问题描述

我想哪里有A，B，C，D，E ....改变一个大胆的风格字母和更改背景。
是一种可能性，因为我试图（注释行），但总有一些事情是行不通的。

 公共查看getView（INT位置，查看convertView，父母的ViewGroup）{    LayoutInflater吹气=（LayoutInflater）上下文

解决方案

  Spannable wordtoSpan =新SpannableString（A）;wordtoSpan.setSpan（新ForegroundColorSpan（Color.BLUE），15，30，Spannable.SPAN_EXCLUSIVE_EXCLUSIVE）;textView.setText（wordtoSpan）;
 

I would like to where there is A, B, C, D, E .... change the style letters on a bold and change the background. is a possibility because I was trying to (commented out lines), but always something is not working.

public View getView(int position, View convertView, ViewGroup parent) {

    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View gridView;

    if (convertView == null) {

        gridView = new View(context);

        // get layout from mobile.xml
        gridView = inflater.inflate(R.layout.mobile, null);

        int y = position / 11;
        int x = position % 11;

        //if(x<x+11 || x> plansza.length || y<0 || y> plansza[x].length);

        // set value into textview
        TextView textView = (TextView) gridView
                .findViewById(R.id.grid_item_label);

        textView.setText((x > 0 && y > 0) ? plansza[x-1][y-1].toString().substring(0,1): mobileValues[position]);

        // set image based on selected text
        ImageView imageView = (ImageView) gridView
                .findViewById(R.id.grid_item_image);

        String mobile = mobileValues[position];
        //Spannable spn = (Spannable) textView.getText();
        SpannableString spannable = new SpannableString(mobile);

        if (mobile.equals("A")) {
            //spannable.setSpan(new ForegroundColorSpan(Color.RED), 0, mobile.length(), 0);
            //spn.setSpan(new BackgroundColorSpan(Color.RED), 0, 7,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            //spn.setSpan(new StyleSpan(android.graphics.Typeface.BOLD_ITALIC),0, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            //imageView.setImageResource(R.drawable.windows_logo);
        }
        else if (mobile.equals("B")) {
            //imageView.setImageResource(R.drawable.ios_logo);
        }
        else if (mobile.equals("C")) {
            //imageView.setImageResource(R.drawable.blackberry_logo);
        }
        else if (mobile.equals("D")) {
            //imageView.setImageResource(R.drawable.blackberry_logo);
        }
        else if (mobile.equals("E")) {
            //imageView.setImageResource(R.drawable.blackberry_logo);
        }
        else if (mobile.equals("F")) {
            //imageView.setImageResource(R.drawable.blackberry_logo);
        }
        else if (mobile.equals("G")) {
            //imageView.setImageResource(R.drawable.blackberry_logo);
        }
        else if (mobile.equals("H")) {
            //imageView.setImageResource(R.drawable.blackberry_logo);
        }
        else if (mobile.equals("I")) {
            //imageView.setImageResource(R.drawable.blackberry_logo);
        }
        else if (mobile.equals("J")) {
            //imageView.setImageResource(R.drawable.blackberry_logo);
        }else {
            //imageView.setImageResource(R.drawable.android_logo);
        }

    } else {
        gridView = (View) convertView;
    }

    return gridView;
}

解决方案

Spannable wordtoSpan = new SpannableString("A");        

wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

textView.setText(wordtoSpan);
