Android 如何在视图的特定方面激活onTouchEvent（）运动？

例如，我的一个XML文件中有一个scrollView和一个LinearLayout。LinearLayout是屏幕底部的一个小条，用作导航（70dp高）

我想这样做，如果用户在该线性布局中向上/向下滑动，它将在其下方显示另一个线性布局。有点像一个扩展菜单

我已经创建并放置了扩展布局，动画正在运行。但我无法让它在线性布局内上下滑动

我该怎么做？提前谢谢

编辑：代码示例

这是XML的一个示例

<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/wv"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_above="@+id/llSM"
    />
<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="70dp"
        android:id="@+id/llSM"
        android:orientation="horizontal"
        android:layout_above="@+id/llNav"
        android:layout_alignWithParentIfMissing="true"
        >

        <ImageButton
            android:id="@+id/bWebsite"
            android:layout_width="70dp"
            android:layout_height="70dp"
            android:src="@drawable/nhome"
            android:clickable="true"
            android:scaleType="fitXY"

            android:layout_weight="1" />

        <ImageButton

            android:layout_width="70dp"
            android:layout_height="70dp"
            android:src="@drawable/nhome"
            android:clickable="true"
            android:scaleType="fitXY"
            android:background="#FFFFFF"
            android:layout_weight="1" />

        <ImageButton

            android:background="#FFFFFF"
            android:layout_weight="1" />
</LinearLayout>
<LinearLayout
    android:id="@+id/llNav"
    android:layout_width="match_parent"
    android:layout_height="70dp"
    android:orientation="horizontal"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="false"
    android:layout_alignParentTop="false"
    android:layout_centerInParent="true"
    android:gravity="bottom|center_horizontal"
    >

    <ImageButton
        android:id="@+id/bHome"
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:src="@drawable/nhome"
        android:clickable="true"
        android:scaleType="fitXY"
        android:background="#FFFFFF"
        android:layout_weight="1"
        />

    <ImageButton
        android:id="@+id/bContact"
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:src="@drawable/ncontactus"
        android:clickable="true"
        android:layout_toRightOf="@+id/bHome"
        android:background="#FFFFFF"
        android:scaleType="fitXY"
        android:layout_weight="1"
        />

    <ImageButton
        android:id="@+id/bBooking"
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:src="@drawable/onlinebooking"
        android:clickable="true"
        android:layout_toRightOf="@+id/bContact"
        android:background="#FFFFFF"
        android:scaleType="fitXY"
        android:layout_weight="1"
        />
</LinearLayout>

这是一个主要的例子：

protected void onCreate(Bundle savedInstanceState) {
    //Remove title bar
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_external);

    ll = (LinearLayout) findViewById(R.id.llNav);
    ll.setVisibility(View.GONE);

    animUp = AnimationUtils.loadAnimation(this, R.anim.anim_up);
    animDown = AnimationUtils.loadAnimation(this, R.anim.anim_down);

    NavBar(); //This just loads the buttons and their intents
    Links(); //This is for the second linear layout loading social media
    myWebView.setWebViewClient(new WebViewClient());
    myWebView.getSettings().setJavaScriptEnabled(true);
    myWebView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
    myWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
    myWebView.loadUrl("url");


    ll2 = (LinearLayout) findViewById(R.id.llSM);

    ll2.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_DOWN){
                startY = event.getY();
                //hello you just touched me!!!
            } else if(event.getAction() == MotionEvent.ACTION_UP) {
                float endY = event.getY();
                if ((endY < startY) && (a==0)) {
                    ll.setVisibility(View.VISIBLE);
                    ll.startAnimation(animUp);
                    a = a+1;
                }
                else {
                    if ((endY > startY) && (a>=1)){
                        ll.startAnimation(animDown);
                        ll.setVisibility(View.GONE);
                        a = 0;
                    }
                }
            }


            return false;
        }
    });

}

创建时受保护的void（Bundle savedInstanceState）{
//删除标题栏
this.requestWindowFeature（Window.FEATURE\u NO\u TITLE）；
super.onCreate（savedInstanceState）；
setContentView（R.layout.activity_外部）；
ll=（线性布局）findViewById（R.id.llNav）；
ll.setVisibility（View.GONE）；
animUp=AnimationUtils.loadAnimation（this，R.anim.anim\u up）；
animtown=AnimationUtils.loadAnimation（this，R.anim.anim\u down）；
NavBar（）；//这只是加载按钮及其意图
Links（）；//这是加载社交媒体的第二个线性布局
setWebViewClient（新的WebViewClient（））；
myWebView.getSettings（）.setJavaScriptEnabled（true）；
myWebView.getSettings（）.setRenderPriority（WebSettings.RenderPriority.HIGH）；
myWebView.getSettings（）.setCacheMode（WebSettings.LOAD\u NO\u缓存）；
myWebView.loadUrl（“url”）；
ll2=（线性布局）findViewById（R.id.llSM）；
ll2.setOnTouchListener（新视图.OnTouchListener（）{
@凌驾
公共布尔onTouch（视图v，运动事件）{
if（event.getAction（）==MotionEvent.ACTION\u向下）{
startY=event.getY（）；
//你好，你刚刚碰了我！！！
}else if（event.getAction（）==MotionEvent.ACTION\u UP）{
float endY=event.getY（）；
如果（（endYstartY）和&（a>=1））{
ll.startAnimation（animDown）；
ll.setVisibility（View.GONE）；
a=0；
}
}
}
返回false；
}
});
}

