Change view onClick coverflow - Android

Question

I'm using this CoverFlow : http://www.inter-fuser.com/2010/02/android-coverflow-widget-v2.html

I want to be able to change View when I click on a button, the button being a back/forward icon which will take you to the previous/next item in the coverflow.

I have modded the coverflow slightly so that I use an XML layout instead.

Here is my onCreate() method:

 setContentView(R.layout.main);

 CoverFlow coverFlow = (CoverFlow)findViewById(R.id.coverflow);  

 coverFlow.setAdapter(new ImageAdapter(this));
 ImageAdapter coverImageAdapter =  new ImageAdapter(this);     
 coverFlow.setAdapter(coverImageAdapter);
 coverFlow.setSpacing(-20);
 coverFlow.setSelection(0, true);
 coverFlow.setAnimationDuration(1000);

 tv = (TextView)findViewById(R.id.textView1);

 coverFlow.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        Toast.makeText(getBaseContext(), String.valueOf(arg2), Toast.LENGTH_SHORT).show();
    }
 });

 coverFlow.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        tv.setText(String.valueOf(arg2));
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // Do something
    }
 });

My XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

    android:orientation="vertical" >

    <com.demo.app.coverflow.CoverFlow

        android:layout_height="fill_parent" />

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:layout_alignParentLeft="true"
        android:layout_marginBottom="39dp"
        android:layout_marginLeft="35dp"
        android:background="@drawable/button_left" />

    <Button
        android:id="@+id/button2"

        android:layout_alignParentRight="true"
        android:layout_marginBottom="39dp"
        android:layout_marginRight="35dp"
        android:background="@drawable/button_right" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="55dp"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:text="hello"
        android:textColor="@color/White"
        android:textSize="16dp" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"

        android:layout_marginRight="170dp"
        android:layout_marginTop="15dp"
        android:src="@drawable/unsa_logo" />

    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_marginRight="14dp"
        android:layout_marginTop="23dp"
        android:src="@drawable/pnc_logo" />

</RelativeLayout>

Answer 1

While I was trying to find out how to add the animation I came across this which does everything in just one line :

go left

coverFlow.onKeyDown(KeyEvent.KEYCODE_DPAD_LEFT, new KeyEvent(0, 0));

go right

coverFlow.onKeyDown(KeyEvent.KEYCODE_DPAD_RIGHT, new KeyEvent(0, 0));

(just add each line to their respective button onclick methods

Hope this can help anyone else who finds them self in the same situation as I was :)
