這是怎麼製作多種顏色和字:
SpannableStringBuilder builder = new SpannableStringBuilder();
String red = "this is red";
SpannableString redSpannable= new SpannableString(red);
redSpannable.setSpan(new ForegroundColorSpan(Color.RED), 0, red.length(), 0);
builder.append(redSpannable);
String white = "this is white";
SpannableString whiteSpannable= new SpannableString(white);
whiteSpannable.setSpan(new ForegroundColorSpan(Color.WHITE), 0, white.length(), 0);
builder.append(whiteSpannable);
String blue = "this is blue";
SpannableString blueSpannable = new SpannableString(blue);
blueSpannable.setSpan(new ForegroundColorSpan(Color.BLUE), 0, blue.length(), 0); builder.append(blueSpannable); mTextView.setText(builder, BufferType.SPANNABLE);
對於現象單詞指標做如下:
int first = str.indexOf("hi");
int next = str.indexOf("hi", first+1);
read api
這樣做是爲了讓所有的指標和它們上色
span.toString()的indexOf( 「名稱」); span.setSpan(...) –
