## 1.抽屜控制項
SlidingDrawer：一定要配置android:handle（把手）和android:content（內容），並在子View中添加把手和內容的布局
```java
<SlidingDrawer
android:layout_width="match_parent"
android:layout_height="match_parent"
android:content="@+id/content"
android:handle="@+id/handle"
android:orientation="horizontal" >

<ImageView
android:id="@id/handle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/detail" />

<LinearLayout
android:id="@id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#22000000"
android:gravity="center"
android:orientation="vertical" >

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="我是抽屜裡面的內容" />
</LinearLayout>
</SlidingDrawer>
```
## 2.擷取總流量
```java
TrafficStats.getMobileRxBytes(); //總的移動網路下載流量
TrafficStats.getMobileTxBytes();//總的移動網路上傳流量
TrafficStats.getTotalRxBytes();//總的下載流量
TrafficStats.getTotalTxBytes();//總的網路流量
```
## 3.擷取單個應用的流量
```java
PackageManager pm = context.getPackageManager();
List<PackageInfo> packInfos = pm.getInstalledPackages(0);

packageInfo.applicationInfo.uid

TrafficStats.getUidRxBytes(int uid);//某個應用的下載流量
TrafficStats.getUidTxBytes(int uid);//某個應用的上傳流量
```
## 4.流量資訊儲存位置
上傳：/proc/uid_stat/[uid]/tcp_snd |udp_snd
下載：/proc/uid_stat/[uid]/tcp_rcv |udp_rcv

## 5.擷取檔案的數字摘要
```java
/**
* 根據檔案路徑得到檔案的md5演算法產生的數字摘要
* @param path
* @return
*/
private String getFileMd5(String path){
try {
File file = new File(path);
//得到一個數字摘要器
MessageDigest digest = MessageDigest.getInstance("MD5");
FileInputStream fis = new FileInputStream(file);
byte[] buffer = new byte[1024];
int len = 0;
while((len = fis.read(buffer))!=-1){
digest.update(buffer,0,len);
}
byte[] result = digest.digest();
StringBuilder sb = new StringBuilder();
for(byte b:result){
int number = b&0xff;
String str = Integer.toHexString(number);
if(str.length()==1){
sb.append("0");
}
sb.append(str);
}
return sb.toString();
} catch (Exception e) {
e.printStackTrace();
return "";
}
}
