Working with Camera in Android

Taking a Picture in Android

Create a new project in Eclipse from File ⇒ New ⇒ Android ⇒ Application Project and fill all the required information. I left my main activity as MainActivity.java

Working with camera needs set of permissions and features in the AndroidManifest.xml file. Add following in your AndroidManifest.xml

android.hardware.camera – Required to use camera hardware

Adding required permissions in manifest file

Open your layout file of your main activity activity_main.xml and paste the following code.
Here layout consists of a button and imageview.

<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"

    tools:context=".MainActivity" >

    <Button

        android:id="@+id/button1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentTop="true"

        android:layout_centerHorizontal="true"

        android:layout_marginTop="24dp"

        android:text="@string/take_pic" />

    <ImageView

        android:id="@+id/imageView1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_below="@+id/button1"

        android:layout_centerHorizontal="true"

        android:layout_marginTop="115dp"

        android:contentDescription="@string/TODO"

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

</RelativeLayout>

Go to mainactivity java class and copy the following codes:

public class MainActivity extends Activity {

Button b;

ImageView iv;

Bitmap bm;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

iv = (ImageView) findViewById(R.id.imageView1);

Button b = (Button) findViewById(R.id.button1);

b.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View arg0) {

Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

startActivityForResult(i, 0);

}

});

}

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

super.onActivityResult(requestCode, resultCode, data);

Bitmap bitmap = (Bitmap) data.getExtras().get("data");

iv.setImageBitmap(bitmap);

}

Now the project is ready to run.
