Add description to Android Gallery - (Pictures and text)

Question

Hi to all!

I'm working on my new project but I can't figure out how to add a text under my Gallery.

I have 3 pictures, if I slide on picture 2 I can see under picture 1 and 3 the correct description but it doesn't appear the description under the selected picture (in this case the number 2).

This is my code:

public void onClick(View v, int scelta){ //in base all'intero della scelta ho una voce del menu :) if(scelta == 1){ Intent i = new Intent(this, Parco.class); startActivity(i); }else if(scelta == 2 ){ Intent j = new Intent(this, Servizi.class); startActivity(j); } else { this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?f=d&saddr=37.4,-121.9&daddr=Bellevue, WA&hl=en"))); } }

public class ImageAdapter extends BaseAdapter {

private Context ctx; private int itemBackground;

public ImageAdapter(Context c) {

ctx = c;

//Style TypedArray a = obtainStyledAttributes(R.styleable.Gallery01); itemBackground = a.getResourceId(R.styleable.Gallery01_android_galleryItemBackground, 0); a.recycle();
}

@Override public int getCount() { return pics.length; }

@Override public Object getItem(int arg0) { return arg0; }

@Override public long getItemId(int arg0) { return arg0; }

@Override public View getView(int elemento, View arg1, ViewGroup arg2) {

        LinearLayout layout = new LinearLayout(getApplicationContext());            
        layout.setOrientation(LinearLayout.VERTICAL);

        ImageView img = null;

// Riutilizziamo l'eventuale convertView. if (arg1 == null) { img = new ImageView(ctx); } else { img = (ImageView) arg1; }

        img.setImageResource(pics[elemento]);
        img.setScaleType(ImageView.ScaleType.FIT_XY);
        img.setLayoutParams(new Gallery.LayoutParams(280,210));
        img.setBackgroundResource(itemBackground);

        TextView tv = new TextView(ctx);

        String titolo = "";

        if(elemento == 0){
         titolo = "le Grotte";
        } else if (elemento == 1) {
         titolo = "il Parco";
        } else if (elemento == 2) {
         titolo = "i Servizi";
        }

        tv.setText(titolo);
        tv.setGravity(Gravity.CENTER);            

  //Utilizzo l'AssetManager per cambiare il font
  AssetManager assetManager = getResources().getAssets();
  Typeface typeface = Typeface.createFromAsset(assetManager, "fonts/CALIFR.TTF");
        tv.setTypeface(typeface);
        tv.setTextSize(50);
        tv.setPadding(0,0,0,40); //imposto il margine di bottom del testo

        layout.addView(img);
        layout.addView(tv);

        return layout;

}

}

@Override public View makeView() {

ImageView iView = new ImageView(this); iView.setScaleType(ImageView.ScaleType.FIT_CENTER); iView.setLayoutParams(new ImageSwitcher.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT)); iView.setBackgroundColor(0xFF000000);

return iView; }

}

Thank you!!! Marco

Answer 1

The TextView class has attributes to place a Drawable above, below, etc

Answer 2

tv.setTextColor(0xffffffff);
