I have a layout where I put i rows dynamically in a tablelayout that is inside a scrollview. Everything is working smoothly except that I don't can get the checkbox text to wordwrap (See xml below). The text is also set at runtime. I have searched the internet and has made a lot of trying to set different properties with no luck so far.
Is this task possible to achieve?
<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="15dip">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<CheckBox
android:id="#+id/bes_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="" />
<EditText
android:id="#+id/bes_kommentar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/bes_checkbox" />
</RelativeLayout>
</TableRow>
CheckBox extends TextView, so I assume you can wrap its text like they solve the issue in this post :
Android TextView Text not getting wrapped
If you cannot get it to work like that, you can maybe also try, using match_parent in the checkbox.
<CheckBox
android:id="#+id/bes_checkbox"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="" />
hope it helps.
use table row inside the Linear layout instead of table layout..
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="15dip" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<CheckBox
android:id="#+id/bes_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<EditText
android:id="#+id/bes_kommentar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/bes_checkbox" />
</RelativeLayout>
</TableRow>
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="15dip" >
<RelativeLayout
android:layout_width="match_parent"

<CheckBox
android:id="#+id/bes_checkbox"
android:layout_width="wrap_content"

/>
<EditText
android:id="#+id/bes_kommentar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/bes_checkbox" />
</RelativeLayout>
</TableRow>
</LinearLayout>
I have made dynamic layouts with checkboxes in the past and used this approach:
// Create new view to add layout to
sv = new ScrollView(this);
// Create new layout to add check boxes to
ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
// Add layout to view
sv.addView(ll);
// Create 6 check boxes
int itemSize = 6;
for(int j=0; j<itemSize; j++){
CheckBox cb = new CheckBox(this);
cb.setText("number " + j);
ll.addView(cb);
}
// Finalize view
this.setContentView(sv);
Is this what you are looking for?

I have a ScrollView that I am trying to populate dynamically. Here is the XML that contains the ScrollView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#f6f5f5" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#40ff0000"
android:paddingBottom="70dp"
android:paddingTop="20dp"
android:paddingLeft="20dp"
android:paddingRight="20dp">
<LinearLayout
android:id="#+id/option_list_container"
android:background="#40ffff00"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:background="#292929"
android:paddingBottom="5dp"
android:paddingLeft="15dp"
android:paddingTop="5dp"
android:text="Stap 3/5"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#color/white" />
</LinearLayout>
</ScrollView>
And here is the XML for the element I'm inserting in the ScrollvVew:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<np.custom.FontIcon
android:id="#+id/option_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/calendar_circleround"
android:textSize="40sp"
android:gravity="center"
android:text="#string/planit_selection_empty_circle"
android:textColor="#292929" />
<TextView
android:id="#+id/option_text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:layout_marginLeft="10dp"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
This is the code I use to populate the scrollview:
ArrayList<String> g = new ArrayList<String>();
g.add("Fix a Bug");
g.add("Buy a new PC");
g.add("Make Coffee");
g.add("Take a Break");
g.add("Don't do that");
g.add("Throw your hands in the air like you just don't care!");
LinearLayout optionListLayout = (LinearLayout) rootView.findViewById(R.id.option_list_container);
LayoutInflater inflater = LayoutInflater.from(getActivity());
for(String p:g){
View v = inflater.inflate(R.layout.planit_option_item, null);
TextView optText = (TextView) v.findViewById(R.id.option_text);
optText.setText(p);
optionListLayout.addView(v);
}
This all works almost fine, except that the sizes of the ScrollView and the LinearLayout it contains do not come out as I expected. This a screenshot of that it looks like on a device, which shows text being cut out when it goes to a second line:
So how can I make sure the linear layout re-sizes to accommodate children views of different heights?
Your issue isn't the ScrollView not accommodating new children. The problem is that the text, when it spans more than one line, is being clipped due to layout parameters in R.layout.planit_option_item. Try changing the TextView of ID #+id/option_text so that its height is wrap_content.
Change your TextView for the ScrollView element to accommodate two lines:
...
<TextView
android:id="#+id/option_text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:layout_marginLeft="10dp"
android:maxLines="2"
android:singleLine="false"
android:textAppearance="?android:attr/textAppearanceMedium" />
...
This is not an issue with ScrollView, it's an issue with the specifications of the element you are inserting into the ScrollView. If you expect there may be more than 2 lines of text in some cases set maxLines = X where X is the maximum number of lines you expect.
Please let me know if this does not work and I would be happy to help further.
I realize there many related problems, but I'm looking for this specific answer. The below code is my XML for my mainactivity in an app. Now my question. I would like to be able to alter the contents of the horizontal view, dynamically. This will involve clearing it of Views as well as adding new ones. How exactly do I go about doing this, as well as accessing the Linear Layout within it, when I tried to assign an ID to the Linear Layout I was given an error saying it could not accept a id of type string.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:id="#+id/txtClassification"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="Classification:<>"
android:textAppearance="?android:attr/textAppearanceLarge"
tools:ignore="HardcodedText" />
<Spinner
android:id="#+id/spinGoto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginBottom="56dp" />
<Button
android:id="#+id/btnBack"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_alignParentLeft="true"
android:text="Select"
tools:ignore="HardcodedText" />
<HorizontalScrollView
android:id="#+id/gallery"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/txtClassification"
android:layout_alignRight="#+id/spinGoto"
android:layout_below="#+id/txtClassification" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
</LinearLayout>
</HorizontalScrollView>
<ImageView
android:id="#+id/myImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</RelativeLayout>
All help is greatly appreciated!
You will have to work with the LinearLayout because a HorizontalScrollView can only have one direct child.
<HorizontalScrollView
android:id="#+id/gallery"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/txtClassification" >
<LinearLayout
android:id="#+id/yourLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
</HorizontalScrollView>
Then you access it programmatically to add or remove views
public void addView(View v) {
LinearLayout yourLayout = (LinearLayout) findViewById(R.id.yourLayout);
yourLayout.addView(v);
}
public void clearLayout() {
LinearLayout yourLayout = (LinearLayout) findViewById(R.id.yourLayout);
yourLayout.removeAllViews();
}
public void removeView(View v) {
LinearLayout yourLayout = (LinearLayout) findViewById(R.id.yourLayout);
yourLayout.removeView(v);
}
hope this helps
The id has a predifined format. Enter the name you want after the "#+id/" syntax. Example android:id="#+id/layout".
Then in code get the LinearLayoutinside of the HorizontalScrollView:
LinearLayout layout = findViewById(R.id.layout);
To add a View to layout call the adView() of your layout. Example:
//add 5 buttons
for (int i = 1; i <= 5 ; i++){
Button btn = new Button(this);
btn.setId(i);
btn.setText(i+"");
layout.addView(btn);
}
To remove a View from the layout call removeView()
//remove button nr. 3
Button btn3 = layout.findViewById(3);
layout.removeView(btn3);
The HorizontalScrollView takes care of everything, you just have to populate and organize the elements inside the nested LinearLayout.
Good luck!
I have below layout i.e 1 spinner and a linear layout containing some edit box's and spinner's.this layout maps/represent to an object (Lets call it X).
The main spinner will be having n number of entries and each entry maps to the layout object (X).So, In all i will need to have n number of layouts
I want to allow user to fill only 1 object at a time ,so, I would keep only 1 layout visible.In order to solve this , One way would be having n number of layouts in .xml and playing with the visibility in onitemselected of the listener.Is there any other better/optiomized way of solving this.
How can i make this dynamic i.e if i dont know the value of n initially ?

