由于我是Java和Android应用程序的新手，我不得不问这个问题，因为我工作了10个小时并且无法实现任何目标。我在eclipse中制作了一个全屏的网络应用程序，但我看不到那里的视频。这是我的代码：
Tarim.java
package com.tarim.tarimvideo;

private static final int AUTO_HIDE_DELAY_MILLIS = 3000;
private static final boolean TOGGLE_ON_CLICK = true;
private static final int HIDER_FLAGS = SystemUiHider.FLAG_HIDE_NAVIGATION;
private SystemUiHider mSystemUiHider;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tarim);
final View controlsView = findViewById(R.id.fullscreen_content_controls);
final View contentView = findViewById(R.id.fullscreen_content);
WebView webView = (WebView)findViewById(R.id.tarayici);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.youtube.com/watch?v=W8SCqLkHDqw");
// Set up an instance of SystemUiHider to control the system UI for
// this activity.
mSystemUiHider = SystemUiHider.getInstance(this, contentView,
HIDER_FLAGS);
mSystemUiHider.setup();
mSystemUiHider
.setOnVisibilityChangeListener(new SystemUiHider.OnVisibilityChangeListener() {
// Cached values.
int mControlsHeight;
int mShortAnimTime;
@Override

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
// If the ViewPropertyAnimator API is available
// (Honeycomb MR2 and later), use it to animate the
// in-layout UI controls at the bottom of the

if (mControlsHeight == 0) {
mControlsHeight = controlsView.getHeight();
}
if (mShortAnimTime == 0) {
mShortAnimTime = getResources().getInteger(
android.R.integer.config_shortAnimTime);
}
controlsView
.animate()
.translationY(visible ? 0 : mControlsHeight)
.setDuration(mShortAnimTime);
} else {
// If the ViewPropertyAnimator APIs aren't
// available, simply show or hide the in-layout UI
// controls.
controlsView.setVisibility(visible ? View.VISIBLE
: View.GONE);
}
if (visible && AUTO_HIDE) {
// Schedule a hide().
delayedHide(AUTO_HIDE_DELAY_MILLIS);
}
}
});
// Set up the user interaction to manually show or hide the system UI.
contentView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (TOGGLE_ON_CLICK) {
mSystemUiHider.toggle();
} else {
mSystemUiHider.show();
}
}
});
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Trigger the initial hide() shortly after the activity has been
// created, to briefly hint to the user that UI controls
// are available.
delayedHide(100);
}
View.OnTouchListener mDelayHideTouchListener = new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
if (AUTO_HIDE) {
delayedHide(AUTO_HIDE_DELAY_MILLIS);
}
return false;
}
};
Handler mHideHandler = new Handler();
Runnable mHideRunnable = new Runnable() {
@Override
public void run() {
mSystemUiHider.hide();
}
};
private void delayedHide(int delayMillis) {
mHideHandler.removeCallbacks(mHideRunnable);
mHideHandler.postDelayed(mHideRunnable, delayMillis);
}
}

请注意我在这个Java中的东西只有10个小时，所以如果你能解释我这么简单，那就太棒了。

在没有Flash帮助的情况下，WebView看起来不可能。请看这个：Youtube in a webview（用于参考）。看一下flash演示：Flash demo。最后this也可能有用，它是Android的YouTube API。

只需将.html文件放入SDCARD中，其中包含您的视频链接。（将视频链接提及为content:\\）。并将该.html文件加载到网页视图。

首先关心编码。这是一个article with a working example和一些为Android webkit编码视频的指南。
然后......当我不得不面对这个问题时，我不得不研究一下并找到一些有用的答案。基本上你必须像本机浏览器那样打开视频
public class InredisChromeClient extends WebChromeClient implements OnCompletionListener, OnErrorListener {
private InterfazWebInredis interfazWeb; // Use Your WebView instance instead
private VideoView mCustomVideoView;
private LinearLayout mContentView;
private FrameLayout mCustomViewContainer;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
private LinearLayout mErrorConsoleContainer;
static final FrameLayout.LayoutParams COVER_SCREEN_GRAVITY_CENTER = new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.FILL_PARENT, Gravity.CENTER);
public InredisChromeClient(InterfazWebInredis iwi) {
super();
this.interfazWeb = iwi;
}
public void onShowCustomView(View view, CustomViewCallback callback) {
// super.onShowCustomView(view, callback);
if (view instanceof FrameLayout) {
mCustomViewContainer = (FrameLayout) view;
mCustomViewCallback = callback;
mContentView = (LinearLayout) interfazWeb.findViewById(R.id.mainContainer);
if (mCustomViewContainer.getFocusedChild() instanceof VideoView) {
mCustomVideoView = (VideoView) mCustomViewContainer.getFocusedChild();
// frame.removeView(video);
mContentView.setVisibility(View.GONE);
mCustomViewContainer.setVisibility(View.VISIBLE);
interfazWeb.setContentView(mCustomViewContainer);
mCustomVideoView.setOnCompletionListener(this);
mCustomVideoView.setOnErrorListener(this);
mCustomVideoView.start();
}
}
}
public void onHideCustomView() {
if (mCustomVideoView == null)
return;
// Hide the custom view.
mCustomVideoView.setVisibility(View.GONE);
// Remove the custom view from its container.
mCustomViewContainer.removeView(mCustomVideoView);
mCustomVideoView = null;
mCustomViewContainer.setVisibility(View.GONE);
mCustomViewCallback.onCustomViewHidden();
// Show the content view.
mContentView.setVisibility(View.VISIBLE);
}
@Override
public void onCompletion(MediaPlayer mp) {
mp.stop();
mCustomViewContainer.setVisibility(View.GONE);
onHideCustomView();
interfazWeb.setContentView(mContentView);
}
@Override
public boolean onError(MediaPlayer mp, int what, int extra) {
interfazWeb.setContentView(R.layout.main);
return true;
}
}
所以，这段代码很受android project source code of the browser启发。
而且，这样做的行为就是打开全屏视频。我不知道是否可以在网页内的自己的框架中播放视频。但是这个解决方案对我有用，我也希望你。
此致
