    copied!<p>I have an activity with two fragments like this image : <a href="http://img96.imageshack.us/img96/1083/astatus.png" rel="nofollow noreferrer">status A</a> Fragment B is a ListFragment. When user clicks on one row in fragment B. I have show detail. And the UI should like this: <a href="http://img338.imageshack.us/img338/1984/bstatus.png" rel="nofollow noreferrer">status B</a></p> <p>How can I move and resize fragment B?</p> <p>I tried this way but don't know whether it is a correct way or hacky way. I set this layout for the activity.</p> <pre><code>&lt;LinearLayout android:id="@+id/linearLayoutMainPart" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_above="@+id/scrollViewBottomMenu" android:layout_toRightOf="@+id/scrollViewLeftMenu" android:background="@android:color/white" android:orientation="horizontal" &gt; &lt;FrameLayout android:id="@+id/leftContainer" android:layout_width="wrap_content" android:layout_height="match_parent" &gt; &lt;/FrameLayout&gt; &lt;FrameLayout android:id="@+id/rightContainer" android:layout_width="0dip" android:layout_height="match_parent"&gt; &lt;/FrameLayout&gt; &lt;/LinearLayout&gt; </code></pre> <p>I create 3 fragment A, B, C class. When the activity create I add two fragment A, B to leftContainer and rightContainer. (fragment A layout width is fixed). When user click on one row in fragment B. I replace fragment A by another instance of fragment B (with different layout, and using the same data with the old fragment B instance). And replace fragment B in rightContainer by an instance of fragment C.</p> <p>In fragment B class. I have flag to choose layout when onCreateView method is called, something like : </p> <pre><code>if(rightPosition) return B_right_pos_layout; else return B_left_pos_layout; </code></pre> <p>I think I can use the same instance of Fragment B. By doing like this :</p> <pre><code> FragmentB fragmentB = (FragmentB) getSupportFragmentManager().findFragmentByTag(FRAGMENT_B_TAG); fragmentB.setRightPos(false); FragmentTransaction transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(rightContainer, fragmentC); transaction.replace(leftContainer, fragmentB); transaction.commit(); </code></pre> <p>I think this way is more like a hack way. What is the best way?</p>
