要解决Android短信读取权限问题,需要执行以下步骤:
// 检查是否已经授予短信读取权限
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS) != PackageManager.PERMISSION_GRANTED) {
// 如果没有授予短信读取权限,请求权限
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, SMS_PERMISSION_REQUEST_CODE);
} else {
// 如果已经授予短信读取权限,执行相应操作
readSms();
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == SMS_PERMISSION_REQUEST_CODE) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// 短信读取权限已经授予,执行相应操作
readSms();
} else {
// 用户拒绝了短信读取权限,可以给出相应提示或执行其他操作
Toast.makeText(this, "未授予短信读取权限", Toast.LENGTH_SHORT).show();
}
}
}
private void readSms() {
// 使用ContentResolver查询短信数据库,获取短信内容
Uri uri = Uri.parse("content://sms/inbox");
String[] projection = new String[]{"_id", "address", "body", "date"};
Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
do {
// 处理短信数据,例如获取短信内容
String address = cursor.getString(cursor.getColumnIndex("address"));
String body = cursor.getString(cursor.getColumnIndex("body"));
long date = cursor.getLong(cursor.getColumnIndex("date"));
// 打印短信信息
Log.d(TAG, "Address: " + address + ", Body: " + body + ", Date: " + date);
} while (cursor.moveToNext());
cursor.close();
}
}
请注意,Android 6.0(API级别23)及更高版本需要动态请求短信读取权限。在上面的示例中,SMS_PERMISSION_REQUEST_CODE
是自定义的请求代码。
