The rows get miss-aligned when scroll horizontally

[aditeTestAndroid]

Hi. this library is really helpful thank you for it. I am using this table view in multiple activities and fragments.Its like clicking on first table view's button directs to other table-view. Problem is that when first load the table view data and scroll horizontally,it miss aligned rows as mentioned in this: https://github.com/evrencoskun/TableView/issues/75#issuecomment-380322778. there is very important for me. please please help me and fix this bug. thanks.

Hi, I think I have the same issue. I basically started with the example from the readme.md and extended the missing classes from the sample application and then added some of my data. It happens with a dataset of about ~1800 rows and ~40 columns.

I attached a screen capture. In the second half you can see that for some misaligned rows, if I hit the right one, I can even scroll only a part of the table horizontally.

Hi @mettyw ,Did you find any solution for above issue?

[mettyw]

Hi @aditeTestAndroid no, not really. But it became less urgent: after I implemented proper column row and cell layouts with more padding the issue is virtually gone for my main test device. I guess this is because I now show less items on the screen at the same time. I think this is a timing or synchronization issue of some sort.

But even if it is not happening on my main test device anymore I fear that users of my app with larger screens or less powerful devices are still affected.

[aditeTestAndroid]

Hi @mettyw Thank you for your reply. As my app is basically for Tablet devices and i am facing this issue very frequently. Can you share your column and row layouts here? it will be helpful.

@Override
public int getColumnHeaderItemViewType(int columnPosition) {
    return columnPosition;
}

@Override
public int getRowHeaderItemViewType(int rowPosition) {
    return rowPosition;
}

@Override
public int getCellItemViewType(int columnPosition) {
    return columnPosition;
}

Has anyone found a solution to this other than reducing the amout of visible cells yet (i already just have about 50 cells on display)? @nikitoSha comment didn't help me at all...

Hi, @tvaTIS . Try to set like this in adapter:

@Override
public int getColumnHeaderItemViewType(int columnPosition) {
	return 0;
}

@Override
public int getRowHeaderItemViewType(int rowPosition) {
	return 0;
}

@Override
public int getCellItemViewType(int columnPosition) {
	return columnPosition;
}

[tva-TIS]

Hasn't changed anything either. I found out that the problem doesn't occur when the table is build entirely at once with setAllItems (so without calls to addRow or addColumn), so that is gonna be the way i'm gonna go with for now. Thanks anyway.

[fiterzs]

@tva-TIS I also met the same problem. If I replace the CELL content for many times, it will appear disordered display. Have you solved your problem? @nikitoSha I tried your method, but it didn't work,im use 0.8.9.2 version please Help me ,thanks @mettyw How did you solve the problem?

[tva-TIS]

@fiterzs

@tva-TIS I also met the same problem. If I replace the CELL content for many times, it will appear disordered display. Have you solved your problem?

As I wrote, the problem only occurs when addRow or addColumn is called in my project. Maybe setting content does too. I solved it by tossing the table whenever the data changes and rebuild it entirely. Not very efficient but does the job...

[LunevNF]

@fiterzs Can you share the sample project with this bug? Clear empty project with your adapter, layout, init-class? I will try this and correct it. After - publish normal variant.

[LunevNF]

You can create zip-archive with sample project and share via dropbox or google disk

[fiterzs]

@nikitoSha Thank you,I have uploaded the simple project Click the ABCD button several times at random and move the view to the last area. You will see this error https://github.com/fiterzs/test @tva-TIS Thank you Again

[fiterzs]

@nikitoSha I tested it, and this problem exists even in the demo example Scroll the view to the end, just replace the content of any column, the alignment of the table will be problematic It shows the same situation as @mettyw Can you share how you solved this problem? Thank you

[fiterzs]

is easy to happen after 12 columns. If I fill in blank cells, can find that the cell size is not the same as the previous cells after 12 columns.

