殺毒引擎：

 * (non-Javadoc)
 * @see android.app.Activity#onTouchEvent(android.view.MotionEvent)
 */
@Override
public boolean onTouchEvent(MotionEvent event) {
 packagenames = new ArrayList<String>();
 virusResult = new ArrayList<String>();
 infos = new ArrayList<ApplicationInfo>();
 animationDrawable.start();//播放掃描病毒的動畫
 new Thread(){
  @Override
  public void run() {
   try {
    URL url = new URL("http://192.168.1.168:8080/virus.xml");
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();

    handler.sendMessage(msg);
   } catch (Exception e) {
    e.printStackTrace();
   }
  }
 }.start();
 return super.onTouchEvent(event);
}

顯示病毒掃描信息：

Handler handler = new Handler(){
 @Override
 public void handleMessage(Message msg) {
  super.handleMessage(msg);
  switch (msg.what) {
  case SCANNING:
   StringBuilder sb = (StringBuilder) msg.obj;
   tv_killvirus_info.setText(sb.toString());
   sv.scrollBy(0, 25);//每次增加都會自動向下移動畫面
   break;
  case SCANNING_FINISH:
   int i = (Integer) msg.obj;
   StringBuilder sb1 = new StringBuilder();
   sb1.append("掃描完畢 共掃描 "+ i+ " 個程序");
   if(virusResult.size()>0){
    sb1.append("發(fā)現(xiàn)病毒 \n");
     for(String packname : virusResult){
      sb1.append("病毒名"+ packname);
      sb1.append("\n");
     }
    }
    tv_killvirus_info.setText(sb1.toString());
    animationDrawable.stop();
   break;
  }
 }
};

獲取到程序的簽名：

/*
 * 獲取程序的簽名
 */
public String getAppSignature(String packname){
  try {
   PackageInfo packinfo =pm.getPackageInfo(packname, PackageManager.GET_SIGNATURES);
   //獲取到所有的權(quán)限
   return packinfo.signatures[0].toCharsString();
  } catch (NameNotFoundException e) {
   e.printStackTrace();
   return null;
  }
}

顯示掃描的文件頁面并自動滾動：

<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/iv_killvirus_am"
android:id="@+id/sv_killvirus"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/tv_killvirus_info"
></TextView>
</ScrollView>

希望本文所述對大家Android程序設(shè)計有所幫助。
