如何在Android的TextView的画在画布上..？

How to Draw TextView on Canvas in android..?

我们有 Canvas.DrawBitmap（）， Canvas.drawText（）。我们有在画布这需要的TextView作为一个参数或显示TextView的画布？任何其他方法的任何方法

We have Canvas.DrawBitmap(), Canvas.drawText(). Do we have any Method in Canvas which takes TextView as a parameter or any other method to display TextView on Canvas?

其实，我在TextView中一个字母，我要做出的字母是在画布上绘制。

Actually, I have a alphabet in TextView and I have to make drawing on that alphabet which is in canvas.

请说明什么....谢谢您的合作。

Please suggest anything....Thanks for your cooperation

推荐答案

您不能得出一个TextView直接，但你可以把它放在一个布局和绘制布局。事情是这样的：

You can't draw a Textview directly, but you can put it in a layout and draw the layout. Something like this:

LinearLayout layout = new LinearLayout(context);

TextView textView = new TextView(context); 
textView.setVisibility(View.VISIBLE);
textView.setText("Hello world");
layout.addView(textView);

layout.measure(canvas.getWidth(), canvas.getHeight());
layout.layout(0, 0, canvas.getWidth(), canvas.getHeight());

// To place the text view somewhere specific:
//canvas.translate(0, 0);

layout.draw(canvas);
