Hi i want to create a list of textview with each item clickable like in the image.
In your onClick or in the Event you want to add a TextView try this:
TextView textView = new TextView(Activity.this);
textView.setText();
textView.setTextColor();
textView.setTextSize();
textView.setOnClickListener();
Now suppose you have a horizontal LinearLayout then
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
//Set your margins here.
params.topMargin = 0;
params.rightMargin = 0;
params.leftMargin = 0;
params.bottomMargin = 0;
textView.setLayoutParams(params);
linearLayout.addView(textView);
Hope this helps.

I have the following:
Button[] buttons = new Button[forSale.size()];
TextView[] textViews = new TextView[forSale.size()];
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
for (int i = 0; i < forSale.size(); i++) {
rl = (RelativeLayout)findViewById(R.id.marketView);
textViews[i] = new TextView(this);
textViews[i].setText("\n" + forSale.get(i).getTradeGoodType()
+ "\t$"
+ forSale.get(i).getTradeGoodType().getBasePrice() +
"\n");
textViews[i].setId(i);
goodsForSaleText.append(textViews[i].getText());
buttons[i] = new Button(getApplicationContext());
buttons[i].setText("BUY");
// add the rule that places your button below your TextView object
params.addRule(RelativeLayout.BELOW, textViews[i].getId());
buttons[i].setLayoutParams(params);
rl.addView(buttons[i]);
}
My problem is that my the buttons are being added on top of each other at the top of the screen rather than one after the other below the TextViews.
Basically, it should look like:
TextView
Button
TextView
Button
TextView
Button
I need to dynamically add buttons for each number of TextViews I have (derived from a list). Can anyone help me out?
Use LinearLayout with vertical orientated instead of RelativeLayout. You will get automatically vertical position of objects
I'm having a linear layout in which I want to insert a checkbox on left and a button on its right.
Also, it should be in for loop so as to create many number of such combination in that single linear layout.
final LinearLayout LayoutRight = (LinearLayout) findViewById(R.id.linearlayoutbars_register);
LayoutRight.setOrientation(LinearLayout.VERTICAL);
LayoutRight.setWeightSum(1f);
final LinearLayout.LayoutParams pR1 = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.MATCH_PARENT);
pR1.weight = 0.3f;
final LinearLayout.LayoutParams pR2 = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.MATCH_PARENT);
pR2.weight = 0.7f;
for (int i = l; i <= lastCounter; i++) {
tick = new CheckBox(RegisterActivity.this);
tick.setId(10000 + l);
tick.setOnClickListener(tick_Click);
LayoutRight.addView(tick, pR1);
pdR = new Button(RegisterActivity.this);
pdR.setText(l + ". ");
pdR.setId(l);
pdR.setWidth(800);
pdR.setTextSize(17);
pdR.setGravity(Gravity.START);
pdR.setOnClickListener(pdRclass);
LayoutRight.addView(pdR, pR2);
l++;
}
I'm setting 1f as the setWeightSum; 0.3f and 0.7f and childs weight.
With this code I'm getting output as this
But I want my output exactly like this.
You need to set Layout orientation Like this LayoutRight.setOrientation(LinearLayout.HORIZONTAL);
not VERTICAL
LayoutRight.setOrientation(LinearLayout.HORIZONTAL)?
I'm not cool enough to comment so...
Android weight doc says the effected attribute needs to be set to 0dp so try this.
final LinearLayout.LayoutParams pR1 = new LinearLayout.LayoutParams(
0,
LinearLayout.LayoutParams.WRAP_CONTENT);
pR1.weight = 0.3f;
final LinearLayout.LayoutParams pR2 = new LinearLayout.LayoutParams(
0,
LinearLayout.LayoutParams.WRAP_CONTENT);
pR2.weight = 0.7f;
don't forget to keep your orientation horizontal!
I have a list of items and a relative layout. I want to add as many relative layouts as the no of items in list and textview in each on them.
My problem is, I am not able to position the textview in the centre of the layout.
Below in my code
for(int i = 0; i < Names.size(); i++)
{
textView = new TextView(this);
textView.setText(Names.get(i));
rt=new RelativeLayout(this);
rt.setBackgroundResource(R.drawable.mednamedash);
int curTextViewId = prevTextViewId + 1;
int curRLId = prevRLId + 1;
textView.setId(curTextViewId);
rt.setId(curRLId);
final RelativeLayout.LayoutParams params =
new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.BELOW, prevTextViewId);
rt.setLayoutParams(params);
//textView.setLayoutParams(params);
rt.addView(textView);
textView.setGravity(Gravity.CENTER);
prevTextViewId = curTextViewId;
prevRLId=curRLId;
noon.addView(rt, params);
}
Here rt is the dynamiclly created RelativeLayout and textView is the dynamically created TextView... noon is the RelativeLayout I am adding everything into.
