を使用して、画像を含む HTML のブロックを TextView に読み込もうとしています
URLImageParser p = new URLImageParser(articleBody, this);
Spanned htmlSpan = Html.fromHtml(parsedString, p, null);
ちなみに、parsedString は HTML です。とにかく、それはロードされますが、画像にはそれらが収まるスペースが作成されていないため、その上のテキストに重なってしまいます. ここに私の URLImageParser ファイルがあります:
public class URLImageParser implements Html.ImageGetter {
Context c;
View container;
/***
* Construct the URLImageParser which will execute AsyncTask and refresh the container
* @param t
* @param c
*/
public URLImageParser(View t, Context c) {
this.c = c;
this.container = t;
}
public Drawable getDrawable(String source) {
URLDrawable urlDrawable = new URLDrawable();
// get the actual source
ImageGetterAsyncTask asyncTask =
new ImageGetterAsyncTask( urlDrawable);
asyncTask.execute(source);
// return reference to URLDrawable where I will change with actual image from
// the src tag
return urlDrawable;
}
public class ImageGetterAsyncTask extends AsyncTask<String, Void, Drawable> {
URLDrawable urlDrawable;
public ImageGetterAsyncTask(URLDrawable d) {
this.urlDrawable = d;
}
@Override
protected Drawable doInBackground(String... params) {
String source = params[0];
return fetchDrawable(source);
}
@Override
protected void onPostExecute(Drawable result) {
// set the correct bound according to the result from HTTP call
Log.d("height",""+result.getIntrinsicHeight());
Log.d("width",""+result.getIntrinsicWidth());
urlDrawable.setBounds(0, 0, 0+result.getIntrinsicWidth(), 0+result.getIntrinsicHeight());
// change the reference of the current drawable to the result
// from the HTTP call
urlDrawable.drawable = result;
// redraw the image by invalidating the container
URLImageParser.this.container.invalidate();
}
/***
* Get the Drawable from URL
* @param urlString
* @return
*/
public Drawable fetchDrawable(String urlString) {
try {
URL aURL = new URL(urlString);
final URLConnection conn = aURL.openConnection();
conn.connect();
final BufferedInputStream bis = new BufferedInputStream(conn.getInputStream());
final Bitmap bm = BitmapFactory.decodeStream(bis);
Drawable drawable = new BitmapDrawable(bm);
drawable.setBounds(0,0,bm.getWidth(),bm.getHeight());
return drawable;
} catch (Exception e) {
return null;
}
}
}
}
何か案は?ありがとうございます。
