单击导航抽屉菜单中的项目后打开新活动

Question

大家好，我是初学者，刚开始在 android 中编码，我找到了一个关于如何制作导航抽屉的教程。

教程链接：- http://www.android4devs.com/2015/06/navigation-view-material-design-support.html

我想知道如果我点击导航抽屉中的选项，有什么方法可以打开一个新活动，这对回答有很大帮助。

先感谢您

Answer 1

mDrawerList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {
switch (position) {
   case 1:
         Intent intent= new Intent(CurrentActivity.this,AnotherActivity.class);
         startActivity(intent);
         break;
    case 2:
          ...
    default:
         break;
    }
  }
});

我正在使用

public boolean onNavigationItemSelected(MenuItem item) {
        // Handle navigation view item clicks here.
        int id = item.getItemId();

        if (id == R.id.nav_cinema) {
                Intent cinemaIntent = new Intent(this, CinemaActivity.class);
                startActivity(cinemaIntent);
        } else if (id == R.id.nav_tv) {

        } else if (id == R.id.nav_tvseason) {

        } else if (id == R.id.nav_share) {

        } else if (id == R.id.nav_send) {

        }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

它对我有用:)（这是默认的Android导航抽屉菜单）

Answer 3

 public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int id = item.getItemId();

    if (id == R.id.activity_about) {
        Intent activity_about = new Intent(this, AboutActivity.class);
        startActivity(activity_about);
    } else if (id == R.id.nav_gallery) {

    } else if (id == R.id.nav_slideshow) {

    } else if (id == R.id.nav_manage) {

    } else if (id == R.id.nav_share) {

    } else if (id == R.id.nav_send) {

    }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

}

作为新的实现，您可以使用引入了NavigationView类和DrawerLayout模式的全新设计支持库。 查看发行说明以获取更多信息。
