我们可以在警报对话框中使用资产html文件吗？

Question

目前我使用的字符串，以显示警报对话框文本，有没有办法资产使用HTML文件的情况下直接使用的布局和显示警告对话框这样的代码

private void About() { 
    AlertDialog alertDialog = new AlertDialog.Builder(this).create(); 
    alertDialog.setTitle(getString(R.string.about)); 
    alertDialog.setMessage(getString(R.stringabout)); 
    alertDialog.setIcon(R.drawable.ic_launcher); 
    alertDialog.setButton(DialogInterface.BUTTON_NEUTRAL, 
      getString(R.string.lbl_dialog_close), 
      new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int which) { 
        close 
       } 
      }); 
    alertDialog.show(); 
}

尝试这种方式，

try { 
      InputStream is = getAssets().open("yourhtmlfile.txt"); 

      // We guarantee that the available method returns the total 
      // size of the asset... of course, this does mean that a single 
      // asset can't be more than 2 gigs. 
      int size = is.available(); 

      // Read the entire asset into a local byte buffer. 
      byte[] buffer = new byte[size]; 
      is.read(buffer); 
      is.close(); 

      // Convert the buffer into a string. 
      String text = new String(buffer); 

      // Finally stick the string into the text view. 
      TextView tv = (TextView)findViewById(R.id.text); 
      tv.setText(text); 
     } catch (IOException e) { 
      // Should never happen! 
      throw new RuntimeException(e); 
     }
