這是一個短信篩選/批量刪除的工具類程序。
首先上圖:
1.展示全部系統短信。
2.新建篩選器(支持按號碼篩選和按內容篩選)<喎?/kf/ware/vc/" target="_blank" class="keylink">vcD4KPHA+PGltZyBzcmM9"/uploadfile/Collfiles/20141106/20141106081335131.png" alt="\">
3.篩選,批量刪除。
主要代碼:
1.獲取系統全部短信
//獲取系統全部短信 private ListgetAllSms() { final String SMS_URI_ALL = "content://sms/"; Uri uri = Uri.parse(SMS_URI_ALL); String[] projection = new String[]{"_id", "address", "body", "date"}; Cursor cursor = getContentResolver().query(uri, projection, null, null, "date desc"); int index_Id = cursor.getColumnIndex("_id"); int index_Address = cursor.getColumnIndex("address"); int index_Body = cursor.getColumnIndex("body"); int index_Date = cursor.getColumnIndex("date"); List smsList = new ArrayList (); while (cursor.moveToNext()) { SmsBean bean = new SmsBean(); bean.setId(cursor.getInt(index_Id)); bean.setFromNum(cursor.getString(index_Address)); bean.setContent(cursor.getString(index_Body)); bean.setTime(cursor.getLong(index_Date)); smsList.add(bean); } cursor.close(); return smsList; }
//新建過濾器的對話框 private void showAddFilterDialog() { AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle("添加過濾器"); View view = LayoutInflater.from(this).inflate(R.layout.add_filter_dialog, null); final EditText titleET = (EditText) view.findViewById(R.id.add_filter_dialog_title); final EditText contentET = (EditText) view.findViewById(R.id.add_filter_dialog_content); final RadioButton filterPhoneNum = (RadioButton) view.findViewById(R.id.add_filter_dialog_phoneNum); filterPhoneNum.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { contentET.setText(""); if (isChecked) { contentET.setInputType(EditorInfo.TYPE_CLASS_NUMBER); } else { contentET.setInputType(EditorInfo.TYPE_CLASS_TEXT); } } }); builder.setView(view); builder.setPositiveButton("確認", null); builder.setNegativeButton("取消", null); final AlertDialog dialog = builder.create(); dialog.show(); //點擊確定按鈕時,如果輸入不正確,則進行提示,不關閉對話框.所以此處不能使用普通的setPositiveButton進行事件監聽 dialog.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { String title = titleET.getText().toString().trim(); String content = contentET.getText().toString().trim(); if (title.equals("")) { Toast.makeText(MainActivity.this, "請輸入標題", Toast.LENGTH_SHORT).show(); return; } if (content.equals("")) { Toast.makeText(MainActivity.this, "請輸入篩選內容", Toast.LENGTH_SHORT).show(); return; } dialog.dismiss(); //添加至數據庫 DatabaseHelper helper = new DatabaseHelper(MainActivity.this); //type:篩選手機號-1,篩選短信內容-2 int type = filterPhoneNum.isChecked() ? 1 : 2; FilterBean filterBean = new FilterBean(-1, title, content, type); helper.addFilter(filterBean); Toast.makeText(MainActivity.this, "添加成功", Toast.LENGTH_SHORT).show(); //篩選 filterSms(filterBean); } }); }
//篩選符合條件的短信 private void filterSms(FilterBean filterBean) { if (smsList == null) { return; } titleTV.setText(filterBean.getTitle()); List4.刪除已選擇的短信adapterSmsList = new ArrayList (); for (SmsBean sms : smsList) { String filterContent = (filterBean.getType() == 1 ? sms.getFromNum() : sms.getContent()) .replace(" ", "").replace("-", ""); if (checkSms(filterContent, filterBean.getContent())) { adapterSmsList.add(sms); } } adapter.setList(adapterSmsList); adapter.getSelectedMap().clear(); adapter.notifyDataSetChanged(); ignoreChange = true; selectAllCB.setChecked(false); ignoreChange = false; }
//刪除已選擇的短信 private void deleteSelectedSms() { ListadapterList = adapter.getList(); SparseBooleanArray map = adapter.getSelectedMap(); final StringBuilder sb = new StringBuilder(); int count = 0; for (int i = adapterList.size() - 1; i >= 0; i--) { if (map.get(i)) { sb.append(adapterList.get(i).getId()); sb.append(","); //更新頁面 smsList.remove(adapterList.get(i)); adapterList.remove(i); map.delete(i); count++; } } Toast.makeText(this, "成功刪除了" + count + "條短信", Toast.LENGTH_SHORT).show(); //刪除 new Thread(new Runnable() { @Override public void run() { String SMS_URI_ALL = "content://sms/"; Uri uri = Uri.parse(SMS_URI_ALL); String whereClause = "_id in(" + sb.substring(0, sb.length() - 1) + ")"; int count = getContentResolver().delete(uri, whereClause, null); System.out.println("實際刪除短信" + count + "條"); } }).start(); }
5.為實現對Android 4.4的支持:
Android 4.4增加了短信權限的管理,用戶可以選擇一個“短信程序”作為默認的短信程序,而只有默認的短信程序可以執行短信數據庫“寫”的功能。
為了使自己的程序能夠出現在系統設置“默認信息程序”的列表中從而供用戶選擇,需要在Manifest中“聲明”自己的程序具備完善的信息功能,如收發短信/發彩信,當然,這些功能可以不實現(只要“聲明”了即可)。

有時候你把手機接到電腦上調試時,Android Studio總是提示你重啟ADB,但是你點重啟後,立馬又跳出那個提示重啟的對話框。會再跳出提示對話框是因為你ADB重啟沒有
SurfaceView, GLSurfaceView, SurfaceTexture和TextureView是Android當中名字比較繞,關系又比較密切的幾個類。本文基
