This is my Code i have done both SWIPING and ZOOM IN and ZOOM OUT functions. But both doesnt worked in my app inside webview.
My problem is, If i do comment this line, then Swiping works fine !
webSettings.setBuiltInZoomControls(true);
If i don't comment this above line, then Zoom In and Out is working fine but swiping does not works here !
public class ZoomInandOutActivity extends Activity { private GestureDetector gestureDetector; WebView webviewSwiping; WebSettings webSettings; String data1 = "<html>" + "<body><h1>Hello, Android Aspect!</h1></body>" + "</html>"; String data2 = "<html>" + "<body><h1>Hellos, Android Aspectz!</h1></body>" + "</html>"; /* The Minimum distance a finger must travel in order to register a swipe event */ private static final int SWIPE_MIN_DISTANCE = 120; private static final int SWIPE_MAX_OFF_PATH = 250; private static final int SWIPE_THRESHOLD_VELOCITY = 200; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); webviewSwiping=new WebView(this); webSettings =webviewSwiping.getSettings(); webviewSwiping.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { return gestureDetector.onTouchEvent(event); } }); webSettings.setJavaScriptEnabled(true); webSettings.setBuiltInZoomControls(true); // used for Zooming and scrolling /* Gesture Detection */ gestureDetector=new GestureDetector(this, new MyGestureDetector()); setContentView(webviewSwiping); } class MyGestureDetector extends SimpleOnGestureListener{ @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { try { if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) return false; /* right to left swipe*/ if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { webviewSwiping.loadData(data1, "text/html", "UTF-8"); Toast.makeText(ZoomInandOutActivity.this, "Left Swipe", Toast.LENGTH_LONG).show(); } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { webviewSwiping.loadData(data2, "text/html", "UTF-8"); Toast.makeText(ZoomInandOutActivity.this, "Right Swipe", Toast.LENGTH_LONG).show(); } } catch (Exception e) { // nothing } return false; } }What i wanted is, If i do left or right swipe at that time zoom in and out should not work. If i do Zoom in and out those webview contents at that time left and right swiping must not work.
Like, When i do enable Swiping, Zooming must be disabled and when i do Zooming enabled at this time Swiping event must be disabled !
Moreover, I have a doubt that can i be able to achieve this both events inside webview by using setBuiltInZoom controls in Android 2.2 ?
How shall i achieve this both events in webview??
Please kindly anyone help me !
Any help or suggestions would be highly appreciated, thanks !
