如何以编程方式添加textinputlayout？
我试过了，
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，当我编译和运行时，会得到以下错误。我在这里做错什么了？

最佳答案
EditText editText = new EditText(this);
LinearLayout.LayoutParams editTextParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT);
TextInputLayout textInputLayout = new TextInputLayout(this);
LinearLayout.LayoutParams textInputLayoutParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
textInputLayout.setLayoutParams(textInputLayoutParams);
textInputLayout.addView(editText, editTextParams);
textInputLayout.setHint("hint");
setContentView(textInputLayout);
