這篇文章主要為大家詳細介紹了Android7.0 MTK設置默認桌面，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了Android7.0 MTK設置默認桌面的具體代碼，供大家參考，具體內容如下

項目需求:客戶安裝自己公司的桌面apk，安裝完成后自動設置為默認桌面且不彈出始終和僅一次的彈框

1.找到安裝應用的文件

frameworks\base\services\core\java\com\android\server\pm\PackageManagerService.java

 try {
   PackageParser.Package newPackage = scanPackageTracedLI(pkg, policyFlags, scanFlags,
     System.currentTimeMillis(), user);

   updateSettingsLI(newPackage, installerPackageName, null, res, user);

   if (res.returnCode == PackageManager.INSTALL_SUCCEEDED) {
 
 
    prepareAppDataAfterInstallLIF(newPackage);
 

 Log.d("yh", "pkgName " +pkgName);
 // 由于客戶的應用保密 這里使用點心桌面的包名---com.dianxinos.dxhome
 if (pkgName.equals("com.dianxinos.dxhome")){
  //發(fā)送廣播
  Intent intent = new  Intent("android.intent.action.UPDATE_LANUCHER_APPS");
  mContext.sendBroadcast(intent);
 }
    //------------------------


   } else {
    // Remove package from internal structures, but keep around any
    // data that might have already existed
    deletePackageLIF(pkgName, UserHandle.ALL, false, null,
      PackageManager.DELETE_KEEP_DATA, res.removedInfo, true, null);
   }
  } catch (PackageManagerException e) {
   res.setError("Package couldn't be installed in " + pkg.codePath, e);
  }

  Trace.traceEnd(TRACE_TAG_PACKAGE_MANAGER);
 }

2.由于設置默認桌面時，是在Settings中設置的所以廣播接收者在settings中添加并設置默認桌面（添加文件–packages\apps\Settings\src\com\android\settings下—UpdateLanucherReceiver.java）

package com.android.settings;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.ComponentName;
import android.content.IntentFilter;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import java.util.ArrayList;
import android.util.Log;
import android.content.pm.ActivityInfo;
import java.util.List;


public class UpdateLanucherReceiver extends BroadcastReceiver {
 
 public UpdateLanucherReceiver() {
 }
 
 @Override
 public void onReceive(Context context, Intent intent) {
  if (intent.getAction().equals("android.intent.action.UPDATE_LANUCHER_APPS")) {
 Log.e("yhyh" ," onReceive");
 
 final PackageManager mPm = context.getPackageManager();

   // 點心桌面的包名類名 com.dianxinos.dxhome / com.nd.hilauncherdev.launcher.Launcher設置默認桌面
 ComponentName DefaultLauncher=new ComponentName(" com.dianxinos.dxhome",
     "com.nd.hilauncherdev.launcher.Launcher");
   ArrayList<ResolveInfo> homeActivities = new ArrayList<ResolveInfo>();
   ComponentName currentDefaultHome = mPm.getHomeActivities(homeActivities);

   ComponentName[]mHomeComponentSet = new ComponentName[homeActivities.size()];
   for (int i = 0; i < homeActivities.size(); i++) {
    final ResolveInfo candidate = homeActivities.get(i);
    Log.e("yhyh","homeActivitie: candidate = "+candidate);
    final ActivityInfo activityInfo= candidate.activityInfo;
    ComponentName activityName = new ComponentName(activityInfo.packageName, activityInfo.name);
    mHomeComponentSet[i] = activityName;
   }
   IntentFilter mHomeFilter = new IntentFilter(Intent.ACTION_MAIN);
   mHomeFilter.addCategory(Intent.CATEGORY_HOME);
   mHomeFilter.addCategory(Intent.CATEGORY_DEFAULT);
   List<ComponentName>Activities=new ArrayList();
   mPm.replacePreferredActivity(mHomeFilter, IntentFilter.MATCH_CATEGORY_EMPTY,mHomeComponentSet, DefaultLauncher);
   
 //刷新桌面
  Intent intent2 = new Intent(Intent.ACTION_MAIN);
   intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
   intent2.addCategory(Intent.CATEGORY_HOME);
   context.startActivity(intent2);
 }
 }
}

3.packages\apps\Settings\AndroidManifest.xml

<!-- yh -->
 <receiver
   android:name=".UpdateLanucherReceiver" >
   <intent-filter>
    <action android:name="android.intent.action.UPDATE_LANUCHER_APPS" />
   </intent-filter>
</receiver>
