Is it possible to use TableRow like this:
That is array of TableRows. This must be inside table layout where table layout is nested inside linear layout.
TableRow[] tr = new TableRow[dimension];
Yes... this is abosutely possible in Android . TableRow is a class and you are trying to make an array of objects of a class .
Yes Absolutely Possible. check this link & try this code.
public void init(){
TableLayout ll = (TableLayout) findViewById(R.id.displayLinear);
for (int i = 0; i <2; i++) {
TableRow row= new TableRow(this);
TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT);
row.setLayoutParams(lp);
checkBox = new CheckBox(this);
tv = new TextView(this);
addBtn = new ImageButton(this);
addBtn.setImageResource(R.drawable.add);
minusBtn = new ImageButton(this);
minusBtn.setImageResource(R.drawable.minus);
qty = new TextView(this);
checkBox.setText("hello");
qty.setText("10");
row.addView(checkBox);
row.addView(minusBtn);
row.addView(qty);
row.addView(addBtn);
ll.addView(row,i);
}}

I have a LinearLayout inside a FrameLayout for tab purposes. And I'm trying to add TableRow's to the LinearLayout in the code.
LinearLayout testLayout = (LinearLayout)findViewById(R.id.testLayout);
TableRow tableRow = new TableRow(this);
tableRow.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT));
This gets my LinearLayout and creates a TableRow to the specifications I want. I know this part is working.
TextView textOne = new TextView(this);
textOne.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
textOne.setText("One");
TextView textTwo = new TextView(this);
textTwo.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
textTwo.setText("Two");
Here I make my two TextViews with no problem.
tableRow.addView(textOne);
tableRow.addView(textTwo);
testLayout.addView(tableRow, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
Here is where I assume everything goes wrong. What happens is it only shows the textTwo. I don't know why it's not showing both of them in order like a normal TableRow would in XML. And I repeat, this must be done in code.
Please help, thank you.
Have you imported this import android.widget.TableRow.LayoutParams
Below code works for me
TableLayout tl = (TableLayout) findViewById(R.id.spreadsheet);
TableRow tr = new TableRow(this);
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
TextView tvLeft = new TextView(this);
tvLeft.setLayoutParams(lp);
tvLeft.setBackgroundColor(Color.WHITE);
tvLeft.setText("OMG");
TextView tvCenter = new TextView(this);
tvCenter.setLayoutParams(lp);
tvCenter.setBackgroundColor(Color.WHITE);
tvCenter.setText("It");
TextView tvRight = new TextView(this);
tvRight.setLayoutParams(lp);
tvRight.setBackgroundColor(Color.WHITE);
tvRight.setText("WORKED!!!");
tr.addView(tvLeft);
tr.addView(tvCenter);
tr.addView(tvRight);
tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
tl.addView(tr, new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.WRAP_CONTENT));
I think you want to create your TextView dynamically and should're getting error "removeView () parent." Here is a good solution for that:
TableView tlSkills = (TableView) findViewById(R.id.myTableView);
if(listSkills.size() > 0) {
TableRow tableRow = new TableRow(getContext());
int i = 0;
for (Skills s : listSkills) {
TextView textView = new TextView(getContext());
textView.setText("" + s.getName());
tableRow.addView(textView);
if(i > 0) {
tlSkills.removeView(tableRow);//this is to avoid the error I mentioned above.
}
tlSkills.addView(tableRow);
i++;
}
}
This question already has an answer here:
How can i put my buttons like that?
(1 answer)
Closed 9 years ago.
