以编程方式打开软键盘

Question

I have an activity with no child widgets for it and the corresponding xml file is,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/myLayout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:focusable="true"
>
</LinearLayout>

and I want to open soft keyboard programmatically while the activity gets start.and what I've tried upto now is,

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    if (inputMethodManager != null) {
        inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
    }

Give me some guidance.

Answer 1

I have used the following lines to display the soft keyboard manually inside the onclick event, and the keyboard is visible.

InputMethodManager inputMethodManager =
    (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.toggleSoftInputFromWindow(
    linearLayout.getApplicationWindowToken(),
    InputMethodManager.SHOW_FORCED, 0);

But I'm still not able to open this while the activity gets opened, so are there any solution for this?

Answer 2

In your manifest file, try adding the following to the <activity> that you want to show the keyboard when the activity starts:

android:windowSoftInputMode="stateVisible"

This should cause the keyboard to become visible when the activity starts.

For more options, checkout the documentation .

Answer 3

Please follow the below code. I am sure your problem will be solved.

if (imm != null){
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
   } 

Answer 4

This is works

<activity
    ...
    android:windowSoftInputMode="stateVisible" >
</activity>

or

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

Answer 5

All I needed was to expose the keyboard, in a very precise moment. This worked for me! Thanks Benites.

    private Handler mHandler= new Handler();

And in the very precise moment:

    mHandler.post(
    new Runnable() {
        public void run() {
            InputMethodManager inputMethodManager =  (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
            inputMethodManager.toggleSoftInputFromWindow(yourEditText.getApplicationWindowToken(), InputMethodManager.SHOW_FORCED, 0);
            yourEditText.requestFocus();
        }
    }); 

Answer 6

I have used the following lines to display the soft keyboard manually inside the onclick event.

public void showKeyboard(final EmojiconEditText ettext){
          ettext.requestFocus();
          ettext.postDelayed(new Runnable(){
            @Override public void run(){
              InputMethodManager keyboard=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
              keyboard.showSoftInput(ettext,0);
            }
          }
        ,200);
        }

Answer 7

Kotlin

fun hideKeyboard(activity: Activity) {
    val view = activity.currentFocus
    val methodManager = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    assert(view != null)
    methodManager.hideSoftInputFromWindow(view!!.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
}

private fun showKeyboard(activity: Activity) {
    val view = activity.currentFocus
    val methodManager = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    assert(view != null)
    methodManager.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT)
}

Java

public static void hideKeyboard(Activity activity) {
    View view = activity.getCurrentFocus();
    InputMethodManager methodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    assert methodManager != null && view != null;
    methodManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}

private static void showKeyboard(Activity activity) {
    View view = activity.getCurrentFocus();
    InputMethodManager methodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    assert methodManager != null && view != null;
    methodManager.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT);
}

Answer 8

Put that in onResume method:

findViewById(R.id.root_view_of_your_activity_layout).post(
new Runnable() {
    public void run() {
        InputMethodManager inputMethodManager =  (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
        inputMethodManager.toggleSoftInputFromWindow(yourEditText.getApplicationWindowToken(),     InputMethodManager.SHOW_FORCED, 0);
        yourEditText.requestFocus();
    }
});

the runnable is needed because when the OS fires the onResume method you can't be sure that all the views where draw, so the post method called from your root layout makes it wait till every view is ready.

Answer 9

in onCreate method of activity or onActivityCreated of a fragment

....
view.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
        @Override
        public boolean onPreDraw() {
            view.removeOnPreDrawListener(this);
            InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

            // !Pay attention to return `true`
            // Chet Haase told to 
            return true;
        }
    });

Answer 10

seems like this is working

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_patientid);

        editText = (EditText)findViewById(R.id.selectPatient);
        //editText.requestFocus(); //works without that

    }

@Override
    protected void onResume() {

        findViewById(R.id.selectPatient).postDelayed(
        new Runnable() {
            public void run() {
                 editText.requestFocus();
                InputMethodManager inputMethodManager =  (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                inputMethodManager.showSoftInput(editText,InputMethodManager.SHOW_IMPLICIT);
            }
        },100);
        super.onResume();
    }

seems this works better: in manifest:

