I have an Achievement dialog, and would like this:
And this is my code, each achievement is a relative layout, and all are contained in a LinearLayout (pnlAchievement):
RelativeLayout pnlItem = new RelativeLayout(Parent);
pnlItem.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView txtItemName = new TextView(Parent);
txtItemName.setText(ACHIEVEMENTS_NAME[i]);
txtItemName.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
TextView txtAchived = new TextView(Parent);
txtAchived.setText(Achived[i] ? "Achieved!" : "Not Achieved!");
RelativeLayout.LayoutParams rlpAchived = new RelativeLayout.LayoutParams(
new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
rlpAchived.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
rlpAchived.addRule(RelativeLayout.ALIGN_RIGHT, txtItemName.getId());
txtAchived.setLayoutParams(rlpAchived);
TextView txtDescription = new TextView(Parent);
txtDescription.setText(ACHIEVEMENTS_DESCRIPTION[i]);
txtDescription.setHorizontallyScrolling(false);
RelativeLayout.LayoutParams rlpDesc = new RelativeLayout.LayoutParams(
new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
rlpDesc.addRule(RelativeLayout.ALIGN_BOTTOM, txtItemName.getId());
rlpDesc.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
txtDescription.setLayoutParams(rlpDesc);
pnlItem.addView(txtItemName);
pnlItem.addView(txtAchived);
pnlItem.addView(txtDescription);
pnlAchievement.addView(pnlItem);
It work well list all the achievements, but the description is NOT below the Name, it is OVER the Name, like this:
And, can you please tell me how to add the line between every item without using Canvas (this is not very important, but if there is, it's better)?
You need to use RelativeLayout.BELOW
For the line you can use a Label with a backgroundcolor.

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.
Every time I set the layout param of TextView to wrap content or fill parent it's not showing in the view, but when I set it to pixels it's working why is that?
Here is the relevant code:
items = (LinearLayout) findViewById(R.id.llmain);
tb = new TableLayout(MainActivity.this);
tb.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
tb.setGravity(Gravity.CENTER);
TableRow tr = new TableRow(MainActivity.this);
ImageButton ima = new ImageButton(MainActivity.this);
ImageButton imr = new ImageButton(MainActivity.this);
TextView tvin = new TextView(this);
TableRow.LayoutParams trp = new TableRow.LayoutParams();
trp.setMargins(0, 0, 0, 10);
tr.setLayoutParams(trp);
tr.setGravity(Gravity.CENTER);
ima.setBackgroundColor(Color.TRANSPARENT);
ima.setImageResource(R.drawable.add);
imr.setBackgroundColor(Color.TRANSPARENT);
imr.setImageResource(R.drawable.remove);
tvin.setWidth(100);
tvin.setHeight(45);
tvin.setGravity(Gravity.CENTER);
tvin.setText(sil[i]);
tvin.setBackgroundColor(Color.rgb(200, 0, 255));
tr.addView(ima);
tr.addView(tvin);
tr.addView(imr);
tb.addView(tr);
items.addView(tb);
I tried using this
tvin.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
and this
tvin.setWidth(LayoutParams.FILL_PARENT);
tvin.setHeight(LayoutParams.FILL_PARENT);
but none of these work.
Try:
tvin.setLayoutParams(new TableRow.LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
and remove the tvin.setWidth and height.
You should always set the layout params of view's parent, TableRow in this case.
MATCH_PARENT makes no difference but it's a new name and you should be using it instead of FILL_PARENT.
In this Line u have to use height and width .. TableRow.LayoutParams trp = new TableRow.LayoutParams(); Like this
TableRow row = new TableRow(context);
row.setLayoutParams(new android.widget.TableRow.LayoutParams(android.widget.TableRow.LayoutParams.FILL_PARENT,
android.widget.TableRow.LayoutParams.WRAP_CONTENT));
Try to use the LinearLayout.LayoutParams
TextView tvin = new TextView(this);
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
tvin.setLayoutParams(llp);
I'm trying to adding TableRows to a TableLayout, which is working fantastically. However, I'm running into some problems with layout parameters. The spacing between the TextViews within a TableRow isn't working out like I thought it would.
My current code looks as follows.
paymentTable = (TableLayout) findViewById(R.id.paymentTable);
for(i = 0; i < cursor.getCount(); i++) {
TableRow row = new TableRow(this);
TextView payAmount = new TextView(this);
payAmount.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.KEY_AMOUNT)));
payAmount.setPadding(payAmount.getPaddingLeft(),
payAmount.getPaddingTop(),
textView.getPaddingRight(),
payAmount.getPaddingBottom());
TextView payDate = new TextView(this);
payDate.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.KEY_DATE)));
row.addView(payDate);
row.addView(payAmount);
paymentTable.addView(row, new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
cursor.moveToNext();
}
Afterwards, the TableLayout looks something along the lines of:
January$500
February$500
March$405
But I want it to look like:
January $500
February $500
March $405
To clarify things, I want each new TableRow and the TextViews it contains to inherit layout properties of an existing TableRow and TextView(s).
