我有一个Android应用程序，其中包含一些活动，其中包括Google Maps Fragment，在主屏幕上有一个按钮可以打开此Maps活动，当我单击“按钮”时，它总是使该应用程序崩溃。
贝娄是主要的阶级。

buttonLogin.setOnClickListener(this);
}
private void buttonLoginClick()

startActivity (new Intent("GoogleMaps"));

}
@Override

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onClick(View v) {
switch (v.getId())

您正在获取异常：
尝试实例化不是Fragment的com.google.android.gms.maps.SupportMapFragment类–产生于：java.lang.ClassCastException
您正在使用MapActivity：GoogleMaps extends MapActivity手段，你需要处理MapFragment不SupportMapFragment
您可以通过两种方式处理此问题：
1.替换SupportMapFragment为MapFragment
<fragment
android:name="com.google.android.gms.maps.MapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
在这种情况下，您需要导入：
import android.app.Fragment;
import android.app.FragmentTransaction;
2.替换MapActivity为FragmentActivity
在这种情况下，您需要导入：
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
