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
1, 2014-02-05, S02, 20
Here my code snippet for above scenari0.
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#color/sync_history_table_color"
android:id="#+id/history_table"
android:orientation="vertical"
>
<TableRow
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:paddingTop="1dp"
android:id="#+id/row_start">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="30dp" android:id="#+id/row_linear" android:layout_weight="1"
android:background="#color/isp_home_color">
<TextView android:layout_width="0dp" android:layout_height="match_parent" android:text="#string/sync_default_no"
android:id="#+id/history_display_no" android:layout_weight="0.165"
android:gravity="center_vertical|left" android:paddingLeft="10dp"
android:textColor="#color/sync_history_text_color"/>
<TextView android:layout_width="0dp"
android:layout_height="match_parent"
android:text="#string/sync_default_date"
android:id="#+id/history_display_date"
android:layout_weight="0.5"
android:layout_gravity="center"
android:gravity="center"
android:textColor="#color/sync_history_text_color"/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:text="#string/sync_default_order"
android:id="#+id/history_display_orderid"
android:layout_weight="0.5"
android:layout_gravity="center"
android:gravity="center"
android:textColor="#color/sync_history_text_color"/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:text="#string/sync_default_qty"
android:id="#+id/history_display_quantity" android:layout_weight="0.5" android:layout_gravity="center"
android:gravity="center"
android:textColor="#color/sync_history_text_color"/>
</LinearLayout>
</TableRow>
</TableLayout>
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

I have two layouts, i inflate one layout into another and want to display this inflated layout including textview as many times as condition is true . I set the textview value as value of i and also set the layout top margin. but it displaying value of i in one row only and rest are blank,also its setMargin() also not working.Below is what i have done yet.
public void displayRows(){
int n= 6;
for(int i=0;i< n;i++){
LinearLayout container = (LinearLayout)findViewById(R.id.layoutContainer);
View hiddenInfo = getLayoutInflater().inflate(R.layout.dynamic, container, false);
container.addView(hiddenInfo);
LinearLayout hiddenLayout = (LinearLayout)findViewById(R.id.dynamic);
TextView textView = (TextView) findViewById(R.id.text);
textView.setText("Text"+i);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(0, 30, 0, 0);
hiddenLayout.setLayoutParams(layoutParams);
hiddenLayout.addView(textView);
}

I also want to know how to remove all the generated dynamic rows on click remove button.
Replace
LinearLayout hiddenLayout = (LinearLayout)findViewById(R.id.dynamic);
TextView textView = (TextView) findViewById(R.id.text);
with
LinearLayout hiddenLayout = (LinearLayout) hiddenInfo.findViewById(R.id.dynamic);
TextView textView = (TextView) hiddenInfo.findViewById(R.id.text);
And remove this line
hiddenLayout.addView(textView);
I am trying this for 2 days,I am trying to make UIs for the view having two columns in first row,then in second row having three columns,and in third again two columns and so on..And also I have to implement dynamic data(means num of rows/columns are dynamic).
I don't have any idea to implement this type of view.I have also try stragged grid view but this is for dynamic views..but in this I have static 2,3,2,3... columns for 1,2,3,4..rows.Please help me.Any tutorial will be most helpful.
Finally I have solved this problem.I have tried with Raghunandan and user3278416's suggestion.And did all the stuff in runtime except Table layout.Here is the xml file:
<ScrollView android:layout_width="match_parent"
android:layout_height="match_parent">
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/table_layout"
>
And the the two layouts one is for small layout(the second row) and one is for large one(first row):
<?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" >
<RelativeLayout
android:layout_width="130dp"
android:layout_height="160dp"
android:layout_margin="3dp"
android:background="#drawable/big_product_bg" >
<ImageView
android:id="#+id/img_offersrowlayout"
android:layout_width="120dp"
android:layout_height="80dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:scaleType="fitXY"
android:src="#drawable/img_bydefault" />
<TextView
android:id="#+id/txt_title_offerrowlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/img_offersrowlayout"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="8dp"
android:gravity="center_horizontal"
android:singleLine="true"
android:text="BenQ Digital camera"
android:textColor="#color/green_app"
android:textSize="15dp"
android:textStyle="bold" />
The small one:
<RelativeLayout
android:layout_width="90dp"
android:layout_height="160dp"
android:layout_margin="3dp"
android:background="#drawable/big_product_bg" >
<ImageView
android:id="#+id/img_offersrowlayout"
android:layout_width="90dp"
android:layout_height="80dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:scaleType="fitXY"
android:src="#drawable/img_bydefault" />
<TextView
android:id="#+id/txt_title_homesmallrowlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/img_offersrowlayout"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="8dp"
