In effetti, c'è un modo per farlo. Anche senza implementare il tuo ActionBar.
Dai un'occhiata al hierachyviewer! (Situato nella directory degli strumenti)
C'è il DecorView, e un LinearLayoutda bambino. Questo LinearLayoutcontiene sia il ActionBarcontenuto che l'altro. Quindi, puoi semplicemente applicarne un po ' FrameLayout.LayoutParamsa questo LinearLayoute ottenere un po' di spazio sul lato sinistro in questo modo. Quindi, puoi riempire questo spazio con il tuo menu-ListView e sovrapporre l'altro contenuto con un FrameLayout, che, quando viene cliccato, comprime il menu. Quindi, ecco un po 'di codice:
Innanzitutto, la classe per la compressione / espansione (SlideMenu.java):
package your.cool.app;

import android.graphics.Rect;

public class SlideMenu {
//just a simple adapter
public static class SlideMenuAdapter extends ArrayAdapter<SlideMenu.SlideMenuAdapter.MenuDesc> {

SlideMenu.SlideMenuAdapter.MenuDesc[] items;
class MenuItem {
public TextView label;
public ImageView icon;
}
static class MenuDesc {
public int icon;
public String label;
}
public SlideMenuAdapter(Activity act, SlideMenu.SlideMenuAdapter.MenuDesc[] items) {
super(act, R.id.menu_label, items);
this.act = act;
this.items = items;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
if (rowView == null) {
LayoutInflater inflater = act.getLayoutInflater();
rowView = inflater.inflate(R.layout.menu_listitem, null);
MenuItem viewHolder = new MenuItem();
viewHolder.label = (TextView) rowView.findViewById(R.id.menu_label);
viewHolder.icon = (ImageView) rowView.findViewById(R.id.menu_icon);
rowView.setTag(viewHolder);
}
MenuItem holder = (MenuItem) rowView.getTag();
String s = items[position].label;
holder.label.setText(s);
holder.icon.setImageResource(items[position].icon);
return rowView;
}
}
private static boolean menuShown = false;
private static View menu;
private static LinearLayout content;
private static FrameLayout parent;
private static int menuSize;
private static int statusHeight = 0;
private Activity act;
SlideMenu(Activity act) {
this.act = act;
}
//call this in your onCreate() for screen rotation
public void checkEnabled() {
if(menuShown)
this.show(false);
}
public void show() {
//get the height of the status bar
if(statusHeight == 0) {
Rect rectgle = new Rect();
Window window = act.getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(rectgle);
statusHeight = rectgle.top;
}
this.show(true);
}
public void show(boolean animate) {
menuSize = Functions.dpToPx(250, act);
content = ((LinearLayout) act.findViewById(android.R.id.content).getParent());
FrameLayout.LayoutParams parm = (FrameLayout.LayoutParams) content.getLayoutParams();
parm.setMargins(menuSize, 0, -menuSize, 0);
content.setLayoutParams(parm);
//animation for smooth slide-out
TranslateAnimation ta = new TranslateAnimation(-menuSize, 0, 0, 0);
ta.setDuration(500);
if(animate)
content.startAnimation(ta);
parent = (FrameLayout) content.getParent();
LayoutInflater inflater = (LayoutInflater) act.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
menu = inflater.inflate(R.layout.menu, null);
FrameLayout.LayoutParams lays = new FrameLayout.LayoutParams(-1, -1, 3);
lays.setMargins(0,statusHeight, 0, 0);
menu.setLayoutParams(lays);
parent.addView(menu);
ListView list = (ListView) act.findViewById(R.id.menu_listview);
list.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//handle your menu-click
}
});
if(animate)
menu.startAnimation(ta);
menu.findViewById(R.id.overlay).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
SlideMenu.this.hide();
}
});
Functions.enableDisableViewGroup((LinearLayout) parent.findViewById(android.R.id.content).getParent(), false);
((ExtendedViewPager) act.findViewById(R.id.viewpager)).setPagingEnabled(false);
((ExtendedPagerTabStrip) act.findViewById(R.id.viewpager_tabs)).setNavEnabled(false);
menuShown = true;
this.fill();
}
public void fill() {
ListView list = (ListView) act.findViewById(R.id.menu_listview);
SlideMenuAdapter.MenuDesc[] items = new SlideMenuAdapter.MenuDesc[5];
//fill the menu-items here
SlideMenuAdapter adap = new SlideMenuAdapter(act, items);
list.setAdapter(adap);
}
public void hide() {
TranslateAnimation ta = new TranslateAnimation(0, -menuSize, 0, 0);
ta.setDuration(500);
menu.startAnimation(ta);
parent.removeView(menu);
TranslateAnimation tra = new TranslateAnimation(menuSize, 0, 0, 0);
tra.setDuration(500);
content.startAnimation(tra);
FrameLayout.LayoutParams parm = (FrameLayout.LayoutParams) content.getLayoutParams();
parm.setMargins(0, 0, 0, 0);
