java - Change TextureView Size at Runtime -

i working on streaming mp4 textureview app working on. have textureview displaying video need resize match screen size on rotation. after trial , error seems problem textureview cannot made larger containing view. have tried resize container view unable center textureview correctly on screen.

 public void onorientationchanged(int orientation) {                 if(islandscape(orientation)){                     mytexture.setrotation(-90);                     relativelayout.layoutparams params = new           relativelayout.layoutparams(relativelayout.layoutparams.wrap_content, relativelayout.layoutparams.wrap_content); params.width = height;                     params.height = (height * 9)/16;                     params.addrule(relativelayout.center_in_parent, relativelayout.true);                       mytexture.setlayoutparams(params);                     mytexture.getlayoutparams().height = (height * 9)/16;                     mytexture.getlayoutparams().width = height;                      rl.requestlayout();                     rl.invalidate();                     rl.recomputeviewattributes(mytexture);                      log.v("view size", "width tex: " + mytexture.getwidth());                     log.v("view size", "height tex: " + mytexture.getheight());                     log.v("view size", "width tex parent: " + rl.getwidth());                     log.v("view size", "height tex parent : " + rl.getheight());                  }       <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context=".myactivity"     android:id="@+id/mediaparent"     android:layout_centerinparent="true"     android:paddingleft="0dp"     android:paddingright="0dp"     android:paddingtop="0dp"     android:paddingbottom="0dp">          <textureview             android:layout_width="360dp"             android:layout_height="203dp"             android:id="@+id/surface"             android:layout_alignparenttop="true"             android:layout_centerhorizontal="true" />      <button         style="?android:attr/buttonstylesmall"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="new button"         android:id="@+id/button"         android:layout_alignparentbottom="true"         android:layout_centerhorizontal="true" />    </relativelayout>
