/**

public void killProcess(View view){
int total = 0;
long memorySize = 0;
for (TaskInfo userTaskInfo : usertaskinfos) {
if(userTaskInfo.isChecked()){
manager.killBackgroundProcesses(userTaskInfo.getPackName());
total ++;
memorySize += userTaskInfo.getMemorySize();

for (TaskInfo systemTaskInfo : systemtaskinfos) {
if(systemTaskInfo.isChecked()){
manager.killBackgroundProcesses(systemTaskInfo.getPackName());
total++;
memorySize += systemTaskInfo.getMemorySize();

}

Toast.makeText(getApplicationContext(), "清理了"+total+"个进程"+"释放了" + TextForMater.getKBDataSize(memorySize)+"M内存", 0).show();

fillData();