Hello i want to put my number buttons(1 to 9) like that
but its now like that:
This is my code:
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
layout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT));
LinearLayout layout2 = new LinearLayout(this);
layout2.setOrientation(LinearLayout.HORIZONTAL);
layout2.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT));
TextView titleView = new TextView(this);
titleView.setText("Table Layout");
titleView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
layout.addView(titleView);
LinearLayout.LayoutParams param2 = new LinearLayout.LayoutParams(
0, LinearLayout.LayoutParams.WRAP_CONTENT, 1);
Button btnConnect = new Button(this);
btnConnect.setText("Connect");
btnConnect.setLayoutParams(param2);
layout2.addView(btnConnect);
TextView titleViewSpace = new TextView(this);
titleViewSpace.setLayoutParams(param2);
layout2.addView(titleViewSpace);
Button btnDisconnect = new Button(this);
btnDisconnect.setText("Disconnect");
btnDisconnect.setLayoutParams(param2);
layout2.addView(btnDisconnect);
layout.addView(layout2);
TableLayout tblLayout = new TableLayout(this);
tblLayout.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT,TableLayout.LayoutParams.MATCH_PARENT));
TableRow tblrow = null;
for (int i = 1; i <= 9; i++) {
if (i % 3 == 1) {
tblrow = new TableRow(this);
tblLayout.addView(tblrow);
}
Button b = new Button(this);
b.setText("" + i);
tblrow.addView(b);
}
TableRow tr = new TableRow(this);
Button btnZero = new Button(this);
btnZero.setText("0");
Button btnHash = new Button(this);
btnHash.setText("#");
Button btnStar = new Button(this);
btnStar.setText("*");
tr.addView(btnZero);
tr.addView(btnHash);
tr.addView(btnStar);
tblLayout.addView(tr);
layout.addView(tblLayout);
setContentView(layout);
In order to have above view, i put buttons this layout
new LayoutParams(0,LayoutParams.WRAP_CONTENT,1)
However, when i put this layout to buttons(1 to 9), buttons in loop disappear. What might be the solution?
You can look up weight sum and layout weight in google. These two properties will make the buttons take up the whole space of the screen.
In My application i want to create the layout as like below image:
So How to make it possible ?
I have done Something like below code:
public void showResult()
{
List<TextView> textListWord = new ArrayList<TextView>(tempEmployerList.size());
List<TextView> textListAnswer = new ArrayList<TextView>(tempEmployerList.size());
List<TextView> imageListAnswer = new ArrayList<TextView>(tempEmployerList.size());
for(int i = 0; i<=tempEmployerList.size()-1; i++)
{
LinearLayout innerLayout = new LinearLayout(this);
innerLayout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
innerLayout.setBackgroundColor(0x00000000);
// set the Multiple TextView
TextView mHeading = new TextView(getApplicationContext());
TextView middleValue = new TextView(getApplicationContext());
TextView aImageView = new TextView(getApplicationContext());
mHeading.setText("\n"+"1");
//mHeading.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
mHeading.setTextColor(0xFFFF0000);
mHeading.setPadding(3, 0, 0, 0);
middleValue.setText("\n"+"2");
//middleValue.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
middleValue.setTextColor(0xFFFF0000);
middleValue.setGravity(Gravity.RIGHT);
middleValue.setPadding(2, 0, 9, 0);
aImageView.setText("\n"+"3");
//aImageView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
aImageView.setGravity(Gravity.RIGHT);
aImageView.setTextColor(0xFF000000);
aImageView.setPadding(0, 0, 9, 0);
View line = new View(getApplicationContext());
//line.setOrientation(1);
line.setLayoutParams(new LayoutParams(2, android.view.ViewGroup.LayoutParams.FILL_PARENT));
line.setBackgroundColor(0xFF000000);
/**** Any other text view setup code ****/
innerLayout.addView(mHeading);
innerLayout.addView(middleValue);
innerLayout.addView(aImageView);
innerLayout.addView(line);
myLinearLayout.addView(innerLayout);
textListWord.add(mHeading);
textListAnswer.add(middleValue);
imageListAnswer.add(aImageView);
}
}
So please guide me that what more i have to do to create such view ?
Thanks.
try TableLayout and TableRow instead of LinearLayout.
