タッチイベントでイメージスライダの自動スクロールを停止する方法

Question

カスタムを使用して自動イメージスライダを作成しましたViewPagerタッチ時にイメージの自動スライディングを停止し、タッチ時にスライダを再開する方法を知りたい解放されます。ここで

は私CustomViewPager.javaです： - ここに

public class CustomViewPager extends ViewPager { 

    private boolean isPagingEnabled = true; 

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

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

    @Override 
    public boolean onTouchEvent(MotionEvent event) { 

     return this.isPagingEnabled && super.onTouchEvent(event); 
    } 

    @Override 
    public boolean onInterceptTouchEvent(MotionEvent event) { 
     return this.isPagingEnabled && super.onInterceptTouchEvent(event); 
    } 

    public void setPagingEnabled(boolean b) { 
     this.isPagingEnabled = b; 
    } 


} 

はImageAdapter.javaです： - ここに

public class SlidingImage_Adapter extends PagerAdapter { 


    Context context; 
    int images[]; 
    LayoutInflater inflater; 


    public SlidingImage_Adapter(Context context, int images[]) { 

     this.context = context; 
     this.images = images; 
     inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 



    @Override 
    public void destroyItem(ViewGroup container, int position, Object object) { 
     container.removeView((View) object); 
    } 

    @Override 
    public int getCount() { 
     return images.length; 
    } 

    @Override 
    public Object instantiateItem(ViewGroup container, final int position) { 
     View itemView = inflater.inflate(R.layout.sliding_images, container, false); 


     final ImageView imageView = (ImageView) itemView 
       .findViewById(R.id.image); 


     imageView.setImageResource(images[position]); 

     container.addView(itemView, 0); 

     return itemView; 
    } 

    @Override 
    public boolean isViewFromObject(View view, Object object) { 
     return view.equals(object); 
    } 

    @Override 
    public void restoreState(Parcelable state, ClassLoader loader) { 
    } 

    @Override 
    public Parcelable saveState() { 
     return null; 
    } 

} 

は、私はこのCustomViewPagerを使用していますFragment.javaは次のとおりです。 -

public class HomeFragment extends Fragment { 

    private static final String ARG_PARAM1 = "param1"; 
    private static final String ARG_PARAM2 = "param2"; 
    TextView tv_slider, tv_button; 
    RelativeLayout dummyView; 
    CustomViewPager mViewPager; 

    Timer timer; 
    final long DELAY_MS = 1000;//delay in milliseconds before task is to be executed 
    final long PERIOD_MS = 3000; 



    private static int currentPage = 0; 
    private static int NUM_PAGES = 0; 
    int images[] = {R.drawable.ecommerce, R.drawable.digital_marketing, R.drawable.explainer, R.drawable.it_services, 
      R.drawable.mobile_app, R.drawable.seo, R.drawable.software, R.drawable.webdesign}; 
    SlidingImage_Adapter imageAdapter; 


    // TODO: Rename and change types of parameters 
    private String mParam1; 
    private String mParam2; 

    private OnFragmentInteractionListener mListener; 

    public HomeFragment() { 

    } 

    public static HomeFragment newInstance(String param1, String param2) { 
     HomeFragment fragment = new HomeFragment(); 
     Bundle args = new Bundle(); 
     args.putString(ARG_PARAM1, param1); 
     args.putString(ARG_PARAM2, param2); 
     fragment.setArguments(args); 
     return fragment; 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     if (getArguments() != null) { 
      mParam1 = getArguments().getString(ARG_PARAM1); 
      mParam2 = getArguments().getString(ARG_PARAM2); 


     } 
    } 


    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View v = inflater.inflate(R.layout.fragment_home, container, false); 

     tv_slider=(TextView)v.findViewById(R.id.tv_slider); 
     tv_slider.setTypeface(EasyFonts.robotoLight(this.getActivity())); 
     tv_button=(TextView)v.findViewById(R.id.tv_button); 
     tv_button.setTypeface(EasyFonts.robotoLight(this.getActivity())); 


     mViewPager = (CustomViewPager) v.findViewById(R.id.pager); 
     imageAdapter = new SlidingImage_Adapter(getActivity(),images); 
     mViewPager.setAdapter(imageAdapter); 




     final Handler handler = new Handler(); 
     final Runnable Update = new Runnable() { 
      public void run() { 
       if (currentPage == NUM_PAGES) { 
        currentPage = 0; 
       } 
       mViewPager.setCurrentItem(currentPage++, true); 

      } 
     }; 

       Timer swipeTimer = new Timer(); 
     swipeTimer.schedule(new TimerTask() { 
      @Override 
      public void run() { 
       handler.post(Update); 
      } 
     }, DELAY_MS, PERIOD_MS); 






     CirclePageIndicator indicator = (CirclePageIndicator) 
       v.findViewById(R.id.indicator); 

     indicator.setViewPager(mViewPager); 

     final float density = getResources().getDisplayMetrics().density; 

     //Set circle indicator radius 
     indicator.setRadius(3 * density); 

     NUM_PAGES =images.length; 



     // Pager listener over indicator 
     indicator.setOnPageChangeListener(new CustomViewPager.OnPageChangeListener() { 

      @Override 
      public void onPageSelected(int position) { 
       currentPage = position; 

      } 



      @Override 
      public void onPageScrolled(int pos, float arg1, int arg2) { 

       switch (pos){ 

        case 0: 
         tv_slider.setText(getString(R.string.es_content)); 
         break; 

        case 1: 
         tv_slider.setText(getString(R.string.dm_content)); 
         break; 

        case 2:

         break; 

        case 3:

      }

     return v; 


    } 

Answer 1

を働いている私のコード例です。

Answer 2

thisのドキュメントによると、あなたが既にオーバーラップしているonTouchEvent隠された場所はどこを見るかです。

あなたのメソッドで行ったのと同じように、今度はsuper.onTouchEvent（event）を呼び出す代わりに。独自のカスタムアクションを実装します。 superを呼び出すと、デフォルトの動作を受け入れます。

これは私がサードパーティのライブラリ"Library Link"を発見したし、それが組み込まれている自動スクロールを開始および停止する方法の良い=>

public class MainActivity extends AppCompatActivity { 

    final long DELAY_MS = 1000;//delay in milliseconds before task is to be executed 
    final long PERIOD_MS = 3000; 
    int currentPage = 0; 
    public Timer timer; 
    public Timer swipeTimer; 
    public static boolean startSlider = true; 
    public TextView textView; 
    public LinearLayout layout; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     textView = (TextView) findViewById(R.id.textView); 
     layout = (LinearLayout) findViewById(R.id.layout); 

     final Handler handler = new Handler(); 
     final Runnable Update = new Runnable() { 
      public void run() { 

       if (currentPage == 6) { 
        currentPage = 0; 
       } 
       currentPage++; 
       textView.setText(String.valueOf(currentPage)); 

      } 
     }; 


     swipeTimer = new Timer(); 
     swipeTimer.schedule(new TimerTask() { 
      @Override 
      public void run() { 
       if (startSlider){ 
        handler.post(Update); 
       } 

      } 
     }, DELAY_MS, PERIOD_MS); 

     layout.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       if (startSlider){ 
        startSlider = false; 
       }else { 
        startSlider = true; 
       } 
      } 
     }); 

    } 

}
