Question

我已经调整了我的应用程序以使用SherlockActivity但是因为我已经这样做了，所以我无法在网格视图上触发任何点击。下面是xml：

<?xml version="1.0" encoding="utf-8"?>

    <RelativeLayout
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
       android:background="@android:color/white">

        <GridView
            android:id="@+id/dashboard_grid"
            style="@style/dashboard"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:listSelector="@android:color/transparent"
            android:stretchMode="columnWidth"
            android:verticalSpacing="20.0dip" />

    </RelativeLayout>

我的onCreate方法：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.grid);

    final ImageAdapter imageAdpt = new ImageAdapter(this);

    GridView gridview = (GridView) findViewById(R.id.dashboard_grid);
    gridview.setAdapter(imageAdpt);

    gridview.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            Toast.makeText(MainActivity.this, "" + position, Toast.LENGTH_SHORT).show();
            Class<?> c = imageAdpt.getImageClass(position);
            if(c != null){
                Intent intent = new Intent(MainActivity.this, c);
                startActivity(intent);
            }
        }
    });
}

它是否必须对焦点做任何事情？

嗨毕竟我以前从剩下的菜单中充气！

 public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getSupportMenuInflater();
    inflater.inflate(R.menu.mainmenu, menu);
}

我将其替换为：

public boolean onCreateOptionsMenu(Menu menu) {


   menu.add("Search")
       .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_WITH_TEXT);
   return true;
}

使用GridView和onItemClick进行SherlockActivity
