Android仿QQ消息长按横向提示框（二）
废话不多说直接上代码！！！！
一、为View、ListView/GridView绑定长按弹出横向气泡菜单，可在item上任意位置长按弹出

二、在代码中的使用，分别获取itemOnTouchListener和OnLongClickListener点击事件
private float mRawX, mRawY;//获取长按的位置
item.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
mRawX = event.getRawX();
mRawY = event.getRawY();
return false;
}
});
OnLongClickListener中的代码
List<String> popupMenuItemList = new ArrayList<>();
popupMenuItemList.add("复制");
popupMenuItemList.add("转发");
popupMenuItemList.add("收藏");
popupMenuItemList.add("删除");
PopupList popupList = new PopupList(mContext);
popupList.showPopupListWindow(view, position, mRawX, mRawY, popupMenuItemList, new PopupList.PopupListListener() {
@Override
public boolean showPopupList(View adapterView, View contextView, int contextPosition) {
return true;
}
@Override
public void onPopupListClick(View contextView, int contextPosition, int positions) {
Toast.makeText(mContext, contextPosition + "," + position, Toast.LENGTH_SHORT).show();
if (positions == 0) {//复制
ClipboardManager cm = (ClipboardManager) mContext.getSystemService(Context.CLIPBOARD_SERVICE);
cm.setText(sText);
} else if (positions == 1) {//转发
} else if (positions == 2) {//收藏
} else if (positions == 3) {//删除
}
}
});
大佬勿喷，请多多指教！
