1、判断是否是主线程

Looper.getMainLooper().getThread() == Thread.currentThread()

2、PopupWindow使用问题

在Android7.0上面如果使用如下方式会出现调用showAsDropDown方法PopupWindow顶到状态栏下方，而不是在指定View下方的现象,解决办法计算PopupWindow到屏幕底部实际需要的高度，不用MATCH_PARENT。

不合适

final PopupWindow window = new PopupWindow(view, FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT, true);

final PopupWindow window = new PopupWindow(view, FrameLayout.LayoutParams.MATCH_PARENT, getResources().getDisplayMetrics().heightPixels - xy - mTimeFilterView.getHeight(), true);

    private void showDateSelectDialog(View view, final FilterView floatFilterView) {
        int[] location = new int[2];
        mTimeFilterView.getLocationOnScreen(location);
        int y = location[1];
        int height = ScreenUtils.getScreenHeight(mActivity) - y - mTimeFilterView.getHeight();

        final PopupWindow window = new PopupWindow(view, FrameLayout.LayoutParams.MATCH_PARENT, height, true);
        // 设置PopupWindow的背景
        window.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#30000000")));
        // 设置PopupWindow是否能响应外部点击事件
        window.setOutsideTouchable(true);
        // 设置PopupWindow是否能响应点击事件
        window.setTouchable(true);
        window.getContentView().setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                window.dismiss();
            }
        });

        window.setOnDismissListener(new PopupWindow.OnDismissListener() {
            @Override
            public void onDismiss() {
                floatFilterView.setOpened(false);
            }
        });

        PopupWindowCompat.showAsDropDown(window, mTimeFilterView, Gravity.BOTTOM, 0, 0);
    }

3、BottomNavigationView设置图片、文字颜色不被改变

BottomNavigationView navigation = (BottomNavigationView) findViewById(R.id.navigation);
navigation.setItemIconTintList(null);
navigation.setItemTextColor(getResources().getColorStateList(R.drawable.app_item_text_color));//color selector

或者使用库：
