Question

我正面臨從webview調用android Admob插頁式廣告的問題。我無法得到任何適當的解決方案。最後，我想出瞭解決方案來調用JavaScript的插頁式廣告。看看下面的答案。

Answer 1

上述問題的解決方案
導入所有需要的軟件包。

public class MainActivity extends AppCompatActivity { 
    WebView myWevView; 
    public InterstitialAd mInterstitialAd; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     getSupportActionBar().hide(); 
     setContentView(R.layout.activity_main); 

     myWevView =(WebView)findViewById(R.id.myWevView); 
     WebSettings ws= myWevView.getSettings(); 
     ws.setJavaScriptEnabled(true); 
     ws.setDomStorageEnabled(true); 
     myWevView.getSettings().setUseWideViewPort(true); 
     myWevView.addJavascriptInterface(new WebAppInterface(this), "Android"); 
     myWevView.setWebViewClient(new WebViewClient()); 
     myWevView.setWebChromeClient(new WebChromeClient()); 
     myWevView.getSettings().setBuiltInZoomControls(true); 
     myWevView.loadUrl("file:///android_asset/index.html"); 
     mInterstitialAd = new InterstitialAd(this); 
     mInterstitialAd.setAdUnitId("ca-app-pub-3940256099942544/1033173712"); 
     mInterstitialAd.loadAd(new AdRequest.Builder().build()); 
     mInterstitialAd.setAdListener(new AdListener(){ 
     @Override 
      public void onAdLoaded(){ 

      } 
      @Override 
      public void onAdClosed() { 
       // Load the next interstitial. 
       mInterstitialAd.loadAd(new AdRequest.Builder().build()); 
      } 
     }); 

     } 




    public void displayLoadedAd(){ 
     runOnUiThread(new Runnable() { 
      public void run() { 
       if (mInterstitialAd.isLoaded()) { 
        mInterstitialAd.show(); 
        mInterstitialAd.loadAd(new AdRequest.Builder().build()); 
       } 
       else 
        Toast.makeText(getApplicationContext(), "Ad not loded", Toast.LENGTH_SHORT).show(); 
      } 

     }); 


    } 


    public class WebAppInterface { 
     Context mContext; 
     /** Instantiate the interface and set the context */ 
     WebAppInterface(Context c) { 
      mContext = c; 
     } 
     @JavascriptInterface 
     public void showAdFromJs(){ 

      Toast.makeText(mContext, "Loading Ad", Toast.LENGTH_SHORT).show(); 
       displayLoadedAd(); 
     } 
    } 
    //Controlling navigation 
    @Override 
    public boolean onKeyDown(int keyCode, KeyEvent event) { 
     if (event.getAction() == KeyEvent.ACTION_DOWN) { 
      switch (keyCode) { 
       case KeyEvent.KEYCODE_BACK: 
        if (myWevView.canGoBack()) { 
         myWevView.goBack(); 
        } 
        else { 
         finish(); 
        } 
        return true; 
      } 
     } 
     return super.onKeyDown(keyCode, event); 
    } 
} 

從JavaScript

$("#btn1").click(function(){ 
    Android.showAdFromJs(); 
}); 

Answer 2

我用這個沒有這樣的JavaScript調用呼叫：

@Override 
      public void onAdLoaded(){ 
       displayLoadedAd(); 

      } 

您需要將插頁式廣告的數量降低到你的優先。在你的admob控制檯中。