<application>
    <activity
        android:name="com.doodkin.myapp.ReportActivity"
        android:label="@string/title_activity_report"
        android:screenOrientation="sensor" 
        android:windowSoftInputMode="stateHidden" > // add this or stateVisible
    </activity>
</application>

seems the manifest working in android 4.2.2 but not working in android 4.0.3

Answer 11

I used it as singleton like:

public static void showSoftKeyboard(final Context context, final EditText editText) {
        try {
            editText.requestFocus();
            editText.postDelayed(
                    new Runnable() {
                        @Override
                        public void run() {
                            InputMethodManager keyboard = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
                            keyboard.showSoftInput(editText, 0);
                        }
                    }
                    , 200);
        } catch (NullPointerException npe) {
            npe.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Use it in your activity like:

showSoftKeyboard(this, yourEditTextToFocus);

Answer 12

I have used like this to show the soft keyboard programatically and this is worked for me to prevent the auto resize of the screen while launching the keyboard.

In manifest:

<activity android:name="XXXActivity" android:windowSoftInputMode="adjustPan">
</activity>

In XXXActvity:

EditText et =  (EditText))findViewById(R.id.edit_text);  
  Timer timer = new Timer();
            TimerTask task = new TimerTask() {

                @Override
                public void run() {
                    InputMethodManager inputMethodManager=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                    inputMethodManager.toggleSoftInputFromWindow(et.getApplicationWindowToken(), InputMethodManager.SHOW_FORCED, 0);

                }
            };
            timer.schedule(task, 200);

I assume this will save others time to search for this problem.

Answer 13

InputMethodManager inputMethodManager=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
            inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

Answer 14

This works:

private static void showKeyboard(Activity activity) {
    View view = activity.getCurrentFocus();
    InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}

And you call this method like this:

showKeyboard(NameOfActivity.this);

Answer 15

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

在 onResume() 中使用上述代码打开软键盘

Answer 16

InputMethodManager.SHOW_FORCED isn't good choice. If you use this setting you should manage hiding keyboard state. My suggestion is like this;

    public void showSoftKeyboard(View view) {
    InputMethodManager inputMethodManager = (InputMethodManager) getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
    view.requestFocus();
    inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);
}

Also, you can focus on view (usually EditText) taking parameters it. This makes it a more useful function

Answer 17

public final class AAUtilKeyboard {

public static void openKeyboard(final Activity activity, final EditText editText) {
    final InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    if (imm != null) {
        imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
    }
}

public static void hideKeyboard(final Activity activity) {
    final View view = activity.getCurrentFocus();
    if (view != null) {
        final InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm != null) {
            imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
        }
    }
}

Answer 18

perfectly working code to show and hide softkeyboard for edittextbox.....

// code to hide soft keyboard
public void hideSoftKeyBoard(EditText editBox) {
     InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);  
     imm.hideSoftInputFromWindow(editBox.getWindowToken(), 0);  
}




// code to show soft keyboard
private void showSoftKeyBoard(EditText editBox){
     InputMethodManager inputMethodManager = (InputMethodManager) this.getSystemService(Activity.INPUT_METHOD_SERVICE);
     editBox.requestFocus();
     inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}

Answer 19

Based on above answers like this it works in KOTLIN as long as you have the context.

fun Context.showKeyboard(editText: EditText) {

    editText.requestFocus()
    editText.setSelection(editText.text.length)

    GlobalScope.launch {
        delay(200L)

        val inputMethodManager: InputMethodManager =
            getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        inputMethodManager.toggleSoftInputFromWindow(
            editText.applicationWindowToken,
            InputMethodManager.SHOW_IMPLICIT, 0
        )
    }
}

Then you can call it in your fragment for example as follows

requireContext().showKeyboard(binding.myEditText)

Answer 20

import androidx.core.view.WindowInsetsCompat.Type
import androidx.core.view.WindowInsetsControllerCompat

fun Activity.openKeyboard() {
    WindowInsetsControllerCompat(window, window.decorView).show(Type.ime())
}

fun Activity.hideKeyboard() {
    WindowInsetsControllerCompat(window, window.decorView).hide(Type.ime())
}

