This example demonstrates how do I set the input type for an Android EditText programmatically.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="https://schemas.android.com/apk/res/android" xmlns:tools="https://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:gravity="center_horizontal" android:layout_marginTop="30dp" android:padding="4dp" tools:context=".MainActivity"> <EditText android:id="@+id/editText" android:layout_width="match_parent" android:layout_height="wrap_content"/> <Button android:onClick="SetInputTypeNumber" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Click Here to set EditText input type to number" /> </LinearLayout>
Step 3 − Add the following code to src/MainActivity.java
import androidx.appcompat.app.AppCompatActivity; import android.os.Bundle; import android.text.InputType; import android.view.View; import android.widget.EditText; public class MainActivity extends AppCompatActivity { EditText editText; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); editText = findViewById(R.id.editText); } public void SetInputTypeNumber(View view) { editText.setInputType(InputType.TYPE_CLASS_NUMBER); } }
Step 4 − Add the following code to androidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="https://schemas.android.com/apk/res/android" package="app.com.sample"> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>
Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
