如何在Android中禁用对TabLayout的单击？
提问于 2016-06-14 10:33:46
我希望在我的应用程序中使用TabLayout，以便使用fragment和ViewPager。
但是我想禁用单击TabLayout在fragment之间切换，只是滑动以在fragmenst之间切换。
我写下面的代码，但不工作我和当点击TabLayout项目，去那个fragment！
MainActivity XML :
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="@string/app_namefull"
android:textSize="23sp" />
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="72dp"
app:tabGravity="fill"
app:tabIndicatorColor="@color/white"
app:tabMode="fixed" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
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);
}
}
}对于禁用单击TabLayout，我使用以下代码：
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？谢谢大家<3

您正在访问setupWithViewPager之前的选项卡，这就是您的代码无法工作的原因。因此，首先设置选项卡，然后设置侦听器代码。
尝试如下：
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;
}
});

对于ViewPager2 (最低版本1.1.0)，您可以在TabLayoutMediator中完成这一任务。
new TabLayoutMediator(tabLayout, pager,
(tab, position) -> {
tab.view.setClickable(false);
}
).attach();在build.gradle中

可触摸数组列表将解决此问题。
宣布活动
var touchableList: ArrayList<View>? = ArrayList()禁用所有选项卡
touchableList = tabLayout?.touchables
touchableList?.forEach { it.isEnabled = false }启用选项卡
touchableList?.get(0)?.isEnabled = true页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
