is there a way to handle long user inputs in alert dialogs? I have a small alert dialog that requires a few inputs and whenever the string input is too long, the other inputs and textviews get all squished up. Is there a way to put the string input on a different line or a way to wrap the other textfields? Im creating the alertdialog straight from code rather than XML.
LinearLayout layout = new LinearLayout(this);
EditText weight = new EditText(this);
EditText mark = new EditText(this);
TextView marktext = new TextView(this);
marktext.setText("Mark");
TextView weighttext = new TextView(this);
weighttext.setText("Weight");
mark.setInputType(InputType.TYPE_CLASS_NUMBER);
weight.setInputType(InputType.TYPE_CLASS_NUMBER);
//Assignment name input
EditText workType = new EditText(this);
workType.setInputType(InputType.TYPE_CLASS_TEXT);
TextView workTypeText = new TextView(this);
workTypeText.setText("Name of the work: ");
weight.setId(99);
mark.setId(100);
workType.setId(9999);
/*Spinner addworkspinner = new Spinner(this);
ArrayAdapter<String> addworkadapter = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_item, ClassManager.possiblework);
addworkspinner.setAdapter(addworkadapter); */
layout.addView(workTypeText);
layout.addView(workType);
layout.addView(marktext);
layout.addView(mark);
layout.addView(weighttext);
layout.addView(weight);
AlertDialog.Builder addwork = new AlertDialog.Builder(this);
addwork.setTitle("Add a piece of work");
addwork.setView(layout);
You may want to code a limit for your input text characters, wherein if it is over limit, it changes the nuumber of lines. Use (%) modulus to divide the number of characters in one certain line.
This information about
Android: Vertical alignment for multi line EditText (Text area) may also help in identifying what you need to change in EditText.

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.
I got a simple question. I am trying to create some kind of layout that would display my records from SQLite Database in separate cells. I tried to make it using TextViews, but it is not what I expect. Do you know any ideas to create 'excel like' table with headers etc? What is more i need each row to be able to select and open (My goal is to have something like catalogue with products).
final TextView dTable= (TextView) findViewById(R.id.displayTable);
final ManageDatabase md = new ManageDatabase(this);
dTable.setText("");
for(Product p: md.takeAllProducts()){
dTable.setText(dTable.getText()+"\n"+" "+p.getProductCode()+" "+p.getProductName()+" "+p.getQuantity()+" "+p.getExpireDate());
}
You can use TableLayout for it and dynamically add your content there.
First get the reference of table layout from XML file.
TableLayout myTable = (TableLayout) findViewById(R.id.mTable);
Then you can add retrieved data to the table dynamically like below
for(Product p: md.takeAllProducts()){
//create new row
TableRow tableRow = new TableRow(this);
// create new text view
TextView textView1 = new TextView(this);
textView1.setText(p.getProductCode());
//add to row
tableRow.addView(textView1);
//create another text view and add to same row
TextView textView2 = new TextView(this);
textView2.setText(p.getProductName());
tableRow.addView(textView2);
//
TextView textView3 = new TextView(this);
textView3.setText(p.getQuantity());
tableRow.addView(textView3);
//
TextView textView4 = new TextView(this);
textView4.setText(p.getExpireDate());
tableRow.addView(textView4);
}
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 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);
