9月10日更新-更改所有出现的目标字符串
这样的通用方法将起作用：
public class SpanTest extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); String dispStr = "This has the string ABCDEF in it nSo does this :ABCDEF - see!nAnd again ABCD here"; TextView tv = (TextView) findViewById(R.id.textView1); tv.setText(dispStr); changeTextinView(tv, "ABC", Color.RED); } private void changeTextinView(TextView tv, String target, int colour) { String vString = (String) tv.getText(); int startSpan = 0, endSpan = 0; Spannable spanRange = new SpannableString(vString); while (true) { startSpan = vString.indexOf(target, endSpan); ForegroundColorSpan foreColour = new ForegroundColorSpan(colour); // Need a NEW span object every loop, else it just moves the span if (startSpan < 0) break; endSpan = startSpan + target.length(); spanRange.setSpan(foreColour, startSpan, endSpan, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); } tv.setText(spanRange); }}。
