如何在Android应用程序中使用字幕文本？
答案 0 :(得分：119)
以下是一个例子：
public class TextViewMarquee extends Activity {
private TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv = (TextView) this.findViewById(R.id.mywidget);
tv.setSelected(true); // Set focus to the textview
}
}
带有textview的xml文件：
<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:maxLines="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" />
</RelativeLayout>
答案 1 :(得分：23)
TextView textView = (TextView) this.findViewById(R.id.textview_marquee);
textView.setEllipsize(TruncateAt.MARQUEE);
textView.setText("General Information... general information... General Information");
textView.setSelected(true);
textView.setSingleLine(true);
答案 2 :(得分：22)
android:ellipsize="marquee"
这仅适用于TextView有焦点的情况。
答案 3 :(得分：10)
为了实现这一点，我必须使用已提到的所有三项内容（ellipsize，selected和singleLine）：
TextView tv = (TextView)findViewById(R.id.someTextView);
tv.setSelected(true);
tv.setEllipsize(TruncateAt.MARQUEE);
tv.setSingleLine(true):

Xml代码
<TextView
android:id="@+id/txtTicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_gravity="center_horizontal"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"

android:singleLine="true"
android:textColor="@android:color/white"
android:textSize="20sp"
android:textStyle="bold" >
</TextView>
爪哇
txtEventName.setSelected(true);
如果文字较小，则在文字
之前和之后添加空格txtEventName.setText("\t \t \t \t \t \t"+eventName+"\t \t \t \t \t \t");
答案 5 :(得分：8)
将这些参数放到TextView中 - 它的工作原理：D
android:singleLine="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:focusable="true"
android:focusableInTouchMode="true"
您还需要setSelected(true)：
my_TextView.setSelected(true);

我建议使用Webview如果要水平移动短字符串。 Main_Activity.java代码：`
WebView webView;
webView = (WebView)findViewById(R.id.web);
String summary = "<html><FONT color='#fdb728' FACE='courier'><marquee behavior='scroll' direction='left' scrollamount=10>"
+ "Hello Droid" + "</marquee></FONT></html>";
webView.loadData(summary, "text/html", "utf-8"); // Set focus to the textview
`
main_activity.xml代码：
<WebView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/web"
></WebView>
答案 7 :(得分：2)
除了droidgren识别的XML设置外，我的测试表明，如果要显示的文本比textview的宽度短，那么选取框根本不会滚动。可能的解决方案是将视图的宽度设置为小于文本长度的大小，或者将字符串连接到自身2或3次，中间可能有适当的空格，以便滚动看起来正常。
答案 8 :(得分：2)
在XML中添加以下代码
<TextView
android:text="Shops NearBy textdf fsdgsdgsdg dsgtsgsdgsdgsg"
android:id="@+id/txtEventName"
android:ellipsize="marquee"
android:marqueeRepeatLimit ="marquee_forever"
android:focusable="true"
android:focusableInTouchMode="true"
android:scrollHorizontally="true"
android:singleLine="true"/>
在Java中添加以下代码：
TextView txtEventName=(TextView)findViewById(R.id.txtEventName);
txtEventName.setSelected(true);

用它来设置Marque：
final TextView tx = (TextView) findViewById(R.id.textView1);
tx.setEllipsize(TruncateAt.MARQUEE);
tx.setSelected(true);
tx.setSingleLine(true);
tx.setText("Marquee needs only three things to make it run and these three things are mentioned above.");
您不需要将“ android：marqueeRepeatLimit =”marquee_forever “用于xml文件。即使没有这个，Marquee也能正常工作。
答案 10 :(得分：1)
在XML文件中，您需要在TextView中添加以下附加属性才能获得类似于字幕的功能：
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true"
在MainActivity.java文件中，您可以使用findViewById（）获取此TextView的引用，并且可以将以下属性设置为此TextView，使其看起来像一个选框文本：
setSelected(true);
这就是你所需要的一切。
答案 11 :(得分：1)
我已经尝试了以上所有，但对我来说它没有用。 当我添加
android:clickable="true"
然后它对我来说很完美。我不知道为什么。但我很乐意去做。
以下是我的完整答案。
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:singleLine="true"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:clickable="true"
答案 12 :(得分：0)
您可以使用TextView或自定义TextView。 后者是文本视图无法始终聚焦的时候。
首先，您可以使用TextView或自定义TextView作为布局.xml文件中的滚动文本视图，如下所示：
public class CustomTextView extends TextView {
public CustomTextView(Context context) {
super(context);
}
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
if(focused)
super.onFocusChanged(focused, direction, previouslyFocusedRect);
}
@Override
public void onWindowFocusChanged(boolean focused) {
if(focused)
super.onWindowFocusChanged(focused);
}
@Override
public boolean isFocused() {
return true;
}
}
注意：在上面的代码片段中，com.example.myapplication是一个示例包名称，应该用您自己的包名替换。
然后，在使用CustomTextView的情况下，您应该定义CustomTextView类：
here is my code:
public class AbstractActivity extends AppCompatActivity implements View.OnClickListener{
private String[] mPlanetTitles;
private LinearLayout mDrawerList;
protected DrawerLayout mDrawerLayout;
protected ActionBarDrawerToggle mDrawerToggle;

