văn bản cho marquee động

Question

Có thể thêm văn bản từ mã hóa java của chế độ xem danh sách để di chuyển marquee trong Android hay không. Nếu có, bạn có thể cho tôi biết bằng cách nào không?

Nếu cần, tôi sẽ đăng mã được sử dụng. Đây là XML cho listview sử dụng như sau

<?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

Nếu bạn cần di chuyển văn bản xung quanh, có lẽ đây sẽ giúp:

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

Nếu bạn có một TextView với một văn bản đó là quá lớn và bạn muốn nó di chuyển xung quanh để mọi người có thể đọc toàn bộ điều, hãy thử android:ellipsize="marquee" trong file .xml, hoặc trong mã Java: textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);

Answer 2

Nếu thư viện Android không đủ, bạn luôn có thể sử dụng java thông qua mã hóa. Tạo một lớp chuỗi để có được các khung nhìn và thay đổi các điều kiện theo thời gian. Bạn có thể tạo ý định gọi lớp đó.

Answer 3

Bạn có thể sử dụng TextSwitcher và áp dụng hoạt ảnh trên đó.

Hãy thử bên dưới mã:

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; 
} 

Bạn có thể xác định hình ảnh động riêng của mình để có được những hiệu ứng marquee.

Answer 4

Dưới đây là ví dụ

<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" /> 

Trong java (Nếu bạn đang sử dụng một listview và ràng buộc một bộ chuyển đổi, sau đó trong getview khi u thổi phồng Layout và thành phần quan điểm của mình, đặt cờ chọn đúng với TextView của bạn.)

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