Я попробовал это, и это сработало:
закрытый класс BitmapProvider реализует CurlView.BitmapProvider {
private int[] mBitmapIds = {};
public void setImageList( int[] value )
{
mBitmapIds = value;
}
public BitmapDrawable writeOnDrawable( int drawableId, String text, int x, int y, int width )
{
Bitmap bitmap = BitmapFactory.decodeResource( getResources(), drawableId ).copy( Bitmap.Config.ARGB_8888, true );
Bitmap newBitmap = Bitmap.createBitmap( bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888 );
Canvas canvas = new Canvas( newBitmap );
canvas.drawBitmap( bitmap, new Matrix(), null);
if( text != "" ){
TextView tv = new TextView( getApplicationContext() );
tv.setText( text );
tv.setTextColor( 0xa00050ff );
tv.setTextSize( 24 );
tv.setTypeface( typeface );
Bitmap txtBitmap = Bitmap.createBitmap( width, 768, Bitmap.Config.ARGB_8888 );
Canvas c = new Canvas( txtBitmap );
tv.layout( 0, 0, width, 300 );
tv.draw( c );
canvas.drawBitmap( txtBitmap, x, y, null );
}
return new BitmapDrawable( newBitmap );
}
//@Override
public Bitmap getBitmap( int width, int height, int index )
{
BitmapDrawable drawable;
Page currentPage = getCurrentPage( index );
if( currentPage.getText() != null ){
drawable = writeOnDrawable( mBitmapIds[ index ] , currentPage.getText(), currentPage.getTextFieldX(), currentPage.getTextFieldY(), currentPage.getTextFieldWidth() );
} else {
drawable = writeOnDrawable( mBitmapIds[ index ] , "", currentPage.getTextFieldX(), currentPage.getTextFieldY(), currentPage.getTextFieldWidth() );
}
Bitmap bitmap = drawable.getBitmap();
return bitmap;
}
//@Override
public int getBitmapCount() {
return mBitmapIds.length;
}
}
