Guys I have a cardview and I want to add 2 button on it with rule but addRule() method is not working. In the picture, figure A is occurring but I want to make figure B, I mean, I want the buttons set align_parent_right and align_parent_bottom and the second button adjacent to first one. When I run it, figure A occuring. Any suggestions?
RelativeLayout.LayoutParams rl= (RelativeLayout.LayoutParams) iView.getLayoutParams();
RelativeLayout.LayoutParams lparams = new RelativeLayout.LayoutParams(width/4,height/5);
RelativeLayout.LayoutParams lparams2 = new RelativeLayout.LayoutParams(width/4,height/5);
removeButton=new Button(mContext);
modifyButton=new Button(mContext);
lparams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
lparams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
cardView.setLayoutParams(rl);
cardView.addView(removeButton,lparams);
cardView.addView(modifyButton,lparams2);
Try this:-
RelativeLayout mainLayout = (RelativeLayout) findViewById(R.id.mainLayout);
CardView cardView = new CardView(this);
ViewGroup.LayoutParams cardParams = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
cardView.setLayoutParams(cardParams);
mainLayout.addView(cardView);
RelativeLayout relativeLayout = new RelativeLayout(this);
ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
relativeLayout.setLayoutParams(layoutParams);
cardView.addView(relativeLayout);
LinearLayout linearLayout = new LinearLayout(this);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
linearLayout.setLayoutParams(params);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
linearLayout.setGravity(Gravity.RIGHT);
relativeLayout.addView(linearLayout);
Button removeButton = new Button(this);
Button modifyButton = new Button(this);
removeButton.setText("Remove");
modifyButton.setText("Modify");
linearLayout.addView(removeButton);
linearLayout.addView(modifyButton);

Here's my Code
mainView = new MainView(this, imageId, text, 3);
mainView.setOnTouchListener(this);
LinearLayout.LayoutParams mainParams = new
LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
LinearLayout mainLinear = new LinearLayout(this);
ScrollView.LayoutParams scrollParams = new
ScrollView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
ScrollView scrollView = new ScrollView(this);
LinearLayout.LayoutParams myViewParams = new
LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
mainLinear.addView(mainView, myViewParams);
scrollView.addView(mainLinear, mainParams);
addContentView(scrollView, scrollParams);
Of course it works within LinearLayout only. Please tell me how to put it inside a ScrollView.
ScrollView's child should only have height as WRAP_CONTENT. If you try the same layout using xml AS will give you a lint warning saying exactly this.
If you need your child view to occupy full height of scroll view when content is less you could use setFillViewport().
This should work for you:
mainView = new MainView(this, imageId, text, 3);
mainView.setOnTouchListener(this);
LinearLayout.LayoutParams mainParams = new
LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
LinearLayout mainLinear = new LinearLayout(this);
ScrollView.LayoutParams scrollParams = new
ScrollView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
ScrollView scrollView = new ScrollView(this);
LinearLayout.LayoutParams myViewParams = new
LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
mainLinear.addView(mainView, myViewParams);
scrollView.addView(mainLinear, mainParams);
scrollView.setFillViewport(true);
addContentView(scrollView, scrollParams);
I need to be able to add a layout to my main layout from xml file many times programatically.
The problem is handling assigning ids of the new layout's views. See the code:
MainFragment.java
private int belowOfWhat = R.id.layout_header;
...
onActivityResult:
LayoutInflater myInflater = LayoutInflater.from(getContext());
RelativeLayout layout = (RelativeLayout) myInflater.inflate(R.layout.assignment_layout, null, false);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT);
//here problems start
//i want to position the new layout below the previously created layout
params.addRule(RelativeLayout.BELOW, belowOfWhat);
layout.setLayoutParams(params);
mRelativeLayout = rootView.findViewById(R.id.to_do_layout);
mRelativeLayout.addView(layout);
belowOfWhat = generateViewId();
idsOfToDos.add(belowOfWhat);
CheckBox assignmentCheckbox = (CheckBox)
//assignment_checkbox is an id of checkbox in the xml layout I add
rootView.findViewById(R.id.assignment_checkbox);
assignmentCheckbox.setId(belowOfWhat);
assignmentCheckbox.setText(mToDoInfo);
I don't know where the problem is, so here is how the app works now: I add a new layout, it gets positioned correctly below layout_header.
But when I add the second or more layouts they overlap each other on top of the app instead of being positioned one below the other.
I'd appreciate if you guided me to the solution of the problem.
If you don't need views'ids for other purposes you could solve more simple.
If I've understood what you are trying to do, what you need is a vertical LinearyLayout instead of a RelativeLayout, then subviews will be added one below each other
You have to use Relative Layout and use the following properties with that to align the views.