Answer 21

Similar to the answer of @ShimonDoodkin this is what I did in a fragment.

https://stackoverflow.com/a/29229865/2413303

    passwordInput.postDelayed(new ShowKeyboard(), 300); //250 sometimes doesn't run if returning from LockScreen

Where ShowKeyboard is

private class ShowKeyboard implements Runnable {
    @Override
    public void run() {
        passwordInput.setFocusableInTouchMode(true);
        passwordInput.requestFocus();            
        getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
        ((InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE)).showSoftInput(passwordInput, 0);
    }
}

After a successful input, I also make sure I hide the keyboard

getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
((InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE))
                    .hideSoftInputFromWindow(getView().getWindowToken(), 0);

Answer 22

This is the required source code :

public static void openKeypad(final Context context, final View v) 
 {
new Handler().postDelayed(new Runnable() 
{
    @Override
    public void run() 
    {
        InputMethodManager inputManager =   (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE); 
        inputManager.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);    
        Log.e("openKeypad", "Inside Handler");
    }
},300);}

For details , Please go through this link. This helped me. https://github.com/Nikhillosalka/Keyboard/blob/master/README.md

Answer 23

There are already too many answers but nothing worked for me apart from this

inputMethodManager.showSoftInput(emailET,InputMethodManager.SHOW_FORCED);

I used showSoftInput with SHOW_FORCED

And my activity has

 android:windowSoftInputMode="stateVisible|adjustResize"

hope this helps someone

Answer 24

Post this method in your base activity and use it other activities like a charm

public void openKeyboard() {
    InputMethodManager imm =
            (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    if (imm != null) {
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
    }
}

Answer 25

I like to do it as an extension to Context so you can call it anywhere

fun Context.showKeyboard(editText: EditText) {
    val inputMethodManager: InputMethodManager =
        getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    inputMethodManager.toggleSoftInputFromWindow(
        editText.applicationWindowToken,
        InputMethodManager.SHOW_IMPLICIT, 0
    )
    editText.requestFocus()
    editText.setSelection(editText.text.length)
}

fun Context.hideKeyboard(editText: EditText) {
    val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(editText.windowToken, 0)
}

Answer 26

If you want the keyboard to be up along with the activity/fragment launch, you can use the below code.

new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                InputMethodManager inputMethodManager =
                        (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
                inputMethodManager.toggleSoftInputFromWindow(
                        etPhoneNumber.getApplicationWindowToken(),
                        InputMethodManager.SHOW_FORCED, 0);
            }
        }, 500);

Answer 27

In the Kotlin , you can use the below extension functions to show and hide the soft keyboard.

/**
  * Extension method to provide show keyboard for [Activity].
 */
fun Activity.showSoftKeyboard() {
  if (currentFocus != null) {
    val inputMethodManager =
        getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
 inputMethodManager.showSoftInput(this.currentFocus,InputMethodManager.SHOW_IMPLICIT)
   } 
}


/**
 * Extension method to provide hide keyboard for [Activity].
 */
fun Activity.hideSoftKeyboard() {
   if (currentFocus != null) {
      val inputMethodManager =
        getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    inputMethodManager.hideSoftInputFromWindow(currentFocus!!.windowToken, 0)
    }
 }

That's all! Cheers!

Answer 28

Best way to open forced Keyboard is call below kotlin code code:-

 val inputMethodManager: InputMethodManager =
            getSystemService(INPUT_METHOD_SERVICE) as InputMethodManager

        inputMethodManager.showSoftInput(
            editText, 2)

Answer 29

Try use this:

    fun closeKeyboard(view: View) {
    (getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager)
        .hideSoftInputFromWindow(view.windowToken, HIDE_IMPLICIT_ONLY)
}

fun showKeyBoard(view: View) {
    (getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager).showSoftInput(
        view,
        SHOW_IMPLICIT
    )
}

And if not work, try wrap func in a run block like this:

  view.postDelayed({showKeyBoard(view)},100)
