Android 之 view提升 ： 八 动态获取手机权限

1. 使用ContentResolver获取手机短信信息

代码：

public class MainActivity extends AppCompatActivity {
   

    private static final int REQUEST_SMS_PERMISSION = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
   
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        LinearLayout layout = findViewById(R.id.layout);
        ListView listView = findViewById(R.id.listview);

        findViewById(R.id.btn1).setOnClickListener(new View.OnClickListener() {
   
            @Override
            public void onClick(View v) {
   
               final String SMS_URI_ALL = "content://sms/"; //所有短信
               final String SMS_URI_INBOX = "content://sms/inbox"; //收信箱
               final String SMS_URI_SEND = "content://sms/sent"; //发信箱
               final String SMS_URI_DRAFT = "content://sms/draft"; //草稿箱

                String[] items = new String[]{
   "_id", "address", "person", "body", "date", "type"};
                Uri mUri = Uri.parse(SMS_URI_INBOX);

                ArrayList<String> arrayList = new ArrayList<>();
                ContentResolver contentResolver = getContentResolver();
                Cursor cursor = contentResolver.query(mUri,items,null,null
                        ,"date desc");
                if(cursor!=null){
   
                    while(cursor.moveToNext()){
   
                        String phone = cursor.getString(cursor.getColumnIndex("address"));
                        String body = cursor.getString(cursor.getColumnIndex("body"));
                        SimpleDateFormat simpleDateFormat =
                                new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
                        Date tempDate = new Date(Long.p
