I have to make a listview from database and i want to put a image that is clickable in my list.I use CursorAdapter for it,but my image does not show on my list.Here is my BooksCursorAdapter
public class BooksCursorAdapter extends CursorAdapter {
public BooksCursorAdapter(Context context, Cursor c) {
super(context, c, 0 );
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return LayoutInflater.from(context).inflate(R.layout.books_list_item, parent, false);
}
@Override
public void bindView(View view,final Context context, Cursor cursor) {
TextView productText = view.findViewById(R.id.productText);
TextView priceText = view.findViewById(R.id.priceText);
TextView quantityText = view.findViewById(R.id.quantityText);
ImageView shopButton = view.findViewById(R.id.shop_button);
int productColumnIndex = cursor.getColumnIndex(BooksContract.BooksEntry.COLUMN_BOOKS_PRODUCT);
int priceColumnIndex = cursor.getColumnIndex(BooksContract.BooksEntry.COLUMN_BOOKS_PRICE);
final int quantityColumnIndex = cursor.getColumnIndex(BooksContract.BooksEntry.COLUMN_BOOKS_QUANTITY);
String bookProduct = cursor.getString(productColumnIndex);
String bookPrice = cursor.getString(priceColumnIndex);
final int bookQuantity = cursor.getInt(quantityColumnIndex);
productText.setText(bookProduct);
priceText.setText(bookPrice);
quantityText.setText(Integer.toString(bookQuantity));
int idColumnIndex = cursor.getColumnIndex(BooksContract.BooksEntry._ID);
final int booksId = cursor.getInt(idColumnIndex);
shopButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Uri currentUri = ContentUris.withAppendedId(BooksContract.BooksEntry.CONTENT_URI, booksId);
makeSale(context, bookQuantity, currentUri);
}
});
}
private void makeSale(Context context, int bookQuantity, Uri uri) {
if (bookQuantity == 0) {
Toast.makeText(context, R.string.no_books, Toast.LENGTH_SHORT).show();
} else {
int newQuantity = bookQuantity - 1;
ContentValues values = new ContentValues();
values.put(BooksContract.BooksEntry.COLUMN_BOOKS_QUANTITY, newQuantity);
context.getContentResolver().update(uri, values, null, null);
}
}
}
Everything works fine and how it should be only that my image is not showing.
My book_list_item.xml:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="horizontal">
<LinearLayout
android:layout_width="333dp"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="@dimen/activity_margin">
<TextView
android:id="@+id/productText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif-medium"
android:textAppearance="?android:textAppearanceMedium"
android:textColor="#2B3D4D" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="@+id/priceText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif"
android:textAppearance="?android:textAppearanceSmall"
android:textColor="#AEB6BD"
android:padding="5dp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/currencyTextList" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/quantityTextList"
android:padding="5dp"/>
<TextView
android:id="@+id/quantityText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif"
android:textAppearance="?android:textAppearanceSmall"
android:textColor="#AEB6BD" />
</LinearLayout>
</LinearLayout>
<ImageView
android:layout_width="52dp"
android:layout_height="match_parent"
android:src="@drawable/shop_button"
android:id="@+id/shop_button"/>
</LinearLayout>
The image appears in my preview but not on my phone.I want to display an image stored on xml, that I can click on.
