EditText

控制确认键操作

通过EditText的imeOptions属性可以指定动作。

<EditText
    android:id="@+id/et_search"
    android:layout_width=“match_parent”
    android:layout_height="match_parent"
    android:singleLine="true"
    android:imeOptions="actionSearch"
    />

操作监听器。

mSearchEditText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if (actionId == EditorInfo.IME_ACTION_SEARCH ||
                    actionId == EditorInfo.IME_ACTION_DONE ||
                    event.getAction() == KeyEvent.ACTION_DOWN &&
                            event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
                            search();
                return true;
            }
            return false;
        }
    });
