java - 如何从assets文件夹中共享htm文本文件？

Question

我已经使用下面的代码很长时间了，直到今天我尝试从 Assets 文件夹加载一些 html 文本文件。但不幸的是，共享 Intent 并没有奏效。因为我以前是用EXTRA_TEXT来声明的。现在我从 private static Final String URL="file:///android_asset/html_files/dancerkate.html";

读取了我的文件

请帮我更改此代码。这样它就可以共享 dancerkate.html 中的文本谢谢!

        switch (item.getItemId()){

            case R.id.share_button:
                //share Copied Text characters via other apps button
                Intent sendIntent = new Intent();
                sendIntent.setAction(Intent.ACTION_SEND);
                sendIntent.putExtra(Intent.EXTRA_TEXT, textView.getText().toString() + "Get App here: https://play.google.com/store/apps/details?id=com.joseph.workerbender");
                sendIntent.setType("text/plain");
                Intent.createChooser(sendIntent, "Share via");
                startActivity(sendIntent);

        }

        return super.onOptionsItemSelected(item);

首先，当intentType为text时，无法使用intent发送文件

sendIntent.setType("text/plain");

您可以读取 .html 文件并获取该文件内的文本并通过共享发送

private String getTextFromAssets(String fileName){
    try {
        final int bufferSize = 1024;
        final char[] buffer = new char[bufferSize];

        InputStream inputStream = getResources().getAssets().open(fileName);

        final StringBuilder out = new StringBuilder();
        Reader in = new InputStreamReader(inputStream, Charset.forName("UTF-8"));
        int charsRead;
        while((charsRead = in.read(buffer, 0, buffer.length)) > 0) {
            out.append(buffer, 0, charsRead);
        }
        Log.d("HtmlText", out.toString());
        return out.toString();
    } catch (IOException e) {
        Log.e("HtmlText", "HTML Read Error: "+e.toString());
    }
    return "";
}

现在从代码中调用该方法

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, getTextFromAssets("dancerkate.html"));
sendIntent.setType("text/plain");
Intent.createChooser(sendIntent, "Share via");
startActivity(sendIntent);
