我有一个带有锚点的html字符串的textview.当我单击textview时我想调用例如一个名为A的方法,当我单击textview中的一个链接时,我想调用一个名为B的方法.我得到了这个工作但是我遇到了一个问题：当我点击一个链接时,方法调用B,但也调用方法A.当我点击链接时,如何确保只调用方法B而不是B和A？
我的代码：
for (int i = 0; i < ingevoegd.length(); i++) {
JSONObject soortingevoegd = ingevoegd.getJSONObject(i);
String type = soortingevoegd.getString("type");
if (type.equals("Vis")) {
String link = "<a href = 'com.aquariumzoeken.pro://Soortweergave?selected="
+ naam + "&type=Vis" + "'>" + naam + "</a>";
text = text.replaceAll(naam,link);
}
}
TextView texttv = (TextView) v.findViewById(R.id.textviewer);
texttv.setText(Html.fromHtml(text));
texttv.setMovementMethod(LinkMovementMethod.getInstance());
和textview onclicklistener：
texttv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
switchToEditMode sw = new switchToEditMode();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});

解决方法
我为你做了黑客攻击,试试这个代码吧！
说明：
1.使用自定义的ClickableSpan来处理点击网址.
2.clickablespan将在textview之前处理click事件,在单击链接时创建一个标志.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView textView = (TextView) findViewById(R.id.main_text);
textView.setMovementMethod(LinkMovementMethod.getInstance());
CharSequence charSequence = textView.getText();
SpannableStringBuilder sp = new SpannableStringBuilder(charSequence);
URLSpan[] spans = sp.getSpans(0,charSequence.length(),URLSpan.class);
for (URLSpan urlSpan : spans) {
MySpan mySpan = new MySpan(urlSpan.getURL());
sp.setSpan(mySpan,sp.getSpanStart(urlSpan),sp.getSpanEnd(urlSpan),Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
}
textView.setText(sp);
textView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// 2.if clicking a link
if (!isClickingLink) {
Log.w("log","not clicking link");
}
isClickingLink = false;
}
});
}
private boolean isClickingLink = false;
private class MySpan extends ClickableSpan {
private String mUrl;
public MySpan(String url) {
super();
mUrl = url;
}
@Override
public void onClick(View widget) {
isClickingLink = true;
// 1. do url click
}
}
