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);

Is there any way to align the text of radio button to the top like below programmatically.
i used the below code for creating radio group
final RadioButton[] rb = new RadioButton[5];
RadioGroup rg = new RadioGroup(getActivity()); //create the RadioGroup
rg.setOrientation(RadioGroup.VERTICAL);//or RadioGroup.VERTICAL
rg.setLayoutParams(radioparams);
for (int i = 0; i < 5; i++) {
rb[i] = new RadioButton(getActivity());
rb[i].setText("Radiobtn " + i);
rb[i].setId(i + 100);
rg.addView(rb[i]);
}
layout.addView(rg);
but i get the text to the right side of each button.
final RadioButton[] rb = new RadioButton[5];
RadioGroup rg = new RadioGroup(getActivity()); //create the RadioGroup
rg.setOrientation(RadioGroup.VERTICAL);//or RadioGroup.VERTICAL
rg.setLayoutParams(radioparams);
for (int i = 0; i < 5; i++) {
rb[i] = new RadioButton(getActivity());
rb[i].setText("Radiobtn " + i);
rb[i].setId(i + 100);
rb[i].setButtonDrawable(null);
TypedArray a = getTheme().obtainStyledAttributes(R.style.AppTheme, new int[] {android.R.attr.listChoiceIndicatorSingle});
int attributeResourceId = a.getResourceId(0, 0);
Drawable drawable = getResources().getDrawable(attributeResourceId);
rb[i].setCompoundDrawablesWithIntrinsicBounds(null, null, null, drawable);
rb[i].setGravity(Gravity.CENTER | Gravity.BOTTOM);
rg.addView(rb[i]);
}
layout.addView(rg);
Try this way you can do a trick
make your layout like this
<LinearLayout
android:id="#+id/lnrView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="80dp"
android:orientation="horizontal">
</LinearLayout>
than add programatically RadioButton like this
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
LinearLayout layout = new LinearLayout(MainActivity.this);
layout.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
LinearLayout layout2 = new LinearLayout(MainActivity.this);
layout2.setOrientation(LinearLayout.VERTICAL);
LinearLayout.LayoutParams lp2 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
final ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
final TextView textView = new TextView(MainActivity.this);
int id = 0;
textView.setId(id);
textView.setTextSize(14);
textView.setTextColor(Color.rgb(0, 0, 0));
textView.setMaxEms(2);
textView.setText("NIlu");
layout2.addView(textView);
RadioButton radioButton = new RadioButton(MainActivity.this);
layout2.addView(radioButton);
layout.setLayoutParams(lp);
lnrView.addView(layout2);
}
});
I have to create like flip cart main page, so I need use more than one horizontal view how to create that programmatically in android. In that horizontal view inside Vertical orientation using images, price, product name will display in android.
Thank in Advance

I have a method that adds a textview dynamically in a linearLayout everytime I click on a button, it works good in this case, but in some other cases i wanted to call it progmmatically without clicking on a button but it doesn't work.BUT when I click on the button again, the textviews appear.
This method is contained in a fragment by the way.
Here is my code :
private void add_part() {
int width = bar.getWidth();
int child_count = ((ViewGroup) bar).getChildCount();
if (child_count == 0) {
minus_btn.setEnabled(true);
LayoutParams lparams = new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT);
TextView part = new TextView(getActivity());
part.setLayoutParams(lparams);
part.setGravity(Gravity.CENTER);
bar.addView(part);
} else if (child_count == 1) {
minus_btn.setEnabled(true);
View nextChild = ((ViewGroup) bar).getChildAt(0);
LayoutParams newparams = new LayoutParams(width / 2,
LayoutParams.FILL_PARENT);
nextChild.setLayoutParams(newparams);
LayoutParams lparams = new LayoutParams(width / 2,
LayoutParams.FILL_PARENT);
TextView part = new TextView(getActivity());
part.setLayoutParams(lparams);
bar.addView(part);
} else if (child_count > 1 && child_count < 10) {
minus_btn.setEnabled(true);
for (int i = 0; i < child_count; ++i) {
View nextChild = ((ViewGroup) bar).getChildAt(i);
LayoutParams newparams = new LayoutParams(width
/ (child_count + 1), LayoutParams.FILL_PARENT);
nextChild.setLayoutParams(newparams);
}
LayoutParams lparams = new LayoutParams(width / (child_count + 1),
LayoutParams.FILL_PARENT);
TextView part = new TextView(getActivity());
part.setLayoutParams(lparams);
bar.addView(part);
}
}
and I called it this ways :
add_part();
or
plus_btn.performClick();
Here I have to add text view programmatically based on array list size. Text views should be appear in row like continues pattern...
eg. tv1, tv2, tv3 and so on till the size of array list.
But here I am getting text views which are appearing on each other. I can't read the text on them. Here is my code:
ArrayList<String> languageNames = new ArrayList<String>();
RelativeLayout rl = (RelativeLayout)findViewById(R.id.rl);
if(languageNames.size()>0)
{
int size = languageNames.size();
TextView[] tv = new TextView[size];
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
p.addRule(RelativeLayout.BELOW, tvLocation.getId());
for(int i=0; i<size; i++)
{
tv[i] = new TextView(getBaseContext());
tv[i].setText(languageNames.get(i).toString());
tv[i].setLayoutParams(p);
tv[i].setPadding(50, 50, 0, 0);
tv[i].setTextColor(Color.parseColor("#000000"));
rl.addView(tv[i]);
}
}
else
{
}
what needs to be done so that I can get text views in appropriate manner?
Add buttons inside a LinearLayout and add this LinearLayout in the RelativeLayout.
RelativeLayout r1 = (RelativeLayout) findViewById(R.id.r1);
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
p.addRule(RelativeLayout.BELOW, tvLocation.getId());
LinearLayout LL = new LinearLayout(getBaseContext());
LL.setOrientation(LinearLayout.VERTICAL);
for (int i=0;i< size;i++) {
tv[i] = new TextView(getBaseContext());
tv[i].setText(languageNames.get(i).toString());
tv[i].setPadding(50, 50, 0, 0);
tv[i].setTextColor(Color.parseColor("#000000"));
LL.addView(tv);
}
r1.addview(LL, p);
Try this code:
LinearLayout rl = (LinearLayout)findViewById(R.id.mainLayout);
TextView[] tv = new TextView[10];
for(int i=0; i<10; i++)
{
tv[i] = new TextView(getBaseContext());
tv[i].setText("TextView "+ i);
tv[i].setPadding(50, 50, 0, 0);
tv[i].setTextColor(Color.parseColor("#000000"));
rl.addView(tv[i]);
}
Hope this will help you
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.
