Android uses Popupwindow to bring up more menus

Recently want to do a popup more menu, and the original pop-up menu is not the effect we want, so it is necessary to customize the menu. I also learn from the information on the web for encapsulation, it feels pretty good.

Native menus such as:

After customization:

is not seen here after the contrast, the original effect is not ideal, so still define it yourself!

1, Popupwindow can be said to be a floating on the activity of the container, usually used to display a custom view. Package Popmenumore for pop-up menus

2. The adapter of the ListView in the menu: Popmenumoreadapter

/** * @author Soban * @create 2017/4/12 10:29.    */public class Popmenumoreadapter extends Baseadapter {private arraylist<popmenumoreitem> items;    Private context context;        Public Popmenumoreadapter (context context, arraylist<popmenumoreitem> items) {This.context = context;    This.items = items;    } @Override public int getcount () {return items.size ();    } @Override public Popmenumoreitem getItem (int position) {return items.get (position);    } @Override public long getitemid (int position) {return position; } @Override public View getView (int position, view view, ViewGroup parent) {if (view = = null) {V            Iew = Layoutinflater.from (context). Inflate (R.layout.item_popmenu_more, NULL);            Viewholder holder = new Viewholder ();            Holder.icon = (ImageView) View.findviewbyid (R.id.menu_icon);            Holder.text = (TextView) View.findviewbyid (R.id.menu_text); view.seTtag (holder);        } else if (view.getparent () = null) {((ViewGroup) view.getparent ()). Removeview (view);        } Viewholder holder = (viewholder) view.gettag ();        Popmenumoreitem item = items.get (position);        if (item.getresid () = = 0) {holder.icon.setVisibility (view.gone);        } holder.text.setText (Item.gettext ());    return view;        } private class Viewholder {ImageView icon;    TextView text; }}

4. Item:popmenumoreitem in the menu item

/** * menu item. */public class Popmenumoreitem {public    int id;//Identity public    int resId;//resource icon public    String text;//Text    Pub LIC popmenumoreitem (int id, String text) {        this.id = ID;        This.resid = 0;        This.text = text;    }    public Popmenumoreitem (int id, int resId, String text) {        this.id = ID;        This.resid = resId;        This.text = text;    }    public int getId () {        return ID;    }    public void setId (int id) {        this.id = ID;    }    public int Getresid () {        return resId;    }    public void Setresid (int resId) {        this.resid = resId;    }    Public String GetText () {        return text;    }    public void SetText (String text) {        this.text = text;    }}

4. Width adaptation content, non-scrolling Listview:popmenumorelistview

/** * Width Adaptation content of the ListView. * AUTHOR:MSDX ([email protected]) * time:14-9-2 pm 5:14 */public Class Popmenumorelistview extends ListView {pub    Lic Popmenumorelistview (Context context) {super (context);    } public Popmenumorelistview (context context, AttributeSet Attrs) {Super (context, attrs); } public Popmenumorelistview (context context, AttributeSet attrs, int defstyle) {Super (context, Attrs, Defstyle    );        } @Override protected void onmeasure (int widthmeasurespec, int heightmeasurespec) {int width = 0;            for (int i = 0; i < Getchildcount (); i++) {View child = Getchildat (i);            Child.measure (Measurespec.makemeasurespec (0, measurespec.unspecified), Heightmeasurespec);            int w = child.getmeasuredwidth ();        if (w > width) width = w; } Widthmeasurespec = Measurespec.makemeasurespec (width + getpaddingleft () + getpaddingright (), measurespec.exactly)        ; Super.onmeasure (WidthmeaSurespec, Heightmeasurespec); }}

5, the layout of the item: Item_popmenu_more.xml

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/    Android "Android:layout_width=" Wrap_content "android:layout_height=" wrap_content "android:paddingbottom=" 10dip " android:paddingleft= "20dip" android:paddingright= "20dip" android:paddingtop= "10dip" > <imageview an Droid:id= "@+id/menu_icon" android:layout_width= "wrap_content" android:layout_height= "Wrap_content" an        Droid:layout_gravity= "center_vertical" android:layout_marginleft= "5dip" android:layout_marginright= "5dip" android:src= "@mipmap/demand_icon_location"/> <textview android:id= "@+id/menu_text" Android:la        Yout_width= "Wrap_content" android:layout_height= "wrap_content" android:layout_gravity= "center_vertical" Android:singleline= "true" android:textcolor= "#FFFFFF"/></linearlayout>

