Question

我有一个视图显示textview并启用自动链接。

<TextView
   android:id="@+id/txt_contents"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:layout_margin="30dp"
   android:textColor="@color/txt_code_itemlist"
   android:autoLink="web"
   android:textSize="22sp" />

现在，当我从textview点击链接时，它将打开浏览器。但是当我点击相同的链接时，我想找到打开新活动的方法。

Answer 1

完美的工作：

    tvoublie.setPaintFlags(tvoublie.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);
            Linkify.addLinks(tvoublie, Linkify.ALL);
            tvoublie.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Log.i("LoginActivity", "Sign Up Activity activated.");
                    // this is where you should start the new Activity
                   Intent intent = new Intent(CurrentActivity.this,YourNewActivity.class);
                   startActivity(intent);  

                }
            });

这用url打开o浏览器：

register.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent();
                intent.setAction(Intent.ACTION_VIEW);
                intent.addCategory(Intent.CATEGORY_BROWSABLE);
                intent.setData(Uri.parse("https://www.google.com"));
                startActivity(intent);
            }
        });

您可以在TextView中使用Linkify，

    TextView sample = (TextView) findViewById(R.id.txt_contents);

    String webUrlOrText = "www.google.com a search Engine";
    Spannable spannableString = new SpannableString(Html.fromHtml(webUrlOrText));



    Linkify.addLinks(spannableString, Linkify.WEB_URLS); // It will make only Weblink clickable

    URLSpan[] urlSpans = spannableString.getSpans(0, spannableString.length(), URLSpan.class);
    for (URLSpan urlSpan : urlSpans) {
        LinkSpan linkSpan = new LinkSpan(urlSpan.getURL());
        int spanStart = spannableString.getSpanStart(urlSpan);
        int spanEnd = spannableString.getSpanEnd(urlSpan);
        spannableString.setSpan(linkSpan, spanStart, spanEnd, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        spannableString.removeSpan(urlSpan);
    }

    sample.setText(spannableString);
    sample.setMovementMethod(LinkMovementMethod.getInstance());

和LinkSpan类，

private class LinkSpan extends URLSpan {
    private LinkSpan(String url) {
        super(url);
    }

    @Override
    public void onClick(View view) {
        String url = getURL();

        if (url != null) {
           // Open the Activity here
           Log.d(TAG, "Url clicked");
        }
    }
}

您可以添加此项。

text_view.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
          Intent intent = new Intent(CurrentActivity.this,YourNewActivity.class);
          startActivity(intent);  
        }
    });

希望这有帮助。

使用以下代码识别单击的文本部分

tv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
    ClassroomLog.log(TAG, "Textview Click listener ");
    if (tv.getSelectionStart() == -1 && tv.getSelectionEnd() == -1) {
        //This condition will satisfy only when it is not an autolinked text
        //Fired only when you touch the part of the text that is not hyperlinked 
    }
}

}）;

并编写代码以使用任何一种情况执行任何操作

当从textview点击链接时，Android会打开新活动（自动链接）
