推荐答案

通过在 TelephonyManager 上使用 PhoneStateListener 进行监听，可以检索信号信息。



像这样的东西会听取信号强度并将其记录到 LogCat ;

Signal information can be retrieved by listening using a PhoneStateListener on a TelephonyManager.

Something like this will listen to signal strength and log it to LogCat;

package com.bornander.signaltest;

import android.os.Bundle;
import android.telephony.PhoneStateListener;
import android.telephony.SignalStrength;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.app.Activity;
import android.content.Context;

public class MainActivity extends Activity {
	
  public class MyListener extends PhoneStateListener {
    @Override
    public void onSignalStrengthsChanged(final SignalStrength signalStrength) {
      super.onSignalStrengthsChanged(signalStrength);
      Log.i("SIGNAL", String.format("Strength=%s", signalStrength));
    }
  }

  @Override
  protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    TelephonyManager telephonyManager =
     (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);  
    
    telephonyManager.listen(
        new MyListener(), 
        PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);
  }
}

请注意，您应该在获得许可的情况下归档您的清单;

Note that you should attribute up your manifest with permission;

<uses-permission Android:name="android.permission.READ_PHONE_STATE" />

希望这会有所帮助，
