STEP 2: Preparing the multimedia components.

This project is to introduce multimedia elements such as images and sound. I have prepared the files, it’s available for download here. Inside the zip files you will have the image for background and a picture of an object. The other material is the sound.

imageFigure 4: Inside the mmmaterials.zip (download here)

Put the image files in the res/drawable, and the sound in the assets (as in Figure 5). Use the file explorer to locate the workspace. (Workspace – is a folder assigned as the project storage for Eclipse, to locate go to Project –> Properties, you’ll se Location in the Resources)

STEP 3: The GUI design for the app.

Or simple copy and paste the main.xml code in the XML mode.

imageFigure 8: The Graphical Layout designer in XML mode.

main.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"
android:background="@drawable/bd">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:keepScreenOn="true" android:text="Kereta lumba"/>
<ImageView android:layout_height="wrap_content" android:src="@drawable/kereta" android:id="@+id/imageView1" android:layout_width="match_parent"></ImageView>
<Button android:layout_height="wrap_content" android:layout_width="match_parent" android:text="Sebutan: kereta lumba" android:id="@+id/btnsebutan"></Button>
<MediaController android:id="@+id/mediaController1" android:layout_width="wrap_content" android:layout_height="wrap_content"></MediaController>
</LinearLayout>


 


STEP 4: The sourcecode.


Locate the Java source code file in the src. Copy the Java source to your source file. Make sure to change the package name.


imageFigure 9: The Java sourcecode.


Java source:


package YOUR_PACKAGE_NAME_HERE;

import android.app.Activity;
import android.content.res.AssetFileDescriptor;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MMTEST1 extends Activity implements OnClickListener{

private MediaPlayer mp;
private Button btnsebutan;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

//
btnsebutan = (Button) findViewById(R.id.btnsebutan);
btnsebutan.setEnabled(true);// disable button
btnsebutan.setOnClickListener(this);


}
public void onClick(View v) {

mp = new MediaPlayer();
try
{
AssetFileDescriptor afd = getAssets().openFd("keretalumba.mp3");
mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
mp.prepare();
mp.start();
}
catch(Exception e) {}
}
}

STEP 5: Compile and running.

    1. Right click on ur project Name (on the Project Navigator) and choose New->Other from the list. Hit on Android folder and you'll see Android XML Layout File and hit Next button. Enter the file name (eg: pref.xml), choose LinearLayout from Root Element, and Finish button.
      All the best...

ViewFlipper Example–a simple FlashCard

UPDATE: Improved with Fling gesture (Sept 2012) UPDATE: ViewFlipper with Flip-In and Flip-Out Animation (August 2012) This tutorial is to demonstrate the ViewFlipper layout that is almost similar to CardLayout (in Java). The app will produce a simple Flash card that provide several screens with different picture for each card. Flip-in and Flip-out animation provided. Added in Sept 2012 – an improvement to support Fling gesture – enjoy… The amendment is only on the coding part. Some how the layout design (main.xml) is quite long. Later I’ll produce separated screen by including several XML layout from outside files. Screenshots;
