AlexKolpa/fab-toolbar当我注意到动画无法正常工作时,我最近即将导入该库,即使我按照以下链接中给出的所有指示操作:

我的代码如下:

@Override

Toast.makeText(this,"This is a button click!", Toast.LENGTH_SHORT).show();
fabToolbar.hide();
}

我正在关注谷歌地图Android"入门"教程 - https://developers.google.com/maps/documentation/android/
但我遇到了一个错误""无法解析符号'OnMapReadyCallback',这可能是一个简单的修复,但令我感到困惑.这是我对应用程序的import语句的代码:
import android.app.Activity;
import android.support.v4.app.FragmentActivity;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class main extends FragmentActivity implements OnMapReadyCallback {
// Within which the entire activity is enclosed
DrawerLayout mDrawerLayout;
// ListView represents Navigation Drawer
ListView mDrawerList;
// ActionBarDrawerToggle indicates the presence of Navigation Drawer in the action bar
ActionBarDrawerToggle mDrawerToggle;
// Title of the action bar
String mTitle="";
@Override …我能够在Android Google Maps v2上为一个基本圈子制作动画,但我想向前迈进一步.我希望动画圈与Tinders动画圈类似,这可能吗？

现在,我得到一个非常不可接受的烦躁动画.这是我的代码:
public void onMapReady(GoogleMap map) {
double latitude = 33.750587;
double longitude = -84.4199173;
LatLng latLng = new LatLng(latitude,longitude);
map.moveCamera(CameraUpdateFactory.newLatLng(latLng));
map.animateCamera(CameraUpdateFactory.zoomTo(13));
map.addMarker(new MarkerOptions()
.position(new LatLng(latitude, longitude))
.title("Marker"));
final Circle circle = mMap.addCircle(new CircleOptions()
.center(new LatLng(latitude,longitude))
.radius(50).fillColor(0x5500ff00).strokeWidth(0)
);
ValueAnimator valueAnimator = new ValueAnimator();
valueAnimator.setRepeatCount(ValueAnimator.INFINITE);
valueAnimator.setRepeatMode(ValueAnimator.RESTART);
valueAnimator.setIntValues(0, 100);
valueAnimator.setDuration(1000);
valueAnimator.setEvaluator(new IntEvaluator());
valueAnimator.setInterpolator(new AccelerateDecelerateInterpolator());
valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator valueAnimator) {
float animatedFraction = valueAnimator.getAnimatedFraction();
Log.e("", "" + animatedFraction);
circle.setRadius(animatedFraction * 100);
} …
