有没有一种方法可以隐藏键盘而不丢失EditText的焦点

Question

When you click the back button, the keyboard hides itself but the focus on the edittext remains. How can I reproduce this behaviour?

Answer 1

You can use this code to hide the keyboard:

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

Or this one :

View view = this.getCurrentFocus();
if (view != null) {  
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

If the EditText loses the focus, simple write a simple command

editText.requestFocus();