根据上述答案，您无法设置速度或灵活地自定义文本视图功能。要拥有自己的滚动速度和灵活性来自定义选取框属性，请使用以下命令：
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:fadingEdge="horizontal"
android:lines="1"
android:id="@+id/myTextView"
android:padding="4dp"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="Simple application that shows how to use marquee, with a long text" />
在您的活动中：
private void setTranslation() {
TranslateAnimation tanim = new TranslateAnimation(
TranslateAnimation.ABSOLUTE, 1.0f * screenWidth,
TranslateAnimation.ABSOLUTE, -1.0f * screenWidth,
TranslateAnimation.ABSOLUTE, 0.0f,
TranslateAnimation.ABSOLUTE, 0.0f);
tanim.setDuration(1000);//set the duration
tanim.setInterpolator(new LinearInterpolator());
tanim.setRepeatCount(Animation.INFINITE);
tanim.setRepeatMode(Animation.ABSOLUTE);
textView.startAnimation(tanim);
}

答案 15 :(得分：0)
这是我的xml customTextView对象，您可以在其中使用TextView替换Tag。
<com.wedoapps.crickethisabkitab.utils.view.montserrat.CustomTextView
android:id="@+id/lblRateUsPlayStore"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/_10sdp"
android:layout_marginBottom="@dimen/_10sdp"
android:layout_marginStart="@dimen/_5sdp"
android:layout_marginEnd="@dimen/_5sdp"
android:text="@string/please_rate_us_5_star_on_play_store"
android:textAllCaps="false"
android:textColor="@color/green"
android:textSize="@dimen/_25ssp"
android:textStyle="bold"
android:visibility="visible"
android:linksClickable="true"
android:autoLink="web|phone"/>
这是我的Java文件代码。我已经在服务器上设置了我的html文本，只是替换了textview对象上的文本。如果此textview上的任何链接可以打开移动设备或webBrowser，则我将这段代码放在带有可点击的Marquee标记中。
CustomTextView lblRateUsPlayStore = findViewById(R.id.lblRateUsPlayStore);
lblRateUsPlayStore.setMovementMethod(LinkMovementMethod.getInstance());
lblRateUsPlayStore.setText( Html.fromHtml(documentSnapshot.getString("DisplayText")));
TextViewCompat.setAutoSizeTextTypeUniformWithConfiguration(lblRateUsPlayStore, 12, 20, 2, 1);
lblRateUsPlayStore.setEllipsize(TextUtils.TruncateAt.MARQUEE);
// Set marquee repeat limit (unlimited)
lblRateUsPlayStore.setMarqueeRepeatLimit(-1);
lblRateUsPlayStore.setHorizontallyScrolling(true);
lblRateUsPlayStore.setSelected(true);
lblRateUsPlayStore.setLinksClickable(true);
lblRateUsPlayStore.setFocusableInTouchMode(true);
lblRateUsPlayStore.setFocusable(true);
答案 16 :(得分：0)
很多答案正确地表明需要呼叫textView.setSelected(true)。但是，如果更喜欢仅通过 XML 这样做，则一种选择是在与Binding Adapters一起使用时使用Data Binding。
因此，只需创建一个类似于以下内容的新适配器即可：
@BindingAdapter("app:autoStartMarquee")
fun setAutoStartMarquee(textView: TextView, autoStartMarquee: Boolean) {
textView.isSelected = autoStartMarquee
}
然后，您可以简单地在XML中使用它，如下所示：
...
<TextView
...
android:ellipsize="marquee"
android:singleLine="true"
app:autoStartMarquee="@{true}"/>
...
不再需要从代码中调用它。
答案 17 :(得分：0)
您可以使用
android:ellipsize="marquee"
使用您的文本视图。
但是请记住将重点放在所需的文本视图上。
答案 18 :(得分：0)
用于以编程方式设置选取框
TextView textView = (TextView) this.findViewById(R.id.textview_marquee);
textView.setEllipsize(TruncateAt.MARQUEE);
textView.setMarqueeRepeatLimit(-1);
textView.setText("General Information... general information... General Information");
textView.setSelected(true);
textView.setSingleLine(true);
