怎样去除GridView长按返回后的选中效果？？求助

装作睡不着 2014-12-29 10:21:03

是这样的，一个Gridview， android:listSelector="#123456" android:drawSelectorOnTop="true"来设置选中效果，按下后就会显示相应的效果，但是长按后弹出菜单，再按返回选中效果没有消失，这时怎么回事，求大神指点。图片如下

XML代码：<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >

<TextView
android:id="@+id/equalizerText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="均衡器"/>

<GridView
android:id="@+id/equalizerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:numColumns="4"
android:horizontalSpacing="5dp"
android:verticalSpacing="5dp"
android:listSelector="#123456"
android:drawSelectorOnTop="true">
</GridView>

Java代码：

public class MainActivity extends Activity {

	private GridView equalizerView;

	private int select_position=1;

	private int a;

	SimpleAdapter simpleAdapter;

	String [] E = {"正常","古典","舞曲","平直",

			       "民歌","重金属","嘻哈","爵士",

			       "流行","摇滚","增强器","自定义"};

	int [] ID = {R.drawable.classical,

			     R.drawable.custom,

			     R.drawable.dance_song,

			     R.drawable.enhancer,

			     R.drawable.flat,

			     R.drawable.folk_song,

			     R.drawable.heavy_metal,

			     R.drawable.hip_hop,

			     R.drawable.jazz,

			     R.drawable.normal,

			     R.drawable.rock_and_roll,

			     R.drawable.pop};

@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		// requestWindowFeature(Window.FEATURE_NO_TITLE);

		setContentView(R.layout.switch_layout);

		

		equalizerView=(GridView) findViewById(R.id.equalizerView);

		 registerForContextMenu(equalizerView);

ArrayList<HashMap<String, Object>> imagelist = new ArrayList<HashMap<String, Object>>();

		for (int i = 0; i < 12; i++) {

		      HashMap<String, Object> map = new HashMap<String, Object>();

		      map.put("image", ID[i]);

		      map.put("text", E[i]);

		     imagelist.add(map);

		    }

		simpleAdapter = new SimpleAdapter(this, imagelist,

			        R.layout.grid_item, new String[] { "image", "text" }, new int[] {

			            R.id.item_image, R.id.item_text});

		equalizerView.setAdapter(simpleAdapter);

 @Override                                                                                                              

	    public void onCreateContextMenu(final ContextMenu menu, final View v,final ContextMenuInfo menuInfo) {                                                                              

	        super.onCreateContextMenu(menu, v, menuInfo);                                                                      

	        final AdapterContextMenuInfo info = (AdapterContextMenuInfo) menuInfo;                                             

	            menu.setHeaderTitle("wuwuw");                                                                            

	            menu.add(0,1, 0,"a");                                                              

	            menu.add(0,2, 0,"b");                                                          

	    }             

	}

由于代码比较多，这只是部分代码，请谅解。其实不用看代码，有遇见过这类问题的朋友，给我点思路方法就行。感激不尽！！
