在Android中EditText用于編輯文本，TextView用于顯示文本，但是有時候我們需要對其中的文本進行樣式等方面的設置。Android為我們提供了SpannableString類來對指定文本進行處理。 1) ForegroundColorSpan? ? ? ??文本顏色 ~~~ private void setForegroundColorSpan() { SpannableString spanString = new SpannableString("前景色"); ForegroundColorSpan span = new ForegroundColorSpan(Color.BLUE); spanString.setSpan(span, 0, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); tv.append(spanString); } ~~~ 2) BackgroundColorSpan文本背景色? ~~~ private void setBackgroundColorSpan() { SpannableString spanString = new SpannableString("背景色"); BackgroundColorSpan span = new BackgroundColorSpan(Color.YELLOW); spanString.setSpan(span, 0, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); tv.append(spanString); } ~~~ 3) StyleSpan ? ? ? ??字體樣式：粗體、斜體等 ~~~ private void setStyleSpan() { SpannableString spanString = new SpannableString("粗體斜體"); StyleSpan span = new StyleSpan(Typeface.BOLD_ITALIC); spanString.setSpan(span, 0, 4, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); tv.append(spanString); } ~~~ 4) RelativeSizeSpan ? ? ? ??相對大小 ~~~ private void setRelativeFontSpan() { SpannableString spanString = new SpannableString("字體相對大小"); spanString.setSpan(new RelativeSizeSpan(2.5f), 0, 6,Spannable.SPAN_INCLUSIVE_EXCLUSIVE); tv.append(spanString); } ~~~ 5) TypefaceSpan ? ? ? ??文本字體 ~~~ private void setTypefaceSpan() { SpannableString spanString = new SpannableString("文本字體"); spanString.setSpan(new TypefaceSpan("monospace"), 0, 4, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); tv.append(spanText); } ~~~ 6) URLSpan 文本超鏈接 ~~~ private void addUrlSpan() { SpannableString spanString = new SpannableString("超鏈接"); URLSpan span = new URLSpan("http://www.baidu.com"); spanString.setSpan(span, 0, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); tv.append(spanString); } ~~~ 7) ImageSpan ? ? ? ? 圖片 ~~~ private void addImageSpan() { SpannableString spanString = new SpannableString(" "); Drawable d = getResources().getDrawable(R.drawable.ic_launcher); d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight()); ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BASELINE); spanString.setSpan(span, 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); tv.append(spanString); } ~~~ 8) ClickableSpan ? ? ? ? ? ? ? ? 文本有點擊事件 ~~~ private TextView textView; textView = (TextView)this.findViewById(R.id.textView); String text = "顯示Activity"; SpannableString spannableString = new SpannableString(text); spannableString.setSpan(new ClickableSpan() { @Override public void onClick(View widget) { Intent intent = new Intent(Main.this,OtherActivity.class); startActivity(intent); } // 表示點擊整個text的長度都有效觸發這個事件 }, 0, text.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); textView.setText(spannableString); textView.setMovementMethod(LinkMovementMethod.getInstance()); ~~~ 9) UnderlineSpan ? ? ? ??下劃線 ~~~ private void addUnderLineSpan() { SpannableString spanString = new SpannableString("下劃線"); UnderlineSpan span = new UnderlineSpan(); spanString.setSpan(span, 0, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); tv.append(spanString); } ~~~ 10) StrikethroughSpan ? ? ? ??刪除線 ~~~ private void addStrikeSpan() { SpannableString spanString = new SpannableString("刪除線"); StrikethroughSpan span = new StrikethroughSpan(); spanString.setSpan(span, 0, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); tv.append(spanString); } ~~~ 11) SuggestionSpan 相當于占位符 12) MaskFilterSpan 修飾效果，如模糊(BlurMaskFilter)、浮雕(EmbossMaskFilter) 13) RasterizerSpan ? ? ? ??光柵效果 14) AbsoluteSizeSpan ? ? ? ??絕對大小（文本字體） ~~~ private void setAbsoluteFontSpan() { SpannableString spannableString = new SpannableString("40號字體"); AbsoluteSizeSpan absoluteSizeSpan = new AbsoluteSizeSpan(40); spannableString.setSpan(absoluteSizeSpan, 0, 5, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); editText.append(spannableString); } ~~~ 15) DynamicDrawableSpan ? ?設置圖片，基于文本基線或底部對齊。 16) TextAppearanceSpan 文本外貌（包括字體、大小、樣式和顏色） ~~~ private void setTextAppearanceSpan() { SpannableString spanString = new SpannableString("文本外貌"); TextAppearanceSpan textAppearanceSpan = new TextAppearanceSpan(this, android.R.style.TextAppearance_Medium)； spanString.setSpan(textAppearanceSpan, 0, 4, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); tv.append(spanString); } ~~~
