當我向左掃滑動標籤左側導航抽屜打開了

Question

我使用的材料設計滑動片（smartTabLayout），在這裏：https://github.com/ogaclejapan/SmartTabLayout

而且，材料設計方導航抽屜（Android的駐留菜單），在這裏：https://github.com/SpecialCyCi/AndroidResideMenu

我面臨的問題是：當我從刷卡任何標籤的左側，導航抽屜打開，但它是好的，當我向右滑動。

下面是代碼：

MainActivity.java：

public class MainActivity extends AppCompatActivity implements View.OnClickListener { 

    private static final String TAG = "MainActivity"; 

    private SectionsPageAdapter sectionsPageAdapter; 
    private ViewPager viewPager; 
    Toolbar toolbar; 
    ResideMenu resideMenu; 
    SmartTabLayout smartTabLayout; 
    private MainActivity mContext; 
    private ResideMenuItem equalizer; 
    private ResideMenuItem ringtonemaker; 
    private ResideMenuItem identifysong; 
    private ResideMenuItem themes; 
    private ResideMenuItem rateus; 


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

     mContext = MainActivity.this; 
     setUpMenu(); 


     toolbar = (Toolbar)findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 


     sectionsPageAdapter = new SectionsPageAdapter(getSupportFragmentManager()); 

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

     smartTabLayout = (SmartTabLayout) findViewById(R.id.viewpagertab); 
     smartTabLayout.setViewPager(viewPager); 



    } 


    private void setupViewPager(ViewPager viewPager) { 

     SectionsPageAdapter adapter = new SectionsPageAdapter(getSupportFragmentManager()); 
     adapter.addFragment(new Albums(), "Albums"); 
     adapter.addFragment(new Artists(), "Artists"); 
     adapter.addFragment(new Songs(), "Songs"); 
     adapter.addFragment(new Playlists(), "Playlists"); 
     adapter.addFragment(new Genres(), "Genres"); 
     adapter.addFragment(new My_Files(), "My Files"); 
     viewPager.setAdapter(adapter); 
     viewPager.setPageTransformer(true, new CubeInTransformer()); 

    } 

     private void setUpMenu() { 

     // attach to current activity; 
     resideMenu = new ResideMenu(this); 
     resideMenu.setBackground(R.drawable.city); 
     resideMenu.attachToActivity(this); 
     //valid scale factor is between 0.0f and 1.0f. leftmenu'width is 150dip. 
     resideMenu.setScaleValue(0.6f); 

     // create menu items; 
     equalizer = new ResideMenuItem(this, R.drawable.city, "Equalizer"); 
     ringtonemaker = new ResideMenuItem(this, R.drawable.city, "Ringtone Maker"); 
     identifysong = new ResideMenuItem(this, R.drawable.city, "Identify Song"); 
     themes = new ResideMenuItem(this, R.drawable.city, "Theme"); 
     rateus = new ResideMenuItem(this, R.drawable.city, "Rate us"); 

     equalizer.setOnClickListener(this); 
     ringtonemaker.setOnClickListener(this); 
     identifysong.setOnClickListener(this); 
     themes.setOnClickListener(this); 
     rateus.setOnClickListener(this); 

     resideMenu.addMenuItem(equalizer, ResideMenu.DIRECTION_LEFT); 
     resideMenu.addMenuItem(ringtonemaker, ResideMenu.DIRECTION_LEFT); 
     resideMenu.addMenuItem(identifysong, ResideMenu.DIRECTION_LEFT); 
     resideMenu.addMenuItem(themes, ResideMenu.DIRECTION_LEFT); 
     resideMenu.addMenuItem(rateus, ResideMenu.DIRECTION_LEFT); 

     // You can disable a direction by setting -> 
     resideMenu.setSwipeDirectionDisable(ResideMenu.DIRECTION_RIGHT); 

    } 



    @Override 
    public void onClick(View view) { 

    } 
} 

適配器滑動選項卡：

class SectionsPageAdapter extends FragmentPagerAdapter { 

    private final List<Fragment> FragmentList = new ArrayList<>(); 
    private final List<String> FragmentTitleList = new ArrayList<>(); 

    public void addFragment(Fragment fragment, String Title){ 

     FragmentList.add(fragment); 
     FragmentTitleList.add(Title); 
    } 


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

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

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

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

activity_main.xml中：

Answer 1

我可以看到here方法dispatchTouchEvent沒有可能設置的阻力區，以避免ViewPager觸摸攔截。所以，你可以分叉這個回購並添加該功能。或者你可以重寫活動的dispatchTouchEvent：

boolean menuDragging = false; 

public boolean isInsideMenuDragArea(MotionEvent ev) { 
    return ev.getX() < 200; // THIS IS PIXELS, NOT DP! 
} 

@Override 
public boolean dispatchTouchEvent(MotionEvent ev) { 
    if (menuDragged) return resideMenu.dispatchTouchEvent(ev); 
    if (ev.getAction() == MotionEvent.ACTION_DOWN) { 
     if (!isInsideMenuDragArea(ev)) { 
       return super.dispatchTouchEvent(ev); 
     } else { 
       menuDragging = true; 
     }  
    } else if (ev.getAction() == MotionEvent.ACTION_UP) { 
     menuDragging = false; 
    } 
    return resideMenu.dispatchTouchEvent(ev); 

} 

我認爲這是足以明白我的意思

編輯：

如果你想，當你刷卡離開，打開側導航抽屜第一個選項卡

viewPager.setOnPageChangeListener(new OnPageChangeListener() { 
    public void onPageScrollStateChanged(int state) {} 
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {} 

    public void onPageSelected(int position) { 
     if (position == 0) resideMenu.removeIgnoredView(viewPager); 
     else resideMenu.addIgnoredView(viewPager); 
    } 
}); 

EDIT2： 添加到您的活動

boolean resideMenuEnabled = true; 

public void setResideMenuEnabled(boolean enabled) { 
    if (resideMenuEnabled != enabled) { 
      if (enabled) resideMenu.removeIgnoredView(viewPager); 
      else resideMenu.addIgnoredView(viewPager); 
      resideMenuEnabled = enabled; 
    } 
} 

而且使用這樣的

viewPager.setOnPageChangeListener(new OnPageChangeListener() { 
    public void onPageScrollStateChanged(int state) {} 
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {} 

    public void onPageSelected(int position) { 
     if (position == 0) setResideMenuEnabled(true); 
     else setResideMenuEnabled(false); 
    } 
});
