1. listview的简单使用（弃）

                   // Creat a list of HashMap to get the datas shows on listview
                   ArrayList> mArrayList = new ArrayList>();
                   int mId = 0;
                   for(result mResult : fList_result){

                       HashMap map = new HashMap();
                       map.put("Desc",mResult.getDesc());
                       map.put("Date",mResult.getPublishedAt());
                       map.put("Who",mResult.getWho());
                       map.put("Id",(++mId) +"");
                       mArrayList.add(map);
                   }

                   
                   mSimpleAdapter = new SimpleAdapter(
                       getContext(),
                       mArrayList,
                       R.layout.listview_dataitem,
                       new String[] {"Desc","Date","Who","Id"},
                       new int[] {R.id.listview_dataitem_descText,
                           R.id.listview_dataitem_datetext,
                           R.id.listview_dataitem_whotext,
                           R.id.listview_dataitem_IdText});

                   mListView.setAdapter(mSimpleAdapter);

                   mListView.setOnItemClickListener(new OnItemClickListener(){

                           @Override
                           public void onItemClick(AdapterView p1, View p2, int p3, long p4)
                           {
                               LinearLayout l = (LinearLayout) p2;
                               TextView t = (TextView)l.findViewById(R.id.listview_dataitem_descText);

                               for(result resultb :fList_result){
                                   if(resultb.getDesc().equals(t.getText().toString()))
                                       openWebWindow(resultb.getUrl());
                               }


                               // TODO: Implement this method
                           }
                       });
                       

2. sugar的简单使用

3. okhttp3的简单使用

4. DialogFragment

5. recyclerview的简单使用

• 导包：

 compile 'com.squareup.okhttp3:okhttp:3.6.0'

//用于转化实例
 compile 'com.google.code.gson:gson:2.2.4'
    

• 获取Call

    @Override
    public Call getGankArticle(String type, int page)
    {

        //new a Call by using okhttp3 
        //and return it.
        
        String mBaseUrl = "http://gank.io/api/";

        final String NUM_PER_PAGE = "10";

        OkHttpClient mOkHttpClient = new OkHttpClient();
        Request.Builder builder = new Request.Builder().url(mBaseUrl +"data/" + type +"/" + NUM_PER_PAGE + "/" + page);

        final Request request =builder.build();

        Call mCall = mOkHttpClient.newCall(request);
        
        // TODO: Implement this method
        return mCall;
    }

• 额..不知道怎么分

    @Override
    public void loadArticle(String type, int page)
    {
                
        Call mCall = mModelImpl.getGankArticle(type,page);
        mCall.enqueue(new Callback(){

                @Override
                public void onFailure(Call p1, IOException p2)
                {
                    
                    // TODO: Implement this method
                }

                @Override
                public void onResponse(Call p1, Response p2) throws IOException
                {
                    DataEntity mDE = new Gson().fromJson(p2.body().string(),DataEntity.class);
                    Log.i("test",""+mDE.getResults().size());
                    mView.addViews(mDE.getResults());
                    // TODO: Implement this method
                }
            });

4. Navigation的简单使用

在activity 中实现：

package com.kfdykme.view.navigationview;
import android.os.Bundle;
import android.support.design.widget.NavigationView;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.Toolbar;
import android.view.MenuItem;
import android.view.*;
import android.support.v4.view.*;
import android.support.v7.app.*;


public class Main extends AppCompatActivity
{

    private DrawerLayout mDrawerLayout;
    private NavigationView mNavigationView;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        
        setContentView(R.layout.main);

        mDrawerLayout = (DrawerLayout) findViewById(R.id.id_drawer_layout);
        mNavigationView = (NavigationView) findViewById(R.id.id_nv_menu);

        
        setupDrawerContent(mNavigationView);


    }

    private void setupDrawerContent(NavigationView navigationView)
    {
        navigationView.setNavigationItemSelectedListener(

            new NavigationView.OnNavigationItemSelectedListener()
            {

                @Override
                public boolean onNavigationItemSelected(MenuItem menuItem)
                {
                    menuItem.setChecked(true);
                    mDrawerLayout.closeDrawers();
                    return true;
                }
            });
    }

}

备注1

AIDE 无法使用引入了注解的库
有机会弄明白原因并尝试使用

greenDao & retrofit & maybe others need it

备注2

使用mvp模式和网络请求时，之前一直纠结于如何在model或presenter 中onResponse后再在得到返回后在view中刷新

后来发现其实可以返回一个call 然后在别处使用它

还是有点纠结，难以说清

备注3

mvp模式看了这个博客后感觉有点清晰起来了。

3.12

1. 重写KGankMainActivity的onKeyDown()方法 ：打开WebDow时按返回键判断goback。

3.13

1. Use SwipeRefreshLayout implements "Pull down refresh"
2. Implements "Pull up load more" by rewriting RecyclerView's adapter . Not so good.
