Adding data to the rows in Table layout

Question

Am trying to create an EPG kind of layout and i referred this (Print out ArrayList content in Android TableLayout) And my problem is when am trying to add rows, they are getting added as a new rows but i need those values to be added in existing rows. Here is my XML file:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:orientation="vertical" >



    <TableLayout
        android:id="@+id/myTableLayout"
        android:layout_width="match_parent"
        android:layout_height="354dp"
        android:background="#6495ED"
        android:stretchColumns="*" >


     <TableRow
            android:id="@+id/tablerow1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >

             <TextView
                 android:id="@+id/textView1"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"

                 android:text="Some Text " 
                />

             <TextView
             android:id="@+id/textView2"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"

             android:text="Some Text"
              />

             <TextView
             android:id="@+id/textView3"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"

             android:text="Some Text" />



        </TableRow>
</TableLayout>

and my java file is

TableLayout table = (TableLayout) findViewById(R.id.myTableLayout);
            for(int i=0;i<channel_arraylist.size();i++)
            {

                TableRow tableRow2=new TableRow(VideoDatabase1.this);
                localchannel1= channel_arraylist.get(i);

                  TextView tvid=new TextView(VideoDatabase1.this);
                  tvid.setText(""+Integer.toString(localchannel1.getID()));
             tableRow2.addView(tvid);

            table.addView(tableRow2);

yes data is not added in table rows.. instead its getting added below the layout — user1950448

My answer for your question.

    private ArrayList<String> data = new ArrayList<String>();
    private ArrayList<String> data1 = new ArrayList<String>();
    private TableLayout table;    

    data.add("Samsung");
    data.add("Apple");
    data.add("Pixle");
    data.add("Vivo");
    data1.add(" $109");
    data1.add(" $200");
    data1.add(" $399");
    data1.add(" $290");        


    table = (TableLayout)findViewById(R.id.mytable);

    for(int i=0;i<data.size();i++)
    {
        TableRow row=new TableRow(this);
        String phone = data.get(i);
        String amount = data1.get(i);
        TextView tv1=new TextView(this);
        tv1.setText(phone);
        TextView tv2=new TextView(this);
        tv2.setText(amount);
        row.addView(tv1);
        row.addView(tv2);
        table.addView(row);
    }

Try to replace

TableRow tableRow2=new TableRow(VideoDatabase1.this);

to

TableRow tableRow2=((TableRow)table.getChildAt(0));

Also, set a breakpoint in line:

for(int i=0;i<channel_arraylist.size();i++)

And watch your "table" variable in debug mode. It must contain at least 1 child. It must help.

Regarding your question: TableRow must be added below because you add a new row to tableLayout. And it's normally.

Hi @Panda first thanks for your answer. I tried your code. but its showing class cast exception.Am a newbie. so can you explain me in detail about this

user2558337 Over a year ago

Sorry 4 this. Yes you can cast right side to (TableRow). I've update my answer.

user1950448 Over a year ago

The values are getting inserted in right side of table layout but not on table layout..

I finally found out the solution. To add the views to the particular table just do

TextView tvid=(TextView)findViewById(R.id.textView1); 
          tvid.setText(localchannel1.getName());

Here id refers to the id you declared in your layout file. Simply this will insert the value in the corresponding column. Thanks for everything.

        {
            db.endTransaction();
            db.close();
        }
    }

    public interface OnFragmentInteractionListener {
           void onFragmentInteraction(Uri uri);
    }
}

Maybe DON'T YELL and fixup the formatting. Also, some words describing how this addresses the question at hand instead of just a wall of code would make this answer more useful.
