Question

我正在使用getText()和getEditableText()中的修改在本机android应用程序中设置自定义EditText视图，我正在这些方法中对纯文本进行加密，并且遇到了某些设备的问题。如果在类中实现了getEditableText()，则该问题将无法在某些设备上通过EditText View显示文本。

我尝试从getEditbaleText()返回加密值Null值和静态值。如果我未实现getEditableText()，它将直接调用父类方法。

//ByDefault method 
@Override
    public Editable getEditableText() {
        return super.getEditableText();
    }
//Modified method 
//Encrypted Value
1)@Override
    public Editable getEditableText() {
        try {
            CharSequence encryptedText = super.getEditableText();
            if (encryptedText != null) {
                Context context = getContext();
                SecureSDKImpl_inner secureSDKImpl_inner = null;
                if (context != null) {
                    secureSDKImpl_inner = new SecureSDKImpl_inner(context);
                    if (secureSDKImpl_inner != null) {
                        encryptedText = secureSDKImpl_inner.EncryptText(encryptedText.toString());
                    }
                } else {
                    Log.d(TAG, null);
                    return null;
                }
            } else {
                Log.d(TAG,"secureSDKImpl_inner is null");
                return null;
            }
            return new Editable.Factory().newEditable(encryptedText);
        } catch (Exception e) {
            e.printStackTrace();
            Log.e(TAG, e.toString());
            return null;
        }
    }
//try to retun null
2)@Override
    public Editable getEditableText() {
     super.getEditableText();
     Editable editable=null;
        return editable;
    }
//try to return null
3) @Override
    public Editable getEditableText() {
        CharSequence encryptedText="";

        return new Editable.Factory().newEditable(encryptedText);

    }

在某些设备上无法在EditText上键入单个字符。主要发生在Gionee，MIUI，EMUI。

我期望从中获取null或加密值 getEditableText()

注意-getText()

没问题

无法在getEditableText（）中经过修改的自定义EditText上显示文本
