How to pass bitmap between activities

A bitmap created from R.drawable.icon will be passed from one activity (AndroidPassingBitmap) to another activity (AndroidReceiveBitmap).



Modify the activity AndroidPassingBitmap.java, simple create a bitmap and pass to the second activity.
/AndroidPassingBitmap/src/com/AndroidPassingBitmap/AndroidPassingBitmap.java

package com.AndroidPassingBitmap;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;

public class AndroidPassingBitmap extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.icon);
        
        Intent intent = new Intent();
        intent.setClass(AndroidPassingBitmap.this, AndroidReceiveBitmap.class);
        intent.putExtra("Bitmap", bitmap);
        startActivity(intent);

    }
}

Create a new activity to retrieve and display the bitmap.
/workspace/AndroidPassingBitmap/src/com/AndroidPassingBitmap/AndroidReceiveBitmap.java

package com.AndroidPassingBitmap;

import android.app.Activity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.widget.ImageView;

public class AndroidReceiveBitmap extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  
  Bitmap bitmap = (Bitmap)this.getIntent().getParcelableExtra("Bitmap");
  
  setContentView(R.layout.newimage);
  ImageView viewBitmap = (ImageView)findViewById(R.id.bitmapview);
  
  viewBitmap.setImageBitmap(bitmap);
  
 }

}

Create the layout of the second activity.
/workspace/AndroidPassingBitmap/res/layout/newimage.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<ImageView  
    android:id="@+id/bitmapview"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    />
</LinearLayout>

Update AndroidManifest.xml to include the second activity in the package.
/workspace/AndroidPassingBitmap/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.AndroidPassingBitmap"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".AndroidPassingBitmap"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".AndroidReceiveBitmap"
                  android:label="AndroidReceiveBitmap">
        </activity>
    </application>
    <uses-sdk android:minSdkVersion="4" />

</manifest>
