获取手机状态:
import android.content.Context; import android.telephony.TelephonyManager; //获得相应的系统服务 TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); /** * 返回电话状态 * * CALL_STATE_IDLE 无任何状态时 * CALL_STATE_OFFHOOK 接起电话时 * CALL_STATE_RINGING 电话进来时 */ tm.getCallState(); if(tm.getCallState() == TelephonyManager.CALL_STATE_IDLE) { Log.d("test", "call state idle..."); } else if(tm.getCallState() == TelephonyManager.CALL_STATE_OFFHOOK) { Log.d("test", "call state offhook..."); } else if(tm.getCallState() == TelephonyManager.CALL_STATE_RINGING) { Log.d("test", "call state ringing..."); }
//获得相应的系统服务 TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); //使用TelephonyManager对象的listen(PhoneStateListener listener, int events) //实现PhoneStateListener listener并实现相应的方法 public class MyPhoneCallListener extends PhoneStateListener { @Override public void onCallStateChanged(int state, String incomingNumber) { switch (state) { case TelephonyManager.CALL_STATE_OFFHOOK: //电话通话的状态 Toast.makeText(Main.this, "正在通话...", Toast.LENGTH_SHORT).show(); break; case TelephonyManager.CALL_STATE_RINGING: //电话响铃的状态 Toast.makeText(Main.this, incomingNumber, Toast.LENGTH_SHORT).show(); break; } super.onCallStateChanged(state, incomingNumber); }
第一个参数需要实现PhoneStateListener listener并实现相应的方法,第二个参数是PhoneStateListener的静态常量,此处由于是监听电话状态,所以需要传入LISTEN_CALL_STATE,而同时也需要在AndroidManifest中注册相应的权限
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
