Add a button within a ScrollView - android

I need some help I have a scrollview that shows some question with radio buttons and I want to add a button when the user reaches the last question and I want this button to be available only after the user has selected an answer to all the questions.
This is my code so far but it is not displaying anything. I can display the questions without the button but I want to display the button too.
String countryName[] = { "India", "Pakistan", "China", "Nepal",
"Bangladesh" };
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_quiz);
LinearLayout mLinearLayout = (LinearLayout) findViewById(R.id.linear1);
for (int k = 1; k <= 10; k++)
{
//create text button
TextView title = new TextView(this);
title.setText("Question Number:" + k);
title.setTextColor(Color.BLUE);
mLinearLayout.addView(title);
// create radio button
final RadioButton[] rb = new RadioButton[5];
RadioGroup rg = new RadioGroup(this);
rg.setOrientation(RadioGroup.VERTICAL);
for (int i = 0; i < 5; i++)
{
rb[i] = new RadioButton(this);
rg.addView(rb[i]);
rb[i].setText(countryName[i]);
}
mLinearLayout.addView(rg);}
ScrollView scroll = new ScrollView(this);
Button btn = new Button(this);
ViewGroup.LayoutParams blp = new ViewGroup.LayoutParams(
LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);
btn.setLayoutParams(blp);
btn.setText("Click Me");
mLinearLayout.addView(scroll);
mLinearLayout.addView(btn);
setContentView(mLinearLayout);
}
The XML file:
<!--?xml version="1.0" encoding="utf-8"?-->
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:id="#+id/buttons"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center"
android:layout_alignParentBottom="true">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignRight="#+id/textView3"
android:text="Continue" />
</LinearLayout>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/linear1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</ScrollView>
</RelativeLayout>

mLinearLayout.addView(btn);
scroll.addView(mLinearLayout);
setContentView(scroll);

You should place your LinearLayout inside the ScrollView, because ScrollView is a container and its children are scrollable. Also, set the ScrollView as the activity's content view and define its layout params.
ScrollView scrollView = new ScrollView(this);
scrollView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));
scroll.addView(mLinearLayout);
setContentView(scroll);

Hi I have found the right way to do it! The easiest way is to fix the XML file and add a LinearLayout within the LinearLayout and put the questions within the inner LinearLayout and the button in the outside LinearLayout.
Here is the trick:
<!--?xml version="1.0" encoding="utf-8"?-->
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/linear1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="2.87"
android:orientation="vertical" >
</LinearLayout>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="2.87"
android:text="Button" />
</LinearLayout>
</ScrollView>

