我正在尝试找出如何在多个活动中包含常见的代码片段。
更具体地说,我有一个上下文菜单,我希望在几个活动中使用它。 我看到了这个链接,但不知道如何扩展到多个活动。 http://developer.android.com/guide/topics/ui/menus.html
我已将其设置为Menu.java。
public class Menu extends Activity{
// bottom menus
public static final int Menu1 = 1;
public static final int Menu2 = 2;
public static final int Menu3 = 3;
public static final int Menu4 = 4;
public static final int Menu5 = 5;
public static final int Menu6 = 6;
public static final int Menu7 = 7;
// / Creates the menu items
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(0, Menu3, 0, "Create Profile").setIcon(
this.getResources().getDrawable(R.drawable.ic_menu_add));
menu.add(0, Menu5, 0, "Log In").setIcon(
this.getResources().getDrawable(R.drawable.ic_menu_login));
menu.add(0, Menu2, 0, "Settings").setIcon(
this.getResources().getDrawable(R.drawable.ic_menu_preferences));
menu.add(0, Menu4, 0, "About").setIcon(
this.getResources().getDrawable(R.drawable.ic_menu_help));
menu.add(0, Menu1, 0, "Report A Bug").setIcon(
this.getResources().getDrawable(R.drawable.ic_menu_start_conversation));
menu.add(0, Menu6, 0, "New Stuff").setIcon(
this.getResources().getDrawable(R.drawable.ic_menu_view));
return true;
}
private MenuItem add(int i, int menu32, int j, String string) {
// TODO Auto-generated method stub
return null;
}
// Handles item selections from preference menu
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case Menu1:
startActivity(new Intent(this, Bug.class));
return true;
case Menu2:
startActivity(new Intent(this, EditPreferences.class));
return true;
case Menu3:
startActivity(new Intent(this, CreateAccount.class));
return true;
case Menu4:
startActivity(new Intent(this, About.class));
return true;
case Menu5:
startActivity(new Intent(this, Login.class));
return true;
case Menu6:
startActivity(new Intent(this, NewAdditions.class));
return true;
}
return false;
}
}

中声明BaseActivity吗?还是不需要? - Ahmed Nawaz
