java - 当edittext不为空时如何自动按回车键？

Question

我正在创建一个 EditText 和从 Firebase 获得的值，如果 edittext 不为空，则可能会自动按下 Enter 键

private void init(){
    Log.d(TAG, "init: initializing");

    if (mSearchText != null){
       what must i write here?
    }

    mSearchText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
            if(actionId == EditorInfo.IME_ACTION_SEARCH
                    || actionId == EditorInfo.IME_ACTION_DONE
                    || keyEvent.getAction() == KeyEvent.ACTION_DOWN
                    || keyEvent.getAction() == KeyEvent.KEYCODE_ENTER){

                //execute our method for searching
                geoLocate();
            }

            return false;
        }
    });

Answer 1

[1]您可以尝试下面的代码

String yourtext=mSearchText.getText().toString().trim();
if(!TextUtils.isEmpty(yourtext)) //or else you can use  if(yourtext!=null && !yourtext.equalsIgnoreCase(""))
{
    mSearchText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
            if(actionId == EditorInfo.IME_ACTION_SEARCH
                    || actionId == EditorInfo.IME_ACTION_DONE
                    || keyEvent.getAction() == KeyEvent.ACTION_DOWN
                    || keyEvent.getAction() == KeyEvent.KEYCODE_ENTER){

                //execute your method for searching
                geoLocate();
            }

            return false;
        }
    });
}

[2]否则你可以使用这个(直接方法调用)来实现你的功能

String yourtext=mSearchText.getText().toString().trim();
if(!TextUtils.isEmpty(yourtext)) //or else you can use  if(yourtext!=null && !yourtext.equalsIgnoreCase(""))
{
     //execute your method for searching
                geoLocate();
}