You can create TableLayout in xml as well, as it, I think would be static and add TableRows. To Create a TableLayout in Java use,
TableLayout tblLayout=new TableLayout(this);
Set LayoutParams and other properties of table layout in java, like I am setting LayoutParams:
LayoutParams params=new LayoutParams(LayoutParams.Fill_Parent, LayoutParams.Wrap_Content);
tblLayout.setLayoutParams(params);
Create a loop for TableRows creation and insertion:
for(int i=0;i<arrList1.size();i++)
{
TableRow row=new TableRow(this);
row.setLayoutParams(params);
TextView lbl1=new TextView(this);
lbl1.setText(arrList1.get(i));
row.addView(lbl1);
TextView lbl2=new TextView(this);
lbl2.setText(arrList2.get(i));
row.addView(lbl2);
TextView lbl3=new TextView(this);
lbl3.setText(arrList3.get(i));
row.addView(lbl3);
tblLayout.addView(row);
}
I am trying to create a table from a 2-D array of strings. However, I suck in creating views in code, so for some reason my image is never visible and my textviews won't break into multilines, instead they chop of the text.
Also, I put id on every textview in my code, when someone click the textview, I was hoping I could use that ID to identify whick row was clicked. Unfortunately that wasn't the case.
Are there any good ways to identify correct row?
Regards
for (int current=0; current<cityArr.length; current++) {
TableRow tr = new TableRow(this);
tr.setId(100+current);
tr.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView labelTV = new TextView(this);
labelTV.setId(current);
labelTV.setText(cityArr[current][0]);
labelTV.setTextColor(Color.BLACK);
labelTV.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tr.addView(labelTV);
ImageView mapView = new ImageView(this);
mapView.setImageResource(R.drawable.list_icon_map);
mapView.setLayoutParams(new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT, 5));
tr.addView(mapView);
tlcity.addView(tr, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
public class MainActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ScrollView sv = new ScrollView(this);
TableLayout ll=new TableLayout(this);
HorizontalScrollView hsv = new HorizontalScrollView(this);
for(int i=1;i<30;i++) {
TableRow tbrow=new TableRow(this);
for(int j=1;j<=20;j++) {
TextView tv1=new TextView(this);
String s1 = Integer.toString(i);
String s2 = Integer.toString(j);
String s3 = s1+s2;
int id = Integer.parseInt(s3);
tv1.setId(id);
tv1.setText("Dynamic TextView no: "+id);
tbrow.addView(tv1);
}
ll.addView(tbrow);
}
hsv.addView(ll);
sv.addView(hsv);
setContentView(sv);
}
}
Ha, turned out to work alright with the setID() function. as long as I put the OnClickListener on the right component...
When a button is clicked, the following method is run:
public void createTableRow(View v) {
TableLayout tl = (TableLayout) findViewById(R.id.spreadsheet);
TableRow tr = new TableRow(this);
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
TextView tvLeft = new TextView(this);
tvLeft.setLayoutParams(lp);
tvLeft.setBackgroundColor(Color.WHITE);
tvLeft.setText("OMG");
TextView tvCenter = new TextView(this);
tvCenter.setLayoutParams(lp);
tvCenter.setBackgroundColor(Color.WHITE);
tvCenter.setText("It");
TextView tvRight = new TextView(this);
tvRight.setLayoutParams(lp);
tvRight.setBackgroundColor(Color.WHITE);
tvRight.setText("WORKED!!!");
tr.addView(tvLeft);
tr.addView(tvCenter);
tr.addView(tvRight);
tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
}
R.id.spreadsheet is an xml TableLayout. I can see from debugging that the method is being accessed, but nothing is drawn to the screen. What gives? Do I need to reset the Content View somehow?
As it turns out, Eclipse is not always right. Ctrl+Shift+M made the wrong import. It had import android.view.ViewGroup.LayoutParams when it should have import android.widget.TableRow.LayoutParams
Everything works fine now.
