请帮帮我。非常感谢。

    public void onClick(View view) {

        bitmapDrawable = (BitmapDrawable) holder.imageView.getDrawable();// get the from imageview or use your drawable from drawable folder
        bitmap1 = bitmapDrawable.getBitmap();
        String imgBitmapPath= MediaStore.Images.Media.insertImage(context.getContentResolver(),
                bitmap1,"title",null);
        Uri imgBitmapUri=Uri.parse(imgBitmapPath);
        String shareText=paheliItem.getTitle();
        Intent shareIntent=new Intent(Intent.ACTION_SEND);
        shareIntent.setType("*/*");
        shareIntent.putExtra(Intent.EXTRA_STREAM,imgBitmapUri);
        shareIntent.putExtra(Intent.EXTRA_TEXT, shareText);
        context.startActivity(Intent.createChooser(shareIntent,"Share Wallpaper using"));

查看下面的代码：

private void drawTextOnBitmap(Bitmap bmp, String text, int x, int y, int textColor) {
        Canvas canvas = new Canvas(bmp);

        Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
        paint.setColor(textColor);
        // draw text
        canvas.drawText(text, x, y, paint);
    }


holder.shareBtn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

        bitmapDrawable = (BitmapDrawable) holder.imageView.getDrawable();// get the from imageview or use your drawable from drawable folder
        // draw text on bitmap
        Bitmap bitmap1 = bitmapDrawable.getBitmap();
        drawTextOnBitmap(bitmap1, "YOUR TEXT", 0, 15, Color.RED);


        String imgBitmapPath= MediaStore.Images.Media.insertImage(context.getContentResolver(),
                bitmap1,"title",null);
        Uri imgBitmapUri=Uri.parse(imgBitmapPath);
        String shareText=paheliItem.getTitle();
        Intent shareIntent=new Intent(Intent.ACTION_SEND);
        shareIntent.setType("*/*");
        shareIntent.putExtra(Intent.EXTRA_STREAM,imgBitmapUri);
        shareIntent.putExtra(Intent.EXTRA_TEXT, shareText);
        context.startActivity(Intent.createChooser(shareIntent,"Share Wallpaper using"));

    }
});
