如何为Angular Material 2对话框设置动画？
我尝试使用正常的Angular 2+动画理论。它可以工作，但会发生什么是对话框上的元素被动画化（如预期的那样），对话框就会停留。但我想要的是对话框本身应该动画，例如，不透明度应该在几秒钟内从1变为0。
我还检查了public class AnaMenu extends AppCompatActivity {
public static final int MENU_Ara = Menu.FIRST + 1;
OyunTextView oyunTextView;
static final int AnketDegerlendirmesi = 1337;
int selectedPosition ;
String[] afteractivitydialogitems;
int toplamaislemi;
String[] dialogdegerleri;
boolean[] dialogcheckeditems;
String toast;
TextView sayılar;
ListView liste;
int a = 60 ;
ArrayList<String> kullanıcısayıdegerlistesi = new ArrayList<>();
ArrayList<Integer> mUserselecteditems = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ana_menu);
liste = (ListView) findViewById(R.id.oyun);
//Adapter im.
oyunTextView = new OyunTextView();
liste.setAdapter(oyunTextView);
registerForContextMenu(liste);
afteractivitydialogitems = getResources().getStringArray(R.array.anket);
dialogcheckeditems = new boolean[afteractivitydialogitems.length];
dialogdegerleri = getResources().getStringArray(R.array.anketdeğer);
//show the first activity when First time launched application.
SharedPreferences prefs = this.getSharedPreferences("MyAppPrefs", MODE_PRIVATE);
boolean settingsFilled = prefs.getBoolean("SettingsFilled", false);
if (!settingsFilled){
Intent sa = new Intent(AnaMenu.this,MainActivity.class);
startActivity(sa);
SharedPreferences pr = this.getSharedPreferences("MyAppPrefs", MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putBoolean("SettingsFilled", true);
editor.commit();
}
}
class OyunTextView extends BaseAdapter {
@Override
public int getCount() {
Intent i = getIntent();
final ArrayList<String> secilmis = i.getStringArrayListExtra("listem");
return secilmis.size();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = getLayoutInflater().inflate(R.layout.oyuntextview, null);
TextView namesbox = (TextView) convertView.findViewById(R.id.isim);
sayılar = (TextView) convertView.findViewById(R.id.sayı);
Intent i = getIntent();
final ArrayList<String> secilmis = i.getStringArrayListExtra("listem");
for (int defa = 0; defa < secilmis.size(); defa++) {
kullanıcısayıdegerlistesi.add("50");
// if (kullanıcısayıdegerlistesi.contains("50")){sayılar.setTextColor(getResources().getColor(R.color.elli));}
}
namesbox.setText(secilmis.get(position));
sayılar.setText(kullanıcısayıdegerlistesi.get(position));
sayılar.setTextColor(getResources().getColor(R.color.elli));
convertView.setBackgroundColor(getResources().getColor(R.color.yüz));
return convertView;
}
}
方法是否有任何动画选项，但似乎没有。
将对话框的不透明度从1设置为0（例如在关闭它之前）是一个常见的用例，如何使用Angular Material 2对话框实现它？