try this, put that LinearLayout in another xml and call that xml as many times you want inside loop.
sample xml, name attrib_row.xml
<?xml version="1.0" encoding="utf-8"?>
<Linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/lable"
android:layout_width="150dip"
android:layout_column="0"
android:padding="3dip"
android:textColor="#000033" />
</Linearlayout>
code to call that in loop
Linearlayout row11 = (Linearlayout) LayoutInflater.from(this).inflate(
R.layout.attrib_row, null);
((TextView) row11.findViewById(R.id.lable)).setText("example");
I'm new to android application development. I'm trying to create a calculator application, and I got 2 questions to ask.
1.
How can I create a new row in LinearLayout?
It's currently looking like this:
[textview][textview][button]
And I want it to look like this:
[textview][textview]
[button]
This is my xml code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<TextView
android:id="#+id/number1"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="#string/number1" />
<TextView
android:id="#+id/number2"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="#string/number2" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_calculate" />
2. How can I process the sum of "number1" and "number2" Textviews and display it on the Main Activity (where the TextViews are)?
Linear layout can be horizontal or vertical, if you need rows and columns you need to work with relative layout or just add more then one linear layout such as..
TextView txtvar = (TextView) findViewById(R.id.textViewIdFromXml);
txtvar.setText("blah");
this how you connect to textview element whit id textViewIdFromXml and set blah for text
Nested linear layouts.
For example (pseudo xml):
<Linear Layout : Vertical>
<Linear Layout : Horizontal>
<TextView />
<TextView />
</Linear Layout>
<Button />
</Linear Layout>
Edit: I tried the following in Eclipse and for me it does what I think you ask (though it doesn't look fancy):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
</LinearLayout>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
1st Ans: create a Vertical Linear Layout & use a Horinzental one nested in the Vertical one. But I prefer relative layout.
2ns Ans: use onClickListener() for the buttons. & under every onClickListener() change the text of Number display textbox using setText(). but on = button's onClickListener() use the value of Number display textbox using getText() and use it for + - or in * /
I want to create a multirow Button list. Something like this :
but I want to do it dynamically(in code). Is there a way to tell layout to do this automatically? Or i have to do this myself usingRelativeLayout.LayoutParams. I can do this by code but I should control so many things and I was wondering if there is another easier way to do this. For example tell layout to add elements in the next row when the current one is full!
You could also do this with LinearLayout and make all the buttons the same size using weight.
As for your question:
i can do this by code but i should control so many things and i was
wondering if there is another easier way to do this. for example tell
layout to add elements in the next row when the current one is full!
This is potentially possible if you measure the screen width and height and use the Functions in in the View class to figure out the specifics of that particular view and its children.
Alternative
But as mentioned in the comments, there are other views that you can use to solve your problem like GridView.
You can also use a table layout ,
Create first row of tabllayout in xml like this
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="wrap_content"
>

android:id="#+id/goBack"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="6dp"
android:layout_marginTop="12dp"
/>

I created this xml for four three texts and on button in a single row
refer to the table in onCreate
TableLayout extendeedTable = (TableLayout)findViewById(R.id.data_table);
add rows like
while (extendeedTable.getChildCount() > 1)
{
// while there are at least two rows in the table widget, delete
// the second row.
extendeedTable.removeViewAt(1);
}
// collect the current row information from the database and
// store it in a two dimensional ArrayList
// iterate the ArrayList, create new rows each time and add them
// to the table widget.
// Here value is the number of rows you want in table
for (int position=0; position < value ; position++)
{
TableRow tableRow= new TableRow(this);
tableRow.setBackgroundDrawable(null);
// ArrayList<Object> row = data.get(position);

for this i took help from here
http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/7/
and
its xml
http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/6/
after some more google search i finally found the best way to do this. it's so clean and simple, using Adapters and grids.
thanks for all the answers
here is a Tutorial: Creating a Custom Adapter for Gridview(ButtonAdapter)
