导航抽屉在Android滞后 [英] Navigation Drawer lag on Android

问题描述

我在使用导航抽屉有问题，实在是太慢了，我正在寻找解决的办法是先关上抽屉，然后展示活动，但它不工作，当然我想的东西。

 私有类DrawerItemClickListener实现ListView.OnItemClickListener {
        @覆盖
        公共无效onItemClick（适配器视图＆LT;＆GT;母公司视图中查看，INT posicao，长ID）{
            setLastPosition（posicao）;
            setFragmentList（lastPosition）;
            layoutDrawer.closeDrawer（linearDrawer）;
        }
    }

    私人OnClickListener userOnClick =新OnClickListener（）{
        @覆盖
        公共无效的onClick（视图v）{
            layoutDrawer.closeDrawer（linearDrawer）;
        }
    };

    私人无效setFragmentList（INT posicao）{

        FragmentManager fragmentManager = getSupportFragmentManager（）;
        片段片段=新FragmentViagens（）;

        开关（posicao）{

            情况下0：
                fragmentManager.beginTransaction（）代替（R.id.content_frame，片段）.commit（）。
                打破;
            情况1：
                。fragmentManager.beginTransaction（）代替（R.id.content_frame，新FragmentPedidos（））提交（）;
                打破;
            案例2：
                。fragmentManager.beginTransaction（）代替（R.id.content_frame，新FragmentClientes（））提交（）;
                打破;

        }

        navigationAdapter.setChecked（posicao，真正的）;
        setTitleFragments（lastPosition）;
        navigationAdapter.resetarCheck（）;
        layoutDrawer.closeDrawer（linearDrawer）;

    }
 

解决方案

您可以做这样既避免抽屉滞后，改变您的 onItemClick

  layoutDrawer.closeDrawer（linearDrawer）;
setLastPosition（posicao）;
新的处理程序（）。postDelayed（新的Runnable（）{
        @覆盖
        公共无效的run（）{
            setFragmentList（lastPosition）;
        }
    }，200）;
 

I'm having a problem with Navigation Drawer , it is too slow, the solution I'm looking for is to close the drawer first and then show the activity, but It is not working, certainly I'm missing something.

private class DrawerItemClickListener implements ListView.OnItemClickListener {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int posicao, long id) {
            setLastPosition(posicao);
            setFragmentList(lastPosition);
            layoutDrawer.closeDrawer(linearDrawer);
        }
    }

    private OnClickListener userOnClick = new OnClickListener() {
        @Override
        public void onClick(View v) {
            layoutDrawer.closeDrawer(linearDrawer);
        }
    };

    private void setFragmentList(int posicao) {

        FragmentManager fragmentManager = getSupportFragmentManager();
        Fragment fragment = new FragmentViagens();

        switch (posicao) {

            case 0:
                fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
                break;
            case 1:
                fragmentManager.beginTransaction().replace(R.id.content_frame, new FragmentPedidos()).commit();
                break;
            case 2:
                fragmentManager.beginTransaction().replace(R.id.content_frame, new FragmentClientes()).commit();
                break;

        }

        navigationAdapter.setChecked(posicao, true);
        setTitleFragments(lastPosition);
        navigationAdapter.resetarCheck();
        layoutDrawer.closeDrawer(linearDrawer);

    }

解决方案

You can do It this way to avoid drawer lag, change your onItemClick:

layoutDrawer.closeDrawer(linearDrawer);
setLastPosition(posicao);
new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            setFragmentList(lastPosition);
        }
    }, 200);
