我可以在android上编写自己的事件吗:imeoptions=“actionsearch”?

这就是我最后使用的:

EditText SearchEditText = (EditText) findViewById(R.id.txtMapSearch);
SearchEditText.setOnEditorActionListener(new OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView arg0, int arg1, KeyEvent arg2) {
        // TODO Auto-generated method stub
        if (arg1 == EditorInfo.IME_ACTION_SEARCH) {
            // search pressed and perform your functionality.
        }
        return false;
    }
});

呼叫 setOnEditorActionListener() 上 EditText 注册 TextView.OnEditorActionListener 当用户点击软键盘上的操作按钮时将调用。
