我可以将所有文本视图设置为字幕吗？

Question

我有6个文本视图，我希望它们同时字幕

 <TextView
    android:ellipsize="marquee"
    android:focusable="true"
    android:focusableInTouchMode="true"/>

 <TextView
    android:ellipsize="marquee"
    android:focusable="true"
    android:focusableInTouchMode="true">

可能吗？

码

TextView txt2 = (TextView)findViewById(r.id.TextView2)
txt2.setSelected(true);

但它总是使我的应用程序崩溃

试试这个：-我希望它能帮到你..... :)

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:id="@+id/TextView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ellipsize="marquee"
        android:marqueeRepeatLimit="marquee_forever"
        android:padding="5dip"
        android:scrollHorizontally="true"
        android:singleLine="true"
        android:text="Hello World" />

    <TextView
        android:id="@+id/TextView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/TextView1"
        android:ellipsize="marquee"
        android:marqueeRepeatLimit="marquee_forever"
        android:padding="5dip"
        android:scrollHorizontally="true"
        android:singleLine="true"
        android:text="Testing!!!" />

</RelativeLayout>

在您的活动中尝试一下

    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
 Animation animationToLeft = new TranslateAnimation(400, -400, 0, 0);
        animationToLeft.setDuration(12000); 
        animationToLeft.setRepeatMode(Animation.RESTART);
        animationToLeft.setRepeatCount(Animation.INFINITE);

        Animation animationToRight = new TranslateAnimation(-400,400, 0, 0);
        animationToRight.setDuration(12000); 
        animationToRight.setRepeatMode(Animation.RESTART);
        animationToRight.setRepeatCount(Animation.INFINITE);

        TextView tv = (TextView) findViewById(R.id.TextView02);
        TextView tv1 = (TextView) findViewById(R.id.TextView03);

        tv.setAnimation(animationToLeft);
        tv1.setAnimation(animationToRight);


        String textLeft = "Really Long Scrolling Text Goes Here.... ..... ............ .... ....";
        String textRight = "Testing";

        tv.setText(textLeft);
        tv1.setText(textRight);
}

基于android SDK 2.3.3的测试

1. TextViews的布局如下：

    <TextView android:id="@+id/txt1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:ellipsize="marquee" android:marqueeRepeatLimit="marquee_forever" android:singleLine="true" android:text="I have 6 textviews and I want them to marquee all at the same time" /> 

2. 为每个textview设置属性：

    TextView txt1 = (TextView)this.findViewById(R.id.txt1); txt1.setSelected(true); txt1.setTextColor(Color.WHITE); ... ...
