The method setBuiltInZoomControls(boolean) is undefined for the type MapView

package com.googlemaps;

import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

import com.google.android.gms.maps.MapView;
import com.google.android.maps.MapActivity;


public class MainActivity extends MapActivity {

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

    MapView view= (MapView) findViewById(R.id.map);
     view.setBuiltInZoomControls(true);
}

@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);
    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();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

@Override
protected boolean isRouteDisplayed() {
    // TODO Auto-generated method stub
    return false;
}
}
Activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/map"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:name="com.google.android.gms.maps.MapFragment"
      />

 

 

解决方案:

由于我的项目在创建时的“Project Build Target"选项指定成了“Android"而没有指定为“Googlg APIs"造成的，改过来之后就解决了！

 

要新建一个target是googleAPI的模拟器