RelativeLayout.BELOW
RelativeLayout.RIGHT_OF
RelativeLayout.ALIGN_BOTTOM
RelativeLayout layout = new RelativeLayout(this);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
layout.setLayoutParams(layoutParams);
RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params3 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params4 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
TextView tv1 = new TextView(this);
tv1.setId(1);
tv1.setText("textView1");
TextView tv2 = new TextView(this);
params2.addRule(RelativeLayout.RIGHT_OF, tv1.getId());
tv2.setId(2);
tv2.setText("textView2");
TextView tv3 = new TextView(this);
params3.addRule(RelativeLayout.BELOW, tv1.getId());
tv3.setId(3);
tv3.setText("textView3");
TextView tv4 = new TextView(this);
params4.addRule(RelativeLayout.RIGHT_OF, tv3.getId());
params4.addRule(RelativeLayout.ALIGN_BOTTOM, tv3.getId());
tv4.setId(4);
tv4.setText("textView4");
layout.addView(tv1, params1);
layout.addView(tv2, params2);
layout.addView(tv3, params3);
layout.addView(tv4, params4);
hope so it gives you an idea how to align views pragmatically.
I am working on dynamic UI. I have Parent LinearLayout and I created another LinearLayout in it and add TextView in this LinearLayout. I want to Right Align of Screen that TextView
I tried like below
public MessageView(LinearLayout parent, Message msg) {
myParent = parent;
messageDetails = new LinearLayout(parent.getContext());
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT);
layoutParams.gravity = RelativeLayout.ALIGN_PARENT_RIGHT;
messageDetails.setLayoutParams(layoutParams);
senderTV = new TextView(parent.getContext());
senderTV.setTypeface(null, Typeface.ITALIC);
messageDetails.addView(senderTV);
}
How can I do it?
Try this:
messageDetails = new RelativeLayout(parent.getContext());
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
rlp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
messageDetails.addView(senderTV);
I want to add a linerlayout at the bottom of relativelayout. How could I achieve that?
This is the code snippet that I am using:
rl=new RelativeLayout(this);
ll = new LinearLayout(this);
buttons=new LinearLayout(this);
buttons.setOrientation(LinearLayout.HORIZONTAL);
ll.setOrientation(LinearLayout.VERTICAL);
//buttons.addRule();
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
params.topMargin=450;
//params.gravity = Gravity.BOTTOM;
rl.addView(ll);
rl.addView(buttons,params);
I think something like this, should work :
rl=new RelativeLayout(this);
buttons=new LinearLayout(this);
buttons.setOrientation(LinearLayout.HORIZONTAL);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
rl.addView(buttons, lp);
I have a program that generates a rows of 4 buttons, in a horizontal container that gets added to a vertical container.
I cannot figure out how to have it so the buttons are centered, now they are aligns to the right hand side. Code:
for(int i=0; i<cGlobals.mNames.length; i+=2) {
iSoundIdList[i]=soundPool.load(this, cGlobals.mSounds[i], 1);
iSoundIdList[i+1]=soundPool.load(this, cGlobals.mSounds[i+1], 1);
// would like these views to all be centered
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
layout.setLayoutParams(llp);
favBut[i]=new ImageView(this);
favBut[i].setImageResource(R.drawable.heartunselected);
favBut[i].setId(defStartFavId+i);
favBut[i].setOnClickListener(this);
layout.addView(favBut[i]);
Button but1=new Button(this);
but1.setText( cGlobals.mNames[i]);
but1.setWidth(120);
layout.addView(but1);
but1.setOnClickListener(this);
but1.setId(defStartButId+i);
TextView t=new TextView(this);
t.setText(" ");
layout.addView(t);
favBut[i+1]=new ImageView(this);
favBut[i+1].setImageResource(R.drawable.heartunselected);
favBut[i+1].setId(defStartFavId+i+1);
favBut[i+1].setOnClickListener(this);
layout.addView(favBut[i+1]);
t=new TextView(this);
t.setText(" ");
layout.addView(t);
Button but2=new Button(this);
but2.setText( cGlobals.mNames[i+1]);
but2.setWidth(120);
but2.setId(defStartButId+i+1);
but2.setOnClickListener(this);
layout.addView(but2);
Container.addView(layout);
}
Below snippet will help
RelativeLayout relativeLayout = new RelativeLayout(this);
relativeLayout.setLayoutParams(new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT));
ImageView imageView = new ImageView(this);
imageView.setImageResource(getResources().getIdentifier(
"sample_image", "drawable", getPackageName()));
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.CENTER_IN_PARENT);
imageView.setLayoutParams(lp);
relativeLayout.addView(imageView);
