Text für Laufschrift dynamisch

Question

Ist es möglich, Text von Java-Codierung einer Listenansicht zu Festzelt Scroll in Android hinzuzufügen. Wenn ja, kannst du mir bitte sagen wie?

Bei Bedarf werde ich den verwendeten Code veröffentlichen. Dies war der XML für Listview verwendet wird, ist als

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" > 
    <LinearLayout 
     android:id="@+id/linearLayout1" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:orientation="horizontal" > 
    </LinearLayout> 
    <ListView 
     android:id="@+id/audiolist_listView" 
     android:layout_width="fill_parent" 
     android:layout_height="0dp" 
     android:layout_gravity="bottom" 
     android:layout_weight="1" 
     android:background="@drawable/backgroundimg" 
     android:divider="@drawable/gradient" 
     android:dividerHeight="1dp" 
     android:scrollbars="vertical" > 
    </ListView> 

</LinearLayout> 

folgt

Die Java-Klasse für Listview ist wie folgt

Answer 1

Wenn Sie Text bewegen müssen, vielleicht wird dies dazu beitragen:

http://developer.android.com/guide/topics/resources/animation-resource.html#translate-element

Wenn Sie eine Textview mit einem Text, der zu groß ist und Sie wollen es, sich zu bewegen, damit die Menschen die ganze Sache lesen können, versuchen android:ellipsize="marquee" in der XML-Datei oder in der Java-Code: textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);

Answer 2

Wenn die Android-Bibliotheken nicht genug sind, können Sie immer das Java über Codierung verwenden. Erstellen Sie eine Thread-Klasse, die die Ansichten abruft und die Bedingungen im Laufe der Zeit ändert. Sie können eine Absicht erstellen, um diese Klasse aufzurufen.

Answer 3

Sie können den TextSwitcher verwenden und die Animation darauf anwenden.

Try unten Code:

public class TextSwitcherActivity extends Activity implements ViewSwitcher.ViewFactory, 
    View.OnClickListener      
    { 
private TextSwitcher m_switcher; 
private Button m_nextButton; 
private int m_counter = 0; 

@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    m_switcher = (TextSwitcher) findViewById(R.id.tsSwitcher); 
    m_switcher.setFactory(this); 

    Animation in = AnimationUtils.loadAnimation(this, android.R.anim.fade_in); 
    Animation out = AnimationUtils.loadAnimation(this, android.R.anim.fade_out); 
    m_switcher.setInAnimation(in); 
    m_switcher.setOutAnimation(out); 

    m_nextButton = (Button) findViewById(R.id.next); 
    m_nextButton.setOnClickListener(this); 
    updateCounter(); 
} 

/** 
* Update counter value 
*/ 
public void onClick(View v) 
{ 
    m_counter++; 
    updateCounter(); 
} 

/** 
* Set text on textswitcher 
*/ 
private void updateCounter() 
{ 
    m_switcher.setText(String.valueOf(m_counter)); 
} 

public View makeView() 
{ 
    TextView t = new TextView(this); 
    t.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL); 
    t.setTextSize(36); 
    return t; 
} 

Sie können Ihre eigenen Animationen definieren den Marquee-Effekt zu erhalten.

Answer 4

Hier wird das Beispiel

<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 
<TextView 
    android:id="@+id/mywidget" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentRight="true" 
    android:lines="1" 
    android:ellipsize="marquee" 
    android:fadingEdge="horizontal" 
    android:marqueeRepeatLimit="marquee_forever" 
    android:scrollHorizontally="true" 
    android:textColor="#ff4500" 
    android:text="Simple application that shows how to use marquee, with a long text" /> 

in Java (Wenn Sie eine Listenansicht und die Bindung einen Adapter verwenden, dann in GetView wenn u-Layout und die Ansichtskomponente aufzublasen, stellen die ausgewählte Flag treu zu Ihrem TextView.)

tv = (TextView) this.findViewById(R.id.tv); 
    tv.setSelected(true);
