动态创建linearlayout和textviews中的内存泄漏

Question

I am having problem creating lots of LinearLayout and TextView basically my app displays text and I dynamically create rows( LinearLayout ) and words( TexView ) in the corresponding row. Now my app also uses FragmentStatePagerAdapter so I can "change the page". I have no problem with that. The problem is when I redirect to my own activity with a new textsize it somehow leaks when adding rows.

 int threshold = 25;
 int tw = 0;
 LinearLayout ll = rootView.findViewById(R.id.container);
 LinearLayout row = new LinearLayout(a);
  for(int x = 0;x<words.size();x++)
 {
   tw+=words.get(x).length;
   TextView tv = new TextView(a);
   tv.setText(words.get(x));
   if(tw > threshold)
   {
        ll.addView(row)  <----- this is where out of memory points me
        row = new LinearLayout(a);
        tw = 0;
        x-=1;
   }
   else
        row.addView(tv);

}

Now I also tried dumping the heap and analyzing with mat but the dump I am creating has an invalid header error so I don't know where the actual leak comes from other than the actual error log I have in logcat that points to the ll adding rows which I don't know if is the right place to look into.

Edited : Some added info. It seems the problem occurs when I am adjusting the row height through linearlayout params because when i set my own default which is 50 it is usually just fine. Anyone one knows the reason for this?

Answer 1

Your loop may end into a dead loop for some conditions.

For instance,if your words list contains a String which length is over threshold (25),the if statement( tw > threshold ) would forever evaluate to true,and because you also minus loop count x by one,this is where dead loop happens.
