在android中的TextView中可单击的单词

Question

我有TextView文本,动态更改.这个文本包含像<a href='myWord'>myWord</a>.我希望在点击这个"链接"之后,myWord出现在同一活动的EditText中.

这是我的代码:

txt.setText(Html.fromHtml("...<a href='link'>link</a>..."));
txt.setMovementMethod(LinkMovementMethod.getInstance());

它适用于href属性中的URL,但是另一种格式存在错误.

我在StackOverflow上发现了很多类似的问题,但所有问题都与url链接有关.在我的应用程序中,我想在活动中创建"链接".一般来说,如果依赖,我可以将标签更改为其他标签...

请帮我!谢谢!

-----已解决-----谢谢雅各布菲利普斯的想法!

将来可能会有人感兴趣.这是一个代码:

//This is my string;
String str = "<b>Text</b> which contains one <a href='#'>link</a> and another <a href='#'>link</a>";
//TextView;
TextView txt = new TextView(this);
//Split string to parts:                                        
String[] devFull = data[v.getId()][1].split("<a href='#'>");
//Adding first part:
txt.append(Html.fromHtml(devFull[0]));
//Creating array for parts with links (they amount always will devFull.length-1):
SpannableString[] link = new SpannableString[devFull.length-1];
//local vars:
ClickableSpan[] cs = new ClickableSpan[devFull.length-1];
String linkWord;
String[] devDevFull = new String[2];

for(int i=1; i<devFull.length; i++){
    //obtaining 'clear' link
    devDevFull = devFull[i].split("</a>");
    link[i-1] = new SpannableString(devDevFull[0]);
    linkWord = devDevFull[0];
    cs[i-1] = new ClickableSpan(){
        private String w = linkWord;
        @Override
        public void onClick(View widget) {
            // here you can use w (linkWord)
        }
    };
    link[i-1].setSpan(cs[i-1], 0, linkWord.length(), 0);
    txt.append(link[i-1]);
    try{
        txt.append(Html.fromHtml(devDevFull[1]));
    }
    catch(Exception e){}
}

这应该可以解决问题.只需更改您的edittext文本即可OnClickListener.它可能会减少,但这应该工作.

private void foo() {
    SpannableString link = makeLinkSpan("click here", new View.OnClickListener() {          
        @Override
        public void onClick(View v) {
            // respond to click
        }
    });

    // We need a TextView instance.        
    TextView tv = new TextView(context);   

    // Set the TextView's text     
    tv.setText("To perform action, ");

    // Append the link we created above using a function defined below.
    tv.append(link);

    // Append a period (this will not be a link).
    tv.append(".");

    // This line makes the link clickable!
    makeLinksFocusable(tv);
}

/*
 * Methods used above.
 */

private SpannableString makeLinkSpan(CharSequence text, View.OnClickListener listener) {
    SpannableString link = new SpannableString(text);
    link.setSpan(new ClickableString(listener), 0, text.length(), 
        SpannableString.SPAN_INCLUSIVE_EXCLUSIVE);
    return link;
}

private void makeLinksFocusable(TextView tv) {
    MovementMethod m = tv.getMovementMethod();  
    if ((m == null) || !(m instanceof LinkMovementMethod)) {  
        if (tv.getLinksClickable()) {  
            tv.setMovementMethod(LinkMovementMethod.getInstance());  
        }  
    }  
}

/*
 * ClickableString class 
 */

private static class ClickableString extends ClickableSpan {  
    private View.OnClickListener mListener;          
    public ClickableString(View.OnClickListener listener) {              
        mListener = listener;  
    }          
    @Override  
    public void onClick(View v) {  
        mListener.onClick(v);  
    }        
}

更好的方法是

   SpannableString ss = new SpannableString("Android is a Software stack");
    ClickableSpan clickableSpan = new ClickableSpan() {
        @Override
        public void onClick(View textView) {
            startActivity(new Intent(MyActivity.this, NextActivity.class));
        }
    };
    ss.setSpan(clickableSpan, 22, 27, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//where 22 and 27 are the starting and ending index of the String. Now word stack is clickable 
// onClicking stack it will open NextActiivty

    TextView textView = (TextView) findViewById(R.id.hello);
    textView.setText(ss);
    textView.setMovementMethod(LinkMovementMethod.getInstance());

我所知道的最好的解决方法是创建您自己的 Button 类。您可以使按钮具有透明背景，以便用户只能看到文本。然后，当按下按钮时，将按钮的 TextColor 和 TextStyle 更改为较深的颜色并带有下划线。这将完全像链接一样工作。然后，您可以使用 startActivity 转到相应的活动。您不应使用超链接来连接到应用程序中的其他活动。
