i wanna create button 1 to 9 and i want to do that in loop. But in each 3 count, i want to create a new LinearLayout.
final LinearLayout[] ll2 = new LinearLayout[10]; // create an empty array;
for(int i=1; i<=9;i++)
{
Button btnNums = new Button(this);
final LinearLayout[] ll2 = new LinearLayout[10]; // create an empty array;
for(int i=1; i<=9;i++)
{
Button btnNums = new Button(this);
btnNums.setText(i+"");
ll.addView(btnNums);
if(i%3==0){
ll2[i] = ll;
ll = null;
}
}
layout.addView(ll2[0]);
btnNums.setText(i+"");
ll.addView(btnNums);
if(i%3==0){
ll2[i] = ll;
ll = null;
}
}
layout.addView(ll2[0]);
This does not work. I get no error but when o run the app, it is stopped to work. What's the problem?
I used it in my Project and it worked for me, i used it like this. Hope it helps
Declare empty array at class level:
LinearLayout[] imageLayoutContainers = new LinearLayout[10];
And then in on onCreate methord :
for (int i = 0; i < imageLayoutContainers.length; i++) {
imageLayoutContainers[i] = new LinearLayout(this);
imageLayoutContainers[i].setOrientation(LinearLayout.VERTICAL);
imageLayoutContainers[i].setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
imageLayoutContainers[i].setBackgroundResource(imagesIds[i]);
}
It worked, thanks
