How to pass an image from one activity another activity in Android

This example demonstrates how to do I pass an image from one Activity in android.

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"?>

<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:padding="16dp"

   tools:context=".MainActivity">

   <Button

      android:id="@+id/btnSend"

      android:layout_width="match_parent"

      android:layout_height="wrap_content"

      android:layout_marginTop="40dp"

      android:onClick="SendImage"

      android:text="Send Image" />

   <ImageView

      android:id="@+id/imageView"

      android:layout_width="match_parent"

      android:layout_height="match_parent"

      android:layout_below="@id/btnSend"

      android:layout_marginTop="10dp"

      android:src="@drawable/image" />

</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.java

public class MainActivity extends AppCompatActivity {

   @Override

   protected void onCreate(Bundle savedInstanceState) {

      super.onCreate(savedInstanceState);

      setContentView(R.layout.activity_main);

   }

   public void SendImage(View view) {

      Intent intent = new Intent(MainActivity.this, SecondActivity.class);

      intent.putExtra("resId", R.drawable.image);

      startActivity(intent);

   }

}

Step 4 − Create an empty activity and add the following code:

Activity_second.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:layout_width="match_parent"

   android:layout_height="match_parent"

   android:padding="8dp"

   tools:context=".SecondActivity">

   <TextView

      android:id="@+id/textView"

      android:layout_width="wrap_content"

      android:layout_height="wrap_content"

      android:layout_centerHorizontal="true"

      android:layout_marginTop="40dp"

      android:text="Second Activity"

      android:textSize="24sp"

      android:textStyle="bold"/>

   <ImageView

      android:layout_width="match_parent"

      android:layout_height="match_parent"

      android:layout_below="@id/textView"

      android:layout_marginTop="5dp"

      android:id="@+id/imageView2"/>

</RelativeLayout>

SecondActivity.java

public class SecondActivity extends AppCompatActivity {

   ImageView imageView;

   @Override

   protected void onCreate(Bundle savedInstanceState) {

      super.onCreate(savedInstanceState);

      setContentView(R.layout.activity_second);

      imageView = findViewById(R.id.imageView2);

      Bundle bundle = getIntent().getExtras();

      if (bundle != null) {

         int resId = bundle.getInt("resId");

         imageView.setImageResource(resId);

      }

   }

}

Step 5 − 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.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=".SecondActivity"></activity>

      <activity android:name=".MainActivity">

         <intent-filter>

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

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

         </intent-filter>

      </activity>

   </application>

</manifest>
