Tweet o = tweets.get(position);
TextView tt = (TextView) v.findViewById(R.id.toptext);
//TextView bt = (TextView) v.findViewById(R.id.bottomtext);
EditText bt =(EditText)findViewById(R.id.bottomtext);
bt.setText(o.author);
Spannable spn = (Spannable) bt.getText();
spn.setSpan(new StyleSpan(android.graphics.Typeface.BOLD_ITALIC)
, 0, 100, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
//bt.setText(o.author);
tt.setText(o.content);
我正在我的Android应用中设置Twitter数据。我想使用Spannable使字体变粗和斜体,但它不起作用,会出现错误。我该怎么做?
