如何以编程方式添加 TextInputLayout ?

How do i go about adding a TextInputLayout programmatically ?

我尝试过，

private EditText _editText; private TextInputLayout _textInputLayout; // Create the EditText if (_editText == null) { _editText = new EditText(this.getContext()); _editText.setInputType( _isPassword ? InputType.TYPE_TEXT_VARIATION_PASSWORD : InputType.TYPE_TEXT_FLAG_AUTO_CORRECT ); _editText.setLayoutParams( new LayoutParams(0, LayoutParams.MATCH_PARENT) ); if (_hint != null) { _editText.setHint(String.format("%s%s", HINT_PREFIX, _hint.toLowerCase())); } _textInputLayout = new TextInputLayout(this.getContext()); _textInputLayout.setLayoutParams( new LayoutParams(0, LayoutParams.WRAP_CONTENT, EDIT_TEXT_WEIGHT) ); _textInputLayout.addView(_editText); this.addView(_textInputLayout); }

但是，当我编译并运行时，出现以下错误.我在这里做错了什么?

However, when i compile and run i get the following error. What am i doing wrong here ?

推荐答案

最终使用了 MaterialEditText 库.这比我遇到的大多数其他库具有更多的功能.

Ended up using MaterialEditText libraries. This has way more features than most of the other libraries I have come across.
