Android 获取应用使用情况
效果图
先建个Unit文件夹，把下面的文件都放进去
创建文件DateTransUtils
package cn.xrick.applicationusetime.Unit; import android.util.Log; import java.text.SimpleDateFormat; import java.util.Date; public class DateTransUtils { public static final long DAY_IN_MILLIS = 24 * 60 * 60 * 1000; public static String stampToDate(long stamp){ String res; SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Date date = new Date(stamp); res = simpleDateFormat.format(date); return res; } //获取当日00:00:00的时间戳,东八区则为早上八点 public static long getZeroClockTimestamp(long time){ long currentStamp = time; currentStamp -= currentStamp % DAY_IN_MILLIS; Log.i("Wingbu"," DateTransUtils-getZeroClockTimestamp() 获取当日00:00:00的时间戳,东八区则为早上八点 :" + currentStamp); return currentStamp; } public static String milliseconds2hms(long time) { long hours = time / (1000 * 60 * 60); long minutes = (time-hours*(1000 * 60 * 60 ))/(1000* 60); long second = (time-hours*1000 * 60 * 60-minutes*1000*60)/1000; String diffTime=""; diffTime=hours+"小时"+minutes+"分"+second+"秒"; return diffTime; } }
创建文件EventUtils
package cn.xrick.applicationusetime.Unit; import android.app.usage.UsageEvents; import android.app.usage.UsageStats; import android.app.usage.UsageStatsManager; import android.content.Context; import android.util.Log; import java.text.SimpleDateFormat; import java.util.ArrayList; import java.util.Map; public class EventUtils { public static final String TAG = "EventUtils"; private static final SimpleDateFormat dateFormat = new SimpleDateFormat("M-d-yyyy HH:mm:ss"); @SuppressWarnings("ResourceType") //(Build.VERSION_CODES.LOLLIPOP) public static ArrayList<UsageEvents.Event> getEventList(Context context, long startTime, long endTime){ ArrayList<UsageEvents.Event> mEventList = new ArrayList<>(); UsageStatsManager mUsmManager = (UsageStatsManager) context.getSystemService("usagestats"); UsageEvents events = mUsmManager.queryEvents(startTime, endTime); while (events.hasNextEvent()) { UsageEvents.Event e = new UsageEvents.Event(); events.getNextEvent(e); if (e != null && (e.getEventType() == 1 || e.getEventType() == 2)) { Log.i(TAG," EventUtils-getEventList() "+e.getTimeStamp()+" event:" + e.getClassName() + " type = " + e.getEventType()); mEventList.add(e); } } return mEventList; } @SuppressWarnings("ResourceType") //(Build.VERSION_CODES.LOLLIPOP) public static ArrayList<UsageStats> getUsageList(Context context, long startTime, long endTime) { ArrayList<UsageStats> list = new ArrayList<>(); UsageStatsManager mUsmManager = (UsageStatsManager) context.getSystemService("usagestats"); Map<String, UsageStats> map = mUsmManager.queryAndAggregateUsageStats(startTime, endTime); for (Map.Entry<String, UsageStats> entry : map.entrySet()) { UsageStats stats = entry.getValue(); if(stats.getTotalTimeInForeground() > 0){ list.add(stats); Log.i(TAG," EventUtils-getUsageList() stats:" + stats.getPackageName() + " TotalTimeInForeground = " + stats.getTotalTimeInForeground()); } } return list; } }
创建文件OneTimeDetails
package cn.xrick.applicationusetime.Unit; import android.annotation.TargetApi; import android.app.usage.UsageEvents; import android.os.Build; import java.util.ArrayList; public class OneTimeDetails { private String pkgName; private long useTime; private ArrayList<UsageEvents.Event> OneTimeDetailEventList; public OneTimeDetails(String pkg, long useTime, ArrayList<UsageEvents.Event> oneTimeDetailList) { this.pkgName = pkg; this.useTime = useTime; OneTimeDetailEventList = oneTimeDetailList; } public String getPkgName() { return pkgName; } public void setPkgName(String pkgName) { this.pkgName = pkgName; } public long getUseTime() { return useTime; } public void setUseTime(long useTime) { this.useTime = useTime; } public ArrayList<UsageEvents.Event> getOneTimeDetailEventList() { return