问题:

I want to make a link for a textview text like Google. Is there anyway to make link like this. (i.e) When clicking on the word Google it should open the appropriate link. Any ideas are welcome.

回答1:

Try this, and let me know what happen..

Using java code:

TextView textView =(TextView)findViewById(R.id.textView);
textView.setClickable(true);
textView.setMovementMethod(LinkMovementMethod.getInstance());
String text = "<a href='http://www.google.com'> Google </a>";
textView.setText(Html.fromHtml(text));

From API level >= 24 onwards Html.fromHtml(String source) is deprecated instead use fromHtml(String, int),

textView.setText(Html.fromHtml(text, Html.FROM_HTML_MODE_COMPACT));

Or in layout xml file, inside your TextView widget attributes

android:autoLink="web"
android:linksClickable="true"


回答2:

use android:autoLink="web" in your TextView's xml. It should automatically convert urls click-able (if found in text)

All tested and working 100%
Solution: android:autoLink="web"
below is a complete example

Sample Layout Xml

    <TextView
        android:id="@+id/txtLostpassword"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:autoLink="email"
        android:gravity="center"
        android:padding="20px"
        android:text="@string/lostpassword"
        android:textAppearance="?android:attr/textAppearanceSmall" />

    <TextView
        android:id="@+id/txtLostpassword"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:autoLink="web"
        android:gravity="center"
        android:padding="20px"
        android:text="@string/defaultpassword"
        android:textAppearance="?android:attr/textAppearanceSmall" />

String in string.xml

<string name="lostpassword">If you lost your password please contact <a href="mailto:support@cleverfinger.com.au?Subject=Lost%20Password" target="_top">support@cleverfinger.com.au</a></string>

<string name="defaultpassword">User Guide <a href="http://www.cleverfinger.com.au/user-guide/">http://www.cleverfinger.com.au/user-guide/</a></string>

This can also be done by using the default property of Textview

android:autoLink="email"

Note :- Html.fromHtml is deprecated in Android N

You need to do check and support Android N and higher versions of Android

                  //Set clickable true
                 tagHeading.setClickable(true);

                  //Handlle click event
                  tagHeading.setMovementMethod(LinkMovementMethod.getInstance());

                if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
                    tagHeading.setText(Html.fromHtml("<a href='https://github.com/hiteshsahu'>https://github.com/hiteshsahu</a>", Html.FROM_HTML_MODE_LEGACY));
                } else {
                    tagHeading.setText(Html.fromHtml("<a href='https://github.com/hiteshsahu'>https://github.com/hiteshsahu</a>"));
                }

Alternatively

You can don't want to id programmatically add autoLink flag on TextView.

android:autoLink="web"

android:linksClickable="true"

This way You don't need to add <a href='somelink'> tags.

Which is a disadvantage, if you want to add hyperlink on a text you can't do it this way. eg you can't do something like this:- [hiteshsahu][1]

           <TextView
                android:id="@+id/tag_info"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_below="@+id/tag_ll"
                android:layout_gravity="left"
                android:layout_margin="10dp"
                android:autoLink="web"
                android:linksClickable="true"
                android:text="https://github.com/hiteshsahu"
                android:textColor="@color/secondary_text" />

The result from both approach:-

For Latest version of SDK fromHtml is deprecated Use below line

String yourtext = "<a style='text-decoration:underline' href='http://www.sample.com'> Sample Website </a>";
    if (Build.VERSION.SDK_INT >= 24) {
        textView.setText(Html.fromHtml(yourtext, Html.FROM_HTML_MODE_LEGACY));
    } else {
        textView.setText(Html.fromHtml(yourtext));
    }
