ImageView에서 이미지 자동 변경

나는 이미지 뷰와 많은 이미지를 가지고 있지만 문제는 이미지 뷰의 모든 이미지를 차례로 표시하고 이미지가 gif 애니메이션처럼 매초 또는 0.2 초마다 변경되어야한다는 것입니다.

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="97dp"
    android:layout_marginTop="108dp"
    android:src="@drawable/ic_launcher" />



import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.webkit.CookieManager;
import android.webkit.WebSettings;
import android.webkit.WebSettings.PluginState;
import android.webkit.WebSettings.RenderPriority;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends Activity {


private WebView mWebView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    CookieManager.getInstance().setAcceptCookie(true);//Enable Cookies

    mWebView = (WebView) findViewById(R.id.webView1);
    mWebView.getSettings().setJavaScriptEnabled(true);//Enable Java Script
    mWebView.setWebViewClient(new HelloWebViewClient());
    mWebView.loadUrl("http://www.google.com/"); //Set Home page
    mWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);//Remove ScrollBars
    mWebView.getSettings().setDefaultFontSize(12);//Set Font Size
    mWebView.getSettings().setLoadsImagesAutomatically(true);//Enable Image Loading
    mWebView.getSettings().setPluginState(PluginState.ON);//Enable Flash
    mWebView.getSettings().setRenderPriority(RenderPriority.HIGH); //improves Feedback     on touch
    mWebView.setBackgroundColor(0x00000000);//Transparent Screen When Loading
  //mWebView.getSettings().setBuiltInZoomControls(true);//Set Zoom Controls 

    mWebView.getSettings().setAppCacheMaxSize(1024*1024*8);//Set Cache (8mb)
    String appCachePath =     getApplicationContext().getCacheDir().getAbsolutePath();//Set Cache (8mb)
    mWebView.getSettings().setAppCachePath(appCachePath);//Set Cache (8mb)
    mWebView.getSettings().setAllowFileAccess(true);//Set Cache (8mb)
    mWebView.getSettings().setAppCacheEnabled(true);//Set Cache (8mb)
    mWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);//Set Cache (8mb)

    mWebView.setWebViewClient(new WebViewClient() {//Show Image/Page/HTML on Error
    public void onReceivedError(WebView view, int errorCode, String description,     String failingUrl) {//Show Image/Page/HTML on Error
    mWebView.loadUrl("http://www.google.com");//Show WebPage on Error, to show     Offline file, use ("file:///android_asset/error_404.jpg");
        }
    });


}
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView webview, String url)
{


webview.loadUrl(url);
return true;
}
}

 @Override
 public boolean onKeyDown(int keyCode, KeyEvent event)
  {

 if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack())

{
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
