我正在使用像滑动菜单这样的Facebook,但我遇到一个小问题,不知道如何在每个活动中添加滑动菜单,就像在PrincipalActivity中显示菜单一样:
PrincipalActivity.java:
public class PrincipalActivity extends Activity {
public static final String ID = "id";
public static final String ICON = "icon";
public static final String TITLE = "title";
public static final String DESCRIPTION = "description";
private RelativeLayout layout;
private MenuLazyAdapter menuAdapter;
private boolean open = false;
private final Context context = this;
private ListView listMenu;
private TextView appName;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.principal);
this.listMenu = (ListView) findViewById(R.id.listMenu);
this.layout = (RelativeLayout) findViewById(R.id.layoutToMove);
this.appName = (TextView) findViewById(R.id.appName);
this.menuAdapter = new MenuLazyAdapter(this, MenuEventController.menuArray.size() == 0 ? MenuEventController.getMenuDefault(this) : MenuEventController.menuArray);
this.listMenu.setAdapter(menuAdapter);
this.layout.setOnTouchListener(new OnSwipeTouchListener() {
public void onSwipeRight() {
if(!open){
open = true;
MenuEventController.open(context, layout, appName);
MenuEventController.closeKeyboard(context, getCurrentFocus());
}
}
public void onSwipeLeft() {
if(open){
open = false;
MenuEventController.close(context, layout, appName);
MenuEventController.closeKeyboard(context, getCurrentFocus());
}
}
});
this.listMenu.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//Your intent object is null, you need set a intent to this object,
//like in 0 position
Intent intent = null;
if(position == 0){
//action
//Here you need create the intent
//LOOK
intent = new Intent(PrincipalActivity.this, org.shipp.activity.Test.class);
} else if(position == 1){
//action
//Here you need create the intent
intent = new Intent(PrincipalActivity.this, org.shipp.activity.Test2.class);
} else if(position == 2){
//if activity is this just close menu before verify if menu is open
if(open){
open = false;
MenuEventController.close(context, layout, appName);
MenuEventController.closeKeyboard(context, view);
}
} else if(position == 3){
//Here you need create the intent
//intent = new Intent(this, MyNewActivity3.class);
} else if(position == 4){
//Here you need create the intent
//intent = new Intent(this, MyNewActivity4.class);
} else if(position == 5){
//Here you need create the intent
//intent = new Intent(this, MyNewActivity5.class);
} else if(position == 6){
//Here you need create the intent
//intent = new Intent(this, MyNewActivity6.class);
} else if(position == 7){
//Here you need create the intent
//intent = new Intent(this, MyNewActivity7.class);
}
//Check the position if different of current a intent are started else menu just closed
if(position != 2){
startActivity(intent);
PrincipalActivity.this.finish();
overridePendingTransition(R.anim.slide_left, R.anim.slide_left);
}
}
});
}
public void openCloseMenu(View view){
if(!this.open){
this.open = true;
MenuEventController.open(this.context, this.layout, this.appName);
MenuEventController.closeKeyboard(this.context, view);
} else {
this.open = false;
MenuEventController.close(this.context, this.layout, this.appName);
MenuEventController.closeKeyboard(this.context, view);
}
}
}
principal.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/menu_bg"
tools:context=".PrincipalActivity" >
<include layout="@layout/actionbar_menu" android:id="@+id/actionBarMenu"/>
<ListView
android:id="@+id/listMenu"
android:layout_below="@+id/actionBarMenu"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#282828"
android:dividerHeight="1dip"
android:background="#3F3F3F"
android:fadingEdge="none"
android:listSelector="@drawable/list_selector">
</ListView>
<RelativeLayout
android:id="@+id/layoutToMove"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="@+id/actionBar"
android:background="#282828">
<include layout="@layout/actionbar_layout" android:id="@+id/actionBar"/>
<ImageButton
android:id="@+id/menuButton"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_alignBottom="@+id/actionBar"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:onClick="openCloseMenu"
android:src="@drawable/menu"
android:background="@android:color/transparent" />
<Button
android:id="@+id/separator"
android:layout_width="1dp"
android:layout_height="50dp"
android:layout_toRightOf="@+id/menuButton"
android:background="@drawable/custom_button_black" />
</RelativeLayout>
</RelativeLayout>
在测试活动中我还想显示滑动菜单
Test.java:
public class Test extends PrincipalActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
}
}
的test.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="186dp"
android:text="Test" />
</RelativeLayout>
所以请告诉我我的代码应该是什么样的,我需要在我的所有活动中添加哪些代码来显示滑动菜单。
答案 0 :(得分:2)
我想你可能想重新考虑你的设计。我为使用滑动菜单的客户制作了不少商业应用程序。在这样的应用程序中,我通常有一个中心活动,其他所有内容都是片段,活动本身可能有标题栏,标签或菜单,或者没有,但所有复杂的视图都是片段。通常,您希望让活动在所有具有相同功能的屏幕中实现最常见的视图和控件,无论如何。
如果你真的必须这样做,我建议制作一个父类来处理所有的滑动功能,让你的活动需要从中继承滑动功能。
在任何情况下,您都希望使用片段,无论是来自支持库,还是目标API都足够高,只需要常规片段。
然后您应该研究的是片段事务动画,以及更改片段视图的位置。
答案 1 :(得分:0)
你们所有人都达到了,代码中需要进行一些更改......
第1步:保持您的超级活动(PrincipalActivity
)仅包含菜单ID(actionbar_layout的ID)和元素(删除相对布局,列表视图等ID)
第2步:删除超级活动中的on create方法(PrincipalActivity
)...
setp 3:创建一个名为initmenu
的方法,并在该方法中初始化视图
public void initmenu(){
this.listMenu = (ListView) findViewById(R.id.listMenu);
...
}
第4步:在测试活动中使用setContetView(R.layout.principal);
第5步:在测试活动中的setcontet视图之后调用initmenu()方法...你现在差不多完成了......你可以处理更多的更改:)
