I am trying to add multiple components into linear layout programatically. Here are the codes:
private View createCalloutView(Graphic graphic) {
LinearLayout ret = new LinearLayout(this);
ret.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
TextView reportContent = new TextView(this);
reportContent.setText(eventName + "\n" + eventBy + "\n" + eventAddress + "\n" + eventDesc
+ "\n" + eventDate + "\n" + eventTime);
reportContent.setTextColor(Color.BLACK);
reportContent.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 12);
reportContent.setPadding(1, 0, 1, 0);
Button viewDtlEventBtn = new Button(this);
viewDtlEventBtn.setText("View details");
viewDtlEventBtn.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
ret.addView(reportContent);
ret.addView(viewDtlEventBtn);
return ret;
}
With these codes, I only manged to see the textview and my button is missing. Any ideas? Thanks in advance.
that depends on how do you want to arrange the items in the LinearLayout. If you want to arrange the button next to the TextView, then, probably, the button width should be WRAP_CONTENT instead of FILL_PARENT. If you want to show the button under the TextView, then, your LinearLayout should have vertical as orientation (default is horizontal). Imo, the easiest way is to have your layout defined in a xml file. At least you can see the output at compile time, and use an inflater to retrieve the View's object at run time
The default orientation of linear layout is horizontal. You need to set the orientation first.
LinearLayout ret = new LinearLayout(this);
ret.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
ret.setOrientation(LinearLayout.VERTICAL);
This will solve your problem of missing button.
You have forgot to set Layout Orientation for Linear Layout, just set it as below:
ret.setOrientation(LinearLayout.VERTICAL);

Im trying to create LinearLayout programmaticaly and I would want to allow user to put number range.
Now it looks like that:
But when I try to enter more digits eg. 100, 101 or 3,50 it dissapears.
I guess there is not enough space for it to be shown, but I can't figure out what is wrong. Generally I don't want to move + and - buttons when the user enters some values so I guess it should be hardcoded. There would be up to 5-6 digits only, so I need space just for it, but as I said, I can't find the place, where I can change it as my changes eiter move entire layout or doesn't do anything.
Below is my code:
LinearLayout horizontalLayout = new LinearLayout(mContext);
LinearLayout titleLayout = new LinearLayout(mContext);
LinearLayout countLayout = new LinearLayout(mContext);
ImageButton buttonAdd = new ImageButton(mContext);
ImageButton buttonSub = new ImageButton(mContext);
TextView titleTextView = new TextView(mContext);
EditText countEditText = new EditText(mContext);
final int[] currentCount = {defaultValue};
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
LinearLayout.LayoutParams linearLayout = new LinearLayout.LayoutParams(0, LayoutParams.MATCH_PARENT, 1f);
LinearLayout.LayoutParams utilParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
horizontalLayout.setOrientation(LinearLayout.HORIZONTAL);
horizontalLayout.setLayoutParams(params);
utilParams.gravity = Gravity.CENTER_VERTICAL;
titleLayout.setOrientation(LinearLayout.HORIZONTAL);
titleLayout.setPadding(0, pxFromDp(mContext, 16),0, pxFromDp(mContext, 16));
titleLayout.setLayoutParams(linearLayout);
countLayout.setOrientation(LinearLayout.HORIZONTAL);
countLayout.setPadding(0, pxFromDp(mContext, 16),0, pxFromDp(mContext, 16));
countLayout.setLayoutParams(linearLayout);
utilParams.setMargins(0,0,pxFromDp(mContext, 16f),0);
titleTextView.setTextSize(TypedValue.COMPLEX_UNIT_SP,16);
titleTextView.setText(title);
titleTextView.setLayoutParams(utilParams);
titleLayout.addView(titleTextView);
utilParams.setMargins(pxFromDp(mContext, 16f),0,pxFromDp(mContext, 16f),0);
buttonSub.setImageResource(R.drawable.ic_remove);
buttonSub.setLayoutParams(utilParams);
buttonSub.setBackgroundColor(mContext.getResources().getColor(R.color.fsm_survey_btn));
buttonSub.setColorFilter(ContextCompat.getColor(mContext, R.color.fsm_white), android.graphics.PorterDuff.Mode.SRC_IN);
countLayout.addView(buttonSub);
countEditText.setTextSize(TypedValue.COMPLEX_UNIT_SP, 16);
countEditText.setText(String.valueOf(defaultValue));
countEditText.setLayoutParams(linearLayout);
countEditText.setGravity(Gravity.CENTER);
countLayout.addView(countEditText);
buttonAdd.setImageResource(R.drawable.ic_add_24);
buttonAdd.setLayoutParams(utilParams);
buttonAdd.setBackgroundColor(mContext.getResources().getColor(R.color.fsm_survey_btn));
buttonAdd.setColorFilter(ContextCompat.getColor(mContext, R.color.fsm_white), android.graphics.PorterDuff.Mode.SRC_IN);
countLayout.addView(buttonAdd);
horizontalLayout.addView(titleLayout);
horizontalLayout.addView(countLayout);
What you can do is to create separate LinearLayout.LayoutParams for the edittext and add addTextChangedListener to that edit text and on onTextChanged
write switch statement to increase the weight of the edittext on increase of length of the input number.
How can I put that little number in the same column (textView) or how can I add two of them .
