tekst dla markizy dynamicznie

Question

Czy można dodać tekst z kodowania java widoku listy do marquee scroll w systemie Android. Jeśli tak, proszę dać mi znać, w jaki sposób?

W razie potrzeby opublikuję użyty kod. To był XML ListView jest następująca

<?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>

Answer 1

Jeśli trzeba przenieść tekst wokół, może to pomoże:

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

Jeśli masz TextView z tekstem, który jest zbyt duży i chcesz go do poruszania się więc ludzie mogą przeczytać całość, spróbuj android:ellipsize="marquee" w pliku xml, lub w kodzie Java: textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);

Answer 2

Jeśli biblioteki Android nie są wystarczające, zawsze można użyć kodu Java. Utwórz klasę wątków, która pobiera widoki i zmienia warunki w czasie. Możesz stworzyć intencję, aby zadzwonić do tej klasy.

Answer 3

Możesz użyć TextSwitcher i zastosować animację na nim.

Spróbuj poniżej kodu:

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; 
} 

Można zdefiniować własne animacje, aby uzyskać efekt marquee.

Answer 4

Oto przykład

<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" /> 

w Javie (Jeśli używasz ListView i wiążące adaptera, a następnie w getview gdy u napompowania układ i jego widoku komponentu, ustawić wybraną flagę true do twojego TextView.)

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