从画廊中选择字体并在下一页显示

Question

我想根据是否从水平gridview中选择的类型face的字体来设置字体的字体，该字体是否具有常规字体类型等字体类型等，另一个水平gridview具有霓虹灯字体字体。字形没问题，但是当我按下后退按钮并选择了普通的fonttype时，所选字体不会按需要显示。

font_style_ga =（画廊）findviewbyid（r.id.font_style_ga）;

    font_style_ga.setAdapter(new FontStyle(this));

font_style_ga.setOnitemClickListener（新的OnItemClickListener（）{

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1,
                                int position, long arg3) {

            if (IsNativeAdVisible) {
                return;
            }
            if (position == 0) {
                externalFont = Typeface.createFromAsset(getAssets(),
                        "Creator_Campotype_smcp.otf");
            } else if (position == 1) {
                externalFont = Typeface.createFromAsset(getAssets(),
                        "Gangnam.ttf");
            } 

similarty for Neontypeface as as neon_font_ga.setOnitemClickListener（新的OnItemClickListener（）{ @Override ＆lt;？

            if (IsNativeAdVisible) {
                return;
            }
            if(position==0){
                neonFonts=Typeface.createFromAsset(getAssets(),
                        "Neony_font.ttf");
            }


                NeontypeFaceName= neonTypeList[position];
                text_edt.setTextSize(textsize);
                text_edt.setTypeface(neonFonts);



        }
    });


Intent intent = new Intent(TextActivity.this,
                            FirstActivity.class);
                    intent.putExtra("text", edit_text_str);
                    intent.putExtra("textcolor", textcolor);
                    intent.putExtra("textsize", textsize);
                    intent.putExtra("typeface", typeFaceName);
                    intent.putExtra("neonTypeface",NeontypeFaceName);
                    startActivity(intent);

public void onItemClick（ adapterView /code>或neontypefacename是使用否则条件设置的，

if (bundleIntent != null) {


        adText.setText(bundleIntent.getExtras().getString("text"));


        if (bundleIntent.getExtras().getString("typeface") == null ) {

            adText.setTypeface(Typeface.DEFAULT);

        } else {

            Typeface typeFace = Typeface.createFromAsset(getAssets(),
                    bundleIntent.getExtras().getString("typeface"));

            adText.setTypeface(typeFace);

        }

        adText.setTextSize(bundleIntent.getExtras().getFloat("textsize"));

        int color = bundleIntent.getExtras().getInt("textcolor");

        if (color == 0) {

            color = Color.BLACK;
        }
        adText.setTextColor(color);


        if(bundleIntent.getExtras().getString("neonTypeface")!=null  ){
            Typeface typeFace = Typeface.createFromAsset(getAssets(),
                    bundleIntent.getExtras().getString("neonTypeface"));

            adText.setTypeface(typeFace);
            adText.setShadowLayer(11,2,-2,color);


        }else if(bundleIntent.getExtras().getString("typeface")!=null){
            Typeface typeFace = Typeface.createFromAsset(getAssets(),
                    bundleIntent.getExtras().getString("typeface"));

            adText.setTypeface(typeFace);
        }

但是在向后下方和更改字体后将无法选择字体。请帮忙
