是否可以在android的textview中垂直书写? [英] Is it possible to write vertically in a textview in android?

问题描述

假设您有一个普通的 TextView，其中写有Stackoverflow"，是否可以将 TextView 旋转 -90°，使 S 位于屏幕底部，W 位于屏幕顶部?当然，我可以将我的文本写成图像，旋转它并以这种方式使用它，但我现在对文本感兴趣.谢谢.

Let's say you have a normal TextView, with "Stackoverflow" written in it, Is it possible to rotate the TextView by -90°, to have the S at the bottom and the W at the top of the screen? Of course I could write my text as an image, rotate it and use it that way, but I am interested in the text right now. Thanks.

推荐答案

你可以像平常一样设置你的textview

You can set your textview as you would normally do

例如:

 <TextView android:id="@+id/txtview"
    android:layout_height="fill_parent"
    android:layout_width="wrap_content" />

并在您的活动中编写一个函数

and write a function in your activity to

• 反转文本中的字符
• 在每个字符后插入

• reverse the characters in your text
• insert after every characters

然后将文本设置到TextView.

and then set the text to the TextView.

如果您不想插入 ，则必须设置 android:layout_width 的大小并调整字体大小，不要让 2 个字符适合同一行，不截断

If you dont want to insert the , you will have to set the size of android:layout_width and play with font size not to have 2 characters fitting on the same line and no truncation

编辑如果我理解正确的话，你可以通过动画得到你想要的.

Edit If I have understood you correctly, you can get what you want by using animation.

例如

在res/anim/myanim.xml下:

<rotate  xmlns:android="http://schemas.android.com/apk/res/android"
           android:fromDegrees="0" 
           android:toDegrees="-90"
           android:pivotX="50%"
           android:duration="0" />

您必须使用此文件来定义您希望放置文本视图的位置.

You will have to play with this file to define where you want your text view to be placed.

在你的活动中:

  TextView t = (TextView)findViewById(R.id.txtview);
  String txt = "Stackoverflow";         
  t.setText(txt);

  RotateAnimation ranim = (RotateAnimation)AnimationUtils.loadAnimation(this, R.anim.myanim);
  ranim.setFillAfter(true); //For the textview to remain at the same place after the rotation
  t.setAnimation(ranim);
