软键盘遮挡Edittext

1.当无listview页面中有Edittext，使用根布局被scrollview包裹即可
2.当Edittext嵌套在ListView RecyclerView时，软键盘闪退，用scrollview包裹list即可。

   <com.face2facelibrary.common.view.MyScrollview
        android:layout_width="match_parent"
        android:layout_above="@id/qa_result_stop_tv"
        android:layout_below="@+id/notice_tv"
        android:layout_height="match_parent">

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

            android:descendantFocusability="beforeDescendants"
            android:fastScrollEnabled="false" />
    </com.face2facelibrary.common.view.MyScrollview>

scrollview与listview，recycleview冲突或者展示不全冲突
public class MyScrollview extends ScrollView {
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);
}

}
