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 write below codes, but not work me and when click on TabLayout items, go to that fragment!

</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;
}
});
}
