抽屉式导航栏布局上的应用程序的所有活动 [英] Navigation Drawer Layout on all activities of the application

问题描述

我有两个活动 - MainActivity用户登录页面，第二个活动在ListView中显示用户的详细信息（用户制作项目）。我想创建一个抽屉式导航栏的布局，会出现在活动。 我在这里找到了解决办法。但问题是，我的第二个活动延伸ListActivity在ListView控件来显示用户的详细资料，所以我不能延长别的。这里是我的第二个活动：

 公共类ProjectList扩展ListActivity {
ArrayList的＆LT;串GT;时listItems =新的ArrayList＆LT;串GT;（）;
ArrayAdapter＆LT;串GT;适配器;
ListView控件的ListView;
JSONArray项目= NULL;@覆盖
保护无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.project_list_inflator）;
    ListView控件=（ListView控件）findViewById（android.R.id.list）;
    适配器=新ArrayAdapter＆LT;串GT;（这一点，android.R.layout.simple_list_item_1，listItems中）;
    listView.setAdapter（适配器）;
    新HttpGetHandler（）执行（）;
}私有类HttpGetHandler扩展的AsyncTask＆LT;弦乐，太虚，太虚＆GT; {
    字符串jsonUrl =某些URL;
    字符串imgUrl的=htt​​p://canvasflip.com/protected/app/elements/userElements/;
    @覆盖
    保护无效doInBackground（字符串... PARAMS）{
        HTTPGET HTTPGET =新HTTPGET（jsonUrl）;
        // HTTPGET httpGet1 =新HTTPGET（imgUrl的）;
        尝试{
            HTT presponse HTT presponse = MainActivity.httpClient.execute（HTTPGET）;
            HttpEntity httpEntity = HTT presponse.getEntity（）;
            InputStream的内容= httpEntity.getContent（）;
            字符串结果= convertToString（内容）;
            的JSONObject的JSONObject =新的JSONObject（结果）;
            项目= jsonObject.getJSONArray（项目）。
            ProjectList.this.runOnUiThread（新的Runnable（）{
                @覆盖
                公共无效的run（）{
                    尝试{
                        的for（int i = 0; I＆LT; projects.length（）;我++）{
                            的JSONObject p值= projects.getJSONObject（ⅰ）;
                            字符串title = p.getString（标题）;
                            listItems.add（职称）;
                            adapter.notifyDataSetChanged（）;
                        }                    }赶上（例外五）{
                        Log.d（MSG，e.toString（））;
                    }
                }
            }）;
        }赶上（例外五）{
            的System.out.println（e.getMessage（））;
        }
        返回null;
    }    公共字符串convertToString（的InputStream的InputStream）抛出IOException
        的BufferedReader的BufferedReader =新的BufferedReader（新的InputStreamReader（InputStream的））;
        串线=;
        字符串结果=;
        而（（行= bufferedReader.readLine（））！= NULL）{
            结果+ =行;        }
        inputStream.close（）;
        返回结果;
    }
 }
}
 

解决方案

只是使具有抽屉式导航implementaion源新活动

像公共类DrawerActivity扩展ListActivity
覆盖DrawerLayout为

  

保护DrawerLayout drawerLayout;

在你的抽屉活动的onCreate初始化抽屉布局，

  drawerLayout =（DrawerLayout）findViewById（R.id.drawer_layout1）;
 

和让你MainActivity扩展DrawerAcivity。

然后再更换的setContentView给出。

  //的setContentView（R.layout.activity_main）;    LayoutInflater吹气=（LayoutInflater）getApplicationContext（）
            .getSystemService（Context.LAYOUT_INFLATER_SERVICE）;
    查看内容查看= inflater.inflate（R.layout.activity_main，空，假）;
    drawerLayout.addView（内容查看，0）;
 

我为我的整个应用成功的做到了这一点。

快乐编码：）

I have two activities - MainActivity for user login page, and the second activity displaying user details(projects made by user) in a ListView. I want to create a Navigation Drawer Layout that will appear in both activities. I found the solution here. But the problem is, my second activity extends ListActivity to display user details in ListView, so I cannot extend anything else. here is my second activity:

public class ProjectList extends ListActivity {
ArrayList<String> listItems = new ArrayList<String>();
ArrayAdapter<String> adapter;
ListView listView;
JSONArray projects = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.project_list_inflator);
    listView = (ListView)findViewById(android.R.id.list);
    adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listItems);
    listView.setAdapter(adapter);
    new HttpGetHandler().execute();
}



private class HttpGetHandler extends AsyncTask<String, Void, Void> {
    String jsonUrl = "some url";
    String imgUrl = "http://canvasflip.com/protected/app/elements/userElements/";
    @Override
    protected Void doInBackground(String... params) {
        HttpGet httpGet = new HttpGet(jsonUrl);
        //HttpGet httpGet1 = new HttpGet(imgUrl);
        try {
            HttpResponse httpResponse = MainActivity.httpClient.execute(httpGet);
            HttpEntity httpEntity = httpResponse.getEntity();
            InputStream content = httpEntity.getContent();
            String result = convertToString(content);
            JSONObject jsonObject = new JSONObject(result);
            projects = jsonObject.getJSONArray("projects");
            ProjectList.this.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    try {
                        for(int i = 0; i<projects.length(); i++) {
                            JSONObject p = projects.getJSONObject(i);
                            String title = p.getString("title");
                            listItems.add(title);
                            adapter.notifyDataSetChanged();
                        }

                    }catch(Exception e) {
                        Log.d("MSG", e.toString());
                    }
                }
            });
        }catch(Exception e) {
            System.out.println(e.getMessage());
        }
        return null;
    }

    public String convertToString(InputStream inputStream) throws IOException {
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
        String line = "";
        String result = "";
        while((line = bufferedReader.readLine())!=null) {
            result += line;

        }
        inputStream.close();
        return result;
    }
 }
}

解决方案

just make a new Activity that has the source of Navigation drawer implementaion

like public class DrawerActivity extends ListActivity Override the DrawerLayout as

protected DrawerLayout drawerLayout;

in onCreate of your drawer Activity initialize the drawer layout as,

drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout1);

And let your MainActivity extends the DrawerAcivity.

then replace the setContentView as given.

//  setContentView(R.layout.activity_main);

    LayoutInflater inflater = (LayoutInflater) getApplicationContext()
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View contentView = inflater.inflate(R.layout.activity_main, null, false);
    drawerLayout.addView(contentView, 0);

I have done this for my whole application successfully.

happy coding :)