@fiterzs Hi, I'm very busy, but I will try to help today. Content replacement - yes, I have the solution. I will do it today and answer

[fiterzs]

thank you very much for your help, it’s okay, fix this error when you are free Thank you again

@fiterzs Hi, do you resolve this issue? If no, so your solution is (in file Edsanzhu.java):

    @Override
    public void onClick(View v) {
        Cell cell;
        ArrayList<Integer> result = new ArrayList<Integer>();
        String id;
        switch (v.getId()){
            case R.id.buttonA:
                result = mangerTable.setBlank();
                id =result.get(0).toString()+"-"+result.get(1).toString();
                cell = new Cell(id,"A");
                cell.color = Color.RED;
                Log.d("Tag","Cell id ="+id);
                tableViewAdapterMain.changeCellItem(result.get(0),result.get(1),cell);
                break;
            case R.id.ButtonB:
                result = mangerTable.setPlayer();
                id =result.get(0).toString()+"-"+result.get(1).toString();
                cell = new Cell(id,"B");
                cell.color = Color.BLUE;
                Log.d("Tag","Cell id ="+id);
                tableViewAdapterMain.changeCellItem(result.get(0),result.get(1),cell);
                break;
            case  R.id.ButtonC:
                result = mangerTable.setTie();
                id =result.get(0).toString()+"-"+result.get(1).toString();
                cell = new Cell(id,"C");
                cell.color = Color.GREEN;
                Log.d("Tag","Cell id ="+id);
                tableViewAdapterMain.changeCellItem(result.get(0),result.get(1),cell);
                break;
            case  R.id.ButtonD:
                result = mangerTable.setBack();
                id =result.get(0).toString()+"-"+result.get(1).toString();
                cell = new Cell(id," ");
                //   cell.color = Color.GREEN;
                Log.d("Tag","Cell id ="+id);
                tableViewAdapterMain.changeCellItem(result.get(0),result.get(1),cell);
                break;
        }

        tableViewAdapterMain.getCellRecyclerViewAdapter().notifyDataSetChanged();
        //tableViewAdapterMain.getColumnHeaderRecyclerViewAdapter().notifyDataSetChanged();
        //tableViewAdapterMain.getRowHeaderRecyclerViewAdapter().notifyDataSetChanged();
        mainTableview.scrollToColumnPosition(result.get(0),result.get(1));
    }

So, after that, you just need to complete this, because if you comment scroll to column, you can see, that your columns header row is scrollable (I don't know why, cannot search the reason now).

[fiterzs]

@nikitoSha Thank you very much for your help. Your method can indeed solve the problem of cell alignment, but the scrolling of rows and columns is still not precise. I don’t know if there is a way to get the column numbers visible on the left and right sides of the tableiew in the currently displayed content For example, the currently visible column number on the left and the largest visible column number on the right

Thank you again

After the 12th column, the display of rows and columns cannot be aligned. But the alignment problem of CELL is solved I am also very confused about this problem, thank you very much for your help, sorry to trouble you

[LunevNF]

@fiterzs okay, I will check it now

[LunevNF]

For example, the currently visible column number on the left and the largest visible column number on the right

This library doesn't support this feature yet for now. You can indicate info (for a example using TextView) about scroll opportunity to the right, or duplicate your main table with one column and place it on the right. When user scroll main table to the end (right), you just set visibility to GONE, and set to Visible, when main table hides last column

@nikitoSha

okay, I will check it now

Thank you for your contribution. To express my gratitude, I would like to buy you a cup of coffee. Please give me your paypay account, If this problem is difficult to solve, I will look for other solutions, thank you again for your kind help

How fast you need to solve this problem? It’s okay, it’s not urgent, when you have free time. I can do other things first.

[fiterzs]

@nikitoSha Hi nikitoSha. I gave up the original layout, so this problem was temporarily solved. Sorry to disturb you Thank you again for your help.

[LunevNF]

@fiterzs Hi, Great! Good luck!

[aydinozkan]

@Override
public int getColumnHeaderItemViewType(int columnPosition) {
    return columnPosition;
}

@Override
public int getRowHeaderItemViewType(int rowPosition) {
    return rowPosition;
}

@Override
public int getCellItemViewType(int columnPosition) {
    return columnPosition;
}

Don't know how but this fixed the issue for me :)

[Mohamadkotb]

Has anyone found a solution?

[ReejeshPK]

content_container.setHasFixedWidth(true);

Setting this to false solved the issue,

content_container.setHasFixedWidth(false);

where content_container is

   <com.evrencoskun.tableview.TableView
        android:id="@+id/content_container"
