The following API s are available for us to use in Spannable String:

Well, there are still a lot of examples. Here is the simplest example. Other parameter calls can be made by Baidu Google~1). The simplest example is: Running Effect Chart:

Implementation code:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TextView t1 = (TextView) findViewById(R.id.txtOne);
        TextView t2 = (TextView) findViewById(R.id.txtTwo);

        SpannableString span = new SpannableString("Red Telephone Italic Delete Line Green Underline Picture:.");
        //1. Set the background color. When setSpan, you need to specify flag, Spanned. SPAN_EXCLUSIVE_EXCLUSIVE (neither before nor after)
        span.setSpan(new ForegroundColorSpan(Color.RED), 0, 2, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        //2. Marking text with hyperlinks
        span.setSpan(new URLSpan("tel:4155551212"), 2, 5, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        //3. Mark text with style (italics)
        span.setSpan(new StyleSpan(Typeface.BOLD_ITALIC), 5, 7, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        //4. Marking Text with Delete Lines
        span.setSpan(new StrikethroughSpan(), 7, 10, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        //5. Mark text with underscores
        span.setSpan(new UnderlineSpan(), 10, 16, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        //6. Mark with color
        span.setSpan(new ForegroundColorSpan(Color.GREEN), 10, 13,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        //7. //Get Drawable Resources
        Drawable d = getResources().getDrawable(R.drawable.icon);
        d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
        //8. Create ImageSpan and replace text with ImageSpan
        ImageSpan imgspan = new ImageSpan(d, ImageSpan.ALIGN_BASELINE);
        span.setSpan(imgspan, 18, 19, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
        t1.setText(span);
    }
}

2) Realize part of clickable TextView believe that friends who have played QQ space and Wechat Friendship Circle are not unfamiliar with the following things, we can click on the corresponding users and then enter to view user-related information, right?

Let's write a simple example to achieve the following effect:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TextView t1 = (TextView) findViewById(R.id.txtOne);

        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < 20; i++) {
            sb.append("Good friend" + i + "，");
        }

        String likeUsers = sb.substring(0, sb.lastIndexOf("，")).toString();
        t1.setMovementMethod(LinkMovementMethod.getInstance());
        t1.setText(addClickPart(likeUsers), TextView.BufferType.SPANNABLE);
    }

    //Define a way to click on each part of the text
    private SpannableStringBuilder addClickPart(String str) {
        //Praise the icon, there is no material here, find a smiling face instead.~
        ImageSpan imgspan = new ImageSpan(MainActivity.this, R.drawable.ic_widget_face);
        SpannableString spanStr = new SpannableString("p.");
        spanStr.setSpan(imgspan, 0, 1, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

        //Create a Spannable StringBuilder object that connects multiple strings
        SpannableStringBuilder ssb = new SpannableStringBuilder(spanStr);
        ssb.append(str);
        String[] likeUsers = str.split("，");
        if (likeUsers.length > 0) {
            for (int i = 0; i < likeUsers.length; i++) {
                final String name = likeUsers[i];
                final int start = str.indexOf(name) + spanStr.length();
                ssb.setSpan(new ClickableSpan() {
                    @Override
                    public void onClick(View widget) {
                        Toast.makeText(MainActivity.this, name,
                                Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void updateDrawState(TextPaint ds) {
                        super.updateDrawState(ds);
                        //Delete the underline and set the font color to blue
                        ds.setColor(Color.BLUE);
                        ds.setUnderlineText(false);
                    }
                },start,start + name.length(),0);
            }
        }
    return ssb.append("etc." + likeUsers.length + "Personally, I think it's great.");
    }
}
