How do I remove the keyboard after I finish an activity?

问题

I have an activity that users type inside and then click the ok button. When it is finished, the activity closes and goes back to the old activity but the soft keyboard is still on the screen! I've tried android:windowSoftInputMode="stateHidden" and

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

But it does nothing.

回答1:

In OnPause of your activity, you should do the following

InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(et.getWindowToken(), 0);

Where et is an instance of your EditText.
