檢查鈴聲模式

要檢查鈴聲模式: 正常，振動，靜音; 可以使用 AudioManager.

調用 getSystemService(AUDIO_SERVICE) 方法, 獲取 audioManager 對象, 再調用 audioManager 對象的 getRingerMode() 方法便可檢查目前的鈴聲模式.

package com.AndroidRinger;

import android.app.Activity;
import android.media.AudioManager;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class AndroidRinger extends Activity {

private AudioManager audioManager;

  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
      Button buttonRinger = (Button)findViewById(R.id.buttonringer);
      final TextView textRingerState = (TextView)findViewById(R.id.textringerstate);
    
      audioManager = (AudioManager)getSystemService(AUDIO_SERVICE);
    
      buttonRinger.setOnClickListener(new Button.OnClickListener(){

  @Override
  public void onClick(View arg0) {
   // TODO Auto-generated method stub
   int ringerMode = audioManager.getRingerMode();
   if(ringerMode == AudioManager.RINGER_MODE_SILENT){
         textRingerState.setText("Ringer is Silent");
   }else if (ringerMode == AudioManager.RINGER_MODE_VIBRATE){
    textRingerState.setText("Ringer is Vibrate");
   }else{
    textRingerState.setText("Ringer is Normal");
   }
  }});
    
  }
}
