    text
    copied!<p>I created a sample app to test this overlapping issue. </p> <p>I have a fragment type, Fragment1, and I create a new instance of Fragment1 and add it to a FrameLayout in my activity at runtime. I add the fragment with the help of a few buttons.</p> <p>Note: I have given each new instance of Fragment1 a different number(#1, #2, #3, etc.) to display on the UI to help me figure out which fragment I am viewing.</p> <p>So.. here is what I do:</p> <ol> <li>Click on Button 3, create new instance of Fragment1 and add it to Frame1.</li> <li>Click on Button 4, create new instance of Fragment1 and add it to Frame1 and add it to the fragment backstack.</li> <li>Repeat 1 and 2.</li> <li>Repeat 1 and 2.</li> </ol> <p>Now, I have fragments in this order: 1(#1),2(#2),1(#3),2(#4),1(#5),2(#6).</p> <p>I press the back key when viewing fragment #6.</p> <ol> <li>Back key press, UI displays (#5).</li> <li>Back key press, UI displays (#3 AND #5),</li> <li>Back key press, UI displays (#1, #3, AND #5)</li> </ol> <p>It seems fragments are getting displayed ON TOP of each other.</p> <p>WHY? Is there an overlapping issue? How can I clear out this overlapping issue. I thought this would be an issue on the compatibility library... but it is also on 3.0. </p> <p>Code for adding fragments:</p> <pre><code>public int doFragmentChange(int cont1, Fragment frag1, String tag1, int cont2, Fragment frag2, String tag2, boolean addToStack, String stackTag) { FragmentManager fm = getFragmentManager();// getSupportFragmentManager(); FragmentTransaction ft = fm.beginTransaction(); if (frag1 != null) { ft.replace(cont1, frag1, tag1); } if (frag2 != null) { ft.replace(cont2, frag2, tag2); } // add fragment to stack if (addToStack) ft.addToBackStack(stackTag); return ft.commit(); } </code></pre>
