This example demonstrate about How to resize Image in Android App.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<? xml version= "1.0" encoding= "utf-8" ?>
<android.support.v4.widget.DrawerLayout
   xmlns: android = "http://schemas.android.com/apk/res/android"
   xmlns: app = "http://schemas.android.com/apk/res-auto"
   xmlns: tools = "http://schemas.android.com/tools"
   android :id= "@+id/drawer_layout"
   android :layout_width= "match_parent"
   android :layout_height= "match_parent"
   android :fitsSystemWindows= "true"
   tools :openDrawer= "start" >
   <include
      layout= "@layout/app_bar_main"
      android :layout_width= "match_parent"
      android :layout_height= "match_parent" />
   <android.support.design.widget.NavigationView
      android :id= "@+id/nav_view"
      android :layout_width= "wrap_content"
      android :layout_height= "match_parent"
      android :layout_gravity= "start"
      android :fitsSystemWindows= "true"
      app :headerLayout= "@layout/nav_header_main"
      app :menu= "@menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>

Step 3 − Add the following code to res/layout/nav_header_main.xml.

<? xml version= "1.0" encoding= "utf-8" ?>
<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android"
   xmlns: app = "http://schemas.android.com/apk/res-auto"
   android :layout_width= "match_parent"
   android :layout_height= "@dimen/nav_header_height"
   android :background= "@drawable/side_nav_bar"
   android :gravity= "bottom"
   android :orientation= "vertical"
   android :paddingLeft= "@dimen/activity_horizontal_margin"
   android :paddingTop= "@dimen/activity_vertical_margin"
   android :paddingRight= "@dimen/activity_horizontal_margin"
   android :paddingBottom= "@dimen/activity_vertical_margin"
   android :theme= "@style/ThemeOverlay.AppCompat.Dark" >
   <ImageView
      android :id= "@+id/imageView"
      android :layout_width= "wrap_content"
      android :layout_height= "wrap_content"
      android :contentDescription= "@string/nav_header_desc"
      android :paddingTop= "@dimen/nav_header_vertical_spacing"
      app :srcCompat= "@mipmap/ic_launcher_round" />
   <TextView
      android :layout_width= "match_parent"
      android :layout_height= "wrap_content"
      android :paddingTop= "@dimen/nav_header_vertical_spacing"
      android :text= "@string/nav_header_title"
      android :textAppearance= "@style/TextAppearance.AppCompat.Body1" />
   <TextView
      android :id= "@+id/textView"
      android :layout_width= "wrap_content"
      android :layout_height= "wrap_content"
      android :text= "@string/nav_header_subtitle" />
</LinearLayout>

Step 4 − Add the following code to res/layout/app_bar_main.xml.

<? xml version= "1.0" encoding= "utf-8" ?>
<android.support.design.widget.CoordinatorLayout
   xmlns: android = "http://schemas.android.com/apk/res/android"
   xmlns: app = "http://schemas.android.com/apk/res-auto"
   xmlns: tools = "http://schemas.android.com/tools"
   android :layout_width= "match_parent"
   android :layout_height= "match_parent"
   tools :context= ".MainActivity" >
   <android.support.design.widget.AppBarLayout
      android :layout_width= "match_parent"
      android :layout_height= "wrap_content"
      android :theme= "@style/AppTheme.AppBarOverlay" >
   <android.support.v7.widget.Toolbar
      android :id= "@+id/toolbar"
      android :layout_width= "match_parent"
      android :layout_height= "?attr/actionBarSize"
      android :background= "?attr/colorPrimary"
      app :popupTheme= "@style/AppTheme.PopupOverlay" />
   </android.support.design.widget.AppBarLayout>
   <include layout= "@layout/content_main" />
   <android.support.design.widget.FloatingActionButton
      android :id= "@+id/fab"
      android :layout_width= "wrap_content"
      android :layout_height= "wrap_content"
      android :layout_gravity= "bottom|end"
      android :layout_margin= "@dimen/fab_margin"
      app :srcCompat= "@android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>

Step 5 − Add the following code to res/layout/content_main.xml.

<? xml version= "1.0" encoding= "utf-8" ?>
<android.support.constraint.ConstraintLayout
   xmlns: android = "http://schemas.android.com/apk/res/android"
   xmlns: app = "http://schemas.android.com/apk/res-auto"
   xmlns: tools = "http://schemas.android.com/tools"
   android :layout_width= "match_parent"
   android :layout_height= "match_parent"
   app :layout_behavior= "@string/appbar_scrolling_view_behavior"
   tools :context= ".MainActivity"
   tools :showIn= "@layout/app_bar_main" >
</android.support.constraint.ConstraintLayout>

Step 6 − Add the following code to res/menu/activity_main_drawer.xml.

