You can try something like:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LinearLayout MainLinearObj = (LinearLayout) findViewById(R.id.abc);
for(int j=0;j<3;j++)
{
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(100,100);
llp.setMargins(10, 10, 10, 10);
llp.weight = 1;
LinearLayout.LayoutParams llp1 = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
LinearLayout newLinearLayout = new LinearLayout(this);
newLinearLayout.setOrientation(LinearLayout.VERTICAL);
newLinearLayout.setLayoutParams(llp1);
for(int i = 0; i < 3; i++)
{
LinearLayout ll = new LinearLayout(MainActivity.this);
ll.setOrientation(LinearLayout.HORIZONTAL);
ll.setBackgroundColor(Color.RED);
ll.setLayoutParams(new LinearLayout.LayoutParams(100,100));
ll.setId(i);
newLinearLayout.addView(ll,llp);
}
MainLinearObj.addView(newLinearLayout);
}
}
Edit:
Set the Main Linear Layout as Vertical orientation in XML and then use the following code:
LinearLayout MainLinearObj = (LinearLayout) findViewById(R.id.abc);
for(int j=0;j<10;j++)
{
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(100,100);
llp.setMargins(10, 10, 10, 10);
llp.weight = 1;
LinearLayout.LayoutParams llp1 = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
LinearLayout newLinearLayout = new LinearLayout(this);
newLinearLayout.setOrientation(LinearLayout.HORIZONTAL);
newLinearLayout.setLayoutParams(llp1);
for(int i = 0; i < 3; i++)
{
LinearLayout ll = new LinearLayout(MainActivity.this);
ll.setOrientation(LinearLayout.VERTICAL);
ll.setBackgroundColor(Color.RED);
ll.setLayoutParams(new LinearLayout.LayoutParams(100,100));
ll.setId(i);
newLinearLayout.addView(ll,llp);
}
MainLinearObj.addView(newLinearLayout);
}
Edit2
int no = Integer.parseInt(str);;
int count = 0;
int myvar = (no/3) +1;
for(int j=0;j<myvar;j++)
{
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(100,100);
llp.setMargins(10, 10, 10, 10);
llp.weight = 1;
LinearLayout.LayoutParams llp1 = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
LinearLayout newLinearLayout = new LinearLayout(this);
newLinearLayout.setOrientation(LinearLayout.HORIZONTAL);
newLinearLayout.setLayoutParams(llp1);
for(int i = 0; i < 3; i++)
{
LinearLayout ll = new LinearLayout(MainActivity.this);
ll.setOrientation(LinearLayout.VERTICAL);
ll.setBackgroundColor(Color.RED);
ll.setLayoutParams(new LinearLayout.LayoutParams(100,100));
ll.setId(i);
count++;
if(count<=no)
newLinearLayout.addView(ll,llp);
}
MainLinearObj.addView(newLinearLayout);
if(count==no) {
break;
}
}

Make Linear Layout not exit the screen

I'm fairly new to android and xml layouting. I've been trying to make an app, and already done with the programming bit. However i'm stuck on the finalisation of the layout. Really need a hand. My app should look like this:
I've divided the screen in 4 Linear Layouts as I have numbered in the picture as seen below:

The problem now is that, the second section is filled programmatically and it has a range of rows from 8 to 14. The same for the columns. Every block is a different button which I add with this code:
Lay= (LinearLayout)findViewById(R.id.Section2);
for (int row = 0; row < numberOfRows; row++)
{
LinearLayout Linearrow = new LinearLayout(this);
Linearrow.setOrientation(LinearLayout.HORIZONTAL);
for (int column = 0; column < numberOfColumns; column++)
{
View a = Chosen.blocks[row][column]; //This is a View the extend Button that has no layout properties defined
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT, 1.0f);
a.setLayoutParams(params);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
lp.weight = 1.0f;
Linearrow.addView(a, lp);
}
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
lp.weight = 1.0f;
Lay.addView(Linearrow, lp);
}
I have tried even using a TableLayout and assigning a small image as background so it could get resized with the following code:
TL =(TableLayout)fa.findViewById(R.id.Section2);
for (int i = 0; i < numberOfRows; i++)
{
TableRow tableRow = new TableRow(c);
for(int j = 0; j < numberOfColumns; j++)
{
String s = T[(i * 10) + j];
Block b = new Block(c, s);
//int w = Math.round(c.getResources().getDisplayMetrics().density * 20);
//int h = Math.round(c.getResources().getDisplayMetrics().density * 80);
//b.setLayoutParams(new TableRow.LayoutParams(w, h, 2.0f));
b.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT, 1f));
b.setBackgroundResource(R.drawable.g_3);
tableRow.addView(b);
tableRow.setLayoutParams(new android.widget.LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, 5f));
final Block fb = b;
}
TL.addView(tableRow);
}
When I run the app, I can see that unless I open it on a big screen phone, the content is not visible entirely(as if the height is set fixed manually of the layouts), and since it is not scroll-able, the content is not visible. How can I rearrange or modify the layout so it looks as in the picture above?

