Automatically show text of error in EditText

Question

I'm using code like

EditText.setError("Something went wrong");

to show an error on an EditText. But only the exclamation mark icon is shown, not the text of the error. Clicking on it shows the error text.

How can I have the error text display automatically, without needing to touch the icon first?

Answer 1

您可以将焦点设置为EditText，这样用户就不必点击它。

editText.requestFocus()

但是，这仍然只能一次显示一个错误。我相信这可能仍然是最好的方式，因为这是平台实现它的方式。

   //  In you layout Xml

     <android.support.design.widget.TextInputLayout
                    android:layout_width="match_parent"
                    android:id="@+id/layFName"
                    android:textColorHint="@color/edittext_hintcolor"
                      app:hintTextAppearance="@style/TextAppearence.App.TextInputLayout"
                    android:layout_height="wrap_content">
                    <EditText
                        android:id="@+id/et_name_registration"
                        android:inputType="textPersonName"
                        android:hint="Hint Text"

                        />
                </android.support.design.widget.TextInputLayout>

// In java
 private TextInputLayout mLayFName;
 mLayFName = (TextInputLayout) findViewById(R.id.layFName);

for set error

 mInputLayoutView.setError(msg);
            EditText.getBackground().setColorFilter(getResources().getColor(R.color.red), PorterDuff.Mode.SRC_ATOP);}
