获取Android设备上的短信通常涉及访问设备的“SMS”内容提供者。以下是一个简单的示例代码，展示如何在Android中读取短信。此示例代码需在具有相关权限的前提下才能正常工作。

添加权限到AndroidManifest.xml文件：

<uses-permission android:name="android.permission.READ_SMS"/>
<uses-permission android:name="android.permission.RECEIVE_SMS"/>

在代码中请求权限（对于Android 6.0及以上版本）：

if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS) != PackageManager.PERMISSION_GRANTED) {
 ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, 1);
}

实现读取短信的功能：

import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.Telephony;
import androidx.appcompat.app.AppCompatActivity;
import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

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

     if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS) == PackageManager.PERMISSION_GRANTED) {
         readSms();
     } else {
         ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, 1);
     }
 }

 private void readSms() {
     Uri smsUri = Telephony.Sms.CONTENT_URI;
     String[] projection = new String[]{"_id", "address", "body", "date"};
     Cursor cursor = getContentResolver().query(smsUri, projection, null, null, "date DESC");

     if (cursor != null && cursor.moveToFirst()) {
         ArrayList<String> smsList = new ArrayList<>();
         do {
             String address = cursor.getString(cursor.getColumnIndexOrThrow("address"));
             String body = cursor.getString(cursor.getColumnIndexOrThrow("body"));
             String date = cursor.getString(cursor.getColumnIndexOrThrow("date"));
             
             smsList.add("Address: " + address + "nBody: " + body + "nDate: " + date);
         } while (cursor.moveToNext());

         cursor.close();
         // Now, smsList contains all your messages, and you can process them as needed
     }
 }
}