content.setLayoutParams(parm);
Functions.enableDisableViewGroup((LinearLayout) parent.findViewById(android.R.id.content).getParent(), true);
((ExtendedViewPager) act.findViewById(R.id.viewpager)).setPagingEnabled(true);
((ExtendedPagerTabStrip) act.findViewById(R.id.viewpager_tabs)).setNavEnabled(true);
menuShown = false;
}
}
Alcuni metodi di aiuto (per me, in Functions.java statico):
public static int dpToPx(int dp, Context ctx) {
Resources r = ctx.getResources();
return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp, r.getDisplayMetrics());
}
//originally: http://stackoverflow.com/questions/5418510/disable-the-touch-events-for-all-the-views
//modified for the needs here
public static void enableDisableViewGroup(ViewGroup viewGroup, boolean enabled) {
int childCount = viewGroup.getChildCount();
for (int i = 0; i < childCount; i++) {
View view = viewGroup.getChildAt(i);
if(view.isFocusable())
view.setEnabled(enabled);
if (view instanceof ViewGroup) {
enableDisableViewGroup((ViewGroup) view, enabled);
} else if (view instanceof ListView) {
if(view.isFocusable())
view.setEnabled(enabled);
ListView listView = (ListView) view;
int listChildCount = listView.getChildCount();
for (int j = 0; j < listChildCount; j++) {
if(view.isFocusable())
listView.getChildAt(j).setEnabled(false);
}
}
}
}
Quindi, i layout:
Layout del menu (res / layout / menu.xml)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:orientation="vertical"
android:layout_height="fill_parent"
android:layout_width="250dip"
android:background="@color/darkblack">
<ListView
android:id="@+id/menu_listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="@color/dividerblack"
android:dividerHeight="2dip" />
</LinearLayout>
<FrameLayout
android:id="@+id/overlay"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
</LinearLayout>
Layout degli elementi list (res / layout / menu_listitem.xml):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="fill_parent" >
<ImageView
android:id="@+id/menu_icon"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_marginRight="5dip"
android:layout_marginLeft="10dip"
android:layout_marginTop="10dip"
android:layout_marginBottom="10dip" />
<TextView
android:id="@+id/menu_label"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="@color/white"
android:textSize="24dp"
android:layout_marginTop="10dip"
android:layout_marginBottom="10dip" />
</LinearLayout>
Come usarlo:
Nel tuo onCreate():
private SlideMenu slidemenu;
@Override
public void onCreate(Bundle savedInstanceState) {
//your onCreate code
slidemenu = new SlideMenu(this);
slidemenu.checkEnabled();
}
Nel gestore del pulsante home di ActionBar:
slidemenu.show();
Questo è tutto!
E ora, un piccolo screenshot in azione:
Per quanto ne so, funziona. Se riscontri problemi o le mie spiegazioni non sono chiare, contattami!
MODIFICA: ExtendedViewPager& ExtendedPagerStrip:
ExtendedViewPager:
package your.cool.app;
//source: http://blog.svpino.com/2011/08/disabling-pagingswiping-on-android.html
import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;
public class ExtendedViewPager extends ViewPager {
private boolean enabled;
public ExtendedViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
this.enabled = true;
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onTouchEvent(event);
}
return false;
}
@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onInterceptTouchEvent(event);
}
return false;
}
public void setPagingEnabled(boolean enabled) {
this.enabled = enabled;
}
}
ExtendedPagerTabStrip:
package your.cool.app;
//source: http://blog.svpino.com/2011/08/disabling-pagingswiping-on-android.html
import android.content.Context;
import android.support.v4.view.PagerTabStrip;
import android.util.AttributeSet;
import android.view.MotionEvent;
public class ExtendedPagerTabStrip extends PagerTabStrip {
private boolean enabled;
public ExtendedPagerTabStrip(Context context, AttributeSet attrs) {
super(context, attrs);
this.enabled = true;
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onTouchEvent(event);
}
return false;
}
@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onInterceptTouchEvent(event);
}
return false;
}
public void setNavEnabled(boolean enabled) {
this.enabled = enabled;
}
}
Io uso questo SlideMenuper un'attività con un ViewPagercon PagerTabStripper le schede come Talk, mercato, ecc Non è possibile disabilitare questi punti di vista in modo semplice, per cui le due classi di cui sopra solo estendono loro di fermare l' onTouchevento quando disattivato.
