解決ScrollView與ReclerView的滑動衝突問題

原創

先是工具類

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.ViewConfiguration;
import android.widget.ScrollView;

/**
 * Created by huihuui on 16/9/5.
 * 這是複寫的ScrollView,
 * 解決ScrollView與其內部組件滑動衝突的,可以直接定義XML文件的時候調用
 */
public class MyScrollview extends ScrollView{

    Context context;
    private int downX;
    private int downY;
    private int mTouchSlop;

    public MyScrollview(Context context) {
        super(context);
        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
    }

    public MyScrollview(Context context, AttributeSet attrs) {
        super(context, attrs);
        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
    }

    public MyScrollview(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent e) {
        int action = e.getAction();
        switch (action) {
            case MotionEvent.ACTION_DOWN:
                downX = (int) e.getRawX();
                downY = (int) e.getRawY();
                break;
            case MotionEvent.ACTION_MOVE:
                int moveY = (int) e.getRawY();
                if (Math.abs(moveY - downY) > mTouchSlop) {
                    return true;
                }
        }
        return super.onInterceptTouchEvent(e);
    }
}

接下來就是在XML文件中直接引用

<com.android.util.MyScrollview
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

                <ImageView
                    android:id="@+id/iv_mainn"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:scaleType="fitXY" />

                <TextView
                    android:id="@+id/tv_main"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_centerInParent="true"
                    android:gravity="center"
                    android:textColor="#FFFFFF"
                    android:textSize="35dp" />

            </RelativeLayout>

            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_below="@+id/iv_mainn">

                    <android.support.v7.widget.RecyclerView
                        android:id="@+id/rv_list"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content">
                    </android.support.v7.widget.RecyclerView>

            </RelativeLayout>
        </LinearLayout>
    </RelativeLayout>

</com.android.util.MyScrollview>
