(一)listView内容不正常显示(注:网上有很多方法)
重写ListView的onMeasure方法
/** * 以下要重写,防止listview在scrollview容器中不能正常显示的问题 * @param widthMeasureSpec * @param heightMeasureSpec */ @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, expandSpec); }
(二)ScrollView的上下事件与ListView的左右事件冲突
重写ListView
public class MySwipeMenuListView extends SwipeMenuListView { public MySwipeMenuListView(Context context) { super(context); mGestureDetector = new GestureDetector(context,onGestureListener); } public MySwipeMenuListView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); mGestureDetector = new GestureDetector(context,onGestureListener); } public MySwipeMenuListView(Context context, AttributeSet attrs) { super(context, attrs); mGestureDetector = new GestureDetector(context,onGestureListener); }// @Override// public boolean onInterceptTouchEvent(MotionEvent ev) {// switch (ev.getAction()) {// case MotionEvent.ACTION_DOWN://// //setParentScrollAble(false);//当手指触到listview的时候,让父ScrollView交出ontouch权限,也就是让父scrollview 停住不能滚动// Log.w("MyLog", "onInterceptTouchEvent down");// case MotionEvent.ACTION_MOVE://// Log.w("MyLog", "onInterceptTouchEvent move");// break;//// case MotionEvent.ACTION_UP:// Log.w("MyLog", "onInterceptTouchEvent up");//// case MotionEvent.ACTION_CANCEL://// Log.w("MyLog", "onInterceptTouchEvent cancel");// //setParentScrollAble(true);//当手指松开时,让父ScrollView重新拿到onTouch权限//// break;// default:// break;//// }//// return super.onInterceptTouchEvent(ev) ;// } @Override public boolean onTouchEvent(MotionEvent ev) { boolean b = mGestureDetector.onTouchEvent(ev); Log.w("MyLog","-- "+ b+" --"); return super.onTouchEvent(ev); } private GestureDetector mGestureDetector; View.OnTouchListener mGestureListener; private GestureDetector.OnGestureListener onGestureListener = new GestureDetector.SimpleOnGestureListener(){// @Override// public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {// Log.w("MyLog","onFling");// float x = e2.getX() - e1.getX();// float y = e2.getY() - e1.getY();// if (Math.abs(y) >= Math.abs(x)){// setParentScrollAble(false);// return true;// }// //当手指触到listview的时候,让父ScrollView交出ontouch权限,也就是让父scrollview 停住不能滚动// setParentScrollAble(true);// return false;// } @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { Log.w("MyLog", "onScroll"); if (distanceY != 0 && distanceX != 0) { } if (Math.abs(distanceY) >= Math.abs(distanceX)) { return true; } //当手指触到listview的时候,让父ScrollView交出ontouch权限,也就是让父scrollview 停住不能滚动 setParentScrollAble(false); return false; } }; /** * 是否把滚动事件交给父scrollview * * @param flag */ private void setParentScrollAble(boolean flag) { //这里的parentScrollView就是listview外面的那个scrollview Log.w("MyLog", "setParentScrollAble -- " + flag); getParent().requestDisallowInterceptTouchEvent(!flag); }}
