在选项卡式活动中禁用滑动（Android Studio）

Question

我想要禁用选项卡式活动中的滑动功能。我尝试了一些我发现的例子，但它没有奏效，或者代码完全不同。 这里是我的代码：

MainActivity.java：

package com.example; 

import android.support.design.widget.TabLayout; 
import android.support.design.widget.FloatingActionButton; 
import android.support.design.widget.Snackbar; 
import android.support.v4.app.NotificationCompat; 
import android.support.v7.app.ActionBar; 
import android.support.v7.app.AppCompatActivity; 
import android.support.v7.widget.Toolbar; 

import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentPagerAdapter; 
import android.support.v4.view.ViewPager; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.view.ViewGroup; 

import android.widget.TextView; 

public class MainActivity extends AppCompatActivity { 


    private SectionsPagerAdapter mSectionsPagerAdapter; 


    private ViewPager mViewPager; 

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

     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
     // Create the adapter that will return a fragment for each of the three 
     // primary sections of the activity. 
     mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager()); 

     // Set up the ViewPager with the sections adapter. 
     mViewPager = (ViewPager) findViewById(R.id.container); 
     mViewPager.setAdapter(mSectionsPagerAdapter); 

     TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs); 
     tabLayout.setupWithViewPager(mViewPager); 

     FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
     fab.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG) 
         .setAction("Action", null).show(); 
      } 
     }); 

    } 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 

     //noinspection SimplifiableIfStatement 
     if (id == R.id.action_settings) { 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 




    public class SectionsPagerAdapter extends FragmentPagerAdapter { 

     public SectionsPagerAdapter(FragmentManager fm) { 
      super(fm); 
     } 

     @Override 
     public Fragment getItem(int position) { 
      // getItem is called to instantiate the fragment for the given page. 
      // Return a PlaceholderFragment (defined as a static inner class below). 

      switch (position) { 
       case 0: 
        return FragmentOne.newInstance("a","b"); 
       case 1: 
        return FragmentTwo.newInstance("a","b"); 
       case 2: 
        return FragmentThree.newInstance("a","b"); 
       case 3: 
        return FragmentFour.newInstance("a","b"); 
       case 4: 
        return FragmentFive.newInstance("a","b"); 
       default: 
        return FragmentThree.newInstance("a","b"); 
      } 

     } 

     @Override 
     public int getCount() { 
      return 5; 
     } 

     @Override 
     public CharSequence getPageTitle(int position) { 
      switch (position) { 
       case 0: 
        return "One"; 
       case 1: 
        return "Two"; 
       case 2: 
        return "Three"; 
       case 3: 
        return "Four"; 
       case 4: 
        return "Five"; 
      } 
      return null; 
     } 
    } 


    public static class PlaceholderFragment extends Fragment { 

     private static final String ARG_SECTION_NUMBER = "section_number"; 


     public static PlaceholderFragment newInstance(int sectionNumber) { 
      PlaceholderFragment fragment = new PlaceholderFragment(); 
      Bundle args = new Bundle(); 
      args.putInt(ARG_SECTION_NUMBER, sectionNumber); 
      fragment.setArguments(args); 
      return fragment; 
     } 

     public PlaceholderFragment() { 
     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
           Bundle savedInstanceState) { 
      View rootView = inflater.inflate(R.layout.fragment_main, container, false); 
      TextView textView = (TextView) rootView.findViewById(R.id.section_label); 
      textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER))); 
      return rootView; 
     } 
    } 
} 

activity_main.xml中

您需要创建自定义ViewPager类这种方式。

public class CustomViewPager extends ViewPager { 
private boolean swipeable = false; 

public CustomViewPager(Context context) { 
    super(context); 
} 

public CustomViewPager(Context context, AttributeSet attrs) { 
    super(context, attrs); 
} 

// Call this method in your motion events when you want to disable or enable 
// It should work as desired. 
public void setSwipeable(boolean swipeable) { 
    this.swipeable = swipeable; 
} 

@Override 
public boolean onInterceptTouchEvent(MotionEvent arg0) { 
    return (this.swipeable) ? super.onInterceptTouchEvent(arg0) : false; 
} 

现在

CustomViewPager ViewPagerObj = (CustomViewPager)findViewById(R.id.container); 
    ViewPagerObj.setSwipeable(false); 

你应该在你的XML添加此

<Your_packagename.CustomViewPager 
    android:id="@+id/container" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />
