先上代码吧

public class MainActivity extends AppCompatActivity { static final String iframeStr = ""; private WebView videoWebView; private FrameLayout fullScreenView; private View customView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); fullScreenView = (FrameLayout) findViewById(R.id.video_fullscreen); videoWebView = (WebView) findViewById(R.id.webView); WebSettings settings = videoWebView.getSettings(); settings.setJavaScriptEnabled(true); settings.setJavaScriptCanOpenWindowsAutomatically(true); settings.setDatabaseEnabled(true); settings.setAppCacheEnabled(true); settings.setCacheMode(WebSettings.LOAD_DEFAULT); settings.setPluginState(WebSettings.PluginState.ON); settings.setAllowFileAccess(true); settings.setLoadWithOverviewMode(true); settings.setDomStorageEnabled(true); settings.setUseWideViewPort(true); videoWebView.setWebChromeClient(new MyWebChromeClient()); videoWebView.setWebViewClient(new MyWebViewClient()); videoWebView.loadData(iframeStr,"text/html","utf-8"); } class MyWebViewClient extends WebViewClient{ @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { return false; } } class MyWebChromeClient extends WebChromeClient{ private CustomViewCallback customViewCallback; @Override public void onShowCustomView(View view, CustomViewCallback callback) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); videoWebView.setVisibility(View.INVISIBLE); // 如果一个视图已经存在，那么立刻终止并新建一个 if (customView != null) { callback.onCustomViewHidden(); return; } fullScreenView.addView(view); customView = view; customViewCallback = callback; fullScreenView.setVisibility(View.VISIBLE); } @Override public void onHideCustomView() { if (customView == null)// 不是全屏播放状态 return; setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); customView.setVisibility(View.GONE); fullScreenView.removeView(customView); customView = null; fullScreenView.setVisibility(View.GONE); customViewCallback.onCustomViewHidden(); videoWebView.setVisibility(View.VISIBLE); } } @Override protected void onResume() { super.onResume(); if (getRequestedOrientation() != ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); } videoWebView.resumeTimers(); } @Override protected void onPause() { super.onPause(); videoWebView.pauseTimers(); } @Override protected void onDestroy() { super.onDestroy(); videoWebView.destroy(); } }

就是用一个webview显示一个视频（不是一个视频网页，只是一个视频）,然后我使用的是iframe的链接（就是腾讯视频分享那里的通用代码）。我参照了网上很多关于全屏显示的问题，基本代码都是这样，但是并没有用，感觉没有调用到那两个函数。还有是不是跟链接里限定了大小有关系。这样的话，需要修改什么才能全屏呢？
