Hi, I need to construct a table like grid with massive data, for
example 100 * 60.
The code I used is dataGrid.setText(i, j, value), so I need to call it
6000 times, and the value varied from null data to strings with
unfixed length.
It took nearly 4 seconds to display grid, regardless of the data transfer time.
Date d3 = new Date();
for (int i = 0; i < result.length; i++) {
String[] rowValues = result[i];
for (int j = 0; j <rowValues.length;
j++) {
String value = rowValues[j];
if (value != null) {
dataGrid.setText(i, j,
value);
}
}
}
d2 = new Date();
l.setText((d2.getTime() - d1.getTime()) /
1000.0 + "_" +
(d2.getTime() - d3.getTime()) / 1000.0 + "");
Is there any other method to speed up these action such as add a row
in one time?
Anyone could help me, or point out whether my codes have some problems?
