Answer 1

|*| Table Layout for 3 x 3 buttons using Java Code :

Set number of Rows in tblRowCwtVal
Set number of Columns in tblColCwtVal
Set the String | Drawable in tblAryVar

In this example, we have used button for each table view. You can use TextView | ImageView and modify accordingly

int tblRowCwtVal = 3;
int tblColCwtVal = 3;
int[][] tblAryVar =
     {
        {R.drawable.ic_name, R.drawable.ic_name, R.drawable.ic_name},
        {R.drawable.ic_name, R.drawable.ic_name, R.drawable.ic_name},
        {R.drawable.ic_name, R.drawable.ic_name, R.drawable.ic_name}
     };

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.srn_nam_uic);

    namRelLyoVar = (RelativeLayout) findViewById(R.id.NamSrnLyoUid);

    TableLayout namTblLyoVar = new TableLayout(this);
    TableLayout.LayoutParams tblLyoRulVar = new TableLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    TableRow.LayoutParams btnLyoRulVar = new TableRow.LayoutParams(50,50);

    for(int tblRowIdxVar = 0; tblRowIdxVar < tblRowCwtVal; tblRowIdxVar++)
    {
        TableRow tblRowVar = new TableRow(this);

        for(int tblColIdxVar = 0; tblColIdxVar < tblColCwtVal; tblColIdxVar++)
        {
            Button namIdxBtnVar = new Button(this);
            Drawable DrwablIdxVar = getResources().getDrawable(tblAryVar[tblRowIdxVar][tblColIdxVar]);
            DrwablIdxVar.setColorFilter(Color.rgb(0,128,0), PorterDuff.Mode.SRC_IN);
            namIdxBtnVar.setBackground(DrwablIdxVar);

            tblRowVar.addView(namIdxBtnVar, btnLyoRulVar);
        }
        namTblLyoVar.addView(tblRowVar, tblLyoRulVar);
    }

    namTblLyoVar.setLayoutParams(tblLyoRulVar);
    namRelLyoVar.addView(namTblLyoVar);
}
