步骤-4
在“所有活动”中添加以下代码
@Override
protected void onCreate(Bundle savedInstanceState) {
if (CommonUtils.isNightModeEnabled(MainActivity.this)) {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
} else {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);
}
super.onCreate(savedInstanceState);
...
//your code
}
步骤-5
使用以下代码更改模式
private WeakReference<Activity> mActivity;
binding.imgNightMode.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mActivity = new WeakReference<Activity>(MainActivity.this);
CommonUtils.setIsToogleEnabled(MainActivity.this, true);
if (CommonUtils.isNightModeEnabled(MainActivity.this)) {
CommonUtils.setIsNightModeEnabled(MainActivity.this, false);
mActivity.get().recreate();
} else {
CommonUtils.setIsNightModeEnabled(MainActivity.this, true);
mActivity.get().recreate();
}
}
});
我希望这能帮助你
谢谢。从AppCompat v1.1.0开始,setDefaultNightMode()会自动重新创建任何已启动的活动。
private WeakReference<Activity> mActivity;
binding.imgNightMode.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mActivity = new WeakReference<Activity>(MainActivity.this);
CommonUtils.setIsToogleEnabled(MainActivity.this, true);
if (CommonUtils.isNightModeEnabled(MainActivity.this)) {
CommonUtils.setIsNightModeEnabled(MainActivity.this, false);
mActivity.get().recreate();
} else {
CommonUtils.setIsNightModeEnabled(MainActivity.this, true);
mActivity.get().recreate();
}
}
});
