Hide softkeyboard for locker app

I'm trying to close the softkeyboard that is opened in another app. I tried every solution from here: Programmatically Hide/Show Android Soft Keyboard or here: Close/hide the Android Soft Keyboard

As you can see in the pictures i have to close the keyboard opened from another app, adding to manifest to don't make the keyboard visible didn't make the trick.

To note that this is a locker app, i start an activity when the phone goes to sleep mode.

Am i missing something ? Testing other locker apps from store and didn't encountered this problem

But here is the result:

Edit: More info

This is how i start the locker:

if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
    //Toast.makeText(context, "" + "screeen off", Toast.LENGTH_SHORT).show();

    wasScreenOn = false;
    Intent intent = new Intent(context, LockScreenActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
    intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

    context.startActivity(intent);

    // do whatever you need to do here
    //wasScreenOn = false;
} 

This is the manifest code:

<activity
    android:name=".ui.activities.LockScreenActivity"
    android:excludeFromRecents="true"
    android:noHistory="true"
    android:screenOrientation="portrait"
    android:windowSoftInputMode="stateAlwaysHidden|adjustNothing"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar" />

---

Try replacing android:windowSoftInputMode="stateAlwaysHidden|adjustNothing" with android:windowSoftInputMode="stateHidden" line in AndroidManifest.xml like this

<activity
        android:name=".ui.activities.LockScreenActivity"
        android:excludeFromRecents="true"
        android:noHistory="true"
        android:screenOrientation="portrait"
        android:windowSoftInputMode="stateHidden"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar" />

For reference, you can refer http://developer.android.com/guide/topics/manifest/activity-element.html#wsoft

"stateHidden" The soft keyboard is hidden when the user chooses the activity — that is, when the user affirmatively navigates forward to the activity, rather than backs into it because of leaving another activity.

"stateAlwaysHidden" The soft keyboard is always hidden when the activity's main window has input focus.

它可以实现覆盖此活动的onPause()并使用以下代码片段

@Override
public void onPause() {
    super.onPause();
    if (null != getWindow()){
        getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
    }
}

---

在你的活动中试试这个：

private void hideKeyboard() {   
    // Check if no view has focus:
    View view = this.getCurrentFocus();
    if (view != null) {
        InputMethodManager inputManager = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
        inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    }
}
