android菜谱例子(入门级示例)

菜谱：一个界面为菜单，一个界面为菜品做法

ContentFragment.java的代码:

package cn.itcast.sichuancuisine; import android.app.Activity; import android.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; public class ContentFragment extends Fragment { private View view; private TextView mContent; @Override  public void onAttach(Activity activity) { super.onAttach(activity);
    } @Override  public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) { //将布局文件解析出来  view = inflater.inflate(R.layout.fragment_content, container, false); if(view != null){ //如果view不为空  initView();
        } //获取Activity中的设置文字  Caipin caipin=new Caipin();
        String[] text=caipin.getSettingText();
        setText(text[0]); return view;
    } public void initView(){ mContent = (TextView) view.findViewById(R.id.content);
    } public void setText(String text){ mContent.setText(text);
    }
}
MenuFragment.java的代码

package cn.itcast.sichuancuisine; import android.annotation.SuppressLint; import android.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.ListView; import android.widget.TextView; @SuppressLint("NewApi") public class MenuFragment extends Fragment { private View view; private int[] settingicon; private String[] foodNames; private String[] settingText; private ListView mListView; @Override  public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) { //解析布局  view = inflater.inflate(R.layout.fragment_menu, container, false); //获取Caipim实例对象   Caipin caipin=new Caipin(); //获取caipin中的图标数组  settingicon = caipin.getIcons(); //获取caipin中定义的川菜名称  foodNames =  caipin.getNames(); //获取caipin中的设置文字数组  settingText = caipin.getSettingText(); if (view != null) { // 如果view不为空  initView();
        } //为ListView设置条目监听  mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override  public void onItemClick(AdapterView<?> parent, View view,int position, long id) { //点击左侧的川菜列表item，右侧菜品做法内容相应改变逻辑  //通过Activity实例获取另一个Fragment实例  ContentFragment listFragment = (ContentFragment)((MainActivity)
                        getActivity()).getFragmentManager().findFragmentById(R.id.foodcontent); //设置菜品类表点击位置对应的菜品做法的Fragment文字  listFragment.setText(settingText[position]);
            }
        }); return view;
    } //初始化控件的方法  private void initView() { mListView = (ListView) view.findViewById(R.id.menulist); if (settingicon != null) { mListView.setAdapter(new MyAdapter());
        }
    } //适配器  class MyAdapter extends BaseAdapter { @Override  public int getCount() { return settingicon.length;
        } @Override  public Object getItem(int position) { return settingicon[position];
        } @Override  public long getItemId(int position) { return position;
        } @Override  public View getView(int position, View convertView, ViewGroup parent) {
            convertView = View.inflate(getActivity(), R.layout.item_list, null);
            ImageView mNameTV = (ImageView) convertView
                    .findViewById(R.id.food_icon);
            mNameTV.setBackgroundResource(settingicon[position]);
            TextView mFoodName = (TextView) convertView.findViewById
                    (R.id.food_name);
            mFoodName.setText(foodNames[position]); return convertView;
        }
    }
}
