Answer 1

希望对你有帮助...

public void selectAndCopyText() {
     try {
         Method m = WebView.class.getMethod("emulateShiftHeld", Boolean.TYPE); 
            m.invoke(BookView.mWebView, false); 
        } catch (Exception e) {
            e.printStackTrace();
            // fallback
            KeyEvent shiftPressEvent = new KeyEvent(0,0,
                 KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_SHIFT_LEFT,0,0);
            shiftPressEvent.dispatch(this);
        }

}

覆盖触摸事件

private void emulateShiftHeld(WebView view)
    {
        try
        {
            KeyEvent shiftPressEvent = new KeyEvent(0, 0, KeyEvent.ACTION_DOWN,
                                                    KeyEvent.KEYCODE_SHIFT_LEFT, 0, 0);
            shiftPressEvent.dispatch(view);
            Toast.makeText(this, "select_text_now", Toast.LENGTH_SHORT).show();
        }
        catch (Exception e)
        {
            Log.e("dd", "Exception in emulateShiftHeld()", e);
        }
    }

根据某人博客的这个网站说“在Android 3.0及更高版本中默认情况下可以使用WebView中的复制功能”，并且可能这些信息可能会有所帮助，Android：如何从webview中选择文本
