How to disable swipes in a view pager in android

2019-09-25 02:33发布

问题:

I am new to android. I am creating an app which consists of a view pager with a swipe tab layout. When I click the button it does some calculations inside of the view pager. While it's doing this I want the switching between the tabs to be disabled. So no swiping between the pages while it's calculating. After the calculations are completed I want the switching to be enabled again. Can anyone tell me how to do this please? Thanks in advance. I tried this. Please have a look at it:

    public class Auto extends FragmentActivity{
    Button tests;
    private ViewPager pager;
    @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.auto);
                tests = (PaperButton)findViewById(R.id.action_button_tests);
                tests.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        if(pager.getCurrentItem()==0){
                            tests.setTag(1);
                            tests.setText("START TEST");
                        final int status = (Integer)v.getTag();
                        if(status==1){
                            tests.setText("STOP TEST");
                            v.setTag(0);
                            int i;
                            Login.Communication_Ok=false;
                            for( i=0;(i<5 && Login.Communication_Ok!=true);i++)

回答1:

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;
} }

You just need to call the "setPagingEnabled" method with "false" and users won't be able to swipe to paginate.
