我想在我的活动中使用VIDeoVIEw播放视频,并在单击按钮时使其成为全屏和横向模式(带有隐藏的虚拟按钮和状态栏).

但是它无法隐藏虚拟按钮,并且底部有一条白线.

This my activity code:

public class VIDeoActivity extends Activity {private VIDeoVIEw mVIDeoVIEw;private String mUrl;private button mFullScreen;private static String TAG = VIDeoActivity.class.getname();@OverrIDeprotected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    Log.d(TAG,"onCreate");    setContentVIEw(R.layout.vIDeo);    mVIDeoVIEw = (VIDeoVIEw) findVIEwByID(R.ID.vIDeo);    mFullScreen = (button) findVIEwByID(R.ID.fullscreen);    file file = new file(Environment.getExternalStorageDirectory(),"vIDeo.mp4");    mVIDeoVIEw.setVIDeoPath(file.getPath());    mVIDeoVIEw.start();    mFullScreen.setonClickListener(new VIEw.OnClickListener() {        @OverrIDe        public voID onClick(VIEw v) {            enterFullScreen();            mFullScreen.setVisibility(VIEw.GONE);        }    });}@OverrIDeprotected voID onDestroy() {    super.onDestroy();    Log.d(TAG,"onDestroy");}private voID enterFullScreen(){    getwindow().setFlags(WindowManager.LayoutParams.FLAG_FulLSCREEN,WindowManager.LayoutParams.FLAG_FulLSCREEN);//设置全屏    this.setRequestedOrIEntation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//设置横屏    getwindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);//常亮    relativeLayout.LayoutParams layoutParams = new relativeLayout.LayoutParams(      relativeLayout.LayoutParams.MATCH_PARENT,      relativeLayout.LayoutParams.MATCH_PARENT    );    layoutParams.addRule(relativeLayout.AliGN_PARENT_BottOM);    layoutParams.addRule(relativeLayout.AliGN_PARENT_top);    layoutParams.addRule(relativeLayout.AliGN_PARENT_left);    layoutParams.addRule(relativeLayout.AliGN_PARENT_RIGHT);  }}

vIDeo.xml

 <?xml version="1.0" enCoding="utf-8"?>    <relativeLayout        xmlns:androID="http://schemas.androID.com/apk/res/androID"        androID:orIEntation="vertical"    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent">    <VIDeoVIEw        androID:ID="@+ID/vIDeo"        androID:layout_wIDth="match_parent"        androID:layout_height="match_parent"        androID:padding="0dp"/>    <button        androID:ID="@+ID/fullscreen"        androID:layout_wIDth="match_parent"        androID:layout_height="wrap_content"        androID:visibility="visible"        androID:text="Fullscreen"/></relativeLayout>

解决方法:

在横向模式下尝试此 *** 作.

<VIDeoVIEw androID:ID="@+ID/vIDeo"    androID:layout_wIDth="fill_parent"    androID:layout_height="wrap_content"    androID:layout_alignParentleft="true"   androID:layout_alignParentRight="true"   androID:layout_alignParentBottom="true"   androID:layout_alignParenttop="true"    />

隐藏虚拟按钮添加以下代码：

getwindow().getDecorVIEw().setsystemUIVisibility(VIEw.SYstem_UI_FLAG_HIDE_NAVIGATION);

原始尺寸

         displayMetrics metrics = new displayMetrics();  getwindowManager().getDefaultdisplay().getMetrics(metrics);         androID.Widget.linearLayout.LayoutParams params = (androID.Widget.linearLayout.LayoutParams) vIDeoVIEw.getLayoutParams();         params.wIDth =  (int) (300*metrics.density);         params.height = (int) (250*metrics.density);         params.leftmargin = 30;         vIDeoVIEw.setLayoutParams(params);

全屏尺寸

         displayMetrics metrics = new displayMetrics(); getwindowManager().getDefaultdisplay().getMetrics(metrics);         androID.Widget.linearLayout.LayoutParams params = (androID.Widget.linearLayout.LayoutParams) vIDeoVIEw.getLayoutParams();         params.wIDth =  metrics.wIDthPixels;         params.height = metrics.heightPixels;         params.leftmargin = 0;         vIDeoVIEw.setLayoutParams(params);