Setting layout weight to dynamically added view is not working in Android

I am developing an Android App. In my app, I am adding view dynamically and setting its weight in code as well. But it is not working.
This is my XML for container of dynamic views:
<ScrollView>
.
.
.
<LinearLayout
android:orientation="vertical"
android:id="#+id/id_related_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"></LinearLayout>
.
.
.
</ScrollView>
This is how I am adding controls dynamically to it.
private void addRelatedItemViews(final ArrayList<Item> relatedItems)
{
LinearLayout subContainer= new LinearLayout(this);
LinearLayout.LayoutParams initialParam = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
subContainer.setLayoutParams(initialParam);
relatedItemsContainer.addView(subContainer);
for(int i=0;i<relatedItems.size();i++)
{
if(i>0 && i%2==0)
{
//initialize sub container
subContainer = new LinearLayout(this);
LinearLayout.LayoutParams subContainerParam = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
subContainer.setLayoutParams(subContainerParam);
relatedItemsContainer.addView(subContainer);
}
final int index = i;
View view = layoutInflater.inflate(R.layout.realated_item_view,null);
ImageView imageView = (ImageView)view.findViewById(R.id.iv_related_item_image);
TextView tvName = (TextView)view.findViewById(R.id.tv_related_item_name);
TextView tvPrice = (TextView)view.findViewById(R.id.tv_related_item_price);
TextView tvLikeCount = (TextView)view.findViewById(R.id.tv_related_item_like_count);
Picasso.with(getBaseContext()).load(relatedItems.get(i).getMediumImageUrl()).into(imageView);
tvName.setText(relatedItems.get(i).getName());
tvPrice.setText(CommonHelper.formatCurrency(relatedItems.get(i).getPrice()));
tvLikeCount.setText(CommonHelper.formatLikeCount(relatedItems.get(i).getLikeCount()) + " like");
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
openItemActivity(relatedItems.get(index).getId());
}
});
LinearLayout itemContainer = new LinearLayout(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT,1);
itemContainer.setLayoutParams(params);
itemContainer.addView(view);
subContainer.addView(itemContainer);
}
}
This is my realated_item_view.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="wrap_content"
android:layout_weight="1"
android:padding="3dp"
android:layout_height="wrap_content">
<LinearLayout
android:background="#drawable/item_bg"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/iv_related_item_image"
android:scaleType="centerCrop"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<LinearLayout
android:padding="5dp"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:textStyle="bold"
android:textSize="17dp"
android:id="#+id/tv_related_item_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_marginTop="3dp"
android:textSize="13dp"
android:id="#+id/tv_related_item_price"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_marginTop="3dp"
android:textSize="10dp"
android:id="#+id/tv_related_item_like_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
But it is not settings its weight properly. Actually, each row has two column and each column must be half of screen width. But it is not working.
This is the screenshot:
As you can see, it not taking screen half by half. How can I fix it?
Try this below in your realated_item_view.xml (wrap_content to fill_parent)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_weight="1"
android:padding="3dp"
And change your Java code:
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT,1);
itemContainer.setLayoutParams(params);
itemContainer.addView(view);
subContainer.addView(itemContainer);
But maybe your image will be stretched by the width. But it will fill half of the width as you want.
UPDATE:
I dont know why you tried failed with above solution. So I write a small demo for referencing. It uses ScrollView as you want. But I strongly recommend you should use GridView instead for better perfomance!!!
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test_layout);
LinearLayout containerLayout = (LinearLayout) findViewById(R.id.container_layout);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
LayoutInflater inflater = getLayoutInflater();
for (int i = 0; i < 4; i ++){
LinearLayout subLayout = new LinearLayout(this);
subLayout.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout.LayoutParams subParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT, 1);
for (int j = 0; j < 3; j ++){
View v = inflater.inflate(R.layout.test_item_layout, null, false);
if (j == 1){
ImageView imageView = (ImageView) v.findViewById(R.id.imageView);
imageView.setImageResource(R.drawable.icon);
}
subLayout.addView(v, subParams);
}
containerLayout.addView(subLayout, params);
}
}
test_item_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imageView"
android:src="#mipmap/ic_launcher"
android:scaleType="centerCrop"
android:layout_width="match_parent"
android:layout_height="100dip" />
<TextView
android:text="Test label"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
test_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/container_layout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>
</ScrollView>
</LinearLayout>
Screenshot:
Instead of ViewGroup.LayoutParams try it with LinearLayout.LayoutParams and also set layout width to 0
LinearLayout itemContainer = new LinearLayout(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(0, LinearLayout.LayoutParams.WRAP_CONTENT,1);
itemContainer.setLayoutParams(params);
It might work.
try this
use straggerdgridlayout manager
RecyclerView recyclerView = (RecyclerView)findViewById(R.id.recycler_view);
recyclerView.setHasFixedSize(true);
gaggeredGridLayoutManager = new StaggeredGridLayoutManager(column, 1);
recyclerView.setLayoutManager(gaggeredGridLayoutManager);
column replaces your requirement of column

How to update the textview dynamically created textview in childlayout?

LinearLayout lay1 = (LinearLayout) findViewById(R.id.lay1);
for(int i=0;i<list1.size();i++) {
View child = lay1.getChildAt(i);
LinearLayout lay3 = (LinearLayout) child.findViewById(R.id.lay3);
for (j = 0; j <list2.size(); j++) {
View child1 = lay3.getChildAt(j);
// View hiddenInfo11 = getActivity().getLayoutInflater().inflate(R.layout.add_inner_item, lay3 , false);
final TextView name = (TextView) child1.findViewById(R.id.name);
name.setText("new");
}
}
XML Layout:
<LinearLayout

