如何禁用Android中的TabLayout

问题描述

我想在我的应用程序中使用TabLayout来使用fragment和ViewPager.
但我要禁用，请单击TabLayout在fragment之间切换，只需滑动在fragmenst之间切换.
我写下面的代码，但对我不起作用，单击TabLayout项时，转到该fragment！

I want use TabLayout in my application for use fragment and ViewPager.
but I want disable click on TabLayout to switch between fragment, just swipe to switch between fragmenst.
I write below codes, but not work me and when click on TabLayout items, go to that fragment!

MainActivity XML:

            app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    </android.support.design.widget.CoordinatorLayout>

MainActivity java:

public class Main_Page extends AppCompatActivity {

    private CollapsingToolbarLayout mCollapsingToolbarLayout;
    private Toolbar toolbar;
    private TabLayout tabLayout;
    private ViewPager viewPager;

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

        mCollapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar_layout);
        //mCollapsingToolbarLayout.setTitle(getResources().getString(R.string.app_name));

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        //getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        viewPager = (ViewPager) findViewById(R.id.viewpager);
        setupViewPager(viewPager);

        tabLayout = (TabLayout) findViewById(R.id.tabs);
        LinearLayout tabStrip = ((LinearLayout)tabLayout.getChildAt(0));
        for(int i = 0; i < tabStrip.getChildCount(); i++) {
            tabStrip.getChildAt(i).setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    return true;
                }
            });
        }
        tabLayout.setupWithViewPager(viewPager);
        setupTabIcons();
    }

    /**
     * Adding custom view to tab
     */
    private void setupTabIcons() {

        TextView tabOne = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabOne.setText(R.string.free_fragment_title);
        tabOne.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_download_image, 0, 0);
        tabLayout.getTabAt(0).setCustomView(tabOne);

        TextView tabTwo = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabTwo.setText(R.string.paid_fragment_title);
        tabTwo.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_paid_download_image, 0, 0);
        tabLayout.getTabAt(1).setCustomView(tabTwo);

        TextView tabThree = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabThree.setText(R.string.pdf_fragment_title);
        tabThree.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_pdf_icon, 0, 0);
        tabLayout.getTabAt(2).setCustomView(tabThree);
    }

    /**
     * Adding fragments to ViewPager
     * @param viewPager
     */
    private void setupViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFrag(new free_fragment(), "رایگان ها");
        adapter.addFrag(new paid_fragment(), "پرداختی ها");
        adapter.addFrag(new pdf_fragment(), "مقالات");
        viewPager.setAdapter(adapter);
    }

    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

        @Override
        public Fragment getItem(int position) {
            return mFragmentList.get(position);
        }

        @Override
        public int getCount() {
            return mFragmentList.size();
        }

        public void addFrag(Fragment fragment, String title) {
            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);
        }
    }
}

要禁用，请点击TabLayout，我使用以下代码:

for disable click on TabLayout I use this code:

LinearLayout tabStrip = ((LinearLayout)tabLayout.getChildAt(0));
for(int i = 0; i < tabStrip.getChildCount(); i++) {
    tabStrip.getChildAt(i).setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return true;
        }
    });
}

我该如何解决这个问题?谢谢所有< 3

How can I solve this problem? Thanks all <3

推荐答案

您要在setupWithViewPager之前访问选项卡，这就是为什么您的代码无法正常工作的原因.因此，首先设置标签，然后设置touchlistener代码.

You are accessing tabs before setupWithViewPager, thats why your code is not working. So first set tabs then settouchlistener code.

尝试一下:

tabLayout.setupWithViewPager(viewPager);
    setupTabIcons();

LinearLayout tabStrip = ((LinearLayout)mTabLayout.getChildAt(0));
    for(int i = 0; i < tabStrip.getChildCount(); i++) {
        tabStrip.getChildAt(i).setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                return true;
            }
        });
    }
