Wie kann ich mehrere anklickbare Teile des Textes in TextView machen

Question

Wie kann ich mehrere anklickbare Teile des Textes in TextView machen. Jeder anklickbare Teil muss seine eigene Aktion haben.

Answer 1

können Sie android.text.style.ClickableSpan

SpannableString ss = new SpannableString("Hello World"); 
    ClickableSpan span1 = new ClickableSpan() { 
     @Override 
     public void onClick(View textView) { 
      // do some thing 
     } 
    }; 

    ClickableSpan span2 = new ClickableSpan() { 
     @Override 
     public void onClick(View textView) { 
      // do another thing 
     } 
    }; 

    ss.setSpan(span1, 0, 4, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); 
    ss.setSpan(span2, 6, 10, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); 

    textView.setText(ss); 
    textView.setMovementMethod(LinkMovementMethod.getInstance()); 

Answer 2

Ich speichere Haupttext und anklickbare Wörter in verschiedenen Ressourcen verwenden.

Strings in Ressourcen sind für einige Konfigurationen nicht vorhanden.

String[] links = new String[3]; 

    links[0] = cntx.getString(cntx.getResources().getIdentifier("footerLink1", "string", cntx.getPackageName())); 
    links[1] = cntx.getString(cntx.getResources().getIdentifier("footerLink2", "string", cntx.getPackageName())); 
    links[2] = cntx.getString(cntx.getResources().getIdentifier("footerLink3", "string", cntx.getPackageName())); 
    String text = String.format(cntx.getString(cntx.getResources().getIdentifier("footerDisclaimer", "string", cntx.getPackageName())), links[0], links[1], links[2]); 
    SpannableString ss = new SpannableString(text); 
    setSpanOnLink(ss, links[0], new ClickableSpan() { 
     @Override 
     public void onClick(View textView) { 
      Log.i("Disclaimer Footer", "1 click"); 
      //TODO run item 
     } 
    }); 
    setSpanOnLink(ss, links[1], new ClickableSpan() { 
     @Override 
     public void onClick(View textView) { 
      Log.i("Disclaimer Footer", "2 click"); 
      //TODO run item 
     } 
    }); 
    setSpanOnLink(ss, links[2], new ClickableSpan() { 
     @Override 
     public void onClick(View textView) { 
      Log.i("Disclaimer Footer", "3click"); 
      //TODO run item 
     } 
    }); 

    TextView t1 = new TextView(cntx); 
    t1.setTextSize(TypedValue.COMPLEX_UNIT_SP, 8); 
    t1.setText(ss); 
    t1.setMovementMethod(LinkMovementMethod.getInstance()); 

private void setSpanOnLink(SpannableString ss, String link, ClickableSpan cs) { 
     String text = ss.toString(); 
     int start = text.indexOf(link); 
     int end = start + link.length(); 
     ss.setSpan(cs, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); 
    }

Dies ist für mich arbeiten:

in xml:

<TextView 
     android:id="@+id/tv_by_continuing_str" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginTop="8dp" 
     android:layout_marginLeft="8dp" 
     android:layout_marginRight="8dp" 
     android:textSize="15sp" 
     tools:text="Test msg 1 2, 3" 
     android:textColor="@color/translucent_less_white3" 
     android:textColorLink="@color/white" 
     android:gravity="center|bottom" 
     android:layout_above="@+id/btn_privacy_continue" /> 

In strings.xml

< string name="by_continuing_str2">< ! [ CDATA[By continuing to use this app, you agree to our <a href="https://go.test.com" style="color:gray"/> Privacy Statement </a> and <a href="https://go.test.com" style="color:gray"/>Services Agreement.]]></string> 

der Tätigkeit:

TextView tv_by_continuing = (TextView) findViewById(R.id.tv_by_continuing); 
tv_by_continuing.setText(Html.fromHtml(getString(R.string.by_continuing_str2))); 
tv_by_continuing.setMovementMethod(LinkMovementMethod.getInstance());
