How to close or hide the virtual keyboard on Android?
In Android there are some situations, we should close android default keyboard forcefully. For that this example is help for you.
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"?> <android.support.constraint.ConstraintLayout 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 = ".MainActivity"> <EditText android:id = "@+id/editext" android:layout_width = "match_parent" android:layout_height = "wrap_content"> </EditText> <Button android:id = "@+id/button" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:text = "Click here to hide" app:layout_constraintBottom_toBottomOf = "parent" app:layout_constraintLeft_toLeftOf = "parent" app:layout_constraintRight_toRightOf = "parent" app:layout_constraintTop_toTopOf = "parent" /> </android.support.constraint.ConstraintLayout>
Step 3Add the following code to src/MainActivity.java
import android.app.ProgressDialog;
import android.os.Build;
import android.os.Bundle;
import android.os.Handler;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ProgressBar;
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
Handler mHandler;
ProgressDialog mProgressBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = findViewById(R.id.button);
EditText editext = findViewById(R.id.editext);
editext.requestFocus();
button.setOnClickListener(this);
}
@RequiresApi(api = Build.VERSION_CODES.O)
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button:
hideKeybaord(v);
break;
}
}
private void hideKeybaord(View v) {
InputMethodManager inputMethodManager = (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(v.getApplicationWindowToken(),0);
}
}In the above code when you click on the button it will hide keyboard. To hide keyboard, use the following code.
InputMethodManager inputMethodManager = (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE); inputMethodManager.hideSoftInputFromWindow(v.getApplicationWindowToken(),0);
Step 5 − Add the following code to manifest file as shown below.
<?xml version = "1.0" encoding = "utf-8"?> <manifest xmlns:android = "http://schemas.android.com/apk/res/android" package = "com.example.andy.myapplication"> <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" android:windowSoftInputMode = "stateAlwaysVisible"> <intent-filter> <action android:name = "android.intent.action.MAIN" /> <category android:name = "android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>
In the above code it contains windowSoftInputMode, it means it will show keyboard always when edit text is request focused.
