将EditText和ImageView合并为单个图像（位图）？

Question

我在 ImageView 上放置了 EditText 和 ImageView 。我希望 EditText 上的书面文字是 ImageView 的一部分，作为单个图像（位图），因为它在写入时显示。我尝试过使用 canvas.drawText(...) ，但在撰写时却看不清楚。

Answer 1

以下是我解决这个问题的方法。如果我想要的图像是：

然后解决方案将是：

    /**
 * Merging Two Images into One Image.
 * @param baseImage Bitmap as Lower Image , Image to be appeared underneath.
 * @param headerImage Bitmap as Upper Image, Image to be appeared upon the lower image.
 * @return finalImage Bitmap as bytes having both images merged.
 */
public static byte[] mergeImages(Bitmap baseImage, Bitmap headerImage, Bitmap footerImage ) {
    Bitmap finalImage = Bitmap.createBitmap(baseImage.getWidth(), baseImage.getHeight(), baseImage.getConfig());
    Canvas canvas = new Canvas(finalImage);
    canvas.drawBitmap(baseImage, new Matrix(), null);

    if(headerImage != null){
        canvas.drawBitmap(headerImage, new Matrix(), null);
    }


    if(footerImage != null){
        Matrix matrix = new Matrix();
        matrix.setTranslate(0, baseImage.getHeight() - footerImage.getHeight());
        canvas.drawBitmap(footerImage, matrix, null);
    }


    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    finalImage.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] bytes = stream.toByteArray();

    return bytes;
}

一旦我做了类似的东西，你就是在努力。我使用Textview来做到这一点。我分别设置了它的背景资源和文本。

dat <- data.frame(one="\r\n Something", two="\n\n\n another one"