yawus this is a good tutorial will help you set the table layout
http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/
this is the xml layout
http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/6/
this is the activity code
http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/8/
TableRow tableRow= new TableRow(this);
ArrayList<Object> row = data.get(position);
TextView idText = new TextView(this);
idText.setText(row.get(0).toString());
tableRow.addView(idText);
TextView textOne = new TextView(this);
textOne.setText(row.get(1).toString());
tableRow.addView(textOne);
TextView textTwo = new TextView(this);
textTwo.setText(row.get(2).toString());
tableRow.addView(textTwo);
dataTable.addView(tableRow);
You need to add a RelativeLayout to each Table
TableRow row = new TableRow(this);
row.setId(tag);
// Creating a new RelativeLayout
RelativeLayout relativeLayout = new RelativeLayout(this);
// as the parent of that RelativeLayout is a TableRow you must use TableRow.LayoutParams
TableRow.LayoutParams rlp = new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.MATCH_PARENT);
rlp.setMargins(0, 0, 0, 0);
row.addView(relativeLayout, rlp);
Then you add your TextView to the RelativeLayout. Like this
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
TextView payAmount = new TextView(this);
//lp.setMargins(left, top, right, bottom)
lp.setMargins(0, 0, 16, 0);
lp.addRule(RelativeLayout.ALIGN_LEFT);
payAmount.setLayoutParams(lp);
relativeLayout.addView(payAmount);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
TextView payDate = new TextView(this);
//lp.setMargins(left, top, right, bottom)
lp.setMargins(0, 0, 16, 0);
lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
payDate.setLayoutParams(lp);
relativeLayout.addView(payDate);
This is the way I handle positioning interface components within a table row.
I have been searching everywhere for an answer to this question. I'm new to Android and attempting to add items to a relative layout programmatically through java instead of xml. I have created a test class to try it out but the items keep stacking instead of formatting correctly. I simply want one TextView under the other for now (eventually I will use the left of and right of parameters but I am starting simple. What am I missing?
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ScrollView sv = new ScrollView(this);
RelativeLayout ll = new RelativeLayout(this);
ll.setId(99);
sv.addView(ll);
TextView tv = new TextView(this);
tv.setText("txt1");
tv.setId(1);
TextView tv2 = new TextView(this);
tv2.setText("txt2");
tv2.setId(2);
RelativeLayout.LayoutParams lay = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lay.addRule(RelativeLayout.ALIGN_PARENT_TOP);
ll.addView(tv, lay);
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
p.addRule(RelativeLayout.ALIGN_BOTTOM, tv.getId());
ll.addView(tv2, p); this.setContentView(sv);};
p.addRule(RelativeLayout.ALIGN_BOTTOM, tv.getId());
This line means that the the bottom of tv2 is aligned with the bottom of tv- in other words, they will cover each other up. The property you want is presumably RelativeLayout.BELOW . However, I strongly recommend using xml for this instead.
Use:
p.addRule(RelativeLayout.BELOW, tv.getId());
you are missing various things, first the ScrollView has no measures, set it with LayoutParams.FILL_PARENT or WRAP_CONTENT, second; it TextView1 are misplaced so TextView2, set TextView1 position with lay.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ScrollView sv = new ScrollView(this);
RelativeLayout ll = new RelativeLayout(this);
ll.setId(99);
sv.addView(ll, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
TextView tv = new TextView(this);
tv.setText("txt1");
tv.setId(1);
TextView tv2 = new TextView(this);
tv2.setText("txt2");
tv2.setId(2);
RelativeLayout.LayoutParams lay = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lay.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
ll.addView(tv, lay);
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
p.addRule(RelativeLayout.ALIGN_BOTTOM, tv.getId());
ll.addView(tv2, p);
this.setContentView(sv);};
HI , why my text is not coming at the bottom evethough i have given tParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
Here is my code please help,
footScroll_relative = new RelativeLayout(this);
footScroll_scrollView = new ScrollView(this);
footScroll_horizontalScrollView = new HorizontalScrollView(this);
test_text = new TextView(this);
footScroll_relative.setLayoutParams(new LinearLayout.LayoutParams(android.view.ViewGroup.LayoutParams.FILL_PARENT,android.view.ViewGroup.LayoutParams.FILL_PARENT));
LayoutParams tParams = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
tParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
footScroll_horizontalScrollView.setLayoutParams(new LinearLayout.LayoutParams(android.view.ViewGroup.LayoutParams.FILL_PARENT,android.view.ViewGroup.LayoutParams.FILL_PARENT));
footScroll_scrollView.setLayoutParams(tParams);
test_text.setText("Ramesh ");
footScroll_horizontalScrollView.addView(test_text);
footScroll_scrollView.addView(footScroll_horizontalScrollView);
footScroll_relative.addView(footScroll_scrollView);
setContentView(footScroll_relative);
this is an example of how to
TextView tView = ((TextView)view.findViewById(R.id.seekBarFilterLabel));
LayoutParams tParams = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
tParams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
tView.setLayoutParams(tParams);
Hope this helps
EDIT: well, in your previuos unedited question you ask how to align the text at a RelativaLayout parent bottom, but here you are adding the TextView inside a HorizontalScrollView, wich is incorrect, the rule RelativeLayout.ALIGN_PARENT_BOTTOM are only valid if you are adding a view inside a RelativeLayout, not inside of ScrollView.
