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

public class CalculatorViewPager extends ViewPager {
    private boolean enabled;
    public CalculatorViewPager(Context context) {
        super(context);
        this.enabled = false;
    }   

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

    public boolean shouldDelayChildPressedState() {
        return false;

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

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        if (this.enabled) {
            return super.onInterceptTouchEvent(event);
        }
        android.util.Log.e("zhangshuli", "paninter");
        return false;
    }   

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