使用Android在一个框架布局中显示所有活动，碎片

Question

我正在DrawerLayout使用Slider Menu，它是主要的活动。它包含Frame Layout。

主页面为主页，将在Frame Layout中打开，且为Fragment。它工作正常。现在，Home包含2个按钮，我根据点击Activity打开不同的Button。

它会打开新的Activity，但我想在Home所在的相同Frame Layout中打开它，这样我就可以在所有Activity中扩展Slider菜单。

如何实施？

home.xml：

        llPractice = rootView.findViewById(R.id.llPractice);

                Intent openRandomQuestion = new Intent(getActivity(),
                        Practice.class);
                startActivity(openRandomQuestion);
            }

        llStudy.setOnClickListener(new View.OnClickListener() {

                        .replace(R.id.frame_container, new Study()).commit();

        llTest.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                Intent openRandomQuestion = new Intent(getActivity(),
                    Test.class);
                startActivity(openRandomQuestion);
            }
        });


        return rootView;
    }
}

解决方案是：

创建BaseActivity，然后在所有活动中扩展此BaseActivity：

示例代码：

        public class BaseActivity extends Activity {

            // Access you navaigation drawer here


            private DrawerLayout mDrawerLayout;
            private ListView mDrawerList;


         }

    public class YourActivity extends BaseActivity {


    }

一旦有look here和here too来创建DrawerLayout的工作演示。
