Question

我试图在操作栏上放置一个搜索按钮。我在屏幕上有一个列表，在搜索任何文本列表时将刷新并在同一屏幕上显示该文本数据。

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    final MenuItem item = menu.findItem(R.id.search);
     return true;
}

点击搜索按钮消费和软键盘显示搜索按钮进行搜索。

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {

        case R.id.search:
            // startSearchActivity();
            MenuItemCompat.expandActionView(item);
            SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);

            searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

                @Override
                public boolean onQueryTextSubmit(String text) {
                    Toast.makeText(getApplicationContext(), "dddddd " + text, Toast.LENGTH_LONG).show();
                    return true;
                }

                @Override
                public boolean onQueryTextChange(String text) {
                    Toast.makeText(getApplicationContext(), "sssssss " + text, Toast.LENGTH_LONG).show();
                    return true;
                }
            });
            break;

        default:
            break;
    }
    return super.onOptionsItemSelected(item);
}

但软键盘的搜索按钮未显示任何操作。请告诉我什么是错的..

在 onCreateOptionsMenu 中实施 setOnQueryTextListener ，而不是 onOptionsItemSelected

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        MenuItem searchItem = menu.findItem(R.id.search);
        MenuItemCompat.expandActionView(searchItem);

        SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);

        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

            @Override
            public boolean onQueryTextSubmit(String text) {
                Toast.makeText(getApplicationContext(), "dddddd " + text, Toast.LENGTH_LONG).show();
                return true;
            }

            @Override
            public boolean onQueryTextChange(String text) {
                Toast.makeText(getApplicationContext(), "sssssss " + text, Toast.LENGTH_LONG).show();
                return true;
            }
        });
        return true;
    }
