问题描述

我有一个SearchView.当用户单击键盘搜索按钮时，我需要进行服务器呼叫.侦听器的代码是什么样的?我在想我必须使用OnClickListener.但是，由于知道它是搜索按钮的内部代码，所以我不确定如何确定它.

I have a SearchView. When the user clicks on the keyboard search button, I need to make a server call. What does the code for the listener look like? I am thinking I have to use OnClickListener. But the internal code for knowing it's the search button, I am not sure how to determine that.

推荐答案

我已经这样做了

onQueryTextSubmit是您要寻找的方法.

在搜索视图中设置setOnQueryTextListener.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);

    MenuItem searchItem = menu.findItem(R.id.search_city);
    searchView = (SearchView) searchItem.getActionView();
    searchView.setQueryHint("Search View Hint");

    searchView.setOnQueryTextListener(new OnQueryTextListener() {

        @Override
        public boolean onQueryTextChange(String newText) {
            //Log.e("onQueryTextChange", "called");
            return false;
        }

        @Override
        public boolean onQueryTextSubmit(String query) {


            // Do your task here

            return false;
        }

    });

    return true;
}
