如果呼叫来自特定号码，我想制作一个获取来电号码的应用程序，然后做一些事情。即使应用程序没有运行，我也想获取来电号码。我正在使用 BraodcastReceiver 来获取来电号码。
我有两个 java 类，一个扩展他的活动，另一个扩展 BraodcastReceiver 以获取来电号码。
扩展活动的主类：
package digicare.ringmanager;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class Main_Activity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_layout, menu);
return true;
}
}
它非常简单，并且 Number checker 类扩展了 BroadcastReceiver ：
package digicare.ringmanager;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
public class number_checker extends BroadcastReceiver {
private int ringer_mode ;
private String AM_str;
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
AudioManager AM =(AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
Log.w("start", "starting the Main_Activity");
AM_str=String.valueOf(ringer_mode);
Log.w("Ringer_mode at start", AM_str);
//setting the ringer mode on number match
try {
Bundle extras=intent.getExtras();
if (extras !=null){
String state = extras.getString(TelephonyManager.EXTRA_STATE);
Log.w("state at start",state);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)){
String phonenumber = extras.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
//AM.setRingerMode(1);
ringer_mode =AM.getRingerMode();
AM_str=String.valueOf(ringer_mode);
Log.w("Ringer_mode at ringing", AM_str);
Log.w("Number", phonenumber);
if (phonenumber.equals("1234")){
Log.w("yahoo", "Number matched");
if (ringer_mode==AudioManager.RINGER_MODE_SILENT || ringer_mode==AudioManager.RINGER_MODE_VIBRATE ){
AM.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
Log.w("Phone number is matched .!", "Now , ringer mode is normal");
int now_nor =AM.getRingerMode();
String now_nor_str=String.valueOf(now_nor);
Log.w("ring_mode at num matched",now_nor_str);
}
}
}
if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK ) || state.equals(TelephonyManager.EXTRA_STATE_IDLE)){
int now_nor =AM.getRingerMode();
String now_nor_str=String.valueOf(now_nor);
Log.w("ring_mode at offHock",now_nor_str);
if (ringer_mode==AudioManager.RINGER_MODE_NORMAL){
AM.setRingerMode(AudioManager.RINGER_MODE_NORMAL );
Log.w("Normal", "");
}else if (ringer_mode==AudioManager.RINGER_MODE_SILENT ){
AM.setRingerMode(AudioManager.RINGER_MODE_SILENT );
Log.w("silent", "");
}else if (ringer_mode==AudioManager.RINGER_MODE_VIBRATE ){
AM.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
Log.w("vibrat", "");
}
// Log.w("Again", "Now the Ringer mode is get back ");
int now =AM.getRingerMode();
String now_str=String.valueOf(now);
Log.w("ring_mode at end ",now_str);
}
}
} catch (Exception e) {
// TODO: handle exception
Log.w("MY_DEBUG_TAG", e);
}
}
}
AndroidManifist.xml 是这样的：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="digicare.ringmanager"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="5"
android:targetSdkVersion="17" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="digicare.ringmanager.Main_Activity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="number_checker" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"/>
</intent-filter>
</receiver>
</application>
</manifest>
但这不起作用，无法获取来电号码。我能做什么？？？？必须调用 number_checker 类来注册 Braodcast ???
请帮助我是一个新的安卓开发者
