android - 如何隐藏 map fragment - Android

Question

使用下面的代码show 和hide MapFragment，效果很好:

public class MapFragmentActivity extends FragmentActivity {
...........
mMapFragment = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map));
googleMap = mMapFragment.getMap();  
googleMap.setMyLocationEnabled(true);
.....
if(isChecked)
  {                                 
        mMapFragment.getView().setVisibility(View.VISIBLE);                                     
  }
  else 
  {
        mMapFragment.getView().setVisibility(View.GONE);
  }

但是每当我将它与Animation 一起使用时，Map 永远不会隐藏，它始终可见，而动画对我有用；

if(isChecked)
    {               
        mMapFragment.getView().setVisibility(View.VISIBLE);
        mMapFragment.getView().startAnimation(AnimationUtils.loadAnimation(MapFragmentActivity.this,
         R.anim.slide_up));
    }
    else 
    {
        mMapFragment.getView().setVisibility(View.GONE);
        mMapFragment.getView().startAnimation(AnimationUtils.loadAnimation(MapFragmentActivity.this,
         R.anim.slide_down));
    }

你可以试试这个

      private GoogleMap mMap;
    private SupportMapFragment mMapFragment;

if(isCheked) {
       mMapFragment = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.mapFragment));
    mMap = mMapFragment.getMap();
    
    mMapFragment.getView().setVisibility(View.Visible);
 
}
else {
   mMapFragment = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.mapFragment));
    mMap = mMapFragment.getMap();
    
    mMapFragment.getView().setVisibility(View.INVISIBLE);

}

或者简单的方法是:

    if(isCheked) {
getSupportFragmentManager().beginTransaction().show(mFragment).commit();
               
        }
        else {
          getSupportFragmentManager().beginTransaction().hide(mFragment).commit();
        }

尝试一下，如果有效请告诉我。

这是 Kotlin 中第一个方法的 fragment ...

val mapFragment = supportFragmentManager
                .findFragmentById(R.id.map) as SupportMapFragment?
mapFragment?.view?.visibility = View.GONE
