I'm new with Android development. I got trouble using SwipeToRefresh option in WebView. I'm trying to solve it from a mounth now and after trying several codes, it's not working. Also Youtube video is not playing in full screen from the WebView...
Here's my question: How to hide SwipeToRefresh ProgressBar and stop running?
Here is my MainActivity class:
public class WebViewActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
private WebView myWebView;
private SwipeRefreshLayout mSwipeRefreshLayout;
//HTML5 video
private View mCustomView;
private int mOriginalSystemUiVisibility;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
OneSignal.startInit(this)
.setNotificationOpenedHandler(new ExampleNotificationOpenedHandler())
.init();
setContentView(R.layout.activity_web_view);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
MobileAds.initialize(getApplicationContext(), "ca-app-pub-App Id");
AdView mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
//WebView
mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.refreshlayout);
myWebView = (WebView) findViewById(R.id.webview);
mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
myWebViewSettings();
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
//improve webView performance
myWebView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
myWebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
myWebView.getSettings().setAppCacheEnabled(true);
myWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webSettings.setDomStorageEnabled(true);
webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
webSettings.setUseWideViewPort(true);
webSettings.setSavePassword(true);
webSettings.setSaveFormData(true);
webSettings.setEnableSmoothTransition(true);
myWebView.loadUrl("http://www.youtube.com");
//force links open in webview only
myWebView.reload(); // refreshes the WebView
}
});
myWebView.setWebViewClient(new MyWebViewClient());
}
