Android 实现删除短信

android的很多功能都是需要权限才能操作，还是有很多功能我们是可以直接操作的，只需要在配置文件中注明权限就行了，可是有些虽然注明了权限，但是还是会提示说你没权限。比如删除短信、让手机进入休眠状态(gotoSleep)。下面我就介绍一下我是如何删除一条属于黑名单中的短信：

1、获取你想要删除的短信的线程ID(因为我想删除最近收到的一条短信，所以我只需按时间进行倒序，然后获取第一条短信的线程ID就行了)

Java 代码

private long getThreadId() {

long threadId = 0;

String SMS_READ_COLUMN = "read";

String WHERE_CONDITION = SMS_READ_COLUMN + " = 0";

String SORT_ORDER = "date DESC";

int count = 0;

Cursor cursor = mContext.getContentResolver().query(

Uri.parse("content://sms/inbox"),

new String[] { "_id", "thread_id", "address", "person", "date", "body" },

WHERE_CONDITION,

null,

SORT_ORDER);

if (cursor != null) {

try {

count = cursor.getCount();

if (count > 0) {

cursor.moveToFirst();

threadId = cursor.getLong(1);

}

} finally {

cursor.close();

}

}

Log.i("threadId", String.valueOf(threadId));

return threadId;

}

private long getThreadId() {

long threadId = 0;

String SMS_READ_COLUMN = "read";

String WHERE_CONDITION = SMS_READ_COLUMN + " = 0";

String SORT_ORDER = "date DESC";

int count = 0;

Cursor cursor = mContext.getContentResolver().query(

Uri.parse("content://sms/inbox"),

new String[] { "_id", "thread_id", "address", "person", "date", "body" },

WHERE_CONDITION,

null,

SORT_ORDER);

if (cursor != null) {

try {

count = cursor.getCount();

if (count > 0) {

cursor.moveToFirst();