Added View Dynamically using the following method.
for(int i=0;i<list.size();i++) {
View hiddenInfo = getActivity().getLayoutInflater().inflate(R.layout.add_item, lay, false);
LinearLayout lay3 = (LinearLayout) hiddenInfo.findViewById(R.id.lay3);
lay1.addView(hiddenInfo);
for (j = 0; j < list2.size(); j++) {
View hiddenInfo1 = getActivity().getLayoutInflater().inflate(R.layout.add_inner_item, lay3, false);
final TextView name = (TextView) hiddenInfo1.findViewById(R.id.name);
name.setText(list2.get(j).get("Name"));
lay3.addView(hiddenInfo1);
}
I have one Layout with creating dynamically and I want to update the child textview from outside of the button click view.I have tried this code.But nothing is changed.Can anyone give suggestion to this sample.
You are looking for "lay2" inside the "lay1" container. According to your XML layout, they are not nested, so you won't be able to find it this way. Change it to this:
LinearLayout lay2 = (LinearLayout) findViewById(R.id.lay2);
You should get the actual lay2 container. I'm not sure whether the text views are there though since I have seen your code for the views' creation.
EDIT:
I've not specified a parent - you should use the Activity for this. Something like:
LinearLayout lay2 = (LinearLayout) MyActivity.this.findViewById(R.id.lay2);

How can I programatically create a ScrollView with RelativeLayout boxes like this?

I am trying to create an Activity with a ScrollView in it. In the ScrollView will be "boxes" (sort of like a button) that is just a bit smaller than the width of the parent view and spaced slightly apart vertically. Because the boxes will have a couple different size text in a couple areas on them, I think I need to make the out of RelativeLayouts. (I would post a picture but can't with my reputation point so hopefully this makes sense).
I tried create an XML for the activity and than programatically adding the relativeviews. I got it to work, sort of, but am having trouble with the box spacing.
My test XML looks like this...
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android">
<!-- scrolling section -->
<ScrollView
android:layout_width="fill_parent"
android:paddingTop="5dp"
android:layout_height="0dp"
android:layout_weight="1.30"
>
<LinearLayout
android:id="#+id/llScroll"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
</LinearLayout>
</ScrollView>
</LinearLayout>
My Activity looks like this...
public class TestActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
LinearLayout llAccts=(LinearLayout)findViewById(R.id.llScroll);
for (int i=1;i<20;i++) {
RelativeLayout rlView = new RelativeLayout(this);
rlView.setBackgroundColor(Color.BLUE);
TextView test=new TextView(this);
test.setText("Test #"+i);
test.setTextColor(Color.WHITE);
rlView.addView(test);
llAccts.addView(rlView,new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
}
}
}
I get the scrollable section, no problem. Problem is my blue "boxes" appear to be touching one another and I can't figure out how to make them look like buttons with padding left and right and between them. I tried
rlView.setPadding(20,20,20,20);
right after the setBackground color. All that appears to do is pad the text... not the RelativeViews.
Any suggestions no how to get this to work?
Thanks

NEW INFORMATION:
Here is some additional information after following some suggestions and trial an error. I was also able to post a pic for easier reference.

What I am trying to achieve, programmatically, is something that looks like this.
I achieved this example using the straight XML which looks like this...
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"

