I want to put my number button like that. This is my code:
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
LinearLayout layout2 = new LinearLayout(this);
layout2.setOrientation(LinearLayout.HORIZONTAL);
TextView titleView = new TextView(this);
titleView.setText("Hello World!");
layout.addView(titleView);
android.widget.LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.FILL_PARENT, 1);
android.widget.TableLayout.LayoutParams params = new TableLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.FILL_PARENT, 1);
Button btnConnect = new Button(this);
btnConnect.setText("Connect");
btnConnect.setLayoutParams(param);
layout2.addView(btnConnect);
Button btnDisconnect = new Button(this);
btnDisconnect.setText("Disconnect");
layout2.addView(btnDisconnect);
btnDisconnect.setLayoutParams(param);
layout.addView(layout2);
TableLayout tblLayout = new TableLayout(this);
tblLayout.setOrientation(TableLayout.HORIZONTAL);
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);
this complies:
In order to make my columns like that. I used this code:
android.widget.TableLayout.LayoutParams params = new TableLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.FILL_PARENT, 1);
tblLayout.setLayoutParams(param);
but there's no change. What do i need to do? Is that Layoutparams not enough to do that?
You need to set the widths of layout, layout2, tblLayout, each tblRow, and tr to MATCH_PARENT and each Button must have an equal layout_weight.

i wanted to add textview and edittext params by code.
here is my code
private void draw_table() {

for (int i = 0; i < 2; i++) {
TableRow row = new TableRow(this);
TableRow.LayoutParams lp = new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT);
row.setLayoutParams(lp);
// setting textVIEW
textview = new TextView(this);
textview.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
//textview.setPadding(0, 0, 5, 10);
//textview.setTextAppearance(this,
// android.R.style.TextAppearance_Medium);
textview.setText("Hello");
// setting editText
edittext = new EditText(this);
edittext.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
//edittext.setEms(10);
//edittext.setHint("gpa");
//edittext.setInputType(InputType.TYPE_CLASS_NUMBER);
row.addView(textview);
row.addView(edittext);
ll.addView(row, i);
}
}
but nothing appear on the screen. whats wrong in this code ?thanks in advance :)
Use TableRow.LayoutParams to set your widgets LayoutParams. Like this
textview.setLayoutParams(new TableRow.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
also see how add and delete rows to table layout in java programically
i'm writing progrmicaly adding Linearlayout and Textview into ScrollView. but my ScrollView could not scroll to height.
My programicall Code:
if (cursor.moveToFirst()) {
do {
String last_ID = cursor.getString(cursor.getColumnIndex("lastId"));
String smsBody = cursor.getString(cursor.getColumnIndex("smsBody"));
String senderName = cursor.getString(cursor.getColumnIndex("senderName"));
String date[] = cursor.getString(cursor.getColumnIndex("receiveDate")).split("/");
CalendarTool ct =
new CalendarTool(
Integer.valueOf(date[0]),
Integer.valueOf(date[1]),
Integer.valueOf(date[2])
);
String IranianDate = ct.getIranianDate();
ScrollView SV =new ScrollView(this);
LinearLayout ll = new LinearLayout(this);
ll.setBackgroundColor(Color.parseColor("#f7cbad"));
ll.setOrientation(LinearLayout.VERTICAL);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.FILL_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT
);
params.setMargins(0, 0, 0, 10);
ll.setLayoutParams(params);
TextView TV_IranianDate = new TextView(this);
TV_IranianDate.setText(IranianDate);
TV_IranianDate.setTextColor(Color.parseColor("#ffffff"));
TV_IranianDate.setLayoutParams(
new ViewGroup.LayoutParams
(ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT)
);
ll.addView(TV_IranianDate);
TextView TV_smsBody = new TextView(this);
TV_smsBody.setText(smsBody);
TV_smsBody.setGravity(Gravity.RIGHT);
TV_smsBody.setLayoutParams(
new ViewGroup.LayoutParams
(ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT)
);
TV_smsBody.setPadding(5, 5, 5, 5);
ll.addView(TV_smsBody);
TextView TV_spacer2 = new TextView(this);
TV_spacer2.setBackgroundColor(Color.parseColor("#000000"));
TV_spacer2.setLayoutParams(
new ViewGroup.LayoutParams
(ViewGroup.LayoutParams.FILL_PARENT,
1)
);
ll.addView(TV_spacer2);
SV.addView(ll);
((LinearLayout) linearLayout).addView(SV);
} while (cursor.moveToNext());
}
I guess the problem is the ScrollView object. You should use HorizontalScrollView instead, like this for example:
HorizontalScrollView SV = new HorizontalScrollView(this);
SV.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));
like described in the API:
ScrollView only supports vertical scrolling. For horizontal scrolling, use HorizontalScrollView.