WebView在其中滚动，因此无法在其中工作。我希望能够在标有“llSM”的线性布局上滑动，以打开其下方的“llNav”栏，并将所有内容向上推。我还需要单击“llSM”栏上的按钮以在不同的web视图之间导航。

您所说的

线性布局是一个
视图
+组，因此在其上调用
视图。ontouch Listener

thatParticularLinearLayout.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
    if(event.getAction() == MotionEvent.ACTION_DOWN){

        //hello you just touched me!!! 
        return true;
    }
    return false;
  }
});

您的代码很棒，先生，但是android中有一个叫做
OnInterceptouchevent（）
的东西非常适合您的情况，就像我说的linearLayout-（llSM和llNav）是一个
视图组，所以您可以调用
OnInterceptouchevent（）
让它在孩子们看到之前拦截所有触摸事件。。维护您的触摸事件代码

好的，在这里，他们甚至有代码示例来支持您

好的，根据您的需要尝试扩展
ViewFlipper
我喜欢它，它很棒。或者
viewmanimator
它们将使您的工作变得轻松。。让我们看看

   public class Noodles extends ViewFlipper { // for your situation i will say extend this.. i am not saying this is
// the only way but that's the best and easiest i can think of..
// this viewgroup will be in a viewgroup maybe linear layout.. but those child linearlayout
// declare them like in different layouts okay..

Context context;// context to use
boolean intercept; // i dont know if i will use this but to indicate if it will intercept
View[] children;
float inx,iny = (float) 0.000; // this is the touched position that will be captured in on down in your touch
// i am not a OMG mathmatician but if you equate it to 0, its allways going to fail.. so the number of infinity
// depends on you.d thats just btw, so try it and see maybe i might be wrong

public Noodles(Context context,View[] children/* or LinearLayout[] children*/) { // construtor.. with the child layouts 
    super(context);     
    this.context = context;
    this.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); // setting params..
    this.setInAnimation(AnimationUtils.loadAnimation(context, someSickAnimationThatwILLSlidInFromTop)); // the animation should follow the pattern like this "R.anim.abc_slide_in_top" this is a default in animation
     /// but the spelling might differ
    this.setOutAnimation(AnimationUtils.loadAnimation(context, someSickAnimationThatwILLSlidOutFromTop));
    this.children = children;
    for(int i=0;i<children.length;i++){
        this.addView(children[i]);
    }
}

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {

    // here you can use math catch the movement, something like 0,0 [x,y];
    // get the point loaction at with it was touched
    // when y increases it is coming down, when it decresse it is going up - all in respect to the intial
    // point.. you can intercept when y increase by a set of marging lets say like 20..or 10, because
    // eventually x will increase as is it is not straight line..but i can not rilly say, because i am conjuring from how it worksk,maybe im right maybe i am not   
    if(ev.getAction() == MotionEvent.ACTION_DOWN){
        Log.v("Noodles", "triggered");
        intercept = false;
    }
    if(ev.getAction() == MotionEvent.ACTION_MOVE){
        Log.v("Noodles", "noodles intercept fired"); 
        intercept = true;

        return true;
    }

        if(intercept)  // yes i do 
            return true;
    }
    Log.v("Noodles", "noodles intercept ignored");
    return false;
}

@Override
public boolean onTouchEvent(MotionEvent ev) {

    // i think you can do the calculation 
    // to know if its going up or down respectively
    // use this.showNext(); for showing the next item from bottom to top the this.showPrevious vice versa
    Log.v("Noodles", "noodles touch fired");
    //i am trying the calculation, use and see if it works
    float inx,iny = 0;
    if(ev.getAction() == MotionEvent.ACTION_DOWN){
        Log.v("touchy", "triggered");
        iny = ev.getY();
        inx = ev.getX();
        Log.v("touchy", "x : " +String.valueOf(inx));
        Log.v("touchy", "y : " +String.valueOf(iny));
    }

    if(ev.getAction() == MotionEvent.ACTION_MOVE){
        int retval = Float.compare(iny, ev.getY());

        if(retval > 0){
            //noodles i am goin up 
            // this flips the current view out with upward movement animation you declared the in
            Log.v("touchy", "i am going up"); 
        }else if(retval < 0){
            // noodles i am goin down
            // this flips the current view out with downward movement
            Log.v("touchy", "i am going down");
        }
        // you can put your animations in their respective statements and rememba to call this.showNext(); in the upward movement and this.ShowPrevious(); the other

        Log.v("touchy", "y : " +String.valueOf(iny));
        return true;

    if(ev.getAction() == MotionEvent.ACTION_UP){

如果您复制并粘贴此内容，您可能会看到一些不寻常的错误，请更正它们，好吧，因为它们非常丰满，我想当我使用笔记本电脑时，我会更正它们以备将来使用

如果有帮助，请告诉我。
我只是尝试实现此功能，但没有成功：（可能是因为linearlayout中有图像按钮吗？我将用代码编辑上面的帖子。添加了代码。我可能做了所有错事，因为我是Android新手。谢谢你的帮助！哦，好的，那么llsm和llnav都将收到此刷击，对吗？好的，请稍候up@Noodelzi已经编辑了它，并且包含了有代码帮助的链接你的案例如果你仍然觉得无聊，那么当我很空闲的时候，我会做代码@Noodelz，抱歉耽搁了，先生，事情发生了这么多！我会试试看，看看我会怎么做：）如果我不能让它工作，那么我可能会回来哈哈。你自己尝试一下+1
// in your actvity instatiate it
Noodles n = new Noodles(this,View1,View2); 
// then add it to your parent view or your layout that is to be your navigation
