多窗格中的 "Gridview Images" 和 "Full screen" 片段 (android)

Question

我是新来的android..我的英语一点:( 我想开发多窗格应用程序。两个片段 "Gridview" 和 "Full screen" 我知道多窗格，但我不知道多窗格中的 Gridview 和全屏。因为 ListView 的所有示例。请帮助我

这个应用程序很适合我，但太复杂了= http://www.codeproject.com/Articles/779293/Building-Dynamic-UI-for-Android-Devices

Answer 1

如果我正确理解你的问题，这是一个简单的实现

------------ 创建 GridView ------------

对于 GridView，您需要一个用于 GridView 对象的适配器和用于列的图像，例如使用国家/地区列表和国旗图像，

在 res 中创建可绘制文件夹并在可绘制文件夹中添加国旗图像

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.javaclass
```
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;
        } 
```
}
1. 创建片段 GridViewActivty
public class GridViewActivty 扩展 Fragment { private ArrayList CountryList = new ArrayList(); private ArrayList CountryFlag = new ArrayList(); 私有 GridView mygrid；私有 GridAdapter 适配器；私有上下文上下文； public GridViewActivty(){} @覆盖 public 查看 onCreateView(LayoutInflater inflater, ViewGroup 容器，Bundle savedInstanceState） { 查看 rootView = inflater.inflate(R.layout.gridlayout.xml, container, false);</p> <pre><code> 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 --------
```

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>

>

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; }
