好的,我在这里引用了代码:在网格布局上进行手势检测
但是无法让它发挥作用.在我的主要活动中,我定义了一个简单的图像.我想检测一下图像上的闪光.这是我的代码如下.底部的onclick方法为空.是因为这个吗？我把它留空了,因为在其他代码示例中它不是我想要的.我只想要一个简单的吐司,弹出正确的方向或向前扔.
public class GestureRightLeft extends Activity implements OnClickListener {
ImageView peek;
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;
private GestureDetector gestureDetector;
View.OnTouchListener gestureListener;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
peek =(ImageView) findViewById(R.id.peek);
peek.setImageResource(R.drawable.bluestrip);
gestureDetector = new GestureDetector(new MyGestureDetector());
gestureListener = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
if (gestureDetector.onTouchEvent(event)) {
return true;
}
return false;
}
};
}
class …ViewPager现在滚动的方式是每个手势一个项目.无论是全屏快速拖动还是慢速拖动,它都以同样的方式对待投掷手势; 在结束页面只前进一步.
是否有任何项目或示例可以添加基于速度的投掷,根据现有投掷的速度滚动多个项目(如果它仍在进行中)并且如果投掷手势宽而快,则进一步滚动？
如果没有从哪里开始这样的事情？
PS提供赏金.请不要回答对Gallery或HorizontalScrollView的引用
我正在尝试在Android中实现OnGestureListener.
我的布局中有三个TextView.
我想要实现的是为两个textView设置Gesture Listener.
这是布局 -
<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_centerHorizontal="true"
android:layout_marginBottom="10dp"
android:layout_marginTop="5dp"
android:gravity="center"
android:text="One" />
<TextView
android:id="@+id/tvTwo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/tvOne"
android:layout_centerHorizontal="true"
android:layout_marginBottom="10dp"
android:layout_marginTop="5dp"
android:gravity="center"
android:text="Two" />
<TextView
android:id="@+id/tvThree"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/tvTwo"
android:layout_centerHorizontal="true"
android:layout_marginBottom="10dp"
android:layout_marginTop="5dp"
android:gravity="center"
android:text="Three" />
这是活动 -

gestureScanner …我有一个包含大量内容的滚动视图.现在,当用户进行投掷或向下滚动时,我希望滚动视图停在特定的视图位置,我正在做一些动画,然后用户可以再次投掷或向下滚动.
我已尝试禁用此处提到的scrollview 但它只在scrollview完全停止并且无法在fling中间停止时禁用.
有什么办法可以在达到某个视图位置或某个y值时停止滚动视图的投掷？
我想检测屏幕块中的投掷动作.我正在使用以下代码.
public class MyinfoActivity extends Activity implements OnGestureListener {
@Override
public void onCreate(Bundle savedInstanceState) {

resBlock = (TableRow) findViewById(R.id.ResBlock);

if (gestureScanner.onTouchEvent(me))
return gestureScanner.onTouchEvent(me);
else
return false;

public class MainMenuSlider extends Activity implements OnClickListener{
protected MyGestureListener myGestureListener;
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;
private ViewFlipper vf;
private Animation animFlipInNext,animFlipOutNext, animFlipInPrevious, animFlipOutPrevious;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainmenuslider);
myGestureListener = new MyGestureListener(this);
//vf for viewflipper
vf=(ViewFlipper)findViewById(R.id.ViewFlipper01);
animFlipInNext = AnimationUtils.loadAnimation(this, R.anim.flipinnext);
animFlipOutNext = AnimationUtils.loadAnimation(this, R.anim.flipoutnext);
animFlipInPrevious = AnimationUtils.loadAnimation(this, R.anim.flipinprevious);
animFlipOutPrevious = AnimationUtils.loadAnimation(this, R.anim.flipoutprevious);
imageone = (ImageView) findViewById(R.id.imageone);
imagetwo = (ImageView) findViewById(R.id.imagetwo);
imageone.setOnClickListener(myGestureListener); …我已经覆盖ScrollView了将MotionEvents 传递给a GestureDetector来检测ScrollView上的fling事件.我需要能够检测到滚动停止的时间.这与MotionEvent.ACTION_UP事件不一致,因为这通常发生在fling手势的开始,随后onScrollChanged()是ScrollView上的一连串调用.
所以基本上我们在这里处理的是以下事件:
触发onScrollChanged事件时没有回调.我正在考虑使用HandleronFling期间向事件队列发送消息并等待Runnable执行以指示fling 结束,不幸的是它在第一次onScrollChanged调用之后触发.
还有其他想法吗？
我想将GestureDetector添加到活动的所有视图(视图组),而不是手动将其分配给每个视图.现在onFling()仅在向后滑动时激活,但在滑动例如button1时不激活.
