android popup message

Android Studio is the best option to create your app as an android developer or just a guy who wants to make an android app. However, writing code and having errors is pervasive in any type of development.

 

Using Logcat, you can solve the error of Android Studio. Here you will see how to display android popup message or error message. First, we will start with How you can display error messages in the app for a user, and then one by one, you will see an error in Android Studio.

 

How To Display Android Popup Message Or Error Message?

 

Android Studio Popup Message

 

In genarel, error or confirmation message is easy to show. To show message, create a Button in android studio. Write this code below to the folder name activity_main.xml.

 

<?xml version=1.0″ encoding=”utf-8″?>

<RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android”

xmlns:app=”http://schemas.android.com/apk/res-auto”

xmlns:tools=”http://schemas.android.com/tools”

android:layout_width=”match_parent”

android:layout_height=”match_parent”

tools:context=”com.example.application.example.MainActivity”>

<!– This is the button layout for your app. –>

<Button

android:id=”@+id/button”

android:layout_width=”wrap_content”

android:layout_height=”wrap_content”

android:layout_centerHorizontal=”true”

android:layout_centerVertical=”true”

android:text=”open dialog” />

<!– In this place you can add other element code too. You can rearrange this above tag with other elements in your app. –>

</RelativeLayout>

 

The above code will create representation of a Button on your android app. Then the main part, interaction with button. In below code that button will interect with interface. To interect, you have to write code inside of MainActivity.java this folder. and for logics having an external class file is much more clean and best practics.

 

package com.example.application.example;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

public class MainActivity extends AppCompatActivity {

<!– Declring A button –>

private Button messageButton;

@Override

protected void onCreate( Bundle savedInstanceState ) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

messageButton= (Button) findViewById(R.id.messageButton);

messageButton.setOnClickListener(newView.OnClickListener() {

@Override

public void onClick(View view) {

openDialog();

} });}

<!– Call a class to write logics behind popup –>

public void openDialog() {

ExampleDialog exampleDialog =new dialog();

dialog.show(getSupportFragmentManager(), “Dialog”);

}}

 

After this, You can write your class proparties in a class named with Dialog.java and there write this folloing code.

package com.example.application.example;

 

import android.app.Dialog;

import android.content.DialogInterface;

import android.os.Bundle;

import android.support.v7.app.AlertDialog;

import android.support.v7.app.AppCompatDialogFragment;

public class ExampleDialog extends AppCompatDialogFragment {

@Override

public Dialog onCreateDialog(Bundle savedInstanceState) {

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

builder.setTitle(“Dialog Box”)

.setMessage(“Write your dialog here”)

.setPositiveButton(“Agree”, new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialogInterface, int i) {

}

});

return builder.create();

}

}

 

In the Set message option, you can write your message. And that message will be shown there. You can offer a confirmation message or some message popup in the android app by this method.

 

Android Error Message Popup On Form Submission

 

Suppose you want to build a registration form. There, you want to get name, email, and password. And want to get all info for registration. If someone tries to pass without giving information, that will show invalid input.

 

On the other hand, you want to place input validation for a registration form submission. Go to the mistakes activity_main.xml file and write this code to see graphical representation on your android app.

 

<?xml version=”1.0″ encoding=”utf-8″?>

<ScrollView

</LinearLayout>

</android.support.v7.widget.CardView>

</ScrollView>

 

If you have write this code correctly then go to MainActivity.java page to write code for interact with your activity mainxml file.

 

package com.elevenzon.TextInputLayout;

import android.content.Intent;

import android.util.Patterns;

import android.support.design.widget.TextInputLayout;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.TextView;

import android.widget.Toast;

import android.widget.EditText;

public class RegisterActivity extends AppCompatActivity {

EditText name, email, password;

Button register;

boolean isNameValid, isEmailValid, isPasswordValid;

TextInputLayout nameError, emailError, passError;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

name = (EditText) findViewById(R.id.name);

email = (EditText) findViewById(R.id.email);

password = (EditText) findViewById(R.id.password);

register = (Button) findViewById(R.id.register);

nameError = (TextInputLayout) findViewById(R.id.nameError);

emailError = (TextInputLayout) findViewById(R.id.emailError);

passError = (TextInputLayout) findViewById(R.id.passError);          

register.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

SetValidation();

}

});               

}        

public void SetValidation() {

<!– Name Validation –>

if (name.getText().toString().isEmpty()) {

nameError.setError(getResources().getString(R.string.name_error));

isNameValid = false;

} else {

isNameValid = true;

nameError.setErrorEnabled(false);

}        

<!– Email Validation –>

if (email.getText().toString().isEmpty()) {

emailError.setError(getResources().getString(R.string.email_error));

isEmailValid = false;

          } else if (!Patterns.EMAIL_ADDRESS.matcher(email.getText().toString()).matches()) {

emailError.setError(getResources().getString(R.string.error_invalid_email));

isEmailValid = false;

} else {

isEmailValid = true;

emailError.setErrorEnabled(false);

}        

<!– Password Validation –>

if (password.getText().toString().isEmpty()) {

passError.setError(getResources().getString(R.string.password_error));

isPasswordValid = false;

          } else if (password.getText().length() < 6) {

passError.setError(getResources().getString(R.string.error_invalid_password));

isPasswordValid = false;

} else {

isPasswordValid = true;

passError.setErrorEnabled(false);

}

          <!– Validation Check –>    

if (isNameValid && isEmailValid && isPasswordValid) {

Toast.makeText(getApplicationContext(), “Successfully”, Toast.LENGTH_SHORT).show();

}

}

}

 

This is how you can make a validation error for form validation. Now you will see some common errors and how to solve those errors in detail.
