeLayout>
<TextView
android:id="#+id/item_title">
</RelativeLayout>
If parent of the TextView is RelativeLayout means, then RelativeLayout.LayoutParams as above. If parent is LinearLayout means then
LinearLayout.LayoutParams mLinearlp = (LinearLayout.LayoutParams) tv
.getLayoutParams();
To render the same real size on different devices use DptoPxConvertion() method which I have used above. setMargin(left,top,right,bottom) params will take values in pixel not in dp.
