Java 如何使用代码动态更改TextInputLayout错误颜色和错误文本大小

这是代码动态比如何更改错误消息的颜色和文本大小

TextInputLayout input
input = new TextInputLayout(this);
input.setTypeface(tf);
input.setLayoutParams(lparams);
input.setTypeface(tf);

您必须使用定义自定义样式并将此行添加到您的

TextInputLayout

应用程序：errorTextAppearance=“@style/custom\u textColor\u style”

我找到了此项的解决方案。我在我的代码中这样做

首先对TextInputLayout和Edittext Layout生成Xml

<!-- Text Input Layout-->
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.TextInputLayout  xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
app:errorTextAppearance="@style/TextLabelInput"
 />

<!-- Edittext Layout -->
<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="@color/txt_color"
android:textColorHint="@color/txt_color"
android:textColorHighlight="@color/txt_color"
android:textSize="21sp" />

我在XMl中使用它，但我希望在Java编码中实际使用它

TextInputLayout input

input = new TextInputLayout(this);
  input =(TextInputLayout)getLayoutInflater().inflate(R.layout.row_inputlayout_item, null);

input.setLayoutParams(lparams);
input.setTypeface(tf);


et = new EditText(this);
et = (EditText)getLayoutInflater().inflate(R.layout.row_edittext_form, null);
et.setId(Integer.parseInt(item.getFieldid()));
et.setLayoutParams(lparams);
et.setHint(item.getLabel());
input.addView(et);
rl_MainLayout1.addView(input);
