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);

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);
}
I'm currently creating TextView like that:
LinearLayout myLayout = (LinearLayout) activity.findViewById(R.id.ll1);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams( LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
for(int l=0; l<4; l++)
{
pairs[l] = new TextView(context);
pairs[l].setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
pairs[l].setLayoutParams(lp);
pairs[l].setId(l);
pairs[l].setText("asd");
myLayout.addView(pairs[l]);
}
Now I want set this attribute to all of this TextView:
FontFamily: cursive
SetTextSize not sp but dp (RESOLVED)
SetGravity: central_horizontal (RESOLVED)
I couldn't find a way for set those attribute when I create a TextView programatically, How can I do that?
Text size in dp can be set using setTextSize(TypedValue.COMPLEX_UNIT_DIP, <float>) - see documentation [here](https://developer.android.com/reference/android/widget/TextView.html#setTextSize(int, float)).
As for the font family, I'm afraid I don't know - hopefully someone else can help you with this :)
In order to change the font family of a TextView use setTypeface
for instance:
Typeface tf = Typeface.create("cursive", Typeface.NORMAL);
for(int l=0; l<4; l++)
{
pairs[l] = new TextView(context);
pairs[l].setTypeface(tf);
...
}
Also, this may interest: How to change fontFamily of TextView in Android
You can set the font using Typeface object.
TextView tv = new TextView(context);
Typeface face = Typeface.createFromAsset(getAssets(),
"fonts/filename.ttf");
tv.setTypeface(face);
Put the font in the assets folder of your project.
I have been stuck on this issue for hours and I have no idea how to get passed it.
I have programatically created a table (no problem), but this is the issue I am having. When I create the row, I would then like to create two separate columns. As you'll see in my example, I have two different TextViews on the same line ('Type' and 'Number'). As it stands, both of them are shifted over to the left.
What I would like is for them to be in two separate columns, equally split apart centred in each column.
Here is the relevant code to what I am trying to accomplish.
TableLayout serviceLineLayout = new TableLayout(getContext());
serviceLineLayout.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.MATCH_PARENT));
TableRow firstTableRow = getFirstTableRow(getContext());
serviceLineLayout.addView(firstTableRow);
private TableRow getFirstTableRow(Context context) {
TableRow tableRow = new TableRow(context);
tableRow.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.MATCH_PARENT));
TextView typeHeader = new TextView(context);
typeHeader.setId(0);
typeHeader.setText("Type");
typeHeader.setTextSize(20);
tableRow.addView(typeHeader);
TextView numberHeader = new TextView(context);
numberHeader.setId(0);
numberHeader.setText("Number");
numberHeader.setTextSize(20);
numberHeader.setGravity(Gravity.RIGHT);
tableRow.addView(numberHeader);
return tableRow;
}
For this tablelayout defined in xml, following will be the dynamic code in corresponding java file (Activity/Fragment).
<TableLayout
android:id="#+id/fenceTableLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</TableLayout>
Activity logic for TableView
//Table Layout parameters
TableRow.LayoutParams textViewParam = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,1.0f);
TableLayout tableLayout = (TableLayout) view.findViewById(R.id.fenceTableLayout);
TableRow trHead = new TableRow(context);
LayoutParams tableRowParams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
trHead.setLayoutParams(tableRowParams);
TextView nameHead = new TextView(context);
nameHead.setText("Content left");
nameHead.setLayoutParams(textViewParam);
nameHead.setGravity(Gravity.CENTER);
trHead.addView(nameHead);
TextView detailHead = new TextView(context);
detailHead.setText("Content right");
detailHead.setGravity(Gravity.CENTER);
detailHead.setLayoutParams(textViewParam);
trHead.addView(detailHead);
tableLayout.addView(trHead);
NOTE:
Many values have been referred from resource files, You can either neglect/replicate those.
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);
