How to add more than one relative layout to the linear layout programmatically .
I tried but it gives me this exception "Specified child already has a parent. You must call removeview()"
Here is my code,
RelativeLayout addlangmid = new RelativeLayout(mActivity);
addlangmid.setBackgroundResource(R.drawable.language_bg_top);
TextView langname = new TextView(mActivity);
LayoutParams params = new LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(20, 0, 30, 30);
langname.setText(str[0]);
addlangmid.addView(langname, params);
fulllay.addView(addlangmid, 0);
RelativeLayout addlangmid1 = new RelativeLayout(mActivity);
addlangmid.setBackgroundResource(R.drawable.language_bg_middle);
TextView langname1 = new TextView(mActivity);
LayoutParams params1 = new LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
params1.setMargins(20, 0, 30, 30);
langname1.setText(str[0]);
addlangmid1.addView(langname, params1);
fulllay.addView(addlangmid1, 1);
Change the below line
addlangmid1.addView(langname, params1);
to
addlangmid1.addView(langname1, params1);
You are adding langname to addlangmid and addlangmid1. Hence the error is coming.

I am making a layout programmatically, in which on a click of button, a new relative layout is added in a grid layout. All my code is working fine, but the problem is that i am unable to set margins to the relative layout inside the grid layout. Please help!!
Thanks
You should use RelativeLayout.LayoutParams instead of LinearLayout.LayoutParams.
Try this:
RelativeLayout.LayoutParams relativeParams =new RelativeLayout.LayoutParams(300, 300);
relativeParams.setMargins(16, 16, 16, 16);
rlLocation.setLayoutParams(relativeParams);
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 having some troubles creating a relativeLayout programmatically.For better understanding I attached a picture below. The things with plus and minus are buttons, which should also be dynamically created and added to the layout. The values of tv4 and tv5 should increase/decrease accordingly to button presses.
What I have done so far:
1) creating the layout:
RelativeLayout rl = new RelativeLayout(this);
rl.setId(i);
rl.setBackgroundResource(R.drawable.bg);
RelativeLayout.LayoutParams Lparams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
Lparams.addRule(RelativeLayout.BELOW, R.id.RL_default);
Lparams.setMargins(3, 5, 3, 0);
rl.setLayoutParams(Lparams);
2) adding the tv1:
Lparams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
Lparams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
Lparams.setMargins(10, 0, 0, 0);
TextView txt = new TextView(this);
txt.setTextColor(Color.parseColor("#FFFFFF"));
txt.setId(x);
txt.setTextSize(25);
txt.setLayoutParams(Lparams);
txt.setText(name);
rl.addView(txt);
3) adding the tv2:
Lparams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
Lparams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
Lparams.addRule(RelativeLayout.BELOW, txt.getId());
Lparams.setMargins(10, 0, 0, 0);
TextView txtS = new TextView(this);
txtS.setId(y);
txtS.setText("Test: ");
txtS.setTextSize(22);
txtS.setLayoutParams(Lparams);
txtS.setGravity(Gravity.BOTTOM);
txtS.setPadding(0, 0, 0, 20);
rl.addView(txtS);
4) now I want to create the first button:
Button btnSminus = new Button(this);
btnSminus.setId(btn1);
btnSminus.setText("<");
btnSminus.setTextSize(20);
Lparams= new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
Lparams.addRule(RelativeLayout.RIGHT_OF, txtS.getId());
btnSminus.setLayoutParams(Lparams);
rl.addView(btnSminus);
The problem is, the the button View seems to just disappear from the screen when the line Lparams.addRule(RelativeLayout.RIGHT_OF, txtS.getId()); is executed. What can be the reason?
My guess would be that it's because you set the width of txtS to match_parent, so the button gets pushed off the screen. You can fix that by changing that to wrap_content.
How to set margin in relative layout with code (not XML)?
I use this code but nothing happened:
RelativeLayout rlDetail = new RelativeLayout(context);
rlDetail.setBackgroundResource(R.drawable.bg_round);
RelativeLayout.LayoutParams rlDetailParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
rlDetailParams.setMargins(35, 10, 35, 0);
rlDetail.setLayoutParams(rlDetailParams);
try this answer set the absolute position of a view in Android
as mentioned in the link above you should use
TextView tv1 = new TextView(context);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = needed_margin;
params.topMargin = needed_margin;
// add your textview like this
rl.addView(tv1, params);
In an Android activity....how do I do the following using just code instead of XML?
<TextView android:background="#0000ff" android:layout_margin="2dip"/>
I also need text align right...
stuck on it for a while =( if someone could help
thanks
UPDATE
I tried the code below
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT);
//250);
lp.setMargins(5,5,5,5);
and i did
row.addView(t1, lp);
row.addView(t2);
row.addView(t3);
row.addView(t4);
I also tried LinearLayout
but t1 for some reason doesn't show at all anymore....
here is how to code a textView:
mTextView = new TextView(this);
mTextView.setGravity(Gravity.CENTER_VERTICAL);
mTextView.setText(R.string.instructions);
mTextView.setTextColor(0xFF000000);
mTextView.setPadding(20, 8, 8, 20);
mTextView.setTextSize(TypedValue.COMPLEX_UNIT_PT, 8);
mScroll = new ScrollView(this);
mScroll.setScrollbarFadingEnabled(false);
mTextPane = new RelativeLayout(this);
mTextPane.setVisibility(View.GONE);
//mScroll.setVisibility(View.GONE);
mScroll.addView(mTextView);
mTextPane.addView(mScroll);
Resources res = getResources();
//Drawable drawable = res.getDrawable(R.drawable.text_pane_feather2);
Drawable drawable = res.getDrawable(R.drawable.text);
mTextPane.setBackgroundDrawable(drawable);
//RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams( 420, 420 );
RelativeLayout.LayoutParams lp =
new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.WRAP_CONTENT,
//RelativeLayout.LayoutParams.WRAP_CONTENT);
250);
lp.setMargins(0,0,0,30);
lp.addRule(RelativeLayout.CENTER_HORIZONTAL );
lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
layout.addView(mTextPane, lp);
Try the TextViews setBackgroundColour() method.
For setting the layout params, use the setMargins(int,int,int,int) from the MarginLayoutParams class.
See the documentation for more details at:
View.setBackgroundColour and
Layout Params
