android旋转按钮文字90度

标签: android xml button

我的应用程序中有一个充满按钮的屏幕,我需要有三个特定的按钮才能转90度所以他们的文字会被翻转我尝试使用

      sed s/\([0-9]\)\.,/\1./g' "$f" > "$f".new && /bin/mv "$f".new "$f"

它修复了我的文字方向问题,但它使得按钮太小(按钮保持其宽度尺寸) 我需要它看起来像这样 enter image description here

这三个按钮我需要更改(说明1st12 2st12和3st12的按钮):

android:rotation="90"

任何帮助都将非常感谢

您可以自定义TextView:

public class VerticalTextView extends TextView{
   final boolean topDown;

   public VerticalTextView(Context context, AttributeSet attrs){
      super(context, attrs);
      final int gravity = getGravity();
      if(Gravity.isVertical(gravity) && (gravity&Gravity.VERTICAL_GRAVITY_MASK) == Gravity.BOTTOM) {
         setGravity((gravity&Gravity.HORIZONTAL_GRAVITY_MASK) | Gravity.TOP);
         topDown = false;
      }else
         topDown = true;
   }

   @Override
   protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
      super.onMeasure(heightMeasureSpec, widthMeasureSpec);
      setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth());
   }

   @Override
   protected boolean setFrame(int l, int t, int r, int b){
      return super.setFrame(l, t, l+(b-t), t+(r-l));
   }

   @Override
   public void draw(Canvas canvas){
      if(topDown){
         canvas.translate(getHeight(), 0);
         canvas.rotate(90);
      }else {
         canvas.translate(0, getWidth());
         canvas.rotate(-90);
      }
      canvas.clipRect(0, 0, getWidth(), getHeight(), android.graphics.Region.Op.REPLACE);
      super.draw(canvas);
   }
}