And in your java class where you add views dynamically, calculate the weights of children accordingly as given below
Lay= (LinearLayout)findViewById(R.id.Section2);
Lay.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
int totalWidth = Lay.getMeasuredWidth();
float rowWeight = 1 / numberOfRows;
int columnWidth = totalWidth / numberOfColumns;
for (int row = 0; row < numberOfRows; row++)
{
LinearLayout Linearrow = new LinearLayout(this);
Linearrow.setOrientation(LinearLayout.HORIZONTAL);
for (int column = 0; column < numberOfColumns; column++)
{
View a = Chosen.blocks[row][column]; //This is a View the extend Button that has no layout properties defined
// height is determined by row's layout weight
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(columnWidth,
LinearLayout.LayoutParams.MATCH_PARENT, 1.0f);
a.setLayoutParams(params);
Linearrow.addView(a);
}
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
lp.weight = rowWeight;
Lay.addView(Linearrow, lp);

I've not tested these, but just might work with few changes that you can figure out once you run this code.

Use
android:layout_weight
attribute to arrange in equal parts in linear layout.
See in the Link

It is better to use View inside ScrollView. Use the below code:-

I want to achieve the same output but programmatically

Try This
add LinearLayout into your xml
<LinearLayout
android:id="#+id/ll_main"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#android:color/white">
</LinearLayout>
and change in your Java file like this
LinearLayout ll_main = (LinearLayout) findViewById(R.id.ll_main);
for(int i= 0; i <5 ;i++) {
LinearLayout parent = new LinearLayout(Main.this);
LinearLayout.LayoutParams param= new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
param.weight = 1;
parent.setLayoutParams(param);
parent.setOrientation(LinearLayout.VERTICAL);
TextView tv = new TextView(Main.this);
tv.setText("T1");
TextView tv2 = new TextView(Main.this);
tv2.setText("T2");
parent.addView(tv);
parent.addView(tv2);
ll_main.addView(parent);
}

i just got my answer and its below
LinearLayout ll_main = (LinearLayout) findViewById(R.id.linear);
ll_main.setVisibility(View.VISIBLE);
int j = 5;
final LinearLayout[] linearlayout = new LinearLayout[j];
for (int i = 0; i < j; i++) {
LinearLayout parent = new LinearLayout(this);
LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
param.weight = 1;
parent.setLayoutParams(param);
parent.setOrientation(LinearLayout.VERTICAL);
TextView tv = new TextView(this);
tv.setText("T1");
TextView tv2 = new TextView(this);
tv2.setText("T2");
parent.addView(tv);
parent.addView(tv2);
linearlayout[i] = parent;
ll_main.addView(parent);
}
}
}

Dynamic UI - How to add 3 linearlayouts into a parent linearlayout

I'm having a little bit of trouble with creating a dynamic UI.
I can get it to work with just one LinearLayout but I have no idea how to add more.
This is what I have now, it's one LinearLayout with 3 buttons.
Here is the code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main);
maakLayout();
}
private void maakLayout() {
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
LayoutParams layoutParams = new LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT);
linearLayout.setLayoutParams(layoutParams);
setContentView(linearLayout);
for (int i = 0; i < 3; i++) {
Button button = new Button(this);
button.setText("Test");
button.setTag(i);
button.setBackgroundResource(R.drawable.border_red);
LayoutParams layoutTextParams = new LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
// LayoutParams layoutImageParams =
// new LayoutParams(100,100);
layoutTextParams.topMargin = 5;
layoutTextParams.leftMargin = 5;
layoutTextParams.rightMargin = 5;
button.setLayoutParams(layoutTextParams);
linearLayout.addView(button);
}
}
What I need is the following:
And the static XML code for this is the following:
<LinearLayout 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:orientation="horizontal"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.test.MainActivity" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginRight="5dp"
android:orientation="vertical" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/border_red"
android:text="Test" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/border_red"
android:text="Test" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/border_red"
android:text="Test" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="144dp"
android:layout_marginRight="5dp"
android:orientation="vertical" >
<Button
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#drawable/border_blue"
android:text="Test" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/border_red"
android:text="Test" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/border_red"
android:text="Test" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/border_red"
android:text="Test" />
</LinearLayout>
</LinearLayout>
Once I know how to add other linearlayouts I'm good I think, thank you for your help.

LinearLayout is itself a subclass of View, so you can add it as a child to other LinearLayouts.
Like so:
LinearLayout horizontalLayout = new LinearLayout(this);
horizontalLayout.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout verticalLayout1 = new LinearLayout(this);
verticalLayout1.setOrientation(LinearLayout.VERTICAL);
LinearLayout verticalLayout2 = new LinearLayout(this);
verticalLayout2.setOrientation(LinearLayout.VERTICAL);
horizontalLayout.addView(verticalLayout1);
horizontalLayout.addView(verticalLayout2);
Just populate your first and third vertical layout with buttons as you do in your loop.
Hope this helps.

TableLayout inside ListView

There is a page in my android application which has a slide out menu and some data that needs to be displayed in the main screen. The slide out menu has the required menu options.
the main page is in ListView format. I want a TableLayout format layout inside this ListView.
The problem is when i change the layout to TableLayout, it messes up with my java activity file.
I want to display data extracted from an external source on the main screen of this page in table format.
The XML and Java Activity files are enclosed.
Thanks in advance.
