Perché si dice "Bitmap non può essere risolto in un tipo" in questo caso?

Question

Ho ricevuto questo errore. Come posso risolvere questo problema nella mia situazione?

"Bitmap cannot be resolved to a type" 

La linea in cui si verifica l'errore

public void onPageStarted(WebView view, String url, Bitmap favicon) { 

Il mio codice

public class MainActivity extends Activity { 
    private Activity activity = this; 
    private String title = ""; 

    private ActionBar mActionBar; 


    private SimpleSideDrawer mNav; 
    WebView myWebView; 

    int width, height; 
    float flick_width; 
    float flick_height;  

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

      title = activity.getTitle().toString(); // (1) 
      requestWindowFeature(Window.FEATURE_PROGRESS); 

     setContentView(R.layout.activity_main); 



     getSize(); 

     mActionBar = getActionBar(); 
     mActionBar.hide(); 


     mNav = new SimpleSideDrawer(this); 
     mNav.setLeftBehindContentView(R.layout.activity_behind_left_simple, this); 
     mNav.setRightBehindContentView(R.layout.activity_behind_right_simple, this); 


     myWebView = (WebView)findViewById(R.id.webView1); 
     myWebView.setWebViewClient(new WebViewClient()); 
     myWebView.getSettings().setJavaScriptEnabled(true); 

     myWebView.setWebViewClient(new WebViewClient() { 
      @Override 
      public void onPageStarted(WebView view, String url, Bitmap favicon) { 
       Log.d("HelloWebView", "onPageStarted : " + url); 
       activity.setTitle("Loading..."); // (2) 
       activity.setProgressBarVisibility(true); 
      } 
      @Override 
      public void onPageFinished(WebView view, String url) { 
       Log.d("HelloWebView", "onPageFinished : " + url); 
      } 
      @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       Log.d("HelloWebView", "shouldOverrideUrlLoading : " + url); 
       return super.shouldOverrideUrlLoading(view, url); 
      } 
      @Override 
      public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 
       Log.d("HelloWebView", "onReceivedError : "+description); 
       //view.loadData("Error "+description, "text/plain", "utf-8"); 
       view.loadDataWithBaseURL(null, "Error ("+errorCode+"):"+description, "text/plain", "utf-8", null); 
      } 
     }); 
     myWebView.setWebChromeClient(new WebChromeClient() { // (3) 
      public void onProgressChanged(WebView view, int progress) { 
       activity.setProgress(progress * 100); 
        Log.d("HelloWebView", "progress="+progress); 
        if (progress==100) { 
         activity.setProgressBarVisibility(false); 
         activity.setTitle(title); 
        } 
      } 
     }); 

     myWebView.loadUrl("http://yahoo.com");   
     myWebView.getSettings().setSupportZoom(true); 
     myWebView.getSettings().setLoadWithOverviewMode(true); 
     myWebView.getSettings().setUseWideViewPort(true); 

Answer 1

Eclipse volte singhiozzo quando si cerca di importazioni di auto-resolve. In casi come questo, puoi provare a inserire manualmente la dichiarazione di importazione: import android.graphics.Bitmap;

Answer 2

Fai semplicemente clic su "Ctr + Shift + O" anche se non mostra l'importazione quando ci si posiziona sopra ... lo importerà automaticamente quando si fare clic --- --- "Ctr + Shift + O"
