Question

我需要加载正确的布局，具体取决于方向。但问题是我不想重新加载代码，而只是重新加载布局。

我尝试setContentView(R.layout.activity_main)但是当执行该行时，我收到以下错误：

“填充类片段错误”
“复制id 0x7f0f00b9，标记为null，或者父ID为0x7f0f00a9，其他片段为com.google.android.gms.maps.SupportMapFragment”

这些错误对应于SupportMapFragment。

我是如何解决的？

此活动有android:configChanges="orientation|keyboardHidden|screenSize"因此，我想在onConfigurationChanged()

中重新加载布局

Answer 1

使用此

<com.google.android.gms.maps.MapView
    android:id="@+id/mapview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

取代：

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="0.40"
    android:layout_below="@+id/header"
    android:layout_above="@+id/linearLayout" />

在activity.java中，像这样初始化mapview：

   private MapView mapView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);
        mapView = (MapView) findViewById(R.id.mapview);
        mapView.onCreate(savedInstanceState);
        mapView.getMapAsync(this);
    }

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

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

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

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

错误膨胀SupportMapFragment onConfigurationChanged
