从EditText及其内容创建位图图像

EditText editText = findViewById(R.id.edit_text);
Bitmap bitmap = Bitmap.createBitmap(editText.getWidth(), editText.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
editText.draw(canvas);

TextView textView = findViewById(R.id.text_view);
Bitmap bitmap = Bitmap.createBitmap(textView.getWidth(), textView.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
textView.draw(canvas);

Paint paint = new Paint();
paint.setColor(Color.BLACK);
paint.setTextSize(24);
paint.setAntiAlias(true);

String text = "Hello, world!";
int textWidth = (int) paint.measureText(text);
int textHeight = (int) (paint.descent() - paint.ascent());

Bitmap bitmap = Bitmap.createBitmap(textWidth, textHeight, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
canvas.drawText(text, 0, textHeight - paint.descent(), paint);

File file = new File(Environment.getExternalStorageDirectory(), "image.png");
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.close();
