android：在语言更改时重新启动应用程序而不是 activity

Question

我的申请中确实有多个活动和多个片段运行。每当我从设备语言设置更改语言环境时，只有当前 activity 会重新启动。有没有办法在设备设置下更改语言后重新启动整个应用程序？

Answer 1

您可以注册一个 BroadcastReceiver to listen for the intent ACTION_LOCALE_CHANGED，然后在收到意图后，您可以执行重新启动应用程序的逻辑。像这样：

BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        //RESTART APPLICATION
    }
 };

//register broadcastreceiver
LocalBroadcastManager.getInstance(getContext())
    .registerReceiver(mBroadcastReceiver, new IntentFilter(Intent.ACTION_LOCALE_CHANGED));

//remember to unregister in onDestroy with LocalBroadcastManager.getInstance(mContext).unregisterReceiver(mBroadcastReceiver);

要"restart"申请，可以使用：

Intent intent = new Intent(this, YourHomeActivity.class);
this.startActivity(intent);
this.finishAffinity();

开始你的家 activity 并清除所有其他活动。

或者像这样：

Intent mStartActivity = new Intent(MainActivity.this, MainActivity.class);
int mPendingIntentId = 123456;
PendingIntent mPendingIntent = PendingIntent.getActivity(MainActivity.this, mPendingIntentId, mStartActivity, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager)MainActivity.this.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
System.exit(0);

实际停止应用程序并在 100 毫秒后重新启动（将其设置为您想要的任何值）。
