Open Source project Slidingmenu

We're going to use an open source project Slidingmenu

is the slide menu

Go to GitHub and search for slidingmenu .

Collect More 9000 , share More

It's awesome.

Thousands of of them are awesome.

we'll download it.

If we're going to put this open source project in our own project,

then import the Module

We checked slidingmenu-master 's library .

After import, of course, will be error

We open slidingmenu 's gradle .

Modify Gradle According to the error prompt

dependencies {

Classpath ' com.android.tools.build:gradle:2.1.0 '

}

dependencies {

Compile ' com.android.support:support-v4:23.3.0 '

}

Android {

Compilesdkversion 23

Buildtoolsversion "23.0.3"

Defaultconfig {

Minsdkversion 7

Targetsdkversion 16

}

There was a mistake after the modification .

The sin method is wrong , Let's go in and see.

We found this method

float distanceinfluenceforsnapduration (float f) {

F-= 0.5f; Center the values about 0.

F *= 0.3f * math.pi/2.0f;

return (float) floatmath.sin (f);

}

Why does the sin method here have an error?

Because Floatmath is out of date , its sin method does not exist.

So we took the Float off

into Math.sin (f);

Get

and then we have to rely on this slidingmenu library .

Open Dependencies for project Structure

Add Module Dependency

Select Library_slidingmenu

Now let's use the slidingmenu Slide menu .

We go to our own project to use the slide menu Activity

like I got mainactivity inside.

We'll first change the mainactivity 's parent appcompatactivity to silidingmenu . slidingfragmentactivity

public class Mainactivity extends Slidingfragmentactivity {

}

here onCreate method of permission protected error

Because the slidingfragmentactivity is supposed to be onCreate and sealed.

So let's change the permission modifier.

@Override

public void OnCreate (Bundle savedinstancestate) {

Super.oncreate (savedinstancestate);

Setcontentview (R.layout.activity_main);

}

and then we started setting up slidingmenu .

write a layout and then set the slide-by menu layout

Setbehindcontentview (R.layout.activity_main_menu);

get slidingmenu

Mslidingmenu = Getslidingmenu ();

set slidingmenu on the left

Mslidingmenu.setmode (Slidingmenu.left);

set how the slidingmenu is pulled out , fullscreen is all can pull out , MARGIN Just pull it out on the edge.

Mslidingmenu.settouchmodeabove (Slidingmenu.touchmode_none);

here is How much of the following main is left after the move out, my resolution is 320*480, I give a , put in Dimen.xml inside

put in the dimen.xml inside the words can be adapted to the screen , do not have to convert to convert .

Mslidingmenu.setbehindoffsetres (R.dimen.activity_main_behind_width);

basic Setup is complete.

But there's a little bit of a problem, that is, if we have the same activity background on both sides ,

Then it's hard to tell where is main, where is the menu

So we put a shadow on the edge of the menu ,

To differentiate two parts

How to do it

We write a custom pattern in drawable shadow.xml

Here's my obsessive-compulsive disorder .

If you don't want to see it, just skip it.

We're going to have a gradient color.

We have a total of 123456789abcdef in the system .

If you choose 1 and F, the middle is 8, the left side is 234567, and the right side is 9ABCDE,

If you choose 2 and E, the middle is 8, the left side is 34567, and the right side is 9ABCD. , outside is 1 and F

If you choose 3 and D, then the middle is 8, the left side is 4567, the right side is 9abc, the outside is 12 and EF

If you choose 4 and C, then the middle is 8, the left side is 567, the right side is 9ab, It's 123 and def out there.

That's it , perfect , Obsessive-Compulsive disorder .

<shape xmlns:android= "Http://schemas.android.com/apk/res/android" >

<gradient

Android:endcolor= "#444444"

Android:centercolor= "#88888"

Android:startcolor= "#cccccc"

/>

</shape>

and then we'll set it up for Mslidingmenu .

set the drawable of Shadow

Mslidingmenu.setshadowdrawable (R.drawable.shadow);

set The width of the shadow and see for yourself

Mslidingmenu.setshadowwidthres (R.dimen.activity_main_shadow_width);

Okay, now our slidingmenu is done. If you want something, just go to the layout and write it.

Exhale is toggle ();
