GraleleファイルでAPIバージョンを変更すると、このエラーが発生します。最終GestureDetectorCompatから継承できません。 私はapi 22を使用する場合は正常に動作しますが、私はapi 23を使用するとこのエラーが発生します。なぜですか？ここでAndroid - 最終的なGestureDetectorCompatから継承することはできません
私のコードは次のとおりです。 ファイル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;
}
}
}
}
とGradleのファイル：このコード、それを仕事に
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')
}
が、私は、API 23とのGradleに変更した場合、私はしましたエラーが発生しました
...
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'
...
誰でも手伝ってもらえますか？おかげ
