软键盘显示搜索及监听

EditText需要设置两个属性:imeOptions = actionSearch和singleLine = true

//搜索监听
etSearch.setOnEditorActionListener(new TextView.OnEditorActionListener() {
            @Override
            public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
                if (actionId == EditorInfo.IME_ACTION_SEARCH ||
                        (keyEvent != null && keyEvent.getKeyCode() == KeyEvent.KEYCODE_ENTER) ) {

		//隐藏键盘
                    ((InputMethodManager) etSearch.getContext()
                            .getSystemService(Context.INPUT_METHOD_SERVICE))
                            .hideSoftInputFromWindow(MainActivity.this
                                            .getCurrentFocus().getWindowToken(),
                                    InputMethodManager.HIDE_NOT_ALWAYS);
                //这里进行搜索...
                    return true;
                }
                return false;
            }
        });
