java - Android 应用主题改变时的波纹类动画

Question

我想添加相同的主题变化动画

(这是电报应用程序)

我有一个radioGroup

onChangeListener 改变主题的地方
我想实现这个:
当勾选Dark radio时，动画会从dark radio的位置开始
如果你检查光，它会从光等开始
怎么可能在andoid app中做出这样的动画？
我的完整主题转换代码:

public void chooseTheme(MenuItem item) {
        final AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);
        final View mView = getLayoutInflater().inflate(R.layout.dialog_theme,null);
        Button btn_cancel = mView.findViewById(R.id.btn_cancel);
        Button btn_okay = mView.findViewById(R.id.btn_okay);
        alert.setView(mView);
        final AlertDialog alertDialog = alert.create();
        alertDialog.setCanceledOnTouchOutside(false);
        final RadioGroup themeGroup = mView.findViewById(R.id.themeGroup);

        btn_cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                alertDialog.dismiss();
            }
        });
        themeGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @SuppressLint("NonConstantResourceId")
            @Override
            public void onCheckedChanged(RadioGroup themeGroup, int i) {
                switch(i) {
                    case R.id.radioLight:
                        AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);
                        setTheme(R.style.AppTheme);
                        Toast.makeText(getApplicationContext(),"Light mode",Toast.LENGTH_LONG).show();
                        restartApp();
                        break;
                    case R.id.radioDark:
                        AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
                        setTheme(R.style.darkTheme);
                        Toast.makeText(getApplicationContext(),"Dark mode", Toast.LENGTH_LONG).show();
                        restartApp();
                        break;
                    case R.id.radioSystem:
                        AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM);
                        Toast.makeText(getApplicationContext(),"System mode", Toast.LENGTH_LONG).show();
                        restartApp();
                        break;
                }
            }
        });
        btn_okay.setOnClickListener(new View.OnClickListener() {
            @SuppressLint("SetTextI18n")
            @Override
            public void onClick(View v) {

                alertDialog.dismiss();
            }
        });
        alertDialog.show();
    }
    public void restartApp() {
        Intent i = new Intent(getApplicationContext(),MainActivity.class);
        startActivity(i);
        finish();
    }

查看我的 github 库:https://github.com/imandolatkia/Android-Animated-Theme-Manager

在此库中，您可以创建自定义主题并使用涟漪动画动态更改它们，如您的问题图片。
