如何在Google地图上的用户当前位置附近获取和显示餐馆/酒吧/电影院等？

Question

我创建了一个基于Android的移动应用程序，可以在Google地图上显示靠近用户的餐馆，酒吧和其他有趣的地方。我可以将用户的当前位置显示在Google上的地图上直到这一点。但是我无法弄清楚如何向Google Place API发送参数来显示相关信息。（我也已经阅读了有关地方API的文档）

我的MainActivity有4个按钮，因此单击1＆1;应该显示1英里半径范围内的用户餐馆（mapsActivity）。

非常感谢示例代码。代码是否在mapsActivity中，我可以使用代码获取用户的当前位置，还是创建新类？

请帮忙！ 谢谢:)）

到目前为止我的代码：

//MainActivity

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.content.Intent;
import android.view.View;




public class MainActivity extends ActionBarActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home_page);

    }

    public void onClickRestaurant(View view) {
        Intent i = new Intent(MainActivity.this, MapsActivity.class);
        startActivity(i);
    }

    @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);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}
