Question

How to create a shelf like view in android that show several book in any row? Also, it should have horizontal and vertical features like the moon+reader app has.

I can write a shelf view that moves horizontally but it doesn’t fully work. I used a xml file for view items that included image, text and button. I wrote a class that extends AdapterView to create a customized ListView that I called "shelf view". Unfortunately, my program show one row and I can’t use it for several row.

Last Updated: Now, I can detect a new way for create shelf-view better than the previous solution. I described it in CodeProject

By the Way, In this application I used two classes:

• HorizontalListView Class that extends the AdapterView. It downloaded from GitHub

• Quaere library use almost same as Linq2Object in .Net. You can download here.

There are some ways to implement shelf view that it have two features(horizontal & vertical scroll). I try to write a program that can run dynamically. This sample App have a XML file and a showShelfView java class.

So you can see my App:

main XML file: First, Add following code in main.XML

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/sclView">
    <TableLayout
            android:id="@+id/tblLayout"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" 
           android:padding="0dp">
    </TableLayout>
</ScrollView>

showShelfView Class: Inner TableLayout add several HorizontalScroll equals with number of rows. Also inner any TableRow add Image.

Don’t forget set a shelf image for Row’s background:

public class showShelfView extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);


        int numRow = 4;
        int numCol = 8;

        TableLayout tblLayout = (TableLayout) findViewById(R.id.tblLayout);

        for(int i = 0; i < numRow; i++) {
            HorizontalScrollView HSV = new HorizontalScrollView(this);
            HSV.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));

            TableRow tblRow = new TableRow(this);
            tblRow.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
            tblRow.setBackgroundResource(R.drawable.bookshelf);

            for(int j = 0; j < numCol; j++) {
            ImageView imageView = new ImageView(this);
                imageView.setImageResource(R.drawable.book1);

                TextView textView = new TextView(this);
                textView.setText("Java Tester");
                textView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

                tblRow.addView(imageView,j);
            }

            HSV.addView(tblRow);
            tblLayout.addView(HSV, i);
        }
    }

}
