我正在使用FragmentActivity来加载地图。在Java类中,执行setContentView时出错。我的Mapsreen.java代码如下: 在一些设备上运行良好,在Marshmallow上会崩溃。还有其他原因吗?
public class MapScreen extends FragmentActivity implements LocationListener,
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_screen);
....
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
googleMap = fm.getMap();
}
and my xml has fragment using SupportMapFragment as well. map_screen.xml is like :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" />
<ImageView
android:id="@+id/startActivityButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:layout_marginBottom="44dp"
android:background="@drawable/end_meetup_btn"
/>
</RelativeLayout>
我找不到同样的问题。在Marshmallow中出现崩溃:“二进制XML文件第7行:充气类片段错误”。请给出建议!尝试查找“Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.io.File.mkdir()' on a null object reference”。
