I already try many ways but it seems doesn't work with me.
my code :
TableLayout tTopic=(TableLayout) findViewById(R.id.__topic);
TableRow tr = new TableRow(this);
TableLayout.LayoutParams lpt2=null;
lpt2 = new TableLayout.LayoutParams(
TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.FILL_PARENT);
lpt2.setMargins(4, 2, 4, 2);
tr.setLayoutParams(new TableRow.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
ImageView view = new ImageView(this);
view.setLayoutParams(new LayoutParams(20,30));
view.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
view.setImageResource(R.drawable.kotak);
tr.addView(view);
tTopic.addView(tr,lpt2);
Why it doesn't appear at all? but when I omitted setLayoutParams it appear as default size. Thanks for your help
Try this:
view.setLayoutParams(new TableRow.LayoutParams(20,30));
To set ImageView width programmatically do this:
view.getLayoutParams().width = 20;

I got a little problem with adding tablerows to a table layout in android.
Here's my code:
int z = 0;
for(String detail: details){
TableRow tr = new TableRow(this);
tr.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
//odd / even
if(z%2 == 0)
tr.setBackgroundColor(Color.parseColor("#F5F5F5"));
//set detail text
TextView detailText = new TextView(this);
RelativeLayout.LayoutParams dtlp = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
detailText.setTextSize(16.0f);
detailText.setTextColor(Color.parseColor("#333333"));
detailText.setPadding(20, 10, 20, 10);
detailText.setLayoutParams(dtlp);
detailText.setText(detail);
tr.addView(detailText);
detailsTable.addView(tr);
++z;
}
I cannot figure out where the problem is. The detail textview is being set but the tablerows won't show up.
a. Try changing dtlp's "width parameter" to "RelativeLayout.MATCH_PARENT"
OR
b. Before For loop block create two layout params like this.
TableLayout.LayoutParams tlps=new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.WRAP_CONTENT);
TableRow.LayoutParams trps=new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT);
In loop Replace
detailText.setLayoutParams(dtlp);
WITH
detailText.setLayoutParams(trps);
And replace
detailsTable.addView(tr);
with
detailsTable.addView(tr,tlps);
hope this helps.
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've read this article:
Setting width of Child View using Percentage
So far it works great if we set the weight and width in XML but I want to do it programmatically. I've a table in my layout (XML) and I am adding rows to it programmatically. In each row, I am adding 2 Text Views. I tried doing like this:
TableLayout tl = (TableLayout)findViewById(R.id.myTable);
for(int i = 0; i < nl.getLength(); i++){
NamedNodeMap np = nl.item(i).getAttributes();
TableRow trDetails = new TableRow(this);
trDetails.setBackgroundColor(Color.BLACK);
TextView tvInfo = new TextView(this);
tvInfo.setTextColor(Color.WHITE);
tvInfo.setGravity(Gravity.LEFT);
tvInfo.setPadding(3, 3, 3, 3);
tvInfo.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 10);
tvInfo.setText("info");
TextView tvDetails = new TextView(this);
tvDetails.setTextColor(Color.WHITE);
tvDetails.setGravity(Gravity.LEFT);
tvDetails.setPadding(3, 3, 3, 3);
tvDetails.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 10);
tvDetails.setText(np.getNamedItem("d").getNodeValue());
trDetails.addView(tvInfo, new LinearLayout.LayoutParams(0, LayoutParams.WRAP_CONTENT, 0.50f));
trDetails.addView(tvDetails, new LinearLayout.LayoutParams(0, LayoutParams.WRAP_CONTENT, 0.50f));
tl.addView(trDetails,new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
but with no luck, it shows blank screen but if I do it in XML then it shows perfectly. Please help me sorting out this issue where I am doing wrong?
Thanks
You should use TableRow.LayoutParams and not Linearlayout.LayoutParams
trDetails.addView(tvInfo, new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 0.50));
trDetails.addView(tvDetails, new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 0.50));
I'm tryin to add an ImageView into a TableRow in Java, but it always shows in blank. The image seems to be there, but it is completely white.
This is my code:
TableRow newRow = new TableRow(this);
newRow.setId(1);
LayoutParams lptr = new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
newRow.setLayoutParams(lptr);
newRow.setBackgroundColor(this.getResources().getColor(R.color.white));
ImageView pImg = new ImageView(this);
pImg.setImageDrawable(this.getResources().getDrawable(R.drawable.error));
newRow.addView(pImg);
Why does it not work?
I think you have forgotten two thing:
1) you have forgotten setContentView(view);
2) you have forgotten to add your TableRow to TableLayout
