public class views {

    @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR1)
    public TextView titulox(Context context, String texto)
    {



        TextView titulo;

        titulo = new TextView(context);
        titulo.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
        titulo.setText(texto);
        titulo.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
        titulo.setTextSize(36);
        titulo.setVisibility(View.VISIBLE);



        return titulo;
    }

    public ImageView imagen (String src, Context context) throws IOException {

        Bitmap bitmap = null;

        try {
            java.net.URL url = new java.net.URL(src);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.connect();
            InputStream inputStream = connection.getInputStream();
            bitmap = BitmapFactory.decodeStream(inputStream);
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }

        ImageView imagen = new ImageView(context);
        imagen.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 350));
        imagen.setImageBitmap(bitmap);
        imagen.setScaleType(ImageView.ScaleType.CENTER_CROP);
        return imagen;
    }


    @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR1)
    public TextView desarrollo(Context context, String texto)
    {


        TextView desarrollo;

        desarrollo = new TextView(context);
        desarrollo.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
        desarrollo.setText(texto);
        desarrollo.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
        desarrollo.setTextSize(14);
        desarrollo.setVisibility(View.VISIBLE);




        return desarrollo;
    }

}

重用意见 - 如何？
