我的程序锁老是重复解锁界面，下面是主要代码，请大神帮忙如何解决
根据这个类来检测要运行的程序是否要解锁
public class lockTask extends TimerTask{
private static Context mContext;
private ActivityManager activityManager;
int i=0;
public lockTask(Context context){
mContext=context;
activityManager=(ActivityManager) context.getSystemService("activity");
}
public void run(){
ComponentName topActivity=activityManager.getRunningTasks(1).get(0).topActivity;
String packageName=topActivity.getPackageName();//得到要运行的程序包
boolean result=find(packageName);
if(result){
Intent intent=new Intent();
intent.putExtra("packageName",packageName);
intent.setClassName("com.example.competition","com.example.competition.unlock");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(intent);
}
}
public boolean find(String packageName){
boolean result=false;
SQLiteDatabase db=PwdDAO.getInstance().getHelper().getWritableDatabase();
if(db.isOpen()){
Cursor cursor=db.rawQuery("select packageName from tb_pname where packageName=?",new String[]{packageName});
if(cursor.moveToFirst()){
result=true;
}
cursor.close();
db.close();
}
return result;
}
public static Context getContext(){
return mContext;
}
}
这是service类
public class lockService extends Service{
private Timer mtimer;
public static final int FOREGROUND_ID=0;
public IBinder onBind(Intent arg0) {
return null;
}
private void startTimer(){
if(mtimer==null){
mtimer=new Timer();
lockTask locktask=new lockTask(this);
mtimer.schedule(locktask, 0L,100L);
}
}
public void onCreate(){
super.onCreate();
}
public int onStartCommand(Intent intent,int flags,int startId){
startForeground(FOREGROUND_ID,new Notification());
startTimer();
return super.onStartCommand(intent, flags, startId);
}
public void onDestroy(){ //当停止服务时执行
stopForeground(true);
mtimer.cancel();
mtimer.purge();
mtimer=null;
super.onDestroy();
}
}
这是解锁的代码
public class unlock extends ActionBarActivity{
String activityName;
SharedPreferences preference;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
final Intent intent=getIntent();//得到传递来的意图对象
String pName=intent.getStringExtra("packageName");
setContentView(R.layout.unlock);
preference=getSharedPreferences("password",Context.MODE_PRIVATE);
final EditText et_unlock=(EditText)findViewById(R.id.et_unlock);//获得输入密码的编辑框
Button but_unlock_ok=(Button)findViewById(R.id.but_unlock_ok);
but_unlock_ok.setOnClickListener(new OnClickListener(){
public void onClick(View v){
if(TextUtils.isEmpty(et_unlock.getText().toString())){
Toast.makeText(getBaseContext(),"密码不能为空",Toast.LENGTH_LONG).show();
}
else if(!(et_unlock.getText().toString().equals(preference.getString("pwd","")))){
Toast.makeText(getBaseContext(),"密码输入错误",Toast.LENGTH_LONG).show();
}
else{
String packageName=intent.getStringExtra("packageName");
Toast.makeText(getBaseContext(),"包名"+packageName,Toast.LENGTH_LONG).show();
PackageManager pm=getPackageManager();
Intent resolveIntent=new Intent(Intent.ACTION_MAIN);
resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> resolve=pm.queryIntentActivities(resolveIntent,PackageManager.MATCH_DEFAULT_ONLY);
Collections.sort(resolve,new ResolveInfo.DisplayNameComparator(pm));//将获取到的ResolveInfo进行排序
for(ResolveInfo reInfo:resolve){
if(reInfo.activityInfo.packageName.equals(packageName.toString())){
activityName=reInfo.activityInfo.name;//获取应用程序启动activity的名字
}
}
Intent lanchIntent=new Intent();
lanchIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
lanchIntent.setComponent(new ComponentName(packageName,activityName));
startActivity(lanchIntent);
}
}
});
}
}
