Android UI开发第一篇——android的九宫格式实现
今天在devdiv论坛里看到有坛友问到九宫格的实现，我把我在项目中用的经验分享一下，九宫格用gridview实现代码如下：代码下载地址：http://www.devdiv.com/thread-39455-1-1.html xml代码： <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res/com.google.android.gx5weather" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1.0" android:background="@drawable/bg" > <ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:background="@drawable/top"></ImageView> <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gridview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:numColumns="3" android:verticalSpacing="30dip" android:horizontalSpacing="10dip" android:columnWidth="90dip" //列宽 android:stretchMode="columnWidth" android:gravity="center" android:listSelector="@drawable/grid_selector_background" > </GridView> </LinearLayout> android:numColumns="3" //九宫格的列数 auto_fit时为自动 android:listSelector="@drawable/grid_selector_background" //九宫格的背景，可以找个圆角正方形 public class NineBox extends Activity { /** Called when the activity is first created. */ @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); this.requestWindowFeature(Window.FEATURE_NO_TITLE); this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.main_activity); GridView gridview=(GridView)findViewById(R.id.gridview); ArrayList<HashMap<String, Object>> lstImageItem = new ArrayList<HashMap<String, Object>>(); for(int i=1;i<10;i++) { HashMap<String, Object> map = new HashMap<String, Object>(); if(i==1){ map.put("ItemImage", R.drawable.g11); map.put("ItemText", getResources().getString(R.string.gridview1)); } if(i==2){ map.put("ItemImage", R.drawable.g12); map.put("ItemText", getResources().getString(R.string.gridview2)); } if(i==3){ map.put("ItemImage", R.drawable.g13); map.put("ItemText", getResources().getString(R.string.gridview3)); } if(i==4){ map.put("ItemImage", R.drawable.g14); map.put("ItemText", getResources().getString(R.string.gridview4)); } if(i==5){ map.put("ItemImage", R.drawable.g15); map.put("ItemText", getResources().getString(R.string.gridview5)); } if(i==6){ map.put("ItemImage", R.drawable.g16); map.put("ItemText", getResources().getString(R.string.gridview6)); } if(i==7){ map.put("ItemImage", R.drawable.g17); map.put("ItemText", getResources().getString(R.string.gridview7)); } if(i==8){ map.put("ItemImage", R.drawable.g18); map.put("ItemText", getResources().getString(R.string.gridview8)); } if(i==9){ map.put("ItemImage", R.drawable.g19); map.put("ItemText", getResources().getString(R.string.gridview9)); } lstImageItem.add(map); } SimpleAdapter saImageItems = new SimpleAdapter(this, lstImageItem, R.layout.grid_item, new String[] {"ItemImage","ItemText"}, new int[] {R.id.ItemImage,R.id.ItemText}); gridview.setAdapter(saImageItems); gridview.setOnItemClickListener(new ItemClickListener()); } class ItemClickListener implements OnItemClickListener { @SuppressWarnings("unchecked") public void onItemClick(AdapterView<?> arg0,//The AdapterView where the click happened View arg1,//The view within the AdapterView that was clicked int arg2,//The position of the view in the adapter long arg3//The row id of the item that was clicked ) { HashMap<String, Object> item=(HashMap<String, Object>) arg0.getItemAtPosition(arg2); if(item.get("ItemText").equals(getResources().getString(R.string.gridview1))){ Toast.makeText(NineBox.this, R.string.gridview1, Toast.LENGTH_LONG).show(); } if(item.get("ItemText").equals(getResources().getString(R.string.gridview2))){ Toast.makeText(NineBox.this, R.string.gridview2, Toast.LENGTH_LONG).show();
