How to pass bitmap between activities in Android

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>
