How to use Android setTranslation ? (or another way to move a textview ?)
提问by user1948708
I want to start to make a "spirit level" app (not sure of this word, the tool to make sure the surface you put it on is even(straight)) for school. For now I just want to move textviews then I'll had the sensor listener to do it automatically then i'll turn them to images, etc..
我想开始为学校制作一个“精神层面”的应用程序（不确定这个词，确保你把它放在表面上的工具是均匀的（直的））。现在我只想移动文本视图，然后我会让传感器监听器自动执行它，然后我会将它们转换为图像等。
Anyway, I can't move the textView in the screen!
无论如何，我无法在屏幕中移动textView！
I found a method in view, called setTranslationX and setTranslationY who seem to do exactly what I want, so I tried to use them this way:
我在视图中找到了一个名为 setTranslationX 和 setTranslationY 的方法，它们似乎完全符合我的要求，所以我尝试以这种方式使用它们：
super.onCreate(savedInstanceState);
float nombre=100;
setContentView(R.layout.activity_main);
TextView H = (TextView) findViewById(R.id.Champ_H);
H.setTranslationX(nombre);
To just move a textView to the right.
只需将 textView 向右移动。
But I've got this message for the last line:
但我在最后一行收到了这条消息：
The method setTranslationX(float) is undefined for the type TextView
未定义 TextView 类型的 setTranslationX(float) 方法
The problem is, yes, it is, I looked the documentation, this method exists and takes a float as a parameter. I've of course imported android.view.View which is supposed to contain it, but that won't work. I've also tried to use setLeft which does a similar thing but the same problem occurs. It seems that every method what would allow me to move a textView, eclipse won't let me use them.
问题是，是的，是的，我查看了文档，此方法存在并采用浮点数作为参数。我当然已经导入了应该包含它的 android.view.View ，但这不起作用。我也尝试使用 setLeft 做类似的事情，但发生了同样的问题。似乎每种允许我移动 textView 的方法，eclipse 都不会让我使用它们。
Does anybody know why? Or know an other way to move a TextView?
有人知道为什么吗？或者知道另一种移动 TextView 的方法？

You may need to specify the unit to translate. try:
您可能需要指定要翻译的单位。尝试：
H.setTranslationX(100px);
