Android Material Design TextInputEditText not able to get the string
I am using material design in my android app registration page. I have used the following code in my xml file.
XML File
<com.google.android.material.textfield.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/regEmailId"
android:hint="Email Id"
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</com.google.android.material.textfield.TextInputLayout>
The above xml is rendered from inside a linear layout.
In my Java file, I have written the following:
TextInputLayout regMailId = findViewById(R.id.regEmailId);
Editable regEmail = regMailId.getEditText().getText();
I followed the option given in this SO post here. Though the answer indicates I should use
String text = textInputLayout.getEditText().getText();
I am getting an error with Android Studio forcing me to change this to:
Change variable text type to editable
Migrate text type to editable
Wrap using String.valueOf()
If I wrap using string value of
String text = String.valueOf( regMailId.getEditText().getText() );
I am not getting the output of variable text.
When I changed it to
Editable regEmail = regMailId.getEditText().getText();
I am able to toast the input text, but I could not get the actual text to do any validations on top of them. For example, the password
and confirmpassword
fields, I am not able to compare though I could see the values getting toasted.
When I tried to get the variable type for regEmail
, I got the following toasted:
java.lang.String.android.text.SpannableStringBuilder
I tried extracting string by using toString(), getText().toString(), etc to the regEmail. Nothing worked.
How do I get the string of the textinput field in material design layout.
The following is my app gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 29
defaultConfig {
applicationId "com.example.telescope"
minSdkVersion 16
targetSdkVersion 29
versionCode 1
versionName "1.0"
multiDexEnabled true
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
implementation 'com.google.android.material:material:1.2.0'

}
Solution 1:
To get the text in the 'real time', you should add TextChangeListener to the EditText object:
TextInputLayout regMailId = findViewById(R.id.regEmailId);
regEmailId.getEditText().addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {}
public void beforeTextChanged(CharSequence s, int start,
int count, int after) {}
public void onTextChanged(CharSequence s, int start,
int before, int count) {
//get the String from CharSequence with s.toString() and process it to validation
}
});
