java - Android HTML.ImageGetter 图片调整大小

Question

我有一个加载 HTML 内容的 TextView(它也有 img 标签)。我的问题是有些图片太大，导致应用程序崩溃。有什么方法可以使所有图像的大小相同吗？

我的代码示例:

            String EntireStire = "<b>" + mItem.title + " </b> <br> <img src='"
                + mItem.photo + "' > " + " <br><small>" + mItem.description
                + " <br> " + mItem.content + "</small>";

        noteView.setText(Html.fromHtml(EntireStire, new MyImageGetter(),
                null));
        noteView.setMovementMethod(LinkMovementMethod.getInstance());
    }

    return rootView;
}

private class MyImageGetter implements Html.ImageGetter {

    @Override
    public Drawable getDrawable(String arg0) {
        Bitmap bitmap;
        try {
            bitmap = BitmapFactory.decodeStream(
                    (InputStream) new URL(arg0).getContent(), null, null);
            @SuppressWarnings("deprecation")
            Drawable drawable = new BitmapDrawable(bitmap);
            drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),
                    drawable.getIntrinsicHeight());
            return drawable;
        } catch (Exception e) {
            Drawable d = getResources().getDrawable(R.drawable.ic_launcher);
            d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
            return d;
        }
    }
}

改用这段代码，它会调整你的图片大小

private class MyImageGetter implements Html.ImageGetter {
    private final Context context;

    public MyImageGetter (Context context){
        this.context = context;
    }

    @Override
    public Drawable getDrawable(String source) {
        int path = context.getResources().getIdentifier(source, "drawable",
                BuildConfig.APPLICATION_ID);
            Drawable drawable = context.getResources().getDrawable(path);
            Display display = getWindowManager().getDefaultDisplay();
            Point size = new Point();
            display.getSize(size);
            int widthD = size.x;
            int heightD = size.y;
            drawable.setBounds(0, 0, widthD, (widthD* drawable.getIntrinsicHeight()/ drawable.getIntrinsicWidth()));
            return drawable;

    }
}
