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. */@Overridepublic 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 !
