Answer 1

如果我理解你的问题，这是一个简单的实现

-------------创建GridView ------------

对于GridView，您需要一个GridView对象的适配器和列的图像，一个使用国家/地区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country flag图像

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>

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>

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;
        }

}

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;

        }

}

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; } }

在布局文件夹
中创建fullscreen.xml
```
----------- Creating Full Screen --------
```
＆GT;

创建FullScreen.java片段

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