TextView字幕和数字时钟

Question

当我使用Digital clock和textview marquee时，textview marquee不工作——如果我去掉数字时钟，它就可以完美工作。

 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*/

我可以不同时使用两者吗？或者有什么解决方案吗？

Answer 1

是的，你可以使用这些，但首先要纠正你的错误

1.您正在添加视图rl.addView(tv); 2倍

2.设置DigitalClock 的Height和Width

试试下面的代码，这对我来说很好

   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);

It is recommended you use TextClock instead.
