问题描述

我有一个viewpager刷卡左/ right.In我的第二个选项卡时,卡之间切换,我有有监听捏和拖动,但是当我试着捏或拖累,viewpager开始刷页面的一些自定义视图

一个解决方案,在我脑海是禁用当那些views.Is外界接触接触这些具体的意见,只有刷卡时,刷卡可以吗?

更新:@Asok好心提供的解决方案。但随后更新了code这wouldnt在我的情况下工作,所以我张贴previous一张code的工作对我来说:

 公共类CustomViewPager扩展ViewPager {
私人布尔swipeable = TRUE;

公共CustomViewPager(上下文的背景下){
    超(上下文);
}

公共CustomViewPager(上下文的背景下,ATTRS的AttributeSet){
    超(背景下,ATTRS);
}

//你的移动事件调用此方法时要禁用或启用
//它应该根据需要。
公共无效setSwipeable(布尔swipeable){
    this.swipeable = swipeable;
}

@覆盖
公共布尔onInterceptTouchEvent(MotionEvent为arg0){
    返程(this.swipeable)? super.onInterceptTouchEvent(arg0中):假的;
}
 

让我们假设我有一个可拖动的观点,我需要禁用swipping拖动时开始,并重新在拖放完成如此的TouchEvent使我所谓的观点:

  @覆盖
公共布尔的onTouchEvent(MotionEvent事件){
    开关(event.getAction()){
    案例MotionEvent.ACTION_DOWN:
//当触摸按钮禁用刷卡
((ActivityOriginal)getActivity())setSwipeable(假)。
//的code休息...
        打破;
    案例MotionEvent.ACTION_MOVE:

        打破;
    案例MotionEvent.ACTION_UP:
//重新启用swipping当触摸停止
//的code休息...
((ActivityOriginal)getActivity())setSwipeable(真)。
        打破;
    }
    返回true;
}
 

解决方案

想到的,我是有一个自定义的 ViewPager 这第一件事,当你触摸听众得到通知的特定事件,你可以设置 swipeable 布尔 ViewPager 为false,并设置回真哪个方式最适合你的应用程序。

 公共类CustomViewPager扩展ViewPager {
    私人布尔swipeable = TRUE;

    公共CustomViewPager(上下文的背景下){
        超(上下文);
    }

    公共CustomViewPager(上下文的背景下,ATTRS的AttributeSet){
        超(背景下,ATTRS);
    }

    //你的移动事件调用此方法时要禁用或启用
    //它应该根据需要。
    公共无效setSwipeable(布尔swipeable){
        this.swipeable = swipeable;
    }

    @覆盖
    公共布尔onInterceptTouchEvent(MotionEvent为arg0){
        返程(this.swipeable)? super.onInterceptTouchEvent(arg0中):假的;
    }

}
 


请一定要改变你的布局文件显示:

 < com.your.package.CustomViewPager .. />
 

相反的:

 < android.support.v4.view.ViewPager .. />

下面是我的设置(与工作上面 CustomViewPager ):

  CustomViewPager mViewPager;

@覆盖
保护无效的onCreate(包savedInstanceState){
    super.onCreate(savedInstanceState);
    的setContentView(R.layout.activity_main);

    //设置操作栏。
    最后的动作条动作条= getActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    //创建将返回一个片段为三个的适配器
    //应用程序的主要部分。
    mSectionsPagerAdapter =新SectionsPagerAdapter(getSupportFragmentManager());

    //设置的CustomViewPager与部分适配器。
    mViewPager =(CustomViewPager)findViewById(R.id.pager);
    mViewPager.setAdapter(mSectionsPagerAdapter);
    mViewPager.setOnPageChangeListener(新ViewPager.SimpleOnPageChangeListener(){
        @覆盖
        公共无效onPageSelected(INT位置){
            actionBar.setSelectedNavigationItem(位置);
        }
    });

