Recyclerview项目的语言更改

Question

我的Android应用程序中有多种语言支持。但是，我在recyclerview项目中看不到语言更改。

Cardview项目是我的Recyclerview项目。我活动中的其他视图完美地改变了语言。

在此视图中，recyclerview项目已单击以显示功能。

这里是代码：

我有使用相应语言的正确翻译字符串。

Answer 1

调整为您的编码样式

1）使用此-> android:configChanges="locale">

2）寄存器

  <receiver android:name=".MyBroadcast">
                <intent-filter>
                    <action android:name="android.intent.action.LOCALE_CHANGED" />
                </intent-filter>
            </receiver>

3）

  @Override
        public void onReceive(Context context, Intent intent) {
            Log.v(TAG, "onReceive: }}}}}}}}}}}}");
            if (intent != null) {
                if (intent.getAction() != null) {
                    Log.v(TAG, "onReceive: action =" + intent.getAction());
                    //android.intent.action.LOCALE_CHANGED
                    // just tell your app to finish..    
                    someActivity.finish();

                }
            }
        }