/>
</RelativeLayout>
</LinearLayout>
</ScrollView>
</LinearLayout>
I took this apart and created an XML file and and activity that will programmatically create the middle groups.
The modified XML (activity_main2) looks like this...
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android">
<!-- header: non-scrolling -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="UPDATE ALL"
android:id="#+id/btnUpdate" />
</RelativeLayout>
<!-- scrolling bottom pane -->
<ScrollView
android:layout_width="fill_parent"
android:paddingTop="5dp"
android:layout_height="0dp"
android:layout_weight="1.30"
>
<LinearLayout
android:id="#+id/llGroups"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
</LinearLayout>
</ScrollView>
</LinearLayout>
I started rewriting my activity code to test some of the suggestions. It currently looks like this...
public class Main2Activity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
LinearLayout llGroups=(LinearLayout)findViewById(R.id.llGroups);
for (int i=1;i<20;i++) {
RelativeLayout rlView = new RelativeLayout(this);
rlView.setBackgroundColor(Color.BLUE);
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
rlp.setMargins(10,10,10,0);
TextView test=new TextView(this);
test.setText("Test #"+i);
test.setTextColor(Color.WHITE);
rlView.addView(test);
// other textviews will go here
llGroups.addView(rlView,rlp);
}
}
}
This compiles and runs, but the setMargins is not working. My screen has the "UPDATE ALL" button at the top like it should and (19) "Text #" with a blue background, but they are full width and touching one another so it is a solid blue background.
I am getting close, but not sure how to get the margins to set correctly for the rlView relativeview (not the textviews).
Hopefully this helps explain what I am seeing now..
SOLUTION
After suggestions, and some trial and error... here is what I had to do to achieve the desired layout in case someone else is interested.
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams tvp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams tvp2 = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
LinearLayout mTvContainer = (LinearLayout) findViewById(R.id.llAccts);
for (int i = 0; i < 20; i++) {
LinearLayout ll = new LinearLayout(this);
ll.setBackgroundColor(Color.BLUE);
RelativeLayout rl = new RelativeLayout(this);
TextView tv = new TextView(this);
tv.setTextColor(Color.WHITE);
tv.setPadding(5, 5, 5, 5);
tv.setText("Test #" + i);
tvp.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
TextView tv2 = new TextView(this);
tv2.setTextColor(Color.WHITE);
tv2.setPadding(5, 5, 5, 5);
tv2.setText(String.valueOf(i));
tv2.setTextSize(30);
tvp2.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
rl.addView(tv, tvp);
rl.addView(tv2,tvp2);
ll.addView(rl);
llp.setMargins(32,16,32,16);
mTvContainer.addView(ll,llp);
}
}
For each entry in the FOR, I had to use a LINEARLAYOUT to be able to set the margins properly, and in that LINEARLAYOUT I had to use a RELATIVELAYOUT to use the addRules to get the proper positioning of the TextViews.
If there is an easier way, let me know. Thanks for everyones help!!
You are using too much nested layouts needed, here is stripped version.
xml:
<ScrollView 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"
tools:context=".MainActivity">
<LinearLayout
android:id="#+id/ll_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" />
</ScrollView>
Activity code:
mTvContainer = (LinearLayout) findViewById(R.id.ll_main);
int p = (int) getResources().getDimension(R.dimen.activity_horizontal_margin);
for (int i = 0; i < 20; i++) {
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
TextView tv = new TextView(this);
tv.setBackgroundColor(Color.BLUE);
tv.setTextColor(Color.WHITE);
tv.setPadding(p, p / 2, p, p / 2);
tv.setText("TextView " + i);
TextView tv2 = new TextView(this);
tv2.setBackgroundColor(Color.RED);
tv2.setTextColor(Color.WHITE);
tv2.setPadding(p, p / 2, p, p / 2);
tv2.setText("TextView " + i);
ll.addView(tv);
ll.addView(tv2);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(p, p / 2, p, p / 2);
mTvContainer.addView(ll, params);
}

How to dispaly result list into TableLayout row in android?

I have a little bit problem that displaying list data to TextView in Android. My scenario is I have a TableLayout with Default One TableRow. Inside table row, I has been created new LinearLayout. Then, Four TextView created inside LinearLayout. I adding some default value to this textview. My default value is