android:gravity="center_horizontal"
android:singleLine="true"
android:text="BenQ Digital camera"
android:textColor="#color/green_app"
android:textSize="15dp"
android:textStyle="bold" />
Now the Java Code:
int leftMargin_small=2;
int topMargin_small=5;
int rightMargin_small=2;
int bottomMargin_small=5;
int j = 0;
while (Show.size()>j) {
try {
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
TableRow.LayoutParams param = new TableRow.LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT, 1.0f);
param.setMargins(leftMargin_small, topMargin_small, rightMargin_small, bottomMargin_small);
LinearLayout layout1 = new LinearLayout(getApplicationContext());
TableRow.LayoutParams param_layout = new TableRow.LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT, 1.0f);
layout1.setLayoutParams(param_layout);
View question = inflater.inflate(R.layout.offers_rowlayout, null);
question.setLayoutParams(param);
//question.setId(pos);
TextView title = (TextView) question.findViewById(R.id.txt_title_offerrowlayout);
title.setText(""+">>"+Show.get(j).get("name"));
View question1 = inflater.inflate(R.layout.offers_rowlayout, null);
//question.setId(pos);
question1.setLayoutParams(param);
TextView title1 = (TextView) question1.findViewById(R.id.txt_title_offerrowlayout);
title1.setText(""+">>"+Show.get(j+1).get("name"));
View question_small = inflater.inflate(R.layout.home_row_small_layout, null);
//question.setId(pos);
question_small.setLayoutParams(param);
TextView title_small = (TextView) question_small.findViewById(R.id.txt_title_homesmallrowlayout);
title_small.setText(""+">>"+Show.get(j).get("name"));
View question1_small = inflater.inflate(R.layout.home_row_small_layout, null);
//question.setId(pos);
question1_small.setLayoutParams(param);
TextView title1_small = (TextView) question1_small.findViewById(R.id.txt_title_homesmallrowlayout);
title1_small.setText(""+">>"+Show.get(j+1).get("name"));
View question2_small = inflater.inflate(R.layout.home_row_small_layout, null);
//question.setId(pos);
question2_small.setLayoutParams(param);
TextView title2_small = (TextView) question2_small.findViewById(R.id.txt_title_homesmallrowlayout);
title2_small.setText(""+">>"+Show.get(j+2).get("name"));
if (gett) {
TableRow tr = new TableRow(getApplicationContext());
TableLayout.LayoutParams trParams = new TableLayout.LayoutParams(
TableLayout.LayoutParams.MATCH_PARENT,
TableLayout.LayoutParams.MATCH_PARENT,1);
// trParams.setMargins(leftMargin, topMargin, rightMargin, bottomMargin);
tr.setLayoutParams(trParams);
layout1.addView(question);
layout1.addView(question1);
tr.addView(layout1);
tablee.addView(tr);
gett = false;
j = j+2;
}
else
{
TableRow tr = new TableRow(getApplicationContext());
TableLayout.LayoutParams trParams = new TableLayout.LayoutParams(
TableLayout.LayoutParams.MATCH_PARENT,
TableLayout.LayoutParams.MATCH_PARENT,1);
layout1.addView(question_small);
layout1.addView(question1_small);
layout1.addView(question2_small);
tr.addView(layout1);
tablee.addView(tr);
gett = true;
j = j+3;
}
} catch (Exception e) {
e.printStackTrace();
}
}
Here Show is the arraylist of hashmap type and tablee is the tablelayout object which I have made in Xml file.
When I create EditText programmatically I have no underline (in the second EditText). Like this: http://oi41.tinypic.com/2ut427d.jpg
When I create an EditText in XML everything is fine, see http://oi44.tinypic.com/nmxdnm.jpg. Where is the error?
This is my XML layout:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="10dp" >
<include layout="#layout/input_title_layout" />
<TableLayout
android:id="#+id/relativeLayout12"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1" >
<TableRow
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="0dp" >
<TextView
style="#style/tvTitleStyle"
android:text="#string/diameter" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left"
android:paddingLeft="5dp"
android:paddingRight="5dp"
android:text=":" />
<EditText
android:id="#+id/diameterValue"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:digits="0123456780."
android:inputType="numberDecimal" />
</TableRow>
</TableLayout>
</LinearLayout>
</ScrollView>
And code to add EditText programatically:
final TableLayout.LayoutParams tableParams = new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.FILL_PARENT, 1f);
final TableRow.LayoutParams rowParams = new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT);
rowParams.bottomMargin = 0;
TableLayout tableLayout = new TableLayout(context);
tableLayout.setLayoutParams(tableParams);
inputLinearLayout.addView(tableLayout);
TableRow tableRowEdit = new TableRow(context);
TextView titleTv = new TextView(context);
titleTv.setTextAppearance(context, R.style.tvTitleStyle);
titleTv.setText(context.getString(context.getResources().getIdentifier(inputTvs[i] , "string", context.getPackageName())));
TextView separatorTv = new TextView(context);
separatorTv.setGravity(Gravity.LEFT);
separatorTv.setPadding(5, 0, 5, 0);
separatorTv.setText(":");
separatorTv.setTextColor(Color.BLACK);
EditText editText = new EditText(context);
editText.setId(i);
tableRowEdit.addView(titleTv);
tableRowEdit.addView(separatorTv);
tableRowEdit.addView(editText);
tableLayout.addView(tableRowEdit);
It's hard to tell exactly what the issue might be given the code you supplied.