I have tried linearlayout horizantal but it did not worked How I want that text view to be look like;
ı want to add number like this image
//this my textView for adding to rows
txtColumnArray[i] = new TextView(this);
txtColumnArray[i].setTextColor(Color.BLUE);
txtColumnArray[i].setAllCaps(true);
txtColumnArray[i].setGravity(Gravity.CENTER);
txtColumnArray[i].setTypeface(Typeface.DEFAULT.DEFAULT_BOLD);
txtColumnArray[i].setTextSize(TypedValue.COMPLEX_UNIT_SP, 20f);
// my last try is spanable but it is not working , I thought it may be
// coz of textView properties but couldnt find it.
spanableForQuestionNumbers[questionNumbersCount] = new SpannableString(questionNumbersCount + " " + LetterFormat[count]);
spanableForQuestionNumbers[questionNumbersCount].setSpan(new SuperscriptSpan(), 0, 1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
txtColumnArray[i].setText(spanableForQuestionNumbers[questionNumbersCount]);
trCrosswordRow.addView(txtColumnArray[i]);
I read some thread in this topic, but I have not found the solution.
I would like to use the scrollHorizontally attribute on a TextView, but from Java code.
Here's what I tried:
nameTextView = new TextView(context);
nameTextView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 20);
nameTextView.setId(R.id.header_text_id);
nameTextView.setGravity(Gravity.CENTER | Gravity.LEFT);
nameTextView.setSingleLine();
nameTextView.setHorizontallyScrolling(true);
nameTextView.setEllipsize(TextUtils.TruncateAt.MARQUEE);
nameTextView.setFocusableInTouchMode(true);
nameTextView.setMarqueeRepeatLimit(-1);
nameTextView.setFocusable(true);
Typeface tf = Typeface.createFromAsset(context.getAssets(), "fonts/robotocondensed.ttf");
nameTextView.setTypeface(tf);
nameTextView.setTextColor(getResources().getColor(android.R.color.white));
I set the text later. The text does not scroll, what can be the problem here?
android:maxLines = "AN_INTEGER"
android:scrollbars = "vertical"
Then set:
yourTextView.setMovementMethod(new ScrollingMovementMethod())
excelent article about how to make an horizontal scrollable textview in android, It works!!!

I have hit a problem when trying to align my text to the top of a text view dynamically. I have a method that creates textviews dynamically. I have set the gravity of the text view to Gravity.TOP. Which a believe should place the text at the very top of the textView object. However when I run the project there is a gap of about 2 lines of text from the top of the object. I can work around this by changing the height of the textView but I would rather it loaded in an set the size depending on how much text there is too load into the textView.
Here is my function, it works well and does what it is supposed to do:
public void addItems(LinearLayout page,int id,String text,int row){
LinearLayout item = new LinearLayout(this);
item.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT));
TextView itemNum = new TextView(this);
//itemNum.setLayoutParams(new ViewGroup.LayoutParams(50,50));
itemNum.setWidth(50);
itemNum.setTextSize(40);
itemNum.setTextAppearance(getApplicationContext(), R.style.large_text);
itemNum.setLeft(0);
itemNum.setText(row+":");
LayoutParams numParams = new LinearLayout.LayoutParams(70, 70);
numParams.setMargins(25, 0, 0, 0);
TextView itemDetails = new TextView(this);
itemDetails.setLayoutParams(new ViewGroup.LayoutParams(150,LayoutParams.WRAP_CONTENT));
itemDetails.setText(text);
itemDetails.setWidth(100);
itemDetails.setLeft(5);
itemDetails.setRight(5);
itemDetails.setTop(0);
itemDetails.setVisibility(View.VISIBLE);
itemDetails.setGravity(itemDetails.getGravity() | Gravity.TOP);
itemDetails.setPadding(0,0,0,0);
Button delete = new Button(this);
//delete.setLayoutParams(new ViewGroup.LayoutParams(50,50));
delete.setText("Delete");
LayoutParams btnParams = new LinearLayout.LayoutParams(70, 70);
btnParams.setMargins(0, 0, 15, 0);
item.addView(itemNum,numParams);
item.addView(itemDetails);
item.addView(delete,btnParams);
page.addView(item);
Log.d("Loop","Loop is adding function in");
}
If anybody can see where I have gone wrong I would really appreciate it. The method above may seem very long winded but I am new to Java.
Not sure if it will help but here is my string to show in the textView:
String formatText = lat + ", " + lng + " /n" + result;
I have the following code:
TextView name = new TextView(this);
name.setText(venues.get(j).name);
name.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView address = new TextView(this);
address.setText(venues.get(j).getFullAddress());
address.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
/* Add Button to row. */
tr.addView(name);
tr.addView(address);
And now it gives me a layout like this:
I want the TextView to be in separate lines. How do I do this?
First of all, don't use LayoutParams for Views that are going into a TableRow... use TableRow.LayoutParams.
Second (pls tell me if I misunderstood your question), if you want your edittexts to show up on different lines... that means you want them on different rows. In other words, don't put them into the same TableRow. You can put them into separate TableRows or use a LinearLayout.
Try adding addr to another TableRow.
TextView name = new TextView(this);
TextView addr = new TextView(this);
name.setText("Name");
addr.setText("Addr");
TableRow tableRow1 = (TableRow) findViewById(R.id.tableRow1);
TableRow tableRow2 = (TableRow) findViewById(R.id.tableRow2);
tableRow1.addView(name);
tableRow2.addView(addr);
