如何在 java 中添加字体样式和粗体

Question

Well, in the title is everything (I don't really know how to implement bold and font style in this specific code), code:

spinnerCategory.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                ((TextView) parent.getChildAt(0)).setTextColor(Color.parseColor("#383163"));                                                                            
            }

        @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }
        });

Answer 1

You can use html code to add text and to represent bold text (using <b> ), convert this information into your TextView using Html.fromHtml()

textView.setText(Html.fromHtml("Hello <b>world</b>, it is <b>vonAlt</b>"));

this is an example applied to your code:

spinnerCategory.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                ((TextView) parent.getChildAt(0)).setTextColor(Color.parseColor("#383163"));                                                                            
            }

        @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }
        });
