import android.app.ProgressDialog; 
 
import android.support.v7.app.AppCompatActivity; 
 
import android.os.Bundle; 
 
import android.webkit.WebView; 
 
import android.webkit.WebViewClient; 
 
import android.widget.Toast; 
 

 
public class MainActivity extends AppCompatActivity { 
 

 
    WebView webView; 
 

 
    @Override 
 
    protected void onCreate(Bundle savedInstanceState) { 
 
     super.onCreate(savedInstanceState); 
 
     setContentView(R.layout.activity_main); 
 

 
     webView = (WebView) findViewById(R.id.webView); 
 
     webView.getSettings().setJavaScriptEnabled(true); 
 
     webView.getSettings().setSupportZoom(true); 
 
     webView.getSettings().setBuiltInZoomControls(true); 
 
     webView.loadUrl("http://youtube.com"); 
 

 

 
     final ProgressDialog progressDialog=ProgressDialog.show(this, "Mobil Video İzle", "Bağlantınız Kontrol Ediliyor", true); 
 
     progressDialog.show(); 
 

 
     webView.setWebViewClient(new WebViewClient() { 
 
      @Override 
 
      public void onPageFinished(WebView view, String url) { 
 
       super.onPageFinished(view, url); 
 
       Toast.makeText(MainActivity.this, "", Toast.LENGTH_SHORT).show(); 
 
       progressDialog.dismiss(); 
 
      } 
 

 
      @Override 
 
      public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 
 
       super.onReceivedError(view, errorCode, description, failingUrl); 
 

 
       Toast.makeText(MainActivity.this, "Bir hata oluştur!", Toast.LENGTH_SHORT); 
 
       progressDialog.dismiss(); 
 
      } 
 
     }); 
 

 

 
    } 
 
}

activity_main.xml 
 

 
    <?xml version="1.0" encoding="utf-8"?> 
 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 
    xmlns:tools="http://schemas.android.com/tools" 
 
    android:id="@+id/activity_main" 
 
    android:layout_width="match_parent" 
 
    android:layout_height="match_parent" 
 
    tools:context="net.aniplus.aniplus.MainActivity"> 
 

 
    <WebView 
 
     android:layout_width="match_parent" 
 
     android:layout_height="match_parent" 
 
     android:id="@+id/webView" /> 
 
</RelativeLayout> 
 

我想了几个小时，但我没有得到它的工作:(

在Android清单更改或添加活动的主题。

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
