In Android tablet fragment, the two adjacent cells in the same row of tablelayout are merged into one cell for display?

The effect of merging two cells into one cell is shown in:

How to achieve the above results:

1. Get tablelayout.

2. Use tablelayout obtained in the first step to call the following method:

Private void appendtable (tablelayout ){
Int size = filelist. Size ();
Int columnnum = 4;
Boolean isspancell = false;
Boolean startnewrow = true;
Boolean endofonerow = false;
Table. setpadding (10, 0, 5, 0 );

// Obtain the fragment width of tablelayout,
Int width = fragment. getview (). getwidth ();
Tablerow ROW = NULL;
For (Int J = 0; j <size; j ++ ){
// The red code below todo is the rule for merging two adjacent cells I have defined. You can define your own merging rules.
If (J % columnnum = 0 ){
Startnewrow = true;
}
Else {
Startnewrow = false;
}
If (J % columnnum = 3 | j = size-1 ){
Endofonerow = true;
}
Else {
Endofonerow = false;
}
If (J % 5 = 0 | (J + 2) % 20 = 0 ){
Isspancell = true;
}
Else {
Isspancell = false;
}
If (startnewrow ){
Row = new tablerow (this. context );
}
View cell = generatecell (J, isspancell, width );

// Add new cells to the current row

Row. addview (cell );

// If a row ends, tablelayout adds the current row.

If (endofonerow ){
Row. setpadding (0, 0, 0, 10 );
Tablelayout. addview (ROW );
}
}
}

3. The method for green in step 2 is as follows:

Private view generatecell (INT index, Boolean isspanrow, int width ){
Viewholder holder = new viewholder ();
View view = NULL;
View = Inflater. Inflate (R. layout. file_item, null );

Tablerow. layoutparams TLP = new tablerow. layoutparams ();
TLP. span = 2; // tablerow. layoutparams, set cross-two columns
Linearlayout layout = new linearlayout (context );
Holder. filecreatoricon = (imageview) view
. Findviewbyid (R. Id. file_creator_icon );
Holder. filegridviewitemlayout = (relativelayout) view
. Findviewbyid (R. Id. file_gridview_item_relativelayout );
Holder. fileupdatedtime = (textview) view
. Findviewbyid (R. Id. file_upload_time );
Holder. fileownername = (textview) view. findviewbyid (R. Id. file_text_owner );
Holder. filename = (textview) view. findviewbyid (R. Id. file_name );

Layout. setpadding (0, 0, 10, 0 );

// Determine the width of the current cell based on whether it is cross-column, and dynamically calculate it based on the width of the current fragment.
If (isspanrow ){
Layout. addview (view, (width-40)/5*2 + 10,150 );
Layout. setlayoutparams (TLP );
}
Else {
Layout. addview (view, (width-40)/5,150 );
}

// Display the method of an item, which can be implemented according to your own situation
Showfileinfo (holder, index, view );
Return layout;
}
