我试图使用导航抽屉切换活动，而不是碎片

Question

以下是我的申请代码。香港专业教育学院曾尝试过这方面的工作，但没有遇到任何对我来说成功的事情。没有改变碎片我可以做什么。

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

        if (id == R.id.my_account) {

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

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

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

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

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

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

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

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

        } else if (id == nav_fanzone) {

        }

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

将 onNavigationItemSelected（）更改为：

public boolean onNavigationItemSelected(MenuItem item) {
        // Handle navigation view item clicks here.
        switch(item.getItemId()){
             case R.id.my_account:
               //Do code here
              break;
             case R.id.nav_news:
               //Do code here
             break;
             case R.id.nav_live:
              //Do code here
             break;
             case R.id.nav_media:
              //Do code here
             break;
             case R.id.nav_calendar:
              //Do code here
             break;
             case R.id.nav_results:
              //Do code here
             break;
             case R.id.nav_about:
              //Do code here
             break;
             case R.id.nav_shop:
              //Do code here
             break;
             case R.id.nav_social_media:
              //Do code here
             break;
             case R.id.nav_fanzone:
              //Do code here
             break;

}

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

对于更改活动，只需在所有切换案例中添加：

Intent intent=new Intent(your_activity.this,your_next_activity.class);
startActivity(intent);
