在-90度旋转TextView的总 [英] Rotate total Textview in -90 degrees

问题描述

我想设置我的TextView的在-90度意味着我哈弗显示它这个样子！我ahve显示在单一的线性布局8 textviews。我能够旋转，但我可以看到只有一个textview.Please任何一个可以帮助我做一些例子。

先谢谢了。

 公共类AngledTextView扩展的TextView
{       公共AngledTextView（上下文的背景下，ATTRS的AttributeSet）
       {
          超（背景下，ATTRS）;
       }       @覆盖
       保护无效的onDraw（帆布油画）
       {//保存当前矩阵
         canvas.save（）;
         //为中心旋转由此看来
         canvas.rotate（270，this.getWidth（）/ 2，this.getHeight（）/ 2）;
         // 画出来
         super.onDraw（画布）;
         //还原到previous矩阵
         canvas.restore（）;
        }
 }
 

解决方案

对于垂直的TextView我用下面的code和它完美工作。

 公共类VerticleTextView扩展的TextView {最终布尔自上而下;
公共VerticleTextView（上下文的背景下，ATTRS的AttributeSet）{
    超（背景下，ATTRS）;
    最终诠释比重= getGravity（）;
    如果（Gravity.isVertical（重力）及及（重力＆放大器; Gravity.VERTICAL_GRAVITY_MASK）== Gravity.BOTTOM）{
       setGravity（（重力和放大器; Gravity.HORIZONTAL_GRAVITY_MASK）| Gravity.TOP）;
       自上而下= FALSE;
    }其他
       自上而下= TRUE;
 } @覆盖
 保护无效onMeasure（INT widthMeasureSpec，诠释heightMeasureSpec）{
    super.onMeasure（heightMeasureSpec，widthMeasureSpec）;
    setMeasuredDimension（getMeasuredHeight（），getMeasuredWidth（））;
 } @覆盖
 保护无效的onDraw（帆布油画）{
    TextPaint textPaint = getPaint（）;
    textPaint.setColor（getCurrentTextColor（））;
    textPaint.drawableState = getDrawableState（）;    canvas.save（）;    如果（自上而下）{
       canvas.translate（的getWidth（），0）;
       canvas.rotate（90）;
    }其他{
       canvas.translate（0，的getHeight（））;
       canvas.rotate（-90）;
    }
    canvas.translate（getCompoundPaddingLeft（），getExtendedPaddingTop（））;    。getLayout（）画（油画）;
    canvas.restore（）;
}
}
 

I want to set my textview in -90 degrees means i haver to show it like this! i ahve to show 8 textviews in single linear layout. i am able to rotate but i can see only one textview.Please can any one help me with some example.

Thanks in advance.

public class AngledTextView extends TextView
{ 

       public AngledTextView(Context context, AttributeSet attrs) 
       { 
          super(context, attrs); 
       } 

       @Override 
       protected void onDraw(Canvas canvas) 
       { // Save the current matrix 
         canvas.save(); 
         // Rotate this View at its center 
         canvas.rotate(270,this.getWidth()/2, this.getHeight() /2); 
         // Draw it 
         super.onDraw(canvas); 
         // Restore to the previous matrix 
         canvas.restore(); 
        } 
 } 

解决方案

for a vertical TextView i used the following code and it worked perfectly.

public class VerticleTextView extends TextView {

final boolean topDown;
public VerticleTextView(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 void onDraw(Canvas canvas){
    TextPaint textPaint = getPaint(); 
    textPaint.setColor(getCurrentTextColor());
    textPaint.drawableState = getDrawableState();

    canvas.save();

    if(topDown){
       canvas.translate(getWidth(), 0);
       canvas.rotate(90);
    }else {
       canvas.translate(0, getHeight());
       canvas.rotate(-90);
    }


    canvas.translate(getCompoundPaddingLeft(), getExtendedPaddingTop());

    getLayout().draw(canvas);
    canvas.restore();
}
}
