Android tall on the Slide menu drawerlayout, solves the problem of not being able to slide full screen

Drawerlayout Preview Drawerlayout The main function is to realize the function of the side-by-side menu effect, and can add some settings to achieve the high effect, then see the dynamic diagram:

Attention to the upper left corner of the icon, there is a lot of wood fun, haha ...

The next step is to introduce how to implement this feature 1. Add dependencies to the build.gradle of the project

    Dependencies {        ... // other code        ' com.android.support:appcompat-v7:24.0.0 '             ' com.android.support:design:24.0.0 ' ...          // other code    }

2. Add toolbar to create the Toolbar.xml file

<?xml version="1.0"encoding="Utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"Xmlns:app="Http://schemas.android.com/apk/res-auto"Android:layout_width="wrap_content"Android:layout_height="wrap_content"> <Android.support.v7.widget.Toolbar Android:id="@+id/toolbar"android:cliptopadding="true"android:fitssystemwindows="true"Android:layout_width="match_parent"Android:layout_height="wrap_content"App:title="News"App:titletextcolor="#fff"> </android.support.v7.widget.Toolbar> </RelativeLayout>

3. Add Drawerlayout to Main.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="match_parent"android:orientation="Vertical"> <!--Add Toolbar--<include layout="@layout/toolbar"/> <!--add Drawerlayout--> <android.support.v4.widget.DrawerLayout Android:id="@+id/drawerlayout"Android:layout_width="match_parent"Android:layout_height="match_parent"> <!--the first-in-one representation of the main content--<framelayout Android:id="@+id/main"Android:layout_width="match_parent"Android:layout_height="match_parent"> </FrameLayout> <!--left side menu (set Layout_gravity to leftmost)--<relativelayout Android:id="@+id/left"Android:layout_width="match_parent"Android:layout_height="match_parent"android:layout_gravity=" Left"> </RelativeLayout> <!--the right-hand menu (set to Layout_gravity)--<relativelayout Android:id="@+id/right"Android:layout_width="match_parent"Android:layout_height="match_parent"android:layout_gravity=" Right"> </RelativeLayout> </android.support.v4.widget.DrawerLayout> </LinearLayout>

Drawerlayout generally divided into three parts main content, left menu, right menu
The content of each section is set by itself, I use the fragment way to set the content, here is only for reference

    // new fragment, details I'm not going to say anything.    New Fragmentmain ();     // add content, relatively simple    Getsupportfragmentmanager (). BeginTransaction (). replace (R.id.main, Fragmentmain). commit ();

So far, the function of the slide-by menu has been initially realized, so look at the effect

Drawerlayout initial effect. gif then, it is to add the effect to the side-slip button 1. To initialize the view before

    Mdrawerlayout = (drawerlayout) Findviewbyid (r.id.drawerlayout);      This . Findviewbyid (R.id.toolbar);    Setsupportactionbar (toolbar);

2. Through actionbardrawertoggle to achieve the effect, the operation is very simple

    New Actionbardrawertoggle (homeactivity.  this,                                         mdrawerlayout,                                         toolbar,                                         R. string . Open,                                          R. string . close);    Mtoggle.syncstate ();    Mdrawerlayout.adddrawerlistener (mtoggle);

So it's over.

Finally, solve the problem that drawerlayout can't slide full screen.

Private voidSetdrawerleftedgesize (activity activity, drawerlayout drawerlayout,floatdisplaywidthpercentage) {    if(Activity = =NULL|| Drawerlayout = =NULL)return; Try {        //Locate Viewdraghelper and set Accessible to TrueField Leftdraggerfield =Drawerlayout.getclass (). Getdeclaredfield ("Mleftdragger");// RightLeftdraggerfield.setaccessible (true); Viewdraghelper Leftdragger= (viewdraghelper) Leftdraggerfield.Get(drawerlayout); //Locate Edgesizefield and set Accessible to TrueField Edgesizefield = Leftdragger.getclass (). Getdeclaredfield ("medgesize"); Edgesizefield.setaccessible (true); intEdgesize =Edgesizefield.getint (Leftdragger); //set a new edge sizePoint displaysize =NewPoint ();        Activity.getwindowmanager (). Getdefaultdisplay (). GetSize (Displaysize); Edgesizefield.setint (Leftdragger, Math.max (Edgesize, (int) (Displaysize.x *( displaywidthpercentage))); } Catch(Nosuchfieldexception e) {}Catch(IllegalArgumentException e) {}Catch(Illegalaccessexception e) {}}

Call this method directly! The last parameter, 1, allows full-screen swipe. If you want the right menu to be full-screen, just change the corresponding "Mleftdragger" to "Mrightdragger".