-Have you tried setting the layout parameters of the TableRow/TextView/EditText? The TextViews might be taking up all the visible space.
-Are you sure inputLinearLayout has been inflated?
I am trying to display a simple ImageView in a TableRow but for some reason it won't display. If I add another control to another row the imageView does display, so it seems like it is just not forcing the size correctly. My xml is as follows:
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:background="#4B088A"
android:id="#+id/ImageTable">
<TableRow android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dp"
android:id="#+id/ImageTableRow"/>
</TableLayout>
The code that I am using to add the ImageView is:
TableLayout tableLayout = (TableLayout) findViewById(R.id.ImageTable);
TableRow tr = new TableRow(this);
TableRow.LayoutParams lp = new
TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT ,TableRow.LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
m_imageView = new MyImageView(getApplicationContext());
m_imageView.setBackgroundColor(Color.GRAY);
m_imageView.setImageBitmap(charty);
tr.addView(m_imageView);
tableLayout.addView(tr);
try this code
write your xml "activity_main" as
<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" >
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_action_search" />
</TableRow>
</TableLayout>
</LinearLayout>
ic_action_search is your image in drawable folder and write main activity as
public class MainActivity extends Activity
{
ImageView image;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
I have a TableLayout inside a ScrollView, that is I have a scrollable TableLayout! It is populated dynamically when I create Dialog's in different places of an Activity.
Actually everything works fine, but the fact that for every case there's a different header (with a title for each column) on that table and it scrolls along with the rows. As the content of that table is dynamic, the amount (as well as the width) of columns is unknown.
So, basically, that's my problem. I don't see point in posting code, as I need mostly a suggestion/workaround, but if that would help overcome the issue, let me know. Would appreciate some samples very much.
Here is a way :
http://sdroid.blogspot.com/2011/01/fixed-header-in-tablelayout.html
Note that there is a way to have this work every time : what you have to do is create a similar dummy row in the header, and set the texts in both dummies to the longest string you can find in the row (in number of chars, or, even better, do the comparison with Paint.getTextWidths)

Android scrollable TableLayout with a dynamic fixed header is very simple. Follow this steps
Step 1:
Create a TableLayout and use android:layout_alignParentTop="true" this will keep this layout always in top.
Step 2:
With in ScrollView create another TableLayout for contents with out Rows (For Dynamic content).
Step 3:
Add Rows and columns dynamically. While adding each column (TextView) assign the width to an temporary variable.
Ex
tvContentText.measure(0, 0);
tempmaxwidth=tvContentText.getMeasuredWidth();
Step 4:
Check for max width and assign max width to main variable.
Ex:
if (tempmaxwidth > maxwidth)
maxwidth=tempmaxwidth;
Step 5:
After assigning content details. Assign the max width of each column to its header column.
Ex:
TextView tvh1 = (TextView) findViewById(R.id.h1);
tvh1.setWidth(maxwidth);

Well for me I didn't want to go through the trouble of worrying about alignment of columns so I created this first of all:
public static Boolean SET_TABLE_HEADER;
Then I created this function to set my TableHeader:
public void setTableHeader(TableLayout tbl) {
TableRow tr = new TableRow(context);
TextView tcView = new TextView(context);
tcView.setText("Class");
tcView.setTextColor(Color.BLACK);
tcView.setAllCaps(true);
tcView.setTypeface(null, Typeface.BOLD);
tcView.setGravity(Gravity.CENTER_HORIZONTAL);
tr.addView(tcView);
TextView tfView = new TextView(context);
tfView.setText("Fee");
tfView.setTextColor(Color.BLACK);
tfView.setAllCaps(true);
tfView.setTypeface(null, Typeface.BOLD);
tfView.setGravity(Gravity.CENTER_HORIZONTAL);
tr.addView(tfView);
TextView tqView = new TextView(context);
tqView.setText("Available");
tqView.setTextColor(Color.BLACK);
tqView.setAllCaps(true);
tqView.setTypeface(null, Typeface.BOLD);
tqView.setGravity(Gravity.CENTER_HORIZONTAL);
tr.addView(tqView);
// Adding row to Table
tbl.addView(tr);
// Table Header Has Been Set
SET_TABLE_HEADER = false;
}
Then inside my loop:
if (SET_TABLE_HEADER) {
setTableHeader(tbl);
}
Where tbl is the instance of my TableLayout in my view. This works for me.
Of course you will have to initialize SET_TABLE_HEADER to true at the point where you start creating your table.
