TextView标牌与数字时钟

Question

当我使用Digital clock和textview marquee时，textview marquee就不能工作--如果我移除数字时钟，它就会完美地工作。

 TextView tv = new TextView(this);

    tv.setLayoutParams(paramsSong);     
    tv.setEllipsize(TruncateAt.MARQUEE);
    tv.setFocusableInTouchMode(true);
    tv.setFreezesText(true);
    tv.setSingleLine(true);
    tv.setMarqueeRepeatLimit(-1);
    tv.setText("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa");
    tv.setSelected(true);
            rl.addView(tv);

    DigitalClock dg = new DigitalClock(this);
            rl.addView(dg);

/*if I remove digital clock then it works*/

我能不能同时使用这两种方法，或者有什么解决办法？

Answer 1

是的，你可以用这些，但首先要改正你的错误

1.您要添加rl.addView(tv); 2次视图

2. set Height和Width of DigitalClock

试试下面的代码，这些代码对我很好

   TextView tv = new TextView(this);
    rl.addView(tv);// Here is Your Mistake ! Remove it 
    tv.setLayoutParams(paramsSong);     
    tv.setEllipsize(TruncateAt.MARQUEE);
    tv.setFocusableInTouchMode(true);
    tv.setFreezesText(true);
    tv.setSingleLine(true);
    tv.setMarqueeRepeatLimit(-1);
    tv.setText("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa");
    tv.setSelected(true);
            rl.addView(tv);// Adding view Here is Absolutely Right ! 

    DigitalClock dg = new DigitalClock(this);
    dg.setHeight(setHeightHere);
    dg.setWidth(setWidthHere);
            rl.addView(dg);

PS. DigitalClock class was deprecated in API level 17

It is recommended you use TextClock instead.
