I've created a small Activity which is capable of loading two different HTML strings in a webview. When I run the Activity it starts by loading the String from the page_1 variable. So far so good. The page shows as expected. I've added an onFling listener which should make the activity load the content of the page_2 variable. The problem is that even though the onFling is called and the loadUrl is called the webview isn't updated?
My activity looks like this:
import android.app.Activity;
import android.os.Bundle;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.webkit.WebView;
public class Test extends Activity {
private GestureDetector mGestureDetector;
private WebView mWebView;
private int mPageIndex;
private static final String page_1 = "<html><body>Hello page 1</body></html>";
private static final String page_2 = "<html><body>Hello page 2</body></html>";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.loadData(page_1, "text/html", "utf-8");
setupGestureDetection();
mPageIndex = 0;
}
private void setupGestureDetection() {
mGestureDetector = new GestureDetector(new MyGestureDetector());
mWebView.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
return mGestureDetector.onTouchEvent(event);
}
});
}
class MyGestureDetector extends GestureDetector.SimpleOnGestureListener {
private static final int SWIPE_DISTANCE_THRESHOLD = 120;
private static final int SWIPE_VELOCITY_THRESHOLD = 200;
private boolean isHorizontalSwipe(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
if (Math.abs(velocityX) > SWIP
