更新完google play servise 出現Android.r檔無法匯入

為了使用新的google map
必須裝新版的google service
裝完必須更新eclipse
最後要使用android tools ->add support library
解決

zxing

library 用zxing2.1版本
1匯入project "android"
2把core裡面的core.jar放到上1步驟專案的  新建一個libs資料夾下 就沒有錯誤了
3.右鍵點專案選porperty -> android ->islibrary鉤起來
4.到自已專案 porperty-> android ->add library
5.記得把activity加入自己專案
6.Intent intent = new Intent(getActivity(),
      CaptureActivity.class);
      // Intent intent = new
      // Intent("com.google.zxing.client.android.SCAN");
      intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
      startActivityForResult(intent, 0);

//接收訊息
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
  Log.d("tf", "resultCode = " + resultCode);
  if (requestCode == 0) {
   if (resultCode == 1) {
    // Handle successful scan
    String capturedQrValue = intent.getStringExtra("RESULT");
    //String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
  //   Toast.makeText(FragQRCodeScan.this,"Scan Result:" + capturedQrValue, Toast.LENGTH_SHORT).show();

   } else if (resultCode == 2) {
   // Handle cancel
   }
  } else {

  }
 }

android AlertDialog.Builder listview 未整理 (夜市人生phone的ListViewAdapter_Frag_ShopBills.java)

//get data //不同張訂單 AlertDialog.Builder builder = new AlertDialog.Builder(mActivity); builder.setTitle("增加備註"); builder.setMultiChoiceItems(arr_ClassMemoName, arr_isClick, new OnMultiChoiceClickListener(){ @Override public void onClick(DialogInterface dialog, int which,boolean isChecked) { arr_isClick[which] = isChecked; } }); //按下確定 builder.setPositiveButton("確定",new DialogInterface.OnClickListener(){ public void onClick(DialogInterface arg0, int arg1) { //增加備註 for(int i=0;i< arr_isClick.length;i++){ if(arr_isClick[i]==true){ list_SingleBills.get(position).list_ClassMemo.add(arr_ClassMemoID[i]);//把勾選備註加進來 int ClassMemoPrice = Integer.parseInt(list_ClassMemo.get(i).str_Price);//該個備註價錢 arr_i_productMemoPrice[position] += ClassMemoPrice;//加到總備註 }else{ //取消備註 // ArrayList temp_list_ClassMemo = list_SingleBills.get(position).list_ClassMemo; for(int j = 0 ; j < list_SingleBills.get(position).list_ClassMemo.size() ; j++) { if(list_SingleBills.get(position).list_ClassMemo.get(j).equals(arr_ClassMemoID[i])) { list_SingleBills.get(position).list_ClassMemo.remove(j); } } } } listViewAdapter_Frag_GoodsList.notifyDataSetChanged();//刷新自己 } }); builder.setNegativeButton("取消",new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { dialog.cancel(); } }); builder.show();

當listview裡面有button checkbox元件 onItemClick事件會失效