Try this:
final RelativeLayout.LayoutParams tvParams =
new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
tvParams.addRule(RelativeLayout.CENTER_IN_PARENT);
rt.addView(textView, tvParams);
Try with textView.setGravity(Gravity.CENTER); before its addition to the rt (RelativeLayout)
I want to create a relative layout inside a linear layout dynamically.This relative layout contains a text view and button which are also created in dynamic method.The alignment of text view and button not work properly.The code which i have tried is given below.
final LinearLayout lab_linear = (LinearLayout) findViewById(R.id.contact_list_layout);
lab_linear.setOrientation(LinearLayout.VERTICAL);
for (int i = 0; i < Size_contact; i++)
{
RelativeLayout layout = new RelativeLayout(this);
RelativeLayout.LayoutParams lp = new
RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,RelativeLayout.LayoutParams.WRAP_CONTENT);
layout.setLayoutParams(lp);
final TextView Questions_value = new
android.widget.TextView(getApplicationContext());
Questions_value.setText(contact_name.get(i));
Questions_value.setTextSize(18);
Questions_value.setId(i);
layout.addView(Questions_value);
Button myButton = new Button(this);
myButton.setBackgroundResource(R.drawable.close);
myButton.setLayoutParams(new LayoutParams(20,20));
layout.addView(myButton);
lab_linear.addView(layout);
}
Try this..
Give layout parems for RelativeLayout individually to TextView and Button and also add addRule(RelativeLayout.ALIGN_PARENT_RIGHT); or addRule(RelativeLayout.ALIGN_PARENT_LEFT); for that views
Or add the below in for Button
lp1.addRule(RelativeLayout.RIGHT_OF, Questions_value.getId());
for (int i = 0; i < Size_contact; i++)
{
RelativeLayout layout = new RelativeLayout(this);
RelativeLayout.LayoutParams lp = new
RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
final TextView Questions_value = new
android.widget.TextView(getApplicationContext());
Questions_value.setText(contact_name.get(i));
Questions_value.setTextSize(18);
Questions_value.setId(i);
layout.addView(Questions_value,lp);
RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
lp1.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
//Or below remove above code and uncomment the below code
//lp1.addRule(RelativeLayout.RIGHT_OF, Questions_value.getId());
Button myButton = new Button(this);
myButton.setBackgroundResource(R.drawable.close);
myButton.setLayoutParams(new LayoutParams(20,20));
layout.addView(myButton,lp1);
lab_linear.addView(layout);
}
Might I suggest using LinearLayouts instead of RelativeLayouts in your loop? That way, you won't have the overlap problem.
RelativeLayout layout = (RelativeLayout)findViewById(R.id.rl);
for(int i = 1; i <= count; i++)
{
final TextView textViewUtente = new TextView(mContext);
final TextView textViewMessaggio = new TextView(mContext);
final TextView textViewData = new TextView(mContext);
textViewUtente.setText(sepUser[i]);
textViewMessaggio.setText(sepMessage[i]);
textViewData.setText(sepDate[i]);
int curTextViewIdUtente = 1000+i;
int curTextViewIdMessaggio = 2000+i;
int curTextViewIdData = 3000+i;
textViewUtente.setId(curTextViewIdUtente);
textViewMessaggio.setId(curTextViewIdMessaggio);
textViewData.setId(curTextViewIdData);
final RelativeLayout.LayoutParams params =
new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
params.topMargin= 100+i*150;
textViewUtente.setLayoutParams(params);
layout.addView(textViewUtente, params);
params.topMargin= 250+i*150;
textViewMessaggio.setLayoutParams(params);
layout.addView(textViewMessaggio, params);
params.topMargin= 100+i*150;
params.rightMargin=200;
textViewData.setLayoutParams(params);
layout.addView(textViewData, params);
}
I need to create 3 textview (that create the post on the blog from the user) every for loop like this:
Post 1:
TextViewUSer TextViewDate
TextViewMessage
Post 2:
TextViewUSer TextViewDate
TextViewMessage
I'm able to make one blog's post(a group of text view) above the other.
I just can position them, like this, from eachother. they stuck one above the other.
I also trued with addRules the .ABOVE and others but it's even worst cause they stuck all on the top left corner
You can add Rules to your textviews like this
tv1 = new TextView(this);
tv1.setId((int)System.currentTimeMillis());
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
lp.addRule(RelativeLayout.BELOW, recent.getId());
tv1.setText("Time: "+System.currentTimeMillis());
rr.addView(tv1, lp);
Egs.
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
lp.addRule(RelativeLayout.RIGHT_OF, tv1.getId());
lp.addRule(RelativeLayout.BELOW, someOtherView.getId())
lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT)