Dynamic linearlayout weight is not setting properly, refer the following coding
LinearLayout.LayoutParams mainparams = new LinearLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT,
1.0f);
mainparams.setMargins(0, 10, 0, 0);
LinearLayout li = new LinearLayout(Appointmentdetails.this);
li.setOrientation(LinearLayout.HORIZONTAL);
li.setLayoutParams(mainparams);
LinearLayout text = new LinearLayout(Appointmentdetails.this);
text.setWeightSum(1);
LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT,
2.0f);
text.setLayoutParams(lparams);
tv = new TextView(this);
tv.setTextSize(18);
tv.setTypeface(MyriadPro);
tv.setLayoutParams(lparams);
tv.setText(Alldata.question.get(i).getgQuestion());
tv.setSingleLine();
tv.setPadding(25, 0, 0, 0);
tv.setMarqueeRepeatLimit(10);
tv.setEllipsize(TruncateAt.MARQUEE);
tv.setSelected(true);
text.addView(tv);
li.addView(text);
LinearLayout Spi = new LinearLayout(Appointmentdetails.this);
Spi.setWeightSum(1);
LinearLayout.LayoutParams lparams1 = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT,
1f);
Spi.setLayoutParams(lparams1);
RadioGroup rg = new RadioGroup(Appointmentdetails.this);
// rg.setLayoutParams(lparams1);
gAnswerList.add("Select");
for (int j = 0; j < helptext.split(Expressions).length; j++) {
RadioButton rb = new RadioButton(Appointmentdetails.this);
rb.setText(helptext.split(Expressions)[j].toString());
rb.setId(j);
rb.setLayoutParams(lparams1);
rg.addView(rb);
}
rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
public void onCheckedChanged(RadioGroup rg, int checkedId) {
for (int i = 0; i < rg.getChildCount(); i++) {
RadioButton rb = (RadioButton) rg.getChildAt(i);
if (rb.getId() == checkedId) {
CharSequence text = rb.getText();
mSelectedRadioValue = text + ",";
gAnswerList.set(i2, text.toString());
// do something with text
return;
}
}
}
});
Spi.addView(rg);
li.addView(Spi);
mQuestionLayout.addView(li);
}
}
This is how i have added a radio button inside the dynamic linear layout, i dont know whats wrong in my coding its not properly aligned, kindly suggest me to get the solution. Thanks in advance.
I would attempt setting the layout params to center. Your pretty much just giving them free flow and setting wherever they like with WRAP_CONTENTS. Yes, they will not fill the entire screen which is not what you want, but try passing something like Try doing something like this
LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT,
2.0f, lparams.Gravity.CENTER);
Try this for RadioButton and text alignment
LinearLayout.LayoutParams mainparams = new LinearLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT
);
LinearLayout li = new LinearLayout(Appointmentdetails.this);
li.setOrientation(LinearLayout.HORIZONTAL);
li.setLayoutParams(mainparams);
li.setWeightSum(2);
LinearLayout.LayoutParams mainparams1 = new LinearLayout.LayoutParams(
0, LayoutParams.WRAP_CONTENT
);
mainparams1.weight = 1;
TextView tv = new TextView(this);
tv.setTextSize(18);
tv.setLayoutParams(mainparams1);
tv.setText("text ");
RadioGroup rg = new RadioGroup(Appointmentdetails.this);
rg.setLayoutParams(mainparams1);
rg.setOrientation(RadioGroup.VERTICAL);
for (int j = 0; j < helptext.split(Expressions).length; j++) {
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT
);
RadioButton rb = new RadioButton(Appointmentdetails.this);
rb.setText(helptext.split(Expressions)[j].toString());
rb.setId(j);
rb.setLayoutParams(params );
rg.addView(rb);
}
li.addView(tv);
li.addView(rg);
How can I do the following:
Create a row in a TableLayout programmatically
Create three cells in the row
Add arbitrary text in each cell
Thanks for your help!
Try this..
TableLayout tableLayout = new TableLayout(this);
tableLayout.setStretchAllColumns(true);
tableLayout.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.FILL_PARENT));
tableLayout.setWeightSum(3);
for (int i = 0; i < 3; i++) {
TableRow tableRow = new TableRow(this);
tableRow.setGravity(Gravity.CENTER);
tableRow.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.FILL_PARENT, 1.0f));
for (int j = 0; j < 3; j++) {
TextView button = new TextView(this);
final int buttonNumber = (j + i * 4);
button.setText("" + buttonNumber);
button.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.FILL_PARENT));
tableRow.addView(button);
}
tableLayout.addView(tableRow);
}
main_lay.addView(tableLayout);
TableLayout table = (TableLayout) findViewById(R.id.TableName);
TableRow tableRow = new TableRow(context);
tableRow.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
TextView cell1= new TextView(getApplicationContext());
cell1.setText("one");
cell1.setTextColor(Color.BLACK);
cell1.setTextSize(16f);
cell1.setTypeface(tf);
TextView cell2= new TextView(getApplicationContext());
cell2.setText("two");
cell2.setTextColor(Color.BLACK);
cell2.setTextSize(16f);
cell2.setTypeface(tf);
TextView cell3= new TextView(getApplicationContext());
cell3.setText("three");
cell3.setTextColor(Color.BLACK);
cell3.setTextSize(16f);
cell3.setTypeface(tf);
tableRow.addView(cell1);
tableRow.addView(cell2);
tableRow.addView(cell3);
talbe.addView(tableRow , new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.WRAP_CONTENT));
If you want you can use a function like this to update your tableLayout which adds a new row with some text.
private void addRowToTableLayout(TableLayout tableLayout, String text){
TableRow tr = new TableRow(MyActivity.this);
//if you want you can customize the table row
tr.setBackgroundColor(getResources().getColor(R.color.backgroundColor));
tr.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT));
TextView textView = new TextView(MyActivity.this);
//if you want you can customize the textview also
textView.setText(text);
tr.addView(textView);
tableLayout.addView(tr, new TableLayout.LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
}