OneTimeDetailEventList; } public void setOneTimeDetailEventList(ArrayList<UsageEvents.Event> oneTimeDetailEventList) { OneTimeDetailEventList = oneTimeDetailEventList; } @TargetApi(Build.VERSION_CODES.LOLLIPOP) public String getStartTime(){ String startTime = null; if(OneTimeDetailEventList.size() > 0){ //startTime = DateUtils.formatSameDayTime(OneTimeDetailEventList.get(0).getTimeStamp(), System.currentTimeMillis(), DateFormat.MEDIUM, DateFormat.MEDIUM).toString(); startTime = DateTransUtils.stampToDate(OneTimeDetailEventList.get(0).getTimeStamp()); } return startTime; } @TargetApi(Build.VERSION_CODES.LOLLIPOP) public String getStopTime(){ String stopTime = null; if(OneTimeDetailEventList.size() > 0){ //stopTime = DateUtils.formatSameDayTime(OneTimeDetailEventList.get(OneTimeDetailEventList.size()-1).getTimeStamp(), System.currentTimeMillis(), DateFormat.MEDIUM, DateFormat.MEDIUM).toString(); stopTime = DateTransUtils.stampToDate(OneTimeDetailEventList.get(OneTimeDetailEventList.size()-1).getTimeStamp()); } return stopTime; } }
创建文件PackageInfo
package cn.xrick.applicationusetime.Unit; import android.content.Context; import android.content.pm.ApplicationInfo; import android.content.pm.PackageManager; import android.graphics.drawable.Drawable; public class PackageInfo extends android.content.pm.PackageInfo { private int mUsedCount; private long mUsedTime; private String mPackageName; private String mAppName; // private Drawable icon; public PackageInfo(int mUsedCount, long mUsedTime, String mPackageName,String appName) { this.mUsedCount = mUsedCount; this.mUsedTime = mUsedTime; this.mPackageName = mPackageName; this.mAppName=appName; //this.icon=icon; } public void addCount() { mUsedCount++; } public int getmUsedCount() { return mUsedCount; } public void setmUsedCount(int mUsedCount) { this.mUsedCount = mUsedCount; } public long getmUsedTime() { return mUsedTime; } public void setmUsedTime(long mUsedTime) { this.mUsedTime = mUsedTime; } public String getmPackageName() { return mPackageName; } public void setmPackageName(String mPackageName) { this.mPackageName = mPackageName; } public String getmAppName() { return mAppName; } public void setmAppName(String mAppName) { this.mAppName = mAppName; } public Drawable getAppIcon(Context context,String mPackageName) { PackageManager packageManager = null; ApplicationInfo applicationInfo = null; try { packageManager = context.getApplicationContext() .getPackageManager(); applicationInfo = packageManager.getApplicationInfo( mPackageName, 0); } catch (PackageManager.NameNotFoundException e) { applicationInfo = null; } Drawable icon = packageManager.getApplicationIcon(applicationInfo); //xxx根据自己的情况获取drawable return icon; } @Override public boolean equals(Object o) { //return super.equals(o); if (o == null) return false; if (this == o) return true; PackageInfo standardDetail = (PackageInfo) o; if (standardDetail.getmPackageName().equals(this.mPackageName)) { return true; } else { return false; } } @Override public int hashCode() { //return super.hashCode(); return (mPackageName + mUsedTime).hashCode(); } @Override public String toString() { return "PackageInfo{" + "mUsedCount=" + mUsedCount + ", mUsedTime=" + mUsedTime + ", mPackageName='" + mPackageName + '\'' + ", mAppName='" + mAppName + '\'' + '}'; } }
创建文件UseTimeDataManager

直接用就可以了
mUseTimeDataManager = UseTimeDataManager.getInstance(MainActivity.this); mUseTimeDataManager.refreshData(0,0); final List<PackageInfo> packageInfos = mUseTimeDataManager.getmPackageInfoListOrderByTime(); for (int i = 0; i < packageInfos.size(); i++) { Log.e("--->",i+packageInfos.get(i).getmPackageName() +" " +packageInfos.get(i).getmUsedCount()+"" +" " +milliseconds2hms(packageInfos.get(i).getmUsedTime())); }
在manifest中加入权限，打开应用之前手动打开权限，这都不会真的太菜了
