Android - не может наследовать от окончательного GestureDetectorCompat

Question

Я получаю эту ошибку «не может наследовать от окончательного GestureDetectorCompat» при изменении версии API в файле gradle. Если я использую api 22, он отлично работает, но если я использую api 23, у меня есть эта ошибка, почему?

Вот мой код: файл ClickItemTouchListener.java

package com.ddfilms.dado.RecyclerView.Utils; 

import android.content.Context; 
import android.os.Build; 
import android.support.v4.view.GestureDetectorCompat; 
import android.support.v4.view.MotionEventCompat; 
import android.support.v7.widget.RecyclerView; 
import android.support.v7.widget.RecyclerView.OnItemTouchListener; 
import android.view.GestureDetector.SimpleOnGestureListener; 
import android.view.MotionEvent; 
import android.view.View; 

abstract class ClickItemTouchListener implements OnItemTouchListener { 
    private static final String LOGTAG = "ClickItemTouchListener"; 

    private final GestureDetectorCompat mGestureDetector; 

    ClickItemTouchListener(RecyclerView hostView) { 
     mGestureDetector = new ItemClickGestureDetector(hostView.getContext(), 
       new ItemClickGestureListener(hostView)); 
    } 

    private boolean isAttachedToWindow(RecyclerView hostView) { 
     if (Build.VERSION.SDK_INT >= 19) { 
      return hostView.isAttachedToWindow(); 
     } else { 
      return (hostView.getHandler() != null); 
     } 
    } 

    private boolean hasAdapter(RecyclerView hostView) { 
     return (hostView.getAdapter() != null); 
    } 

    @Override 
    public boolean onInterceptTouchEvent(RecyclerView recyclerView, MotionEvent event) { 
     if (!isAttachedToWindow(recyclerView) || !hasAdapter(recyclerView)) { 
      return false; 
     } 

     mGestureDetector.onTouchEvent(event); 
     return false; 
    } 

    @Override 
    public void onTouchEvent(RecyclerView recyclerView, MotionEvent event) { 
     // We can silently track tap and and long presses by silently 
     // intercepting touch events in the host RecyclerView. 
    } 

    abstract boolean performItemClick(RecyclerView parent, View view, int position, long id); 

    abstract boolean performItemLongClick(RecyclerView parent, View view, int position, long id); 

    private class ItemClickGestureDetector extends GestureDetectorCompat { 
     private final ItemClickGestureListener mGestureListener; 

     public ItemClickGestureDetector(Context context, ItemClickGestureListener listener) { 
      super(context, listener); 
      mGestureListener = listener; 
     } 

     @Override 
     public boolean onTouchEvent(MotionEvent event) { 
      final boolean handled = super.onTouchEvent(event); 

      final int action = event.getAction() & MotionEventCompat.ACTION_MASK; 
      if (action == MotionEvent.ACTION_UP) { 
       mGestureListener.dispatchSingleTapUpIfNeeded(event); 
      } 

      return handled; 
     } 
    } 

    private class ItemClickGestureListener extends SimpleOnGestureListener { 
     private final RecyclerView mHostView; 
     private View mTargetChild; 

     public ItemClickGestureListener(RecyclerView hostView) { 
      mHostView = hostView; 
     } 

     public void dispatchSingleTapUpIfNeeded(MotionEvent event) { 
      // When the long press hook is called but the long press listener 
      // returns false, the target child will be left around to be 
      // handled later. In this case, we should still treat the gesture 
      // as potential item click. 
      if (mTargetChild != null) { 
       onSingleTapUp(event); 
      } 
     } 

     @Override 
     public boolean onDown(MotionEvent event) { 
      final int x = (int) event.getX(); 
      final int y = (int) event.getY(); 

      mTargetChild = mHostView.findChildViewUnder(x, y); 
      return (mTargetChild != null); 
     } 

     @Override 
     public void onShowPress(MotionEvent event) { 
      if (mTargetChild != null) { 
       mTargetChild.setPressed(true); 
      } 
     } 

     @Override 
     public boolean onSingleTapUp(MotionEvent event) { 
      boolean handled = false; 

      if (mTargetChild != null) { 
       mTargetChild.setPressed(false); 

       final int position = mHostView.getChildPosition(mTargetChild); 
       final long id = mHostView.getAdapter().getItemId(position); 
       handled = performItemClick(mHostView, mTargetChild, position, id); 

       mTargetChild = null; 
      } 

      return handled; 
     } 

     @Override 
     public boolean onScroll(MotionEvent event, MotionEvent event2, float v, float v2) { 
      if (mTargetChild != null) { 
       mTargetChild.setPressed(false); 
       mTargetChild = null; 

       return true; 
      } 

      return false; 
     } 

     @Override 
     public void onLongPress(MotionEvent event) { 
      if (mTargetChild == null) { 
       return; 
      } 

      final int position = mHostView.getChildPosition(mTargetChild); 
      final long id = mHostView.getAdapter().getItemId(position); 
      final boolean handled = performItemLongClick(mHostView, mTargetChild, position, id); 

      if (handled) { 
       mTargetChild.setPressed(false); 
       mTargetChild = null; 
      } 
     } 
    } 
} 

и Gradle файл:

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 22 
    buildToolsVersion "22.0.1" 

    defaultConfig { 
     applicationId "com.ddfilms.dado" 
     minSdkVersion 16 
     targetSdkVersion 22 
     versionCode 4 
     versionName "2.0" 
     multiDexEnabled true 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
    dexOptions { 
     preDexLibraries = false 
    } 
} 

dependencies { 
    compile 'com.android.support:appcompat-v7:22.1.0' 
    compile 'com.android.support:cardview-v7:22.+' 
    compile 'com.squareup.picasso:picasso:2.5.+' 
    compile 'com.android.support:recyclerview-v7:22.1.0' 
    compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar:3.1.2' 
    compile 'com.readystatesoftware.systembartint:systembartint:1.0.3' 
    compile files('libs/ksoap2-android-assembly-3.2.0-jar-with-dependencies.jar') 
    compile files('libs/android-query-full.0.26.7.jar') 
} 

С помощью этого кода это работает, но если я изменить в Gradle с апи 23 Я получена ошибка

... 
    compileSdkVersion 23 
    buildToolsVersion "23.0.3" 
... 
     targetSdkVersion 23 
... 
    compile 'com.android.support:appcompat-v7:23.4.0' 
    compile 'com.android.support:cardview-v7:23.+' 
    compile 'com.squareup.picasso:picasso:2.5.+' 
    compile 'com.android.support:recyclerview-v7:23.4.0' 
... 

Может ли кто-нибудь мне помочь? Благодаря

Answer 1

переписывает GestureDetectorCompat.java, удалить финал, как это:

public class GestureDetectorCompat { 
    .... 
} 

Answer 2

Изменения compile 'com.android.support:recyclerview-v7:23.4.0' в вашем приложении gradle.build к

compile 'com.android.support:recyclerview-v7:23.1.1'
