java - 不幸的是停止了谷歌地图布局

Question

当我通过点击“下一步”按钮从 addReminder Activity 移至 Google map Activity 时，我不幸遇到停止错误。我没有收到任何语法错误。请尽快回复我，我是 Android 新手。

AddReminder.java

public class AddReminder extends AppCompatActivity {

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

    public void AddEventPlace(){
        Intent intent= new Intent(this, AddEventPlace.class);
        startActivity(intent);
    }

    }

添加事件地点 XML:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.champ.remindme2.AddEventPlace" />

AddEventPlace.java

public class AddEventPlace extends FragmentActivity implement OnMapReadyCallback {

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add_event_place);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(-34, 151);
    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}}

Answer 1

将 AddEventPlace 方法更改为

public void AddEventPlace(View v){
    Intent intent= new Intent(this, AddEventPlace.class);
    startActivity(intent);
}
