android 读取短信格式,获取Android手机中所有短信的实现代码

以下是获取Android手机中所有短信的实现代码。需要注意的是，需要在AndroidManifest.xml文件中添加读取短信的权限。

import android.Manifest;
import android.content.ContentResolver;
import android.content.pm.PackageManager;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.Telephony;
import android.util.Log;

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;

public class MainActivity extends AppCompatActivity {

    private static final String TAG = "MainActivity";
    private static final int PERMISSIONS_REQUEST_READ_SMS = 100;

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

        // 检查权限
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS)
                != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS},
                    PERMISSIONS_REQUEST_READ_SMS);
        } else {
            readSms();
        }
    }

    private void readSms() {
        Uri smsUri = Telephony.Sms.CONTENT_URI;
        ContentResolver contentResolver = getContentResolver();
        Cursor cursor = contentResolver.query(smsUri, null, null, null, null);
        if (cursor == null) {
            Log.d(TAG, "读取短信失败");
            return;
        }
        while (cursor.moveToNext()) {
            // 读取短信内容及发送方号码
            String address = cursor.getString(cursor.getColumnIndex(Telephony.Sms.ADDRESS));
            String body = cursor.getString(cursor.getColumnIndex(Telephony.Sms.BODY));
            Log.d(TAG, "address: " + address + ", body: " + body);
        }
        cursor.close();
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                           @NonNull int[] grantResults) {
        if (requestCode == PERMISSIONS_REQUEST_READ_SMS) {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                readSms();
            } else {
                Log.d(TAG, "权限被拒绝");
            }
        }
    }
}
