android.support.design.widget.TextInputLayout could not be instantiated

Question

I want to integrate android.support.design.widget.TextInputLayout In my android application. I have copied the jar file android-support-design.jar from the sdk to my applications lib folder. I have added below code in my xml file for the Email EditText,

 <!-- Email Label -->
        <android.support.design.widget.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="8dp"
            android:layout_marginBottom="8dp">
            <EditText android:id="@+id/input_email"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:inputType="textEmailAddress"
                android:hint="Email" />
        </android.support.design.widget.TextInputLayout>

While add this code in my layout.xml file I am getting an error like,

Exception raised during rendering: com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup
Exception details are logged in Window > Show View > Error Log
The following classes could not be instantiated:
- android.support.design.widget.TextInputLayout (Open Class, Show Error Log)
See the Error Log (Window > Show View) for more details.

How can i fix this issue...

Solution 1

If you uses AndroidStudio, you should not include android-support-design.jar. Instead, write like below in your build.gradle:

dependencies {
    ...
    compile 'com.android.support:design:24.0.0'
    ...
}

Edit: If this doesn't work you are probably using a different version. In Windows, go to:

[android-sdk]\extras\android\m2repository\com\android\support\design

On Mac:

sdk/extras/android/m2repository/com/android/support/design

This directory holds a number of version folders. Use the latest version on your build.gradle.

Solution 2

replace

android.support.design.widget.TextInputLayout

with

com.google.android.material.textfield.TextInputLayout

Solution 3

add in the build.gradle following this line:

implementation 'com.android.support:design:28.0.0'

and use in the xml file:

 <com.google.android.material.textfield.TextInputLayout
                    android:id="@+id/inputLayoutMobile"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_marginLeft="@dimen/dimen_20dp"
                    android:layout_marginRight="@dimen/dimen_20dp"
                    android:hint="@string/phone_number"
                    android:visibility="gone"
                    android.support.design:layout_constraintTop_toBottomOf="@+id/inputLayoutAppServerUrl">

                    <com.google.android.material.textfield.TextInputEditText
                        android:id="@+id/edtTxtMobile"
                        style="@style/Style_TextView"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:drawableLeft="@drawable/ic_smartphone"
                        android:drawablePadding="@dimen/dimen_10dp"
                        android:inputType="number"
                        android:singleLine="true"
                        android:scrollbars="vertical"
                        android:text="@={SettingViewModel.mMobileNo}"
                        android:textSize="@dimen/font_13sp" />
                </com.google.android.material.textfield.TextInputLayout>

Solution 4

For android androidX add this dependencies

implementation 'com.google.android.material:material:1.2.0'

Then try

Solution 5

The dependency your using is part of the Android support library which is now deprecated and no longer supported by Google. Instead, use this:
implementation 'com.google.android.material:material:<version>'
and replace <version> with the latest version from either Google's Maven Repository or MVN Repository

I am using Eclipse for development

You should import support-v7-appcompat library. see stackoverflow.com/a/31431076/5183999

[SHIDHIN.T.S]

Thanks Its worked for me... I have added the library project from android-sdks\extras\android\support\design

[Kwnstantinos Nikoloutsos]

Shouldn't we use androidx libraries?

[SaadurRehman]

there is no relevance of setting id , TextInputLayout is a part of material design library so we need to add the relevant library to get its intellisense autofill in xml.
