android - 多窗格中的“Gridview Images”和“全屏”片段（android）

Question

我是新的android..我的英语一点点:(我想开发多窗格应用程序。两个片段“Gridview”和“全屏” 我知道多窗格，但我不知道多窗格中的Gridview和全屏。因为所有示例对于 ListView。请帮帮我

这个应用程序对我很好，但太复杂了= http://www.codeproject.com/Articles/779293/Building-Dynamic-UI-for-Android-Devices

Answer 1

如果我正确理解您的问题，这是一个简单的实现

------------- 创建 GridView ------------

1. 对于 GridView，您需要 GridView 对象的适配器和列的图像，使用国家列表和标志图像的示例，

在 res 中创建 drawable 文件夹并在 drawable 文件夹中添加国旗图像

2. 在 res/layout 中创建 gridlayout.xml

      <RelativeLayout  
       android:id="@+id/relativeLayout1"
       android:layout_width="fill_parent" 
       android:layout_height="fill_parent"
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:background="@drawable/border"
       android:padding="5dp">
   
       <ImageView 
       android:id="@+id/gridimage" 
       android:layout_height="65dp" 
           android:layout_width="65dp" 
           android:src="@drawable/icon" 
           android:layout_alignParentTop="true" 
           android:layout_centerHorizontal="true">
       </ImageView>
   
       <TextView 
           android:id="@+id/gridtext"
           android:text="TextView" 
           android:layout_height="wrap_content"
           android:layout_width="wrap_content"
           android:layout_below="@+id/imageView1" 
           android:layout_marginTop="2dp"
           android:layout_centerHorizontal="true"
           android:textSize="18sp"
           android:ellipsize="marquee"></TextView>
   
   </RelativeLayout>
   

3. 在 res/Layout 文件夹中创建 gridrow.xml

   <GridView 
       android:id="@+id/gridView1" 
       android:layout_height="wrap_content" 
       android:layout_width="match_parent" 
       android:numColumns="auto_fit"
       android:horizontalSpacing="10dp"
       android:verticalSpacing="10dp">
   </GridView>
   

4. 创建 GridAdapter.java 类

   public class GridAdapter extends BaseAdapter { 
       private ArrayList<String> CountryList;
               private ArrayList<Integer> CountryFlag;
               private Activity activity;
               public GridAdapter(Activity activity,ArrayList<String> CountryList, ArrayList<Integer> CountryFlag){
   super();this.CountryList = CountryList;
               this.CountryFlag = CountryFlag;
               this.activity = activity;}
       @Override
           public int getCount() {
               return CountryList.size();
           }
   
           @Override
           public String getItem(int position) {
               return CountryList.get(position);
           }
   
           @Override
           public long getItemId(int position) {
               return 0;
           }
   
           public static class ViewHolder
           {
               public ImageView imgViewFlag;
               public TextView txtViewTitle;
           }
   
           @Override
           public View getView(int position, View convertView, ViewGroup parent) {
               ViewHolder view;
               LayoutInflater inflator = activity.getLayoutInflater();
   
               if(convertView==null)
               {
                   view = new ViewHolder();
                   convertView = inflator.inflate(R.layout.gridview_row, null);
   
                   view.txtViewTitle = (TextView) convertView.findViewById(R.id.gridtext);
                   view.imgViewFlag = (ImageView) convertView.findViewById(R.id.gridimage);
   
                   convertView.setTag(view);
               }
               else
               {
                   view = (ViewHolder) convertView.getTag();
               }
   
               view.txtViewTitle.setText(CountryList.get(position));
               view.imgViewFlag.setImageResource(CountryFlag.get(position));
   
               return convertView;
           } 
   

   }

   5. 创建片段 GridViewActivty

   public class GridViewActivty extends Fragment { private ArrayList CountryList = new ArrayList(); private ArrayList CountryFlag = new ArrayList(); private GridView mygrid; private GridAdapter adapter; private Context context; public GridViewActivty(){} @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.gridlayout.xml, container, false);

             CountryList = new ArrayList<String>();
             CountryList.add("South Africa");
             CountryList.add("Spain");
             CountryList.add("Canada");
             CountryList.add("China");
             CountryList.add("France");
             CountryList.add("Germany");
             CountryList.add("Iran");
             CountryList.add("Italy");
             CountryList.add("Japan");
             CountryList.add("Korea");
             CountryList.add("Mexico");  
             CountryList.add("Netherlands");
             CountryFlag = new ArrayList<Integer>();
                 CountryFlag.add(R.drawable.southafrica);
                 CountryFlag.add(R.drawable.spain);
                 CountryFlag.add(R.drawable.canada);
                 CountryFlag.add(R.drawable.china);
                 CountryFlag.add(R.drawable.france);
                 CountryFlag.add(R.drawable.germany);
                 CountryFlag.add(R.drawable.iran);
                 CountryFlag.add(R.drawable.italy);
                 CountryFlag.add(R.drawable.japan);
                 CountryFlag.add(R.drawable.korea);
                 CountryFlag.add(R.drawable.mexico);
                 CountryFlag.add(R.drawable.netherlands);
                adapter = new GridAdapter(this.getActivity(),CountryList, CountryFlag);
   
           mygrid = (GridView)rootView.findViewById(R.id.gridview1);
   
           mygrid.setAdapter(adapter);
           mygrid.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener()
           {
               @Override
               public void onItemClick(AdapterView<?> arg0, View arg1, int position,
                       long arg3) {
                   // TODO Auto-generated method stub
   
               }
           }
                   );
           return rootView;
   
           }
   
   }
   

   ----------- Creating Full Screen --------
   

5. 在布局文件夹中创建 fullscreen.xml

       <RelativeLayout
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent">
   </RelativeLayout>    
   

   >

6. 创建 FullScreen.java 片段

    public class Fullscreen extends Fragment{    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle 
            savedInstanceState)    
   { View rootView = inflater.inflate(R.layout.fullscreen.xml, container, false);
            requestWindowFeature(Window.FEATURE_NO_TITLE);
   
           getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
   
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
   
               }
   
           return convertView; }
