今天遇到个问题,使用fragmentTransaction.replace替换后的内容不能全屏。。

FragmentManager fragmentManager = getSupportFragmentManager();  FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();  Fragment playFragment = new ColumnFragment();  fragmentTransaction.replace(R.id.fragment_play, playFragment);  fragmentTransaction.commit();

<li><li>fragment_play        android:layout_width=fill_parent        android:layout_height=fill_parent></linearlayout></linearlayout>
从网上查找了相关的资料,农民伯伯的。但是不能解决。

    把要替换的内容使用FrameLayout后问题解决。

<li><framelayout android:background="#ccc" android:id="@+id/fragment_play" android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical">    </framelayout></linearlayout>
