i have a table with header row designed in xml. Now i want to add data in the table ( which i get from json array).
I need to scroll data rows vertically without affecting header row, so i created another tablelayout just below the table of header row. Then for each field of each new row, i set layout params in java file and then add the row to second table layout.
But no rows are visible while data is getting printed in the log.I can't figure out where is my mistake.

1st Table Layout has height of match_parent and thus was not giving space to second table layout, so i changed it to wrap content

I am creating an app that would display data from my SQLite database, though I have been successful in displaying the data in Custom ListViews. But I am wondering how would I be able to display data in a Table like form, I can display the first line of data though I don't know where to go from here.

Thanks in advance for any help and suggestions! :D
try something like this
<?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>
Once You have Created the tableLayout Create a table row layout 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/name"
android:layout_weight="0.25"
android:gravity="center"/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:id="#+id/title"
android:layout_weight="0.25"
android:gravity="center"/>
</TableRow>
inside your activity iterate through the values retrieved from the sql and add it to the table
private TableLayout tableLayout;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.table);
tableLayout=(TableLayout)findViewById(R.id.tableLayout);
data.moveToFirst();
do {
View tableRow = LayoutInflater.from(this).inflate(R.layout.table_item,null,false);
TextView name = (TextView) tableRow.findViewById(R.id.name);
TextView title = (TextView) tableRow.findViewById(R.id.title);
name.setText(data.getString(1));
title.setText(data.getString(2));
tableLayout.addView(tableRow);
} while (data.moveToNext());
data.close();
}
Use below code , rows will be created dynamically according to the data , result will be something similar to this

// this method for table title
createtitle(table);
for(int i=0;i<datalist.size();i++){
// this method is creating table rows and filling data
Createtable(table,i);
}
}

You can use this
You can use a custom listview or Recyclerview which is more or less like a listview, it's just an advanced listview to be precise. You can use this documentation to understand recyclerviews https://developer.android.com/training/material/lists-cards.html
I have created Dialog Box with 4 EditText. But now I need to do this by dynamically depends on API response JsonObject count.
Here is my response:
{
"additional_charges":{
"1":"121324324",
"2":"245657687",
"3":"379809733",
"4":"4467797894"
}
}
If "additional_charges", has "1","2","3" ---> I have to show 3
Edittext.
If "additional_charges", has "1","2","3","4" ---> I have to show 4
Edittext in Dialog box.
How to do this?

private void ShowDialog(final String completeUrl, Context context) {
if (NotificationAct.passenger_mobile != null) {
final View view = View.inflate(OngoingAct.this, R.layout.additional_charges, null);
cDialog = new Dialog(OngoingAct.this, R.style.dialogwinddow);
cDialog.setContentView(view);
cDialog.setCancelable(false);
cDialog.show();
FontHelper.applyFont(OngoingAct.this, cDialog.findViewById(R.id.alert_id));
LinearLayout linlay_container = (LinearLayout) findViewById(R.id.chargeType);
//length from json response
int arrayLength = 4;
EditText editText[] = new EditText[0];
for (int i = 0; i < arrayLength; i++) {
editText[i] = new EditText(this);
editText[i].setBackgroundResource(R.color.white);
editText[i].setId(i);
linlay_container.addView(editText[i]);
}
final Button button_success = (Button) cDialog.findViewById(R.id.submitBut);
final Button button_failure = (Button) cDialog.findViewById(R.id.cancelBut);
button_failure.setVisibility(View.VISIBLE);
}
}
Firstly, parse the Json response and get the length of the array.
Then, create a layout container in the Dialog box where you want to add the EditText's.
Then, you can iterate through for loop by creating new EditText object and adding it to the container according to the array list.
Have a look on a code snippets,
LinearLayout linlay_container=(LinearLayout)findViewById(R.id.linlay_container);
//length from json response
int arrayLength=?;
for (int i = 0; i <arrayLength ; i++) {
EditText editText=new EditText(this);
linlay_container.addView(editText);
}
Here, linlay_container is the container layout of Dialog box in which you want to add EditText and arraylength is the array size from your json response.

My problem is that i want to dynamically add a radiobutton infront of each row of my result, which the above code does fine , But since to select one of the row i need to get all the radiobuttons in a radioGroup.This is where i am stuck.it is giving me this error
03-23 22:43:37.807: E/AndroidRuntime(551): Caused by:
java.lang.IllegalStateException: The specified child already has a
parent. You must call removeView() on the child's parent first.
i have no idea what the above is , this line in the above code is giving me the error ->rg.addView(rb);

This is happening because you are adding rb to two different GroupViews (rg and newRow). RadioGroup is a GroupView on it's own and can't add vies to it as wel as to other GroupView.
I think that you are going to have to handle the single selection yourself. Possibly by attaching the same selection listener and keeping a copy of the selected radio button so you can deselect it when another one is selected. On the other hand if you want to have multiple selection you can keep a List with the RadioButton instances and then when needing to check which ones are selected just run though it.
Hope it helps.
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.