Actually, I want to create dynamically TableRow, LinearLayout and TextView. Then, I put the list result to add these. The list result come from sqlite db. But, I can't get what I want. Here my code for looping the list and display the result. But, I got my some default value. Please pointing to me how can I get this. Thanks.
Here snippet for display list.
public void displayHistory(){
List<IspHistoryListObject> historyList = sqlaccess.getAllItems();
TableLayout showRow = (TableLayout) findViewById(R.id.history_table);
int count = 0;
for(IspHistoryListObject hl : historyList) {
count++;
TableRow tr = new TableRow(this);
LinearLayout ll = new LinearLayout(this);
ll.setLayoutParams(new LinearLayout.LayoutParams(50,30));
TextView tv_sync_no = new TextView(this);
TextView tv_sync_date = new TextView(this);
TextView tv_sync_orderid = new TextView(this);
TextView tv_sync_qty = new TextView(this);
tv_sync_no.setText(String.valueOf(count));
tv_sync_date.setText(hl.getSyncDate().substring(0,10));
tv_sync_orderid.setText(hl.getSyncOrderIdRef());
tv_sync_qty.setText(String.valueOf(hl.getQty()));
ll.addView(tv_sync_no);
ll.addView(tv_sync_date);
ll.addView(tv_sync_orderid);
ll.addView(tv_sync_qty);
tr.addView(ll);
showRow.addView(tr);
}
}
try this way here I gave sample or demo code you have to modify as per your requirement and still have problem let me know
main layout
1. table.xml
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tableLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp"
android:orientation="vertical">
</TableLayout>
table row layout
2. table_item.xml
<?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:orientation="horizontal">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="#+id/history_display_no"
android:layout_weight="0.25"
android:gravity="center"/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:id="#+id/history_display_date"
android:layout_weight="0.25"
android:gravity="center"/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:id="#+id/history_display_orderid"
android:layout_weight="0.25"
android:gravity="center"/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:id="#+id/history_display_quantity"
android:layout_weight="0.25"
android:gravity="center"/>
</TableRow>
activity class
3. Activity
public class MyActivity extends Activity {
private TableLayout tableLayout;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.table);
tableLayout=(TableLayout)findViewById(R.id.tableLayout);
for (int i=0;i<5;i++){
View tableRow = LayoutInflater.from(this).inflate(R.layout.table_item,null,false);
TextView history_display_no = (TextView) tableRow.findViewById(R.id.history_display_no);
TextView history_display_date = (TextView) tableRow.findViewById(R.id.history_display_date);
TextView history_display_orderid = (TextView) tableRow.findViewById(R.id.history_display_orderid);
TextView history_display_quantity = (TextView) tableRow.findViewById(R.id.history_display_quantity);
history_display_no.setText(""+(i+1));
history_display_date.setText("2014-02-05");
history_display_orderid.setText("S0"+(i+1));
history_display_quantity.setText(""+(20+(i+1)));
tableLayout.addView(tableRow);
}
}
}
check out context hierachy
for(IspHistoryListObject hl : historyList) {
count++;
TableRow tr = new TableRow(showRow.getContext());
LinearLayout ll = new LinearLayout(tr.getContext());
ll.setLayoutParams(new LinearLayout.LayoutParams(50,30));
TextView tv_sync_no = new TextView(ll.getContext());
TextView tv_sync_date = new TextView(ll.getContext());
TextView tv_sync_orderid = new TextView(ll.getContext());
TextView tv_sync_qty = new TextView(ll.getContext());
tv_sync_no.setText(String.valueOf(count));
tv_sync_date.setText(hl.getSyncDate().substring(0,10));
tv_sync_orderid.setText(hl.getSyncOrderIdRef());
tv_sync_qty.setText(String.valueOf(hl.getQty()));
ll.addView(tv_sync_no);
ll.addView(tv_sync_date);
ll.addView(tv_sync_orderid);
ll.addView(tv_sync_qty);
tr.addView(ll);
showRow.addView(tr);
}
With listview you can easily do this:
ActivityMain.java
ListView lst = (ListView) findViewById(R.id.listView);
View header = getLayoutInflater().inflate(R.layout.list_header, null);
lst.addHeaderView(header);
lst.setAdapter(new CustomerListAdapter(this,4));
list_header.xml is header layout

button below other button programmatically android

i have in xml tis code:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:id="#+id/examp1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="#+id/examp2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/examp1" />
</RelativeLayout>
I want to create these buttons programmatically and i use:
RelativeLayout mainLayout;
mainLayout = (RelativeLayout) findViewById(R.id.mainLayout);
for (int i=0; i<1; i++)
{
Button new_button = new Button(this);
new_button.setText("blabla");
new_button.setId(i);
new_button.setLayoutParams(new LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
mainLayout.addView(new_button);
}
How can I translate this command android:layout_below="#id/examp1" programmatically?
Use RelativeLayout.LayoutParams. Use addRule(), for your example use it with RelativeLayout.BELOW and the id (R.id.examp1)
