Android：短信 筛选/批量删除 程序（支持Android 2.3~4.4）

这是一个短信筛选/批量删除的工具类程序。

首先上图：

1.展示全部系统短信。



2.新建筛选器（支持按号码筛选和按内容筛选）



3.筛选，批量删除。



主要代码：

1.获取系统全部短信

//获取系统全部短信
private List<SmsBean> getAllSms() {
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<SmsBean> smsList = new ArrayList<SmsBean>();
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;
}

2.添加筛选器的对话框

//新建过滤器的对话框
private void showAddFilterDialog() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("添加过滤器");

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("确认", null);
builder.setNegativeButton("取消", null);
final AlertDialog dialog = builder.create();
dialog.show();

//点击确定按钮时，如果输入不正确，则进行提示，不关闭对话框.所以此处不能使用普通的setPositiveButton进行事件监听
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, "请输入标题", Toast.LENGTH_SHORT).show();
return;
}
if (content.equals("")) {
Toast.makeText(MainActivity.this, "请输入筛选内容", Toast.LENGTH_SHORT).show();
return;
}

dialog.dismiss();

//添加至数据库
DatabaseHelper helper = new DatabaseHelper(MainActivity.this);
//type:筛选手机号-1，筛选短信内容-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();

//筛选
filterSms(filterBean);
}
});
}

3.短信筛选

//筛选符合条件的短信
private void filterSms(FilterBean filterBean) {
if (smsList == null) {
return;
}

titleTV.setText(filterBean.getTitle());
List<SmsBean> adapterSmsList = new ArrayList<SmsBean>();
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;
}

4.删除已选择的短信

//删除已选择的短信
private void deleteSelectedSms() {
List<SmsBean> adapterList = 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(",");

//更新页面
smsList.remove(adapterList.get(i));
adapterList.remove(i);
map.delete(i);

count++;
}
}

Toast.makeText(this, "成功删除了" + count + "条短信", Toast.LENGTH_SHORT).show();

//删除
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("实际删除短信" + count + "条");
}
}).start();
}

5.为实现对Android 4.4的支持：

      Android 4.4增加了短信权限的管理，用户可以选择一个“短信程序”作为默认的短信程序，而只有默认的短信程序可以执行短信数据库“写”的功能。

     为了使自己的程序能够出现在系统设置“默认信息程序”的列表中从而供用户选择，需要在Manifest中“声明”自己的程序具备完善的信息功能，如收发短信/发彩信，当然，这些功能可以不实现（只要“声明”了即可）。

<!--以下代码为实现在Android 4.4上删除短信。对于Android 4.4以下的设备无需这些代码。-->
