Sliding Drawer in Anroid Studio

Introduction

This article explains how to use a SlidingDrawer in your activity. A SlidingDrawer hides the content from the screen and allows the user to bring content onto screen. You can use a sliding drawer vertically or horizontally or both. A SlidingDrawer can only be used inside a RelativeLayout and FrameLayout. In the XML file you will use a SlidingDrawer with one button to handle the layout and an imageview that you want to drag.

In a Java class file you will set the SlidingDrawer on setOnDarwablwCloseListener that closes the sliding drawer when you will click on the handle button. Inside the onDrawableClose you will set the handle button on the setBackgroundResource that sets the background resource on button click. After this, to open the sliding drawer you will set the SlidingDawer on setDawableOpenListener that opens the drawer when you will click on the handle button.

Step 1

Create an XML file and write this:

<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:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    android:paddingBottom="@dimen/activity_vertical_margin"

    tools:context=".MainActivity"

        android:background="#d1e7df">

 

 

    <SlidingDrawer

            android:layout_width="fill_parent"

            android:layout_height="fill_parent"

            android:content="@+id/content"

            android:handle="@+id/handle" android:id="@+id/slidingDrawer"

            android:layout_centerVertical="true"

            android:layout_centerHorizontal="true">

 

        <Button

                android:id="@+id/handle"

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

 

                android:background="@drawable/up"/>

 

        <LinearLayout

                android:id="@+id/content"

                android:layout_width="fill_parent"

                android:layout_height="fill_parent"

                android:orientation="vertical">

 

          <ImageView

                  android:layout_height="fill_parent"

                  android:layout_width="fill_parent"

                  android:background="@drawable/img"

                 >

          </ImageView>

        </LinearLayout>

    </SlidingDrawer> 

</RelativeLayout>


Step 2

Create a Java class file and write this:
 

package com.slidingdrawerexample; 

import android.app.Activity;

import android.os.Bundle;

import android.widget.Button;

import android.widget.SlidingDrawer;

 

public class MainActivity extends Activity {

 

  SlidingDrawer sliding;

    Button button;

 

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

 

        sliding=(SlidingDrawer)findViewById(R.id.slidingDrawer);

        button=(Button)findViewById(R.id.handle);

 

        sliding.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener() {

            @Override

            public void onDrawerClosed() {

                button.setBackgroundResource(R.drawable.down);

            }

        });

 

    sliding.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener() {

        @Override

        public void onDrawerOpened() {

            button.setBackgroundResource(R.drawable.up);

        }

    });

    }

 }
 

Step 3

Android Menifest file

 

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.slidingdrawerexample"

    android:versionCode="1"

    android:versionName="1.0" >

 

    <uses-sdk

        android:minSdkVersion="7"

        android:targetSdkVersion="17" />

 

    <application

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name="com.slidingdrawerexample.MainActivity"

            android:label="@string/app_name" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

 

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

 

</manifest>