<? xml version= "1.0" encoding= "utf-8" ?>
<menu xmlns: android = "http://schemas.android.com/apk/res/android"
   xmlns: tools = "http://schemas.android.com/tools"
   tools :showIn= "navigation_view" >
   <group android :checkableBehavior= "single" >
      <item
         android :id= "@+id/nav_camera"
         android :icon= "@drawable/ic_menu_camera"
         android :title= "Import" />
      <item
         android :id= "@+id/nav_gallery"
         android :icon= "@drawable/ic_menu_gallery"
         android :title= "Gallery" />
      <item
         android :id= "@+id/nav_slideshow"
         android :icon= "@drawable/ic_menu_slideshow"
         android :title= "Slideshow" />
      <item
         android :id= "@+id/nav_manage"
         android :icon= "@drawable/ic_menu_manage"
         android :title= "Tools" />
   </group>
   <item android :title= "Communicate" >
      <menu>
         <item
            android :id= "@+id/nav_share"
            android :icon= "@drawable/ic_menu_share"
            android :title= "Share" />
         <item
            android :id= "@+id/nav_send"
            android :icon= "@drawable/ic_menu_send"
            android :title= "Send" />
      </menu>
   </item>
</menu>

Step 7 − Add the following code to src/MainActivity.java

package app.tutorialspoint.com.sample ;
import android.os.Bundle ;
import android.support.annotation. NonNull ;
import android.support.design.widget.FloatingActionButton ;
import android.support.design.widget.Snackbar ;
import android.view.View ;
import android.support.design.widget.NavigationView ;
import android.support.v4.view.GravityCompat ;
import android.support.v4.widget.DrawerLayout ;
import android.support.v7.app.ActionBarDrawerToggle ;
import android.support.v7.app.AppCompatActivity ;
import android.support.v7.widget.Toolbar ;
import android.view.Menu ;
import android.view.MenuItem ;
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
   @Override
   protected void onCreate (Bundle savedInstanceState) {
      super .onCreate(savedInstanceState) ;
      setContentView(R.layout. activity_main ) ;
      Toolbar toolbar = findViewById(R.id. toolbar ) ;
      setSupportActionBar(toolbar) ;
      FloatingActionButton fab = findViewById(R.id. fab ) ;
      fab.setOnClickListener( new View.OnClickListener() {
         @Override
         public void onClick (View view) {
            Snackbar. make (view , "Replace with your own action" ,
            Snackbar. LENGTH_LONG )
            .setAction( "Action" , null ).show() ;
         }
      }) ;
      DrawerLayout drawer = findViewById(R.id. drawer_layout ) ;
      ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
      this, drawer , toolbar , R.string. navigation_drawer_open ,
      R.string. navigation_drawer_close ) ;
      drawer.addDrawerListener(toggle) ;
      toggle.syncState() ;
      NavigationView navigationView = findViewById(R.id. nav_view ) ;
      navigationView.setNavigationItemSelectedListener( this ) ;
   }
   @Override
   public void onBackPressed () {
      DrawerLayout drawer = findViewById(R.id. drawer_layout ) ;
      if (drawer.isDrawerOpen(GravityCompat. START )) {
         drawer.closeDrawer(GravityCompat. START ) ;
      } else {
         super .onBackPressed() ;
      }
   }
   @Override
   public boolean onCreateOptionsMenu (Menu menu) {
      // Inflate the menu; this adds items to the action bar if it is present.
      getMenuInflater().inflate(R.menu. main , menu) ;
      return true;
   }
   @Override
   public boolean onOptionsItemSelected (MenuItem item) {
      int id = item.getItemId() ;
      if (id == R.id. action_settings ) {
         return true;
      }
      return super .onOptionsItemSelected(item) ;
   }
   @SuppressWarnings ( "StatementWithEmptyBody" )
   @Override
   public boolean onNavigationItemSelected ( @NonNull MenuItem item) {
      // Handle navigation view item clicks here.
      int id = item.getItemId() ;
      if (id == R.id. nav_camera ) {
         // Handle the camera action
      } else if (id == R.id. nav_gallery ) {
      } else if (id == R.id. nav_slideshow ) {
         } else if (id == R.id. nav_manage ) {
         } else if (id == R.id. nav_share ) {
         } else if (id == R.id. nav_send ) {
      }
      DrawerLayout drawer = findViewById(R.id. drawer_layout ) ;
      drawer.closeDrawer(GravityCompat. START ) ;
      return true;
   }
}

Step 8 − Add the following code to androidManifest.xml

<? xml version= "1.0" encoding= "utf-8" ?>
<manifest xmlns: android = "http://schemas.android.com/apk/res/android"
   package= "app.tutorialspoint.com.sample" >
   <application
      android :allowBackup= "true"
      android :icon= "@mipmap/ic_launcher"
      android :label= "@string/app_name"
      android :roundIcon= "@mipmap/ic_launcher_round"
      android :supportsRtl= "true"
      android :theme= "@style/AppTheme" >
      <activity
         android :name= ".MainActivity"
         android :theme= "@style/AppTheme.NoActionBar" >
         <intent-filter>
            <action android :name= "android.intent.action.MAIN" />
            <category android :name= "android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –
