我已经将我的Edittext数据以HTML格式存储在DB中。我正在使用HTML.fromHTML()。
在HTML文本视图中显示相同的数据。现在,我想将此HTML字符串作为图像共享。我正在尝试以下方法。
// storing below value in DB
String Notes= Html.toHtml(notes_content.getText());
//Then through select query i am fetching data as a string.
String notescontent;
Cursor data = mDatabaseHelper.getData();
listData = new ArrayList<>();
while (data.moveToNext()) {
notescontent= data.getString(1);
}
String content=Html.fromHtml(notescontent).toString();
System.out.println(">>>>>>>>>>>>>>>>>> content >>>>>>>>>>> "+content);
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
paint.setTextSize(20f);
paint.setColor(Color.WHITE);
paint.setTextAlign(Paint.Align.LEFT);
float baseline = -paint.ascent(); // ascent() is negative
int width = (int) (paint.measureText(content) + 0.5f); // round
int height = (int) (baseline + paint.descent() + 0.5f);
Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888); //use ARGB_8888 for better quality
Canvas canvas = new Canvas(bmp);
canvas.drawText(content, 0, baseline, paint);
File cachePath = new File(this.getCacheDir(), "images");
cachePath.mkdirs(); // don't forget to make the directory
FileOutputStream stream = new FileOutputStream(cachePath + "/Notes.png"); // overwrites this image every time
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
stream.close();
File imagePath = new File(this.getCacheDir(), "images");
File newFile = new File(imagePath, "Smart_Notes.png");
Uri contentUri = FileProvider.getUriForFile(this, "com.note.fileprovider", newFile);
if (contentUri != null) {
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); // temp permission for receiving app to read this file
shareIntent.setDataAndType(contentUri, getContentResolver().getType(contentUri));
shareIntent.putExtra(Intent.EXTRA_STREAM, contentUri);
startActivity(Intent.createChooser(shareIntent, "Choose an app"));
图像已成功存储在缓存目录中,我也能够成功共享。
问题:
我的文本为HTML格式,所以我将其转换为字符串String content = Html.fromHtml(notescontent).toString();并共享为图像,但文本并未按原样显示。
HTML格式(粗体,斜体)不再出现。此外,文本格式不正确,文本在图像中为单行。
在从html转换之前,请在notescontent(我从数据库中获取的字符串值)下面找到
I/System.out: >>>>>>>>>>>>>>>>>> content >>>>>>>>>>> <p dir="ltr">testing date and time ? tested by <b>ajinkya kadam</b>.<br></p>
<p dir="ltr">this is a test data for <b><i>testing purpose</i></b><br>
</p>
请从HTML转换后,在notescontent下方找到String content = Html.fromHtml(notescontent).toString();] >>
I/System.out: >>>>>>>>>>>>>>>>>> content >>>>>>>>>>> testing date and time ? tested by ajinkya kadam. this is a test data for testing purpose
有人可以在上面帮助我吗?我希望文本应该以带有样式和换行符的图像形式出现。
非常感谢。
我已经将我的Edittext数据以HTML格式存储在DB中。我正在使用HTML.fromHTML()以HTML格式在textview中显示相同的数据。现在,我想将此HTML字符串作为图像共享。我正在尝试以下...
如下使用TextPaint
和StaticLayout
来获得所需的格式:
