display Multidimensional Arrays android












1














I'm using android studio and with opencv 3.4.0. I want to display a Multidimensional Array in text view. I have an a array "candidats_result" and I copied her values into a Multidimensional array " finale". after runing my code I got this result in emulator display. what I have to change in my code to get the text displayed



double  R_finale = new double[20][20];

int ZZ = 0;
int ZE = 0;
int EE = 0;

for(int i=0;i<19;i++){
for(int j=0;j<19;j++){
R_finale[i][j] = candidats_result[ZZ];
ZZ++;
}
}

String finale = new String [20][20];
//showing the array in android
for(int i=0;i<19;i++) {
for (int j = 0; j < 19; j++) {
finale[i][j] = Double.toString(R_finale[i][j]);
}
}
String details = new String[20][20];
StringBuilder builder = new StringBuilder();
for ( int i = 0 ; i<20;i++) {
for (int j = 0; j < 20; j++) {
details[i][j] = String.valueOf(R_finale [i][j]);
builder.append(details + ";");
}
}


textView.setText(String.valueOf(builder));