6, more menu layout: layout_popmenu_more.xml

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/    Android "Android:layout_width=" Match_parent "android:layout_height=" wrap_content "android:orientation=" vertical " android:paddingright= "5dip" > <imageview android:id= "@+id/corner_iv" android:layout_width= "Wrap_c Ontent "android:layout_height=" wrap_content "android:layout_gravity=" right "Android:layout_marginrigh t= "15dip" android:contentdescription= "@null"/> <soban.orderscroll.popmenumorelistview android:id= " @+id/menu_listview "android:layout_width=" wrap_content "android:layout_height=" Wrap_content "Android: Layout_gravity= "Right" android:cachecolorhint= "@android: Color/transparent" android:listselector= "@android: Co Lor/transparent "android:divider=" #FFFFFF "android:dividerheight=" 1px "android:focusable=" true "/> </LinearLayout>

7. Example Activity:mainactivity

public class Mainactivity extends Activity {private static final int user_search = 0;    private static final int user_add = 1;    Private Popmenumore Mmenu;    Private TextView Mtextview;        @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_main);        Initmenu ();        Mtextview = (TextView) Findviewbyid (R.ID.HELLO_TV);                 Mtextview.setonclicklistener (New View.onclicklistener () {@Override public void OnClick (view view) {            Mmenu.showasdropdown (Mtextview);    }        });       private void Initmenu () {mmenu = new Popmenumore (this);       Mmenu.setcorner (r.mipmap.demand_icon_location);        Mmenu.setbackgroundcolor (Color.parsecolor ("#ff8800"));        arraylist<popmenumoreitem> items = new arraylist<> ();        Items.Add (New Popmenumoreitem (User_search, "search")); Items.Add (New Popmenumoreitem (User_adD, "add"));        Items.Add (New Popmenumoreitem (User_search, "search"));        Items.Add (New Popmenumoreitem (User_add, "add"));        Items.Add (New Popmenumoreitem (User_search, "search"));        Items.Add (New Popmenumoreitem (User_add, "add"));        /*items.add (New Popmenumoreitem (User_search, R.mipmap.demand_icon_number, "search"));        Items.Add (New Popmenumoreitem (User_add, R.mipmap.demand_icon_location, "add"));        Items.Add (New Popmenumoreitem (User_search, R.mipmap.demand_icon_number, "search"));        Items.Add (New Popmenumoreitem (User_add, R.mipmap.demand_icon_location, "add"));        Items.Add (New Popmenumoreitem (User_search, R.mipmap.demand_icon_number, "search"));        Items.Add (New Popmenumoreitem (User_add, R.mipmap.demand_icon_location, "add")); */Mmenu.additems (items); Mmenu.setonitemselectedlistener (New Popmenumore.onitemselectedlistener () {@Override public void sel ected (view view, popmenumoreitem item, int position) {switch (iteM.id) {case user_search://startactivity (The new Intent (this, usersearchactivity.cl                        ));                    Break                        Case user_add://StartActivity (New Intent (Getactivity (), useraddactivity.class));                Break    }            }        }); }}

8. Example layout: Activity_main.xml

<?xml version= "1.0" encoding= "Utf-8"? ><relativelayout xmlns:android= "http://schemas.android.com/apk/res/ Android "    xmlns:tools=" Http://schemas.android.com/tools "    android:id=" @+id/activity_main "    android: Layout_width= "Match_parent"    android:layout_height= "match_parent"    android:paddingbottom= "@dimen/ Activity_vertical_margin "    android:paddingleft=" @dimen/activity_horizontal_margin "    android:paddingright = "@dimen/activity_horizontal_margin"    android:paddingtop= "@dimen/activity_vertical_margin" >    < TextView        android:id= "@+id/hello_tv"        android:layout_width= "wrap_content"        android:layout_height= " Wrap_content "        android:text=" Hello world!
