3. drawableleft.setBounds(0, 0, drawableleft.getMinimumWidth(),  
4.         drawableleft.getMinimumHeight());  
5.   
6. txt_bind_qq.setCompoundDrawables(drawableleft, null,  
7.         TextToDrawable(R.string.bound), null);  

把字符串转化为drawable：

[java]  view plain  copy

 

1. public Drawable TextToDrawable(int id) {  
2.     Bitmap bitmap = Bitmap.createBitmap(200, 250, Config.ARGB_8888);

5.     paint.setTextSize(65);  
6.     paint.setTextAlign(Align.LEFT);  
7.     paint.setColor(Color.GRAY);  
8.     String s = getResources().getString(id);  
9.     FontMetrics fm = paint.getFontMetrics();  
10.     canvas.drawText(s, 0, 145 + fm.top - fm.ascent, paint);  
11.     canvas.save();  
12.     Drawable drawableright = new BitmapDrawable(bitmap);  
13.     drawableright.setBounds(0, 0, drawableright.getMinimumWidth(),  
14.             drawableright.getMinimumHeight());  
15.     return drawableright;
