我有一份案文,将作为蓝色通道。 当我发出指挥时,我希望以肤色(例如cyan)来写,并用不同颜色(例如红色)得到的答复。
这样做是可能的,如果是,如何?
我读到,可能采用超文本处理,但我不相信这是最佳办法,甚至可以如何这样做。

您是否真的需要是书面意见,还是能够使用清单,并在每个指挥/答复的名单中增加新的一行?
请
package com.c0deattack;
import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.text.Spannable;
import android.text.style.ForegroundColorSpan;
import android.widget.LinearLayout;
import android.widget.TextView;
public class MultipleColoursInOneTextViewActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
String command = "This is a command";
String response = "
This is a response";
tv.append(command + response);
Spannable spannableText = (Spannable) tv.getText();
spannableText.setSpan(new ForegroundColorSpan(Color.GREEN), 0, command.length(), 0);
spannableText.setSpan(new ForegroundColorSpan(Color.RED), command.length(), command.length() + response.length(), 0);
LinearLayout layout = new LinearLayout(this);
layout.addView(tv);
setContentView(layout);
}
}
因此,这表明可以这样做,但你显然要注意到,在每一指挥/电塔开始和结束时,你必须打断线断线和停工,以便你能够对其适用正确的颜色。 这对我来说不是那么困难,而是感觉到cl。
在这方面,根据C0deAttack的回答,没有什么帮助作用,这就简化了事情。
public static void appendColoredText(TextView tv, String text, int color) {
int start = tv.getText().length();
tv.append(text);
int end = tv.getText().length();
Spannable spannableText = (Spannable) tv.getText();
spannableText.setSpan(new ForegroundColorSpan(color), start, end, 0);
}
仅取代任何呼吁
textView.append("Text")
iii
appendColoredText(textView, "Text", Color.RED);
如果你使用:
textView.append(Html.fromHtml("<font color= #FFFFFF </font>"));
public static void appendColoredText(TextView tv, String text, int color) {
SpannableStringBuilder ssb = new SpannableStringBuilder();
ssb.append(text);
ssb.setSpan(new ForegroundColorSpan(color), 0, text.length(), 0);
tv.append(ssb);
}
优化 回答
我们可以创建<代码>SpannableStringBuilder 反对持有text
和color%20/code>,并使用
append(
和setSpan(
) 添加案文和彩色字体的>方法。
This will be more efficient, as it avoids creating a new Spannable object every time the method is called.
