如何调用Android活动点击滑块菜单项

Question

我想调用简单的Android活动上点击滑块菜单项，在片段的地方。我试图调用活动使用片段，但它显示什么

请帮帮我。

谁能提出替代方法?

private void displayView(int position) {
    // update the main content by replacing fragments
    Fragment fragment = null;
    switch (position) {
    case 0:
        Log.e("", "In Fragment "+position);
        fragment = new About_us_Activity();
        //startActivity(new Intent(this,Home_Activity.class));
        break;
    case 1:
        //fragment = new About_us_frag();
        Log.e("", "In Fragment "+position);
        break;
    case 2:
        Log.e("", "In Fragment "+position);
        fragment = new About_us_frag1();
        break;
    default:
        break;
    }
    if (fragment != null) {

        Log.e("", "In Fragment");
        FragmentManager fragmentManager = getFragmentManager();
        fragmentManager.beginTransaction()
                .replace(R.id.frame_container, fragment).commit();
        // update selected item and title, then close the drawer
    } else {
        // error in creating fragment
        Log.e("MainActivity", "Error in creating fragment");
    }
}

首先将onItemClickListener应用到抽屉列表。

mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            mDrawerLayout.closeDrawers();
            displayView(position);
        }
    });

在你的DisplayView方法中:

private void displayView(int position) {
    switch (position) {
        case 1:
                Intent intent = new Intent(getApplicationContext(), MyActivity1.class);
                startActivity(intent);                   
                break;
        case 2:
                Intent intent1 = new Intent(getApplicationContext(),MyActivity2.class);
                startActivity(intent1);                   
                break;

        default:break;
    }
}

MyActivity1和MyActivity2是活动。你可以试试这个方法，它对我很有效。
