Android 11.0 长按按键切换SIM卡默认移动数据

近来收到客户需求想要通过长按按键实现切换SIM卡默认移动数据的功能，该功能主要通过长按按键发送广播来实现，具体修改参照如下：

首先创建广播，具体修改参照如下：

/vendor/mediatek/proprietary/packages/apps/MtkSettings/AndroidManifest.xml
 

+       <receiver
+            android:name=".sim.SimReceiver">
+            <intent-filter>
+                <action android:name="android.intent.action.sim.longpress" />
+            </intent-filter>
+        </receiver>

其次合入具体功能实现的SimReceiver.java文件：

/vendor/mediatek/proprietary/packages/apps/MtkSettings/src/com/android/settings/sim/SimReceiver.java

package com.android.settings.sim;import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.media.RingtoneManager;
import android.net.Uri;
import android.telephony.SubscriptionInfo;
import android.telephony.SubscriptionManager;
import android.util.Log;
import java.util.List;public class SimReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {if (intent.getAction().equals("android.intent.action.sim.longpress")) {SubscriptionManager subscriptionManager = SubscriptionManager.from(context);List<SubscriptionInfo> subscriptionInfoList = subscriptionManager.getActiveSubscriptionInfoList();if (subscriptionInfoList != null && subscriptionInfoList.size() > 1) {int subId1 = subscriptionInfoList.get(0).getSubscriptionId();int subId2 = subscriptionInfoList.get(1).getSubscriptionId();if (SubscriptionManager.getDefaultDataSubscriptionId() == subId1){subscriptionManager.setDefaultDataSubId(subId2);} else if (SubscriptionManager.getDefaultDataSubscriptionId() == subId2){subscriptionManager.setDefaultDataSubId(subId1);}}}}
}

然后配置对应按键长按发送广播，具体修改参照如下：

/frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java

+            case KeyEvent.KEYCODE: {
+                if (down) {
+		    Handler mHandler = new Handler();
+                    mHandler.postDelayed(new Runnable() {
+                        public void run() {
+                            sendBC("android.intent.action.sim.longpress");
+                        }
+                    }, 2 * 1000);
+                }+    private void sendBC(String action) {
+        Intent intent = new Intent();
+        intent.setAction(action);
+        intent.addFlags(0x01000000);
+        mContext.sendBroadcast(intent);
+    }

最后注册接收广播：

/vendor/mediatek/proprietary/packages/apps/MtkSettings/src/com/android/settings/sim/SimDialogActivity.java

+import android.content.IntentFilter;protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);showOrUpdateDialog();
+	SimReceiver aSimReceiver = new SimReceiver();
+       IntentFilter intentFilter = new IntentFilter();
+       intentFilter.addAction("android.intent.action.sim.longpress");
+       registerReceiver(aSimReceiver ,intentFilter);}

重新编译验证，修改生效，已实现通过长按按键切换SIM卡默认移动数据功能
