我正在尝试为我的应用创建“注册”页面，但无法在所有已正确填写的edittext字段中显示可绘制的“刻度线”。当前，可绘制对象仅显示在最后一个ConfirmPassword EditText中，而不显示在其他对象上，即使它们基本上具有相同的代码。这是我的XML文件-

mCorrectDrawable = getResources().getDrawable(R.drawable.ic_correct, null);
mCorrectDrawable.setBounds(0,0, mCorrectDrawable.getIntrinsicWidth(), mCorrectDrawable.getIntrinsicHeight());
mCorrectDrawable.setTint(getResources().getColor(R.color.colorGreen, null));

请忽略登录，注册等。后端仍未设置。任何帮助，将不胜感激。谢谢！
编辑1 -首先，很抱歉不对代码进行注释。其次，我终于找到了导致此问题的原因。由于EditText.setError（）语句，可绘制对象未显示。我停止使用这些，而是使用它来设置错误消息-
myEditText.setCompoundDrawablesWithIntrinsicBounds(0,0,0,0); //Remove all drawables from the edittext field
myInputLayout.setErrorEnabled(true);
myInputLayout.setError("Passwords do not match");
在这里，InputLayout是与该特定EditText字段相关联的输入。最后，显示可绘制对象-
myInputLayout.setErrorEnabled(false);
myEditText.setCompoundDrawablesWithIntrinsicBounds(null, null, mCorrectDrawable, null);
编辑2 -这是页面的样子-Registration Page 注意，我还编辑了代码，以便仅显示相关代码。很抱歉编辑不当。
