Question

这是我的viewPager代码。我想禁用用户在viewPager之间滑动但能够点击它。

这是我的代码;

        vp= (ViewPager)header.findViewById(R.id.pager); 
    vp.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return true;
        }
    });

    vp.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent in=new Intent (FistActiivty.this,List.class);
            in.putExtra("for","latest");
            startActivity(in);              
        }
    });

它禁止用户滑动，但之后onclicklistener无效。

如何让onclicklistener再次运行但禁用用户滑动？

您需要创建像此一样扩展ViewPager的自定义类

MyViewPager.java

public class MyViewPager extends ViewPager 
{
    public MyViewPager(Context context) 
    {
        super(context);
    }

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

    @Override
    public boolean onInterceptTouchEvent(MotionEvent arg0) {
        // Never allow swiping to switch between pages
        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // Never allow swiping to switch between pages
        return false;
    }

}

其次，你需要在xml中进行一次更改，你已经定义了android.support.v4.view.ViewPager

喜欢这个

<YourProjectPackageName.MyViewPager
        android:id="@+id/viewPager"
        android:layout_width="fill_parent"
        android:layout_height="match_parent" />

创建自定义viewpager类：

public class CustomViewPager extends ViewPager {

private boolean enabled;

public CustomViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
    this.enabled = true;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (this.enabled) {
    return super.onTouchEvent(event);
}

return false;
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onInterceptTouchEvent(event);
    }

    return false;
}

public void setPagingEnabled(boolean enabled) {
    this.enabled = enabled;
}
}

并将其用于您的xml文件：

<mypackage.CustomViewPager 
android:id="@+id/myViewPager" 
android:layout_height="match_parent" 
android:layout_width="match_parent" />

我正在使用它。您需要致电viewPager.setPagingEnabled(false);

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;

/**

public class CustomViewPager extends ViewPager {

    private boolean enabled = true;

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

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

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return !enabled || super.onTouchEvent(event);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        return enabled && super.onInterceptTouchEvent(event);
    }

    public void setPagingEnabled(boolean enabled) {
        this.enabled = enabled;
    }
}
