用控件当画笔获得bitmap代码记录

int width = 1000;
int height = 1000;
TextView textView = new TextView(context);
Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);
Canvas canvas = new Canvas(bitmap);
textView.setText(“123”);
textView.setBackgroundColor(Color.YELLOW);
textView.setGravity(Gravity.CENTER);
textView.layout(0, 0, width, height);
textView.measure(View.MeasureSpec.makeMeasureSpec(width, View.MeasureSpec.EXACTLY),
View.MeasureSpec.makeMeasureSpec(height, View.MeasureSpec.EXACTLY));
textView.draw(canvas);
