Creating table layout dynamically in android

In first(Creating table layout from xml layout) , table layout creating with xml layout, Now creating table layout from programmatically in android.

public class MainActivity extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

   super.onCreate(savedInstanceState);

   

   String[] row = { "ROW1", "ROW2", "Row3", "Row4", "Row 5", "Row 6",

"Row 7" };

        String[] column = { "COLUMN1", "COLUMN2", "COLUMN3", "COLUMN4",

"COLUMN5", "COLUMN6" };

  int rl=row.length; int cl=column.length;

   

   Log.d("--", "R-Lenght--"+rl+"   "+"C-Lenght--"+cl);

   

ScrollView sv = new ScrollView(this);

   TableLayout tableLayout = createTableLayout(row, column,rl, cl);

   HorizontalScrollView hsv = new HorizontalScrollView(this);

   

   hsv.addView(tableLayout);

sv.addView(hsv);

setContentView(sv);

}

public void makeCellEmpty(TableLayout tableLayout, int rowIndex, int columnIndex) {

   // get row from table with rowIndex

   TableRow tableRow = (TableRow) tableLayout.getChildAt(rowIndex);

   // get cell from row with columnIndex

   TextView textView = (TextView)tableRow.getChildAt(columnIndex);

   // make it black

   textView.setBackgroundColor(Color.BLACK);

}

public void setHeaderTitle(TableLayout tableLayout, int rowIndex, int columnIndex){

   // get row from table with rowIndex

   TableRow tableRow = (TableRow) tableLayout.getChildAt(rowIndex);

   // get cell from row with columnIndex

   TextView textView = (TextView)tableRow.getChildAt(columnIndex);

   

   textView.setText("Hello");

}

private TableLayout createTableLayout(String [] rv, String [] cv,int rowCount, int columnCount) {

   // 1) Create a tableLayout and its params

   TableLayout.LayoutParams tableLayoutParams = new TableLayout.LayoutParams();

   TableLayout tableLayout = new TableLayout(this);

   tableLayout.setBackgroundColor(Color.BLACK);

   // 2) create tableRow params

   TableRow.LayoutParams tableRowParams = new TableRow.LayoutParams();

   tableRowParams.setMargins(1, 1, 1, 1);

   tableRowParams.weight = 1;

   for (int i = 0; i < rowCount; i++) {

       // 3) create tableRow

       TableRow tableRow = new TableRow(this);

       tableRow.setBackgroundColor(Color.BLACK);

       for (int j= 0; j < columnCount; j++) {

           // 4) create textView

           TextView textView = new TextView(this);

         //  textView.setText(String.valueOf(j));

           textView.setBackgroundColor(Color.WHITE);

           textView.setGravity(Gravity.CENTER);

           

           String s1 = Integer.toString(i);

String s2 = Integer.toString(j);

String s3 = s1 + s2;

int id = Integer.parseInt(s3);

Log.d("TAG", "-___>"+id);

            if (i ==0 && j==0){

            textView.setText("0==0");

            } else if(i==0){

            Log.d("TAAG", "set Column Headers");

            textView.setText(cv[j-1]);

            }else if( j==0){

            Log.d("TAAG", "Set Row Headers");

            textView.setText(rv[i-1]);

            }else {

            textView.setText(""+id);

            // check id=23

            if(id==23){

            textView.setText("ID=23");

             

            }

            }

           // 5) add textView to tableRow

           tableRow.addView(textView, tableRowParams);

       }

       // 6) add tableRow to tableLayout

       tableLayout.addView(tableRow, tableLayoutParams);

   }

   return tableLayout;

}

}

Out put looks like this:

Happy Coding!!!
