onfling

问题 In the Android Developers gesture design section, the term "swipe" is used. In the developer section, the term "fling" is used. Are these terms synonymous? From what I have found, I believe they are, but nowhere is it explicitly said one way or the other. That said, if I want to implement functionality for a "swipe," should I implement onFling in GestureDetector ? 回答1: onFling() will get executed when a user makes a "fling" motion, and said motion has a velocity with it to determine the type

问题 I tried implementing 2 finger swipe using onFling method of SimpleOnGestureListener . However,I found that SimpleOnGestureListener doesn't support two finger touch. How can I work it out ? 回答1: My Solution works, but its quite ugly to use a public static int to count how many fingers there are. i had to set fingercount back to one after i flinged with two fingers because i couldnot get the action_pointer_down for one finger anymore... i dont know why... but this solution would also work for

问题 I have a dialog to choose files from. This dialog contains a listview to show directories and files and has an onItemClickListener for navigation purposes. How can I react to fling events to go up in the directory structure? I tried setting an OnTouchListener on the root RelativeLayout to dispatches touch events to my GestureListener: final GestureDetector detector = new GestureDetector(new MyGestureDetector(tvCurrentPath)); dialog.findViewById(R.id.rlFilelist).setOnTouchListener(new

问题 Please help to solve this problem. I use implementation of OnGestureListener in TabActivity with overriding of method onFling for switching between tabs. But that doesn't work when one of my tabs is ListActivity. Thanks 回答1: Try adding the listener to ListView or yours ListActivity too. 来源： https://stackoverflow.com/questions/5116837/listactivity-inside-tabactivity

问题 I'm trying to detect an onFling event for a TextView object. The code below works perfectly for the onDown event, however it fails to get the onScroll or onFling events. Any pointers? Thanks package rob.testapp; import android.app.Activity; import android.os.Bundle; import android.view.GestureDetector; import android.view.GestureDetector.SimpleOnGestureListener; import android.view.MotionEvent; import android.view.View; import android.widget.TextView; public class MainActivity extends

问题 Expanding on another Stackoverflow question, I've implemented some gesture detection code so that I can detect when a row in my listview (which is in a FrameLayout) has been swiped. I followed the question/answer by Damian here about how to get the individual row/view from the adapter. How to get location (on screen) of row in listview I have code in my onFling that gets the view for the row, and tries to make a delete button that is set as invisible in my xml layout to visible. However, this

问题 I am trying to implement the OnGestureListener in Android. I have three TextViews in my layout. What i am trying to achieve is to set Gesture Listener for two of the textViews . Here is the layout - <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/rlMain" android:layout_width="wrap_content" android:layout_height="wrap_content" > <TextView android:id="@+id/tvOne" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout

问题 By looking at other posts here I've been able to get my WebView to respond to swipes - but with some problems. What I'm trying to accomplish is make a right-to-left swipe act just like the back button in my activity. This means sometimes calling webview.goBack or LoadURL to go to a previous page, or if I'm at the top webpage calling super.onBackPressed to close the current webview. The latter case works perfectly, but the browser controls are only partially working. If I open the webview and

问题 I would like to add a GestureDetector to all views (view groups) of an activity without assigning it manually to every single view. Right now onFling() is only activated when swiping over the background but not when swiping on e.g. button1. package com.app.example; import android.app.Activity; import android.content.Context; import android.graphics.Color; import android.os.Bundle; import android.util.Log; import android.view.GestureDetector; import android.view.MotionEvent; import android

问题 This is my first post on StackOverflow! I have a background service running and I was wondering if I could actually simulate a horizontal fling touch screen gesture instead of just detecting that it was been called. I can figure out how to capture this event, but I want to actually simulate a touch fling horizontal gesture instead of waiting for one. Thanks beforehand! 回答1: There is an API for simulating touch events. Some people report limited success simulating a fling using the TouchUtil
