我正在处理一个小项目,但我无法获得预期的结果。我想改变字符串的颜色奇数字和另一种颜色。有人可以帮忙吗?我离开这里是我现在的代码:
public void updateMessages() {
String groupMessage = "Admin says: Hi people\n Admin says: What's up?";
TextView groupMessageBox = (TextView) this
.findViewById(R.id.groupMessageBox);
String[] str_array = groupMessage.split("\n|\\:");
//Result str_array == Admin says, Admin says
for (int i = 0; i < str_array.length; i++) {
//Get values of array
String val1 = str_array[i];
//Only numbers pairs
if ( i % 2 == 0 ) {
//How to change the result to blue, for example?
Log.e("",val1);
}else{
Log.e("",val1);
//How to change the result to red, for example?
}
}
groupMessageBox.setText(groupMessage);
}
问候!
答案 0 :(得分:0)
如果要将val1
的颜色更改为红色,例如:
String coloredString = "<font color="#FF0000">" + val1 + "</font>";
str_array[i] = coloredString;
然后在for循环之外,你可能想重新加入文本并重置textView:
String coloredMessage = // Join the strings together
groupMessageBox.setText(Html.fromHtml(coloredMessage));
