通过aidl及反射实现挂断电话
具体分三步:
(1)ITelephony.aidl ,必须新建com.Android.internal.telephony包并放入ITelephony.aidl文件(构建后在gen下有ITelephony.java文件,这是aidl生成的接口),文件内容如下:
package com.android.internal.telephony;
interface ITelephony{
boolean endCall();
void answerRingingCall();
}
(2)在需要的类中添加如下方法,代码如下(通过反射获取电话接口的实例)
/**
* @param context
* @return
*/
private static ITelephony getITelephony(Context context) {
TelephonyManager mTelephonyManager = (TelephonyManager) context
.getSystemService(TELEPHONY_SERVICE);
Class<TelephonyManager> c = TelephonyManager.class;
Method getITelephonyMethod = null;
try {
getITelephonyMethod = c.getDeclaredMethod("getITelephony",
(Class[]) null); // 获取声明的方法
getITelephonyMethod.setAccessible(true);
} catch (SecurityException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
}
try {
ITelephony iTelephony = (ITelephony) getITelephonyMethod.invoke(
mTelephonyManager, (Object[]) null); // 获取实例
return iTelephony;
} catch (Exception e) {
e.printStackTrace();
}
return iTelephony;
}
(3)在来电时调用此实例,然后调用此endCall()方法。
mTelephonyManager = (TelephonyManager) this
.getSystemService(TELEPHONY_SERVICE);
mTelephonyManager.listen(phoneStateListener,
PhoneStateListener.LISTEN_CALL_STATE);
//电话实例
PhoneStateListener phoneStateListener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_RINGING :
iTelephony = getITelephony(getApplicationContext()); //获取电话接口
if (iTelephony != null) {
try {
iTelephony.endCall(); // 挂断电话
Toast.makeText(getApplicationContext(),
"endCall "+ incomingNumber +" successful!", 3000).show();
} catch (RemoteException e) {
e.printStackTrace();
}
}
break;
default :
break;
}
}
};
//注意:在功能清单文件中添加电话的权限:
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
