设置OnEditorActionListener监听

mEtSearchInput.setFocusable(true);
mEtSearchInput.setFocusableInTouchMode(true);
mEtSearchInput.requestFocus();
Timer timer = new Timer();
timer.schedule(new TimerTask() {
    public void run() {
        InputMethodManager inputManager = (InputMethodManager) mEtSearchInput.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        inputManager.showSoftInput(mEtSearchInput, 0);
    }
}, 1000);

mEtSearchInput.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        KeyBoardUtil.hideKeyBoard(mEtSearchInput);
        if (actionId == EditorInfo.IME_ACTION_SEARCH) {

        }
        return true;
    }
});
