java - 如何在文本框下方显示地点建议？

Question

我正在将 mapbox 用于我想在文本框下方显示位置建议的应用程序...

下面是我的代码，

在我的代码中，发生的事情是在单击作为浮动操作按钮的搜索按钮后，会打开一个搜索栏，它允许我们搜索地点......然后将标记放置到该位置

看起来像这样

    }

    @Override

        super.onStart();
        mapView.onStart();
    }

    @Override
    protected void onStop() {
        super.onStop();
        mapView.onStop();
    }

    @Override
    public void onPause() {
        super.onPause();
        mapView.onPause();
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        mapView.onLowMemory();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        mapView.onDestroy();
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        mapView.onSaveInstanceState(outState);
    }


}

但我想要实现的是我想使用一个 EditText 作为搜索框并在 edittext 下方显示结果（建议）......

我怎样才能做到这一点？
