在Android Textview中为不同的超链接使用不同的颜色

一万年来谁著史，三千里外欲封侯。这篇文章主要讲述在Android Textview中为不同的超链接使用不同的颜色相关的知识，希望能为你提供帮助。
我知道我可以通过设置更改textview级别的超链接颜色：

yourText.setLinkTextColor(Color.RED);

在Textview中，我的应用程序中可以有多个超链接。我想为每个超链接文本定义不同的颜色。不幸的是，使用

<
font color ...>

does不起作用。有任何想法吗？谢谢！
答案

String myString = "I accept the Terms of Use, Privacy Policy and I agree"; SpannableString ss = new SpannableString(myString); ClickableSpan clickableSpan = new TouchableSpan(normalColor, touchColor, pressedColor) { @Override public void onClick(View widget) { //perform your action to open webview or whatever } }; ClickableSpan clickableSpan2 = new TouchableSpan(normalColor, touchColor, pressedColor) { @Override public void onClick(View widget) { //perform your action to open webview or whatever } }; ss.setSpan(clickableSpan, 13, 25, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); ss.setSpan(clickableSpan2, 26, 41, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); textView.text = ss; textView.movementMethod =new LinkTouchMovementMethod();

说明

ss.setSpan(clickableSpan, 13, 25, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

这将使

点击。同样，第二个跨度将会产生

可点击我的示例字符串。您可以根据需要使用normal color，touchColor和pressedColor。
touchable span.java

public abstract class TouchableSpan extends ClickableSpan { private boolean mIsPressed; private int mPressedBackgroundColor; private int mNormalTextColor; private int mPressedTextColor; public TouchableSpan(int normalTextColor, int pressedTextColor, int pressedBackgroundColor) { mNormalTextColor = normalTextColor; mPressedTextColor = pressedTextColor; mPressedBackgroundColor = 0xffeeeeee; }public void setPressed(boolean isSelected) { mIsPressed = isSelected; }@Override public void updateDrawState(TextPaint ds) { super.updateDrawState(ds); ds.setColor(mIsPressed ? mPressedTextColor : mNormalTextColor); ds.bgColor = mIsPressed ? mPressedBackgroundColor : Color.TRANSPARENT; ds.setUnderlineText(false); } }

【在Android Textview中为不同的超链接使用不同的颜色】link touch movement method.Java

public class LinkTouchMovementMethod extends LinkMovementMethod { private TouchableSpan mPressedSpan; @Override public boolean onTouchEvent(TextView textView, Spannable spannable, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN) { mPressedSpan = getPressedSpan(textView, spannable, event); if (mPressedSpan != null) { mPressedSpan.setPressed(true); Selection.setSelection(spannable, spannable.getSpanStart(mPressedSpan), spannable.getSpanEnd(mPressedSpan)); } } else if (event.getAction() == MotionEvent.ACTION_MOVE) { TouchableSpan touchedSpan = getPressedSpan(textView, spannable, event); if (mPressedSpan != null & & touchedSpan != mPressedSpan) { mPressedSpan.setPressed(false); mPressedSpan = null; Selection.removeSelection(spannable); } } else { if (mPressedSpan != null) { mPressedSpan.setPressed(false); super.onTouchEvent(textView, spannable, event); } mPressedSpan = null; Selection.removeSelection(spannable); } return true; }private TouchableSpan getPressedSpan(TextView textView, Spannable spannable, MotionEvent event) {int x = (int) event.getX(); int y = (int) event.getY(); x -= textView.getTotalPaddingLeft(); y -= textView.getTotalPaddingTop(); x += textView.getScrollX(); y += textView.getScrollY(); Layout layout = textView.getLayout(); int line = layout.getLineForVertical(y); int off = layout.getOffsetForHorizontal(line, x); TouchableSpan[] link = spannable.getSpans(off, off, TouchableSpan.class); TouchableSpan touchedSpan = null; if (link.length > 0) { touchedSpan = link[0]; } return touchedSpan; } }