    //对于每个应用程序的章节中,添加一个标签,操作栏。
    的for(int i = 0; I< mSectionsPagerAdapter.getCount();我++){
        actionBar.addTab(actionBar.newTab()
                .setText(mSectionsPagerAdapter.getPageTitle(I))
                .setTabListener(本));
    }

}

公共无效swipeOn(视图v){
    mViewPager.setSwipeable(真正的);
}

公共无效swipeOff(视图v){
    mViewPager.setSwipeable(假);
}
 

上面显示的onCreate 在我的 MainActivity 类,它扩展了 FragmentActivity 和农具 ActionBar.TabListener

I have a viewpager which switches between tabs when swiping left/right.In my second tab, i have some custom views which have listeners for pinching and dragging but when i try to pinch or drag, the viewpager starts to swipe the page.

A solution comes to my mind is to disable swiping when touching those specific views and only swipe when touching outside those views.Is this possible?

Updated:@Asok kindly provided the solution. But then updated the code which wouldnt work in my case so i post the previous piece of code which worked for me:

public class CustomViewPager extends ViewPager {
private boolean swipeable = true;

public CustomViewPager(Context context) {
    super(context);
}

public CustomViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
}

// Call this method in your motion events when you want to disable or enable
// It should work as desired.
public void setSwipeable(boolean swipeable) {
    this.swipeable = swipeable;
}

@Override
public boolean onInterceptTouchEvent(MotionEvent arg0) {
    return (this.swipeable) ? super.onInterceptTouchEvent(arg0) : false;
}

Lets suppose i have a draggable view and i need to disable swipping when dragging start and re enable when dragging finished so in TouchEvent of my so called view:

    @Override
public boolean onTouchEvent(MotionEvent event) {
    switch(event.getAction()) {
    case MotionEvent.ACTION_DOWN:
//disable swiping when the button is touched
((ActivityOriginal) getActivity()).setSwipeable(false);
//the rest of the code...
        break;
    case MotionEvent.ACTION_MOVE:

        break;
    case MotionEvent.ACTION_UP:
//re enable swipping when the touch is stopped
//the rest of the code...
((ActivityOriginal) getActivity()).setSwipeable(true);
        break;
    }
    return true;
}
解决方案

This first thing that comes to mind for me is to have a custom ViewPager in which, when your touch listeners get notified of a specific event you could set the swipeable boolean in ViewPager to false and set it back to true whichever way best fits your application.

public class CustomViewPager extends ViewPager {
    private boolean swipeable = true;

    public CustomViewPager(Context context) {
        super(context);
    }

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    // Call this method in your motion events when you want to disable or enable
    // It should work as desired.
    public void setSwipeable(boolean swipeable) {
        this.swipeable = swipeable;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent arg0) {
        return (this.swipeable) ? super.onInterceptTouchEvent(arg0) : false;
    }

}


Make sure to change your layout file to show:

<com.your.package.CustomViewPager .. />

Instead of:

<android.support.v4.view.ViewPager .. />


Edit 2

Here is my setup (Working with the above CustomViewPager):

CustomViewPager mViewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Set up the action bar.
    final ActionBar actionBar = getActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    // Create the adapter that will return a fragment for each of the three
    // primary sections of the app.
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());

    // Set up the CustomViewPager with the sections adapter.
    mViewPager = (CustomViewPager) findViewById(R.id.pager);
    mViewPager.setAdapter(mSectionsPagerAdapter);
    mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
        @Override
        public void onPageSelected(int position) {
            actionBar.setSelectedNavigationItem(position);
        }
    });

    // For each of the sections in the app, add a tab to the action bar.
    for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
        actionBar.addTab(actionBar.newTab()
                .setText(mSectionsPagerAdapter.getPageTitle(i))
                .setTabListener(this));
    }

}

public void swipeOn(View v) {
    mViewPager.setSwipeable(true);
}

public void swipeOff(View v) {
    mViewPager.setSwipeable(false);
}

The above shown onCreate is in my MainActivity class which extends FragmentActivity and implements ActionBar.TabListener
